I am preparing a new server for production use. It is dual Opteron Tyan S2882 motherboard containing 2 1000BaseTX NICs and 2 SCSI controllers onboard. Running 5.3-RELEASE-p5 (i386).
The interrupt assignment performed by ACPI looks kinda strange:
$ ps -ax
[irq24: bge0 ahd0]
[irq25: bge1 ahd1]
I actually want NICs and SCSI controllers run in different kernel threads.
$ pciconf -lv
ahd0@pci2:6:0: class=0x010000 card=0x005e9005 chip=0x801d9005 rev=0x10 hdr=0x00
vendor = 'Adaptec Inc'
device = 'AIC-7902B Ultra320 SCSI Controller'
class = mass storage
subclass = SCSI
ahd1@pci2:6:1: class=0x010000 card=0x005e9005 chip=0x801d9005 rev=0x10 hdr=0x00
vendor = 'Adaptec Inc'
device = 'AIC-7902B Ultra320 SCSI Controller'
class = mass storage
subclass = SCSI
bge0@pci2:9:0: class=0x020000 card=0x164414e4 chip=0x164814e4 rev=0x03 hdr=0x00
vendor = 'Broadcom Corporation'
device = 'BCM5704 NetXtreme Dual Gigabit Adapter'
class = network
subclass = ethernet
bge1@pci2:9:1: class=0x020000 card=0x164414e4 chip=0x164814e4 rev=0x03 hdr=0x00
vendor = 'Broadcom Corporation'
device = 'BCM5704 NetXtreme Dual Gigabit Adapter'
class = network
subclass = ethernet
All the devices are assigned IRQ10 in BIOS and I didnt found a way to change the settings there.
I have found a year-old discussion on -current
http://lists.freebsd.org/pipermail/freebsd-current/2004-January/019964.html
about assigning physical IRQ lines to PCI devices; so I want to know if there is a way to force ACPI assign virtual interrupts a similar way.
