Subject: [PATCH 0/4] PCI: fix cardbus and sriov regressions
Date: Mon, 20 Jun 2011 15:47:13 -0700 [thread overview]
Message-ID: <1308610037-6261-1-git-send-email-linuxram@us.ibm.com> (raw)
The following patch-set fixes regressions caused by:
the commit "PCI: update bridge resources to get more big ranges when allocating space (again)"
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=da7822e5ad71ec9b745b412639f1e5e0ba795a20
patch 1/4: correctly calculates the additional resource size for hotplug bridges.
patch 2/4: ability to resize assigned pci-resource.
patch 3/4: makes SRIOV BARs a nice-to-have resource, which means resources will
be attempted to assign, but not gauranteed to succeed.
patch 4/4: makes cardbus bridge resources nice-to-have resource.
The regression was caused because on some platforms with limited i/o and mem
resources, the nice-to-have resources were allocated ahead of
absolutely-required resources, thus starving the latter. The patchset will
ensure that all the mandatory resource requirements are satisfied before any
nice-to-have resource requirements are satisfied.
