On particularly weak signals, changing register 0xab after setting the
interleave mode will cause the FEC lock to get lost (while still holding the
EQ lock). So remove the write entirely, which seems to have had no adverse
effect in either of my ClearQAM environments (and in particular resolves the
customer's reported issue).
Also flip around the order of the amhum optimization and the interleave setup
to be consistent with the windows driver, which has the side-benefit of doing
them both in the same call (since the amhum optimization can only be done once
the interleave setup).

The sh51409 driver was only doing the QAM optimization a single time, and it
would only occur if you received a lock instantaneously after the tuning
request. Restructure the code so that the optimization occurs once you reach
a signal lock.
Note that this depends on the caller polling for status, but we don't have
much choice at this point without an independent thread monitoring the lock
status. Also, at this point pretty much every application polls for status
lock after doing the tune, so the likelihood of the optimization not occurring
in the real world is pretty low.
The state machine has also been reworked such that setting the interleave mode
is now a dependency of doing the QAM optimization. Before both were mutually
exclusive, which was not consistent with the Windows driver. We now have a
single state machine that controls both.
The changes as-is are only enabled for the HVR-1600. Once the changes are
tested with some of the other boards, this change should be made generic and
the "_legacy" functions should be removed.

Upcoming I2C v4l2_subdev drivers need a way to control the subdevice
power state from the core. This use case is already partially covered by
the tuner s_standby operation, but no way to explicitly come back from
the standby state is available.
Rename the tuner s_standby operation to core s_power, and fix tuner
drivers accordingly. The tuner core will call s_power(0) instead of
s_standby(). No explicit call to s_power(1) is required for tuners as
they are supposed to wake up from standby automatically.

It used to be that the only real detectable reason for the driver to
fail during initialization would be that if the hardware is simply
jammed. However with the advent of the sub-device mechanism in V4L it
is possible now to detect if a sub-device module fails to load
successfully. The pvrusb2 driver does in fact react to this by also
(correctly) failing, however the original diagnostic message "hardware
is jammed" was still being reported. This misleads the user because
in fact it might not actually be a hardware failure. This change adds
logic to tell the difference and then report a more appropriate

gspca w9968cf: Add support for JPEG compression, this enables much higher
framerates at 320x240 / 352x288 and also allows for 640x480 mode for
cams which can do this. The w9968cf uses planar JPEG, which libv4l until
now did not support, so this requires atleast version 0.6.3 of libv4l.
And something important I forgot to mention in my earlier w9968cf commits:

This patch adds support to gspca for the Winbond W9967CF and W9968CF
camera's. This is mostly a port of the existing v4l1 driver to gspca
(making it v4l2). But this also features fixes to the bitbanging i2c code
(send a nack not an ack after reading the last byte of a transfer), which
gets rid of the weird errors which were being seen there, and of
the smbus_refresh() hack to get around these errors.
Also the vstart settings have been tweaked to work with different

If the I2C device provides an interrupt it is registered and the

is updated via interrupts rather than polling.

When the image size (bytesperline*height) is not multiple
of PAGE_SIZE, v4l2 rounded the required buffer size to
be multiple of PAGE_SIZE. This prevented user space
to store images directly into userptr buffers which were
not multiple of PAGE_SIZE. This constraint is removed.
The start address is still assumed to be required
page-aligned, ie., when v4l2 allocates mmap buffers,
the offset between different buffers is page-aligned.

1,If usb_buffer_alloc can't allocate a buffer sucessfully,
uvc_free_urb_buffers will be called to free the allocated
buffers, and stream->urb_size is required to be passed to
usb_buffer_free;
2,uvc_free_urb_buffers can reset stream->urb_size.

