Hi Ian, There have been a lot of interest on gfx passthru recently. This patch enables ATI VBIOS in passthru mode. The guest VM system BIOS (including Windows boot logo) can now show in passthru screen. We have tested with various Windows and Linux guest VMs. Please help review it. We are also looking forward to comments and suggestions from Xen community users. Signed-off-by: Wei Huang

Future AMD SVM supports a new feature called flush by ASID. The idea is to allow CPU to flush TLBs associated with the ASID assigned to guest VM. So hypervisor doesn''t have to reassign a new ASID in order to flush guest''s VCPU. Please review it.

I am adding interrupt support for LWP, whose spec is available at http://support.amd.com/us/Processor_TechDocs/43724.pdf. Basically OS can specify an interrupt vector in LWP_CFG MSR; the interrupt will be triggered when event buffer overflows. For HVM guests, I want to re-inject this interrupt back into the guest VM. Here is one idea similar to virtualized PMU: It first registers a special

Hi Evgeny, Quentin and Matthias found it was a problem about subreg live range update and will push a fix soon (http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20170123/424126.html).

Some firmware, such as OVMF relies on this value to get the size of extra memory above 4GB. Seabios in Xen doesn''t need this as it gets e820 directly from Xen. Rombios doesn''t read this value.

RFC v2 of this series This series implements a basic test job for OVMF guest. The test case will install an OVMF guest and try to boot it. It is also possible to derive a debian HVM installation test case from ts-ovmf-debian-install - the only difference should be the BIOS option. I tested running the test script without specifying BIOS, it worked fine. I just didn''t figure out a

Implement a simple Xen APIC module and use it to deliver MSI/MSIX for Xen HVM guests.

This sounds right to me. If there is no objection, I will implement a patch to enforce this in langref and IR verifier. -----Original Message----- From: Friedman, Eli [mailto:efriedma at codeaurora.org] Sent: Tuesday, September 25, 2018 3:07 PM To: Pan, Wei <wei.pan at intel.com>; Reid Kleckner <rnk at google.com> Cc: llvm-dev <llvm-dev at lists.llvm.org> Subject: Re:

Hi Wei, Thank you for information. Please let me know about any progress in fixing the failures. I can help with checking that the final patch gives the same level of performance improvements.
