ASM sources for auto generated shaders
|
||
|
|
======================================
|
||
|
|
|
||
|
|
The i915/gt/hsw_clear_kernel.c and i915/gt/ivb_clear_kernel.c files contain
|
||
|
|
pre-compiled batch chunks that will clear any residual render cache during
|
||
|
|
context switch.
|
||
|
|
|
||
|
|
They are generated from their respective platform ASM files present on
|
||
|
|
i915/gt/shaders/clear_kernel directory.
|
||
|
|
|
||
|
|
The generated .c files should never be modified directly. Instead, any modification
|
||
|
|
needs to be done on the on their respective ASM files and build instructions below
|
||
|
|
needes to be followed.

|
Building
|
||
|
|
========
|
||
|
|
|
||
|
|
Environment
|
||
|
|
-----------
|
||
|
|
|
||
|
|
IGT GPU tool scripts and the Mesa's i965 instruction assembler tool are used
|
||
|
|
on building.
|
||
|
|
|
||
|
|
Please make sure your Mesa tool is compiled with "-Dtools=intel" and
|
||
|
|
"-Ddri-drivers=i965", and run this script from IGT source root directory"
|
||
|
|
|
||
|
|
The instructions bellow assume:
|
||
|
|
* IGT gpu tools source code is located on your home directory (~) as ~/igt
|
||
|
|
* Mesa source code is located on your home directory (~) as ~/mesa
|
||
|
|
and built under the ~/mesa/build directory
|
||
|
|
* Linux kernel source code is under your home directory (~) as ~/linux
|
||
|
|
|
||
|
|
