2023-12-07drm/exynos: fix a wrong error checkingInki Dae
Fix a wrong error checking in exynos_drm_dma.c module. In the exynos_drm_register_dma function, both arm_iommu_create_mapping() and iommu_get_domain_for_dev() functions are expected to return NULL as an error. However, the error checking is performed using the statement if(IS_ERR(mapping)), which doesn't provide a suitable error value. So check if 'mapping' is NULL, and if it is, return -ENODEV. This issue[1] was reported by Dan. Changelog v1: - fix build warning.

2023-12-06drm/atomic-helpers: Invoke end_fb_access while owning plane stateThomas Zimmermann
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

2023-12-05drm/i915: Skip some timing checks on BXT/GLK DSI transcodersVille Syrjälä
Apparently some BXT/GLK systems have DSI panels whose timings don't agree with the normal cpu transcoder hblank>=32 limitation. 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.

So check for that before we go poking at the hardware.

It was noticed when setting the Panfrost's DVFS device to the performant governor, GPU frequency as reported by fdinfo had dropped to 0 permamently. There are two separate issues causing this behaviour: - Not initialising the device's current_frequency variable to its original value during device probe(). - Updating said variable in Panfrost devfreq's get_dev_status() rather than after the new OPP's frequency had been retrieved in target(), which meant the old frequency would be assigned instead.

2023-11-29drm/amd/display: Allow DTBCLK disable for DCN35Nicholas Kazlauskas
[Why] DTBCLK is enabled on idle and it will burn power. [How] There's a few issues here: - Always enabling DTBCLK on clock manager init - Setting refclk when DTBCLK is supposed to be disabled - Not applying the correct calculated version refclk, but instead the base value which might be zero On dtbclk_en change we'll message PMFW to enable or disable the clock accordingly. The DTBDTO will be then based on refclk, but it will be set to the default fixed value if there was nothing calculated in DML despite the clock being considered enabled.

2023-11-29drm/amdgpu: Fix cat debugfs amdgpu_regs_didt causes kernel null pointerLu Yao
For 'AMDGPU_FAMILY_SI' family cards, in 'si_common_early_init' func, init 'didt_rreg' and 'didt_wreg' to 'NULL'. But in func 'amdgpu_debugfs_regs_didt_read/write', using 'RREG32_DIDT' 'WREG32_DIDT' lacks of relevant judgment. And other 'amdgpu_ip_block_version' that use these two definitions won't be added for 'AMDGPU_FAMILY_SI'. So, add null pointer judgment before calling.

2023-11-29drm/amdgpu: fix AGP addressing when GART is not at 0Alex Deucher
This worked by luck if the GART aperture ended up at 0. When we ended up moving GART on some chips, the GART aperture ended up offsetting the AGP address since the resource->start is a GART offset, not an MC address. Fix this by moving the AGP address setup into amdgpu_bo_gpu_offset_no_check(). v2: check mem_type before checking agp v3: check if the ttm bo has a ttm_tt allocated yet Fixes: 67318cb84341 ("drm/amdgpu/gmc11: set gart placement GC11") Tested-by: Mario Limonciello <mario.limonciello@amd.com> Reported-by: Jesse Zhang <Jesse.Zhang@amd.com> Reported-by: Yifan Zhang <yifan1.zhang@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: christian.koenig@amd.com Cc: mario.limonciello@amd.com

2023-11-29drm/amd/display: fix ABM disablementHamza Mahfooz
On recent versions of DMUB firmware, if we want to completely disable ABM we have to pass ABM_LEVEL_IMMEDIATE_DISABLE as the requested ABM level to DMUB. Otherwise, LCD eDP displays are unable to reach their maximum brightness levels. So, to fix this whenever the user requests an ABM level of 0 pass ABM_LEVEL_IMMEDIATE_DISABLE to DMUB instead. Also, to keep the user's experience consistent map ABM_LEVEL_IMMEDIATE_DISABLE to 0 when a user tries to read the requested ABM level.
