Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

[PATCH] drivers/scsi/ahci: add #include req'd for the DMA_{64,32}BIT_MASK constants The previous patch did not compile cleanly on all architectures so here's a fixed one which #includes <linux/dma-mapping.h>. Use the DMA_{64,32}BIT_MASK constants from dma-mapping.h when calling pci_set_dma_mask() or pci_set_consistent_dma_mask() This patch includes dma-mapping.h explicitly because it caused errors on some architectures otherwise.

ahci: ahci: implement workaround for ASUS P5W-DH Deluxe ahci_broken_hardreset(), take #2 P5W-DH Deluxe has ICH9 which doesn't have PMP support but SIMG 4726 hardwired to the second port of AHCI controller at PCI device 1f.2. The 4726 doesn't work as PMP but as a storage processor which can do hardware RAID on downstream ports. When no device is attached to the downstream port of the 4726, pseudo ATA device for configuration appears. Unfortunately, ATA emulation on the device is very lousy and causes long hang during boot. This patch implements workaround for the board. If the mainboard is P5W-DH Deluxe (matched using DMI), only hardreset is used on the second port of AHCI controller @ 1f.2 and the hardreset doesn't depend on receiving the first FIS and just proceed to IDENTIFY. This workaround fixes bugzilla #8923. http://bugzilla.kernel.org/show_bug.cgi?id=8923 Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

#include <linux/dmi.h>
include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

ahci: Add generic MSI-X support for single interrupts to SATA PCI driver This patch adds generic MSI-X support for single interrupts to the SATA PCI driver. MSI-X support is needed for host controller that only have MSI-X support implemented, but no MSI or intx. This patch only adds support for single interrupts, multiple per-port MSI-X interrupts are not yet implemented. The new implementation still initializes MSIs first. Only if that fails, the code tries to enable MSI-X. If that fails too, setup is continued with intx interrupts. To not break other chips by this generic code change, there are the following precautions: * Interrupt ranges are not enabled at all. * Only single interrupt mode is enabled for msix cap devices. Thus, only one interrupt will be setup. * During the discussion with Tejun we agreed to change the init sequence from msix-msi-intx to msi-msix-intx. Thus, if a device offers msi and init does not fail, the msix init code will not be executed. This is equivalent to current code. With this, the code only setups single mode msix as a last resort if msi fails. No interrupt range is enabled at all. Only one interrupt will be enabled. tj: comment edits. Changes of the patch series: v5: * updated patch subject that the patch only implements single IRQ * moved Cavium specific code to a separate patch * detect Cavium ThunderX device with PCI_CLASS_STORAGE_SATA_AHCI instead of vendor/dev id * added more comments to the code * enable single msix support for all kind of devices (removing strict check) * rebased onto update libata/for-4.2 with patch 1, 2 applied v4: * removed implementation of ahci_init_intx() * improved patch descriptions * rebased onto libata/for-4.2 v3: * store irq number in struct ahci_host_priv * change initialization order from msix-msi-intx to msi-msix-intx * improve comments in ahci_init_msix() * improve error message in ahci_init_msix() * do not enable MSI-X if MSI is actively disabled for the device v2: * determine irq vector from pci_dev->msi_list Based on a patch from Sunil Goutham <sgoutham@cavium.com>.

The controller resides on the SoC and is a AHCI compatible SATA controller with one port, compliant with Serial ATA 3.1 and AHCI Revision 1.31. There can exists multiple SATA controllers on the SoC. The controller depends on MSI-X support since the PCI ECAM controller on the SoC does not implement MSI nor lagacy intx interrupt support. Thus, during device initialization, if MSI fails MSI-X will be used to enable the device's interrupts. The controller uses non-standard BAR0 for its register range. The already existing device lookup (vendor and device id) that is already implemented for other host controllers is used to change the PCI BAR.

