2015-09-04genalloc: add name arg to gen_pool_get() and devm_gen_pool_create()Vladimir Zapolskiy1-1/+1
This change modifies gen_pool_get() and devm_gen_pool_create() client interfaces adding one more argument "name" of a gen_pool object. Due to implementation gen_pool_get() is capable to retrieve only one gen_pool associated with a device even if multiple gen_pools are created, fortunately right at the moment it is sufficient for the clients, hence provide NULL as a valid argument on both producer devm_gen_pool_create() and consumer gen_pool_get() sides. Because only one created gen_pool per device is addressable, explicitly add a restriction to devm_gen_pool_create() to create only one gen_pool per device, this implies two possible error codes returned by the function, account it on client side (only misc/sram). This completes client side changes related to genalloc updates.

2015-07-17[media] coda: add macroblock tiling supportPhilipp Zabel1-49/+25
Storing internal frames in macroblock tiled order improves memory access patterns by allowing increased burst sizes when transferring the uncompressed macroblocks to or from main memory. The translation logic only supports a single chroma base address, so this is only supported for the chroma interleaved NV12 format. Since the rotator used to copy the decoder output into the v4l2 capture buffers does not seem to support the tiled format correctly, only enable it in the encoder for now.

2015-06-30genalloc: rename of_get_named_gen_pool() to of_gen_pool_get()Vladimir Zapolskiy1-1/+1
To be consistent with other kernel interface namings, rename of_get_named_gen_pool() to of_gen_pool_get(). In the original function name "_named" suffix references to a device tree property, which contains a phandle to a device and the corresponding device driver is assumed to register a gen_pool object. Due to a weak relation and to avoid any confusion (e.g. in future possible scenario if gen_pool objects are named) the suffix is removed.

2015-05-12[media] coda: Set last buffer flag and fix EOS eventPhilipp Zabel1-16/+11
Setting the last buffer flag causes the videobuf2 core to return -EPIPE from DQBUF calls on the capture queue after the last buffer is dequeued.

2015-04-10[media] coda: move parameter buffer in together with context buffer allocationPhilipp Zabel1-12/+0

2015-04-10[media] coda: allocate bitstream buffer from REQBUFS, size depends on the formatPhilipp Zabel1-22/+0
Allocating the bitstream buffer only when the format is set allows to guarantee that at least two frames fit into the bitstream buffer. For small frame sizes a smaller bitstream buffer can be allocated. Since the bitstream buffer size now depends on the format, replace CODA_MAX_FRAME_SIZE with ctx->bitstream.size where appropriate and remove the now unused constant. Since REQBUFS can be called multiple times, but the format can't be changed unless REQBUFS 0 was called before, we can just keep the allocated context and bitstream buffers if REQBUFS is called multiple times with a non-zero buffer count.

2014-12-05media / PM: Replace CONFIG_PM_RUNTIME with CONFIG_PMRafael J. Wysocki1-2/+2
After commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks depending on CONFIG_PM_RUNTIME may now be changed to depend on CONFIG_PM. The alternative of CONFIG_PM_SLEEP and CONFIG_PM_RUNTIME may be replaced with CONFIG_PM too. Make these changes everywhere under drivers/media/.

2014-11-03[media] coda: Unregister v4l2 upon alloc_workqueue() errorFabio Estevam1-1/+2
If alloc_workqueue() fails, we should go to the 'err_v4l2_register' label, which will unregister the v4l2 device. Signed-off-by: Fabio Estevam <[email protected]> Acked-by: Philipp Zabel <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
2014-11-03[media] coda: Call v4l2_device_unregister() from a single locationFabio Estevam1-8/+12
Instead of calling v4l2_device_unregister() in multiple locations within the error paths, let's call it from a single location to make the error handling simpler.

2014-10-28[media] coda: re-queue buffers if start_streaming failsPhilipp Zabel1-2/+2
Patch b906352c2338 ([media] coda: dequeue buffers if start_streaming fails) incorrectly marked buffers as DEQUEUED in case of start_streaming failure, when in fact they should be set to QUEUED. The videobuf2 core warns about this.

2014-10-28[media] coda: allow userspace to set compressed buffer size in a certain rangePhilipp Zabel1-8/+17
For small frame sizes, allocating 1 MiB per compressed buffer is a waste of space. On the other hand, incompressible 1080p data can produce JPEGs larger than 1 MiB at higher quality settings. Allow userspace to set the compressed buffer size and clamp the value to a sensible range. Also set the initial sizeimage to a value inside the range allowed by try_fmt. While at it, reduce the default image size to a maximum of 1920*1088 (otherwise JPEG will default to 8k*8k and 96 MiB buffers).
