[PATCH 0/4] PCI: fix cardbus and sriov regressions
From: Ram Pai
Date: Mon Jun 20 2011 - 18:47:37 EST
The following patch-set fixes regressions caused by:
the commit "PCI: update bridge resources to get more big ranges when allocating space (again)"
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.