We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

ahci: Add runtime PM support for the host controller This patch adds runtime PM support for the AHCI host controller driver so that the host controller is powered down when all SATA ports are runtime suspended. Powering down the AHCI host controller can reduce power consumption and possibly allow the CPU to enter lower power idle states (S0ix) during runtime. Runtime PM is blocked by default and needs to be unblocked from userspace as needed (via power/* sysfs nodes).

libata: make reset related methods proper port operations Currently reset methods are not specified directly in the ata_port_operations table. If a LLD wants to use custom reset methods, it should construct and use a error_handler which uses those reset methods. It's done this way for two reasons. First, the ops table already contained too many methods and adding four more of them would noticeably increase the amount of necessary boilerplate code all over low level drivers. Second, as ->error_handler uses those reset methods, it can get confusing. ie. By overriding ->error_handler, those reset ops can be made useless making layering a bit hazy. Now that ops table uses inheritance, the first problem doesn't exist anymore. The second isn't completely solved but is relieved by providing default values - most drivers can just override what it has implemented and don't have to concern itself about higher level callbacks. In fact, there currently is no driver which actually modifies error handling behavior. Drivers which override ->error_handler just wraps the standard error handler only to prepare the controller for EH. I don't think making ops layering strict has any noticeable benefit. This patch makes ->prereset, ->softreset, ->hardreset, ->postreset and their PMP counterparts propoer ops. Default ops are provided in the base ops tables and drivers are converted to override individual reset methods instead of creating custom error_handler. * ata_std_error_handler() doesn't use sata_std_hardreset() if SCRs aren't accessible. sata_promise doesn't need to use separate error_handlers for PATA and SATA anymore. * softreset is broken for sata_inic162x and sata_sx4. As libata now always prefers hardreset, this doesn't really matter but the ops are forced to NULL using ATA_OP_NULL for documentation purpose. * pata_hpt374 needs to use different prereset for the first and second PCI functions.

ahci: fix module refcount breakage introduced by libahci split libata depends on scsi_host_template for module reference counting and sht's should be owned by each low level driver. During libahci split, the sht was left with libahci.ko leaving the actual low level drivers not reference counted. This made ahci and ahci_platform always unloadable even while they're being actively used. Fix it by defining AHCI_SHT() macro in ahci.h and defining a sht for each low level ahci driver. stable: only applicable to 2.6.35.

libata: implement and use ops inheritance libata lets low level drivers build ata_port_operations table and register it with libata core layer. This allows low level drivers high level of flexibility but also burdens them with lots of boilerplate entries. This becomes worse for drivers which support related similar controllers which differ slightly. They share most of the operations except for a few. However, the driver still needs to list all operations for each variant. This results in large number of duplicate entries, which is not only inefficient but also error-prone as it becomes very difficult to tell what the actual differences are. This duplicate boilerplates all over the low level drivers also make updating the core layer exteremely difficult and error-prone. When compounded with multi-branched development model, it ends up accumulating inconsistencies over time. Some of those inconsistencies cause immediate problems and fixed. Others just remain there dormant making maintenance increasingly difficult. To rectify the problem, this patch implements ata_port_operations inheritance. To allow LLDs to easily re-use their own ops tables overriding only specific methods, this patch implements poor man's class inheritance. An ops table has ->inherits field which can be set to any ops table as long as it doesn't create a loop. When the host is started, the inheritance chain is followed and any operation which isn't specified is taken from the nearest ancestor which has it specified. This operation is called finalization and done only once per an ops table and the LLD doesn't have to do anything special about it other than making the ops table non-const such that libata can update it. libata provides four base ops tables lower drivers can inherit from - base, sata, pmp, sff and bmdma. To avoid overriding these ops accidentaly, these ops are declared const and LLDs should always inherit these instead of using them directly. After finalization, all the ops table are identical before and after the patch except for setting .irq_handler to ata_interrupt in drivers which didn't use to. The .irq_handler doesn't have any actual effect and the field will soon be removed by later patch. * sata_sx4 is still using old style EH and currently doesn't take advantage of ops inheritance.

