2006-12-12Fix bugs in tlbmap (and thus rangemap since the code is nearly identical)Ali Saidi
Deal with block initializing stores (by doing nothing, at some point we might want to do the write hint 64 like thing) Fix tcc instruction igoner in legion-lock stuff to be correct in all cases Have console interrupts warn rather than panicing until we figure out what to do with interrupts src/arch/sparc/miscregfile.cc: src/arch/sparc/miscregfile.hh: add a magic miscreg which reads all the bits the tlb needs in one go src/arch/sparc/tlb.cc: initialized the context type and id to reasonable values and handle block init stores src/arch/sparc/tlb_map.hh: fix bug in tlb map code src/base/range_map.hh: fix bug in rangemap code and add range_multimap (these are probably useful for bus range stuff) src/cpu/exetrace.cc: fixup tcc ignore code to be correct src/dev/sparc/t1000.cc: make console interrupt stuff warn instead of panicing until we get interrupt stuff figured out src/unittest/rangemaptest.cc: fix up the rangemap unit test to catch the missing case --HG-- extra : convert_revision : 70604a8b5d0553aa0b0bd7649f775a0cfa8267a5

2006-12-06Many more fixes for SPARC_FS. Gets us to the point where SOFTINT startsAli Saidi

2006-12-04More changes to get SPARC fs closer. Now at 1.2M cycles before differenceAli Saidi
configs/common/FSConfig.py: seperate the hypervisor memory and the guest0 memory. In reality we're going to need a better way to do this at some point. Perhaps auto generating the hv-desc image based on the specified config. src/arch/sparc/isa/decoder.isa: change reads/writes to the [hs]tick(cmpr) registers to use readmiscregwitheffect src/arch/sparc/miscregfile.cc: For niagra stick and tick are aliased to one value (if we end up doing mps we might not want this). Use instruction count from cpu rather than cycles because that is what legion does we can change it back after were done with legion src/base/bitfield.hh: add a new function mbits() that just masks off bits of interest but doesn't shift src/cpu/base.cc: src/cpu/base.hh: add instruction count to cpu src/cpu/exetrace.cc: src/cpu/m5legion_interface.h: compare instruction count between legion and m5 too src/cpu/simple/atomic.cc: change asserts of packet success to if panics wrapped with NDEBUG defines so we can get some more useful information when we have a bad address src/dev/isa_fake.cc: src/dev/isa_fake.hh: src/python/m5/objects/Device.py: expand isa fake a bit more having data for each size request, the ability to have writes update the data and to warn on accesses src/python/m5/objects/System.py: convert some tabs to spaces src/python/m5/objects/T1000.py: add more fake devices for each l1 bank and each memory controller --HG-- extra : convert_revision : 8024ae07b765a04ff6f600e5875b55d8a7d3d276
