2017-01-09drm/amd/powerplay: bypass fan table setup if no fan connectedHawking Zhang
commit 10e2ca346bf74561ff1b7fff6287716ab976cd8c upstream. If vBIOS noFan bit is set, the fan table parameters in thermal controller will not get initialized. The driver should avoid to use these uninitialized parameter to do calculation. Otherwise, it may trigger divide 0 error.

commit 0a97c81a9717431e6c57ea845b59c3c345edce67 upstream. Hook up drm_compat_ioctl to support 32-bit userspace on 64-bit kernels. It turns out that N2600 and N2800 comes with 64-bit enabled.

2017-01-09drm/nouveau/fifo/gf100-: protect channel preempt with subdev mutexBen Skeggs
commit b27add13f500469127afdf011dbcc9c649e16e54 upstream. This avoids an issue that occurs when we're attempting to preempt multiple channels simultaneously. HW seems to ignore preempt requests while it's still processing a previous one, which, well, makes sense. Fixes random "fifo: SCHED_ERROR 0d []" + GPCCS page faults during parallel piglit runs on (at least) GM107.

2017-01-09drm/nouveau/ttm: wait for bo fence to signal before unmapping vmasBen Skeggs
commit 10dcab3e7f477bffee88d518aad57d06777cfdf4 upstream. TTM was changed a while back to allow for pipelining of buffer moves, and part of this was the removal of waiting for a BO to idle before calling move(), placing the responsibility on the driver to do this if required. That's all well and good, except, we make use of move_notify() to handle mapping/unmapping from the GPU VMM as move() isn't called on all paths. This commit adds a wait before unmapping from a VMM in move_notify(), to prevent GPU page faults where a buffer is still being accessed.

2017-01-09drm/amd/amdgpu: enable GUI idle INT after enabling CGCGArindam Nath
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.

2016-11-24drm/mediatek: fix a typo of DISP_OD_CFG to OD_RELAYMODEBibby Hsieh
If we want to set the hardware OD to relay mode, we have to set DISP_OD_CFG register rather than OD_RELAYMODE; otherwise, the system will access the wrong address.

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. v2: agd: fix typo Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=98505 Signed-off-by: Peter Wu <peter@lekensteyn.nl> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: <stable@vger.kernel.org> # 4.8+ Reviewed-by: Alex Deucher <alexander.deucher@amd.com>

2016-11-22drm/arm: hdlcd: fix plane base address updateRussell King
While testing HDMI with Xorg on the Juno board, I find that when Xorg starts up or shuts down, the display is shifted significantly to the right and wrapped in the active region. (No sync bars are visible.) The timings are correct, it behaves as if the start address has been shifted many pixels _into_ the framebuffer. This occurs whenever the display mode size is changed - using xrandr in Xorg shows that changing the resolution triggers the problem almost every time, but changing the refresh rate does not. Using devmem2 to disable and re-enable the HDLCD resolves the issue, and repeated disable/enable cycles do not make the issue re-appear. Further debugging shows that we try to update the controller configuration while enabled. Alwys ensure that the HDLCD is disabled prior to updating the controller timings, and use drm_crtc_vblank_off()/drm_crtc_vblank_on() so that DRM knows whether it can expect vblank interrupts.

2016-11-16drm/i915: Assume non-DP++ port if dvo_port is HDMI and there's no AUX ch ↵Ville Syrjälä
specified in the VBT My heuristic for detecting type 1 DVI DP++ adaptors based on the VBT port information apparently didn't survive the reality of buggy VBTs. In this particular case we have a machine with a natice HDMI port, but the VBT tells us it's a DP++ port based on its capabilities. The dvo_port information in VBT does claim that we're dealing with a HDMI port though, but we have other machines which do the same even when they actually have DP++ ports. So that piece of information alone isn't sufficient to tell the two apart. After staring at a bunch of VBTs from various machines, I have to conclude that the only other semi-reliable clue we can use is the presence of the AUX channel in the VBT. On this particular machine AUX channel is specified as zero, whereas on some of the other machines which listed the DP++ port as HDMI have a non-zero AUX channel. I've also seen VBTs which have dvo_port a DP but have a zero AUX channel. I believe those we need to treat as DP ports, so we'll limit the AUX channel check to just the cases where dvo_port is HDMI. If we encounter any more serious failures with this heuristic I think we'll have to have to throw it out entirely. But that could mean that there is a risk of type 1 DVI dongle users getting greeted by a black screen, so I'd rather not go there unless absolutely necessary. v2: Remove the duplicate PORT_A check (Daniel) Fix some typos in the commit message Cc: Daniel Otero <daniel.otero@outlook.com> Cc: stable@vger.kernel.org Tested-by: Daniel Otero <daniel.otero@outlook.com> Fixes: d61992565bd3 ("drm/i915: Determine DP++ type 1 DVI adaptor presence based on VBT") Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97994 Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1478884464-14251-1-git-send-email-ville.syrjala@linux.intel.com Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> (cherry picked from commit 7a17995a3dc8613f778a9e2fd20e870f17789544) Signed-off-by: Jani Nikula <jani.nikula@intel.com>

2016-11-11drm/amdgpu: Attach exclusive fence to prime exported bo's. (v5)Mario Kleiner
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.