[PATCH] ahci: ignore PORT_IRQ_IF_ERR on JMB controllers JMicron AHCI controllers set PORT_IRQ_IF_ERR on device errors. The IRQ status bit indicates interface error or protocol mismatch and ahci driver interprets it into AC_ERR_ATA_BUS. So, whenever an ATAPI device raises check condition, ahci interprets it as ATA bus error and thus resets it which, in turn, raises check condition thus creating a reset loop and rendering the device unuseable. This patch makes JMB controllers ignore PORT_IRQ_IF_ERR when interpreting error condition. Signed-off-by: Tejun Heo <htejun@gmail.com> Cc: Justin Tsai <justin@jmicron.com>

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

When PI and cat.n_ports are inconsistent, honor cap.n_ports and force port_map to be ((1 << cap.n_ports) - 1). 3. There were two separate places dealing with port_map. Unify them to one. As all newer ahci chips seem to get PI correct and older ones usually have zero PI. Controllers with holes in PI are very unlikely to screw up PI, so #2 makes more sense than following inconsistent PI. Without this change, not setting ATA_FLAG_HONOR_PI when it's needed results in weird detection failure. This changed logic should be able to handle all known cases correctly automatically.

ahci: avoton port-disable reset-quirk Avoton AHCI occasionally sees drive probe timeouts at driver load time. When this happens SCR_STATUS indicates device detected, but no D2H FIS reception. Reset the internal link state machines by bouncing port-enable in the PCS register when this occurs.

PCI: Disable async suspend/resume for JMicron multi-function SATA/AHCI On multi-function JMicron SATA/PATA/AHCI devices, the PATA controller at function 1 doesn't work if it is powered on before the SATA controller at function 0. The result is that PATA doesn't work after resume, and we print messages like this: pata_jmicron 0000:02:00.1: Refused to change power state, currently in D3 irq 17: nobody cared (try booting with the "irqpoll" option) Async resume was introduced in v3.15 by 76569faa62c4 ("PM / sleep: Asynchronous threads for resume_noirq"). Prior to that, we powered on the functions in order, so this problem shouldn't happen. e6b7e41cdd8c ("ata: Disabling the async PM for JMicron chip 363/361") solved the problem for JMicron 361 and 363 devices. With async suspend disabled, we always power on function 0 before function 1. Barto then reported the same problem with a JMicron 368 (see comment #57 in the bugzilla). Rather than extending the blacklist piecemeal, disable async suspend for all JMicron multi-function SATA/PATA/AHCI devices. This quirk could stay in the ahci and pata_jmicron drivers, but it's likely the problem will occur even if pata_jmicron isn't loaded until after the suspend/resume. Making it a PCI quirk ensures that we'll preserve the power-on order even if the drivers aren't loaded.

ahci: clean up board IDs ahci over time has grown a number of board IDs and it's a bit of mess right now. Clean it up such that, * board_id_* now live in a separate enum board_ids and numbers are assigned automatically. * Board IDs assigned to features are separated from the ones assigned to specific implementations and both are ordered alphabetically. * For NV MCPs, define per-generation alias board_ids and assign matching aliases in the pci id table. This makes mcp_linux, 67-73 use board_ahci_mcp65 instead of board_ahci_yesncq. Both are identical in content. * Kill now unused board_ahci_nopmp and board_ahci_yesncq. This patch doesn't cause any functional change but will make future changes to board_ids and quirks much less painful.

/* SiS */
ahci: sis controllers actually can do PMP SIS controllers were blacklisted for PMP as enabling it made device detection fail whether the device was PMP or not - the natural conclusion was the controller chokes on SRST w/ pmp==15. However, it turned out that the controller just didn't like issuing SRST after hardreset w/o clearing SError first. Interestingly, the SRST itself succeeds but the following commands fail. If SError is cleared between hardreset and SRST, which is the default behavior now, everything works fine and SIS controllers work with PMPs happily. Remove PMP blacklisting for SIS AHCIs.

Although this controller also supports SAS devices, its default bootup mode is AHCI and the binary driver has to do some magic to get the chip into the appropriate mode to drive SAS disks. Seeing as no documentation is provided by Promise, adding this entry to the ahci driver allows the controller to be useful to people as a SATA controller (with no ill effects on the system if a SAS disk is connected - probing of the port just times out with "link online but device misclassified"), without having to resort to using the binary driver.

