Subject: [git pull] PCI changes for 2.6.34
The following changes since commit
bee415ce427d1eab6cfb30221461c7d20cbf1903: Linus Torvalds (1):
Merge branch 'perf-fixes-for-linus' of
git://git.kernel.org/.../tip/linux-2.6-tip
are available in the git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6 linux-next
There are a few somewhat scary bits in this request:
- Bjorn's _CRS data changes
- Yinghai's resource reallocation code
- Rafael's runtime PM code
If you recall, we tried to enable _CRS last release and it caused
trouble, in particular because our existing code couldn't handle the
number of resources provided by some _CRS implementations. Bjorn's
fixed that though, and added code to use _CRS data by default on any
machine made in 2008 or later, which allows it to fix some existing
bugs on machines where pci=use_crs was previously required. Other bugs
requiring the old intel_bus.c code are also fixed by using _CRS by
default, now that the affected machines are running with production
firmware.
Yinghai's code also affects resource allocation. His patchset will
evaluate the resource tree at boot time looking for devices whose
resources couldn't be enabled because their upstream bridge window
wasn't large enough. If it find any, it'll free the associated
resources and re-try, attempting to get a large enough bridge window to
enable affected leaf devices. If that fails, it'll recurse higher into
the resource tree. With luck, it'll manage to make our resource
allocation code more effective by overriding over conservative BIOS
settings and giving Linux access to more device resources.
Finally there's Rafael's PM code. It should be in pretty good shape
now. There may be a few more ACPI changes on the way, but it's seen a
lot of testing in previous iterations, and has seen a lot of review as
well, so hopefully it won't cause any big problems.
Shortlog and diffstat below.
Thanks,
Jesse
