Dear maintener
For my own usage, I did make work the ASPEED ast-drm 1.15.1 video
driver on mainline kernel (6.13.0 + 6.13.1).
ASPEED video driver is availiable here:
https://www.aspeedtech.com/file/support/Linux_DRM_1.15.1_4.tar.gz
But it only work for LTS kernel
So I modify the DKMS package and I build a new Debian DKMS package
with the adapted source.
My patch can be find here :
https://xba.soartist.net/ast-drm_nba_20250211/nba-dkms/astdiff.patch
See the README:
https://xba.soartist.net/ast-drm_nba_20250211/nba-dkms/README
Using this new 'ast 1.15.1' driver, performance are amazing compared
to the 'ast' driver include in kernel tree, specially when using a
discrete GPU and offloading VULKAN / 3D on it but using AST VGA card
as the main video card and as the main and only video output (the
discrete GPU is used only for offloading 3D or for cuda/opencl)
You are using NVidia's proprietary driver, right? Did you reach out to
them wrt this problem? Or searched their support forums, online help,
etc? If so, what are the results?
Best regards

So to make things easier, I include the new 'ast 1.15.1' driver in
kernel tree as AST_NEW : linux-6.13.1-ast/drivers/gpu/drm/ast_new'
It's working fine as you can see on this video :
https://xba.soartist.net/ast-drm_nba_20250211/vulcan_nvidia_prime_render_offload_on_ast_vga_card.webm
I upload all the work I've done here :
https://xba.soartist.net/ast-drm_nba_20250211/
See the global README :
https://xba.soartist.net/ast-drm_nba_20250211/README
and the README in nba-kernel sub-directory :
https://xba.soartist.net/ast-drm_nba_20250211/nba-kernel/README
I'm not a developer so please let me know if I made the things the
right way and if this new 'ast 1.15.1' driver can be ported to
linux-next or linux-? ?
If you need more explanations, do not hesitate to contact me, I would
be happy to help
Kind regards
