2018-03-29drm/atomic-helper: Drop plane->fb references only for drm_atomic_helper_shutdown()Ville Syrjälä1-39/+39
drm_atomic_helper_shutdown() needs to release the reference held by plane->fb. Since commit 49d70aeaeca8 ("drm/atomic-helper: Fix leak in disable_all") we're doing that by calling drm_atomic_clean_old_fb() in drm_atomic_helper_disable_all(). This also leaves plane->fb == NULL afterwards. However, since drm_atomic_helper_disable_all() is also used by the i915 gpu reset code drm_atomic_helper_commit_duplicated_state() then has to undo the damage and put the correct plane->fb pointers back in (and also adjust the ref counts to match again as well). That approach doesn't work so well for load detection as nothing sets up the plane->old_fb pointers for us. This causes us to leak an extra reference for each plane->fb when drm_atomic_helper_commit_duplicated_state() calls drm_atomic_clean_old_fb() after load detection. To fix this let's call drm_atomic_clean_old_fb() only for drm_atomic_helper_shutdown() as that's the only time we need to actually drop the plane->fb references. In all the other cases (load detection, gpu reset) we want to leave plane->fb alone. v2: Don't inflict the clean_old_fbs bool to drivers (Daniel) v3: Squash in the revert and rewrite the commit msg (Daniel) Cc: martin.peres@free.fr Cc: chris@chris-wilson.co.uk Cc: Dave Airlie <airlied@gmail.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180322152313.6561-3-ville.syrjala@linux.intel.com Reviewed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> #pre-squash Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2018-03-28drm/i915/execlists: Reset ring registers on rebinding contextsChris Wilson1-0/+1
Tvrtko uncovered a fun issue with recovering from a wedge device. In his tests, he wedged the driver by injecting an unrecoverable hang whilst a batch was spinning. As we reset the gpu in the middle of the spinner, when resumed it would continue on from the next instruction in the ring and write it's breadcrumb. However, on wedging we updated our bookkeeping to indicate that the GPU had completed executing and would restart from after the breadcrumb; so the emission of the stale breadcrumb from before the reset came as a bit of a surprise. A simple fix is to when rebinding the context into the GPU, we update the ring register state in the context image to match our bookkeeping. We already have to update the RING_START and RING_TAIL, so updating RING_HEAD as well is trivial. This works because whenever we unbind the context, we keep the bookkeeping in check; and on wedging we unbind all contexts.

2018-03-28drm/udl: Get rid of dev->struct_mutex usageDaniel Vetter5-5/+11
It's only used to protect our page list, and only when we know we have a full reference. This means none of these code paths can ever race with the final unref, and hence we do not need dev->struct_mutex serialization and can simply switch to our own locking. For more context the only magic the locked gem_free_object provides is that it prevents concurrent final unref (and destruction) of gem objects while anyone is holding dev->struct_mutex. This was used by i915 (and other drivers) to implement eviction handling with less headaches.

2018-03-28drm/i915/gvt: Make MI_USER_INTERRUPT nop in cmd parserZhipeng Gong1-0/+1
GVT-g dispatches request to host i915 and depends on i915 notify ring interrupt mechanism to check completion of request. For now MI_USER_INTERRUPT in guest requests is passed through in GVT-g cmd parser and i915 does not use it, which causes unnecessary interrupt handling in i915. On the other hand, if several requests from guest are combined into one request in and contain MI_USER_INTERRUPT in the middle of combined request. GVT-g still has to wait on the whole request to complete to inject user interrupts to guest. This patch makes all the MI_USER_INTERRUPT nop to save some interrupt handling. Here is test result to run glmark2 on guest for 10 seconds: host master interrupts number is reduced from 16021 to 11162 host user interrupts number is reduced from 7936 to 3536 v2: - revise commit message.
