Summary: dEQP-GLES3.functional.fbo.completeness.renderable.rend
erbuffer.color0 tests fail due to enabling of GL_RGB
and GL_RGBA
Product: Mesa
Version: git
Hardware: All

The following dEQP tests fail due to a recent commit that enables GL_RGB and
GL_RGBA internal formats for render buffers:
dEQP-GLES3.functional.fbo.completeness.renderable.renderbuffer.color0.rgb_unsigned_byte

mesa: Enables GL_RGB and GL_RGBA unsized internal formats for OpenGL ES 3.0
GL_RGB and GL_RGBA are valid internal formats on a GLES3 profile. See
"Table 1. Unsized Internal Formats" at
https://www.khronos.org/opengles/sdk/docs/man3/html/glTexImage2D.xhtml.
Fixes 2 dEQP tests:
- dEQP-GLES3.functional.state_query.internal_format.rgb_samples
- dEQP-GLES3.functional.state_query.internal_format.rgba_samples
Reviewed-by: Brian Paul <bri...@vmware.com>
This commit fixes tests where glGetInternalformativ() is used to get the number
of samples supported by a particular internal format for a render buffer. Pg
242 of the GLES 3.0.4 spec implies that GL_RGB and GL_RGBA are valid inputs to
glGetInternalformativ(). However, these are unsized internal formats and are
not supported for render buffers according to pg 204 of the spec, which states
a renderbuffer's internal format "must be a sized internal format...".
The commit updates _mesa_base_fbo_format() to allow GL_RGB and GL_RGBA as valid
render buffer internal formats. It has the effect of enabling those formats
for glGetInternalformativ() and
glRenderBufferStorage()/glRenderBufferStorageMultisample(). It should have
only enabled the formats for glGetInternalformativ().
Steps to reproduce:
# ./deqp-gles3
--deqp-case=dEQP-GLES3.functional.fbo.completeness.renderable.renderbuffer.color0.rgb_unsigned_byte
