2025-07-29drm/xe/hw_engine_group: Don't use drm_warn to catch missed caseMichal Wajdeczko1-2/+2
Since hwe->class is an enumeration we can rely on the compiler to catch any unhandled engine class case at compile time thanks to [-Werror=switch]. Any unexpected use of a special CLASS_MAX enum case can be guarded by our xe_gt_assert() instead, which will be compiled-out on the production builds.

2025-07-28drm/xe/guc: Add more GuC load error status codesJohn Harrison2-2/+20
The GuC load process will abort if certain status codes (which are indicative of a fatal error) are reported. Otherwise, it keeps waiting until the 'success' code is returned. New error codes have been added in recent GuC releases, so add support for aborting on those as well. v2: Shuffle HWCONFIG_START to the front of the switch to keep the ordering as per the enum define for clarity (review feedback by Jonathan). Also add a description for the basic 'invalid init data' code which was missing.

git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs Pull mmap_prepare updates from Christian Brauner: "Last cycle we introduce f_op->mmap_prepare() in c84bf6dd2b83 ("mm: introduce new .mmap_prepare() file callback"). This is preferred to the existing f_op->mmap() hook as it does require a VMA to be established yet, thus allowing the mmap logic to invoke this hook far, far earlier, prior to inserting a VMA into the virtual address space, or performing any other heavy handed operations. This allows for much simpler unwinding on error, and for there to be a single attempt at merging a VMA rather than having to possibly reattempt a merge based on potentially altered VMA state. Far more importantly, it prevents inappropriate manipulation of incompletely initialised VMA state, which is something that has been the cause of bugs and complexity in the past. The intent is to gradually deprecate f_op->mmap, and in that vein this series coverts the majority of file systems to using f_op->mmap_prepare. Prerequisite steps are taken - firstly ensuring all checks for mmap capabilities use the file_has_valid_mmap_hooks() helper rather than directly checking for f_op->mmap (which is now not a valid check) and secondly updating daxdev_mapping_supported() to not require a VMA parameter to allow ext4 and xfs to be converted. Commit bb666b7c2707 ("mm: add mmap_prepare() compatibility layer for nested file systems") handles the nasty edge-case of nested file systems like overlayfs, which introduces a compatibility shim to allow f_op->mmap_prepare() to be invoked from an f_op->mmap() callback. This allows for nested filesystems to continue to function correctly with all file systems regardless of which callback is used. Once we finally convert all file systems, this shim can be removed. As a result, ecryptfs, fuse, and overlayfs remain unaltered so they can nest all other file systems. We additionally do not update resctl - as this requires an update to remap_pfn_range() (or an alternative to it) which we defer to a later series, equally we do not update cramfs which needs a mixed mapping insertion with the same issue, nor do we update procfs, hugetlbfs, syfs or kernfs all of which require VMAs for internal state and hooks.

2025-07-28drm/amd/display: Move setup_stream_attributeMichael Strauss5-3/+12
[WHY] If symclk RCO is enabled, stream encoder may not be receiving an ungated clock by the time we attempt to set stream attributes when setting dpms on. Since the clock is gated, register writes to the stream encoder fail. [HOW] Move set_stream_attribute call into enable_stream, just after the point where symclk32_se is ungated. Logically there is no need to set stream attributes as early as is currently done in link_set_dpms_on, so this should have no impact beyond the RCO fix.

2025-07-28drm/amd/display: Reduce Stack Usage by moving 'audio_output' into ↵Srinivasan Shanmugam5-31/+26
'stream_res' v4 The function `dp_retrain_link_dp_test` currently allocates a large audio_output array on the stack, causing the stack frame size to exceed the compiler limit (1080 bytes > 1024 bytes). This change prevents stack overflow issues: amdgpu/../display/dc/link/accessories/link_dp_cts.c:65:13: warning: stack frame size (1080) exceeds limit (1024) in 'dp_retrain_link_dp_test' [-Wframe-larger-than] static void dp_retrain_link_dp_test(struct dc_link *link, v2: Move audio-related data like `audio_output` is kept "per pipe" to manage the audio for that specific display pipeline/display output path (stream). (Wenjing) v3: Update in all the places where `build_audio_output` is currently called with a separate audio_output variable on the stack & wherever `audio_output` is passed to other functions `dce110_apply_single_controller_ctx_to_hw()` & `dce110_setup_audio_dto()` (like `az_configure`, `wall_dto_setup`) replace with usage of `pipe_ctx->stream_res.audio_output` to centralize audio data per pipe. v4: Remove empty lines before `build_audio_output`.
