From 58e26c74e085d6a52d26ec950f1aaf711c3ef0b1 Mon Sep 17 00:00:00 2001 From: Timothy Pearson Date: Thu, 4 Jun 2015 13:35:45 -0500 Subject: northbridge/amd/amdfam10: Increase MMIO hole size to 1GB On modern mainboards with multiple PCI-e devices and a single graphics card the default MMIO hole size of 512M is inadequate, leading to resource-hungry PCI-e devices (such as an external graphics card) being assigned invalid MMIO ranges. This, in turn, causes the entire PCI subsystem to become unavailable, leading to a failure to boot. TEST: Booted KGPE-D16 with NVIDIA 7300LE and verified proper operation of PCI/PCI-e devices, including text mode VGA operation via the add-on card and its VGA option ROM.
