Hi,
This is the v6 series to introduce i.MX8qm/qxp Display Processing Unit(DPU)

DPU is comprised of a blit engine for 2D graphics, a display controller
and a command sequencer. Outside of DPU, optional prefetch engines can
fetch data from memory prior to some DPU fetchunits of blit
The meta-schema recently gained a definition for the common -supply$

This patch allows statistics to be enabled for each DMA-BUF in
sysfs by enabling the config CONFIG_DMABUF_SYSFS_STATS.
The following stats will be exposed by the interface:
/sys/kernel/dmabuf/buffers//exporter_name
/sys/kernel/dmabuf/buffers//size
/sys/kernel/dmabuf/buffers//attachments//device

The OneGX1 Pro has a fairly unique combination of generic strings,
but we additionally match on the BIOS date just to be safe.

Ok, so I built drm-intel-next and I was able to reproduce the buid

I still have no idea what's going on here.
The KASAN messages from the DC code are completely unrelated.

Hi Dave & Daniel,
Here is the final PR for v5.12.
One more fix for the clear residuals security mitigation.

Hi all,
Finally gotten around to refreshing all the various fence anntotions I've
hast last summer. Or well parts of it:
- entire amdgpu and drm/scheduler annotations postponed for now, because
there's way too many splats in there that need some work
- in recent patches I've seen quite a few d
This is needed to signal the fences from page flips, annotate it
accordingly. We need to annotate entire timer callback since if we get
stuck anywhere in there, then the timer stops, and hence fences stop.
Just annotating the top part that does the vblank handling isn't
enough.
Tested-by: Melissa
This is a bit disappointing since we need to split the annotations
over all the different parts.
I was considering just leaking the critical section into the
->atomic_commit_tail callback of each driver. But that would mean we
need to pass the fence_cookie into each driver (there's a total of 13
i
This is rather overkill since currently all drivers call this from
hardirq (or at least timers). But maybe in the future we're going to
have thread irq handlers and what not, doesn't hurt to be prepared.
Plus this is an easy start for sprinkling these fence annotations into
shared code.

Again needs to be put right after the call to

can hold up a subsequent atomic commit.

One of these drivers that predates the nonblocking support in helpers,
and hand-rolled its own thing. Entirely not anything specific here, we
can just delete it all and replace it with the helper version.
Could also perhaps use the drm_mode_config_helper_suspend/resume
stuff, for another few lines
drm_atomic_helper_commit_hw_done() is the last thing (no plane cleanup
apparrently), so it's the entire function. And a nice comment
explaining why thw wait_for_flip_done is ahead, unlike the usual
sequence.
Aside, I think since the atomic helpers do track plane disabling now
separately this might
Like the helpers, nothing special. Well except not, because we the
critical section extends until after hw_done(), since that's the last

allowed to call dma_fence_wai
