AACRAID Driver for Linux (take two)
|
||||
|
||||
Introduction
|
||||
-------------------------
|
||||
The aacraid driver adds support for Adaptec (http://www.adaptec.com)
|
||||
RAID controllers. This is a major rewrite from the original
|
||||
Adaptec supplied driver. It has signficantly cleaned up both the code
|
||||
and the running binary size (the module is less than half the size of
|
||||
the original).

spi_butterfly - parport-to-butterfly adapter driver
|
||||
===================================================
|
||||
|
||||
This is a hardware and software project that includes building and using
|
||||
a parallel port adapter cable, together with an "AVR Butterfly" to run
|
||||
firmware for user interfacing and/or sensors. A Butterfly is a $US20
|
||||
battery powered card with an AVR microcontroller and lots of goodies:
|
||||
sensors, LCD, flash, toggle stick, and more. You can use AVR-GCC to
|
||||
develop firmware for this, and flash it using this adapter cable.
|
||||
|
||||
You can make this adapter from an old printer cable and solder things
|
||||
directly to the Butterfly. Or (if you have the parts and skills) you
|
||||
can come up with something fancier, providing ciruit protection to the
|
||||
Butterfly and the printer port, or with a better power supply than two
|
||||
signal pins from the printer port.
|
||||
|
||||
|
||||
The first cable connections will hook Linux up to one SPI bus, with the
|
||||
AVR and a DataFlash chip; and to the AVR reset line. This is all you
|
||||
need to reflash the firmware, and the pins are the standard Atmel "ISP"
|
||||
connector pins (used also on non-Butterfly AVR boards).
|
||||
|
||||
Signal Butterfly Parport (DB-25)
|
||||
------ --------- ---------------
|
||||
SCK = J403.PB1/SCK = pin 2/D0
|
||||
RESET = J403.nRST = pin 3/D1
|
||||
VCC = J403.VCC_EXT = pin 8/D6
|
||||
MOSI = J403.PB2/MOSI = pin 9/D7
|
||||
MISO = J403.PB3/MISO = pin 11/S7,nBUSY
|
||||
GND = J403.GND = pin 23/GND
|
||||
|
||||
Then to let Linux master that bus to talk to the DataFlash chip, you must
|
||||
(a) flash new firmware that disables SPI (set PRR.2, and disable pullups
|
||||
by clearing PORTB.[0-3]); (b) configure the mtd_dataflash driver; and
|
||||
(c) cable in the chipselect.
|
||||
|
||||
Signal Butterfly Parport (DB-25)
|
||||
------ --------- ---------------
|
||||
VCC = J400.VCC_EXT = pin 7/D5
|
||||
SELECT = J400.PB0/nSS = pin 17/C3,nSELECT
|
||||
GND = J400.GND = pin 24/GND
|
||||
|
||||
The "USI" controller, using J405, can be used for a second SPI bus. That
|
||||
would let you talk to the AVR over SPI, running firmware that makes it act
|
||||
as an SPI slave, while letting either Linux or the AVR use the DataFlash.
|
||||
There are plenty of spare parport pins to wire this one up, such as:

Overview of Linux kernel SPI support
|
||||
====================================
|
||||
|
||||
02-Dec-2005
|
||||
|
||||
What is SPI?
|
||||
------------
|
||||
The "Serial Peripheral Interface" (SPI) is a synchronous four wire serial
|
||||
link used to connect microcontrollers to sensors, memory, and peripherals.
|
||||
|
||||
The three signal wires hold a clock (SCLK, often on the order of 10 MHz),
|
||||
and parallel data lines with "Master Out, Slave In" (MOSI) or "Master In,
|
||||
Slave Out" (MISO) signals. (Other names are also used.) There are four
|
||||
clocking modes through which data is exchanged; mode-0 and mode-3 are most
|
||||
commonly used. Each clock cycle shifts data out and data in; the clock
|
||||
doesn't cycle except when there is data to shift.
