Bug #: 46006 Summary: [r300g, bisected] piglit glsl-max-varyings fails Classification: Unclassified Product: Mesa Version: git Platform: Other OS/Version: All Status: NEW Keywords: regression Severity: normal Priority: medium Component: Drivers/Gallium/r300 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: pavel.ondracka@email.cz CC: maraeo@gmail.com

This is the last r300g piglit regression from 7.11 to 8.0. I'm not sure if this is a valid bug, there is lots of errors:

r300: ERROR: FS input generic 20 unassigned, not enough hardware slots (it's not a bug, do not report it). r300: ERROR: FS input generic 21 unassigned, not enough hardware slots (it's not a bug, do not report it).

However since this is a regression I'm reporting it nevertheless. May also be related to bug 34201

Output: Vertical axis: Increasing numbers of varyings. Horizontal axis: Which of the varyings contains the color. GL_MAX_VARYING_FLOATS = 40 Probe at (8,98) Expected: 0.000000 1.000000 0.000000 Observed: 0.000000 0.000000 0.000000 Failure with 9 vec4 varyings used in varying index 0 Probe at (8,110) Expected: 0.000000 1.000000 0.000000 Observed: 0.000000 0.000000 0.000000 Failure with 10 vec4 varyings used in varying index 0

1ded658ce074a85bc08c989ff17840b840ff3051 is the first bad commit commit 1ded658ce074a85bc08c989ff17840b840ff3051 Author: Marek Olšák maraeo@gmail.com Date: Tue Nov 22 15:05:29 2011 +0100

st/mesa: add color varyings to MaxVarying

The linker now adds color varyings to the number of used varyings and checks against that limit.

NOTE: This is a candidate for the 7.11 branch.
