Follow the commit bfe1326573ff ("venus: Fix for H265 decoding failure.") and increase H265D_MAX_SLICE following firmware requirements on that platform. Otherwise decoding of the H.265 streams fails with the "insufficient scratch_1 buffer size" from the firmware.

2026-04-27media: iris: fix use-after-free of fmt_src during MBPF checkVishnu Reddy5-18/+2
During concurrency testing, multiple instances can run in parallel, and each instance uses its own inst->lock while the core->lock protects the list of active instances. The race happens because these locks cover different scopes, inst->lock protects only the internals of a single instance, while the Macro Blocks Per Frame (MBPF) checker walks the core list under core->lock and reads fields like fmt_src->width and fmt_src->height. At the same time, iris_close() may free fmt_src and fmt_dst under inst->lock while the instance is still present in the core list. This allows a situation where the MBPF checker, still iterating through the core list, reaches an instance whose fmt_src was already freed by another thread and ends up dereferencing a dangling pointer, resulting in a use-after-free. This happens because the MBPF checker assumes that any instance in the core list is fully valid, but the freeing of fmt_src and fmt_dst without removing the instance from the core list is not correct. The correct ordering is to defer freeing fmt_src and fmt_dst until after the instance has been removed from the core list and all teardown under the core lock has completed, ensuring that no dangling pointers are ever exposed during MBPF checks.

2026-04-27media: iris: switch to hardware mode after firmware bootVikash Garodia7-23/+38
Currently the driver switches the vcodec GDSC to hardware (HW) mode before firmware load and boot sequence. GDSC can be powered off, keeping in hw mode, thereby the vcodec registers programmed in TrustZone (TZ) carry default (reset) values. Move the transition to HW mode after firmware load and boot sequence. The bug was exposed with driver configuring different stream ids to different devices via iommu-map. With registers carrying reset values, VPU would not generate desired stream-id, thereby leading to SMMU fault. For vpu4, when GDSC is switched to HW mode, there is a need to perform the reset operation. Without reset, there are occasional issues of register corruption observed. Hence the vpu GDSC switch also involves the reset.

2026-04-27media: iris: Fix use-after-free in iris_release_internal_buffers()Dikshita Agarwal1-2/+4
The recent change in commit 1dabf00ee206 ("media: iris: gen1: Destroy internal buffers after FW releases") introduced a regression where session_release_buf() may free the buffer. The caller, iris_release_internal_buffers(), continued to access `buffer` after the call, leading to a potential use-after-free. Fix this by setting BUF_ATTR_PENDING_RELEASE before calling session_release_buf(), and reverting the flag if the call fails. This ensures no dereference occurs after potential freeing.

Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically.

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, ...)

2026-01-20media: iris: Prevent output buffer queuing before stream-on completesVishnu Reddy1-3/+7
During normal playback, stream-on for input is followed by output, and only after input stream-on does actual streaming begin. However, when gst-play performs a seek, both input and output streams are stopped, and on restart, output stream-on occurs first. At this point, firmware has not yet started streaming. Queuing output buffers before the firmware begins streaming causes it to process buffers in an invalid state, leading to an error response. These buffers are returned to the driver as errors, forcing the driver into an error state and stopping playback. Fix this by deferring output buffer queuing until stream-on completes. Input buffers can still be queued before stream-on as required.

handling Currently v4l2_m2m_ioctl_{de,enc}coder_cmd is being invoked during STOP command handling. However, this is not required as the iris driver has its own drain and stop handling mechanism in place. Using the m2m command API in this context leads to incorrect behavior, where the LAST flag is prematurely attached to a capture buffer, when there are no buffers in m2m source queue. But, in this scenario even though the source buffers are returned to client, hardware might still need to process the pending capture buffers. Attaching LAST flag prematurely can result in the capture buffer being removed from the destination queue before the hardware has finished processing it, causing issues when the buffer is eventually returned by the hardware. To prevent this, remove the m2m API usage in stop handling.

