This directory is for shaders used in media_fill, gpgpu_fill, rendercopy
|
||
|
|
and media_spin libraries.
|
||
|
|
|
||
|
|
Till Gen8 shaders were generated using intel-gen4asm script (implementation in
|
||
|
|
assembler/ directory). From Gen8 it is possible to use Intel Graphics Assembler
|
||
|
|
to generate binary from asm instructions.

1. Clone IGC project
|
||
|
|
2. Go to igc/visa/iga
|
||
|
|
3. Build iga
|
||
|
|
cmake . && make
|
||
|
|
|
||
|
|
For maintaining compatibility with our tests there is a bin to hex converter
|
||
|
|
written in python:
|
||
|
|
$>converter.py input_file > output_file
|
||
|
|
e.g.$>python converter.py gen9_iga_output > gen9_hex_array
|
||
|
|
|
||
|

Commands used to generate the shader on gen7
|
||
|
|
$> m4 gpgpu_fill.gxa > gpgpu_fill.gxm
|
||
|
|
$> intel-gen4asm -g 7 -o <output> gpgpu_fill.gxm
|
