2014-06-02drm/radeon: add large PTE support for NI, SI and CIK v5Christian König1-1/+4
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.

2014-05-01drm/radeon: use pflip irq on R600+ v2Christian König1-7/+21
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.

2014-01-30drm/radeon: clean up active vram sizingAlex Deucher1-1/+5
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.

2013-12-25drm/radeon: remove generic rptr/wptr functions (v2)Alex Deucher1-8/+0
Fill in asic family specific versions rather than using the generic version. This lets us handle asic specific differences more easily. In this case, we disable sw swapping of the rtpr writeback value on r6xx+ since the hw does it for us.

2013-12-25drm/radeon/pm: move pm handling into the asic specific codeAlex Deucher1-5/+14
We need more control over the ordering of dpm init with respect to the rest of the asic. Specifically, the SMC has to be initialized before the rlc and cg/pg. The pm code currently initializes late in the driver, but we need it to happen much earlier so move pm handling into the asic specific callbacks. This makes dpm more reliable and makes clockgating work properly on CIK parts and should help on SI parts as well. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

Unigine Sanctuary on Bonaire: Before: 15 fps After: 90 fps Judging from the fan noise, the GPU was also underclocked when the other render backends were disabled, resulting in horrible performance.

git://people.freedesktop.org/~danvet/drm-intel into drm-next Bit a bit -fixes pull request in the merge window than usual dua to two feauture-y things: - Display CRCs are now enabled on all platforms, including the odd DP case on gm45/vlv. Since this is a testing-only feature it should ever hurt, but I figured it'll help with regression-testing -fixes. So I left it in and didn't postpone it to 3.14. - Display power well refactoring from Imre. Would have caused major pain conflict with the bdw stage 1 patches if I'd postpone this to -next. It's only an relatively small interface rework, so shouldn't cause pain. It's also been in my tree since almost 3 weeks already. That accounts for about two thirds of the pull, otherwise just bugfixes: - vlv backlight fix from Jesse/Jani - vlv vblank timestamp fix from Jesse - improved edp detection through vbt from Ville (fixes a vlv issue) - eDP vdd fix from Paulo - fixes for dvo lvds on i830M - a few smaller things all over Note: This contains a backmerge of v3.12. Since the -internal branch always applied on top of -nightly I need that unified base to merge bdw patches. So you'll get a conflict with radeon connector props when pulling this (and nouveau/master will also conflict a bit when Ben doesn't rebase). The backmerge itself only had conflicts in drm/i915.

The vram scratch buffer needs to be initialized before the mc is programmed otherwise we program 0 as the GPU address of the default GPU fault page. In most cases we put vram at zero anyway and reserve a page for the legacy vga buffer so in practice this shouldn't cause any problems, but better to make it correct.

Also add a new RADEON_INFO query to check that CP DMA packets are supported on the compute ring. CP DMA has been supported since the 3.8 kernel, but due to an oversight we forgot to teach the CS checker that the CP DMA packet was legal for the compute ring on Southern Islands GPUs. This patch fixes a bug where the radeon driver will incorrectly reject a legal CP DMA packet from user space.

2013-08-31drm/radeon: fixes for gfx clockgating on SIAlex Deucher1-13/+4
Clockgating requires signalling between the CP and the RLC to work properly. Resetting the CP block in the CP resume code messed up the internal coordination between the blocks. Removing the reset allows gfx clockgating to work properly.
