Hello! below some status-update about my radeon7500 ... (sadly no good news)

Felix,Unfortunately even that didnt make "my" lockups with xmms
I've committed the first version for now, because
1) it's cleaner
2) it emits at most 1 wait per statechange
3) I'm not convinced that there are many statechanges that don't touch any of tcl, tex0 or tex1 -- ie I think the second version would emit a wait on *almost* every statechange.
If you want to narrow the lockup conditions down further, feel free & I'll commit the results.

and two OpenGL-Visualisation-Plugins go away.
(LAVA and OpenGL Spectrum Analyzer)
I think any multi-threaded OpenGL-app should trigger "my"
bug if it draws enough (more than a cube).
disabling VTXFMT helps: no lockups anymore, everything works fine,
but I have to disable SSE, too,
otherwise I would get a sigfpe on my athlonXP1700+
I tried it out on another system with BX440 chipset and Celeron466,
kernel 2.4.18, suse 7.2: same result: hangs, freezes, application-crashs.
(that was without that last patch)
Another discovery:
On the celeron I had manually set MESA_NO_SSE=1, otherwise
quake3 would get a signal 8 (I think) and die.
I thought mesa checks itself if SSE is available?
And I tried quake3 with my voodoo3: there I saw the player-model
on the right side in the model-choose-menu.
I dont see it with my radeon7500.
And here are two demos (unfortunately there are not so much
demos for linux available, so I tried some win-demos with wine...)
which have rendering errors when using with / without TCL !
#====================================================
Configuration:
Radeon7500, Athlon XP 1700+,
wine-cvs-20021123,
DRI-CVS-mesa-4-1-branch-20021123,
OpenGL renderer string: Mesa DRI Radeon 20021009 AGP 2x x86/MMX/3DNow!/SSE TCL
OpenGL version string: 1.2 Mesa 5.0
colordepth: 24bpp
#====================================================
rgba_coming.zip: (64k-demo)
ftp://ftp.scene.org/pub/parties/2002/bcnparty10/in64/
wine: perfect: no fixmes/warnings/errors
DRI: default: if these quads are intendet: perfect
... someone should try it out on a different system
RADEON_TCL_FORCE_DISABLE=1: rendering errors: missing triangles/quads/strips
RADEON_NO_VTXFMT=1: like default
#----------------------------------------------------
petroleo_boah.zip: (demo, 5,9M)
ftp://ftp.scene.org/pub/parties/2002/bcnparty10/demo/
wine: good: some fixmes:system:ChangeDisplaySettingsA
:dsound...
DRI: default: rendering errors: artifacts, texturing errors
RADEON_TCL_FORCE_DISABLE=1: looks perfect
RADEON_NO_VTXFMT=1: looks perfect
RADEON_NO_CODEGEN=1: like default
#----------------------------------------------------
best regards,
Andreas
