That's news to me. I didn't even realise it was possible to disable this.
Pointer?
Jon Masters told me this last week at FreedomHEC, so I don't have a
pointer to the patch that disables it, sorry.
Either there's some miscommunication, or bonghits.
(18:54:00:davej@gelk:kernel-2.6.18)$ kdiff vanilla/drivers/pci/pci-driver.c linux-2.6.18.noarch/drivers/pci/pci-driver.c
(18:54:10:davej@gelk:kernel-2.6.18)$
And as there's no CONFIG option other than CONFIG_HOTPLUG (which we obviously enable)
I don't see any reason why this wouldn't be enabled in RHEL5.
(And I think mdomsch would have probably had a fit if he found out we were
disabling it, but that's another story ;-)
Theres more to this than just PCI IDs though.
ac97 ID updates, usb id updates, etc, etc.
USB ids also can be added through sysfs :)
oh cool, I had missed that.
