Thanks to advanced RE of fglrx we finally know what exactly needs to be handled of AFMT change.

DCE3 has ACR and CRC registers swapped which explains why we needed WREG32(HDMI0_AUDIO_CRC_CONTROL + offset, 0x1000); This has been tested for possible regressions on DCE3 HD3470 (RV620).

It's still unsure how we will handle DCE 3.1 vs. DCE 3.2, since they have few differences as well. For now separate DCE 2 and DCE 3 path, so we can work on it without a risk of breaking DCE 3.1+.

2014-06-02drm/radeon: add large PTE support for NI, SI and CIK v5Christian König-9/+98
This patch implements support for VRAM page table entry compression. PTE construction is enhanced to identify physically contiguous page ranges and mark them in the PTE fragment field. L1/L2 TLB support is enabled for 64KB (SI/CIK) and 256KB (NI) PTE fragments, significantly improving TLB utilization for VRAM allocations. Linear store bandwidth is improved from 60GB/s to 125GB/s on Pitcairn. Unigine Heaven 3.0 sees an average improvement from 24.7 to 27.7 FPS on default settings at 1920x1200 resolution with vsync disabled.

The 800x600 (SVGA) screen resolution was lacking in the set of built-in selectable EDID screen resolutions that can be used to repair misbehaving monitor firmware. This patch adds the related data set and expands the documentation. Note that the SVGA bit occupies a different byte to all the existing users of the established timing bits forcing a rework of the ESTABLISHED_TIMINGS_BITS macro.

2014-05-06drm/i915: Merge LP1+ watermarks in safer wayVille Syrjälä-9/+28
On ILK when we disable a particular watermark level, we must maintain the actual watermark values for that level for some time (until the next vblank possibly). Otherwise we risk underruns. In order to achieve that result we must merge the LP1+ watermarks a bit differently since we must also merge levels that are to be disabled. We must also make sure we don't overflow the fields in the watermark registers in case the calculated watermarks come out too big to fit. As early as possbile we mark all computed watermark levels as disabled if they would exceed the register maximums. We make sure to leave the actual watermarks for such levels zeroed out. Then during merging, we take the maxium values for every level, regardless if they're disabled or not. That may seem a bit pointless since at the moment all the watermark levels we merge should have their values zeroed if the level is already disabled. However soon we will be dealing with intermediate watermarks that, in addition to the new watermark values, also contain the previous watermark values, and so levels that are disabled may no longer be zeroed out. v2: Split the patch in two (Paulo) Use if() instead of & when merging ->enable (Paulo) Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Paulo Zanoni <paulo.r.zanoni@intel.com> [danvet: Fix commit message as noted by Paulo.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
