2023-05-11drm/amdgpu/gfx: disable gfx9 cp_ecc_error_irq only when enabling legacy gfx rasGuchun Chen
gfx9 cp_ecc_error_irq is only enabled when legacy gfx ras is assert.

2023-05-11drm/i915: taint kernel when force probing unsupported devicesJani Nikula
For development and testing purposes, the i915.force_probe module parameter and DRM_I915_FORCE_PROBE kconfig option allow probing of devices that aren't supported by the driver. The i915.force_probe module parameter is "unsafe" and setting it taints the kernel. However, using the kconfig option does not. Always taint the kernel when force probing a device that is not supported. v2: Drop "depends on EXPERT" to avoid build breakage (kernel test robot) Fixes: 7ef5ef5cdead ("drm/i915: add force_probe module parameter to replace alpha_support") Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Dave Airlie <airlied@gmail.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230504103508.1818540-1-jani.nikula@intel.com (cherry picked from commit 3312bb4ad09ca6423bd4a5b15a94588a8962fb8e) Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com>

2023-05-11drm: sun4i_tcon: use devm_clk_get_enabled in `sun4i_tcon_init_clocks`XuDong Liu
Smatch reports: drivers/gpu/drm/sun4i/sun4i_tcon.c:805 sun4i_tcon_init_clocks() warn: 'tcon->clk' from clk_prepare_enable() not released on lines: 792,801. In the function sun4i_tcon_init_clocks(), tcon->clk and tcon->sclk0 are not disabled in the error handling, which affects the release of these variable. Although sun4i_tcon_bind(), which calls sun4i_tcon_init_clocks(), use sun4i_tcon_free_clocks to disable the variables mentioned, but the error handling branch of sun4i_tcon_init_clocks() ignores the required disable process. To fix this issue, use the devm_clk_get_enabled to automatically balance enable and disabled calls. As original implementation use sun4i_tcon_free_clocks() to disable clk explicitly, we delete the related calls and error handling that are no longer needed.

2023-05-10drm/sched: Check scheduler work queue before calling timeout handlingVitaly Prosyak
During an IGT GPU reset test we see again oops despite of commit 0c8c901aaaebc9 (drm/sched: Check scheduler ready before calling timeout handling). It uses ready condition whether to call drm_sched_fault which unwind the TDR leads to GPU reset. However it looks the ready condition is overloaded with other meanings, for example, for the following stack is related GPU reset : 0 gfx_v9_0_cp_gfx_start 1 gfx_v9_0_cp_gfx_resume 2 gfx_v9_0_cp_resume 3 gfx_v9_0_hw_init 4 gfx_v9_0_resume 5 amdgpu_device_ip_resume_phase2 does the following: /* start the ring */ gfx_v9_0_cp_gfx_start(adev); ring->sched.ready = true; The same approach is for other ASICs as well : gfx_v8_0_cp_gfx_resume gfx_v10_0_kiq_resume, etc... As a result, our GPU reset test causes GPU fault which calls unconditionally gfx_v9_0_fault and then drm_sched_fault. However now it depends on whether the interrupt service routine drm_sched_fault is executed after gfx_v9_0_cp_gfx_start is completed which sets the ready field of the scheduler to true even for uninitialized schedulers and causes oops vs no fault or when ISR drm_sched_fault is completed prior gfx_v9_0_cp_gfx_start and NULL pointer dereference does not occur. Use the field timeout_wq to prevent oops for uninitialized schedulers. The field could be initialized by the work queue of resetting the domain. v1: Corrections to commit message (Luben) Fixes: 11b3b9f461c5c4 ("drm/sched: Check scheduler ready before calling timeout handling") Signed-off-by: Vitaly Prosyak <vitaly.prosyak@amd.com> Link: https://lore.kernel.org/r/20230510135111.58631-1-vitaly.prosyak@amd.com Reviewed-by: Luben Tuikov <luben.tuikov@amd.com> Signed-off-by: Luben Tuikov <luben.tuikov@amd.com>

2023-05-10drm: sun4i: rename sun4i_dotclock to sun4i_tcon_dclkRoman Beranek
While the rate of TCON0's DCLK matches dotclock for parallel and LVDS outputs, this doesn't hold for DSI. The 'D' in DCLK actually stands for 'Data' according to Allwinner's manuals. The clock is mostly referred to as dclk throughout this driver already anyway, so stick with that.

2023-05-05drm/i915/uc: Reject duplicate entries in firmware tableJohn Harrison
It was noticed that duplicate entries in the firmware table could cause an infinite loop in the firmware loading code if that entry failed to load. Duplicate entries are a bug anyway and so should never happen. Ensure they don't by tweaking the table validation code to reject duplicates. For full m/m/p files, that can be done by simply tweaking the patch level check to reject matching values. For reduced version entries, the filename itself must be compared. v2: Improve comment (review by Daniele) Signed-off-by: John Harrison <John.C.Harrison@Intel.com> Reviewed-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230502234007.1762014-6-John.C.Harrison@Intel.com
2023-05-05drm/i915/uc: Enhancements to firmware table validationJohn Harrison
The validation of the firmware table was being done inside the code for scanning the table for the next available firmware blob. Which is unnecessary. So pull it out into a separate function that is only called once per blob type at init time. Also, drop the CONFIG_SELFTEST requirement and make errors terminal. It was mentioned that potential issues with backports would not be caught by regular pre-merge CI as that only occurs on tip not stable branches. Making the validation unconditional and failing driver load on detecting of a problem ensures that such backports will also be validated correctly. This requires adding a firmware global flag to indicate an issue with any of the per firmware tables. This is done rather than adding a new state enum as a new enum value would be a much more invasive change - lots of places would need updating to support the new error state. Note also that this change means that a table error will cause the driver to wedge even on platforms that don't require firmware files. This is intentional as per the above backport concern - someone doing backports is not guaranteed to test on every platform that they may potential affect. So forcing a failure on all platforms ensures that the problem will be noticed and corrected immediately. v2: Change to unconditionally fail module load on a validation error (review feedback/discussion with Daniele). v3: Add a new flag to track table validation errors (review feedback/discussion with Daniele).
