Revision f32ab7547161b9fa7ebfbc4f18ea1eb3fd49fe25 authored by =?UTF-8?q?Christian=20K=C3=B6nig?= on 11 January 2018, 13:23:29 UTC, committed by Bjorn Helgaas on 11 January 2018, 17:22:39 UTC
Only try to enable a 64-bit window on AMD CPUs when "pci=big_root_window" is specified. This taints the kernel because the new 64-bit window uses address space we don't know anything about, and it may contain unreported devices or memory that would conflict with the window. The pci_amd_enable_64bit_bar() quirk that enables the window is specific to AMD CPUs. The generic solution would be to have the firmware enable the window and describe it in the host bridge's _CRS method, or at least describe it in the _PRS method so the OS would have the option of enabling it.
