Hi,
Has anyone had success with the ASPEED Xorg driver? I have tried several =
versions (in ports, from ASPEED directly, from freedesktop.org etc) and =
they all hang trying to read DRAM information in ASTGetDRAMInfo. I am =
running FreeBSD 12 on a Supermicro X11SSH-F.
The hang is here:
do {
;
} while (*(volatile ULONG *) (pAST->MMIOVirtualAddr + 0x10000) !=3D =
0x01);
I patched it to use some hard coded values I extracted from an old =
system where it worked and it does run but the performance is quite =
terrible.
I've also tried scfb (performance is so so but it's stuck and 1024x768) =
and VESA (runs at 1920x1080 but the performance is intolerable).
I'm not expecting mind blowing performance but even the best performing =
option above is quite painful to use. These systems are mostly =
unattended but the bad performance does make the setup and test during =
installation quite painful.
Performance used to be tolerable but it seems to have gotten =
significantly worse in newer BIOS versions.
For now we are putting passively cooled GT710s in them but it would be =
nice to fix it properly.
I note that Linux has a DRM driver for these =
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/dr=
ivers/gpu/drm/ast=20
However I'm not sure how that integrates with X.. If Linux doesn't =
actually use the Xorg driver then I suppose that would explain why it's =
rotted and useless.
If that is the case, does anyone know difficult it would be to port the =
Linux DRM driver?
I did try contacting ASPEED and Supermicro but they pointed the finger =
at each other and then blamed FreeBSD so I'm a bit stuck.
Thanks.
