[media] media: s5p-mfc: fix sparse warnings

2015-06-05T09:37:24+00:00

Commits a0f10c131cc49d7d84394beb7903e1f246331224 and 6c9fe765360efa97c63b89af685b620baf5e0012 ("media: s5p-mfc: fix broken pointer cast on 64bit arch") fixed issue with lossy cast on 64-bit architectures. However it also removed __iomem attribute from that cast. This leads to sparse warnings. This patch fixes those warnings by adding __iomem cast in case of v6+ code version and replacing readl/writel by simple u32 load/store operations in case of v5 code (which is called on system memory allocated by dma_alloc_coherent() instead of io registers).

[media] s5p-mfc: Set last buffer flag

2015-05-12T06:54:34+00:00

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. Signed-off-by: Philipp Zabel Signed-off-by: Kamil Debski Signed-off-by: Mauro Carvalho Chehab

[media] s5p-mfc: set allow_zero_bytesused flag for vb2_queue_init

2015-04-10T12:47:15+00:00

The s5p-mfc driver interprets a buffer with bytesused equal to 0 as a special case indicating end-of-stream. After vb2: fix bytesused == 0 handling (8a75ffb) patch videobuf2 modified the value of bytesused if it was 0. The allow_zero_bytesused flag was added to videobuf2 to keep backward compatibility.

[media] media: s5p-mfc: fix mmap support for 64bit arch

2015-04-02T19:59:40+00:00

TASK_SIZE is depends on the systems architecture (32 or 64 bits) and it should not be used for defining offset boundary for mmaping buffers for CAPTURE and OUTPUT queues. This patch fixes support for MMAP calls on the CAPTURE queue on 64bit architectures (like ARM64). Signed-off-by: Marek Szyprowski Signed-off-by: Kamil Debski Signed-off-by: Mauro Carvalho Chehab
