2023-08-24drm/nouveau: uapi: don't pass NO_PREFETCH flag implicitlyDanilo Krummrich
Currently, NO_PREFETCH is passed implicitly through drm_nouveau_gem_pushbuf_push::length and drm_nouveau_exec_push::va_len. Since this is a direct representation of how the HW is programmed it isn't really future proof for a uAPI. Hence, fix this up for the new uAPI and split up the va_len field of struct drm_nouveau_exec_push, such that we keep 32bit for va_len and 32bit for flags. For drm_nouveau_gem_pushbuf_push::length at least provide NOUVEAU_GEM_PUSHBUF_NO_PREFETCH to indicate the bit shift. While at it, fix up nv50_dma_push() as well, such that the caller doesn't need to encode the NO_PREFETCH flag into the length parameter.

2023-08-24drm/nouveau: sched: avoid job races between entitiesDanilo Krummrich
If a sched job depends on a dma-fence from a job from the same GPU scheduler instance, but a different scheduler entity, the GPU scheduler does only wait for the particular job to be scheduled, rather than for the job to fully complete. This is due to the GPU scheduler assuming that there is a scheduler instance per ring. However, the current implementation, in order to avoid arbitrary amounts of kthreads, has a single scheduler instance while scheduler entities represent rings. As a workaround, set the DRM_SCHED_FENCE_DONT_PIPELINE for all out-fences in order to force the scheduler to wait for full job completion for dependent jobs from different entities and same scheduler instance. There is some work in progress [1] to address the issues of firmware schedulers; once it is in-tree the scheduler topology in Nouveau should be re-worked accordingly.

2023-08-23drm/i915: Fix HPD polling, reenabling the output poll work as neededImre Deak
After the commit in the Fixes: line below, HPD polling stopped working on i915, since after that change calling drm_kms_helper_poll_enable() doesn't restart drm_mode_config::output_poll_work if the work was stopped (no connectors needing polling) and enabling polling for a connector (during runtime suspend or detecting an HPD IRQ storm). After the above change calling drm_kms_helper_poll_enable() is a nop after it's been called already and polling for some connectors was disabled/re-enabled. Fix this by calling drm_kms_helper_poll_reschedule() added in the previous patch instead, which reschedules the work whenever expected.

2023-08-23drm/vmwgfx: Fix possible invalid drm gem put callsZack Rusin
vmw_bo_unreference sets the input buffer to null on exit, resulting in null ptr deref's on the subsequent drm gem put calls. This went unnoticed because only very old userspace would be exercising those paths but it wouldn't be hard to hit on old distros with brand new kernels.

2023-08-22clk: Annotate struct clk_hw_onecell_data with __counted_byKees Cook
Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct clk_hw_onecell_data. Additionally, since the element count member must be set before accessing the annotated flexible array member, move its initialization earlier.

2023-08-18drm: bridge: samsung-dsim: Fix init during host transferFrieder Schrempf
In case the downstream bridge or panel uses DSI transfers before the DSI host was actually initialized through samsung_dsim_atomic_enable() which clears the stop state (LP11) mode, all transfers will fail. This happens with downstream bridges that are controlled by DSI commands such as the tc358762. As documented in [1] DSI hosts are expected to allow transfers outside the normal bridge enable/disable flow. To fix this make sure that stop state is cleared in samsung_dsim_host_transfer() which restores the previous behavior. We also factor out the common code to enable/disable stop state to samsung_dsim_set_stop_state().

