media: qcom: venus: relax encoder frame/blur step size on v6

2026-07-24T13:51:31+00:00

[ Upstream commit c53e0550288b2e08b984b24035c471941b7820c7 ] Encoder HFI capabilities on v6 enforce a 16-pixel step for frame and blur dimensions, which does not reflect actual hardware requirements and can reject valid userspace configurations. Relax the step size to 1 while leaving min/max limits unchanged.

media: qcom: venus: relax encoder frame/blur dimension steps on v4

2026-07-24T13:51:31+00:00

[ Upstream commit 35428ae3a6a40912f1f7b47bb6c65f1a63d0b8f8 ] Encoder HFI capabilities on v4 advertise a 16-pixel step for frame and blur dimensions. This is overly restrictive and can cause userspace caps negotiation to fail even for valid resolutions. Relax the advertised step size to 1 and keep alignment enforcement in buffer layout and size calculations.

media: qcom: venus: drop extra padding in NV12 raw size calculation

2026-07-24T13:51:31+00:00

[ Upstream commit e1c9adabb268cc5d56723b7df1da49e59070f309 ] get_framesize_raw_nv12() currently adds SZ_4K to the UV plane size and an additional SZ_8K to the total buffer size. This inflates the calculated sizeimage and leads userspace to over-allocate buffers without a clear requirement. Remove the extra SZ_4K/SZ_8K padding and compute the NV12 size as the sum of Y and UV planes, keeping the final ALIGN(size, SZ_4K) intact.

media: rockchip: rga: fix too small buffer size

2026-07-24T13:51:29+00:00

[ Upstream commit 65017e26c065d1240b0512c15867ef1128034fd8 ] Fix the command buffer size being only a quarter of the actual size. The RGA_CMDBUF_SIZE macro was potentially intended to specify the length of the cmdbuf u32 array pointer. But as it's used to specify the size of the allocation, which is counted in bytes. Therefore adjust the macro size to bytes as it better matches the variable name and adjust it's users accordingly. As the command buffer is relatively small, it probably didn't caused an issue due to being smaller than a single page.

media: venus: vdec: fix error state assignment for zero bytesused

2026-03-04T12:20:30+00:00

[ Upstream commit 93ecd6ee95c38cb533fa25f48d3c1c8cb69f410f ] When hfi_session_flush is issued, all queued buffers are returned to the V4L2 driver. Some of these buffers are not processed and have bytesused = 0. Currently, the driver marks such buffers as error even during drain operations, which can incorrectly flag EOS buffers. Only capture buffers with zero payload (and not EOS) should be marked with VB2_BUF_STATE_ERROR. The check is performed inside the non-EOS branch to ensure correct handling.
