* drm/amdgpu: Add missing lb_vblank_lead_lines setup to DCE-6 path.Mario Kleiner2017-05-25
| | | | | | | | | | | | | commit effaf848b957fbf72a3b6a1ad87f5e031eda0b75 upstream. This apparently got lost when implementing the new DCE-6 support and would cause failures in pageflip scheduling and timestamping.

* drm/amdgpu: Avoid overflows/divide-by-zero in latency_watermark calculations.Mario Kleiner2017-05-25
| | | | | | | | | | | | | | | | | | | | | | | commit e190ed1ea7458e446230de4113cc5d53b8dc4ec8 upstream. At dot clocks > approx. 250 Mhz, some of these calcs will overflow and cause miscalculation of latency watermarks, and for some overflows also divide-by-zero driver crash ("divide error: 0000 [#1] PREEMPT SMP" in "dce_v10_0_latency_watermark+0x12d/0x190"). This zero-divide happened, e.g., on AMD Tonga Pro under DCE-10, on a Displayport panel when trying to set a video mode of 2560x1440 at 165 Hz vrefresh with a dot clock of 635.540 Mhz. Refine calculations to avoid the overflows. Tested for DCE-10 with R9 380 Tonga + ASUS ROG PG279 panel.

* drm/amdgpu: Make display watermark calculations more accurateMario Kleiner2017-05-25
| | | | | | | | | | | | | | | | | commit d63c277dc672e0c568481af043359420fa9d4736 upstream. Avoid big roundoff errors in scanline/hactive durations for high pixel clocks, especially for >= 500 Mhz, and thereby program more accurate display fifo watermarks. Implemented here for DCE 6,8,10,11. Successfully tested on DCE 10 with AMD R9 380 Tonga.

* drm/amd/amdgpu: enable GUI idle INT after enabling CGCGArindam Nath2017-01-09
| | | | | | | | | | | | | | | | | | | | | | commit dd31ae9ac933636c3712b7dd0f6152c1d71f81fe upstream. GUI idle interrupts should be enabled only after we have enabled coarse grain clock gating (CGCG). This prevents GFX engine generating idle interrupt even though CGCG is not completely enabled. Most of the time this goes un-noticed, but on some Stoney ASICs this results in GFX engine hang after system resumes from suspend. The issue is not particular to Stoney though and could have occured on any ASIC. The patch fixes this issue.

| | | | | | | | | | | | | | The ATPX method does not always exist on the dGPU, it may be located at the iGPU. The parent device of the iGPU is the root port for which bridge_d3 is false.

* drm/amdgpu: fix power state when port pm is unavailablePeter Wu2016-11-23
| | | | | | | | | | | | | | | | | | | | When PCIe port PM is not enabled (system BIOS is pre-2015 or the pcie_port_pm=off parameter is set), legacy ATPX PM should still be marked as supported. Otherwise the GPU can fail to power on after runtime suspend. This affected a Dell Inspiron 5548. Ideally the BIOS date in the PCI core is lowered to 2013 (the first year where hybrid graphics platforms using power resources was introduced), but that seems more risky at this point and would not solve the pcie_port_pm=off issue.

* drm/amdgpu: Attach exclusive fence to prime exported bo's. (v5)Mario Kleiner2016-11-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | External clients which import our bo's wait only for exclusive dmabuf-fences, not on shared ones, ditto for bo's which we import from external providers and write to. Therefore attach exclusive fences on prime shared buffers if our exported buffer gets imported by an external client, or if we import a buffer from an external exporter. See discussion in thread: https://lists.freedesktop.org/archives/dri-devel/2016-October/122370.html Prime export tested on Intel iGPU + AMD Tonga dGPU as DRI3/Present Prime render offload, and with the Tonga standalone as primary gpu. v2: Add a wait for all shared fences before prime export, as suggested by Christian Koenig. v3: - Mark buffer prime_exported in amdgpu_gem_prime_pin, so we only use the exclusive fence when exporting a bo to external clients like a separate iGPU, but not when exporting/importing from/to ourselves as part of regular DRI3 fd passing. - Propagate failure of reservation_object_wait_rcu back to caller. v4: - Switch to a prime_shared_count counter instead of a flag, which gets in/decremented on prime_pin/unpin, so we can switch back to shared fences if all clients detach from our exported bo. - Also switch to exclusive fence for prime imported bo's. v5: - Drop lret, instead use int ret -> long ret, as proposed by Christian.

The purpose of this change is to make the use of FOLL_FORCE explicit so it is easier to grep for and clearer to callers that this flag is being used. The use of FOLL_FORCE is an issue as it overrides missing VM_READ/VM_WRITE flags for the VMA whose pages we are reading from/writing to, which can result in surprising behaviour. The patch series came out of the discussion around commit 38e088546522 ("mm: check VMA flags to avoid invalid PROT_NONE NUMA balancing"), which addressed a BUG_ON() being triggered when a page was faulted in with PROT_NONE set but having been overridden by FOLL_FORCE. do_numa_page() was run on the assumption the page _must_ be one marked for NUMA node migration as an actual PROT_NONE page would have been dealt with prior to this code path, however FOLL_FORCE introduced a situation where this assumption did not hold. See https://marc.info/?l=linux-mm&m=147585445805166 for the patch proposal" Additionally, there's a fix for an ancient bug related to FOLL_FORCE and FOLL_WRITE by me. [ This branch was rebased recently to add a few more acked-by's and reviewed-by's ] * gup_flag-cleanups: mm: replace access_process_vm() write parameter with gup_flags mm: replace access_remote_vm() write parameter with gup_flags mm: replace __access_remote_vm() write parameter with gup_flags mm: replace get_user_pages_remote() write/force parameters with gup_flags mm: replace get_user_pages() write/force parameters with gup_flags mm: replace get_vaddr_frames() write/force parameters with gup_flags mm: replace get_user_pages_locked() write/force parameters with gup_flags mm: replace get_user_pages_unlocked() write/force parameters with gup_flags mm: remove write/force parameters from __get_user_pages_unlocked() mm: remove write/force parameters from __get_user_pages_locked() mm: remove gup_flags FOLL_WRITE games from __get_user_pages()
| * mm: replace get_user_pages() write/force parameters with gup_flagsLorenzo Stoakes2016-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes the 'write' and 'force' from get_user_pages() and replaces them with 'gup_flags' to make the use of FOLL_FORCE explicit in callers as use of this flag can result in surprising behaviour (and hence bugs) within the mm subsystem.

Properly check the the type rather than using the type id as an index. v2: fix all the IPs to not use IP type as an idx as well.
