Bananymous 96767f5ca8 Kernel: Implement PCI interrupt routing 
This does not really work but I have no idea what I'm doing wrong

Bananymous 22b32a0fe5 Kernel: Expose PCI interrupt mechanism from PCIDevice 2025-02-10 22:57:25 +02:00
Bananymous 2d11ce9669 Kernel: Fix interrupt system 
I had not understood how MSIs work and I was unnecessarily routing them
through IOAPIC. This is not necessary and should not be done :D

Also MSIs were reserving interrupts that IOAPIC was capable of
generating. Now IOAPIC and MSIs use different set of interrupts so
IOAPIC can use more interrupts if needed.

Bananymous 368f5e9799 Kernel: Add command lineoption `nousb` that will disable usb controller 2024-08-16 22:09:24 +03:00
Bananymous 08cbd009ac Kernel: PCI don't report multi function bit with header_type() 2024-06-29 22:11:55 +03:00
Bananymous 2a4d986da5 Kernel: Add preliminary support for PCIe 
Only segment 0 is supported, but devices can now be accessed through
mmio.

Adding more segments would require adding argument to every PCI API so
it is left for later.

Bananymous 0fdf8b6f68 Kernel: Fix PCI bugs 
IO BarRegion used vaddr instead of the correct paddr. Add API for
memory region iobase query.

Bananymous a740bf8df4 1000th COMMIT: Kernel: Add basic E1000 driver

link status

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.