This adds an soc-camera / v4l2-subdev driver for the RJ54N1CB0C CMOS camera
sensor from Sharp. The sensor is very picky about initialisation and
configuration sequences. The driver limits artificially maximum window size by
800x600, although the sensor supports 1600x1200. Sizes above 800x600 don't seem
to work correctly, besides, examples from the system integrator use sizes above
640x480 only for still photography. Unfortunately, I had to use "magic"
register-value pairs for undocumented and "reserved" registers. This version of
the driver also omits some functionality, like cropping, which hasn't been
sufficiently tested yet and will be added later.

responding properly but all other registers returning the same value
(0x13 and 0x5 have been observed). This state will cause proper detection of
'885 vs. '887 vs. '888 to fail and the chip won't respond to get configured
properly anyway. I have no method of reseting the core to a working state at
this time; but I didn't try too hard to work one out either. The problem
likely only occurs in development. I suspect configuring the SYS PLL VCO to

IR controllers
2. possibly port it to the cx18 module for the CX23418 IR controller

The flag ZFCP_STATUS_FSFREQ_TMFUNCNOTSUPP is never set and hence can
be removed. This is a leftover from the time when zfcp had to decide
whether the target supports a "logical unit reset" or not. Nowadays,
the SCSI midlayer calls the eh_device_reset_handler or the
eh_target_reset_handler and zfcp simply maps this to a "logical unit
reset" or a "target reset".

In case the SCSI error recovery starts because of a SCSI command
timeout, but then something else triggers the rport to be deleted, the
SCSI error recovery will run to the end and set the SCSI device
offline. To prevent this, call the FC transport function
fc_block_scsi_eh which waits until the rport leaves the BLOCKED state.
This guarantees that communication is possible if the rport is ONLINE,
or the SCSI devices will be removed if the rport state switches to
NOT_PRESENT.

The SCSI midlayer retries commands based on the remote port state and

FSF errors back to the SCSI midlayer. See
http://marc.info/?l=linux-scsi&m=125668044215051&w=2 as reference.
There is also no need in special treatment of ABORTED commands, so
remove the ZFCP_STATUS_FSFREQ_ABORTED, the commands are then returned
with DID_TRANSPORT_DISRUPTED.
Also remove the ZFCP_STATUS_FSFREQ_RETRY: It is useless, no retry is

If an error occurs that triggers the call to fc_remote_port_delete,
ideally this call would happen before any I/O is passed back to the
SCSI midlayer through scsi_done. The SCSI midlayer will retry the
commands and fc_remote_port_chkready will return the correct status
code. But with the delay between calling scsi_done in softirq context
and the call to fc_remote_port_delete from the workqueue, there is a
window where zfcp returns DID_ERROR. This leads to SCSI error recovery
which then leads to offline SCSI devices since all recovery actions
will fail with the rport now being blocked.
In this window, zfcp has to return DID_IMM_RETRY just as the FC
transport class would do in fc_remote_port_chkready for the blocked
fc_rport. As soon as the fc_rport is BLOCKED, fc_remote_port_chkready
will do the right thing.
Additionally, there are two more cases to catch in zfcp_scsi_queuecommand:
- After the port has been opened, the unit has to be opened. During
this period I/O has to be retried. This can also be handled with
DID_IMM_RETRY.
- If the access to the unit fails, but the port is good, then
this single unit cannot be accessed and I/O to this unit has to fail
without involving the FC transport class.

Allow FCP frames to bypass the FCoE receive processing threads and handle
them directly in softirq context, if they are received on the correct CPU.
This preserves the queuing to threads for scaling out receive processing
to multiple CPUs, but allows FCoE-aware multi-queue network drivers that
direct frames to the originating CPUs to handle FCP processing with less
scheduling latency.
Only FCP is handled directly, because libfc makes use of mutexes in ELS
handling routines.
The bulk of this change is just moving the FCoE receive processing out of
the receive thread function, leaving behind just the thread and queue

Administer some love to the osd_req_decode_sense function
* Fix a bad bug with osd_req_decode_sense(). If there was no scsi
residual, .i.e the request never reached the target, then all the
osd_sense_info members where garbage.
* Add grossly missing in/out_resid to osd_sense_info and fill them in
properly.
* Define an osd_err_priority enum which divides the possible errors into
7 categories in ascending severity. Each category is also assigned a
Linux return code translation.
Analyze the different osd/scsi/block returned errors and set the
proper osd_err_priority and Linux return code accordingly.
* extra check a few situations so not to get stuck with inconsistent
error view. Example an empty residual with an error code, and other
places ...
Lots of libosd's osd_req_decode_sense clients had this logic in some
form or another. Consolidate all these into one place that should
actually know about osd returns. Thous translating it to a more