|
||||
|
||||
SPI masters may use a "chip select" line to activate a given SPI slave
|
||||
device, so those three signal wires may be connected to several chips
|
||||
in parallel. All SPI slaves support chipselects. Some devices have
|
||||
other signals, often including an interrupt to the master.
|
||||
|
||||
Unlike serial busses like USB or SMBUS, even low level protocols for
|
||||
SPI slave functions are usually not interoperable between vendors
|
||||
(except for cases like SPI memory chips).
|
||||
|
||||
- SPI may be used for request/response style device protocols, as with
|
||||
touchscreen sensors and memory chips.
|
||||
|
||||
- It may also be used to stream data in either direction (half duplex),
|
||||
or both of them at the same time (full duplex).
|
||||
|
||||
- Some devices may use eight bit words. Others may different word
|
||||
lengths, such as streams of 12-bit or 20-bit digital samples.
|
||||
|
||||
In the same way, SPI slaves will only rarely support any kind of automatic
|
||||
discovery/enumeration protocol. The tree of slave devices accessible from
|
||||
a given SPI master will normally be set up manually, with configuration
|
||||
tables.
|
||||
|
||||
SPI is only one of the names used by such four-wire protocols, and
|
||||
most controllers have no problem handling "MicroWire" (think of it as
|
||||
half-duplex SPI, for request/response protocols), SSP ("Synchronous
|
||||
Serial Protocol"), PSP ("Programmable Serial Protocol"), and other
|
||||
related protocols.
|
||||
|
||||
Microcontrollers often support both master and slave sides of the SPI
|
||||
protocol. This document (and Linux) currently only supports the master
|
||||
side of SPI interactions.
|
||||
|
||||
|
||||
Who uses it? On what kinds of systems?
|
||||
---------------------------------------
|
||||
Linux developers using SPI are probably writing device drivers for embedded
|
||||
systems boards. SPI is used to control external chips, and it is also a
|
||||
protocol supported by every MMC or SD memory card. (The older "DataFlash"
|
||||
cards, predating MMC cards but using the same connectors and card shape,
|
||||
support only SPI.) Some PC hardware uses SPI flash for BIOS code.
|
||||
|
||||
SPI slave chips range from digital/analog converters used for analog
|
||||
sensors and codecs, to memory, to peripherals like USB controllers
|
||||
or Ethernet adapters; and more.
|
||||
|
||||
Most systems using SPI will integrate a few devices on a mainboard.
|
||||
Some provide SPI links on expansion connectors; in cases where no
|
||||
dedicated SPI controller exists, GPIO pins can be used to create a
|
||||
low speed "bitbanging" adapter. Very few systems will "hotplug" an SPI
|
||||
controller; the reasons to use SPI focus on low cost and simple operation,
|
||||
and if dynamic reconfiguration is important, USB will often be a more
|
||||
appropriate low-pincount peripheral bus.
|
||||
|
||||
Many microcontrollers that can run Linux integrate one or more I/O
|
||||
interfaces with SPI modes. Given SPI support, they could use MMC or SD
|
||||
cards without needing a special purpose MMC/SD/SDIO controller.
|
||||
|
||||
|
||||
How do these driver programming interfaces work?
|
||||
------------------------------------------------
|
||||
The <linux/spi/spi.h> header file includes kerneldoc, as does the
|
||||
main source code, and you should certainly read that. This is just
|
||||
an overview, so you get the big picture before the details.
|
||||
|
||||
SPI requests always go into I/O queues. Requests for a given SPI device
|
||||
are always executed in FIFO order, and complete asynchronously through
|
||||
completion callbacks. There are also some simple synchronous wrappers
|
||||
for those calls, including ones for common transaction types like writing
|
||||
a command and then reading its response.
|
||||
|
||||
There are two types of SPI driver, here called:
|
||||
|
||||
Controller drivers ... these are often built in to System-On-Chip
|
||||
processors, and often support both Master and Slave roles.
|
||||
These drivers touch hardware registers and may use DMA.
