hello.
I have been experiencing difficulties trying to get fixed-pipeline TCL
and ARBVP1 hardware support for an ATI 9250 PCI board (chip id 0x5960)
under Xorg 1.5.3 and FOSS ATI DRI edge 6.10, running on a ppc station.
Is there such a know issue or does my problem present an isolated
case?
for the record, glxinfo -i reports nothing wrong on the subject:
$ glxinfo -l
<snip>
OpenGL vendor string: Tungsten Graphics, Inc.
OpenGL renderer string: Mesa DRI R200 20060602 TCL
OpenGL version string: 1.3 Mesa 7.2
<snip>
OpenGL limits:

GL_MAX_ELEMENTS_VERTICES = 3000
GL_MAX_ELEMENTS_INDICES = 3000
<snip>
GL_VERTEX_PROGRAM_ARB:
GL_MAX_PROGRAM_INSTRUCTIONS_ARB = 128
GL_MAX_PROGRAM_NATIVE_INSTRUCTIONS_ARB = 128
GL_MAX_PROGRAM_TEMPORARIES_ARB = 128
GL_MAX_PROGRAM_NATIVE_TEMPORARIES_ARB = 12
GL_MAX_PROGRAM_PARAMETERS_ARB = 128
GL_MAX_PROGRAM_NATIVE_PARAMETERS_ARB = 192
GL_MAX_PROGRAM_ATTRIBS_ARB = 16
GL_MAX_PROGRAM_NATIVE_ATTRIBS_ARB = 12
GL_MAX_PROGRAM_ADDRESS_REGISTERS_ARB = 1
GL_MAX_PROGRAM_NATIVE_ADDRESS_REGISTERS_ARB = 1
GL_MAX_PROGRAM_LOCAL_PARAMETERS_ARB = 128
GL_MAX_PROGRAM_ENV_PARAMETERS_ARB = 128
GL_MAX_PROGRAM_ALU_INSTRUCTIONS_ARB = 128
GL_MAX_PROGRAM_TEX_INSTRUCTIONS_ARB = 128
GL_MAX_PROGRAM_TEX_INDIRECTIONS_ARB = 128
GL_MAX_PROGRAM_NATIVE_ALU_INSTRUCTIONS_ARB = 128
GL_MAX_PROGRAM_NATIVE_TEX_INSTRUCTIONS_ARB = 128
GL_MAX_PROGRAM_NATIVE_TEX_INDIRECTIONS_ARB = 128
but the exhibited performance degradation of more than a decimal order
of magnitude compared to the same test case on a quite similar hw
configuration, just under osx, suggests software emulation.
here's the complete components version info as seen in Xorg.0.log:
$ grep -A 6 -e "LoadModule: \"dri\"" -e "LoadModule: \"ati\"" -e
"LoadModule: \"radeon\"" /var/log/Xorg.0.log
