GPU not detected by panfrost kernel module

#1

Hi,
loading the panfrost DRM kernel module results in

panfrost fb000000.gpu: clock rate = 200000000
panfrost fb000000.gpu: Looking up mali-supply from device tree
panfrost fb000000.gpu: opp_parse_supplies: Invalid number of elements in opp-microvolt-property (6) with supplies (1)
panfrost fb000000.gpu: _of_add_opp_table_v2: Failed to add OPP, -22
panfrost fb000000.gpu: devfreq init failed -22
panfrost fb000000.gpu: Fatal error during GPU init
panfrost fb000000.gpu: probe of fb000000.gpu failed with error -22

I have all the G610 bits from panfork userland - but apparently something is still missing on the kernel side (currently using stable-5.10-rock5 – wouldn’t mind upgrading to mainline at all, but looks like GPU support isn’t there yet - at least not mentioned in the devicetree).

Any ideas?

I think you have to follow mali blobs for x11.

Do anyone get Solution ?
Even the same problem I am facing in kernel version 6.1 in Rk3588 with Mali GPU G610 MP4 Valhall.

You are using mesa 23.2.1, so rk3588 mali g610 is not supported. You have to use mesa up to 24.1.