|
||||
Or they can be PIO bitbangers, needing just GPIO pins.
|
||||
|
||||
Protocol drivers ... these pass messages through the controller
|
||||
driver to communicate with a Slave or Master device on the
|
||||
other side of an SPI link.
|
||||
|
||||
So for example one protocol driver might talk to the MTD layer to export
|
||||
data to filesystems stored on SPI flash like DataFlash; and others might
|
||||
control audio interfaces, present touchscreen sensors as input interfaces,
|
||||
or monitor temperature and voltage levels during industrial processing.
|
||||
And those might all be sharing the same controller driver.
|
||||
|
||||
A "struct spi_device" encapsulates the master-side interface between
|
||||
those two types of driver. At this writing, Linux has no slave side
|
||||
programming interface.
|
||||
|
||||
There is a minimal core of SPI programming interfaces, focussing on
|
||||
using driver model to connect controller and protocol drivers using
|
||||
device tables provided by board specific initialization code. SPI
|
||||
shows up in sysfs in several locations:
|
||||
|
||||
/sys/devices/.../CTLR/spiB.C ... spi_device for on bus "B",
|
||||
chipselect C, accessed through CTLR.
|
||||
|
||||
/sys/devices/.../CTLR/spiB.C/modalias ... identifies the driver
|
||||
that should be used with this device (for hotplug/coldplug)
|
||||
|
||||
/sys/bus/spi/devices/spiB.C ... symlink to the physical
|
||||
spiB-C device
|
||||
|
||||
/sys/bus/spi/drivers/D ... driver for one or more spi*.* devices
|
||||
|
||||
/sys/class/spi_master/spiB ... class device for the controller
|
||||
managing bus "B". All the spiB.* devices share the same
|
||||
physical SPI bus segment, with SCLK, MOSI, and MISO.
|
||||
|
||||
|
||||
How does board-specific init code declare SPI devices?
|
||||
------------------------------------------------------
|
||||
Linux needs several kinds of information to properly configure SPI devices.
|
||||
That information is normally provided by board-specific code, even for
|
||||
chips that do support some of automated discovery/enumeration.
|
||||
|
||||
DECLARE CONTROLLERS
|
||||
|
||||
The first kind of information is a list of what SPI controllers exist.
|
||||
For System-on-Chip (SOC) based boards, these will usually be platform
|
||||
devices, and the controller may need some platform_data in order to
|
||||
operate properly. The "struct platform_device" will include resources
|
||||
like the physical address of the controller's first register and its IRQ.
|
||||
|
||||
Platforms will often abstract the "register SPI controller" operation,
|
||||
maybe coupling it with code to initialize pin configurations, so that
|
||||
the arch/.../mach-*/board-*.c files for several boards can all share the
|
||||
same basic controller setup code. This is because most SOCs have several
|
||||
SPI-capable controllers, and only the ones actually usable on a given
|
||||
board should normally be set up and registered.
|
||||
|
||||
So for example arch/.../mach-*/board-*.c files might have code like:
|
||||
|
||||
#include <asm/arch/spi.h> /* for mysoc_spi_data */
|
||||
|
||||
/* if your mach-* infrastructure doesn't support kernels that can
|
||||
* run on multiple boards, pdata wouldn't benefit from "__init".
|
||||
*/
|
||||
static struct mysoc_spi_data __init pdata = { ... };
|
||||
|
||||
static __init board_init(void)
|
||||
{
|
||||
...
|
||||
/* this board only uses SPI controller #2 */
|
||||
mysoc_register_spi(2, &pdata);
|
||||
...
|
||||
}
|
||||
|
||||
And SOC-specific utility code might look something like:
|
||||
|
||||
#include <asm/arch/spi.h>
|
||||
|
||||
static struct platform_device spi2 = { ... };
|
||||
|
||||
void mysoc_register_spi(unsigned n, struct mysoc_spi_data *pdata)
|
||||
{
|
||||
struct mysoc_spi_data *pdata2;
|
||||
|
||||
pdata2 = kmalloc(sizeof *pdata2, GFP_KERNEL);
|
||||
*pdata2 = pdata;
|
||||
...
