From f483d3923dc3a6394c483e28ccb3fe700bdf399e Mon Sep 17 00:00:00 2001 From: Ram Pai Date: Thu, 7 Jul 2011 11:19:10 -0700 Subject: PCI: conditional resource-reallocation through kernel parameter pci=realloc Multiple attempts to dynamically reallocate pci resources have unfortunately lead to regressions. Though we continue to fix the regressions and fine tune the dynamic-reallocation behavior, we have not reached a acceptable state yet. This patch provides a interim solution. It disables dynamic reallocation by default, but adds the ability to enable it through pci=realloc kernel command line parameter.
