* drm/i915: Fix scaler init during CRTC HW state readoutImre Deak2017-08-061-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 283d6860d64f5091565bf729b0a6d6af14ae6c27 upstream. The scaler allocation code depends on a non-zero default value for the crtc scaler_id, so make sure we initialize the scaler state accordingly even if the crtc is off. This fixes at least an initial YUV420 modeset (added in a follow-up patchset by Shashank) when booting with the screen off: after the initial HW readout and modeset which enables the scaler a subsequent modeset will disable the scaler which isn't properly allocated. This results in a funky HW state where the pipe scaler HW registers can't be modified and the normally black screen is grey and shifted to the right or jitters. The problem was revealed by Shashank's YUV420 patchset and first reported by Ville. v2: - In the stable tag also include versions which need backporting (Jani) Cc: Jani Nikula <jani.nikula@intel.com> Cc: Shashank Sharma <shashank.sharma@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Chandra Konduru <chandra.konduru@intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Reported-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Fixes: a1b2278e4dfc ("drm/i915: skylake panel fitting using shared scalers") Signed-off-by: Imre Deak <imre.deak@intel.com> Reviewed-by: Mahesh Kumar <mahesh1.kumar@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20170720112820.26816-1-imre.deak@intel.com Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> (cherry picked from commit 5fb9dadf336f3590c799e8cbde348215dccc2aa2) Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* drm/nouveau/bar/gf100: fix access to upper half of BAR2Ben Skeggs2017-08-061-1/+1
| | | | | | | | | | | | | | | | | | | commit 38bcb208f60924a031b9f809f7cd252ea4a94e5f upstream. Bit 30 being set causes the upper half of BAR2 to stay in physical mode, mapped over the end of VRAM, even when the rest of the BAR has been set to virtual mode. We inherited our initial value from RM, but I'm not aware of any reason we need to keep it that way. This fixes severe GPU hang/lockup issues revealed by Wayland on F26.

* drm/mst: Avoid processing partially received up/down message transactionsImre Deak2017-07-271-7/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 636c4c3e762b62aa93632c645ca65879285b16e3 upstream. Currently we may process up/down message transactions containing uninitialized data. This can happen if there was an error during the reception of any message in the transaction, but we happened to receive the last message correctly with the end-of-message flag set. To avoid this abort the reception of the transaction when the first error is detected, rejecting any messages until a message with the start-of-message flag is received (which will start a new transaction). This is also what the DP 1.4 spec 2.11.8.2 calls for in this case. In addtion this also prevents receiving bogus transactions without the first message with the the start-of-message flag set. v2: - unchanged v3: - git add the part that actually skips messages after an error in drm_dp_sideband_msg_build() Cc: Dave Airlie <airlied@redhat.com> Cc: Lyude <lyude@redhat.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Imre Deak <imre.deak@intel.com> Reviewed-by: Lyude <lyude@redhat.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20170719134632.13366-1-imre.deak@intel.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

One is in the thread which is started by vfio ioctl to do the iommu unmapping. The locking sequence is: down_read(&group_lock) ----> mutex_lock(&cached_lock) The other is in the vfio release thread which will unpin all the cached pages. The lock sequence is: mutex_lock(&cached_lock) ---> down_read(&group_lock) And, the cache_lock is used to protect the rb tree of the cache node and doing vfio unpin doesn't require this lock. Move the vfio unpin out of the cache_lock protected region. v2: - use for style instead of do{}while(1).

* drm/i915: Disable MSI for all pre-gen5Ville Syrjälä2017-07-271-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit ce3f7163e4ce8fd583dcb36b6ee6b81fd1b419ae upstream. We have pretty clear evidence that MSIs are getting lost on g4x and somehow the interrupt logic doesn't seem to recover from that state even if we try hard to clear the IIR. Disabling IER around the normal IIR clearing in the irq handler isn't sufficient to avoid this, so the problem really seems to be further up the interrupt chain. This should guarantee that there's always an edge if any IIR bits are set after the interrupt handler is done, which should normally guarantee that the CPU interrupt is generated. That approach seems to work perfectly on VLV/CHV, but apparently not on g4x. MSI is documented to be broken on 965gm at least. The chipset spec says MSI is defeatured because interrupts can be delayed or lost, which fits well with what we're seeing on g4x. Previously we've already disabled GMBUS interrupts on g4x because somehow GMBUS manages to raise legacy interrupts even when MSI is enabled. Since there's such widespread MSI breakahge all over in the pre-gen5 land let's just give up on MSI on these platforms. Seqno reporting might be negatively affected by this since the legcy interrupts aren't guaranteed to be ordered with the seqno writes, whereas MSI interrupts may be? But an occasioanlly missed seqno seems like a small price to pay for generally working interrupts.

* drm/radeon: Fix eDP for single-display iMac10,1 (v2)Mario Kleiner2017-07-271-2/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 564d8a2cf3abf16575af48bdc3e86e92ee8a617d upstream. The late 2009, 27 inch Apple iMac10,1 has an internal eDP display and an external Mini- Displayport output, driven by a DCE-3.2, RV730 Radeon Mobility HD-4670. The machine worked fine in a dual-display setup with eDP panel + externally connected HDMI or DVI-D digital display sink, connected via MiniDP to DVI or HDMI adapter. However, booting the machine single-display with only eDP panel results in a completely black display - even backlight powering off, as soon as the radeon modesetting driver loads. This patch fixes the single dispay eDP case by assigning encoders based on dig->linkb, similar to DCE-4+. While this should not be generally necessary (Alex: "...atom on normal boards should be able to handle any mapping."), Apple seems to use some special routing here. One remaining problem not solved by this patch is that an external Minidisplayport->DP sink does still not work on iMac10,1, whereas external DVI and HDMI sinks continue to work. The problem affects at least all tested kernels since Linux 3.13 - didn't test earlier kernels, so backporting to stable probably makes sense. v2: With the original patch from 2016, Alex was worried it will break other DCE3.2 systems. Use dmi_match() to apply this special encoder assignment only for the Apple iMac 10,1 from late 2009.

As we may end up clflushing, or doing the patch itself on the GPU, asynchronously we need to look at the implicit serialisation on obj->resv and hence need to disable EXEC_OBJECT_ASYNC for this object. If the user does trigger a stall for relocations, we make sure the stall is complete enough so that the batch is not submitted before we complete those relocations.

Since we stopped doing a full retire of the activity trackers for unbind, we need to explicitly retire each tracker.
