TheOddGarlic c6f7f7665c IDE: Implement writing using Bus Mastering DMA 2022-08-17 17:19:27 +03:00
TheOddGarlic 9329059510 IDE: Add LBA28 addressing support 
LBA28 is obsolete at this point, but we prefer to use it over LBA48
whenever we can because LBA28 is faster.

TheOddGarlic 8a1c77db58 IDE: Rename PiixIde to PciIde, use it for all IDE controllers 
If the controller is not a known PCI IDE controller, then we warn about
the controller during PCI device discovery. :^)

TheOddGarlic 3836416891 PCI: add PIIX3_IDE to supported devices 
PIIX4_IDE and PIIX3_IDE are similar enough that we can have one driver
for both.

TheOddGarlic 91c1783b99 vfs+ext2: initial FsNode::read() implementation 
The VFS side of things for read() should be done, however due to my
limited ext2 knowledge, I've not implemented partially reading a file,
and in this state only full files can be read.

TheOddGarlic 600a81adf7 vfs: FsNode::release() implementation and weak ref to VFS node in file descriptors 2022-08-08 08:21:35 +03:00
TheOddGarlic 2a163a55ee vfs: rename FsNode::close() to FsNode::release() 
FsNode::close() will instead become a method that takes a closes a file descriptor, while release() will close the whole VFS node.

Erin cd8e6e4b3b So I have two news for you. One good and one bad. 
We have async, but we got rid of the preëmptive sched... wait, that's two good news, anyways, have a nice day.
