fe4623b99c Fix for gdbstub argument change in qemu 0.11. Rename qemu-gdb-nox target to qemu-nox-gdb because you frequently want to add the gdb part, but rarely the nox part. 2010-08-30 12:22:08 -04:00

7e0cc8e36e another attempt at cpu-local variables. 
this time do it ourselves instead of piggybacking on TLS.
add -fno-pic to Makefile; pic code breaks our fake TLS.

0aef891495 shuffle and tweak for formatting.

19333efb9e Some proc cleanup, moving some of copyproc into allocproc. 
Also, an experiment: use "thread-local" storage for c and cp
instead of the #define macro for curproc[cpu()].

f32f3638f4 Various cleanup: 
- Got rid of dummy proc[0].  Now proc[0] is init.
 - Added initcode.S to exec /init, so that /init is
   just a regular binary.
 - Moved exec out of sysfile to exec.c
 - Moved code dealing with fs guts (like struct inode)
   from sysfile.c to fs.c.  Code dealing with system call
   arguments stays in sysfile.c
 - Refactored directory routines in fs.c; should be simpler.
 - Changed iget to return *unlocked* inode structure.
   This solves the lookup-then-use race in namei
   without introducing deadlocks.
   It also enabled getting rid of the dummy proc[0].

f70172129c run without lapic and ioapic, if they are not present 
if no lapic available, use 8253pit for clock
now xv6 runs both on qemu (uniprocessor) and bochs (uniprocessor and MP)
