hi All,
Mailing list created! Welcome all!
My notes from talking to Lee this week --------------------------------------
- ACPI: - UFS patches have been sent upstream. - With a patch, battery and AC power detection work!
- General - It seems ISO9660 images will boot, but only from USB 3.1 dev. - Unable to reproduce the trackpad problems - it works fine now. - Maybe this is because of a firmware update?
Distros:
- Ubuntu - 18.04: missing grub 4k alignment patch. - 19.04: boots to grub, kernel does not boot. - Leif's
- openSUSE - missing grub 4k alignment patch.
- Fedora Rawhide - grub boots. Installer hangs with '_' (see below)
Open task items for this week's update --------------------------------------
Please ping this list to share your interest in items so we can avoid duplication of effort.
- Linux support for ACPI PNP0D80 (PEP) - The PNP0D80 is a System Power Management Controller - Very little support resides in Linux at the moment - Thus no ACPI Power Management can currently take place - Accelerated Graphics also depends on it
- UEFI Boot Variables investigation - Grub fails to manipulate them during install - Is it possible for Linux to change them at run-time?
- DMA crash investigation - CRASH IMAGE: https://photos.app.goo.gl/2MGJEALZMyoowr9d6 - HACK PATCH: https://tinyurl.com/y5cnln2j
- Upstream Kernel ACPI check - ACPI tables incorrectly advertise themselves as v5.0 - Kernel should check the presence of PSCI instead - PATCH: https://tinyurl.com/yyq76m47 - NB: Assuming Ard will handle this - needs to be done soon
- Upstream ACPI Battery and AC Power support - Simply a matter of not depending on CONFIG_X86 - PATCH: https://tinyurl.com/yx9kf7e8 - NB: Assuming Ard will handle this - needs to be done soon
- Debug Fedora Rawhide - Kernel currently boots to a black screen with white '_' - NB: Assuming Peter will handle this
- Create UEFI module for persistently loading DTB - We have one which handles this for a single boot - NB: Assuming Leif will handle this
- Test ISO9660 based installers booting from USB - Must be done by someone who has not updated Windows - Fedora Rawhide ISO is a good image to use for testing - LINK: https://tinyurl.com/y2l6bvp9 - If it boots to the Fedora (Grub) menu, it works - Current belief is that USB 3.1 sticks are required - Need to test USB 2.0 and 3.0 sticks too
- Create and upstream a Live Arch Linux ISO/installer for AArch64 - AArch64 support is provided by copying a pre-built roofs to UFS - This is clunky and needs a proper installer like other distos - Get in touch with Richard Henwood directly if you can help.
best regards, Richard
