2020-02-11drm/i915/gem: Store mmap_offsets in an rbtree rather than a plain listChris Wilson3-29/+85
Currently we create a new mmap_offset for every call to mmap_offset_ioctl. This exposes ourselves to an abusive client that may simply create new mmap_offsets ad infinitum, which will exhaust physical memory and the virtual address space. In addition to the exhaustion, a very long linear list of mmap_offsets causes other clients using the object to incur long list walks -- these long lists can also be generated by simply having many clients generate their own mmap_offset. However, we can simply use the drm_vma_node itself to manage the file association (allow/revoke) dropping our need to keep an mmo per-file. Then if we keep a small rbtree of per-type mmap_offsets, we can lookup duplicate requests quickly.

2020-02-10drm/i915: Make a copy of the ggtt view for slave planeVille Syrjälä1-0/+1
intel_prepare_plane_fb() will always pin plane_state->hw.fb whenever it is present. We copy that from the master plane to the slave plane, but we fail to copy the corresponding ggtt view. Thus when it comes time to pin the slave plane's fb we use some stale ggtt view left over from the last time the plane was used as a non-slave plane. If that previous use involved 90/270 degree rotation or remapping we'll try to shuffle the pages of the new fb around accordingingly. However the new fb may be backed by a bo with less pages than what the ggtt view rotation/remapped info requires, and so we we trip a GEM_BUG(). Steps to reproduce on icl: 1. plane 1: whatever plane 6: largish !NV12 fb + 90 degree rotation 2. plane 1: smallish NV12 fb plane 6: make invisible so it gets slaved to plane 1 3.

2020-02-09drm/i915: Fix post-fastset modeset check for port syncVille Syrjälä1-26/+17
The post-fastset "does anyone still need a full modeset?" for port sync looks busted. The outer loop bails out of a full modeset is still needed by the current crtc, and then we skip forcing a full modeset on the related crtcs. That's totally the opposite of what we want. The MST path has the logic mostly the other way around so it looks correct. To fix the port sync case let's follow the MST logic for both. So, if the current crtc already needs a modeset we do nothing. otherwise we check if any of the related crtcs needs a modeset, and if so we force a full modeset for the current crtc. And while at let's change the else if to a plain if to so we don't have needless coupling between the MST and port sync checks.

2020-02-06drm/tegra: Reuse IOVA mapping where possibleThierry Reding3-23/+63
This partially reverts the DMA API support that was recently merged because it was causing performance regressions on older Tegra devices. Unfortunately, the cache maintenance performed by dma_map_sg() and dma_unmap_sg() causes performance to drop by a factor of 10. The right solution for this would be to cache mappings for buffers per consumer device, but that's a bit involved. Instead, we simply revert to the old behaviour of sharing IOVA mappings when we know that devices can do so (i.e. they share the same IOMMU domain).

2020-02-04drm/amd/dm/mst: Ignore payload update failuresLyude Paul1-9/+4
Disabling a display on MST can potentially happen after the entire MST topology has been removed, which means that we can't communicate with the topology at all in this scenario. Likewise, this also means that we can't properly update payloads on the topology and as such, it's a good idea to ignore payload update failures when disabling displays. Currently, amdgpu makes the mistake of halting the payload update process when any payload update failures occur, resulting in leaving DC's local copies of the payload tables out of date.

The sdma_queue_count increment should be done before execute_queues_cpsch(), which calls pm_calc_rlib_size() where sdma_queue_count is used to calculate whether over_subscription is triggered. With the previous code, when a SDMA queue is created, compute_queue_count in pm_calc_rlib_size() is one more than the actual compute queue number, because the queue_count has been incremented while sdma_queue_count has not.

2020-02-04drm/amd/display: Only enable cursor on pipes that need itNicholas Kazlauskas1-0/+30
[Why] In current code we're essentially drawing the cursor on every pipe that contains it. This only works when the planes have the same scaling for src to dest rect, otherwise we'll get "double cursor" where one cursor is incorrectly filtered and offset from the real position. [How] Without dedicated cursor planes on DCN we require at least one pipe that matches the scaling of the current timing. This is an optimization and workaround for the most common case where the top-most plane is not scaled but the bottom-most plane is scaled. Whenever a pipe has a parent pipe in the blending tree whose recout fully contains the current pipe we can disable the pipe. This only applies when the pipe is actually visible of course.

2020-02-03drm/nouveau/kms/gv100-: avoid sending a core update until the first modesetBen Skeggs2-6/+2

2020-01-31drm/tegra: sor: Initialize runtime PM before useThierry Reding1-15/+17
Commit fd67e9c6ed5a ("drm/tegra: Do not implement runtime PM") replaced the generic runtime PM usage by a host1x bus-specific implementation in order to work around some assumptions baked into runtime PM that are in conflict with the requirements in the Tegra DRM driver. Unfortunately the new runtime PM callbacks are not setup yet at the time when the SOR driver first needs to resume the device to register the SOR pad clock, and accesses to register will cause the system to hang. Note that this only happens on Tegra124 and Tegra210 because those are the only SoCs where the SOR pad clock is registered from the SOR driver. Later generations use a SOR pad clock provided by the BPMP. Fix this by moving the registration of the SOR pad clock after the host1x client has been registered. That's somewhat suboptimal because this could potentially, though it's very unlikely, cause the Tegra DRM to be probed if the SOR happens to be the last subdevice to register, only to be immediately removed again if the SOR pad output clock fails to register. That's just a minor annoyance, though, and doesn't justify implementing a workaround. Fixes: fd67e9c6ed5a ("drm/tegra: Do not implement runtime PM") Signed-off-by: Thierry Reding <treding@nvidia.com>