|
||||
if (n == 2) {
|
||||
spi2->dev.platform_data = pdata2;
|
||||
register_platform_device(&spi2);
|
||||
|
||||
/* also: set up pin modes so the spi2 signals are
|
||||
* visible on the relevant pins ... bootloaders on
|
||||
* production boards may already have done this, but
|
||||
* developer boards will often need Linux to do it.
|
||||
*/
|
||||
}
|
||||
...
|
||||
}
|
||||
|
||||
Notice how the platform_data for boards may be different, even if the
|
||||
same SOC controller is used. For example, on one board SPI might use
|
||||
an external clock, where another derives the SPI clock from current
|
||||
settings of some master clock.
|
||||
|
||||
|
||||
DECLARE SLAVE DEVICES
|
||||
|
||||
The second kind of information is a list of what SPI slave devices exist
|
||||
on the target board, often with some board-specific data needed for the
|
||||
driver to work correctly.
|
||||
|
||||
Normally your arch/.../mach-*/board-*.c files would provide a small table
|
||||
listing the SPI devices on each board. (This would typically be only a
|
||||
small handful.) That might look like:
|
||||
|
||||
static struct ads7846_platform_data ads_info = {
|
||||
.vref_delay_usecs = 100,
|
||||
.x_plate_ohms = 580,
|
||||
.y_plate_ohms = 410,
|
||||
};
|
||||
|
||||
static struct spi_board_info spi_board_info[] __initdata = {
|
||||
{
|
||||
.modalias = "ads7846",
|
||||
.platform_data = &ads_info,
|
||||
.mode = SPI_MODE_0,
|
||||
.irq = GPIO_IRQ(31),
|
||||
.max_speed_hz = 120000 /* max sample rate at 3V */ * 16,
|
||||
.bus_num = 1,
|
||||
.chip_select = 0,
|
||||
},
|
||||
};
|
||||
|
||||
Again, notice how board-specific information is provided; each chip may need
|
||||
several types. This example shows generic constraints like the fastest SPI
|
||||
clock to allow (a function of board voltage in this case) or how an IRQ pin
|
||||
is wired, plus chip-specific constraints like an important delay that's
|
||||
changed by the capacitance at one pin.
|
||||
|
||||
(There's also "controller_data", information that may be useful to the
|
||||
controller driver. An example would be peripheral-specific DMA tuning
|
||||
data or chipselect callbacks. This is stored in spi_device later.)
|
||||
|
||||
The board_info should provide enough information to let the system work
|
||||
without the chip's driver being loaded. The most troublesome aspect of
|
||||
that is likely the SPI_CS_HIGH bit in the spi_device.mode field, since
|
||||
sharing a bus with a device that interprets chipselect "backwards" is
|
||||
not possible.
|
||||
|
||||
Then your board initialization code would register that table with the SPI
|
||||
infrastructure, so that it's available later when the SPI master controller
|
||||
driver is registered:
|
||||
|
||||
spi_register_board_info(spi_board_info, ARRAY_SIZE(spi_board_info));
|
||||
|
||||
Like with other static board-specific setup, you won't unregister those.
|
||||
|
||||
The widely used "card" style computers bundle memory, cpu, and little else
|
||||
onto a card that's maybe just thirty square centimeters. On such systems,
|
||||
your arch/.../mach-.../board-*.c file would primarily provide information
|
||||
about the devices on the mainboard into which such a card is plugged. That
|
||||
certainly includes SPI devices hooked up through the card connectors!
|
||||
|
||||
|
||||
NON-STATIC CONFIGURATIONS
|
||||
|
||||
Developer boards often play by different rules than product boards, and one
|
||||
example is the potential need to hotplug SPI devices and/or controllers.
