Bananymous a9c10d0751 Base: add empty directories with .gitkeep to base/ 2023-07-11 08:02:28 +03:00
Bananymous 74c79c7eff Kernel: Rewrite whole device structure 
We now have DevFileSystem which is derived from RamFileSystem. All
devices are RamInodes. We don't have separate DeviceManager anymore.
To iterate over devices, you can loop througn every inode in devfs.

Bananymous 45789fda08 Kernel: You can now read/write to RamInodes

Bananymous 0d620f3e0f Kernel: Rewrite and optimize DiskCache 
DiskCache now consists of PageCaches which are caches of contiguous
sectors. This allows the disk cache to be ordered and faster traversal.

We seem to have a problem somewhere during reading. The stack gets
corrupted.

Bananymous 10544db52e LibELF: We use BAN::Vector<uint8_t> as elf storage 
This is made possible by the dynamic kmalloc
 2023-06-18 23:29:23 +03:00
Bananymous 5e123031aa Kernel: kmalloc has now somewhat dynamic storage 
Allocations bigger than PAGE_SIZE and those not forced to be identity
mapped are now done on a GeneralAllocator. This allows us to use kmalloc
for big allocations; bigger than the fixed 1 MiB storage.

This is still a hack and the whole kmalloc will have to be rewritten at
some point, but for now this does the job :D
