2014-06-02drm/radeon: Limit hdmi deep color bit depth to 12 bpc.Mario Kleiner
DCE-4/5/6 can't support more than 12 bpc deep color over hdmi, so clamp to 12 bpc when a hdmi deep color capable display is connected. This even makes sense on DCE-8+, which could do up to 16 bpc, as driving with more than 12 bpc would only waste video bandwidth as long as we don't support framebuffers with more than 12 bpc depth. On pre-DCE4 we clamp hdmi bit depth to 8 bpc, as those asics don't support hdmi deep color.

2014-06-02drm/radeon: Setup HDMI_CONTROL for hdmi deep color gcp's (v2)Alex Deucher

2014-06-02drm/radeon: fix pll setup for hdmi deep color (v7)Alex Deucher
Need to adjust the pll up for deep color modes. Additionally, the atom bpc defines were wrong in certain cases. v2: set the adjusted clock to the pll clock for hdmi deep color. This fixes display and audio issues with deep color as reported by Andy Furniss <adf.lists@gmail.com> v3: set crtc_clock as well v4: setcrtcinfo on the adjusted mode v5: just use the adjusted clock for setting the pll v6: only use the adjusted clock for hdmi v7: only DCE5 and DCE6 and bpc > 8 Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

What initially seemed to be a typo in fglrx (using register 0x740c instead of 0x74dc) appeared to be a correct behavior. 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
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.