[PATCH] ahci: convert to new EH Convert AHCI to new EH. Unfortunately, ICH7 AHCI reacts badly if IRQ mask is diddled during operation. So, freezing is implemented by unconditionally clearing interrupt conditions while frozen. * Interrupts are categorized according to required action. e.g. Connection status or unknown FIS error requires freezing the port while TF or HBUS_DATA don't. * Only CONNECT (reflects SErr.X) interrupt is taken into account not PHYRDY (SErr.N), as CONNECT is better cue for starting EH. * AHCI may be invoked without any active command. e.g. CONNECT irq occuring while no qc in progress still triggers EH and will reset the port and revalidate attached device.

ahci: ahci: implement workaround for ASUS P5W-DH Deluxe ahci_broken_hardreset(), take #2 P5W-DH Deluxe has ICH9 which doesn't have PMP support but SIMG 4726 hardwired to the second port of AHCI controller at PCI device 1f.2. The 4726 doesn't work as PMP but as a storage processor which can do hardware RAID on downstream ports. When no device is attached to the downstream port of the 4726, pseudo ATA device for configuration appears. Unfortunately, ATA emulation on the device is very lousy and causes long hang during boot. This patch implements workaround for the board. If the mainboard is P5W-DH Deluxe (matched using DMI), only hardreset is used on the second port of AHCI controller @ 1f.2 and the hardreset doesn't depend on receiving the first FIS and just proceed to IDENTIFY. This workaround fixes bugzilla #8923. http://bugzilla.kernel.org/show_bug.cgi?id=8923 Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

ahci: Add runtime PM support for the host controller This patch adds runtime PM support for the AHCI host controller driver so that the host controller is powered down when all SATA ports are runtime suspended. Powering down the AHCI host controller can reduce power consumption and possibly allow the CPU to enter lower power idle states (S0ix) during runtime. Runtime PM is blocked by default and needs to be unblocked from userspace as needed (via power/* sysfs nodes).

We're going to teach AHCI to work with non-PCI buses, so there are two options to make this work: 1. "fake" host->iomap array for non-PCI devices, and place the needed address at iomap[AHCI_PCI_BAR]; 2. Get rid of host->iomap usage, instead introduce a private mmio field. This patch implements the second option. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

ahci: Add runtime PM support for the host controller This patch adds runtime PM support for the AHCI host controller driver so that the host controller is powered down when all SATA ports are runtime suspended. Powering down the AHCI host controller can reduce power consumption and possibly allow the CPU to enter lower power idle states (S0ix) during runtime. Runtime PM is blocked by default and needs to be unblocked from userspace as needed (via power/* sysfs nodes).

Now that host and ap are available during intialization, functions are converted to take either host or ap instead of low level parameters which were inevitable for functions shared between init and other paths. This simplifies code quite a bit. * init_one()'s now follow more consistent init order * ahci_setup_port() and ahci_host_init() collapsed into ahci_init_one() for init order consistency * sata_vsc uses port_info instead of setting fields manually * in sata_svw, k2_board_info converted to port_info (info is now in port flags). port number is honored now.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

/* On ASUS P5W DH Deluxe, the second port of PCI device 00:1f.2 is
* hardwired to on-board SIMG 4726. The chipset is ICH8 and doesn't
* support PMP and the 4726 either directly exports the device
* attached to the first downstream port or acts as a hardware storage
* controller and emulate a single ATA device (can be RAID 0/1 or some
* other configuration).
*
* When there's no device attached to the first downstream port of the
* 4726, "Config Disk" appears, which is a pseudo ATA device to
* configure the 4726. However, ATA emulation of the device is very
* lame. It doesn't send signature D2H Reg FIS after the initial
* hardreset, pukes on SRST w/ PMP==0 and has bunch of other issues.
*
* The following function works around the problem by always using
* hardreset on the port and not depending on receiving signature FIS
* afterward. If signature FIS isn't received soon, ATA class is
* assumed without follow-up softreset.

SATA AHCI: Blacklist system that spins off disks during ACPI power off Some notebooks from HP have the problem that their BIOSes attempt to spin down hard drives before entering ACPI system states S4 and S5. This leads to a yo-yo effect during system power-off shutdown and the last phase of hibernation when the disk is first spun down by the kernel and then almost immediately turned on and off by the BIOS.

