Can any hardware guru's tell me if it's okay to share an interrupt in
linux? I remember back in the DOS/Win days that you couldn't have a
device on the same interrupt (serial ports, etc)... but that was back
before PCI, PNP, etc... I've got 3 devices on the same interrupt as
follows:
[root at proto1 root]$ lspci -v
(edited for brevity)
00:0d.0 Network controller: Harris Semiconductor Prism 2.5 Wavelan
chipset (rev 01)
Subsystem: Unknown device 1737:3874
Flags: bus master, medium devsel, latency 32, IRQ 11
Memory at d8008000 (32-bit, prefetchable) [size=4K]
Capabilities: [dc] Power Management version 2
00:11.0 Multimedia audio controller: Yamaha Corporation YMF-744B [DS-1S
Audio Controller] (rev 02)
Subsystem: Yamaha Corporation DS-XG PCI Audio CODEC
Flags: bus master, medium devsel, latency 32, IRQ 11
Memory at d8000000 (32-bit, non-prefetchable) [size=32K]
I/O ports at d000 [size=64]
I/O ports at d400 [size=4]
Capabilities: [50] Power Management version 1
01:00.0 VGA compatible controller: Matrox Graphics, Inc. MGA G400 AGP
(rev 04) (prog-if 00 [VGA])
Subsystem: Matrox Graphics, Inc. Millennium G400 MAX/Dual Head 32Mb
Flags: bus master, medium devsel, latency 32, IRQ 11
Memory at d2000000 (32-bit, prefetchable) [size=32M]
Memory at d4000000 (32-bit, non-prefetchable) [size=16K]
Memory at d5000000 (32-bit, non-prefetchable) [size=8M]
Expansion ROM at <unassigned> [disabled] [size=64K]
Capabilities: [dc] Power Management version 2
Capabilities: [f0] AGP version 2.0
Is this okay? Or do I have a problem here?
Thanks in advance for replies...
