851de295eb Change pci_intr_map to get interrupt source information from a "struct 
pci_attach_args *" instead of from four separate parameters which in
all cases were extracted from the same "struct pci_attach_args".

This both simplifies the driver api, and allows for alternate PCI
interrupt mapping schemes, such as one using the tables described in
the Intel Multiprocessor Spec which describe interrupt wirings for
devices behind pci-pci bridges based on the device's location rather
the bridge's location.

Tested on alpha and i386; welcome to 1.5Q

2668e3b213 Switch to the new `evcnt' mechanism for counting interrupts. Maintain 
a per-CPU interrupt counter for clock, device, and interprocessor
interrupts.

cffb580806 Implement the more flexiable `evcnt' interface as discussed (briefly) on 
tech-kern and now documented in evcnt(9).

f785596e75 Add support for mapping the OHCI USB controller interrupt (which is wired toan ISA IRQ because it's in the same package as the PCI-ISA bridge). 2000-03-19 02:25:29 +00:00

de83dce0de On second thought, call that like the rest of the shared intr functions. 1998-07-07 22:24:38 +00:00

ca73507d0b The Pyxis core logic in the Miata seems to have problems with stray interrupts. 
Do what Digital UNIX (formerly DEC OSF/1) does; just ignore strays.

be83de18fd Use ALPHA_SHARED_INTR_DISABLE() to test if a shared interrupt should 
be disabled after a stray.

0890af5ca8 Only disable an interrupt line after MAXSTRAYs if there is no handler 
attached; we get stray interrupts on PCI devices sometimes, for some
unknown reason.  (Similar problem exists on the 164SX, which also has
a Pyxis.)

1aa688234e Miata 1 has an Intel SIO at bus 0 device 7 and a CMD PCI IDE at bus 0 
device 4.  Miata 1.5 and Miata 2 have a Cypress at device 7 and PCI IDE
at functions 1 and 2 of the Cypress (like the PC164SX).  These on-board
PCI IDE controllers are wired to compatibility mode, so don't bother
trying to map the interrupt.

c072110af0 Actually, I did use a few of them on this file (I wasn't clear enough 
in my mail to Ross, I guess...)

8f455480ef Tweak the copyrights a little bit. pci_550.h gets a TNF copyright, not 
CMU, and pci_550.c keeps TNF but gets "Andrew Gallatin and Jason R. Thorpe".

cbaedc8675 Support for the Digital Personal Workstation [456]xx, a.k.a. Miata (systype 
DEC_550).  Mostly cloned from the EB164 systype, with some modifications
from myself, and a few more from Andrew Gellatin.
