This allows concurrent reads not fully reading the buffer not block
indefinately.

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.

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
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

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.