Now that we are at it, mark the fps smaller than 1 as invalid, the code does not seem to handle them properly. The following cocci warning is fixed with this patch: ./platform/qcom/iris/iris_venc.c:378:1-7: WARNING: do_div() does a 64-by-32 division, please consider using div64_u64 instead Fixes: 4ff586ff28e3 ("media: iris: Add support for G/S_PARM for encoder video device") Reviewed-by: Dikshita Agarwal <dikshita.agarwal@oss.qualcomm.com> Cc: stable@vger.kernel.org Signed-off-by: Ricardo Ribalda <ribalda@chromium.org> Signed-off-by: Bryan O'Donoghue <bod@kernel.org> Signed-off-by: Hans Verkuil <hverkuil+cisco@kernel.org>
2026-01-20media: iris: Fix ffmpeg corrupted frame errorVishnu Reddy1-1/+1
When the ffmpeg decoder is running, the driver receives the V4L2_BUF_FLAG_KEYFRAME flag in the input buffer. The driver then forwards this flag information to the firmware. The firmware, in turn, copies the input buffer flags directly into the output buffer flags. Upon receiving the output buffer from the firmware, the driver observes that the buffer contains the HFI_BUFFERFLAG_DATACORRUPT flag. The root cause is that both V4L2_BUF_FLAG_KEYFRAME and HFI_BUFFERFLAG_DATACORRUPT are the same value. As a result, the driver incorrectly interprets the output frame as corrupted, even though the frame is actually valid. This misinterpretation causes the driver to report an error and skip good frames, leading to missing frames in the final video output and triggering ffmpeg's "corrupt decoded frame" error. To resolve this issue, the input buffer flags should not be sent to the firmware during decoding, since the firmware does not require this information.

2026-01-20Revert "media: iris: Add sanity check for stop streaming"Dikshita Agarwal1-5/+3
This reverts commit ad699fa78b59241c9d71a8cafb51525f3dab04d4. Revert the check that skipped stop_streaming when the instance was in IRIS_INST_ERROR, as it caused multiple regressions: 1. Buffers were not returned to vb2 when the instance was already in error state, triggering warnings in the vb2 core because buffer completion was skipped. 2. If a session failed early (e.g. unsupported configuration), the instance transitioned to IRIS_INST_ERROR. When userspace attempted to stop streaming for cleanup, stop_streaming was skipped due to the added check, preventing proper teardown and leaving the firmware in an inconsistent state.

In preparation for making the kmalloc family of allocators type aware, we need to make sure that the returned type from the allocation matches the type of the variable being assigned. (Before, the allocator would always return "void *", which can be implicitly cast to any pointer type.) The assigned type is "struct iris_inst *", but the returned type is "struct iris_inst_hfi_gen2 *". The allocation is intentionally larger as the first member of struct iris_inst_hfi_gen2 is struct iris_inst, so this is by design. Cast the allocation type to match the assignment.

Add sanity check in iris_vb2_stop_streaming. If inst->state is already IRIS_INST_ERROR, we should skip the stream_off operation because it would still send packets to the firmware. In iris_kill_session, inst->state is set to IRIS_INST_ERROR and session_close is executed, which will kfree(inst_hfi_gen2->packet). If stop_streaming is called afterward, it will cause a crash.

2025-11-06media: iris: Refine internal buffer reconfiguration logic for resolution changeDikshita Agarwal1-2/+5
Improve the condition used to determine when input internal buffers need to be reconfigured during streamon on the capture port. Previously, the check relied on the INPUT_PAUSE sub-state, which was also being set during seek operations. This led to input buffers being queued multiple times to the firmware, causing session errors due to duplicate buffer submissions. This change introduces a more accurate check using the FIRST_IPSC and DRC sub-states to ensure that input buffer reconfiguration is triggered only during resolution change scenarios, such as streamoff/on on the capture port. This avoids duplicate buffer queuing during seek operations.
