bb288c1baf IDEDiskDevice: Implement basic DMA writes.
This could share more code with reads, and generally be better. But it works
and it's considerably faster than PIO, so let's use it. :^)

ebf645d72a Kernel: Tidy up IDEDiskDevice a bit.
The main cleanup here is putting the I/O address base in a member variable.

5f26f83451 IDEDiskDevice: Add sysctl variable for turning DMA on/off. 2019-05-19 15:54:33 +02:00

c7d8aa6969 IDEDiskDevice: Support reading multiple sectors at a time with DMA.
This is another sizable improvement to GCC compile times.

ed79116e94 IDEDiskDevice: Use wait_for_irq() when waiting for DMA transfers.
Also make sure we return any device errors to caller.

c818773983 IDEDiskDevice: Add support for DMA reads.
I've only tested this with the PIIX3 chipset QEMU emulates, but it works
pretty well here. GCC compile times are cut roughly in half :^)

243e1d8462 Kernel: Use rep insw/outsw for IDE transfers.
There are much faster ways to do disk transfers, but I'm not implementing
those today. In the meantime, this is slightly nicer. :^)
