2014-04-16platform: Fix timberdale dependenciesJean Delvare1-1/+1
VIDEO_TIMBERDALE selects TIMB_DMA which itself depends on MFD_TIMBERDALE, so VIDEO_TIMBERDALE should either select or depend on MFD_TIMBERDALE as well. I chose to make it depend on it because I think it makes more sense and it is consistent with what other options are doing. Adding a "|| HAS_IOMEM" to the TIMB_DMA dependencies silenced the kconfig warning about unmet direct dependencies but it was wrong: without MFD_TIMBERDALE, TIMB_DMA is useless as the driver has no device to bind to.

2014-04-15[media] media: davinci: vpfe: make sure all the buffers unmapped and releasedLad, Prabhakar1-0/+2
this patch makes sure that it terminates if any IO in progress and also makes sure that all the buffers are unmapped. It was observed that with several runs of application the application sometimes failed to allocate memory, This patch makes sure it all the buffers are released. Using kmemleak it was found that buffer were not released, this patch fixes following issue, echo scan > /sys/kernel/debug/kmemleak Kernel message reads: memleak: 3 new suspected memory leaks (see /sys/kernel/debug/kmemleak) Then, cat /sys/kernel/debug/kmemleak unreferenced object 0xc564a480 (size 192): comm "mttest", pid 764, jiffies 4294945878 (age 487.160s) hex dump (first 32 bytes): 00 00 00 00 28 07 07 20 d0 02 00 00 e0 01 00 00 ....(.. ........ 00 00 00 00 00 64 05 00 01 00 00 00 01 00 00 00 .....d.......... backtrace: [<c00a98dc>] create_object+0x10c/0x28c [<c03ba8ec>] kmemleak_alloc+0x3c/0x70 [<c00a67c0>] __kmalloc+0x11c/0x1d4 [<c02b6f48>] __videobuf_alloc+0x1c/0x3c [<c02b6194>] videobuf_alloc_vb+0x38/0x80 [<c02b6638>] __videobuf_mmap_setup+0x9c/0x108 [<c02b6da0>] videobuf_reqbufs.part.10+0x12c/0x1bc [<c02b6e9c>] videobuf_reqbufs+0x6c/0x8c [<c02be2c4>] vpfe_reqbufs+0xcc/0x130 [<c02aae90>] v4l_reqbufs+0x50/0x54 [<c02aab54>] __video_do_ioctl+0x260/0x2c4 [<c02a9dd4>] video_usercopy+0xf0/0x310 [<c02aa008>] video_ioctl2+0x14/0x1c [<c02a562c>] v4l2_ioctl+0x104/0x14c [<c00bd320>] do_vfs_ioctl+0x80/0x2d0 [<c00bd5b4>] SyS_ioctl+0x44/0x64 unreferenced object 0xc564ac00 (size 192): comm "mttest", pid 764, jiffies 4294945878 (age 487.160s) hex dump (first 32 bytes): 01 00 00 00 28 07 07 20 d0 02 00 00 e0 01 00 00 ....(.. ........ 00 00 00 00 00 64 05 00 01 00 00 00 01 00 00 00 .....d.......... backtrace: [<c00a98dc>] create_object+0x10c/0x28c [<c03ba8ec>] kmemleak_alloc+0x3c/0x70 [<c00a67c0>] __kmalloc+0x11c/0x1d4 [<c02b6f48>] __videobuf_alloc+0x1c/0x3c [<c02b6194>] videobuf_alloc_vb+0x38/0x80 [<c02b6638>] __videobuf_mmap_setup+0x9c/0x108 [<c02b6da0>] videobuf_reqbufs.part.10+0x12c/0x1bc [<c02b6e9c>] videobuf_reqbufs+0x6c/0x8c [<c02be2c4>] vpfe_reqbufs+0xcc/0x130 [<c02aae90>] v4l_reqbufs+0x50/0x54 [<c02aab54>] __video_do_ioctl+0x260/0x2c4 [<c02a9dd4>] video_usercopy+0xf0/0x310 [<c02aa008>] video_ioctl2+0x14/0x1c [<c02a562c>] v4l2_ioctl+0x104/0x14c [<c00bd320>] do_vfs_ioctl+0x80/0x2d0 [<c00bd5b4>] SyS_ioctl+0x44/0x64 unreferenced object 0xc564a180 (size 192): comm "mttest", pid 764, jiffies 4294945880 (age 487.140s) hex dump (first 32 bytes): 02 00 00 00 28 07 07 20 d0 02 00 00 e0 01 00 00 ....(.. ........ 00 00 00 00 00 64 05 00 01 00 00 00 01 00 00 00 .....d.......... backtrace: [<c00a98dc>] create_object+0x10c/0x28c [<c03ba8ec>] kmemleak_alloc+0x3c/0x70 [<c00a67c0>] __kmalloc+0x11c/0x1d4 [<c02b6f48>] __videobuf_alloc+0x1c/0x3c [<c02b6194>] videobuf_alloc_vb+0x38/0x80 [<c02b6638>] __videobuf_mmap_setup+0x9c/0x108 [<c02b6da0>] videobuf_reqbufs.part.10+0x12c/0x1bc [<c02b6e9c>] videobuf_reqbufs+0x6c/0x8c [<c02be2c4>] vpfe_reqbufs+0xcc/0x130 [<c02aae90>] v4l_reqbufs+0x50/0x54 [<c02aab54>] __video_do_ioctl+0x260/0x2c4 [<c02a9dd4>] video_usercopy+0xf0/0x310 [<c02aa008>] video_ioctl2+0x14/0x1c [<c02a562c>] v4l2_ioctl+0x104/0x14c [<c00bd320>] do_vfs_ioctl+0x80/0x2d0 [<c00bd5b4>] SyS_ioctl+0x44/0x64 Reported-by: Jimmy Ho <jimmygge@gmail.com> Signed-off-by: Lad, Prabhakar <prabhakar.csengg@gmail.com> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

