Add support for exported resources to virtgpu. This includes adding
support for the new virtgpu command as well as well as switching from
regular prime dma-bufs to virtio dma-bufs.

This change adds a new flavor of dma-bufs that can be used by virtio
drivers to share exported objects. A virtio dma-buf can be queried by
virtio drivers to obtain the UUID which identifies the underlying
exported object.

Considerably faster, and enough that calling cond_resched() every 4k

So every 128 pages is probably a reasonable compromise.

Without the cond_sched I suspect more of them are 3.0ms.
Not really a significant difference.
I guess the longer times are the scheduler looking for work?
I don't understand the extra traces - I'm guessing they are process switch
related.

(Oh, after I'd written a program to tidy up the raw ftrace output so schedviz
didn't barf on a trace that had wrapped.)
Is there anything in /proc (etc) that shows all the work queues and their
current

Da

extra instructions.

David Francis (6):
drm/dp_mst: Add PBN calculation for DSC modes
drm/dp_mst
is a DP feature new in DP v1.4, which exposes certain DPCD
registers on virtual ports.
ALso add a new quirk for Synatics MST hubs that support DSC
despite not supporting virtual DPCD.

s going to be a major rewrite.
MST DSC hardware is already on the market. It would be expedient to
merge the patches we need for Navi support sooner and update
drm_dp_mst_atomic_check when we're able to test it.

This field on drm_dp_mst_branch was never filled
Initialize it to zero when the list of ports is created.
When a port is added to the list, increment num_ports,
and when a port is removed from the list, decrement num_ports.

Instead of having drm_dp_dpcd_read/write and
drm_dp_mst_dpcd_read/write as entry points into the
aux code, have drm_dp_dpcd_read/write handle both.
This means that DRM drivers can make MST DPCD read/writes.

With DSC, bpp can be a multiple of 1/16, so
drm_dp_calc_pbn_mode is insufficient.
Add drm_dp_calc_pbn_mode_dsc, a function which is
the same as drm_dp_calc_pbn_mode, but the bpp is
in units of 1/16.

During MST mode enumeration, if a new dc_sink is created,
populate it with dsc caps as appropriate.
Use drm_dp_mst_dsc_caps_for_port to get the raw caps,
then parse them onto dc_sink with dc_dsc_parse_dsc_dpcd.
