fonts corruption with 3dfx drm module
I've seen a much more serious problem which seems to be related to this:
I have AMD Athlon K7 650MHz, Via chipset, Voodoo5 5500AGP, MTTR enabled. What is happening here is that when switching back from init 5 to init 3 for instance, the system hangs completely and a blinking character appears in a black screen. There's no other way other than to power cycle the system. It seems to be a kernel panic.
Kernel version is 2.4.18, and it happens with or without DRM support, with and without FB support. There's no way I can have this version of the kernel to work here.
Thanks,
Christian Burger

Do you guys have
CONFIG_MTRRand/orCONFIG_FB_VESAenabled? Also which motherboard chipset?
MTRR, of course (do you like 2D and even 3D hardware accelerated without MTRR?), FB, no, chipset is a AMD 750 (Irongate C4), using X 4.1.99.1 DRI CVS.
I am with the DRI devel team and saw it occasionally with XFree86 DRI CVS trunk and the latest mesa-4-0-branch. At that time I had FB enabled as I remember right.
The current DRI stuff is "only" missing the latest XFree86 4.2.0 release 2D code. Update is under way.
I can _NOT_ see it without FB and currently running 2.4.18-pre7-J6-VM-23-preempt-lock.
/home/nuetzel> cat /proc/mtrr
reg00: base=0x00000000 ( 0MB), size= 512MB: write-back, count=1
reg01: base=0x20000000 ( 512MB), size= 128MB: write-back, count=1
reg02: base=0xec103000 (3777MB), size= 4KB: write-combining, count=1

Same problem here, with AMD K6 and Voodoo3 2000 PCI. All kernels and all XFree86 4.x.x versions. Although it doesn't hang the machine. Usually just fonts in vc1 are messed up.
So, it's not MTRR nor AGP problem. It must be something in XFree86 tdfx driver. Accelerated-X doesn't show this problem.

I've seen a blinking character (green, if i can remember) with my voodoo 3 3000 PCI, but I could change the VT.
The only issue with my graphics card is the corruption of some characters, when switching X to/from vt. The most affected character is: ! .

Does anyone know how to trace this problem to check if it's related to tdfx? I think there are two modules for tdfx, one created for the DRI tree of X and one created from the kernel.
I don't know which we are supposed to use.
Besides this, I believe glide3.so.xxx library interacts with this part of the code, so it might also be a reason for the problem.
Anyone knows how to investigate this further? Does this make any sense? Thanks,
Christian Burger
