18c2ecf20Sopenharmony_ciASM sources for auto generated shaders 28c2ecf20Sopenharmony_ci====================================== 38c2ecf20Sopenharmony_ci 48c2ecf20Sopenharmony_ciThe i915/gt/hsw_clear_kernel.c and i915/gt/ivb_clear_kernel.c files contain 58c2ecf20Sopenharmony_cipre-compiled batch chunks that will clear any residual render cache during 68c2ecf20Sopenharmony_cicontext switch. 78c2ecf20Sopenharmony_ci 88c2ecf20Sopenharmony_ciThey are generated from their respective platform ASM files present on 98c2ecf20Sopenharmony_cii915/gt/shaders/clear_kernel directory. 108c2ecf20Sopenharmony_ci 118c2ecf20Sopenharmony_ciThe generated .c files should never be modified directly. Instead, any modification 128c2ecf20Sopenharmony_cineeds to be done on the on their respective ASM files and build instructions below 138c2ecf20Sopenharmony_cineedes to be followed. 148c2ecf20Sopenharmony_ci 158c2ecf20Sopenharmony_ciBuilding 168c2ecf20Sopenharmony_ci======== 178c2ecf20Sopenharmony_ci 188c2ecf20Sopenharmony_ciEnvironment 198c2ecf20Sopenharmony_ci----------- 208c2ecf20Sopenharmony_ci 218c2ecf20Sopenharmony_ciIGT GPU tool scripts and the Mesa's i965 instruction assembler tool are used 228c2ecf20Sopenharmony_cion building. 238c2ecf20Sopenharmony_ci 248c2ecf20Sopenharmony_ciPlease make sure your Mesa tool is compiled with "-Dtools=intel" and 258c2ecf20Sopenharmony_ci"-Ddri-drivers=i965", and run this script from IGT source root directory" 268c2ecf20Sopenharmony_ci 278c2ecf20Sopenharmony_ciThe instructions bellow assume: 288c2ecf20Sopenharmony_ci * IGT gpu tools source code is located on your home directory (~) as ~/igt 298c2ecf20Sopenharmony_ci * Mesa source code is located on your home directory (~) as ~/mesa 308c2ecf20Sopenharmony_ci and built under the ~/mesa/build directory 318c2ecf20Sopenharmony_ci * Linux kernel source code is under your home directory (~) as ~/linux 328c2ecf20Sopenharmony_ci 338c2ecf20Sopenharmony_ciInstructions 348c2ecf20Sopenharmony_ci------------ 358c2ecf20Sopenharmony_ci 368c2ecf20Sopenharmony_ci~ $ cp ~/linux/drivers/gpu/drm/i915/gt/shaders/clear_kernel/ivb.asm \ 378c2ecf20Sopenharmony_ci ~/igt/lib/i915/shaders/clear_kernel/ivb.asm 388c2ecf20Sopenharmony_ci~ $ cd ~/igt 398c2ecf20Sopenharmony_ciigt $ ./scripts/generate_clear_kernel.sh -g ivb \ 408c2ecf20Sopenharmony_ci -m ~/mesa/build/src/intel/tools/i965_asm 418c2ecf20Sopenharmony_ci 428c2ecf20Sopenharmony_ci~ $ cp ~/linux/drivers/gpu/drm/i915/gt/shaders/clear_kernel/hsw.asm \ 438c2ecf20Sopenharmony_ci ~/igt/lib/i915/shaders/clear_kernel/hsw.asm 448c2ecf20Sopenharmony_ci~ $ cd ~/igt 458c2ecf20Sopenharmony_ciigt $ ./scripts/generate_clear_kernel.sh -g hsw \ 468c2ecf20Sopenharmony_ci -m ~/mesa/build/src/intel/tools/i965_asm
