6.1 Kernel GPU firmware update
-
After a certain update, video acceleration broke. So I decided to update to 6.1
gpu acceleration
sudo dmesg | grep panthor
create folder before copy
sudo cp /usr/lib/firmware/mali_csffw.bin /usr/lib/firmware/arm/mali/arch10.8/It's fix for sound thanks!
Comment out some alsa related in /etc/rc.local
Then boot into system. type alsamixer in terminal. F6 to select sound card.
Use " M" key to unmute left headphone mix and right headphone mix something like that. System is slow, because there is no hardware acceleartion.And disabled this service wirh errors
sudo systemctl disable qrtr-ns

@nathan said in 6.1 Kernel GPU firmware update:
before I switched to Linux 6.1 LTS with Panthor + newer Mesa).
Do you have mali acceleartion in OS?

@mainbord
The mali_csffw.bin path corresponding to the Panthor driver needs to be modified. The dmesg information will show the new loading path, and copying it on the system will enable GPU acceleration. -
@george
Thans! It is working!gpu acceleration
sudo dmesg | grep panthor
create folder before copy
sudo cp /usr/lib/firmware/mali_csffw.bin /usr/lib/firmware/arm/mali/arch10.8/ -
最近研究了一下内核还有panfrost相关的，说点个人想法和建议。
目前看来好像 coolpi 官方是想要尽快把设备支持推到主线内核里，包括 panthor 的支持，但是我又看到有种声音是说 panthor 的性能不如那个 panfork
而且很多人为了追求 panfork 的 gpu 性能也是搞出了 kernel 6.1 + panfork 的，比如
https://github.com/Joshua-Riek/ubuntu-rockchip/tree/kernel
还有
https://cool-pi.com/topic/588/bredos-for-the-cool-pi-4b所以这个 panfork 的性能真的差距那么大吗？panthor 我目前用感觉还好，不过还没抽空测试游戏什么的。

stock ubuntu, linux kernel 5.1 - 2000fps (panfork ??)
debian testing, linux kernel 6.1 - 1000fps (panthor ??)
software - 150 fps (cpu ??)With any GPU acceleration it's good.
Performance it's a second problem, first is - OpenGL ES 3.1
Good apps want open GL 4.5, example is blender or xonotic game. -
@mainbord
The efficiency of the Panthor driver is currently lower, and we look forward to future updates. -
@plumlis 请问你更换的什么网卡，我也想换，不知道会不会有什么障碍

@yfblock intel ax201
但前提是你需要编译内核，启用intel的驱动模块，并且把官方intel的固件拷贝进去就行了。coolpi默认屏蔽了intel
