Various parts of the cdclk code need access the full atomic state. Currently it's being dug out via the cdclk_state->base.state pointer, which is not great as that pointer isn't always valid.

2024-05-31drm/i915/display: add support for subplatformsJani Nikula2-0/+230
Add support for subplatforms. This is similar to what the xe driver is doing. The subplatform is an enum and it's exclusive, i.e. only one subplatform can match, and it completely identifies the platform and subplatform. This is different from i915 core, and is notable in the handling of ULT/ULX and RPL/RPL-U.

2024-05-31drm/i915/display: add platform descriptorsJani Nikula1-232/+326
We'll need to start identifying the platforms independently in display code in order to break free from the i915 and xe IS_<PLATFORM>() macros. This is fairly straightforward, as we already identify most platforms by PCI ID in display probe anyway. As the first step, add platform descriptors with pointers to display info. We'll have more platforms than display info, so minimize duplication: - Add separate skl/kbl/cfl/cml descriptors while they share the display info. - Add separate jsl/ehl descriptors while they share the display info. Identify ADL-P (and derivatives) and DG2 descriptors by their names even though their display info is Xe LPD or HPD.

2024-05-31drm/xe: Split MCR initializationMichal Wajdeczko3-7/+27
The initialization order of GT topology, MCR, PAT and GuC HWconfig as done today by native/PF driver, can't be followed as-is by the VF driver, since fuse registers used in GT topology discovery will be obtained by the VF driver from the GuC in HWconfig step. While native/PF drivers need to program the HW PAT table prior to loading the GuC, this requires only multicast writes support from the MCR code, which could be initialized separately from the full MCR support that requires the GT topology to setup steering data. Split MCR initialization into two steps to avoid introducing VF specific code paths. This also fixes duplicated spin_lock inits.

2024-05-30Revert "drm/xe: make gt_remove use devm"Daniele Ceraolo Spurio3-9/+30
This reverts commit cd506a33b0d9759e0a58556799b1b38650fa3698. The gt_remove function was explicitly added as part of the remove flow instead of using drmm/devm automatic cleanup due to it being illegal to remove a component after the driver has been detached from the pci device; the GSC proxy component is removed as part of gt_remove, so we need to do it in the pci cleanup flow. The function already has a comment above it to explain this. Note that the change to use the devm also caused an invalid pointer deref in the gsc_proxy unbind function, but I didn't bother to debug which pointer was bad since we shouldn't be calling the unbind that late anyway and this revert fixes it. Both issue were not seen in CI because the GSC loading is temporarily disabled due to a critical bug, which means we're not binding the component.

Flickering was observed when using partial mode. Moving the vsync to the same position as used by the default sitronix-st7789v timing resolves this issue.

2024-05-30drm/i915: move uapi.event outside spinlock in intel_crtc_vblank_workLuca Coelho1-1/+1
In intel_crtc_vblank_work(), we access uapi.event before grabbing the event_lock spinlock, but modify it inside the spinlock block. This causes some static analyzers to get confused and issue a warning. The uapi.event value is not protected by the event_lock, so we can safely move it out of the protected block to prevent false positives.

2024-05-30drm/i915/bios: double check array-boundary in parse_sdvo_lvds_dataLuca Coelho1-0/+12
During static analysis, a concern was raised that we may access the dtd->dtd[] array out of bounds, because we are not checking whether the index we use is larger than the array. This should not be a problem as is, because the enumeration that is used for this index comes from "panel_type", which uses an enumeration with 4 items. But if this enumeration is ever changed, it can lead to hard-to-detect bugs, so better double-check it before using it as an index to the array.

2024-05-30drm/i915/display: Add compare config for MTL+ platformsMika Kahola4-10/+109
Currently, we may bump into pll mismatch errors during the state verification stage. This happens when we try to use fastset instead of full modeset. Hence, we would need to add a check for pipe configuration to ensure that the sw and the hw configuration will match. In case of hw and sw mismatch, we would need to disable fastset and use full modeset instead. v2: Fix C10 error on PLL comparison (BAT) Use memcmp instead of fixed loops for pll config comparison (Jani) Clean up and use intel_cx0pll_dump_hw_state() to dump pll information (Jani) Reviewed-by: Jani Nikula <[email protected]> Signed-off-by: Mika Kahola <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

Decouple xe_lrc from xe_exec_queue and reference count xe_lrc.

2024-05-29drm/xe: Remove unwanted mutex lockingNiranjana Vishwanathapura1-2/+6
Do not hold xef->exec_queue.lock mutex while parsing the xarray xef->exec_queue.xa in xe_file_close() as it is not needed and will cause an unwanted dependency between this lock and the vm->lock. This lock protects the exec queue lookup and reference taking which doesn't apply to this code path. When FD is closing, IOCTLs presumably can't be modifying the xarray. v2: Update commit text (Matt Brost) v3: Add more code comment (Rodrigo Vivi) v4: Further expand code comment (Rodirgo Vivi) Signed-off-by: Niranjana Vishwanathapura <[email protected]> Reviewed-by: Matthew Brost <[email protected]> Reviewed-by: Jagmeet Randhawa <[email protected]> Acked-by: Rodrigo Vivi <[email protected]> Signed-off-by: Matthew Brost <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

Support for I2C_CLASS_SPD is currently being removed from the kernel. Only remaining step is to remove the definition of I2C_CLASS_SPD. Setting I2C_CLASS_SPD in a driver is a no-op meanwhile, so remove it here.
