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. See main comment in radeon_vm.c for a technical description. v2 (chk): rebased and simplified. v3 (chk): add missing hw setup v4 (chk): rebased on current drm-fixes-3.15 v5 (chk): fix comments and commit text Signed-off-by: Jay Cornwall <jay@jcornwall.me> Signed-off-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2014-05-01drm/radeon: use pflip irq on R600+ v2Christian König
Testing the update pending bit directly after issuing an update is nonsense cause depending on the pixel clock the CRTC needs a bit of time to execute the flip even when we are in the VBLANK period. This is just a non invasive patch to solve the problem at hand, a more complete and cleaner solution should follow in the next merge window.

2014-03-03drm/radeon: validate relocations in the order determined by userspace v3Marek Olšák
Userspace should set the first 4 bits of drm_radeon_cs_reloc::flags to a number from 0 to 15. The higher the number, the higher the priority, which means a buffer with a higher number will be validated sooner. The old behavior is preserved: Buffers used for write are prioritized over read-only buffers if the userspace doesn't set the number. v2: add buffers to buckets directly, then concatenate them v3: use a stable sort Signed-off-by: Marek Olšák <marek.olsak@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com>
2014-03-03drm/radeon: track memory statistics about VRAM and GTT usage and buffer moves v2Marek Olšák
The statistics are: - VRAM usage in bytes - GTT usage in bytes - number of bytes moved by TTM The last one is actually a counter, so you need to sample it before and after command submission and take the difference. This is useful for finding performance bottlenecks. Userspace queries are also added. v2: use atomic64_t Signed-off-by: Marek Olšák <marek.olsak@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com>
2014-03-03drm/radeon: add a way to get and set initial buffer domains v2Marek Olšák
