| * target: Fix percpu_ref_put race in transport_lun_remove_cmdNicholas Bellinger2014-01-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a percpu_ref_put race for se_lun->lun_ref in transport_lun_remove_cmd() where ->lun_ref could end up being put more than once per command via different target completion and fabric release contexts. It adds a cmpxchg() for se_cmd->lun_ref_active to ensure that percpu_ref_put() is only ever called once per se_cmd. This bug was manifesting itself as a LUN shutdown regression bug in >= v3.13 code, where percpu_ref_kill() would end up hanging indefinately due to the incorrect percpu_ref count. (Change se_cmd->lun_ref_active from bool -> int to force at least a 4-byte cmpxchg with MIPS ll/sc ins. - Fengguang) Reported-by: Tommy Apel <tommyapeldk@gmail.com> Cc: Tommy Apel <tommyapeldk@gmail.com> Cc: <stable@vger.kernel.org> #3.13+ Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

| * iscsi-target: Convert gfp_t parameter to task state bitmaskNicholas Bellinger2014-01-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | This patch propigates the use of task state bitmask now used by percpu_ida_alloc() up the iscsi-target callchain, replacing the use of GFP_ATOMIC for TASK_RUNNING, and GFP_KERNEL for TASK_INTERRUPTIBLE. Also, drop the unnecessary gfp_t parameter to isert_allocate_cmd(), and just pass TASK_INTERRUPTIBLE into iscsit_allocate_cmd(). Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes percpu_ida_alloc() + callers to accept task state bitmask for prepare_to_wait() for code like target/iscsi that needs it for interruptible sleep, that is provided in a subsequent patch. It now expects TASK_UNINTERRUPTIBLE when the caller is able to sleep waiting for a new tag, or TASK_RUNNING when the caller cannot sleep, and is forced to return a negative value when no tags are available. v2 changes: - Include blk-mq + tcm_fc + vhost/scsi + target/iscsi changes - Drop signal_pending_state() call v3 changes: - Only call prepare_to_wait() + finish_wait() when != TASK_RUNNING (PeterZ) Reported-by: Linus Torvalds <torvalds@linux-foundation.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Ingo Molnar <mingo@redhat.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Jens Axboe <axboe@kernel.dk> Signed-off-by: Kent Overstreet <kmo@daterainc.com> Cc: <stable@vger.kernel.org> #3.12+ Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

| * | [media] vb2: retry start_streaming in case of insufficient buffersHans Verkuil2014-01-071-4/+11

This means applications no longer need to know how many buffers need to be queued before STREAMON can be called. This is particularly useful for output stream I/O. If a DMA engine needs at least X buffers before it can start streaming, then for applications to get a buffer out as soon as possible they need to know the minimum number of buffers to queue before STREAMON can be called. You can't just try STREAMON after every buffer since on failure STREAMON will dequeue all your buffers. (Is that a bug or a feature? Frankly, I'm not sure). This patch simplifies applications substantially: they can just call STREAMON at the beginning and then start queuing buffers and the DMA engine will kick in automagically once enough buffers are available. This also fixes using write() to stream video: the fileio implementation calls streamon without having any queued buffers, which will fail today for any driver that requires a minimum number of buffers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than taking the mmap semaphore at a relatively high-level function, push it down to the place where it is really needed. It was placed in vb2_queue_or_prepare_buf() to prevent racing with other vb2 calls. The only way I can see that a race can happen is when two threads queue the same buffer. The solution for that it to introduce a PREPARING state. Moving it down offers opportunities to simplify the code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Both the PAL and NTSC standards are interlaced where a frame consist of two fields. Total number of lines in a frame in both systems are an odd number so the two fields will have different length. In the 625 line standard ("PAL") the odd field of the frame is transmitted first, while in the 525 standard ("NTSC") the even field is transmitted first. This adds the possibility to change output config between the fields and standards. This setting will reduce the "format-jitter" on the signal sent by the pixelport moving the difference between the fields to vertical front/back-porch only.

For ADV7842_MODE_COMP, automatic CSC mode will be selected. See table 48 on page 281 in "ADV7842 Hardware Manual, Rev. 0, January 2011" for details. Make sure that when switching inputs the RGB quantization range is updated as well. Also updated the platform_data in ezkit to ensure that what was the old default value is now explicitly specified, so the behavior for that board is unchanged.

| * | [media] omap24xx/tcm825x: move to staging for future removalHans Verkuil2013-12-201-305/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The omap24xx driver and the tcm825x sensor driver are the only two remaining drivers to still use the old deprecated v4l2-int-device API. Nobody maintains these drivers anymore. But unfortunately the v4l2-int-device API is used by out-of-tree drivers (MXC platform). This is a very bad situation since as long as this deprecated API stays in the kernel there is no reason for those out-of-tree drivers to convert. This patch moves v4l2-int-device and the two drivers that depend on it to staging in preparation for their removal. If someone would be interested in getting these drivers to work, then start with this since it's not very far from the state where they used to work: <URL:http://vihersipuli.retiisi.org.uk/cgi-bin/gitweb.cgi?p=~sailus/linux-omap/.git;a=summary> The branch is n800-cam. Porting to up-to-date APIs can then be done. David might have done some work in that area, so check with him first.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the ISI driver it reads the config register to get original value, then set the correct FRATE_DIV and YCC_SWAP_MODE directly. This will cause some bits overlap. So we need to clear these bits first, then set correct value. This patch fix it.

So this information belongs to the platform data and should not be hardcoded in the subdevice driver.
