Dear maintener
I did include ast-drm driver version 1.15.1 (in replacement of version
0.1.0) on the new mainline kernel too (6.14.0-rc2) and I issue a new
dkms patch
Last DKMS patch had been sucessfully tested on mainline.
And last ast.ko version 1.15.1 included in linux tree had also been
sucessfully tested
Online directory is updated with :
- new DKMS patch
- new DKMS srouces
- new DKMS debian package
- new tarball of mainline included ast_new ported in kernel tree
- new kernel debian package (mainline with ast_new)
NB: online directory is here:
https://xba.soartist.net/ast-drm_nba_20250211/
Please let me know what I should do to see this change in linux-next
Thanks for help
Kind regards

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)
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
