[PATCH 0/3] PCI: Fix hotplug memory distribute

From: Ilpo Järvinen

Date: Mon Nov 09 2026 - 09:47:43 EST


There are a few simple to fix issues within the code distributing the
available iomem (and ioport) space to bridges (to allow using it during
hotplug). The worst issue results in violating window granularity
(usually 1M for mem windows).

Ilpo Järvinen (3):
PCI: Fix NULL dereference when shrinking window without optional size
PCI: Fix start of available space for the next bridge during
distribution
PCI: Honor window granularity during resource distribution
