The timeline->name is only used for convenience in pretty printing the i915_request.fence->ops->get_timeline_name() and it is just as convenient to pull it from the gem_context directly. The few instances of its use inside GEM_TRACE() has proven more of a nuisance than helpful, so not worth saving imo. Signed-off-by:

The user_handle need only be known by userspace for it to lookup the context via the idr; internally we have no use for it. Signed-off-by:

Chris Wilson authored
Define a mutex for the exclusive use of interacting with the per-file context-idr, that was previously guarded by struct_mutex. This allows us to reduce the coverage of struct_mutex, with a view to removing the last bits coordinating GEM context later. (In the short term, we avoid taking struct_mutex while using the extended constructor functions, preventing some nasty recursion.) v2: s/context_lock/context_idr_lock/ Signed-off-by:

Chris Wilson authored
In later patches, it became apparent that userspace can see a partially constructed GEM context and begin using it before it was ready, to much hilarity. Close this window of opportunity by lifting the registration of the context with userspace (the insertion of the context into the filp's idr) to the very end of the CONTEXT_CREATE ioctl.

gcc-4.8 and older dislike the use of __builtin_constant_p() within a constant expression context, and so we must use the magical __is_constexpr() instead. For example, with gcc-4.8.5: ../drivers/gpu/drm/i915/i915_reg.h:167:27: error: first argument to ‘__builtin_choose_expr’ not a constant ../include/linux/build_bug.h:16:45: error: bit-field ‘<anonymous>’ width not an integer constant Reported-by:

Ville Syrjälä authored
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:
-
Ville Syrjälä authored
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.

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.