ahci: add workaround for on-board 5723s on some gigabyte boards Some gigabytes have on-board SIMG5723s connected to JMB ahcis. These are used to implement hardware raid. Unfortunately some firmware revisions on these 5723s don't bring the link down when all the downstream ports are unoccupied while not responding to reset protocol which makes libata think that there's device attached to the port but is not responding and retry. This results in painfully wrong boot detection time for these ports when they're empty. This patch quirks those boards such that ahci gives up after the initial timeout. Combined with parallel probing, this gives quick enough probing and also is safe because SIMG5723 will respond to the first try if any of the downstream ports is occupied.

ahci: disable DEVSLP for Intel Valleyview On Intel Valleyview SoC, SATA device sleep is not reliable. When DEVSLP is attempted on certain SSDs, port_devslp write would fail and result in malfunction of AHCI controller. AHCI controller may be not shown in PCI enumeration after reset. Complete power source removal may be required to recover from this failure. So we blacklist this device and override host device reported capabilities such that device LPM will only attempt slumber but not DEVSLP.

MSI-X support is needed for host controller that only have MSI-X support implemented, but no MSI or intx. This patch only adds support for single interrupts, multiple per-port MSI-X interrupts are not yet implemented. The new implementation still initializes MSIs first. Only if that fails, the code tries to enable MSI-X. If that fails too, setup is continued with intx interrupts. To not break other chips by this generic code change, there are the following precautions: * Interrupt ranges are not enabled at all. * Only single interrupt mode is enabled for msix cap devices. Thus, only one interrupt will be setup. * During the discussion with Tejun we agreed to change the init sequence from msix-msi-intx to msi-msix-intx. Thus, if a device offers msi and init does not fail, the msix init code will not be executed. This is equivalent to current code. With this, the code only setups single mode msix as a last resort if msi fails. No interrupt range is enabled at all. Only one interrupt will be enabled. tj: comment edits. Changes of the patch series: v5: * updated patch subject that the patch only implements single IRQ * moved Cavium specific code to a separate patch * detect Cavium ThunderX device with PCI_CLASS_STORAGE_SATA_AHCI instead of vendor/dev id * added more comments to the code * enable single msix support for all kind of devices (removing strict check) * rebased onto update libata/for-4.2 with patch 1, 2 applied v4: * removed implementation of ahci_init_intx() * improved patch descriptions * rebased onto libata/for-4.2 v3: * store irq number in struct ahci_host_priv * change initialization order from msix-msi-intx to msi-msix-intx * improve comments in ahci_init_msix() * improve error message in ahci_init_msix() * do not enable MSI-X if MSI is actively disabled for the device v2: * determine irq vector from pci_dev->msi_list Based on a patch from Sunil Goutham <sgoutham@cavium.com>.

MSI-X support is needed for host controller that only have MSI-X support implemented, but no MSI or intx. This patch only adds support for single interrupts, multiple per-port MSI-X interrupts are not yet implemented. The new implementation still initializes MSIs first.

To not break other chips by this generic code change, there are the following precautions: * Interrupt ranges are not enabled at all. * Only single interrupt mode is enabled for msix cap devices.

AHCI: Support multiple MSIs Take advantage of multiple MSIs implementation on x86 - on systems with IRQ remapping AHCI ports not only get assigned separate MSI vectors - but also separate IRQs. As result, interrupts generated by different ports could be serviced on different CPUs rather than on a single one. In cases when number of allocated MSIs is less than requested the Sharing Last MSI mode does not get used, no matter implemented in hardware or not. Instead, the driver assumes the advantage of multiple MSIs is negated and falls back to the single MSI mode as if MRSM bit was set (some Intel chips implement this strategy anyway - MRSM bit gets set even if the number of allocated MSIs exceeds the number of implemented ports).

