Summary: glBlendFuncSeparatei (IrisPro with Mesa DRI / 3.0 Mesa
10.0.1)
QA Contact: intel-3d-bugs at lists.freedesktop.org
Severity: normal
Classification: Unclassified

Hardware: x86-64 (AMD64)
Status: NEW
Version: 10.0
Component: Drivers/DRI/i965

Mesa reports availability of ARB_draw_buffers_blend but glBlendFuncSeparatei
fails with GL_INVALID_OPERATION.
HW is BrixPro with i7-4770R with SteamOS (Mesa DRI / 3.0 Mesa 10.0.1).
To reproduce bug:
git clone git://github.com/bkaradzic/bx.git
git clone git://github.com/bkaradzic/bgfx.git
cd bgfx
../bx/tools/linux/bin/premake4 --file=premake/premake4.lua --gcc=linux-gcc
gmake
make -C .build/projects/gmake-linux config=debug64 example-19-oit
cd examples/runtime
../../.build/linux64_gcc/bin/example-18-oitDebug
Switch to MRT option, and you will get (MESA_DEBUG=verbose):
"Mesa: User error: GL_INVALID_OPERATION in unsupported function called
(unsupported extension or deprecated function?)"
