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.

Failing to get the struct s5p_mfc_pm .clock is a non-fatal error so the clock field can have a errno pointer value. But s5p_mfc_final_pm() only checks if .clock is not NULL before attempting to unprepare and put it. This leads to the following warning in clk_put() due s5p_mfc_final_pm(): WARNING: CPU: 3 PID: 1023 at drivers/clk/clk.c:2814 s5p_mfc_final_pm+0x48/0x74 [s5p_mfc] CPU: 3 PID: 1023 Comm: rmmod Tainted: G W 4.6.0-rc6-next-20160502-00005-g5a15a49106bc #9 Hardware name: SAMSUNG EXYNOS (Flattened Device Tree) [<c010e1bc>] (unwind_backtrace) from [<c010af28>] (show_stack+0x10/0x14) [<c010af28>] (show_stack) from [<c032485c>] (dump_stack+0x88/0x9c) [<c032485c>] (dump_stack) from [<c011b8e8>] (__warn+0xe8/0x100) [<c011b8e8>] (__warn) from [<c011b9b0>] (warn_slowpath_null+0x20/0x28) [<c011b9b0>] (warn_slowpath_null) from [<bf16004c>] (s5p_mfc_final_pm+0x48/0x74 [s5p_mfc]) [<bf16004c>] (s5p_mfc_final_pm [s5p_mfc]) from [<bf157414>] (s5p_mfc_remove+0x8c/0x94 [s5p_mfc]) [<bf157414>] (s5p_mfc_remove [s5p_mfc]) from [<c03fe1f8>] (platform_drv_remove+0x24/0x3c) [<c03fe1f8>] (platform_drv_remove) from [<c03fcc70>] (__device_release_driver+0x84/0x110) [<c03fcc70>] (__device_release_driver) from [<c03fcdd8>] (driver_detach+0xac/0xb0) [<c03fcdd8>] (driver_detach) from [<c03fbff8>] (bus_remove_driver+0x4c/0xa0) [<c03fbff8>] (bus_remove_driver) from [<c01886a8>] (SyS_delete_module+0x174/0x1b8) [<c01886a8>] (SyS_delete_module) from [<c01078c0>] (ret_fast_syscall+0x0/0x3c) Assign the pointer to NULL in case of a lookup failure to fix the issue.

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). Signed-off-by:

This patch removes custom code for initialization and handling of reserved memory regions in s5p-mfc driver and replaces it with generic reserved memory regions api. s5p-mfc driver now handles two reserved memory regions defined by generic reserved memory bindings. Support for non-dt platform has been removed, because all supported platforms have been already converted to device tree. Signed-off-by:

Marek Szyprowski authored
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. Signed-off-by:
