xv6-riscv - MIT xv6-RISCV kernel modified to RV64I base integer extension

Age	Commit message (Collapse)	Author
2019-06-05	start at support for multiple CPUs	Robert Morris

2016-08-25	Remove trailing white space with:	Frans Kaashoek
	for f in .{h,c}; do sed -i .sed 's/[[:blank:]]$//' $f; done (Thanks to Nicolás Wolovick)
2015-04-03	Disentangle block size from the disk's sector size. Set block size to 1024 ↵	Frans Kaashoek
	to show that they can be different. Clean up mkfs, simplifying specifying fs parameters, remove some redundancy between fs and mkfs, and fix disk layout bugs. Call blocks in the file system blocks instead of sectors. Passes usertests for different block sizes.
2011-09-04	Make the ELF entry point a physical address	Austin Clements
	This way, the bootloader doesn't have to translate the entry point. This also makes xv6 multiboot-compliant and follows the convention used by Linux.
2011-08-31	move the kernel to 0x80000000	Robert Morris

2011-08-17	bootloader reads into a physical address (not a virtual address)	Frans Kaashoek

2011-08-17	Make elf proghdr fields match what objdump prints	Frans Kaashoek

2011-07-29	Map kernel high	Frans Kaashoek
	Very important to give qemu memory through PHYSTOP :(
2011-01-11	make new code like old code	Russ Cox
	Variable declarations at top of function, separate from initialization. Use == 0 instead of ! for checking pointers. Consistent spacing around {, *, casts. Declare 0-parameter functions as (void) not (). Integer valued functions return -1 on failure, 0 on success.
2010-09-15	Simplify boot loader by removing some JOS'isms	Austin Clements

2009-03-08	xv6: boot loader adjustments	rsc
	do Bochs breakpoint and spin in bootasm.S. not needed in bootmain too. fix readseg bug (rounding of va). zero segments when memsz > filesz. no need to clear BSS in kernel main. make bootother.S like bootasm.S
2007-09-15	fix comments	rtm

2007-08-22	PDF at http://am.lcs.mit.edu/~rsc/xv6.pdf	rsc
	Various changes made while offline. + bwrite sector argument is redundant; use b->sector. + reformatting of files for nicer PDF page breaks + distinguish between locked, unlocked inodes in type signatures + change FD_FILE to FD_INODE + move userinit (nee proc0init) to proc.c + move ROOTDEV to param.h + always parenthesize sizeof argument
