Bananymous 5a8eb51968 Kernel: TTY now unblocks semaphore after read

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
 2023-06-18 23:27:00 +03:00

Bananymous 5dcc53bcf2 Kernel: Make disk IO blocking thread safe 
This was causing a lot of deadlocks on vms without kvm accel
 2023-06-12 18:57:47 +03:00
Bananymous 23543b15ca Kernel: Rework syscall calling 
I removed the intermediate function when calling syscalls. Now syscall
handler calls the current process automatically. Only exception is
sys_fork, since it needs a assembly trampoline for the new thread.
 2023-06-12 14:16:48 +03:00
