Andreas Kling 8293a0ff36 Rework DiskDevice's read() and write() to be non-virtual wrappers. 
This way subclasses only have to implement readBlock() and writeBlock().
read() and write() require that the offset and length are both divisible
by the blockSize().

Andreas Kling 9cd0a34b5c BlockDevice -> DiskDevice. 
BlockDevice was the wrong name for this abstraction, since a block device
is a type of file in a unix system, and we should use that name for that
concept in the fs implementation.

Andreas Kling 72bb80a9ae These changes were lying around uncommitted in the old repo. 
I'm just gonna commit them without too much thinking and then take
it from there.

Andreas Kling 87d41bdca4 If an interrupt comes from the slave PIC, both PICs need an EOI. 2018-10-16 11:05:29 +02:00
Andreas Kling 9396108034 Import the "gerbert" kernel I worked on earlier this year. 
It's a lot crappier than I remembered it. It's gonna need a lot of work.

Andreas Kling 9528edab92 Move readEntireInode() up to FileSystem (from ext2.) 
It's just a wrapper around multiple calls to readInodeBytes() now.

even if that machine has its own ideas about foo_t types.
