8fa7d96f50 SharedGraphics: Import another 8x10 fixed-width font I made. 
It's not perfect yet but it's quite nice to look at so I'll make this the
system default for now. :^)

6cc1a9d90a sh: Support basic backspacing on the command line. 
It's weird that I didn't do this sooner. I don't know how many tims
I've had to retype a misspelled command. :^)

shell's working directory. :^)

8a3af99416 SharedGraphics: Optimize Painter::draw_bitmap(). 
Manually peel as much as possible out of the loop for a ~100% speedup.

267a903dd0 Terminal: Redraw entire line if any of its characters are dirty. 
This means we only have to do one fill_rect() per line and the whole process
ends up being ~10% faster than before.

Also added a read_tsc() syscall to give userspace access to the TSC.

b896d4b237 PTY: Disallow infinite writing to slaves. 
This way we don't buffer ungodly amounts of output in the kernel when doing
e.g "cat /dev/random" on a PTY.

d7d78670c9 Kernel: Add some logging for backing store get/release syscalls. 2019-01-25 00:13:37 +01:00
Andreas Kling
86eae0f8df Let userland retain the window backing store while drawing into it. 
To start painting, call:
gui$get_window_backing_store()

Then finish up with:
gui$release_window_backing_store()

Process will retain the underlying GraphicsBitmap behind the scenes.
This fixes racing between the WindowServer and GUI clients.

This patch also adds a WSWindowLocker that is exactly what it sounds like.

ccf3fc4618 TTY: MasterPTY's are always writable when open. 
This should probably have some limitations eventually, but for now let's just
say we always accept data for shoveling over to SlavePTY.
