Requirements
|
||
|
|
^^^^^^^^^^^^
|
||
|
|
|
||
|
|
* An x86 processor with AVX or AVX2
|
||
|
|
* LLVM version 3.6 or later
|
||
|
|
|
||
|
|
Building
|
||
|
|
^^^^^^^^
|
||
|
|
|
||
|
|
To build with GNU automake, select building the swr driver at
|
||
|
|
configure time, for example: ::
|
||
|
|
|
||
|
|
configure --with-gallium-drivers=swrast,swr
|
||
|
|
|
||
|
|
Using
|
||
|
|
^^^^^
|
||
|
|
|
||
|
|
On Linux, building will create a drop-in alternative for libGL.so into::
|
||
|
|
|
||
|
|
lib/gallium/libGL.so
|
||
|
|
|
||
|
|
or::
|
||
|
|
|
||
|
|
build/foo/gallium/targets/libgl-xlib/libGL.so
|
||
|
|
|
||
|
|
To use it set the LD_LIBRARY_PATH environment variable accordingly.
|
||
|
|
|
||
|
|
**IMPORTANT:** Mesa will default to using llvmpipe or softpipe as the default software renderer. To select the OpenSWR driver, set the GALLIUM_DRIVER environment variable appropriately: ::
|
||
|
|
|
||
|
|
GALLIUM_DRIVER=swr
|
||
|
|
|
||
|
|
To verify OpenSWR is being used, check to see if a message like the following is printed when the application is started: ::
|
||
|
|
|
||
|
|
SWR detected AVX2
|
||
|
