musicPi Posted May 25, 2020 Posted May 25, 2020 (edited) Hello there, I'm new to this Forum, so please I been trying to run Kodi as standalone music station with Buster minimal and Kodi 17 on it. This system boots very quick and I've been quite happy when I got kodi starting successfully, but it's very slow. It takes several seconds to switch from one menu item to the next. Next I tried to speed up the graphics using this instructionshttps://forum.armbian.com/topic/1420-opengl-on-mali-gpu-bananapi-orangepi-pc-etc/ http://wiki.lemaker.org/BananaPro/Pi:GPU But failed with xorg saying: Quote modprobe: FATAL: Module g2d_23 not found in directory /lib/modules/5.4.35-sunxi modprobe: FATAL: Module mali not found in directory /lib/modules/5.4.35-sunxi modprobe: FATAL: Module mali_drm not found in directory /lib/modules/5.4.35-sunxi modprobe: FATAL: Module sunxi_cedar_mod not found in directory /lib/modules/5.4.35-sunxi SunxiMaliDRI2_Init: drmOpen failed! xf86: found device 0 xinit: connection to X server lost /etc/X11/xorg.conf: Quote Section "Monitor" Identifier "Monitor0" Option "DPMS" "false" EndSection Section "ServerFlags" Option "Blanktime" "0" Option "StandbyTime" "0" Option "SuspendTime" "0" Option "Offtime" "0" EndSection Section "Device" Identifier "Mali-400" Driver "fbturbo" Option "fbdev" "/dev/fb0" Option "SwapbuffersWait" "true" Option "AccelMethod" "G2D" Option "DRI2" "true" EndSection Section "Screen" Identifier "Screen0" Device "Mali-400" Monitor "Monitor0" EndSection There is no /dev/mali, /dev/ump or /dev/disp device available. Modules ump, mali, mali_drm are not loaded, but I saw lima drivers were active: Quote $ lsmod ... lima 36864 1 brcmfmac 167936 0 gpu_sched 24576 1 lima ... I hope we can get this working either via mali or using lima driver. Thanks in advance für your help! regards Edited May 25, 2020 by musicPi

They have little in common. Lima driver is integrated in Armbian kernel for about 1-2 years, starting with 4.19.y ... how to make it work. Do some forum searching - you are probably not the only one.
Igor Posted May 25, 2020 Posted May 25, 2020 We also tried to integrate Mali https://github.com/armbian/build/pull/1409 but falied due to lack of time / resources.
ning Posted May 30, 2020 Posted May 30, 2020 I don't think integrate mali is a good choice, mali kernel driver is difficult to integrate, due to nowadays there is completely different display driver in mainline linux, and mali userspace binary driver only provides opengl_es2, lack of opengl, that means only gles programs can use mali gpu, desktop UI rendering still software. if not build a special OS like lakka, desktop OS good to choose lima/panfrost for gpu driver.
