Clean up skl_allocate_pipe_ddb() a bit by moving the 'wm' variable to tighter scope. We'll also consitify it where appropriate. Also initialize plane_alloc/uv_plane_alloc when decrlaring them rather than later. v2: Update commit message (Matt) Cc: Neel Desai <neel.desai@intel.com> Signed-off-by:

Currently we disable all the watermarks above the selected max level for every plane. That would mean that the cursor's watermarks may also get modified when another plane causes the selected max watermark level to change. That is not so great as we would like to keep the cursor as indepenedent as possible to avoid having to throttle it in resposne to other plane activity. To avoid that let's keep the watermarks enabled even for levels above the max selected watermark level, iff the plane has enough ddb for that particular level. This way the cursor's enabled watermarks only depend on the cursor itself. This is safe because the hardware will never choose to use a watermark level unless all enabled planes have also enabled that level. Cc: Neel Desai <neel.desai@intel.com> Signed-off-by:

We use a fixed ddb allocation for the cursor. Now the calculation actually makes sure we have enough ddb space, but let's double check anyway. Cc: Neel Desai <neel.desai@intel.com> Signed-off-by:

Currently we just assume that 32 or 8 blocks of ddb is sufficient for the cursor. The 32 might be, but the 8 is certainly not. The minimum we need is at least what level 0 watermarks need, but that is a bit restrictive, so instead let's calculate what level 7 would need for a 256x256 cursor. We'll use that to determine the fixed ddb allocation for the cursor. This way the cursor will never be responsible for missing out on deeper power saving states. v2: Loop to make sure this works even if some wm levels are totally disabled (latency==0) Cc: Neel Desai <neel.desai@intel.com> Signed-off-by: -

Extract the meat of skl_compute_plane_wm_params() into a lower level helper that doesn't depend on the plane state. We'll reuse this for the cursor ddb allocation calculations. Cc: Neel Desai <neel.desai@intel.com> Signed-off-by:

Ville Syrjälä authored
skl_compute_plane_wm() doesn't actually need the plane state. While it would make logically sense to pass it, we shall need to reuse skl_compute_plane_wm() to compute the minimum ddb allocation for the cursor before the cursor may be enabled. Thus we can't rely on the plane state. The alternative would be to duplicate a lot of the wm calculations for the cursor ddb allocation case, which doens't appeal to me.

We want to allow the desktop PNV to not have .is_mobile set. To that end let's add a small helper to determine if the platform has the ASLE interrupt (or equivalent). Supposdely both PNV variants have it. Cc: Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com> Signed-off-by:

g33/i964g/g45 are the exceptional cases when it comes to the swizzle detection. Let's reorder the code to handle them first and let everything else be handled by the else branch. This allows us to unset .is_mobile for the desktop PNV variant (which supposedly must follow the "mobile" path here). Cc: Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com> Signed-off-by:

Exercise acquiring and releasing forcewake around register reads. In order to read a register behind a GT powerwell, we need to instruct that powerwell to wake up using a forcewake. When we no longer require the GT powerwell, we tell the GT to release our forcewake. Inside the forcewake, the register read should work but outside it should just return garbage, 0 being the most common garbage. Thus we can detect when we are inside and outside of the forcewake with just a simple register read, and so can verify that the GT powerwell is released when we say so. v2: Picking the right forcewaked register to return 0 outside of forcewake is an art.

There is probably a issue in DMC firmwares(icl_dmc_ver1_07.bin and kbl_dmc_ver1_04.bin at least) that causes PSR2 SU to fail after exiting DC6 if EDP_PSR_TP1_TP3_SEL is kept in PSR_CTL, so for now lets workaround the issue by cleaning PSR_CTL before enable PSR2. v2: - Updated commit description and comment to state that it may be a DMC firmware issue (Rodrigo) - No need to RMW, let's write 0 to PSR_CTL(Dhinakaran) Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by:

As the final request on a ring may hold the reference to this ring (via retiring the last pinned context), we may find ourselves chasing a dangling pointer on completion of the list. A quick solution is to hold a reference to the ring itself as we retire along it so that we only free it after we stop dereferencing it. Signed-off-by:
