2021-09-23drm/amdgpu: Fix resume failures when device is goneAndrey Grodzovsky1-0/+4
Problem: When device goes into suspend and unplugged during it then all HW programming during resume fails leading to a bad SW during pci remove handling which follows. Because device is first resumed and only later removed we cannot rely on drm_dev_enter/exit here. Fix: Use a flag we use for PCIe error recovery to avoid accessing registres. This allows to successfully complete pm resume sequence and finish pci remove.

2021-09-23drm/i915/adlp: Add support for remapping CCS FBsImre Deak5-47/+89
Add support for remapping CCS FBs on ADL-P to remove the restriction of the power-of-two sized stride and the 2MB surface offset alignment for these FBs. We can only remap the tiles on the main surface, not the tiles on the CCS surface, so userspace has to generate the CCS surface aligning to the POT size padded main surface stride (by programming the AUX pagetable accordingly). For the required AUX pagetable setup, this requires that either the main surface stride is 8 tiles or that the stride is 16 tiles aligned (= 64 kbytes, the area mapped by one AUX PTE). v2: - Init intel_remapped_info::plane_alignment only for remapped views and do this from intel_fb_view_init().

2021-09-23drm/i915/uncore: fwtable read handlers are now used on all forcewake platformsMatt Roper1-9/+2
With the recent refactor of the uncore mmio handling, all forcewake-based platforms (i.e., graphics version 6 and beyond) now use the 'fwtable' read handlers. Let's pull the assignment out of the per-platform if/else ladder to make this more obvious.

2021-09-23drm/i915/adlp: Require always a power-of-two sized CCS surface strideImre Deak1-4/+30
At the moment CCS FB strides must be power-of-two sized, but a follow-up change will add support remapping these FBs, allowing the FB passed in by userspace to have a non-POT sized stride. For these remapped FBs we can only remap the main surface, not the CCS surface. This means that userspace has to always generate the CCS surface aligning to the POT stride padded main surface (by setting up the CCS AUX pagetables accordingly). Adjust the CCS surface stride check to enforce this. No functional change. v2: - Fix the gen12_ccs_aux_stride() is not static sparse warning.

2021-09-23drm/i915: Use tile block based dimensions for CCS origin x, y checkImre Deak1-5/+25
The tile size for all surface types is 4 kbyte (or 2 kbyte on old platforms), with the exception of the TGL/ADL CCS surface where the tile size is 64 bytes. To be able to remap CCS FBs the CCS surface tile needs to be defined as 4 kbyte as well (the granularity of GTT pages in a remapped view). The only place using the dimension of the 64 byte CCS area is the initial check for the main vs. CCS plane origin coordinate match. To prepare for adding support for remapping CCS FBs let's call the 64 byte CCS area a 'tile block' and add a helper to retrieve the dimensions for it. No functional change.
