Subject: Re: [PATCH v5 6/8] drm/panthor: Support GLB_REQ.STATE field for Mali-G1 GPUs
Hi Boris, Karunika,
I tested the diff on rk3588-rock-5b with and without
mali_csffw.bin installed.
With the firmware blob installed at
/lib/firmware/arm/mali/arch10.8/mali_csffw.bin, Panthor
initialises and probes successfully:

Without the firmware blob, the driver now fails probe with
