When run a weston 10.0.0:

I got the following error:
drm_atomic_check_only [PLANE:31:Smart0-win0] CRTC set but no FB
Can you please start Weston with --logger-scopes=log,drm-backend and
attach the output?
Please see the weston ouput here[0]
Are you running with musl perhaps?
Do you mean the C library? I chose uClib-ng in buildroot, not use musl.
Either way, please make sure your
libdrm build includes commit 79fa377c8bdc84fde99c6a6ac17e554971c617be.
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.
Cheers,
Daniel