2023-08-18drm/qxl: fix UAF on handle creationWander Lairson Costa
qxl_mode_dumb_create() dereferences the qobj returned by qxl_gem_object_create_with_handle(), but the handle is the only one holding a reference to it. A potential attacker could guess the returned handle value and closes it between the return of qxl_gem_object_create_with_handle() and the qobj usage, triggering a use-after-free scenario. Reproducer: int dri_fd =-1; struct drm_mode_create_dumb arg = {0}; void gem_close(int handle); void* trigger(void* ptr) { int ret; arg.width = arg.height = 0x20; arg.bpp = 32; ret = ioctl(dri_fd, DRM_IOCTL_MODE_CREATE_DUMB, &arg); if(ret) { perror("[*] DRM_IOCTL_MODE_CREATE_DUMB Failed"); exit(-1); } gem_close(arg.handle); while(1) { struct drm_mode_create_dumb args = {0}; args.width = args.height = 0x20; args.bpp = 32; ret = ioctl(dri_fd, DRM_IOCTL_MODE_CREATE_DUMB, &args); if (ret) { perror("[*] DRM_IOCTL_MODE_CREATE_DUMB Failed"); exit(-1); } printf("[*] DRM_IOCTL_MODE_CREATE_DUMB created, %d\n", args.handle); gem_close(args.handle); } return NULL; } void gem_close(int handle) { struct drm_gem_close args; args.handle = handle; int ret = ioctl(dri_fd, DRM_IOCTL_GEM_CLOSE, &args); // gem close handle if (!ret) printf("gem close handle %d\n", args.handle); } int main(void) { dri_fd= open("/dev/dri/card0", O_RDWR); printf("fd:%d\n", dri_fd); if(dri_fd == -1) return -1; pthread_t tid1; if(pthread_create(&tid1,NULL,trigger,NULL)){ perror("[*] thread_create tid1\n"); return -1; } while (1) { gem_close(arg.handle); } return 0; } This is a KASAN report:

due to kernel taint Instead of returning a weak reference to the qxl_bo object, return the created drm_gem_object and let the caller decrement the reference count when it no longer needs it. As a convenience, if the caller is not interested in the gobj object, it can pass NULL to the parameter and the reference counting is descremented internally.

2023-08-17Revert "drm/edid: Fix csync detailed mode parsing"Jani Nikula
This reverts commit ca62297b2085b5b3168bd891ca24862242c635a1. Commit ca62297b2085 ("drm/edid: Fix csync detailed mode parsing") fixed EDID detailed mode sync parsing. Unfortunately, there are quite a few displays out there that have bogus (zero) sync field that are broken by the change. Zero means analog composite sync, which is not right for digital displays, and the modes get rejected. Regardless, it used to work, and it needs to continue to work. Revert the change. Rejecting modes with analog composite sync was the part that fixed the gitlab issue 8146 [1]. We'll need to get back to the drawing board with that.

nouveau_connector_create We can't simply free the connector after calling drm_connector_init on it. We need to clean up the drm side first. It might not fix all regressions from commit 2b5d1c29f6c4 ("drm/nouveau/disp: PIOR DP uses GPIO for HPD, not PMGR AUX interrupts"), but at least it fixes a memory corruption in error handling related to that commit.

This reverts commit 27dd79c00aeab36cd7542c7a4481a32549038659. It appears MPC_SPLIT_DYNAMIC still causes problems with multiple displays on DCN2.0 hardware. Switch back to MPC_SPLIT_AVOID_MULT_DISP. This increases power usage with multiple displays, but avoids hangs.

2023-08-16drm/amd: flush any delayed gfxoff on suspend entryMario Limonciello
DCN 3.1.4 is reported to hang on s2idle entry if graphics activity is happening during entry. This is because GFXOFF was scheduled as delayed but RLC gets disabled in s2idle entry sequence which will hang GFX IP if not already in GFXOFF. To help this problem, flush any delayed work for GFXOFF early in s2idle entry sequence to ensure that it's off when RLC is changed. commit 4b31b92b143f ("drm/amdgpu: complete gfxoff allow signal during suspend without delay") modified power gating flow so that if called in s0ix that it ensured that GFXOFF wasn't put in work queue but instead processed immediately. This is dead code due to commit 10cb67eb8a1b ("drm/amdgpu: skip CG/PG for gfx during S0ix") because GFXOFF will now not be explicitly called as part of the suspend entry code. Remove that dead code.

2023-08-16drm/amdgpu: skip xcp drm device allocation when out of drm resourceJames Zhu
Return 0 when drm device alloc failed with -ENOSPC in order to allow amdgpu drive loading. But the xcp without drm device node assigned won't be visiable in user space. This helps amdgpu driver loading on system which has more than 64 nodes, the current limitation. The proposal to add more drm nodes is discussed in public, which will support up to 2^20 nodes totally. kernel drm: https://lore.kernel.org/lkml/20230724211428.3831636-1-michal.winiarski@intel.com/T/ libdrm: https://gitlab.freedesktop.org/mesa/drm/-/merge_requests/305 Signed-off-by: James Zhu <James.Zhu@amd.com> Acked-by: Christian König <christian.koenig@amd.com> Reviewed-by: Felix Kuehling <Felix.Kuehling@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
