The workloads that were causing the issues I reported here no longer cause problems. It seems as stable as when using driver 25.20.100.6136. The only new thing I noticed were two QEMU errors in the terminal: qemu-system-x86_64: vfio_region_write(123f09b0-4c00-11e8-a6ca-f3c21e47e012:region0+0x24ec, 0x83a8,4) failed: Endereço inválido qemu-system-x86_64: vfio_region_write(123f09b0-4c00-11e8-a6ca-f3c21e47e012:region0+0x24ec, 0x83a8,4) failed: Endereço inválido "Endereço inválido" means "Invalid address". The first one appeared when upgrading the drivers and the second on reboot. dmesg is red with messages as: [14200.651340] gvt: guest page write error, gpa 11c643e90 which was generated when upgrading the driver. And: [14411.555755] gvt: vgpu 1: untracked MMIO 00004084 len 4 which appears in multiple circumstances as resolution changes. 4.18 and newer don't have this messages but <a class="bz_bug_link bz_status_NEW " title="NEW - System crashes seconds after a GPU hang with kernel newer than 4.18" href="show_bug.cgi?id=107945">https://bugs.freedesktop.org/show_bug.cgi?id=107945</a> is still present with 4.19-rc8 and drm-tip. The Windows 10 guest using iGVT-g is running very well, nearly everything I tried worked on it as it worked on Windows 10 host, only with a bit of overhead.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
