This patch set mainly allows the user to build a seabios or rombios only version of hvmloader. In addition, when building a seabios only hvmloader, Option ROMs like vgabios and etherboot are no longer required, and therefore can be disabled from the build. Dependency on the bcc compiler can also be avoided the same way. v2: Separate patches for separate issues Introduced config option to

The OpRegion shouldn''t be mapped 1:1 because the address in the host can''t be used in the guest directly. This patch traps read and write access to the opregion of the Intel GPU config space (offset 0xfc). To work correctly this patch needs a change in hvmloader. HVMloader will allocate 2 pages for the OpRegion and write this address on the config space of the Intel GPU. Qemu

Basic x86 support [1] for running Linux as secondary Jailhouse [2] guest is currently pending in the tip tree. This builds on top and enhances the PCI support for x86 and also ARM guests (ARM[64] does not require platform patches and works already). Key elements of this series are: - detection of Jailhouse via device tree hypervisor node - function-level PCI scan if Jailhouse is detected -
