[Touch-packages] [Bug 1872863] Re: QEMU/KVM display is garbled when booting from kernel EFI stub due to missing bochs-drm module
** Changed in: linux (Ubuntu Bionic) Status: In Progress => Fix Committed -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to kmod in Ubuntu. https://bugs.launchpad.net/bugs/1872863 Title: QEMU/KVM display is garbled when booting from kernel EFI stub due to missing bochs-drm module Status in kmod package in Ubuntu: Fix Released Status in linux package in Ubuntu: Fix Released Status in kmod source package in Bionic: In Progress Status in linux source package in Bionic: Fix Committed Bug description: BugLink: https://bugs.launchpad.net/bugs/1872863 [Impact] A recent grub2 SRU, LP #1864533, now forces the kernel to boot via the kernel EFI stub whenever EFI is enabled. This causes problems for QEMU/KVM virtual machines which use the VGA=std video device, as the efifb driver yields an unreadable garbled screen. See the attached image. The correct framebuffer driver to use in this situation is bochs-drm, and modprobing it from a HWE kernel fixes the issues. bochs-drm is missing from Bionic since CONFIG_DRM_BOCHS was disabled in LP #1378648 due to bochs-drm causing problems in a PowerKVM machine. This problem appears to be fixed now, and bochs-drm has been re-enabled for Disco and up, in LP #1795857 and has been proven safe. This has also come up again in LP #1823152, as well as chatter on LP #1795857 to get this enabled on Bionic. The customer which is experiencing this issue cannot switch to VGA=qxl as a workaround, and must use VGA=std, hence I suggest we re-enable bochs-drm for Bionic. [Fix] I noticed on Focal, if you boot, the framebuffer is initially efifb: [ 0.603716] efifb: probing for efifb [ 0.603733] efifb: framebuffer at 0xc000, using 1876k, total 1875k [ 0.603735] efifb: mode is 800x600x32, linelength=3200, pages=1 [ 0.603736] efifb: scrolling: redraw [ 0.603738] efifb: Truecolor: size=8:8:8:8, shift=24:16:8:0 [ 0.604462] Console: switching to colour frame buffer device 100x37 [ 0.605829] fb0: EFI VGA frame buffer device This soon changes to bochs-drm about a second later: [ 0.935988] bochs-drm :00:01.0: remove_conflicting_pci_framebuffers: bar 0: 0xc000 -> 0xc0ff [ 0.937023] bochs-drm :00:01.0: remove_conflicting_pci_framebuffers: bar 2: 0xc1c8c000 -> 0xc1c8cfff [ 0.937776] checking generic (c000 1d5000) vs hw (c000 100) [ 0.937776] fb0: switching to bochsdrmfb from EFI VGA [ 0.939085] Console: switching to colour dummy device 80x25 [ 0.939117] bochs-drm :00:01.0: vgaarb: deactivate vga console [ 0.939210] [drm] Found bochs VGA, ID 0xb0c5.

[Testcase] Create a new QEMU/KVM virtual machine, I used virt-manager. Before you install the OS, check the box to modify settings before install. In the "Overview" tab, enable EFI by setting the firmware to "UEFI x86_64: /usr/share/OVMF/OVMF_CODE.secboot.fd". Set the video device to qxl while you install Bionic. Once the install is done, reboot, do a "apt update" and "apt upgrade", to ensure you have grub2 2.02-2ubuntu8.15 installed. Shut the VM down, and set the video device to VGA. Or VGA=std if you use the QEMU command line. Start the VM up, and the screen will be garbled. See attached picture. If you install my test packages, which are available here: https://launchpad.net/~mruffell/+archive/ubuntu/sf272653-test Instructions to install (on a bionic system): 1) sudo add-apt-repository ppa:mruffell/sf272653-test 2) sudo apt-get update 3) sudo apt install linux-image-unsigned-4.15.0-96-generic linux-modules-4.15.0-96-generic linux-modules-extra-4.15.0-96-generic linux-headers-4.15.0-96-generic linux-headers-4.15.0-96 libkmod2 kmod 4) sudo reboot 5) uname -rv 4.15.0-96-generic #97+TEST272653v20200409b1-Ubuntu SMP Thu Apr 9 04:09:18 UTC 2020 If you reboot, the screen will be perfectly readable, since the bochs- drm driver will be in

I have run the two tests in a local VM and systemd-fsckd works there while tests-in-lxd seems to trip over the old flaky fellow being "boot-and-services". We had the discussion in the past, but I think I need to again bring up the suggestion to skip "tests-in-lxd" and "systemd-fsckd" until they are on reasonable success rates.

We've seen problems in the past with KVP daemons that looked very similar : https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1820063 [Test Case] There two main scenarios that need to be tested: 1. Azure instances: - Just start an azure instance using our Ubuntu images and check the the status of the hv-vss-daemon and hv-fcopy-daemon services using systemctl. - If the issue is solved they shouldn't be listed as failed. 2. Local Hyper-V VM: - Create a local Hyper-V instance and enable the two systemd services if necessary (hv-vss-daemon and hv-fcopy-daemon) and reboot. - You can change the integration services that are enable to the guest. 1. With desktop integration and the backup feature disabled, the hv-fcopy-daemon and the hv-vss-daemon service, respectively should not be listed as failed. 2. With the same features enabled the services should start without errors. [Regression Potential] The major risk with a potential regression is that those systemd service units are shipped by a package produced by our generic kernels and not the linux-azure kernel. So in case of a regression we might need to re-spin the generic kernels.

[Touch-packages] [Bug 1892358] Re: autopkgtest success rate dropped inhibiting proposed migration
Thank you @christian. I marked the Xenial test cases under this same bug, though can open a new bug and update the hint bug references if needed. I'll check back to see when/if ddstreet/rbalint have a chance to review. For the test results you're posting, I was wondering where you're getting those results from and an explanation of the results? xenial amd64 boot-and-services (F 45% f 0% S 0% B 5% => P 50%/) .FF...BFF.F. boot-smoke (F 80% f 0% S 0% B 5% => P 15%/) F.FF..BF systemd-fsckd (F 65% f 0% S 0% B 5% => P 30%/) FF.FFF.F..B.FF.F ppc64el no failures s390x no failures In the above, what does the F, f, B, & . stand for? Am I correct to assume the P *% is the pass rate? F for fail?