|
||||
|
||||
For those cases you might need to use use spi_busnum_to_master() to look
|
||||
up the spi bus master, and will likely need spi_new_device() to provide the
|
||||
board info based on the board that was hotplugged. Of course, you'd later
|
||||
call at least spi_unregister_device() when that board is removed.
|
||||
|
||||
When Linux includes support for MMC/SD/SDIO/DataFlash cards through SPI, those
|
||||
configurations will also be dynamic. Fortunately, those devices all support
|
||||
basic device identification probes, so that support should hotplug normally.
|
||||
|
||||
|
||||
How do I write an "SPI Protocol Driver"?
|
||||
----------------------------------------
|
||||
All SPI drivers are currently kernel drivers. A userspace driver API
|
||||
would just be another kernel driver, probably offering some lowlevel
|
||||
access through aio_read(), aio_write(), and ioctl() calls and using the
|
||||
standard userspace sysfs mechanisms to bind to a given SPI device.
|
||||
|
||||
SPI protocol drivers somewhat resemble platform device drivers:
|
||||
|
||||
static struct spi_driver CHIP_driver = {
|
||||
.driver = {
|
||||
.name = "CHIP",
|
||||
.bus = &spi_bus_type,
|
||||
.owner = THIS_MODULE,
|
||||
},
|
||||
|
||||
.probe = CHIP_probe,
|
||||
.remove = __devexit_p(CHIP_remove),
|
||||
.suspend = CHIP_suspend,
|
||||
.resume = CHIP_resume,
|
||||
};
|
||||
|
||||
The driver core will autmatically attempt to bind this driver to any SPI
|
||||
device whose board_info gave a modalias of "CHIP". Your probe() code
|
||||
might look like this unless you're creating a class_device:
|
||||
|
||||
static int __devinit CHIP_probe(struct spi_device *spi)
|
||||
{
|
||||
struct CHIP *chip;
|
||||
struct CHIP_platform_data *pdata;
|
||||
|
||||
/* assuming the driver requires board-specific data: */
|
||||
pdata = &spi->dev.platform_data;
|
||||
if (!pdata)
|
||||
return -ENODEV;
|
||||
|
||||
/* get memory for driver's per-chip state */
|
||||
chip = kzalloc(sizeof *chip, GFP_KERNEL);
|
||||
if (!chip)
|
||||
return -ENOMEM;
|
||||
dev_set_drvdata(&spi->dev, chip);
|
||||
|
||||
... etc
|
||||
return 0;
|
||||
}
|
||||
|
||||
As soon as it enters probe(), the driver may issue I/O requests to
|
||||
the SPI device using "struct spi_message". When remove() returns,
|
||||
the driver guarantees that it won't submit any more such messages.
|
||||
|
||||
- An spi_message is a sequence of of protocol operations, executed
|
||||
as one atomic sequence. SPI driver controls include:
|
||||
|
||||
+ when bidirectional reads and writes start ... by how its
|
||||
sequence of spi_transfer requests is arranged;
|
||||
|
||||
+ optionally defining short delays after transfers ... using
|
||||
the spi_transfer.delay_usecs setting;
|
||||
|
||||
+ whether the chipselect becomes inactive after a transfer and
|
||||
any delay ... by using the spi_transfer.cs_change flag;
|
||||
|
||||
+ hinting whether the next message is likely to go to this same
|
||||
device ... using the spi_transfer.cs_change flag on the last
|
||||
transfer in that atomic group, and potentially saving costs
|
||||
for chip deselect and select operations.
|
||||
|
||||
- Follow standard kernel rules, and provide DMA-safe buffers in
|
||||
your messages. That way controller drivers using DMA aren't forced
|
||||
to make extra copies unless the hardware requires it (e.g. working
|
||||
around hardware errata that force the use of bounce buffering).
|
||||
|
||||
If standard dma_map_single() handling of these buffers is inappropriate,
|
||||
you can use spi_message.is_dma_mapped to tell the controller driver
|
||||
that you've already provided the relevant DMA addresses.
