Nathan Binkert fff9c93568 scons: make default target work again 2009-04-21 10:49:06 -07:00
Steve Reinhardt 7b2f8e6857 Set up m5threads tests on classic (non-ruby) memory system.
Just one test (40.m5threads-test-atomic) is set up for now.
These tests require that the m5threads SPARC binaries are present
in /dist or in test-progs.

Steve Reinhardt 03b3925e58 syscall_emul: style fixes (mostly wrapping overly long lines) 2009-04-21 08:17:36 -07:00
Steve Reinhardt 52b6764f31 syscall: Resolve conflicts between m5threads and Gabe's recent SE changes. 2009-04-21 08:17:36 -07:00
Daniel Sanchez b0e9654f86 Commit m5threads package.
This patch adds limited multithreading support in syscall-emulation
mode, by using the clone system call.  The clone system call works
for Alpha, SPARC and x86, and multithreaded applications run
correctly in Alpha and SPARC.

Steve Reinhardt 3083268d60 request: rename INST_READ to INST_FETCH. 2009-04-20 18:54:02 -07:00
Steve Reinhardt 7f8ea68a30 request: split public and private flags into separate fields.
This frees up needed space for more public flags.  Also:
- remove unused Request accessor methods
- make Packet use public Request accessors, so it need not be a friend

Gabe Black d90456a486 X86: Implement the stul microop.
This microop does a store and unlocks the requested address. The RISC86
microop ISA doesn't seem to have an equivalent to this, so I'm guessing that
the store following an ldstl is automatically unlocking. We don't do it this
way for performance reasons since the behavior is the same.

Gabe Black d2554ff030 X86: Implement the ldstl microop.
This microop does a load, checks that a store would succeed, and locks the
requested address.
