9fa8d4e22f WindowServer: Rename the two painting phases. 
Work now happens in terms of two messages:

    - WM_ClientWantsToPaint
    - WM_ClientFinishedPaint

This feels fairly obvious compared to the old Paint/Invalidate.

bba21adae3 WindowServer: Rename WSEvent to WSMessage. 
Also do the same for WSMessageLoop and WSMessageReceiver. More to come.

7cf3c7461c Refactor GUI rendering model to be two-phased. 
Instead of clients painting whenever they feel like it, we now ask that they
paint in response to a paint message.

After finishing painting, clients notify the WindowServer about the rect(s)
they painted into and then flush eventually happens, etc.

This stuff leaves us with a lot of badly named things. Need to fix that.

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

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.

0ebaa35aa1 Kernel: Let the process argv arrays be null-terminated. 
Seems like this is expected. I don't know why I thought it wasn't.

8bb18fdc56 Kernel: Get rid of Unix namespace. 
This is no longer needed as the Kernel can stand on its own legs now
and there won't be any conflict with host system data types.

e911caeb10 Kernel: Fix dumb race in Scheduler::yield() debug code. 
It was perfectly possible for Scheduler::yield() to get interrupted after
setting s_in_yield but before disabling interrupts.

bda0c935c2 Add unlink() syscall and /bin/rm. 
This patch adds most of the plumbing for working file deletion in Ext2FS.
Directory entries are removed and inode link counts updated.
We don't yet update the inode or block bitmaps, I will do that separately.

2f2f28f212 Kernel: Refactor Region/PageDirectory ownership model. 
Make PageDirectory retainable and have each Region co-own the PageDirectory
they're mapped into. When unmapped, Region has no associated PageDirectory.

This allows Region to automatically unmap itself when destroyed.

51595603bd WindowServer: Rename WSEvent subclasses WSFooEvent for consistency. 
Add a WSWindowInvalidationEvent that carries a rect instead of having an
awkward single-purpose rect in WSEvent.
Flesh out WSKeyEvent a bit more.

76a2881793 Mark the two Regions used GraphicsBitmaps as explicitly shared. 
This fixes a goofy problem where forking a GUI process would cowify the
GraphicsBitmap for everyone making a hue confusing mess.

I'm not in love with this syscall API but it allows me to make progress.