ahci: Ensure "MSI Revert to Single Message" mode is not enforced The AHCI specification allows hardware to choose to revert to single MSI mode when fewer messages are allocated than requested. Yet, at least ICH10 chipset reverts to single MSI mode even when enough messages are allocated in some cases (see below). This update forces the driver to not rely on initialization of multiple MSIs mode alone and always check if "MSI Revert to Single Message" (MRSM) mode was enforced by the controller and fallback to the single MSI mode in case it did. That prevents a situation when the driver configured multiple per-port IRQ handlers, but the controller sends all port's interrupts to a single IRQ, which could easily screw up the interrupt handling and lead to delays and possibly crashes. The fix was tested on a 6-port controller that successfully reverted to the single MSI mode: 00:1f.2 SATA controller: Intel Corporation 82801JI (ICH10 Family) SATA AHCI Controller (prog-if 01 [AHCI 1.0]) Subsystem: Super Micro Computer Inc Device 10a7 Flags: bus master, 66MHz, medium devsel, latency 0, IRQ 101 I/O ports at f110 [size=8] I/O ports at f100 [size=4] I/O ports at f0f0 [size=8] I/O ports at f0e0 [size=4] I/O ports at f020 [size=32] Memory at fbf00000 (32-bit, non-prefetchable) [size=2K] Capabilities: [80] MSI: Enable+ Count=1/16 Maskable- 64bit- Capabilities: [70] Power Management version 3 Capabilities: [a8] SATA HBA v1.0 Capabilities: [b0] PCI Advanced Features Kernel driver in use: ahci With 6 ports just 8 MSI vectors should be enough, but the adapter enforces the MRSM mode when less than 16 vectors are written to the Multiple Messages Enable PCI register.

ahci: Add generic MSI-X support for single interrupts to SATA PCI driver This patch adds generic MSI-X support for single interrupts to the SATA PCI driver. MSI-X support is needed for host controller that only have MSI-X support implemented, but no MSI or intx. This patch only adds support for single interrupts, multiple per-port MSI-X interrupts are not yet implemented. The new implementation still initializes MSIs first. Only if that fails, the code tries to enable MSI-X. If that fails too, setup is continued with intx interrupts. To not break other chips by this generic code change, there are the following precautions: * Interrupt ranges are not enabled at all. * Only single interrupt mode is enabled for msix cap devices. Thus, only one interrupt will be setup. * During the discussion with Tejun we agreed to change the init sequence from msix-msi-intx to msi-msix-intx. Thus, if a device offers msi and init does not fail, the msix init code will not be executed. This is equivalent to current code. With this, the code only setups single mode msix as a last resort if msi fails. No interrupt range is enabled at all. Only one interrupt will be enabled. tj: comment edits. Changes of the patch series: v5: * updated patch subject that the patch only implements single IRQ * moved Cavium specific code to a separate patch * detect Cavium ThunderX device with PCI_CLASS_STORAGE_SATA_AHCI instead of vendor/dev id * added more comments to the code * enable single msix support for all kind of devices (removing strict check) * rebased onto update libata/for-4.2 with patch 1, 2 applied v4: * removed implementation of ahci_init_intx() * improved patch descriptions * rebased onto libata/for-4.2 v3: * store irq number in struct ahci_host_priv * change initialization order from msix-msi-intx to msi-msix-intx * improve comments in ahci_init_msix() * improve error message in ahci_init_msix() * do not enable MSI-X if MSI is actively disabled for the device v2: * determine irq vector from pci_dev->msi_list Based on a patch from Sunil Goutham <sgoutham@cavium.com>.

libata: update libata LLDs to use devres Update libata LLDs to use devres. Core layer is already converted to support managed LLDs. This patch simplifies initialization and fixes many resource related bugs in init failure and detach path. For example, all converted drivers now handle ata_device_add() failure gracefully without excessive resource rollback code. As most resources are released automatically on driver detach, many drivers don't need or can do with much simpler ->{port|host}_stop(). In general, stop callbacks are need iff port or host needs to be given commands to shut it down. Note that freezing is enough in many cases and ports are automatically frozen before being detached.

ahci, pata_marvell: play nicely together I've been chasing Jeff about this for months. Jeff added the Marvell device identifiers to the ahci driver without making the AHCI driver handle the PATA port. This means a lot of users can't use current kernels and in most distro cases can't even install. This has been going on since March 2008 for the 6121 Marvell, and late 2007 for the 6145!!! This was all pointed out at the time and repeatedly ignored. Bugs assigned to Jeff about this are ignored also. To quote Jeff in email > "Just switch the order of 'ahci' and 'pata_marvell' in > /etc/modprobe.conf, then use Fedora's tools regenerate the initrd. > See? It's not rocket science, and the current configuration can be > easily made to work for Fedora users." (Which isn't trivial, isn't end user, shouldn't be needed, and as it usually breaks at install time is in fact impossible) To quote Jeff in August 2007 > " mv-ahci-pata > Marvell 6121/6141 PATA support. Needs fixing in the 'PATA controller > command' area before it is usable, and can go upstream." Only he add the ids anyway later and caused regressions, adding a further id in March causing more regresions. The actual fix for the moment is very simple. If the user has included the pata_marvell driver let it drive the ports. If they've only selected for SATA support give them the AHCI driver which will run the port a fraction faster. Allow the user to control this decision via ahci.marvell_enable as a module parameter so that distributions can ship 'it works' defaults and smarter users (or config tools) can then flip it over it desired.