Define an osd_dev_info structure that Uniquely identifies an OSD
device lun on the network. The identification is built from unique
target attributes and is the same for all network/SAN machines.
osduld_info_lookup() - NEW
New API that will lookup an osd_dev by its osd_dev_info.
This is used by pNFS-objects for cross network global device
identification. And by exofs multy-device support, the device
info is specified in the on-disk exofs device table.
osduld_device_info() - NEW
Given an osd_dev handle returns its associated osd_dev_info.
The ULD fetches this information at startup and hangs it on
each OSD device. (This is a fast operation that can be called
at any condition)
osduld_device_same() - NEW
With a given osd_dev at one hand and an osd_dev_info
at another, we would like to know if they are the same
device.
Two osd_dev handles can be checked by:
osduld_device_same(od1, osduld_device_info(od2));
osd_auto_detect_ver() - REVISED
Now returns an osd_dev_info structure. Is only called once
by ULD as before. See added comments for how to use.

The true logic of this patch will be clear in the next patch where we
use the class_find_device() API. When doing so the use of an internal
kref leaves us a narrow window where a find is started while the actual
object can go away. Using the device's kobj reference solves this
problem because now the same kref is used for both operations. (Remove
and find)
Core changes
* Embed a struct device in uld_ structure and use device_register
instead of devie_create. Set __remove to be the device release
function.
* __uld_get/put is just get_/put_device. Now every thing is accounted
for on the device object. Internal kref is removed.
* At __remove() we can safely de-allocate the uld_ structure. (The
function has moved to avoid forward declaration)
Some cleanups
* Use class register/unregister is cleaner for this driver now.
* cdev ref-counting games are no longer necessary
I have incremented the device version string in case of new bugs.
Note: Previous bugfix of taking the reference around fput() still
applies.

This patch fixes this issue by adding dedicated work queue thread
fc_exch_workqueue for exch delayed work and then flush this work

There are cases outside of our control that may result in a transmit
skb being linearized in dev_queue_xmit. There are a couple of bugs
in libfc/fcoe that can result in a panic at that point. This patch
contains two fixes to prevent those panics.
1) use fast cloning instead of shared skbs with dev_queue_xmit
dev_queue_xmit doen't want shared skbuffs being passed in, and
__skb_linearize will BUG if the skb is shared. FCoE is holding an extra
reference around the call to dev_queue_xmit, so that when it returns an
error code indicating the frame has been dropped it can maintain it's
own backlog and retransmit. Switch to using fast skb cloning for this
instead.
2) don't append compound pages as > PAGE_SIZE skb fragments
fc_fcp_send_data will append pages from a scatterlist to the nr_frags[]
if the netdev supports it. But, it's using > PAGE_SIZE compound pages
as a single skb_frag. In the highmem linearize case that page will be
passed to kmap_atomic to get a mapping to copy out of, but
kmap_atomic will only allow access to the first PAGE_SIZE part.
The memcpy will keep going and cause a page fault once is crosses the
first boundary.
If fc_fcp_send_data uses linear buffers from the start, it calls
kmap_atomic one PAGE_SIZE at a time. That same logic needs to be
applied when setting up skb_frags.

DID_NO_CONNECT is not a nice value to use for pkt alloc failures,
because you can probably retry and IO will become available again.
For the device reset callout, we do not want to set the scsi command
result for the above reason, and because we do not need to set
the scsi_cmd->result in this path. We and other drivers do not set it
for success for example, and we do not set it for other failure.
And scsi-ml does not send every command through this path, and it is
not expecting us to use the scsi_cmnd struct like a cmd coming thruogh
queuecommand. I think it is more for storage in case we need a cmd
struct for a tmf and to give us certain params like the LUN.

