We initially introduced a spin lock to ensure that the VPU registers are not accessed concurrently between our setup function and IRQ handler. The V4L2 M2M API ensures that only one decoding job runs at a time, so the interrupt signaling the end of decoding will not occur while the next picture is being configured. Spurious interrupts are taken care of in the handler, by checking that we have a valid M2M context and a decoding status available before marking the buffers as done. In addition, holding a spin lock could be problematic if non-atomic operations are required in the setup process for future codec support. As a result, remove the global IRQ spin lock. Signed-off-by:

Add support for the third loop filter mode V4L2_MPEG_VIDEO_H264_LOOP_FILTER_MODE_DISABLED_AT_SLICE_BOUNDARY, and fix V4L2_CID_MPEG_VIDEO_H264_LOOP_FILTER_ALPHA and V4L2_CID_MPEG_VIDEO_H264_LOOP_FILTER_BETA controls. The filter offset controls are signed values in the -6 to 6 range and are stored into the slice header fields slice_alpha_c0_offset_div2 and slice_beta_offset_div2. The actual filter offsets FilterOffsetA/B are double their value, in range of -12 to 12. Rename variables to more closely match the nomenclature in the H.264 specification. Signed-off-by:

The venus and s5p-mfc drivers add the loop filter alpha/beta offset controls V4L2_CID_MPEG_VIDEO_H264_LOOP_FILTER_ALPHA/BETA with a range of -6 to +6, inclusive. This is exactly the range specified for the slice header fields slice_alpha_c0_offset_div2 and slice_beta_offset_div2, which store half the actual filter offsets FilterOffsetA/B. Clarify that this control contains the halved offsets. Signed-off-by:

The GNU Free Documentation License allows for a work to specify Invariant Sections that are not allowed to be modified. (Debian considers that this makes such works non-free.) The Linux Media Infrastructure userspace API documentation does not specify any such sections, but it also doesn't say there are none (as is recommended by the license text). Make it explicit that there are none. Signed-off-by:

The clock rate, while hardcoded until now, is actually a function of the resolution, framerate and bytes per pixel. Now that we have an algorithm to adjust our clock rate, we can select it dynamically when we change the mode. This changes a bit the clock rate being used, with the following effect: +------+------+------+------+-----+-----------------+----------------+-----------+ | Hact | Vact | Htot | Vtot | FPS | Hardcoded clock | Computed clock | Deviation | +------+------+------+------+-----+-----------------+----------------+-----------+ | 640 | 480 | 1896 | 1080 | 15 | 56000000 | 61430400 | 8.84 % | | 640 | 480 | 1896 | 1080 | 30 | 112000000 | 122860800 | 8.84 % | | 1024 | 768 | 1896 | 1080 | 15 | 56000000 | 61430400 | 8.84 % | | 1024 | 768 | 1896 | 1080 | 30 | 112000000 | 122860800 | 8.84 % | | 320 | 240 | 1896 | 984 | 15 | 56000000 | 55969920 | 0.05 % | | 320 | 240 | 1896 | 984 | 30 | 112000000 | 111939840 | 0.05 % | | 176 | 144 | 1896 | 984 | 15 | 56000000 | 55969920 | 0.05 % | | 176 | 144 | 1896 | 984 | 30 | 112000000 | 111939840 | 0.05 % | | 720 | 480 | 1896 | 984 | 15 | 56000000 | 55969920 | 0.05 % | | 720 | 480 | 1896 | 984 | 30 | 112000000 | 111939840 | 0.05 % | | 720 | 576 | 1896 | 984 | 15 | 56000000 | 55969920 | 0.05 % | | 720 | 576 | 1896 | 984 | 30 | 112000000 | 111939840 | 0.05 % | | 1280 | 720 | 1892 | 740 | 15 | 42000000 | 42002400 | 0.01 % | | 1280 | 720 | 1892 | 740 | 30 | 84000000 | 84004800 | 0.01 % | | 1920 | 1080 | 2500 | 1120 | 15 | 84000000 | 84000000 | 0.00 % | | 1920 | 1080 | 2500 | 1120 | 30 | 168000000 | 168000000 | 0.00 % | | 2592 | 1944 | 2844 | 1944 | 15 | 84000000 | 165862080 | 49.36 % | +------+------+------+------+-----+-----------------+----------------+-----------+ Only the 640x480, 1024x768 and 2592x1944 modes are significantly affected by the new formula. In this case, 640x480 and 1024x768 are actually fixed by this change. Indeed, the sensor was sending data at, for example, 27.33fps instead of 30fps. This is -9%, which is roughly what we're seeing in the array. Testing these modes with the new clock setup actually fix that error, and data are now sent at around 30fps. 2592x1944, on the other hand, is probably due to the fact that this mode can only be used using MIPI-CSI2, in a two lane mode, and never really tested with a DVP bus.
