2024-05-31drm/i915: Simplify scanline_offset handling for gen2Ville Syrjälä1-5/+3
Currently intel_crtc_scanline_offset() is careful to always return a positive offset. That is not actually necessary as long as we take care of negative values when applying the offset in __intel_get_crtc_scanline(). This simplifies intel_crtc_scanline_offset(), and makes the scanline_offfset arithmetic more symmetric between the forward (__intel_get_crtc_scanline()) and reverse (intel_crtc_scanline_to_hw()) directions.

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.

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.

2024-05-30drm: atmel-hlcdc: add driver ops to differentiate HLCDC and XLCDC IPManikandan Muralidharan3-83/+172
Add LCD IP specific ops in driver data to differentiate HLCDC and XLCDC code within the atmel-hlcdc driver files. XLCDC in SAM9X7 has different sets of registers and additional configuration bits when compared to previous HLCDC IP. Read/write operation on the controller register and functionality is now separated using the LCD IP specific ops.
