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 13needes to be followed. 14 15Building 16======== 17 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 bellow 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 32 33Instructions 34------------ 35 36~ $ cp ~/linux/drivers/gpu/drm/i915/gt/shaders/clear_kernel/ivb.asm \ 37 ~/igt/lib/i915/shaders/clear_kernel/ivb.asm 38~ $ cd ~/igt 39igt $ ./scripts/generate_clear_kernel.sh -g ivb \ 40 -m ~/mesa/build/src/intel/tools/i965_asm 41 42~ $ cp ~/linux/drivers/gpu/drm/i915/gt/shaders/clear_kernel/hsw.asm \ 43 ~/igt/lib/i915/shaders/clear_kernel/hsw.asm 44~ $ cd ~/igt 45igt $ ./scripts/generate_clear_kernel.sh -g hsw \ 46 -m ~/mesa/build/src/intel/tools/i965_asm
