Remove I_BUSY, B_BUSY, and intrans defs and usages One spinlock per buf to avoid ugly loop in bget fix race in filewrite (don't update f->off after releasing lock)

2011-08-17Make elf proghdr fields match what objdump printsFrans Kaashoek3-7/+7
2011-08-16Switch back to #define for PHYSTOP. Using the E820 to retrieve the memory ↵Frans Kaashoek3-14/+8
map is too complicated (must be done in 16-bit real-mode, probably enlarged bootblock beyond 512 bytes, and a #define requires less explanation).
2011-08-16Clean up memlayout.hFrans Kaashoek6-28/+42
Get rid of last instances of linear address and "la" Get ready for detecting physical memory dynamically

2011-08-15Only commit log to disk if something was written in to it.Austin Clements1-5/+7
Without this, every write to the console results in log writes.

2011-08-15avoid deadlock by calling begin_trans() before locking any inodesRobert Morris5-15/+66
2011-08-15Separate more clearly bootloader from xv6 by renaming multiboot.S to entry.S ↵Frans Kaashoek4-22/+22
etc. Maybe the string boot shouldn't appear in xv6 code?

2011-08-09Use static page table for boot, mapping first 4Mbyte; no more segment trickFrans Kaashoek9-103/+1101
Allocate proper kernel page table immediately in main using boot allocator Remove pginit Simplify address space layout a tiny bit More to come (e.g., superpages to simplify static table)
2011-08-09Use kernel virtual addresses for BIOS memory, etc.Frans Kaashoek1-8/+8
2011-08-09Allow gas to use / as divide (instead of comment)Frans Kaashoek1-1/+1
Maybe not necessary, but don't want to waste time figuring this out again
2011-08-08One definition of several macros and constantsFrans Kaashoek7-33/+25
2011-08-08Speedup sbrk tst a bit (forking 100Mbyte processes is slow)Frans Kaashoek1-4/+10

All tests pass

2011-07-31Don't map IO space in the user part of the address spaceFrans Kaashoek2-10/+11
Passes all tests now (but need to update usertests to allow for more than 640k)
2011-07-29Map kernel highFrans Kaashoek20-70/+207
Very important to give qemu memory through PHYSTOP :(

2011-07-27Dirt simple loggingFrans Kaashoek11-47/+244
Passes usertests and stressfs Seems to recover correctly in a number of simple cases
2011-06-24Add -fno-omit-frame-pointer to compile flags.Austin Clements1-1/+1
At some point between gcc 4.4 and 4.6, omitting the frame pointer became default if any -O is specified. getcallerpcs relies on the frame pointer, so bring it back.
