2015-06-27Pick up where i left off in april:Frans Kaashoek7-45/+47
- move log into metadata part of disk, so that marking that the log's blocks are in use falls out for free - superblock describes the whole disk (sizes and offets) - sizes and offsets are computed in one place (mkfs) and the rest of the code refers to the superblock for these values, instead of recomputing them.
2015-04-10One ide command for nsector_per_block generates nsector_per_block interrupts,Frans Kaashoek1-1/+1
instead of 1. ideintr() should wait for nsector_per_block interrupts before waking up the reader; now it wakes up the reader after 1 interrupt, which apparently means that the first sector is available of the command instead of all. For now keep BSIZE to 512.

2015-04-03Disentangle block size from the disk's sector size. Set block size to 1024 ↵Frans Kaashoek11-86/+91
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.
2015-03-24Fix missing NUL-terminator in grepAustin Clements1-1/+2
Currently, grep read()s into a buffer and then uses the buffer as a string. Since there's no NUL-terminator, this can cause it to falsely identify line breaks and matches from leftover data on earlier lines and, if a line fills up the entire buffer, to read past the end of the buffer. Fix this by NUL-terminating any data returned by read(). Thanks to Keiichi Watanabe for the report.

2014-10-03Increase VM memory when running qemu-memfsAustin Clements1-1/+1
Presumably because of the pre-loaded file system, the default RAM is insufficient when running kernelmemfs
2014-10-03Make kernelmemfs depend on kernel.ldAustin Clements1-1/+1
2014-10-03Fix kernelmemfs linkingAustin Clements1-1/+1
Commit 9aa0337d introduced a linker script for linking the kernel image, but only changed the kernel target to use it. kernelmemfs was still using the old linker command line arguments, which weren't sufficient.

2014-09-12whoops. forgot date.hCody Cutler1-0/+8
2014-09-12cmosgetdate() for system-call homeworkCody Cutler4-3/+72
the day of reckoning has come for the debug port "Shutdown" hack. instead of mucking with ACPI or using a new hack, the student will now write sys_date() using the cmosgetdate() helper.

2012-08-24Various fixes and improvements to printpcsAustin Clements1-8/+11
Search for an addr2line that supports elf32-i386. Don't print the path of addr2line as a side-effect of which. Don't uselessly pipe "grep '^ '" to addr2line's stdin. Enable as many pretty-printing and otherwise helpful options as possible (this makes the output *much* more pleasant on modern addr2lines).
