hello
<gab>
sorry to intrude with a question out of the blue, but I've been looking everywhere for clues without finding any hint or answer
<gab>
I've been building a khadas-vim3 yocto image with meta-meson, but can't get anything on HDMI output after the kernel starts (output is working in mainline uboot)
<gab>
kmscube fails with 'failed to set mode: Unknown error 524' (which according to strace is an ENOTSUPP returned by DRM_IOCTL_MODE_SETCRTC on /dev/dri/card1)
<gab>
/sys/class/drm/card1-HDMI-A-1/status says 'connected' but /sys/class/drm/card1-HDMI-A-1/enabled says 'disabled'
<gab>
I tried on odroid N2 as well and 5.15 seems to have the same issue
<gab>
(currently building 5.10 for this machine to cross check)
<narmstrong>
`It seems that backporting commit 7cd70656d128 ("drm/bridge:
<narmstrong>
display-connector: implement bus fmts callbacks") fixes the problem
<narmstrong>
without reverting this commit.`
<gab>
oh right, I just saw this commit 10 minutes ago while looking at v5.15..v5.19 log in drivers/gpu/drm/meson/ ^^
<gab>
I'll just add it as a patch in bbappend then
<gab>
(same result with odroid N2 btw, hdmi works with 5.10)

narmstrong: right, applying 7cd70656d128 as a patch over v5.15.62 fixes it, thanks :)

btw while I'm here, did anyone try/manage to run optee_os with mainline u-boot on S922X/A311D ? (I saw a message saying "ERROR: Error initializing runtime service opteed_fast" in u-boot's logs)

It's possible to run the Amlogic OPTEE binary (32bit only snif) packaged in the FIP, at least it works fine with Linux OP-TEE support, never tried under u-boot
<gab>
I'd like to build my own optee-os
<narmstrong>
you can try :-p
<gab>
it should be living in bl32 right ?
<narmstrong>
yup
<narmstrong>
a basic port was done for the AXG SoCs