Use libfcoe as a common FIP implementation with fcoe.
FIP or non-FIP mode is fully automatic if the firmware
supports and enables it.
Even if FIP is not supported, this uses libfcoe for the non-FIP
handling of FLOGI and its response.
Use the new lport_set_port_id() notification to capture
successful FLOGI responses and port_id resets.
While transitioning between Ethernet and FC mode, all rx and
tx FC frames are queued. In Ethernet mode, all frames are
passed to the exchange manager to capture FLOGI responses.
Change to set data_src_addr to the ctl_src_addr whenever it
would have previously been zero because we're not logged in.
This seems safer so we'll never send a frame with a 0 source MAC.
This also eliminates a special case for sending FLOGI frames.

There was a locking problem where the fip->lock was held during
the call to update_mac(). The rtnl_lock() must be taken before
the fip->lock, not the other way around. This fixes that.
Now that fcoe_ctlr_recv_flog() is called only from the response handler
to a FLOGI request, some checking can be eliminated. Instead of calling
update_mac(), just fill in the granted_mac address for the passed-in
frame (skb).
Eliminate the passed-in source MAC address since it is also in the skb.
Also, in fcoe, call fcoe_set_src_mac() directly instead of going thru
the fip function pointer. This will generate less code.
Then, since fip isn't needed for LOGO response, use lport as the arg.

This is to notify the LLD when an FC_ID is assigned to the local port.
The fnic driver needs to push the assigned FC_ID to firmware.
It currently does this by intercepting the FLOGI responses, and
in order to make that code more common with FIP and NPIV, it
makes more sense to wait until the local port has completely
handled the FLOGI or FDISC response. Also, when we fix
point-to-point FC_ID assignment, we'll need this callback as well.
Add a call to the libfc template, which is called whenever
the local port FC_ID is being assigned. It defaults to
fc_lport_set_fid(), supplied by libfc.
As additional benefit of this function, the LLD may determine
the MAC address that caused the change by looking at the received frame.
We also print the assigned port ID as long as it isn't 0.
Setting port ID to 0 happens often in reset while retrying FLOGI,
and would be uninteresting. This replaces the previous message
which didn't identify the host adapter instance.

link down event not to be reported, and /sys shows the host "Online".
Currently, in FIP mode, if an FCF times out, then link to libfc
is reported as down, to stop FLOGIs. That interferes with the LLD
link down being reported.
Users really need to know the physical link information, to diagnose
cabling issues, so physical link status should be reported to libfc.
If the selected FCF needs to be reported, that should be done
separately, in a later patch.

Adds last_can_queue_ramp_down_time and updates this on every
ramp down. If last_can_queue_ramp_down_time is not zero then
do ramp up on any IO completion in added fc_fcp_can_queue_ramp_up.
Reset last_can_queue_ramp_down_time to zero once can_queue
is ramped up to added max_can_queue limit, this is to avoid any
more ramp up attempts on subsequent IO completion.
The ramp down and up are skipped for FC_CAN_QUEUE_PERIOD
to avoid infrequent changes to can_queue, this required
keeping track of ramp up time also in last_can_queue_ramp_up_time.
Adds code to ramp down can_queue if lp->qfull is set, with added
new ramp up code the can_queue will be increased after
FC_CAN_QUEUE_PERIOD, therefore it is safe to do ramp down
without fsp in this case and will avoid thrash. This required
fc_fcp_can_queue_ramp_down locking change so that it can be
called with Scsi_Host lock held.

Currently can_queue is reduced only if frame alloc fails
during fc_fcp_send_data but frame alloc can fail at several

reduced for any FCP frame alloc failure.
This patch adds fc_fcp_frame_alloc for all FCP frame allocations
and if fc_frame_alloc fails in fc_fcp_frame_alloc then reduce
can_queue in fc_fcp_frame_alloc, this will reduce can_queue for

