2014-02-05drm/i915: Reorganize display pipe register accessesAntti Koskipaa
RFCv2: Reorganize array indexing so that full offsets can be used as is. It makes grepping for registers in i915_reg.h much easier. Also move offset arrays to intel_device_info. v1: Fixed offsets for VLV, proper eDP handling v2: Fixed BCLRPAT, PIPESRC, PIPECONF and DSP* macros. v3: Added EDP pipe comment, removed redundant offset arrays for MSA_MISC and DDI_FUNC_CTL. v4: Rename patch and report object size increase. v5: Change location of commas, add PIPE_EDP into enum pipe v6: Insert PIPE_EDP_OFFSET into pipe offset array v7: Set I915_MAX_PIPES back to 3, change more registers accessors to use the new macros, get rid of _PIPE_INC and add dev_priv as a parameter where required by the new macros. Upcoming hardware will not have the various display pipe register ranges evenly spaced in memory. Change register address calculations into array lookups. Tested on SNB, VLV, IVB, Gen2 and HSW w/eDP. I left the UMS cruft untouched.

2014-01-30drm/i915: vlv: fix DP PHY lockup due to invalid PP sequencer setupImre Deak
Atm we setup the HW panel power sequencer logic both for eDP and DP ports. On eDP we then go on and start the power on sequence and commence with link training when it's ready. On DP we don't do the power on sequencing but do the link training immediately. At this point the DP PHY block gets stuck, since - supposedly - it is waiting for the power on sequence to finish. The actual register write that seems to hold off the PHY is PIPEX_PP_ON_DELAYS[Panel Control Port Select]. Writing here a non-0 value eventually sets PIPEX_PP_STATUS[Require Asset Status] to 1 and blocks the PHY until the panel power on is ready. Fix this by not doing any PP sequencing setup for DP ports. Thanks to Ville Syrjälä, Jesse Barnes and Todd Previte for the help in tracking this down. Note that on older gmch platforms (where we have lvds instead of edp) we've hacked around this by writing the magic ABCD unlock key to PP registers, which disables the hw sanity checks. For edp all platforms thus far had the pch split, with the edp port in the north display complex and the PP registers on the pch the hw sanity checks (expressed through the "Require Asset Status" bit) was never functional, hence never a real issue.

2014-01-30drm/i915: Don't access snooped pages through the GTT (even for error capture)Chris Wilson
We want to use the GTT for reading back objects upon an error so that we have exactly the information that the GPU saw. However, it is verboten to access snoopable pages through the GTT and causes my PineView GPU to throw a page fault instead. This has not been a problem in the past as we only dumped ringbuffers and batchbuffers, both of which must be not snooped. However, the introduction of HWS page dumping leads to a read of a snooped object through the GTT.

2014-01-29drm/i915: VM eviction only targets address space not physical pagesChris Wilson
During eviction, we are only considering how to free up space within the current address space and not concerned with freeing up physical memory. As such we need only skip nodes that pinned in the current VM and not globally.

2014-01-29drm/radeon: fix DAC interrupt handling on DCE5+Alex Deucher
DCE5 and newer hardware only has 1 DAC. Use the correct offset. This may fix display problems on certain board configurations. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org
2014-01-29drm/radeon: clean up active vram sizingAlex Deucher
If we are not able to properly initialize one of the gpu engines for buffer paging, we limit vram to the size of the cpu visible aperture. We generally either use the gfx or dma engine to do this. Clean up the size limiting code to only adjust the size based on what ring is selected for buffer paging rather than making assumptions about which engine is selected for paging.

2014-01-29drm/radeon: skip async dma init on r6xxAlex Deucher
The hw is buggy and it's not currently used, but it's currently still initialized by the driver. Skip the init. Skipping init also seems to improve stability with dpm on some r6xx asics. bug: https://bugs.freedesktop.org/show_bug.cgi?id=66963 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com>

Prevent runtime suspend of non-PX GPUs. Runtime suspend is not what we want in those cases. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org
