media: vde: Explicitly specify PMC instance to use

2026-05-28T20:46:35+00:00

Currently the kernel relies on a global variable to reference the PMC context. Use an explicit lookup for the PMC and pass that to the public PMC APIs. Acked-by: Jon Hunter Signed-off-by: Thierry Reding

media: tegra-vde: Add HAS_IOMEM dependency to match SRAM select

2026-05-06T07:05:56+00:00

kconfiglint reports: K002: config VIDEO_TEGRA_VDE selects visible symbol SRAM which has dependencies VIDEO_TEGRA_VDE selects SRAM, which is defined in drivers/misc/Kconfig as: config SRAM bool "Generic on-chip SRAM driver" depends on HAS_IOMEM The NVIDIA Tegra video decoder driver was originally introduced in commit cd6c56feb591 ("media: staging: media: Introduce NVIDIA Tegra video decoder driver") as a staging driver with `depends on ARCH_TEGRA || COMPILE_TEST` and `select SRAM`. Since all Tegra SoCs have HAS_IOMEM, the SRAM dependency was implicitly satisfied for real hardware configurations. The driver was later de-staged in commit 8bd4aaf438e3 ("media: staging: tegra-vde: De-stage driver") and relocated to drivers/media/platform/nvidia/tegra-vde/ in commit 9b18ef7c9ff4 ("media: platform: rename tegra/vde/ to nvidia/tegra-vde/"). Throughout these moves, the `select SRAM` remained without a corresponding HAS_IOMEM dependency. Under COMPILE_TEST on a hypothetical architecture without HAS_IOMEM (such as UML in some configurations), the select would force SRAM on without its HAS_IOMEM dependency being met. Add an explicit `depends on HAS_IOMEM` to make the dependency chain complete and prevent this misconfiguration under COMPILE_TEST.

Convert 'alloc_flex' family to use the new default GFP_KERNEL argument

2026-02-22T01:09:51+00:00

This is the exact same thing as the 'alloc_obj()' version, only much smaller because there are a lot fewer users of the *alloc_flex() interface. As with alloc_obj() version, this was done entirely with mindless brute force, using the same script, except using 'flex' in the pattern rather than 'objs*'. Signed-off-by: Linus Torvalds

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

media: v4l2-mem2mem: Don't copy frame flags in v4l2_m2m_buf_copy_metadata()

2025-10-17T09:31:16+00:00

The v4l2_m2m_buf_copy_metadata() function takes a boolean copy_frame_flags argument. When true, it causes the function to copy the V4L2_BUF_FLAG_KEYFRAME, V4L2_BUF_FLAG_BFRAME and V4L2_BUF_FLAG_PFRAME flags from the output buffer to the capture buffer. There is no use cases in any upstream driver for copying the flags. KEY/P/B frames are properties of the bitstream buffer in some formats. Once decoded, this is no longer a property of the video frame and should be discarded. It was considered useful to know if an uncompressed frame was decoded from a KEY/P/B compressed frame, and to preserve that information if that same uncompressed frame was passed through another M2M device (e.g. a scaler). However, the V4L2 documentation makes it clear that the flags are meant for compressed frames only. Drop the copy_frame_flags argument from v4l2_m2m_buf_copy_metadata(). The change to drivers was performed with the following Coccinelle semantic patch: @@ expression src; expression dst; expression flag; @@ - v4l2_m2m_buf_copy_metadata(src, dst, flag); + v4l2_m2m_buf_copy_metadata(src, dst); include/media/v4l2-mem2mem.h and drivers/media/v4l2-core/v4l2-mem2mem.c have been updated manually.
