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
PS. Don't forget to visit #aarch64-laptops on freenode IRC.