|
||||
|
||||
- The basic I/O primitive is spi_async(). Async requests may be
|
||||
issued in any context (irq handler, task, etc) and completion
|
||||
is reported using a callback provided with the message.
|
||||
After any detected error, the chip is deselected and processing
|
||||
of that spi_message is aborted.
|
||||
|
||||
- There are also synchronous wrappers like spi_sync(), and wrappers
|
||||
like spi_read(), spi_write(), and spi_write_then_read(). These
|
||||
may be issued only in contexts that may sleep, and they're all
|
||||
clean (and small, and "optional") layers over spi_async().
|
||||
|
||||
- The spi_write_then_read() call, and convenience wrappers around
|
||||
it, should only be used with small amounts of data where the
|
||||
cost of an extra copy may be ignored. It's designed to support
|
||||
common RPC-style requests, such as writing an eight bit command
|
||||
and reading a sixteen bit response -- spi_w8r16() being one its
|
||||
wrappers, doing exactly that.
|
||||
|
||||
Some drivers may need to modify spi_device characteristics like the
|
||||
transfer mode, wordsize, or clock rate. This is done with spi_setup(),
|
||||
which would normally be called from probe() before the first I/O is
|
||||
done to the device.
|
||||
|
||||
While "spi_device" would be the bottom boundary of the driver, the
|
||||
upper boundaries might include sysfs (especially for sensor readings),
|
||||
the input layer, ALSA, networking, MTD, the character device framework,
|
||||
or other Linux subsystems.
|
||||
|
||||
Note that there are two types of memory your driver must manage as part
|
||||
of interacting with SPI devices.
|
||||
|
||||
- I/O buffers use the usual Linux rules, and must be DMA-safe.
|
||||
You'd normally allocate them from the heap or free page pool.
|
||||
Don't use the stack, or anything that's declared "static".
|
||||
|
||||
- The spi_message and spi_transfer metadata used to glue those
|
||||
I/O buffers into a group of protocol transactions. These can
|
||||
be allocated anywhere it's convenient, including as part of
|
||||
other allocate-once driver data structures. Zero-init these.
|
||||
|
||||
If you like, spi_message_alloc() and spi_message_free() convenience
|
||||
routines are available to allocate and zero-initialize an spi_message
|
||||
with several transfers.
|
||||
|
||||
|
||||
How do I write an "SPI Master Controller Driver"?
|
||||
-------------------------------------------------
|
||||
An SPI controller will probably be registered on the platform_bus; write
|
||||
a driver to bind to the device, whichever bus is involved.
|
||||
|
||||
The main task of this type of driver is to provide an "spi_master".
|
||||
Use spi_alloc_master() to allocate the master, and class_get_devdata()
|
||||
to get the driver-private data allocated for that device.
|
||||
|
||||
struct spi_master *master;
|
||||
struct CONTROLLER *c;
|
||||
|
||||
master = spi_alloc_master(dev, sizeof *c);
|
||||
if (!master)
|
||||
return -ENODEV;
|
||||
|
||||
c = class_get_devdata(&master->cdev);
|
||||
|
||||
The driver will initialize the fields of that spi_master, including the
|
||||
bus number (maybe the same as the platform device ID) and three methods
|
||||
used to interact with the SPI core and SPI protocol drivers. It will
|
||||
also initialize its own internal state.
|
||||
|
||||
master->setup(struct spi_device *spi)
|
||||
This sets up the device clock rate, SPI mode, and word sizes.
|
||||
Drivers may change the defaults provided by board_info, and then
|
||||
call spi_setup(spi) to invoke this routine. It may sleep.
|
||||
|
||||
master->transfer(struct spi_device *spi, struct spi_message *message)
|
||||
This must not sleep. Its responsibility is arrange that the
|
||||
transfer happens and its complete() callback is issued; the two
|
||||
will normally happen later, after other transfers complete.
