Bananymous 9bcfb34524 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 a0ecbed726 Kernel: You can now read/write to RamInodes
RamFS should be stored on physical pages and not in kmalloc, but
that will be implemented later :)

Bananymous 7d254c26bc 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 275a730485 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 9a7b2587af 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
