From: Andy Yan <andy.yan@rock-chips.com>

The VOP2 unit is found on Rockchip SoCs beginning with rk3566/rk3568.
It replaces the VOP unit found in the older Rockchip SoCs.

This driver has been derived from the downstream Rockchip Kernel and
heavily modified:

- All nonstandard DRM properties have been removed
- dropped struct vop2_plane_state and pass around less data between
  functions
- Dropped all DRM_FORMAT_* not known on upstream
- rework register access to get rid of excessively used macros
- Drop all waiting for framesyncs

The driver is tested with HDMI and MIPI-DSI display on a RK3568-EVB
board. Overlay support is tested with the modetest utility. AFBC support
on the cluster windows is tested with weston-simple-dmabuf-egl on
weston using the (yet to be upstreamed) panfrost driver support.

When run a weston 10.0.0:

  # export XDG_RUNTIME_DIR=/tmp
  # weston --backend=drm-backend.so --use-pixma --tty=2 
--continue=without-input

I got the following error:

drm_atomic_check_only [PLANE:31:Smart0-win0] CRTC set but no FB

...atomic core check failed.


weston: [atomic] couldn't commit new state: Resource temporarily unavailable

repaint-flush faild: Resource temporarily unavaiable

this is no display on hdmi.

I have to mask the the "start with plane disabled" logic in weston to 
get it run correctly.

  -1066,14 +1066,14 @@ drm_pending_state_apply_atomic(struct 
drm_pending_state *pending_state,
                 break;
         }

-       if (b->state_invalid) {
+       if (0/*b->state_invalid*/) {
                 struct weston_head *head_base;
                 struct drm_head *head;
                 struct drm_crtc *crtc;
                 uint32_t connector_id;
                 int err;


I am not sure if this is a drm driver or weston problem.

I used weston 9.0.90 during testing. I'll try to reproduce the issue
with weston 10.

Could you maybe have a look at the HCLK issue we are discussing? This
thread could use some input from someone who has contact to the hardware
guys.

Can you please start Weston with --logger-scopes=log,drm-backend and
attach the output?

Are you running with musl perhaps? Either way, please make sure your
libdrm build includes commit 79fa377c8bdc84fde99c6a6ac17e554971c617be.

Do you mean the C library? I chose uClib-ng in buildroot, not use musl.

The upstream buildroot use libdrm2.4.109, this commit[0] if from 
libdrm2.4.110

I cherry-pick this patch to my local libdrm, but has no effect, still 
has "atomic: couldn't commit new state" error.

I have do a search in libdrm and weston, but find no one call 
drmModeAtomicMerge, is that right?

With your patch applied from libdrm2.4.110, I do a make clean for 
buidlroot, than build it again,  That's take effect.

I can see only the second value (non-zero FB) of plane 31 commit to the 
kernel. So this is works.

Maybe the buidroot should update libdrm package.

Thank you.

Hi Daniel:

   Remember you said our downstream vop2 driver is very slow on weston.

Would you please share the case you run ? or how can i test frame rate 
on weston?

We were able to observe this by just using either waylandsink (using
dmabuf from the V4L2 rkvdec/rkvpu drivers), or even weston-simple-egl.
I have not been able to do a full review of Sascha's submission, but
from what I've seen of it, it should have fixed those issues. (I don't
have RK3568 hardware to hand anymore.)

Cheers,
Daniel
