2016-06-07[media] s5p-mfc: don't close instance after free OUTPUT buffersayaka1-1/+0
User-space applications can use the VIDIOC_REQBUFS ioctl to determine if a memory mapped, user pointer or DMABUF based I/O is supported by the driver. So a set of VIDIOC_REQBUFS ioctl calls will be made with count 0 and then the real VIDIOC_REQBUFS call with count == n. But for count 0, the driver not only frees the buffer but also closes the MFC instance and s5p_mfc_ctx state is set to MFCINST_FREE. The VIDIOC_REQBUFS handler for the output device checks if the s5p_mfc_ctx state is set to MFCINST_INIT (which happens on an VIDIOC_S_FMT) and fails otherwise. So after a VIDIOC_REQBUFS(n), future VIDIOC_REQBUFS(n) calls will fails unless a VIDIOC_S_FMT ioctl calls happens before the reqbufs. But applications may first set the format and then attempt to determine the I/O methods supported by the driver (for example Gstramer does it) so the state won't be set to MFCINST_INIT again and VIDIOC_REQBUFS will fail. To avoid this issue, only free the buffers on VIDIOC_REQBUFS(0) but don't close the MFC instance to allow future VIDIOC_REQBUFS(n) calls to succeed.

2016-06-03media: s5p-mfc: add iommu supportMarek Szyprowski2-0/+103
This patch adds support for IOMMU to s5p-mfc device driver. MFC firmware is limited and it cannot use the default configuration. If IOMMU is available, the patch disables the default DMA address space configuration and creates a new address space of size limited to 256M and base address set to 0x20000000. For now the same address space is shared by both 'left' and 'right' memory channels, because the DMA/IOMMU frameworks do not support configuring them separately. This is not optimal, but besides limiting total address space available has no other drawbacks (MFC firmware supports 256M of address space per each channel).

Add a helper function for device drivers to set DMA's max_seg_size. Setting it to largest possible value lets DMA-mapping API always create contiguous mappings in DMA address space. This is essential for all devices, which use dma-contig videobuf2 memory allocator and shared buffers. Till now, the only case when vb2-dma-contig really 'worked' was a case where userspace provided USERPTR buffer, which was in fact mmaped contiguous buffer from the other v4l2/drm device. Also DMABUF made of contiguous buffer worked only when its exporter did not split it into several chunks in the scatter-list. Any other buffer failed, regardless of the arch/platform used and the presence of the IOMMU of the device bus. This patch provides interface to fix this issue.

2016-06-03s5p-mfc: Fix race between s5p_mfc_probe() and s5p_mfc_open()Javier Martinez Canillas1-18/+21
The s5p_mfc_probe() function registers the video devices before all the resources needed by s5p_mfc_open() are correctly initalized. So if s5p_mfc_open() function is called before s5p_mfc_probe() finishes (since the video dev is already registered), a NULL pointer dereference will happen due s5p_mfc_open() accessing uninitialized vars such as the struct s5p_mfc_dev .watchdog_timer and .mfc_ops fields.

2016-06-03s5p-mfc: Set device name for reserved memory region devsJavier Martinez Canillas1-0/+4
The devices don't have a name set, so makes dev_name() returns NULL which makes harder to identify the devices that are causing issues, for example: WARNING: CPU: 2 PID: 616 at drivers/base/core.c:251 device_release+0x8c/0x90 Device '(null)' does not have a release() function, it is broken and must be fixed. And after setting the device name: WARNING: CPU: 0 PID: 591 at drivers/base/core.c:251 device_release+0x8c/0x90 Device 's5p-mfc-l' does not have a release() function, it is broken and must be fixed.
