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.
