 1ASM sources for auto generated shaders
 2======================================
 3
 4The i915/gt/hsw_clear_kernel.c and i915/gt/ivb_clear_kernel.c files contain
 5pre-compiled batch chunks that will clear any residual render cache during
 6context switch.
 7
 8They are generated from their respective platform ASM files present on
 9i915/gt/shaders/clear_kernel directory.
10
11The generated .c files should never be modified directly. Instead, any modification
12needs to be done on the on their respective ASM files and build instructions below
13needs to be followed.

18Environment
19-----------
20
21IGT GPU tool scripts and the Mesa's i965 instruction assembler tool are used
22on building.
23
24Please make sure your Mesa tool is compiled with "-Dtools=intel" and
25"-Ddri-drivers=i965", and run this script from IGT source root directory"
26
27The instructions below assume:
28    *  IGT gpu tools source code is located on your home directory (~) as ~/igt
29    *  Mesa source code is located on your home directory (~) as ~/mesa
30       and built under the ~/mesa/build directory
31    *  Linux kernel source code is under your home directory (~) as ~/linux
