2018-12-20drm/ioctl: Fix Spectre v1 vulnerabilitiesGustavo A. R. Silva
nr is indirectly controlled by user-space, hence leading to a potential exploitation of the Spectre variant 1 vulnerability. This issue was detected with the help of Smatch: drivers/gpu/drm/drm_ioctl.c:805 drm_ioctl() warn: potential spectre issue 'dev->driver->ioctls' [r] drivers/gpu/drm/drm_ioctl.c:810 drm_ioctl() warn: potential spectre issue 'drm_ioctls' [r] (local cap) drivers/gpu/drm/drm_ioctl.c:892 drm_ioctl_flags() warn: potential spectre issue 'drm_ioctls' [r] (local cap) Fix this by sanitizing nr before using it to index dev->driver->ioctls and drm_ioctls. Notice that given that speculation windows are large, the policy is to kill the speculation on the first load and not worry if it can be completed with a dependent load/store [1].

Mostly just initial support for Turing TU104/TU106 chipsets. Support for TU102 is missing as I don't yet have HW, but it should be trivial to add in later in the merge window (in theory). It's a bit of a rough first pass that'll get improved in future releases as a finish figuring out some of the other HW changes, but it's good enough as it stands for modesetting and suspend/resume etc. Acceleration bring-up is incomplete due to NVIDIA not yet having provided FW images for me to use, though command submission and copy engines are functional already.

2018-12-12drm/amd/display: Add fast path for cursor plane updatesNicholas Kazlauskas
[Why] Legacy cursor plane updates from drm helpers go through the full atomic codepath. A high volume of cursor updates through this slow code path can cause subsequent page-flips to skip vblank intervals since each individual update is slow. This problem is particularly noticeable for the compton compositor. [How] A fast path for cursor plane updates is added by using DRM asynchronous commit support provided by async_check and async_update. These don't do a full state/flip_done dependency stall and they don't block other commit work. However, DC still expects itself to be single-threaded for anything that can issue register writes. Screen corruption or hangs can occur if write sequences overlap. Every call that potentially perform register writes needs to be guarded for asynchronous updates to work. The dc_lock mutex was added for this.

2018-12-12drm/i915: Flush GPU relocs harder for gen3Chris Wilson
Adding an extra MI_STORE_DWORD_IMM to the gpu relocation path for gen3 was good, but still not good enough. To survive 24+ hours under test we needed to perform not one, not two but three extra store-dw. Doing so for each GPU relocation was a little unsightly and since we need to worry about userspace hitting the same issues, we should apply the dummy store-dw into the EMIT_FLUSH.

2018-12-12drm/i915: Allocate a common scratch pageChris Wilson
Currently we allocate a scratch page for each engine, but since we only ever write into it for post-sync operations, it is not exposed to userspace nor do we care for coherency. As we then do not care about its contents, we can use one page for all, reducing our allocations and avoid complications by not assuming per-engine isolation. For later use, it simplifies engine initialisation (by removing the allocation that required struct_mutex!) and means that we can always rely on there being a scratch page. v2: Check that we allocated a large enough scratch for I830 w/a Fixes: 06e562e7f515 ("drm/i915/ringbuffer: Delay after EMIT_INVALIDATE for gen4/gen5") # v4.18.20 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=108850 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> Reviewed-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181204141522.13640-1-chris@chris-wilson.co.uk Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: <stable@vger.kernel.org> # v4.18.20+ (cherry picked from commit 5179749925933575a67f9d8f16d0cc204f98a29f) [Joonas: Use new function in gen9_init_indirectctx_bb too] Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com>
2018-12-12drm/i915/execlists: Apply a full mb before execution for BraswellChris Wilson
Braswell is really picky about having our writes posted to memory before we execute or else the GPU may see stale values. A wmb() is insufficient as it only ensures the writes are visible to other cores, we need a full mb() to ensure the writes are in memory and visible to the GPU. The most frequent failure in flushing before execution is that we see stale PTE values and execute the wrong pages.

This reverts commit 91b66c47ba3468f7882ea4a84d5e0e0c186b638f. Forcing RMX_ASPECT as default uses the preferred/native mode's timings for any mode the user selects and scales the image. This provides a a consistently nicer result in the case where the selected mode's refresh rate matches the native mode's refresh but this isn't always the case. For example, if the monitor is 1080p@144Hz and the preferred mode is 60Hz then even if the user selects 1080p@144Hz as their selected mode they'll get 1080p@60Hz.

2018-12-11drm/msm/dpu: Cleanup the debugfs functionsJordan Crouse
Do some debugfs cleanups from across the DPU driver. The DRM destroy functions will do a recursive delete on the entire debugfs node so there is no need to store dentry pointers for the debugfs files that are persistent for the life of the driver. This also means that the destroy functions can go away too. Also, use standard API functions where applicable instead of using hand written code. v3: No changes v2: Add more code; most of the dpu debugfs files should be addressed now.

2018-12-11drm/msm/dpu: Remove dpu_irq and unused functionsJordan Crouse
dpu_irq.c does some unneeded checks and passes control to dpu_core_irq.c The simple functions can be defined in the same file where we use them and the files and their associated hangers on can be deleted.

2018-12-11drm/msm/dpu: Cleanup callers of dpu_hw_blk_initJordan Crouse
Outside of superfluous parameter checks the dpu_hw_blk_init() doesn't have any failure paths.

2018-12-11drm/msm: dpu: Separate crtc assignment from vblank enableSean Paul
Instead of assigning/clearing the crtc on vblank enable/disable, we can just assign and clear the crtc on modeset. That allows us to just toggle the encoder's vblank interrupts on vblank_enable. So why is this important? Previously the driver was using the legacy pointers to assign/clear the crtc. Legacy pointers are cleared _after_ disabling the hardware, so the legacy pointer was valid during vblank_disable, but that's not something we should rely on. Instead of relying on the core ordering the legacy pointer assignments just so, we'll assign the crtc in dpu_crtc enable/disable. This is the only place that mapping can change, so we're covered there. We're also taking advantage of drm_crtc_vblank_on/off. By using this, we ensure that vblank_enable/disable can never be called while the crtc is off (which means the assigned crtc will always be valid). As such, we don't need to use modeset locks or the crtc_lock in the vblank_enable/disable routine to be sure state is consistent. ...I think.

2018-12-11drm/msm: dpu: Remove vblank_callback from encoderSean Paul
The indirection of registering a callback and opaque pointer isn't reall useful when there's only one callsite. So instead of having the vblank_cb registration, just give encoder a crtc and let it directly call the vblank handler. In a later patch, we'll make use of this further.

2018-12-11drm/msm: dpu: Remove crtc_lock from setup_mixersSean Paul
I think the intention here was to protect the enc->crtc access, but that's insufficient to avoid enc->crtc changing. Fortunately we're already holding the modeset lock when this is called (from atomic_check), so remove the crtc_lock and add a modeset lock check. While we're at it, use the encoder mask from crtc state instead of legacy pointer.

2018-12-11drm/msm: dpu: Move pm_runtime_(get|put) from vblank_enableSean Paul
There are 4 times that _dpu_crtc_vblank_enable_no_lock() is called: 1- crtc enable 2- crtc disable 3- crtc vblank enable 4- crtc vblank disable When we enable or disable the crtc, we call drm_crtc_vblank_on and drm_crtc_vblank_off respectively. That will gate vblank enables and disables to only being called when the crtc is active. That means that we can just enable/disable pm runtime in crtc enable/disable. This will be beneficial in trying to eliminate blocking calls from the vblank call chain.
