Add ability to load the ROM bin files, cleanup lockstep printing a bit Since we don't have a platform yet, you need to comment out the default responder stuff in Bus.py to make it work. SConstruct: Add TARGET_ISA to the list of environment variables that end up in the build_env for python configs/common/FSConfig.py: add a simple SPARC system to being testing with, you'll need to change makeLinuxAlphaSystem to makeSparcSystem in fs.py for now src/SConscript: add a raw file object, at least until we get more info about how to compile openboot properly src/arch/sparc/system.cc: src/arch/sparc/system.hh: add parameters for ROM files (OBP/Reset/Hypervisor), a ROM, load files into ROM src/base/loader/object_file.cc: src/base/loader/object_file.hh: add option to try raw when nothing works src/cpu/exetrace.cc: cleanup lockstep printing a little bit src/cpu/m5legion_interface.h: change the instruction to be 32 bits because it is src/mem/physical.cc: fix assert that doesn't work if memory starts somewhere above 0 src/python/m5/objects/BaseCPU.py: Add if statement to choose between sparc tlbs and alpha tlbs src/python/m5/objects/System.py: Add a sparc system that sets the rom addresses correctly src/python/m5/params.py: add the ability to add Addr() together --HG-- extra : convert_revision : bbbd8a56134f2dda2728091f740e2f7119b0c4af --- src/cpu/m5legion_interface.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'src/cpu/m5legion_interface.h') diff --git a/src/cpu/m5legion_interface.h b/src/cpu/m5legion_interface.h index 0fa0e7279..9338d9ca0 100644 --- a/src/cpu/m5legion_interface.h +++ b/src/cpu/m5legion_interface.h @@ -30,7 +30,7 @@ #include -#define VERSION 0xA1000001 +#define VERSION 0xA1000002 #define OWN_M5 0x000000AA #define OWN_LEGION 0x00000055 @@ -41,7 +41,7 @@ typedef struct { uint32_t version; uint64_t pc; - uint64_t instruction; + uint32_t instruction; uint64_t intregs[32]; } SharedData; -- cgit v1.2.3
