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. 
pdf has very good page breaks now.
would be a good copy for fall 2009.

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].

	disasm/25 "main0"
	vb 0x8:"main0"+0x5f
