1 year ago Hello.
I thought it was on.
CONFIG_DRM_PANFROST=y never selected it manually, but using the menuconfig.
CONFIG_DRM_MALI_DISPLAY is for a different mali device family.
Probably some other items should be selected too. This is from other config where X.org should works

Hello my friend.
I've almost completed my project : to virtualize FreeBSD on top of Linux with qemu-kvm on the ARM Chromebook. Everything works great. Even the network on the vm. One last task needs to be accomplished. To be able to use the panfrost graphic driver on the linux distro that I have chosen and where I have configured everything : Devuan 5. I would like to understand what's the fulll procedure to enable the MALI driver and to make it work. What I did right now is to enable the MALI driver inside the kernel that I'm using (vers. 5.4.257).
The only parameter that I've found on the kernel config file related to MALI is the following :
CONFIG_DRM_MALI_DISPLAY=y
and I set it to y. Until here it was easy. What I don't understand is after enabling that parameter,it will work automatically or if I should make an additional configuration and which kind of configuration it needs. Thanks.
