Bug ID: 107832
Summary: Gallium picking A16L16 formats when emulating
INTENSITY16 conflicts with mesa
Product: Mesa
Version: git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Mesa core
Assignee: [email protected]
Reporter: [email protected]
QA Contact: [email protected]
The piglit
ext_framebuffer_multisample-fast-clear GL_ARB_texture_float
fails with an assertion raised if the GL_INTENSITY16F texture format is
emulated by PIPE_FORMAT_L16A16_FLOAT that is actually picked by Gallium if no
relevant intensity format is available.
The problem is that in this case
glGetTexLevelParameteriv(..., GL_TEXTURE_INTENSITY_SIZE, ...)
will return a zero component size because the texture info us read from the
used replacement format that specifies that the intensity component size is 0,
and as a fallback only RG is expected.
