From 4f430e9ab56443e822171b7881f4d50475dbaf25 Mon Sep 17 00:00:00 2001 From: Korey Sewell Date: Mon, 10 Apr 2006 12:23:17 -0400 Subject: Finally MIPS does hello world! arch/mips/isa/bitfields.isa: add RS_SRL bitfield ...these must be set to 0 for a SRL instruction arch/mips/isa/decoder.isa: Make unimplemented instructions Fail instead of just Warn Edits to SRA & SRAV instructions Implement CFC1 instructions Unaligned Memory Access Support (Maybe Not fully functional yet) Enforce a more strict decode policy (in terms of different bitfields set to 0 on certain instructions) arch/mips/isa/formats/branch.isa: Fix disassembly arch/mips/isa/formats/int.isa: Add sign extend Immediate and zero extend Immediate to Int class. Probably a bit unnecessary in the long run since these manipulations could be done in the actually instruction instead of keep a int value arch/mips/isa/formats/mem.isa: Comment/Remove out split-memory access code... revisit this after SimpleCPU works arch/mips/isa/formats/unimp.isa: Add inst2string function to Unimplemented panic. PRints out the instruction binary to help in debuggin arch/mips/isa/formats/unknown.isa: define inst2string function , use in unknown disassembly and panic function arch/mips/isa/operands.isa: Make "Mem" default to a unsigned word since this is MIPS32 arch/mips/isa_traits.hh: change return values to 32 instead of 64 arch/mips/linux_process.cc: assign some syscalls to the right functions cpu/static_inst.hh: more debug functions for MIPS (these will be move to the mips directory soon) mem/page_table.cc: mem/page_table.hh: toward a better implementation for unaligned memory access mem/request.hh: NO ALIGN FAULT flag added to support unaligned memory access sim/syscall_emul.cc: additional SyscallVerbose comments --HG-- extra : convert_revision : 1987d80c9f4ede507f1f0148435e0bee97d2428c --- mem/request.hh | 2 ++ 1 file changed, 2 insertions(+) (limited to 'mem/request.hh') diff --git a/mem/request.hh b/mem/request.hh index 5e2275741..4b4703a0b 100644 --- a/mem/request.hh +++ b/mem/request.hh @@ -58,6 +58,8 @@ const unsigned NO_FAULT = 0x020; const unsigned PF_EXCLUSIVE = 0x100; /** The request should be marked as LRU. */ const unsigned EVICT_NEXT = 0x200; +/** The request should ignore unaligned access faults */ +const unsigned NO_ALIGN_FAULT = 0x400; class Request { -- cgit v1.2.3
