The // comments in the mtrr code. Now fixed. 2. A query about when Xen can support PAT. In progress; when its done, we can remove the unconditional PAT disable. for-ingo/xen/dom0/pci for-ingo/xen/dom0/swiotlb Updated with Joerg Roedel, FUJITA Tomonori and Matthew Wilcox's comments, Acked-by and Reviewed-bys as appropriate. for-ingo/xen/dom0/apic-ops After discussion between yourself and HPA, we resolved that using io_apic_ops was the right way to go forward with this. I replaced for-ingo/xen/dom0/apic with the new branch for-ingo/xen/dom0/apic-ops, which is identical aside from implementing and using io_apic_ops. for-ingo/xen/dom0/mtrr You queried the value of "extending" this interface, given that its considered to be deprecated. These changes in no way extend the interface, but just make the existing interface functional under Xen. And while we don't have PAT support, there's no other way of setting cachability attributes on memory, so not supporting it has a fairly severe performance impact on things like X. Aside from some whitespace issues around some Impact: lines, I don't know of any outstanding problems. (I just pushed an updates to these branches to fix those, and fold a change to address Jesse's comment.) Please tell me if you have any further issues which prevents you from pulling these changes. Otherwise I'd appreciate it if you pulled them soon, as we're already on -rc5, and I have more changes I'd like to prep for the next merge window. Thanks, J
