I've poked a few obvious places, and don't see these applied. Also is Yoga C630 going to be submitted on top of these? Or should I submit them?

Network Support in ASUS NovaGo TP370QL

by Saravanan Somasundaram

Hi, I was able to follow the instructions in the following article and get Ubuntu booted successfully. https://github.com/aarch64-laptops/build#Flashing-the-image I understood that wireless network is not supported yet. If i plugin a USB Wii-Lan Adapter, the adapter is not recognized as well. Is there any other adapters that's known to work with ASUS Novago Laptop ? Thanks, Saravanan

Re: [Aarch64-laptops] [PATCH v7 2/2] Add a module for retrieving SMBIOS information

We have the same kernel, and the same image bootable and usable across 4 different laptop models, with the only difference between them being the DTB to load. I was looking at how I can distinguish between the four models and automatically pick the right dtb. I did see these patches and was very sad when I found out that they didn't get merged. Thank you for rebasing these on top of v2.04. I will try to cherrypick them on top of Debian's experimental 2.04 grub and try to build an installer "that just boots" without requiring users to pick a particular dtb menuentry by hand. There are only dtbs in these images, and only one right one for each model. (Post install, we have flash-kernel mechanisms to continuously flash and use the right dtb, this is needed for the installer's grub to be able to detect models and thus boot the right dtb) Whilst these laptops might become dtb-free in the future, I expect new hardware to come out which would need dtb picker based on SMBIOS info again. -- Regards, Dimitri.

Firmware update (2.06) on c630

by Jason Allum

During a recent trip into windows-land, I noticed that Lenovo posted a firmware update for the c630. I downloaded and installed that, leaving my machine running 2.06. There don't appear to be any new menu options, and no description of the changes were available. I'm happy to run any diagnostic tooling for anyone that can't but is interested, if that information would be helpful to the cause.

[PATCH 0/5] drm+clk+genpd: support for bootloader enabled display

by Rob Clark

From: Rob Clark <robdclark(a)chromium.org> The aarch64 laptops which ship with windows, have the display by the bootloader, and efifb (yah!). But unlike x86 laptops, device power management isn't handled via ACPI[1]. Currently the CCF and genpd frameworks will turn off power domains and clocks that they think are unused. This is rather unfortunate, as it kills efifb scanout before getting to userspace and getting to the point where we can try to probe the real display driver. Also it has a few side-effects in that we can't set rate on running clocks (in many cases). The first two patches let us flag clocks and power domains which might have been enabled by the bootloader, so we know not to disable them in late_initcall. The next two update drm/msm to cleanly shut down clocks which might already be running. *Eventually* we'll want to detect that scanout is already running, and readback the hw state, to avoid briefly disabling the screen while the driver loads. But that is a big pile of (mostly) drm/msm work. (Windows also seems to have this problem, it appears to do a modeset during boot.. so I guess the first step is to at least not suck more than windows ;-)) The last patch updates the bridge driver to handle the case where display is already active. (AFAICT it is the same bridge chip used so far on all the aarch64 laptops.) Because the bridge driver can be probed before the drm driver, and in fact you might end up with a bridge driver but no drm driver, care must be taken to not disable the bridge until the drm driver is ready to go, so: * Request enable gpio ASIS to avoid pulling down the enable gpio * Defer enabling runpm in the case that the bridge is already running until bridge->attach(). This is a point where we know the drm driver is ready to do a modeset. (There are a couple related cleanups in drm/msm to avoid touching the hw until we are past the point where we might -EPROBE_DEFER[2] which I sent seperately as they are probably interesting to fewer people.) This has been tested on a lenovo yoga c630. I've a wip/c630 branch[3] with this and various other work-in-progress stuff for this laptop. Next step, figuring out how to pick the proper panel driver, from the two or three possibilites that ship on this laptop ;-) [1] On windows, they use a "Platform Extension Plugin" (PEP) driver [2] https://patchwork.freedesktop.org/series/62999/ [3] https://github.com/freedreno/kernel-msm/commits/wip/c630 Rob Clark (5): clk: inherit clocks enabled by bootloader genpd/gdsc: inherit display powerdomain from bootloader drm/msm/dsi: split clk rate setting and enable drm/msm/dsi: get the clocks into OFF state at init drm/bridge: ti-sn65dsi86: support booloader enabled display drivers/base/power/domain.c | 10 ++++ drivers/clk/clk.c | 48 +++++++++++++++++++ drivers/clk/qcom/common.c | 25 ++++++++++ drivers/clk/qcom/dispcc-sdm845.c | 24 +++++----- drivers/clk/qcom/gcc-sdm845.c | 3 +- drivers/clk/qcom/gdsc.c | 5 ++ drivers/clk/qcom/gdsc.h | 1 + drivers/gpu/drm/bridge/ti-sn65dsi86.c | 12 ++++- drivers/gpu/drm/msm/dsi/dsi.h | 2 + drivers/gpu/drm/msm/dsi/dsi_cfg.c | 3 ++ drivers/gpu/drm/msm/dsi/dsi_cfg.h | 1 + drivers/gpu/drm/msm/dsi/dsi_host.c | 56 +++++++++++++++++----- drivers/gpu/drm/msm/dsi/pll/dsi_pll_10nm.c | 1 + include/linux/clk-provider.h | 10 ++++ include/linux/pm_domain.h | 4 ++ 15 files changed, 178 insertions(+), 27 deletions(-) -- 2.20.1

laptop status and tasks: WW25

by Richard Henwood

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.
