Subject: [RFC v2 0/3] I/O Hook: Method for emulating h/w events
Newsgroups: gmane.linux.kernel
Date: Thursday 1st August 2013 10:31:30 UTC (over 3 years ago)
Hi Bjorn,

In this v2, I made the following changes according to your suggestion:

	1) The iohook driver is now built-in so we have alot fewer exported
	   symbols. But we still need to export two functions because the
	   loadable modules need to call into the I/O Hook.
	2) Non-PCI part moved from drivers/pci into drivers/misc/iohook
	3) It's now platform neutral. The PCI part should now work on all
	   platforms. The memory mapped I/O part can be easily extened later
	   to non-x86 platforms by modifying their part under arch/

I tested this new version on Westmere-EX. It worked as expected.

Regards,
