Summary: radeon-rewrite r200: Error messages during rendering
Product: DRI
Version: DRI CVS
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: DRM/Radeon
AssignedTo: [email protected]
ReportedBy: [email protected]
Since commit f616995e5ed56745c4470b2ca5aeeb8d89a8c9db, the r200 driver writes
lots of error messages during rendering. This is reproducible with glxgears:
ste...@laptop ~/src/mesa/src/mesa/drivers/dri/r200 $ glxgears
CS section size missmatch start at (r200_state_init.c,ctx_emit_cs,510) 22 vs 26
CS section end at (r200_state_init.c,ctx_emit_cs,543)
CS section size missmatch start at (r200_state_init.c,ctx_emit_cs,510) 22 vs 26
CS section end at (r200_state_init.c,ctx_emit_cs,543)
CS section size missmatch start at (r200_state_init.c,ctx_emit_cs,510) 22 vs 26
CS section end at (r200_state_init.c,ctx_emit_cs,543)
etc, etc, etc
There are no visible rendering bugs in glxgears, but in other apps many vertex
program and ATI_fragment_programs do not work correctly(The commit above made
the extensions show up as expected). Do these messages indicate that something
deeper is wrong, or are they just spam? The failing shaders include the
DolphinVS.exe dx8 sdk sample when run with Wine, the Bumpmap samples and vertex
blend sample. I think the directx8 sdk is not publically available any more,
but I can try to write stand alone test apps to show these bugs if needed.
(Wine uses GL_ATI_fragment_shader on r200 cards for fixed function fragment
processing)
The error messages do not show up in mesa master, and the extensions work
correctly.
