The SF and clipper units mishandle the provoking vertex in some cases, which can cause misrendering with shaders that use flat shaded inputs. There are chicken bits in 3D_CHICKEN3 (for SF) and FF_SLICE_CHICKEN (for the clipper) that work around the issue. These registers are unfortunately not part of the logical context (even the power context), and so we must reload them every time we start executing in a context.

2018-06-19drm/i915: Fix context ban and hang accounting for clientMika Kuoppala3-25/+55
If client is smart or lucky enough to create a new context after each hang, our context banning mechanism will never catch up, and as a result of that it will be saved from client banning. This can result in a never ending streak of gpu hangs caused by bad or malicious client, preventing access from other legit gpu clients. Fix this by always incrementing per client ban score if it hangs in short successions regardless of context ban scoring. The exception are non bannable contexts. They remain detached from client ban scoring mechanism. v2: xchg timestamp, tidyup (Chris) v3: comment, bannable & banned together (Chris) Fixes: b083a0870c79 ("drm/i915: Add per client max context ban limit") Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20180615104429.31477-1-mika.kuoppala@linux.intel.com (cherry picked from commit 14921f3cef85b0167a9145e5f29b9dfc3b2a84dc) Signed-off-by: Jani Nikula <jani.nikula@intel.com>
2018-06-19drm/i915: Turn off g4x DP port in .post_disable()Ville Syrjälä1-16/+8
While Bspec doesn't list a specific sequence for turning off the DP port on g4x we are getting an underrun if the port is disabled in the .disable() hook. Looks like the pipe stops when the port stops, and by that time the plane disable may not have completed yet. Also the plane(s) seem to end up in some wonky state when this happens as they also signal another underrun immediately after we turn them back on during the next enable sequence. We could add a vblank wait in .disable() to avoid wedging the planes, but I assume we're still tripping up the pipe in some way. So it seems better to me to just follow the ILK+ sequence and turn off the DP port in .post_disable() instead. This sequence doesn't seem to suffer from this problem. Could be it was always the intended sequence for DP and the gen4 bspec was just never updated to include it. Originally we used the bad sequence even on ilk+, but I changed that in commit 08aff3fe26ae ("drm/i915: Move DP port disable to post_disable for pch platforms") as it was causing issues on those platforms as well. I left out g4x then only because I didn't have the hardware to test it. Now that I do it's fairly clear that the ilk+ sequence is also the right choice for g4x. v2: Fix whitespace fail (Jani) Mention the ilk+ commit (Jani) Cc: stable@vger.kernel.org Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180613160553.11664-2-ville.syrjala@linux.intel.com Reviewed-by: Jani Nikula <jani.nikula@intel.com> (cherry picked from commit 51a9f6dfc00d35f927ecfaf6f0ae8ebaba39b3fe) Signed-off-by: Jani Nikula <jani.nikula@intel.com>

2018-06-19drm/i915: Fix PIPESTAT irq ack on i965/g4xVille Syrjälä1-2/+10
On i965/g4x IIR is edge triggered. So in order for IIR to notice that there is still a pending interrupt we have to force and edge in ISR. For the ISR/IIR pipe event bits we can do that by temporarily clearing all the PIPESTAT enable bits when we ack the status bits. This will force the ISR pipe event bit low, and it can then go back high when we restore the PIPESTAT enable bits. This avoids the following race: 1. stat = read(PIPESTAT) 2. an enabled PIPESTAT status bit goes high 3. write(PIPESTAT, enable|stat); 4. write(IIR, PIPE_EVENT) The end result is IIR==0 and ISR!=0. This can lead to nasty vblank wait/flip_done timeouts if another interrupt source doesn't trick us into looking at the PIPESTAT status bits despite the IIR PIPE_EVENT bit being low. Before i965 IIR was level triggered so this problem can't actually happen there. And curiously VLV/CHV went back to the level triggered scheme as well. But for simplicity we'll use the same i965/g4x compatible code for all platforms.

