From 20f83d56561879045ecade24d51e79dfb151baf6 Mon Sep 17 00:00:00 2001 From: Paul Menzel Date: Tue, 11 Feb 2014 10:38:27 +0100 Subject: intel/*/acpi: Increase range length of MCHBAR buffer to 32 kB MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Linux kernel 2.6.31 reports the warning below on Intel Ivy Bridge (with FSP). resource map sanity check conflict: 0xfed10000 0xfed17fff 0xfed10000 0xfed13fff pnp 00:01 Since Sandy Bridge the length of the MCHBAR is 32 kB and it is already used that way in other places. $ more src/northbridge/intel/fsp_sandybridge/acpi/hostbridge.asl […] OperationRegion (MCHB, SystemMemory, DEFAULT_MCHBAR, 0x8000) […] So instead of 16 kB specify that 32 kB are decoded in that memory range for Intel Sandy Bridge, Ivy Bridge and Haswell. (Linux kernel 3.10 does not warn about that.)
