Jesus Sanchez-Palencia	afd9b5b0b7	x86: Add APIs to 8259 PIC driver This commit implements pic_eoi(int irq) and a helper macro PIC_INT(irq). This first checks which PICs should be 'acked' given an IRQ number, while the macro returns the actual system interrupt number for the IRQ according to the offset used on the PIC initialization.	2015-12-21 08:06:14 -02:00
Andre Guedes	826ff7cb29	x86: Add pic_unmask_irq() helper This patch implements the pic_unmask_irq() helper and uses it where applicable. This function zeros the corresponding bit from the IRQ number in IMR register. This patch doesn't implement the pic_mask_irq() helper since it is not useful at this moment.	2015-12-21 08:06:14 -02:00

x86: Add APIs to 8259 PIC driver

This commit implements pic_eoi(int irq) and a helper macro PIC_INT(irq).
This first checks which PICs should be 'acked' given an IRQ number, while
the macro returns the actual system interrupt number for the IRQ according
to the offset used on the PIC initialization.

x86: Add pic_unmask_irq() helper

This patch implements the pic_unmask_irq() helper and uses it where
applicable. This function zeros the corresponding bit from the IRQ
number in IMR register.

This patch doesn't implement the pic_mask_irq() helper since it is not
useful at this moment.
