Andreas Kling ab43658c55 Kernel: Move devices into Kernel/Devices/. 2019-04-03 12:36:40 +02:00
Andreas Kling 799177feda Kernel: Make BochsVGADevice a BlockDevice and support mmapping it. 
Currently you can only mmap the entire framebuffer.
Using this when starting up the WindowServer gets us yet another step
closer towards it moving into userspace. :^)

..to prepare for adding a BlockDevice class.

Andreas Kling 34e745b0b4 Add uid and gid to CharacterDevices. 
The vast majority of them will be owned by 0:0 (the default.)
However, PTY pairs will now be owned by the uid:gid of the opening process.

Andreas Kling b4e478aa50 Deallocate PTY's when they close. 
This required a fair bit of plumbing. The CharacterDevice::close() virtual
will now be closed by ~FileDescriptor(), allowing device implementations to
do custom cleanup at that point.

One big problem remains: if the master PTY is closed before the slave PTY,
we go into crashy land.
