Like for the global gtt we want a notch more flexibility here. Only big change (besides a few tiny function parameter adjustments) was to move gen6_ppgtt_insert_entries up (and remove _sg_ from its name, we only have one kind of insert_entries since the last gtt cleanup). We could also extract the platform ppgtt setup/teardown code a bit better, but I don't care that much. With this we have the hw details of pte writing nicely hidden away behind a bit of abstraction. Which should pave the way for different/multiple ppgtts (e.g. what we need for real ppgtt support). Reviewed-by:

We have a few too many differences here, so finally take the prepared abstraction and run with it. A few smaller changes are required to get things into shape: - move i915_cache_level up since we need it in the gt funcs - split up i915_ggtt_clear_range and move the two functions down to where the relevant insert_entries functions are - adjustments to a few function parameter lists Now we have 2 functions which deal with the gen6+ global gtt (gen6_ggtt_ prefix) and 2 functions which deal with the legacy gtt code in the intel-gtt.c fake agp driver (i915_ggtt_ prefix). Init is still a bit a mess, but honestly I don't care about that. One thing I've thought about while deciding on the exact interfaces is a flag parameter for ->clear_range: We could use that to decide between writing invalid pte entries or scratch pte entries. In case we ever get around to fixing all our bugs which currently prevent us from filling the gtt with empty ptes for the truly unused ranges ... Signed-off-by:

/sys/kernel/debug has more or less been the standard location of debugfs for several years now. Other parts of DRM already use this location, so we should as well. Signed-off-by:

Note that this slightly changes the order, but we only move it within the block of registers that restore encoder state. Specifically LVDS is now restored after DP, whereas previously it was done before. Legacy vga is still restored afterwards, which seems to be the important thing (if there's anything important in this restore ordering at all). Reviewed-by:

The only thing we really care about that it is off. To do so, reuse the recently created i915_redisable_vga function, which is already used to put obnoxious firmware into check on lid reopening. Reviewed-by:

Similarly to how i915_dma.c is shaping up to be the dungeon hole for all things supporting dri1, create a new one to hide all the crazy things which are only really useful for ums support. Biggest part is the register suspend/resume support. Unfortunately a lot of it is still intermingled with bits and pieces we might still need, so needs more analysis and needs to stay in i915_suspend.c for now. Reviewed-by:

That way the control flow is clearer, and it prepares the stage to extract these ums functions and hide them somewhere. There's still tons of display stuff outside of these, but that requires more work. Reviewed-by:

Our suspend code touches a lot of registers all over the place, so we need to enable the power well before suspending. Signed-off-by:

Instead of setting it at the beginning of haswell_crtc_mode_set, let's set it at the beginning of intel_crtc_mode_set. When intel_crt_mode_set calls drm_vblank_pre_modeset we already need to have the transcoder_edp correctly set, because eventually drm_vblank_pre_modeset calls functions that call i915_pipe_enabled from i915_irq.c, which will read PIPECONF(cpu_transcoder). This is a bug that affects us since we added support for TRANSCODER_EDP, but I was only able to see the problem after suspending a machine with the power well disabled (got an "unclaimed register" error.

We should avoid touching registers that are on the power down well when we don't need to, because if we touch these registers when the power well is disabled we'll get tons of "unclaimed register" messages. This commit fixes some of these messages. Signed-off-by:

The current code was wrong in many different ways, so this is a full rewrite. We don't have "different power wells for different parts of the GPU", we have a single power well, but we have multiple registers that can be used to request enabling/disabling the power well. So let's be a good citizen and only use the register we're suppose to use, except when we're loading the driver, where we clear the request made by the BIOS. If any of the registers is requesting the power well to be enabled, it will be enabled. If none of the registers is requesting the power well to be enabled, it will be disabled. For now we're just forcing the power well to be enabled, but in the next commits we'll change this. V2: - Remove debug messages that could be misleading due to possible race conditions with KVMr, Debug and BIOS. - Don't wait on disabling: after a conversaion with a hardware engineer we discovered that the "restriction" on bit 31 is just for the "enable" case, and we don't even need to wait on the "disable" case.
