Hello,
I have been using the add_drv command as below to load PCI adapter driver
(called qla).
"add_drv -v -i '"pci1077,3022"' -m '* 0666 root sys' -n qla"
where the 1077 is the value of PCI vendor_id register (00h of PCI register
sets) and 3022, the PCI device_id(02h). This command works well for almost all
PCI boards on both x86 and SPARC machines.
However, I just got a new board and though this board's Vendor ID and Device ID
are also 1077 and 3022, the "prtconf" command shows that the board is somehow
recognized as :
pci1014,36f, instand #xx
where the 1014 and 36f are PCI Subsystem Vendor Id and Sub system Id register.
And I have to use the following script to load driver.
"add_drv -v -i '"pci1014,36f"' -m '* 0666 root sys' -n qla"
But this script works only on x86 not SPARC.
I don't why I have to use Sub System vendor Id and Sub System ID to load driver
for some boards and why this works on x86 only?
Can someone help me?
