Bananymous 5630f64175 Kernel: Add 16 more irq handlers 
IDT will now panic if trying to assing handler for non supported
irq.

Bananymous 39be6ab099 Kernel: Add temporary terminal output before controlling terminal 
Starting work on getting this boot on real hardware.

Bananymous 773dcdd3a2 Kernel: Check whether ELF address space can be loaded 
Before reserving address space in SYS_EXEC verify that ELF address
space is actually loadable. For example when trying to execute the
kernel binary in userspace, binarys address space would overlap with
current kernel address space. Now kernel won't crash anymore and
will just send SIGKILL to the process calling exec*().

Bananymous f0820e6f24 Shell: Fix parsing $ with unknown character 2023-10-12 22:24:27 +03:00
Bananymous a2b5e71654 Kernel: Implement AHCI driver 
SATA drives can now be used with banan-os. This allows much faster
disk access (writing 10 MiB from 30s to 1.5s). This can definitely
be optimized but the main slow down is probably the whole disk
structure in the os.

AHCI drive is now the default when running qemu.

Bananymous d2cfc843e4 BAN: Optional can now be constructed from another Optional 
Also fix bug in release_value() where we did not call the
destructor.

Bananymous 521513bed2 Kernel: make DMARegion::create static and fix mapping 2023-10-08 18:18:36 +03:00
Bananymous 400db176d1 Kernel: fix some math in physical ranges 
I allocated 1 bitmap page per 8 data pages. Bitmap page can actually
store 8*PAGE_SIZE data pages.

Also properly set last bits in bitmap. I did not care about endianness
but now we set the bits on unsigned long longs instead of bytes.

Bananymous 211cad03ff Kernel: Implement bare boness DMA Region 
This does nothing but allocate contiguous physical and virtual memory
and map it as CacheDisable. Also memory is automatically freed RAII style.
 2023-10-08 02:57:22 +03:00
Bananymous 8a9816d6e0 Kernel: Add API for getting contiguous physcial pages 
This will be used to create DMA regions.

Bananymous 03d2bf4002 Kernel: Rework physical memory allocation 
PhysicalRange is now much simpler bitmap. This makes expanding
PhysicalRange API much easier.

Bananymous f071240b33 Kernel: Fix PCI BarRegion offsets 
Calculations accidentally assumed bar registers are 8 byte instead
of 4.

Bananymous 27364f64a6 Kernel: Rework whole ATA driver structure 
Make ATA driver more compatible when we are adding SATA support
 2023-10-08 02:50:23 +03:00
Bananymous bcf62c5f2e Kernel: Rework interrupt mechanism 
All interruptrable classes now inherit from Interruptable which
has methdo handle_irq which is called on a interrupt.