[libata] ahci: Withdraw IGN_SERR_INTERNAL for SB800 SATA There is an issue in ATI SB600/SB700 SATA that PxSERR.E should not be set on some conditions, which will lead to many SATA ODD error messages. commit 55a61604cd1354e1783364e1c901034f2f474b7d is the workaround.

SATA AHCI: Blacklist system that spins off disks during ACPI power off Some notebooks from HP have the problem that their BIOSes attempt to spin down hard drives before entering ACPI system states S4 and S5. This leads to a yo-yo effect during system power-off shutdown and the last phase of hibernation when the disk is first spun down by the kernel and then almost immediately turned on and off by the BIOS. This, in turn, may result in shortening the disk's life times. To prevent this from happening we can blacklist the affected systems using DMI information.

ahci: add workaround for on-board 5723s on some gigabyte boards Some gigabytes have on-board SIMG5723s connected to JMB ahcis. These are used to implement hardware raid. Unfortunately some firmware revisions on these 5723s don't bring the link down when all the downstream ports are unoccupied while not responding to reset protocol which makes libata think that there's device attached to the port but is not responding and retry. This results in painfully wrong boot detection time for these ports when they're empty. This patch quirks those boards such that ahci gives up after the initial timeout. Combined with parallel probing, this gives quick enough probing and also is safe because SIMG5723 will respond to the first try if any of the downstream ports is occupied.

ahci: fix CAP.NP and PI handling AHCI uses CAP.NP to indicate the number of ports and PI to tell which ports are enabled. The only requirement is that the number of ports indicated by CAP.NP should equal or be higher than the number of enabled ports in PI. CAP.NP and PI carry duplicate information and there have been some interesting cases. Some early AHCI controllers didn't set PI at all and just implement from port 0 to CAP.NP. An ICH8 board which wired four out of six available ports had 3 (4 ports) for CAP.NP and 0x33 for PI. While ESB2 has less bits set in PI than the value in CAP.NP. Till now, ahci driver assumed that PI is invalid if it doesn't match CAP.NP exactly. This violates AHCI standard and the driver ends up accessing unmimplemented ports on ESB2. This patch updates CAP.NP and PI handling such that PI can have less number of bits set than indicated in CAP.NP and the highest port is determined as the maximum port of what CAP.NP and PI indicate.

ahci: per-port msix support Some AHCI controllers support per-port MSI-X vectors. At the same time the Linux AHCI driver needs to support one-off architectures that implement a single MSI-X vector for all ports. The heuristic for enabling AHCI ports becomes, in order of preference: 1/ per-port multi-MSI-X 2/ per-port multi-MSI 3/ single MSI 4/ single MSI-X 5/ legacy INTX This all depends on AHCI implementations with potentially broken MSI-X requesting less vectors than the number of ports. If this assumption is violated we will need to start explicitly white-listing AHCI-MSIX implementations.

This allows the host controller to be activated in a generic way. This change is only intended for ahci drivers. For that reason the irq number is stored in struct ahci_host_priv used only by ahci drivers. Thus, the ABI changes only for ahci_host_activate(), but existing ata drivers (about 50) are unaffected and keep unchanged. All users of ahci_host_activate() have been updated.

ahci: add a module parameter to ignore the SSS flags for async scanning The SSS flag, which directs the OS to spin up one disk at a time to not have the PSU blow out, sometimes gets set even when not needed. The effect of this is a longer-than-needed boot time. This patch adds a module parameter that makes the driver ignore SSS at least as far as the parallel scan during boot is concerned...

