Hi Ingo,
Over the last week or so, I've set out pull requests for the following
branches in git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git :
for-ingo/xen/dom0/core
You made two comments about the first post of this set:
1. 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
