efibootmgr, not happy...

by Richard Henwood

Hi All, I have Ubuntu installed from Dmitri's installer. update-grub2 works well from that OS. I now have Fedora Rawhide in a separate partition and I would like to do have Fedora take over efi management. I have read through a bit about EFI management on Linux and it looks like efibootmgr is the primary tool. Using efibootmgr from both Ubuntu 19.10 and Fedora Rawhide and I get identical errors: $ efibootmgr -c -d /dev/sda -p 1 -l \\EFI\\fedora\\grubaa64.efi -L skipping unreadable variable "Boot0000": Invalid argument Could not prepare Boot variable: Invalid argument Does anyone have a suggestion for the next steps for me to try? best regards, Richard -- Richard.Henwood(a)arm.com IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.

efi=novamap query

by Richard Henwood

Hi All, A fellow laptop user has been looking into efi=novamap requirement. I was sharing with him that I thought only firmware could solve this problem and he has questioned me on that assertion and pointed me to this commit: https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=4e46… It appears from my reading that efi=novamap is required because: It is fiddly to make the kernel function SetVirtualAddressMap() work correctly on AArch64. Without documentation for the laptops I care about, it does not appear to be a valuable use of time to make SetVirtualAddressMap() work. For now, efi=novamap is a good-enough work-around. Is that more a more accurate analysis on my part? best regards, Richard -- Richard.Henwood(a)arm.com Server Software Eco-System Tel: +1 512 410 9612 IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.

Config suggestions for Fedora Rawhide 5.5/6 kernel?

by Richard Henwood

Hi all, I am playing with the Fedora Rawhide aarch64 kernel on my lenovo c630. Today this is a 5.6 kernel. I guess it is missing some config options stuff because the laptop keyboard isn't available. It also seems like systemd userspace is pretty unhappy too, but that is seconday to the keyboard for me currently. I haven't spent time looking though the know working configs that are already available, but appealing to the knowledge on this list: are there some kernel config options folks can suggest to me to improve the situation?

New ARM laptops with lower prices

by russianneuromancer＠ya.ru

Hello! I guess this could be interesting information for subscribers - there is few new Snapdragon-based laptops with lower prices: PiPo clamshell for 250 USD and 2-in-1 for 350 USD: https://www.youtube.com/watch?v=dsEss_vj_XY (it seems like MateBook clone is called PiPo N123) JP.IK Turn T101 for 300 USD and Positivo Wise N1212S for 575 USD: https://educationblog.microsoft.com/en-us/2020/01/our-vision-to-close-the-b… Weibu will release a few cheap models: https://mspoweruser.com/wave-of-low-cost-windows-10-on-arm-laptops-finally-… I not sure where to buy PiPo and Weibu laptops, but hopefully JP.IK Turn T101 and Positivo Wise N1212S will be available at Microsoft Store soon. There is also Huawei MateBook E 2019 with a bit higher price, but unique spec - 512 GB UFS: https://www.ebay.com/itm/303150026056 (it seems like currently MateBook E 2019 available only via eBay, AliExpress and Huawei own store https://www.vmall.com/product/10086276516577.html?cid=91245 ). Spec: https://consumer.huawei.com/cn/laptops/matebook-e/specs/ Interestingly, it seems like MateBook E 2019 sold only with US keyboard layout, which is kind of unexpected for laptop sold only in China. At least I didn't managed to found SKU with any other keyboard layout. Even hands-on reviews in Chinese show only US keyboard: https://post.smzdm.com/p/aoow02g9/ https://www.zhihu.com/question/319701244

Lenovo Miix 630 possible hardware issue verification

by russianneuromancer＠ya.ru

Hello! I received Lenovo Miix 630-12Q35 today, and to my surprise, there is no audio even in preinstalled system, even after OS reset via Troubleshooting section of Windows bootloader. As "Qualcomm(R) Aqstic(TM)" and "Qualcomm Audio DSP Subsystem Device" devices is preset in "System devices" section of Device Manager, and there is no errors from these two drivers, I believe this could be a software issue with Qualcomm drivers for Windows. I tried to add "Qualcomm(R) Aqstic(TM)" (as Sound device, not System device) manually (via "Action" > "Add legacy hardware" menu item in Device Manager) but this does not help - Aqstic audio inputs/output does not appear in Device Manager, so it's still impossible to verify if audio actually working or not. Obviously, I don't want to keep the defective unit on hands and would like to find out if audio hardware actually works, or there is something broken in hardware which means audio stay non-working even when Qualcomm Aqstic get supported by aarch64-laptop project. So I wondering if there was any progress with Qualcomm Aqstic support in Linux on these laptops? Even if there are preliminary patches and UCM draft that allow testing at least part of hardware (speaker or microphone or audio jack) that would be a great help in this case, so I at least will be able to find if the hardware works.