libata: implement and use ata_port_desc() to report port configuration Currently, port configuration reporting has the following problems. * iomapped address is reported instead of raw address * report contains irrelevant fields or lacks necessary fields for non-SFF controllers. * host->irq/irq2 are there just for reporting and hacky. This patch implements and uses ata_port_desc() and ata_port_pbar_desc(). ata_port_desc() is almost identical to ata_ehi_push_desc() except that it takes @ap instead of @ehi, has no locking requirement, can only be used during host initialization and " " is used as separator instead of ", ". ata_port_pbar_desc() is a helper to ease reporting of a PCI BAR or an offsetted address into it. LLD pushes whatever description it wants using the above two functions. The accumulated description is printed on host registration after "[S/P]ATA max MAX_XFERMODE ". SFF init helpers and ata_host_activate() automatically add descriptions for addresses and irq respectively, so only LLDs which isn't standard SFF need to add custom descriptions. In many cases, such controllers need to report different things anyway. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

ahci: implement ata_save/restore_initial_config() There are several registers which describe how the controller is configured. These registers are sometimes implemented as r/w registers which are configured by firmware and get cleared on controller reset or after suspend/resume cycle. ahci saved and restored those values inside ahci_reset_controller() which is a bit messy and doesn't work over suspend/resume cycle. This patch implements ahci_save/restore_initial_config(). The save function is called during driver initialization and saves cap and port_map to hpriv. The restore function is called after the controller is reset to restore the initial values. Sometimes the initial firmware values are inconsistent and need to be fixed up. This is handled by ahci_save_initial_config(). For this, there are two versions of saved registers. One to write back to the hardware register, the other to use during driver operation. This is necessary to keep ahci's behavior unchanged (write back fixed up port_map while keeping cap as-is). This patch makes ahci save the register values once before the first controller reset, not after it's been reset. Also, the same stored values are used written back after each reset, so the register values are properly recovered after suspend/resume cycle.

ahci: ahci: implement workaround for ASUS P5W-DH Deluxe ahci_broken_hardreset(), take #2 P5W-DH Deluxe has ICH9 which doesn't have PMP support but SIMG 4726 hardwired to the second port of AHCI controller at PCI device 1f.2. The 4726 doesn't work as PMP but as a storage processor which can do hardware RAID on downstream ports. When no device is attached to the downstream port of the 4726, pseudo ATA device for configuration appears. Unfortunately, ATA emulation on the device is very lousy and causes long hang during boot. This patch implements workaround for the board. If the mainboard is P5W-DH Deluxe (matched using DMI), only hardreset is used on the second port of AHCI controller @ 1f.2 and the hardreset doesn't depend on receiving the first FIS and just proceed to IDENTIFY.

ahci: filter FPDMA non-zero offset enable for Aspire 3810T Curiously, Aspire 3810T issues many SATA feature enable commands via _GTF, of which one is invalid and another is not supported by the drive. In the process, it also enables FPDMA non-zero offset. However, the feature also needs to be supported and enabled from the controller and it's wrong to enable it from _GTF unless the controller can do it by default. Currently, this ends up enabling FPDMA non-zero offset only on the drive side leading to NCQ command failures and eventual disabling of NCQ. This patch makes libata filter out FPDMA non-zero offset enable for the machine.

This patch simplifies initialization and fixes many resource related bugs in init failure and detach path. For example, all converted drivers now handle ata_device_add() failure gracefully without excessive resource rollback code. As most resources are released automatically on driver detach, many drivers don't need or can do with much simpler ->{port|host}_stop(). In general, stop callbacks are need iff port or host needs to be given commands to shut it down. Note that freezing is enough in many cases and ports are automatically frozen before being detached.

AHCI: Support multiple MSIs Take advantage of multiple MSIs implementation on x86 - on systems with IRQ remapping AHCI ports not only get assigned separate MSI vectors - but also separate IRQs. As result, interrupts generated by different ports could be serviced on different CPUs rather than on a single one. In cases when number of allocated MSIs is less than requested the Sharing Last MSI mode does not get used, no matter implemented in hardware or not. Instead, the driver assumes the advantage of multiple MSIs is negated and falls back to the single MSI mode as if MRSM bit was set (some Intel chips implement this strategy anyway - MRSM bit gets set even if the number of allocated MSIs exceeds the number of implemented ports).
