description |
For all(as I know) Huawei servers, the vga adapter are embed in the iBMC chips. Those server can install from ISO manually for 16.04.4 and screen display normally. But for 18.04 ( tested both for daily and final beta)version, the install screen is blur. One of tested server is Huawei 2855 v5, the certification link for 16.04 are https://certification.ubuntu.com/hardware/201707-25596/.
Below are key difference of dmesg. It seems might related with DRM.

[Impact]
amd64 based Huawei servers have problems where the display output of their iBMC chips is broken, resulting in a "blurry" screen when viewed from their in house remote kvm-like console.
Example:
https://launchpadlibrarian.net/365907668/creen_picture_for_blur.png
The issue is caused by the hibmc_drm kernel module being loaded. The PCI ID for the iBMC chips on amd64 hardware is the same as arm64 hardware, but the
hibmc_drm driver was developed only for use on arm64 hardware, most notably for the Huawei D05 development board.
The impact to Huawei is that their customers cannot use Ubuntu server install
media as the screen goes "blurry" when the d-i install media or subuqity
installer loads the hibmc_drm kernel module after language selection.
The only workaround for their customers is to press the "E" key during the very first installer menu and adding "modprobe.blacklist=hibmc_drm" to the kernel command line in the grub menu. This is not good for customer experience with their servers.
Other problems exist for the hibmc_drm driver on amd64, such as working on
bios, but not uefi, and not being wayland compatible, making the screen blurry whenever a desktop session is started and gdm loaded.
Huawei have asked us to remove hibmc_drm from all architectures except arm64,
and this aligns with advice from Hisilicon.
[Fix]
I modified the config/annotations file to remove all architectures except arm64, and created a patch for Kconfig to set a firm requirement on ARM64 for hibmc_drm.
I will send the Kconfig patch upstream in the coming days for a more permanent fix.
[Testcase]
Apply the patches and run:
ubuntu-bionic/CONFIGS$ fakeroot debian/rules genconfigs
ubuntu-bionic/CONFIGS$ grep -Rin "hibmc" .
./arm64-config.flavour.generic:5739:CONFIG_DRM_HISI_HIBMC=m
You should see that only arm64 has the config option enabled.
A test kernel has been built, and is available here:
https://launchpad.net/~mruffell/+archive/ubuntu/sf232667-test
Huawei requested a test d-i install iso to test server install with, which can be found here and uses the kernel from the ppa above:
https://people.canonical.com/~mruffell/sf232667_ubuntu_server_d-i_20190711b1.iso
Both the test kernel and the custom d-i install iso have been tested on amd64
Huawei server hardware successfully and video output is functional.
[Regression Potential]
Regressions will be limited to hardware containing the iBMC chips from Hisilicon, which I believe are exclusive to Huawei servers.
I have taken care to ensure that hibmc_drm is enabled for ARM64 so it should not impact kernels built for the Huawei D05 arm64 development board, and d-i will still load the hibmc_drm driver during startup for arm64. |
