Running a Windows guest on a i915-GVTg_V4_2 from an HD 5500 IGD on
v5.12-rc6 results in host logs:
gvt: vgpu 1: lrm access to register (20c0)
gvt: vgpu 1: MI_LOAD_REGISTER_MEM handler error
gvt: vgpu 1: cmd parser error
0x0
0x29
gvt: vgpu 1: scan wa ctx error
gvt: vgpu 1: failed to submit desc 0
gvt: vgpu 1: fail submit workload on ring rcs0
gvt: vgpu 1: fail to emulate MMIO write 00002230 len 4
The guest goes into a boot loop triggering this error before reaching
the desktop and rebooting. Guest using Intel driver 20.19.15.5171
dated 11/4/2020 (from driver file 15.40.5171).
This VM works well with the same guest and userspace software stack on
Fedora's kernel 5.11.11-200.fc33.x86_64. Thanks,
Alex

Looks we didn't hit this one on Broadwell with recent testing. I'll double
check, maybe Broadwell missed something after our cmd parser rework.
Thanks for reporting!
