From d71975ae6e0f3dc1c0c96d3a8cc0120a266305b9 Mon Sep 17 00:00:00 2001 From: Tuomas Tynkkynen Date: Mon, 14 May 2018 19:38:13 +0300 Subject: PCI: autoconfig: Don't allocate 64-bit addresses to 32-bit only resources Currently, if we happen to allocate an address requiring 64 bits to a device only supporting 32-bit BARs, the address eventually gets silently truncated to 32 bits. Avoid this by adding a new flag to pciauto_region_allocate() to bail out in such situations.
