2016-09-02APIC IDs may not be consecutive and start from zero, so we cannot really use itFrans Kaashoek6-18/+26
as a direct index into cpus. Record apicid in struct cpu and have cpunum() look for it. Replace cpu->id with cpunum() everywhere, and replace cpu->id with cpu->apicid. Thanks to Xi Wang.

2016-08-18Small change to support RWMUL and WRMUL. Now xv6 truly works with a block sizeFrans Kaashoek1-3/+7
that is a multiple of the sector size.

2015-11-15Remove console input.lockNathaniel Wesley Filardo1-10/+13
Use cons.lock for everything. This eliminates the possibility that two CPUS independently, simultaneously manipulate the CRTC in cgaputc.

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.