|
||||
|
||||
master->cleanup(struct spi_device *spi)
|
||||
Your controller driver may use spi_device.controller_state to hold
|
||||
state it dynamically associates with that device. If you do that,
|
||||
be sure to provide the cleanup() method to free that state.
|
||||
|
||||
The bulk of the driver will be managing the I/O queue fed by transfer().
|
||||
|
||||
That queue could be purely conceptual. For example, a driver used only
|
||||
for low-frequency sensor acess might be fine using synchronous PIO.
|
||||
|
||||
But the queue will probably be very real, using message->queue, PIO,
|
||||
often DMA (especially if the root filesystem is in SPI flash), and
|
||||
execution contexts like IRQ handlers, tasklets, or workqueues (such
|
||||
as keventd). Your driver can be as fancy, or as simple, as you need.

|
||||
space environment that is also compiled with EABI.
|
||||
|
||||
Since there are major incompatibilities between the legacy ABI and
|
||||
EABI, especially with regard to structure member alignment, this
|
||||
option also changes the kernel syscall calling convention to
|
||||
disambiguate both ABIs and allow for backward compatibility support
|
||||
(selected with CONFIG_OABI_COMPAT).
|
||||
|
||||
To use this you need GCC version 4.0.0 or later.

help
|
||||
This option preserves the old syscall interface along with the
|
||||
new (ARM EABI) one. It also provides a compatibility layer to
|
||||
intercept syscalls that have structure arguments which layout
|
||||
in memory differs between the legacy ABI and the new ARM EABI
|
||||
(only for non "thumb" binaries). This option adds a tiny
|
||||
overhead to all syscalls and produces a slightly larger kernel.
|
||||
If you know you'll be using only pure EABI user space then you
|
||||
can say N here. If this option is not selected and you attempt
|
||||
to execute a legacy ABI binary then the result will be
|
||||
UNPREDICTABLE (in fact it can be predicted that it won't work
|
||||
at all). If in doubt say Y.

|

/*
|
||||
* The legacy ABI and the new ARM EABI have different rules making some
|
||||
* syscalls incompatible especially with structure arguments.
|
||||
* Most notably, Eabi says 64-bit members should be 64-bit aligned instead of
|
||||
* simply word aligned. EABI also pads structures to the size of the largest
|
||||
* member it contains instead of the invariant 32-bit.
|
||||
*
|
||||
* The following syscalls are affected:
|
||||
*
|
||||
* sys_stat64:
|
||||
* sys_lstat64:
|
||||
* sys_fstat64:
|
||||
*
|
||||
* struct stat64 has different sizes and some members are shifted
|
||||
* Compatibility wrappers are needed for them and provided below.
|
||||
*
|
||||
* sys_fcntl64:
|
||||
*
|
||||
* struct flock64 has different sizes and some members are shifted
|
||||
* A compatibility wrapper is needed and provided below.
|
||||
*
|
||||
* sys_statfs64:
|
||||
* sys_fstatfs64:
|
||||
*
|
||||
* struct statfs64 has extra padding with EABI growing its size from
|
||||
* 84 to 88. This struct is now __attribute__((packed,aligned(4)))
|
||||
* with a small assembly wrapper to force the sz argument to 84 if it is 88
|
||||
* to avoid copying the extra padding over user space unexpecting it.
|
||||
*
|
||||
* sys_newuname:
|
||||
*
|
||||
* struct new_utsname has no padding with EABI. No problem there.
|
||||
*
|
||||
* sys_epoll_ctl:
|
||||
* sys_epoll_wait:
|
||||
*
|
||||
* struct epoll_event has its second member shifted also affecting the
|
||||
* structure size. Compatibility wrappers are needed and provided below.
|
||||
*
|
||||
* sys_ipc:
|
||||
* sys_semop:
|
||||
* sys_semtimedop:
|
||||
*
|
||||
* struct sembuf loses its padding with EABI. Since arrays of them are
|
||||
* used they have to be copyed to remove the padding. Compatibility wrappers
|
||||
