From 3622c0bf10ef273c7b530879d1a1af738d65ae66 Mon Sep 17 00:00:00 2001 From: Arthur Heymans Date: Thu, 12 Nov 2020 21:19:46 +0100 Subject: soc/intel/xeon_sp/cpx: Modify PCH_IOAPIC_BUS_NUMBER The PCH IOAPIC is not PCI discoverable. Linux checks the BDF set in DMAR against the PCI class if it is a PIC, which 00:1F.0 for instance isn't. The SINIT ACM on the other hand bails out with ERROR CLASS:0xA, MAJOR 3, MINOR 7 if the BUS number is 0.