2018-06-19drm/i915: Allow DBLSCAN user modes with eDP/LVDS/DSIVille Syrjälä10-5/+84
When encountering a connector with the scaling mode property both intel and modesetting ddxs sometimes add tons of DBLSCAN modes to the output's mode list. The idea presumably being that since the output will be going through the panel fitter anyway we can pretend to use any kind of mode. Sadly that means we can't reject user modes with the DBLSCAN flag until we know whether we're going to be using the panel's native mode or the user mode directly. Doing otherwise means X clients using xf86vidmode/xrandr will get a protocol error (and often self terminate as a result) when the kernel refuses to use the requested mode with the DBLSCAN flag. To undo the regression we'll move the DBLSCAN checks into the connector->mode_valid() and encoder->compute_config() hooks.

2018-06-19drm/i915: Apply batch location restrictions before pinningChris Wilson1-22/+27
We special case the position of the batch within the GTT to prevent negative self-relocation deltas from underflowing. However, that restriction is being applied after a trial pin of the batch in its current position. Thus we are not rejecting an invalid location if the batch has been used before, leading to an assertion if we happen to need to rearrange the entire payload. In the worst case, this may cause a GPU hang on gen7 or perhaps missing state.

This reverts commit 2c17a4368aad2b88b68e4390c819e226cf320f70. The offending commit triggers a run-time fault when accessing the panel element of the sun4i_tcon structure when no such panel is attached. It was apparently assumed in said commit that a panel is always used with the TCON. Although it is often the case, this is not always true. For instance a bridge might be used instead of a panel.

As hw required, soc clock must large than mclk, So we set max soc clock to OD Max Memory clk. But on workstation, vbios do not support OD feature, the OD max memory clock is equal to 0. In this case, driver can support underclocking. and set od max memory clock to the value in highest memory dpm level. So the od max memory clock should be less than highest soc clock. and driver should not change the soc clock. caused by commit ca57b9b0a156 ("drm/amd/pp: Allow underclocking when od table is empty in vbios") Reviewed-by: Evan Quan <evan.quan@amd.com> Signed-off-by: Rex Zhu <Rex.Zhu@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2018-06-13drm/amd/display: Fix stale buffer object (bo) usePratik Vishwakarma1-11/+0
Fixes stale buffer object (bo) usage for cursor plane Cursor plane's bo operations are handled in DC code. Currently, atomic_commit() does not handle bo operations for cursor plane, as a result the bo assigned for cursor plane in dm_plane_helper_prepare_fb() is not coherent with the updates to the same made in dc code.This mismatch leads to "bo" corruption and hence crashes during S3 entry.

2018-06-13drm/amdgpu: Grab/put runtime PM references in atomic_commit_tail()Lyude Paul1-0/+13
So, unfortunately I recently made the discovery that in the upstream kernel, the only reason that amdgpu is not currently suffering from issues with runtime PM putting the GPU into suspend while it's driving displays is due to the fact that on most prime systems, we have sound devices associated with the GPU that hold their own runtime PM ref for the GPU. What this means however, is that in the event that there isn't any kind of sound device active (which can easily be reproduced by building a kernel with sound drivers disabled), the GPU will fall asleep even when there's displays active. This appears to be in part due to the fact that amdgpu has not actually ever relied on it's rpm_idle() function to be the only thing keeping it running, and normally grabs it's own power references whenever there are displays active (as can be seen with the original pre-DC codepath in amdgpu_display_crtc_set_config() in amdgpu_display.c). This means it's very likely that this bug was introduced during the switch over the DC. So to fix this, we start grabbing runtime PM references every time we enable a previously disabled CRTC in atomic_commit_tail(). This appears to be the correct solution, as it matches up with what i915 does in i915/intel_runtime_pm.c. The one sideaffect of this is that we ignore the variable that the pre-DC code used to use for tracking when it needed runtime PM refs, adev->have_disp_power_ref. This is mainly because there's no way for a driver to tell whether or not all of it's CRTCs are enabled or disabled when we've begun committing an atomic state, as there may be CRTC commits happening in parallel that aren't contained within the atomic state being committed. So, it's safer to just get/put a reference for each CRTC being enabled or disabled in the new atomic state.
