| | * drm/atomic-helpers: Invoke end_fb_access while owning plane stateThomas Zimmermann2023-12-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Invoke drm_plane_helper_funcs.end_fb_access before drm_atomic_helper_commit_hw_done(). The latter function hands over ownership of the plane state to the following commit, which might free it. Releasing resources in end_fb_access then operates on undefined state. This bug has been observed with non-blocking commits when they are being queued up quickly. Here is an example stack trace from the bug report. The plane state has been free'd already, so the pages for drm_gem_fb_vunmap() are gone. Unable to handle kernel paging request at virtual address 0000000100000049 [...] drm_gem_fb_vunmap+0x18/0x74 drm_gem_end_shadow_fb_access+0x1c/0x2c drm_atomic_helper_cleanup_planes+0x58/0xd8 drm_atomic_helper_commit_tail+0x90/0xa0 commit_tail+0x15c/0x188 commit_work+0x14/0x20 Fix this by running end_fb_access immediately after updating all planes in drm_atomic_helper_commit_planes(). The existing clean-up helper drm_atomic_helper_cleanup_planes() now only handles cleanup_fb. For aborted commits, roll back from drm_atomic_helper_prepare_planes() in the new helper drm_atomic_helper_unprepare_planes(). This case is different from regular cleanup, as we have to release the new state; regular cleanup releases the old state. The new helper also invokes cleanup_fb for all planes. The changes mostly involve DRM's atomic helpers. Only two drivers, i915 and nouveau, implement their own commit function. Update them to invoke drm_atomic_helper_unprepare_planes(). Drivers with custom commit_tail function do not require changes. v4: * fix documentation (kernel test robot) v3: * add drm_atomic_helper_unprepare_planes() for rolling back * use correct state for end_fb_access v2: * fix test in drm_atomic_helper_cleanup_planes() Reported-by: Alyssa Ross <hi@alyssa.is> Closes: https://lore.kernel.org/dri-devel/87leazm0ya.fsf@alyssa.is/ Suggested-by: Daniel Vetter <daniel@ffwll.ch> Fixes: 94d879eaf7fb ("drm/atomic-helper: Add {begin,end}_fb_access to plane helpers") Tested-by: Alyssa Ross <hi@alyssa.is> Reviewed-by: Alyssa Ross <hi@alyssa.is> Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Cc: <stable@vger.kernel.org> # v6.2+ Link: https://patchwork.freedesktop.org/patch/msgid/20231204083247.22006-1-tzimmermann@suse.de

| * | drm/i915: Skip some timing checks on BXT/GLK DSI transcodersVille Syrjälä2023-12-0512-3/+79

This is perhaps fine as there are no specific hblank/etc. limits listed for the BXT/GLK DSI transcoders. Move those checks out from the global intel_mode_valid() into into connector specific .mode_valid() hooks, skipping BXT/GLK DSI connectors. We'll leave the basic [hv]display/[hv]total checks in intel_mode_valid() as those seem like sensible upper limits regardless of the transcoder used.

| * | drm/i915: Check pipe active state in {planes,vrr}_{enabling,disabling}()Ville Syrjälä2023-12-011-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | {planes,vrr}_{enabling,disabling}() are supposed to indicate whether the specific hardware feature is supposed to be enabling or disabling. That can only makes sense if the pipe is active overall. So check for that before we go poking at the hardware. I think we're semi-safe currently on due to: - intel_pre_plane_update() doesn't get called when the pipe was not-active prior to the commit, but this is actually a bug. This saves vrr_disabling(), and vrr_enabling() is called from deeper down where we have already checked hw.active. - active_planes mirrors the crtc's hw.active Reviewed-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20231121054324.9988-2-ville.syrjala@linux.intel.com (cherry picked from commit bc53c4d56eb24dbe56cd2c66ef4e9fc9393b1533) Signed-off-by: Jani Nikula <jani.nikula@intel.com>

On that board eDP/DDI-A has its HPD asserted despite nothing being actually connected there :( The straps/fuses also indicate that the eDP port is present. So if one boots with a VGA monitor connected the eDP probe will mistake the DP->VGA converter hooked to DDI-E for an eDP panel on DDI-A. As a last resort check what kind of DP device we've detected, and if it looks like a DP->VGA converter then conclude that the eDP port should be ignored.

However, the trace logs use the uabi class and instance to identify the engine, so leaving uabi class unset makes the GSC CS show up as the RCS in those logs. Given that the engine is not exposed to the user, we can't add a new case in the uabi enum, so we insted internally define a kernel internal class as -1. At the same time remove special handling for the name and complete the uabi_classes array so internal class is automatically correctly assigned. Engine will show as 65535:0 other0 in the logs/traces which should be unique enough. v2: * Fix uabi class u8 vs u16 type confusion.

To handle this, split the spin_lock/unlock_irqsave/restore() into spin_lock/unlock() followed by a call to local_irq_save/restore() and create wrapper functions for locking and unlocking the uncore's spinlock. In these functions, we have a condition check and only actually try to lock/unlock the spinlock when I915 is defined, and thus uncore is available. This keeps the ifdefs contained in these new functions and all such logic inside the display code.

But that is not the case if the original fb stride exceeds the aligned stride used to populate the remapped view, which is calculated from the user specified framebuffer width rather than the user specified framebuffer stride. Ignore the original fb stride in this case and just stick to the POT aligned stride. Getting this wrong will cause the plane to fetch the wrong data, and can lead to fault errors if the page tables at the bogus location aren't even populated. TODO: figure out if this is OK for CCS, or if we should instead increase the width of the view to cover the entire user specified fb stride instead...

| * | | drm/i915: do not clean GT table on error pathAndrzej Hajda2023-11-202-14/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only task of intel_gt_release_all is to zero gt table. Calling it on error path prevents intel_gt_driver_late_release_all (called from i915_driver_late_release) to cleanup GTs, causing leakage. After i915_driver_late_release GT array is not used anymore so it does not need cleaning at all. Sample leak report: BUG i915_request (...): Objects remaining in i915_request on __kmem_cache_shutdown() ...
