On FBC1 we can specify an arbitrary cfb stride. The hw will simply throw away any compressed line that would exceed the specified limit and keep using the uncompressed data instead. Thus we can allow arbitrary compression limits. The one thing we have to keep in mind though is that the cfb stride is specified in units of 32B (gen2) or 64B (gen3+). Fortunately X-tile is already 128B (gen2) or 512B (gen3+) wide so as long as we limit outselves to the same 4x compression limit that FBC2 has we are guaranteed to have a sufficiently aligned cfb stride.

Apply the same 512 byte FBC segment alignment to glk+ as we use on skl+. The only real difference is that we now have a dedicated register for the FBC override stride. Not 100% sure which platforms really need the 512B alignment, but it's easiest to just do it on everything. Also the hardware no longer seems to misclaculate the CFB stride for linear, so we can omit the use of the override stride for linear unless the stride is misaligned. Reviewed-by:

The code to calculate the cfb stride/size is a bit of mess. The cfb size is getting calculated based purely on the plane stride and plane height. That doesn't account for extra alignment we want for the cfb stride. The gen9 override stride OTOH is just calculated based on the plane width, and it does try to make things more aligned but any extra alignment added there is not considered in the cfb size calculations. So not at all convinced this is working as intended. Additionally the compression limit handling is split between the cfb allocation code and g4x_dpfc_ctl_limit() (for the 16bpp case), which is just confusing. Let's streamline the whole thing: - Start with the plane stride, convert that into cfb stride (cfb is always 4 bytes per pixel). All the calculations will assume 1:1 compression limit since that will give us the max values, and we don't yet know how much stolen memory we will be able to allocate - Align the cfb stride to 512 bytes on modern platforms. This guarantees the 4 line segment will be 512 byte aligned regardles of the final compression limit we choose later. The 512 byte alignment for the segment is required by at least some of the platforms, and just doing it always seems like the easiest option - Figure out if we need to use the override stride or not. For X-tiled it's never needed since the plane stride is already 512 byte aligned, for Y-tiled it will be needed if the plane stride is not a multiple of 512 bytes, and for linear it's apparently always needed because the hardware miscalculates the cfb stride as PLANE_STRIDE*512 instead of the PLANE_STRIDE*64 that it use with linear. - The cfb size will be calculated based on the aligned cfb stride to guarantee we actually reserved enough stolen memory and the FBC hw won't end up scribbling over whatever else is allocated in stolen - The compression limit handling we just do fully in the cfb allocation code to make things less confusing v2: Write the min cfb segment stride calculation in a more explicit way to make it clear what is going on v3: Remeber to update fbc->limit when changing to 16bpp Reviewed-by: Uma Shankar <uma.shankar@intel.com> #v2 Signed-off-by:

PSR always had a requirement to only be enabled if there is active planes but not following that never caused any issues. But that changes in Alderlake-P, leaving PSR enabled without active planes causes transcoder/port underruns. Similar behavior was fixed during the pipe disable sequence by commit 84030adb ("drm/i915/display: Disable audio, DRRS and PSR before planes"). intel_dp_compute_psr_vsc_sdp() had to move from intel_psr_enable_locked() to intel_psr_compute_config() because we need to be able to disable/enable PSR from atomic states without connector and encoder state.

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().

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.

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.

drm_atomic_helper_damage_iter_init() + drm_atomic_for_each_plane_damage() returns the full plane area in case no damaged area was set by userspace or it was discarted by driver. This is important to fix the rendering of userspace applications that does frontbuffer rendering and notify driver about dirty areas but do not set any dirty clips. With this we don't need to worry about to check and mark the whole area as damaged in page flips. Another important change here is the move of drm_atomic_add_affected_planes() call, it needs to called late otherwise the area of all the planes would be added to pipe_clip and not saving power.
