I think the Summary is misleading, it should be obvious tdfx_dri requires
libglide-v3 and this dependency should be supported by distribution. X shouldn't
obviously crash with SEGV, but that's another matter. Instead, the summary
should be about a hang in tdfx, not only Banshee is affected.
Today I did an upgrade to Xorg 7.1. I use not Banshee, but Voodoo3. As we can
see in pasted Xorg logs, AIGLX initializes drm, but somehow locks it in a hard
way. libdrm's drmGetLock stucks in DRM_IOCTL_LOCK ioctl call (not really looping
with the while there, the ioctl gets stuck and never returns), a bt from
glxinfo:
#0 0x420ca402 in __kernel_vsyscall ()
#1 0x429c54b9 in ?? () from /lib/libc.so.6
#2 0x00166004 in drmGetLock (fd=4, context=2, flags=0) at xf86drm.c:1231
#3 0x001cd0f4 in tdfxMakeCurrent (driContextPriv=0x8a99040,
driDrawPriv=0x8d2ec20, driReadPriv=0x8d2ec20) at tdfx_context.c:488
(rest shouldn't be relevant, besides I built Mesa with -O2 again after
yesterdays debugging)
This is FC5 with aiglx repository:
libdrm-2.0.2-2.fc5.aiglx
mesa-libGL-6.5-19.fc5.aiglx.l0 ("l0" is my patch for bug #7574)
xorg-x11-server-Xorg-1.1.1-17.fc5.aiglx
kernel-2.6.17-1.2174_FC5 (dmesg says: [drm] Initialized drm 1.0.1 20051102 and
[drm] Initialized tdfx 1.0.0 20010216 on minor 0)
tdfx driver is 1.1.1, but I see people use 1.2.1 and see the same behavior.
The very nasty effect of this hang is that enabling metacity's compositing hangs
whole X (I guess the AIGLX-enabled server locks on the same ioctl, but haven't
tried to debug it).