The FIP code in libfcoe needed several changes to support NPIV
1) dst_src_addr needs to be managed per-n_port-ID for FPMA fabrics with NPIV
enabled. Managing the MAC address is now handled in fcoe, with some slight
changes to update_mac() and a new get_src_addr() function pointer.
2) The libfc elsct_send() hook is used to setup FCoE specific response
handlers for FIP encapsulated ELS exchanges. This lets the FCoE specific
handling know which VN_Port the exchange is for, and doesn't require
tracking OX_IDs. It might be possible to roll back to the full FIP frame
in these, but for now I've just stashed the contents of the MAC address
descriptor in the skb context block for later use. Also, because
fcoe_elsct_send() just passes control on to fc_elsct_send(), all transmits
still come through the normal frame_send() path.
3) The NPIV changes added a mutex hold in the keep alive sending, the lport
mutex is protecting the vport list. We can't take a mutex from a timer,
so move the FIP keep alive logic to the link work struct.

This patch moves all non-common routines and function prototypes

A result of moving the fc_exch_seq_send, fc_seq_els_rsp_send, fc_exch_alloc
and fc_seq_start_next prototypes out of libfc.h is that they were no longer
being imported into fc_exch.c when libfc.h was included. This caused errors
where routines in fc_exch.c were looking for undefined symbols. To fix this
this patch reorganizes fc_seq_alloc, fc_seq_start_next and
fc_seq_start_next_locked. This move also made it so that
fc_seq_start_next_locked did not need to be prototyped at the top of

The OS interrupt vectors were getting allocated before the interrupt
resources were mapped from hardware. For Legacy interrupts, since
they are shared with other devices, as soon as an interrupt is
registered with the OS, it can fire while the fnic isr resource is
still unmapped. This can cause crash because of access to unmapped resources.
For MSIX and MSI, since interrupts are not shared with other devices,
this problem didnt happen, because the interrupt is enabled as the last
step before returning from _probe. For Legacy however, since the
interrupt is shared, the handler can be called as soon as it is registered.
Solution is to register interrupt handlers with OS as last step before
enabling device interrupts.

Current FC HBA queue_depth ramp up code depends on last queue
full time. The sdev already has last_queue_full_time field to
track last queue full time but stored value is truncated by
last four bits.
So this patch updates last_queue_full_time without truncating
last 4 bits to store full value and then updates its only
current usages in scsi_track_queue_full to ignore last four bits
to keep current usages same while also use this field
in added ramp up code.
Adds scsi_handle_queue_ramp_up to ramp up queue_depth on
successful completion of IO. The scsi_handle_queue_ramp_up will
do ramp up on all luns of a target, just same as ramp down done
on all luns on a target.
The ramp up is skipped in case the change_queue_depth is not
supported by LLD or already reached to added max_queue_depth.
Updates added max_queue_depth on every new update to default
queue_depth value.
The ramp up is also skipped if lapsed time since either last
queue ramp up or down is less than LLD specified
queue_ramp_up_period.
Adds queue_ramp_up_period to sysfs but only if change_queue_depth
is supported since ramp up and queue_ramp_up_period is needed only
in case change_queue_depth is supported first.
Initializes queue_ramp_up_period to 120HZ jiffies as initial

Timer crashes were caused by freeing a struct fc_rport_priv
with a timer pending, causing the timer facility list to be
corrupted. This was during FC uplink flap tests with a lot
of targets.
After discovery, we were doing an PLOGI on an rdata that was
in DELETE state but not yet removed from the lookup list.
This moved the rdata from DELETE state to PLOGI state.
If the PLOGI exchange allocation failed and needed to be
retried, the timer scheduling could race with the free
being done by fc_rport_work().
When fc_rport_login() is called on a rport in DELETE state,
move it to a new state RESTART. In fc_rport_work, when
handling a LOGO, STOPPED or FAILED event, look for restart
state. In the RESTART case, don't take the rdata off the
list and after the transport remote port is deleted and
exchanges are reset, re-login to the remote port.
Note that the new RESTART state also corrects a problem we
had when re-discovering a port that had moved to DELETE state.
In that case, a new rdata was created, but the old rdata
would do an exchange manager reset affecting the FC_ID
for both the new rdata and old rdata. With the new state,
the new port isn't logged into until after any old exchanges
are reset.

