mycroft fb60f2ced9 Turn off special mask mode by default. It is clearly not supported enough. 1993-12-05 11:20:09 +00:00
mycroft 3103af7e6b Take advantage of special mask mode by leaving interrupts masked in ISR until
they are serviced.  No need to frob IMR.

mycroft 1a2c258aa6 Enable chaining IRQ only if we're using an IRQ on the slave. Other minor
cleanup.

mycroft 44c93f17b5 Grumble. Just set the blasted ICU mode before every read. Also, send the EOIs
to the right port in isa_flushintrs().

mycroft b1c739de48 Need to change to reading ISR in isa_discoverintr(). 1993-10-31 20:11:31 +00:00
mycroft 58dd8e7222 Read ISR by default. If DIAGNOSTIC, display ISR and IRR status for stray
interrupts.

mycroft a4cf218142 Rearrange IDT initialization so it's easier to change ICU_OFFSET. 1993-10-31 18:36:21 +00:00
mycroft 757af3406e isa_discoverintr(): Also check ipending, in case the interrupt is being shared.
Use delay() for timeout rather than timer channel 2.

mycroft ebe64b7361 Reenable interrupts in ipending before resetting it. 1993-10-27 08:00:40 +00:00
mycroft 651d86ab91 Arrange that IF is on but we are at splhigh() during autoconfig. Clear
ipending in isa_flushintrs().

mycroft 32ee2e4e3f Stylistic change to IDT initialization. 1993-10-26 15:45:18 +00:00
mycroft 79682dc7fe Replace a %s with %x. 1993-10-26 14:22:41 +00:00
mycroft 3883efe0da Fix IDT initialization bug. Don't allow IRQ 0 to be autoconfigured. 1993-10-26 12:10:01 +00:00
mycroft 4b7f8b8a62 It does not make sense to mask a fastintr. 1993-10-22 19:33:13 +00:00
mycroft 0c9ce6ed1f New file with interrupt-handling code. Add intr_fasttrap(). 1993-10-22 19:27:40 +00:00
