Idan Horowitz	172d23deae	Kernel: Convert PCI Capability struct to class with convenience methods ... Based on pull #3236 by tomuta Co-authored-by: Tom <tomut@yahoo.com>	2021-04-17 10:21:23 +02:00
Liav A	cf0a12c68f	Kernel: Add various methods to handle interrupts in the PCI subsystem ... For now, we only are able to enable or disable pin based interrupts. Later, when implemented, we could utilize MSI & MSI-X interrupts.	2020-12-21 00:19:21 +01:00
Liav A	9d10eb473d	Kernel: Add the DeviceController class in the PCI subsystem ... Such device is not an IRQHandler by itself, but actually a controller of many IRQ or MSI devices. The purpose of this class is to manage multiple sources of interrupts. For example, a generic ISA IDE controller controls 2 IRQ sources - 14 and 15. So, when we initialize the IDE controller, it will initialize two IDE channels (also known as PATAChannels) to utilize IRQ 14 and 15, respectively. NVMe with MSI-X support can theoretically handle up to 2048 interrupts.	2020-12-21 00:19:21 +01:00
