Let's provide the proper link from the touchscreen to the panel on
trogdor devices where the touchscreen support it. This allows the OS
to power sequence the touchscreen more properly.
For the most part, this is just expected to marginally improve power
consumption while the screen is off. However

Hi all,
I am working to implement virtgpu S3 function on Xen.
Currently on Xen, if we start a guest who enables virtgpu, and then
run "echo mem > /sys/power/state" to suspend guest. And run
"sudo xl trigger s3resume" to resume guest. We can find that
the guest kernel comes back, but the display
This patch solves two problem:
First, when we suspended guest VM, it called into Qemu to call
virtio_reset->__virtio_queue_reset, this cleared all virtuqueue
information of virtgpu on Qemu end. As a result, after guest
resumed, guest sended ctrl/cursor requests to Qemu through
virtqueue, but Qemu

If I understand correctly, drm_sched_entity_kill_jobs_cb() is supposed
to wait on all the external dependencies (those added to
drm_sched_job::dependencies) before signaling the job finished fence.
This is done this way to prevent jobs depending on these canceled jobs
from considering the resources
