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

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 :^)

3cba2a8a78 Kernel: Add a beep() syscall that beeps the PC speaker.
Hook this up in Terminal so that the '\a' character generates a beep.
Finally emit an '\a' character in the shell line editing code when
backspacing at the start of the line.

8cbb7f101f Kernel: Have File virtuals take a FileDescriptor& rather than a Process&.
This will allow us to implement different behaviors depending on the role
of the descriptor a File is being accessed through.

f042b3adeb Kernel: Make the right shift key work.
I never realized the right shift key wasn't hooked up since my left pinky
always hovers over the left shift key, ready to rock.

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. :^)

2d7cad6a16 Kernel: Make sure we don't use any FPU/MMX/SSE instructions. 2019-04-22 23:38:33 +02:00

3817f5f619 Kernel+LibC: Add a DebugLogDevice that forwards everything to I/O port 0xe9.
This is then used to implement the userspace dbgprintf() in a far more
efficient way than what we had before. :^)
