Our vGPU doesn't have a device ROM, we need follow the PCI spec to report this info to drivers. Otherwise, we would see below errors. Inspecting possible rom at 0xfe049000 (vd=8086:1912 bdf=00:10.0) qemu-system-x86_64: vfio-pci: Cannot read device rom at 00000000-0000-0000-0000-000000000001 Device option ROM contents are probably invalid (check dmesg). Skip option ROM probe with rombar=0, or load from file with romfile=No option rom signature (got 4860) I will also send a improvement patch to PCI subsystem related to PCI ROM. But no idea to omit below error, since no pattern to detect vbios shadow without touch its content. 0000:00:10.0: Invalid PCI ROM header signature: expecting 0xaa55, got 0x0000 Signed-off-by: Changbin Du <changbin.du@intel.com> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com> (cherry picked from commit c4270d122ccff963a021d1beb893d6192336af96) |

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
