I.e. if you want to add the necessary patches indicated above into meta-rockchip so that a working image can be generated without any additional dependencies on other layers. Would that be possible?

Yes, but I don't want to :) Basically, this was just if someone wanted to tinker before it was merged into OE-Core. I don't think it makes sense to add the necessary patches/bbappends in meta-rockchip for the master branch, it's duplicating efforts. However, I plan on backporting the mesa recipe to scarthgap once it's merged upstream, that would probably have its place in meta-rockchip (and if not, I'll have it in my layer anyway :) ). The issue right now is that the mesa bump is just not something I can achieve without substantial effort as I know nothing about meson, mesa and graphical stuff and the issues I encountered were a bit too hairy for me :/ I hope someone can have a look at it, but for now I'll have to stop here. I will likely have to do this by the end of the year/beginning of next year when we migrate our customer base to upstream kernel, but I hope that we'll have this bumped by someone else before. Basically, you can ignore this until I send another version :) Cheers, Quentin
Panthor is the open-source implementation for the Arm GPU Valhall series both in the Linux kernel and Mesa userspace. In the latter, the panfrost "driver" is actually handling this version of the Arm GPU. One therefore needs to enable kmsro and panfrost in PACKAGECONFIG to be able to use this open-source implementation. The open-source implementation still requires a proprietary blob which is running on the GPU: mali_csffw.bin. Note that the closed-source implementation (libmali and vendor kernel drivers) also require this blob. Right now, we're still missing a linux-yocto v6.10+ to be able to test this with everything upstream in Yocto/OE, but I was able to successfully test this with kmscube on a downstream kernel (6.6 + backported patches for GPU and custom patches for DSI support) on an RK3588 Tiger. Additionally, the following patch series is required from OE-Core: https://lore.kernel.org/openembedded-core/20240531-panthor-v1-0-1a76fd752c1b@cherry.de/T/#t Signed-off-by: Quentin Schulz <quentin.schulz@cherry.de> --- Quentin Schulz (2): mesa: enable Panfrost support for RK3588(S) mesa: recommend mali csffw firmware package for mesa-megadriver for RK3588s recipes-graphics/mesa/mesa_%.bbappend | 3 +++ 1 file changed, 3 insertions(+) --- base-commit: 3381d6af6eabfb532da16863b785a95abba6b9e8 change-id: 20240531-mesa-panthor-9c31ca1aa31f Best regards,
