Noticed this while working on adding a drm_dp_decode_sideband_req(). DP_POWER_DOWN_PHY/DP_POWER_UP_PHY both use the same struct as DP_ENUM_PATH_RESOURCES, so we can just combine their cases. Changes since v2: * Fix commit message Signed-off-by:

Yes, apparently we've been testing this for every single driver load for quite a long time now. At least that means our PBN calculation is solid!

We can reduce the critical section in vkms_vblank_simulate under output->lock quite a lot: - hrtimer_forward_now just needs to be ordered correctly wrt drm_crtc_handle_vblank. We already access the hrtimer timestamp without locks. While auditing that I noticed that we don't correctly annotate the read there, so sprinkle a READ_ONCE to make sure the compiler doesn't do anything foolish. - drm_crtc_handle_vblank must stay under the lock to avoid races with drm_crtc_arm_vblank_event. - The access to vkms_ouptut->crc_state also must stay under the lock. - next problem is making sure the output->state structure doesn't get freed too early. First we rely on a given hrtimer being serialized: If we call drm_crtc_handle_vblank, then we are guaranteed that the previous call to vkms_vblank_simulate has completed. The other side of the coin is that the atomic updates waits for the vblank to happen before it releases the old state. Both taken together means that by the time the atomic update releases the old state, the hrtimer won't access it anymore (it might be accessing the new state at the same time, but that's ok). - state is invariant, except the few fields separate protected by state->crc_lock. So no need to hold the lock for that. - finally the queue_work. We need to make sure there's no races with the flush_work, i.e. when we call flush_work we need to guarantee that the hrtimer can't requeue the work again. This is guaranteed by the same vblank/hrtimer ordering guarantees like the reasoning above why state won't be freed too early: flush_work on the old state is called after wait_for_flip_done in the atomic commit code. Therefore we can also move everything after the output->crc_state out of the critical section. Motivated by suggestions from Rodrigo. Signed-off-by:

Noticed while reviewing code. I'm not sure whether this might or might not explain some of the missed vblank hilarity we've been seeing on various drivers (but those got tracked down to driver issues, at least mostly). I think those all go through the vblank completion event, which has unconditional barriers - it always takes the spinlock. Therefore no cc stable. v2: - Barrriers are hard, put them in in the right order (Chris). - Improve the comments a bit. v3: Ville noticed that on 32bit we might be breaking up the load/stores, now that the vblank counter has been switched over to be 64 bit. Fix that up by switching to atomic64_t. This this happens so rarely in practice I figured no need to cc: stable ...

Store the timestamp of the current vblank in the new field 'time' of the vblank trace event. If the timestamp is calculated by a driver that supports high-precision vblank timing, set the field 'high-prec' to 'true'. User space can now access actual hardware vblank times via the tracing infrastructure. Tracing applications (such as GPUVis, see [0] for related discussion), can use the newly added information to conduct a more accurate analysis of display timing. v2 Fix author name (missing last name) [0] https://github.com/mikesart/gpuvis/issues/30Reviewed-by:

We are about to add a drm_bridge_state that inherits from drm_private_state which is defined in drm_atomic.h. Problem is, drm_atomic.h includes drm_crtc.h which in turn includes drm_bridge.h, leading to "drm_private_state has incomplete type" error. Let's force all users of the drm_bridge API to explicitly include drm_bridge.h. Signed-off-by:

Split virtqueue_kick() call into virtqueue_kick_prepare(), which requires serialization, and virtqueue_notify(), which does not. Move the virtqueue_notify() call out of the critical section protected by the queue lock. This avoids triggering a vmexit while holding the lock and thereby fixes a rather bad spinlock contention.

This code will likely crash if we try to do a zero byte write. The code looks like this: /* strip trailing whitespace */ for (i = count - 1; i > 0; i--) if (isspace(buf[i])) ... We're writing zero bytes so count = 0. You would think that "count - 1" would be negative one, but because "i" is unsigned it is a large positive numer instead. The "i > 0" condition is true and the "buf[i]" access will be out of bounds. The fix is to make "i" signed and now everything works as expected. The upper bound of "count" is capped in __kernel_write() at MAX_RW_COUNT so we don't have to worry about it being higher than INT_MAX.

Instead of requiring all drivers to set the dev and funcs fields of drm_panel manually after calling drm_panel_init(), pass the data as arguments to the function. This simplifies the panel drivers, and will help future refactoring when adding new arguments to drm_panel_init(). The panel drivers have been updated with the following Coccinelle semantic patch, with manual inspection to verify that no call to drm_panel_init() with a single argument still exists. @@ expression panel; expression device; identifier ops; @@ drm_panel_init(&panel + , device, &ops ); ...

While newer kbase include only the numbers of errata, older kbase releases included one-line descriptions for each errata, which is useful for those working on the driver. Import these descriptions. Most are from kbase verbatim; a few I edited for clarity. v2: Wrote a description for the workaround of an issue whose cause is still unknown (Stephen). Errata which pertain to newer models unsupported by the mainline driver, for which Arm has not yet released errata information, have been removed from the issue list as the kernel need not concern itself with these. v3: Readded errata not yet handled, adding descriptions based on the workarounds in the latest kbase release.