Driver was processing a fixed max number of cq descriptors per ISR. For
instance, for the SCSI IO queue, number of IOs processed per ISR were 8.
If hardware writes 9 cq descriptors to the cq and generates an interrupt,
driver would process only 8 descriptors and decrement the outstanding
credit count by 8. Unless another interrupt event happens, the hw does
not generate any additional interrupt. This results in the cq descriptor
sitting in the queue without being procesed and can cause IO timeouts
and aborts.
Modify all ISR functions to process all queued cq descriptors in one shot.
Since bulk of ELS frame processing is done in thread context and bulk
of SCSI IO processing is done in soft ISR deferred context, the cycles
spent in the ISR per cq descriptor is small.

I was running into several different panics under stress, which I traced down
to a few different possible slab corruption issues in error handling paths.
I have not yet looked into why these exchange sends fail, but with these
fixes my test system is much more stable under stress than before.
fc_elsct_send() could fail and either leave the passed in frame intact
(failure in fc_ct/els_fill) or the frame could have been freed if the
failure was is fc_exch_seq_send(). The caller had no way of knowing, and
there was a potential double free in the error handling in fc_fcp_rec().
Make fc_elsct_send() always free the frame before returning, and remove the
fc_frame_free() call in fc_fcp_rec().
While fc_exch_seq_send() did always consume the frame, there were double free
bugs in the error handling of fc_fcp_cmd_send() and fc_fcp_srr() as well.
Numerous calls to error handling routines (fc_disc_error(),
fc_lport_error(), fc_rport_error_retry() ) were passing in a frame pointer that
had already been freed in the case of an error. I have changed the call
sites to pass in a NULL pointer, but there may be more appropriate error
codes to use.
Question: Why do these error routines take a frame pointer anyway? I
understand passing in a pointer encoded error to the response handlers, but
the error routines take no action on a valid pointer and should never be
called that way.

instance to make sure LLD has all necessary resources allocated and setup
properly before passing FCoE traffic. Similarly, calls ndo_fcoe_disable()

In case of sequence offload, in fc_fcp_send_data(), the skb_fill_page_info()
called may end up adding more frags to the skb_shinfo(fp_skb(fp))->frags[],
exceeding SKB_MAX_FRAGS, this eventually corrupts the memory. I am adding the
FR_FRAME_SG_LEN back, but as SKB_MAX_FRAGS -1, leaving 1 for our fcoe_eof_crc
page. And send will be broken into multiple large sends if the frame already
contains more frags than skb handle.

Add a define of FCOE_MTU as 2158 bytes and use FCOE_MTU when the LLD is found
to support NETIF_F_FCOE_MTU. The lport->mfs is then calculated out of the
2158 FCOE_MTU. Otherwise, we stick with the netdev->mtu, i.e., LAN MTU. Also,
change the notification on NETDEV_CHANGEMTU event to bypass changing mfs when
LAN MTU is changed if NETIF_F_FCOE_MTU is supported.

It's possible and harmless to get FLOGI timeouts
while in RESET state. Don't do a WARN_ON in that case.
Also, split out the other WARN_ONs in fc_lport_timeout, so
we can tell which one is hit by its line number.

This bug is exposed when there is a link flap in LLD. Particularly, when it
happens right after a SCSI write command is sent out, no FCP_DATA is sent,
causing fsp->status_code to be set as FC_DATA_UNDRUN in fc_fcp_complete_locked
even no SCSI status is received. Consequently, fc_io_compl treats this as DID_OK.
This results in SCSI returning successful to the initial I/O request even
there is no DATA actually sent. Particularly, if you run an I/O tool w/ data
verification on, the read back for verification is gonna fail.
This is fixed here by checking when FC_DATA_UNDRUN happens, SCSI status is
received w/ FC_SRB_RCV_STATUS set in fsp->state.

A received Fibre Channel ELS PRLI request contains a bit that
indicates whether the remote port supports certain retry processing
sequences. The test for this bit was somehow coded to use multiply

This case would apply only for target mode operation, and it is
