b95aa18315 Hook up the Keyboard device to the AbstractScreen. 
Basic text editing in a TextBox works. How very cool :^)

e5e295052f Hook up the PS2MouseDevice to the AbstractScreen+WindowManager. 
Render the mouse cursor by xor'ing the pixels. I don't know anything about
hardware cursors yet and this way we don't need to recompose the window
hierarchy every time you move the mouse. :^)

e740f1195a Add a simple PS/2 mouse device. 
It's not hooked up to anything just yet, but it does read movement deltas.

...yeah yeah, one day I'm gonna zero out the kernel's BSS segment. Soon..

f6d2c3ed87 Hook everything up to run the GUI on top of the kernel. 
Okay things kinda sorta work. Both Bochs and QEMU now boot into GUI mode.
There's a ton of stuff that doesn't make sense and so many things to rework.

Still it's quite cool to have made it this far. :^)

4775fd88e3 More window management work. 
- Fix inverted mouse event hit test z-ordering.
- Let the RootWidget backing store simply be the display framebuffer.

659c54e32b Switch into 1024x768x32bpp VESA LFB mode at boot. 
This is going to be pretty cool once I can hook up the Widgets/ code to it.

9963da9005 Start refactoring graphics system to have per-window backing stores. 
It was fun for everyone to share a single framebuffer but it was also
kinda really awful. Let's move towards having a "GraphicsBitmap" as the
backing store for each Window.

This is going to need a lot of refactoring so let's get started.

0d36281162 Refactor FS::find_parent_of_inode() into Inode::parent(). 
This way, Ext2FSInode can cache its parent inode index. This makes absolute
path lookups dramatically faster.
SynthFSInode is also simplified greatly.

7731aef7b2 Let the "reaped unparented process" messages go straight to the debugger. 2019-01-01 03:56:39 +01:00

eb78238032 Ext2FS: Don't worry about updating lookup caches in write_ext2_inode(). 
Instead, have Ext2FSInode worry about that when flushing.
Also tidy up in the inode bitmap accessors at the same time for some reason.
 2019-01-01 03:55:43 +01:00
Andreas Kling
8f9542174f Ext2FS: Don't cache a full Ext2FSInode object for non-existent inodes. 
This was a bit silly. We were always creating Ext2FSInode objects when
Ext2FSInode::get_inode() was called. They'd then sit and fatten up the
inode cache forever, despite not representing allocated inodes.

This patch consults the inode bitmap and if get_inode() is called with
an unallocated inode index, we simply cache a nullptr to represent the
fact that this index is unused.

This could be a lot better optimized, it will currently hit the disk for
every new inode index encountered.

d07b08a287 FS: Don't default to having a full InodeMetadata in every Inode. 
This allows Ext2FS to keep its own ext2_inode around instead.
 2019-01-01 03:16:36 +01:00
Andreas Kling
0cb074dc73 Ext2FS: On second thought, let's not uncache the Ext2FSInodes today.. 2019-01-01 02:52:21 +01:00
Andreas Kling
741349502f Ext2FS: Free Ext2FSInodes when the last user releases them. 
The inode cache was keeping these alive forever. Added a cute little magic
trick to Retainable that calls T::one_retain_left() when the retain count
is decremented to 1.
 2019-01-01 02:38:09 +01:00
Andreas Kling
42d9f18cae Remove the cheesy block cache from DiskBackedFS. 
This should be reimplemented with proper paging support. This approach was
mostly just chewing kmalloc memory.
 2019-01-01 02:27:05 +01:00
Andreas Kling
4b6a8f8a08 Unbreak ksym loading and make reading /proc/PID/stack not crash. 2019-01-01 02:20:01 +01:00

683185e4aa MM: Allocate page tables from a separate set of physical pages. 
The old approach only worked because of an overpermissive accident.
There's now a concept of supervisor physical pages that can be allocated.
They all sit in the low 4 MB of physical memory and are identity mapped,
shared between all processes, and only ring 0 can access them.
 2019-01-01 02:09:43 +01:00
Andreas Kling
a5ffa2eec7 Add a PageDirectory::flush() that does nothing if another PD is active. 
This way callers can just flush() every time after making any modification
and the PageDirectory itself will decide if TLB invalidation is necessary.

cc30407b8c Oops, errno codes need to be negative in the kernel. 2018-12-31 20:38:25 +01:00

9eca2ffd41 Make PhysicalPage eternally allocated. 2018-12-31 20:25:42 +01:00
Andreas Kling
3e37a1f5c3 Optimize PageDirectory destruction. 
Remove an extra hash lookup and only iterate over the actually-used
PhysicalPages that we need to clean up.
 2018-12-31 15:18:02 +01:00
Andreas Kling
edac1d6748 Make PageDirectory store physical pages in a HashMap. 
This container is really just there to keep a retain on the individual
PhysicalPages for each page table. A HashMap does the job with far greater
space efficiency.
 2018-12-31 15:10:12 +01:00
Andreas Kling
193ead94f8 Let PageDirectory have a PhysicalPage for the PDB instead of being the PDB. 
This is more efficient than using the wasteful kmalloc_aligned() approach
to allocation. It also allows much tighter encapsulation of the class.
