media: mediatek: jpeg: support 34bits

2025-05-15T06:13:31Z

The HW iommu is able to support a 34-bit iova address-space (16GB), enable this feature for the encoder/decoder driver by shifting the address by two bits and setting the extended address registers.

media: mediatek: vcodec: Enable HEVC main still picture decode

2025-04-24T13:21:34Z

Mediatek devices that support HEVC also support the main still picture profile, but today, the main still picture profile is excluded. This removes the skip mask for HEVC, and enables the main still picture profile decoding.

media: mediatek: vcodec: add description for vsi struct

2025-04-11T11:21:14Z

The vsi (video shared information) struct needs to be synchronized between firmware and host, as a change that is only done in the host version of the struct but isn't synchronized to the firmware. This can lead to decoding issues with H264 bitstreams. Highlight this requirement within the struct descriptions.

media: mediatek: vcodec: support extended h264 decode

2025-04-11T11:21:13Z

Add a new extended vsi_ext struct besides the existing vsi struct, to enable calculating the end of the address range of the current working buffer for architectures, where simply adding the buffer size to the start of the address range isn't sufficient. Additionally, on extended architectures, the NAL information can be fetched directly from the firmware, which allows skipping the parsing step within the kernel.

media: mediatek: vcodec: remove vsi operation in common interface

2025-04-11T11:21:12Z

Extend the VSI (video shared information) struct to allow sending slice parameters to SCP, as the parameters have changed on MT8188 architecture. Remove VSI related information from the common interface to ensure that the interface is usable by architectures with and without the extended parameters. The new VSI extensions will be introduced in later patches.

media: mediatek: vcodec: Correct vsi_core framebuffer size

2025-04-11T11:21:12Z

The framebuffer size for decoder instances was being incorrectly set - inst->vsi_core->fb.y.size was assigned twice consecutively. Assign the second picinfo framebuffer size to the C framebuffer instead, which appears to be the intended target based on the surrounding code.

2025-02-21T09:33:02Z

On Mediatek devices with a system companion processor (SCP) the mtk_scp structure has to be removed explicitly to avoid a resource leak. Free the structure in case the allocation of the firmware structure fails during the firmware initialization.
