I know on 2.6, I seem to be able to do
something like this to correlate PCI
(domain)/bus/dev/func with the linux
assigned scsi host number.
myhost:/sys/bus/scsi/devices # find /sys/devices -name 'host[0-9]*' -print
/sys/devices/pci0000:64/0000:64:01.1/host15
/sys/devices/pci0000:64/0000:64:01.0/host14
/sys/devices/pci0000:62/0000:62:01.1/host11
/sys/devices/pci0000:62/0000:62:01.0/host10
/sys/devices/pci0000:60/0000:60:03.1/host9
/sys/devices/pci0000:60/0000:60:03.0/host8
/sys/devices/pci0000:60/0000:60:02.1/host7
/sys/devices/pci0000:60/0000:60:02.0/host6
/sys/devices/pci0000:38/0000:38:01.1/host5
/sys/devices/pci0000:38/0000:38:01.0/host4
/sys/devices/pci0000:34/0000:34:01.1/host13
/sys/devices/pci0000:34/0000:34:01.0/host12
/sys/devices/pci0000:20/0000:20:03.1/host3
/sys/devices/pci0000:20/0000:20:03.0/host2
/sys/devices/pci0000:20/0000:20:02.1/host1
/sys/devices/pci0000:20/0000:20:02.0/host0
Is there any generic way to make the same sort
of correlation on 2.4 kernels?
I know I can do, for instance,
myhost:/sys/bus/scsi/devices # cat /proc/scsi/sym53c8xx/0
Chip sym53c1010-66, device id 0x21, revision id 0x1
At PCI address 0000:20:02.0, IRQ 50
Min. period factor 9, Wide SCSI BUS, DT capable
Max. started commands 448, max. commands per LUN 64
And so correlate scsi host 0 with "PCI address 0000:20:02.0"
However, that is of course different from driver to driver,
(on many the PCI info is not apparently available)
and even from version to version of the same driver, e.g:
here's a different version:
[EMAIL PROTECTED] sym53c8xx]# cat /proc/scsi/sym53c8xx/0
General information:
Chip sym53c1010-66, device id 0x21, revision id 0x1
On PCI bus 33, device 1, function 0, IRQ 52
Synchronous period factor 9, max commands per lun 32
So, is there any way that's not so hit-or-miss?
Thanks,