2014-04-07[media] v4l: ti-vpe: Set correct field parameter for output and capture buffersArchit Taneja1-1/+12
The vpe driver wasn't setting the correct field parameter for dequed CAPTURE type buffers for the case where the captured output is progressive. Set the field to V4L2_FIELD_NONE for the completed destination buffers when the captured output is progressive. For OUTPUT type buffers, a queued buffer's field is forced to V4L2_FIELD_NONE if the pixel format(configured through s_fmt for the buffer type V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE specifies) the field type isn't interlaced. If the pixel format specified was V4L2_FIELD_ALTERNATE, and the queued buffer's field isn't V4L2_FIELD_TOP or V4L2_FIELD_BOTTOM, the vb2 buf_prepare op returns an error. This ensures compliance, and that the dequeued output and captured buffers contain the field type that the driver used internally.

2014-04-07[media] v4l: ti-vpe: Use video_device_release_emptyArchit Taneja1-1/+1
The video_device struct is currently embedded in the driver data struct vpe_dev. A vpe_dev instance is allocated by the driver, and the memory for the vfd is a part of this struct. The v4l2 core, however, manages the removal of the vfd region, through the video_device's .release() op, which currently is the helper video_device_release. This causes memory corruption, and leads to issues when we try to re-insert the vpe module. Use the video_device_release_empty helper function instead.

2014-04-07[media] v4l: ti-vpe: Make sure in job_ready that we have the needed number ↵Archit Taneja1-0/+3
of dst_bufs VPE has a ctrl parameter which decides how many mem to mem transactions the active job from the job queue can perform. The driver's job_ready() made sure that the number of ready source buffers are sufficient for the job to execute successfully. But it didn't make sure if there are sufficient ready destination buffers in the capture queue for the VPE output. If the time taken by VPE to process a single frame is really slow, then it's possible that we don't need to imply such a restriction on the dst queue, but really fast transactions(small resolution, no de-interlacing) may cause us to hit the condition where we don't have any free buffers for the VPE to write on. Add the extra check in job_ready() to make sure we have the sufficient amount of destination buffers.

2014-03-11[media] vb2: only call start_streaming if sufficient buffers are queuedHans Verkuil4-22/+4
In commit 02f142ecd24aaf891324ffba8527284c1731b561 support was added to start_streaming to return -ENOBUFS if insufficient buffers were queued for the DMA engine to start. The vb2 core would attempt calling start_streaming again if another buffer would be queued up. Later analysis uncovered problems with the queue management if start_streaming would return an error: the buffers are enqueued to the driver before the start_streaming op is called, so after an error they are never returned to the vb2 core. The solution for this is to let the driver return them to the vb2 core in case of an error while starting the DMA engine. However, in the case of -ENOBUFS that would be weird: it is not a real error, it just says that more buffers are needed. Requiring start_streaming to give them back only to have them requeued again the next time the application calls QBUF is inefficient. This patch changes this mechanism: it adds a 'min_buffers_needed' field to vb2_queue that drivers can set with the minimum number of buffers required to start the DMA engine. The start_streaming op is only called if enough buffers are queued. The -ENOBUFS handling has been dropped in favor of this new method. Drivers are expected to return buffers back to vb2 core with state QUEUED if start_streaming would return an error. The vb2 core checks for this and produces a warning if that didn't happen and it will forcefully reclaim such buffers to ensure that the internal vb2 core state remains consistent and all buffer-related resources have been correctly freed and all op calls have been balanced. __reqbufs() has been updated to check that at least min_buffers_needed buffers could be allocated. If fewer buffers were allocated then __reqbufs will free what was allocated and return -ENOMEM. Based on a suggestion from Pawel Osciak. __create_bufs() doesn't do that check, since the use of __create_bufs assumes some advance scenario where the user might want more control. Instead streamon will check if enough buffers were allocated to prevent streaming with fewer than the minimum required number of buffers.

2014-03-06[media] of: move common endpoint parsing to drivers/ofPhilipp Zabel2-6/+6
This patch adds a new struct of_endpoint which is then embedded in struct v4l2_of_endpoint and contains the endpoint properties that are not V4L2 (or even media) specific: the port number, endpoint id, local device tree node and remote endpoint phandle. of_graph_parse_endpoint parses those properties and is used by v4l2_of_parse_endpoint, which just adds the V4L2 MBUS information to the containing v4l2_of_endpoint structure.

2014-03-06[media] of: move graph helpers from drivers/media/v4l2-core to drivers/ofPhilipp Zabel3-5/+7
This patch moves the parsing helpers used to parse connected graphs in the device tree, like the video interface bindings documented in Documentation/devicetree/bindings/media/video-interfaces.txt, from drivers/media/v4l2-core/v4l2-of.c into drivers/of/base.c. This allows to reuse the same parser code from outside the V4L2 framework, most importantly from display drivers. The functions v4l2_of_get_next_endpoint, v4l2_of_get_remote_port, and v4l2_of_get_remote_port_parent are moved. They are renamed to of_graph_get_next_endpoint, of_graph_get_remote_port, and of_graph_get_remote_port_parent, respectively. Since there are not that many current users yet, switch all of them to the new functions right away.
