From: Julien Grall Date: Mon, 28 Sep 2015 13:14:23 +0000 (+0100) Subject: xen/pci: Don't build Xen pci code for ARM and ARM64 X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=refs%2Fheads%2Fcentos-dev;p=people%2Fjulieng%2Flinux-arm.git xen/pci: Don't build Xen pci code for ARM and ARM64 The PCI support for Xen doesn't compile on ARM/ARM64 when CONFIG_PCI_MMCONFIG=y: drivers/xen/pci.c:31:25: fatal error: asm/pci_x86.h: No such file or directory #include Although, Xen is not currently involved in PCI management for ARM/ARM64. There is plan to support it, but it would require some changes in Linux side. For now, introduce a new config options XEN_PCI which will be turned off for ARM platform.
