The installer has worked on all of the 5-6 laptops (from 2-3 different batches) I've worked on. Maybe there is something wrong with the way it was flashed. Have you tried mounting it on your development machine. What does it look like in `fdisk` and `gparted`? > On Wed, Sep 4, 2019 at 5:05 AM Lee Jones <lee.jones(a)linaro.org> wrote: > > > On Tue, 03 Sep 2019, David wrote: > > > > > I was able to get the Lenovo C630 to boot from the flash drive and have > > the > > > trackpad work.

[EOAN][UNSTABLE][PATCH] UBUNTU: SAUCE: arm64: dts: qcom: Add support for AArch64 laptops

by Dimitri John Ledkov

From: AArch64 Laptops <aarch64laptops(a)gmail.com> This is squashed merged of multiple patches from https://github.com/aarch64-laptops/linux/tree/laptops-ubuntu Note that some of these, with different names are getting upstreamed targetted for v5.4. Once those are all merged and available, this patch will become obsolete and will be dropped. This enables booting using flash-kernel in eoan on Lenovo Mixx 630 & Yoga C630, Asus TP370QL, HP Envy x2. Squashed commit messages below: arm64: dts: qcom: Add support for MSM8668 based laptops 3 files are being introduced to describe the differences between the newly released Snapdragon 835 (MSM8668) based AArch64 Laptops. There are 3 currently available: * ASUS NovaGo TP370QL * HP Envy x2ta * Lenovo Miix 630 The later two (HP and Lenovo) are very similar and are as yet able to share the same Device Tree Binaries. Once any difference arise, a new file 'laptop-lenovo-miix-360.dts' will have to be drafted. These files ensure the following work on each of the devices: * Touchpad * Keyboard * SDCHI SD card reader (card detect) arm64: config: laptops: Enable the RPM PM8998 regulators arm64: dts: qcom: Pull up trackpad IRQ on the Asus Stops IRQ storm and renders trackpad functional instead of laggy. arm64: dts: qcom: Provide Lenovo Mixx 630 with its own DTB arm64: dts: qcom: Add Lenovo Yoga C630 The Lenovo Yoga C630 is built on the SDM850 from Qualcomm, but this seem to be similar enough to the SDM845 that we can reuse the sdm845.dtsi. Supported by this patch is: keyboard, battery monitoring, UFS storage, USB host and Bluetooth. arm64: dts: qcom: Move HID device at 0x2C to its rightful place According to the ACPI tables the HID device at I2C address 0x2C should be located under the I2C Controller with address 0x88C000, presented as I2C3 in DT and I2C4 in ACPI.

[EOAN][UNSTABLE][PATCH 0/3] UBUNTU: SAUCE: Enable WMI on arm64

by Dimitri John Ledkov

These are cherrypicks from the aarch64-laptops [1] effort. I have pinged those maintainers pointing out that these patches have not been submitted upstream. In the future it should be... Otherwise, I'll keep rebasing this. This is useful on the AArch64 laptops [2] booting in ACPI mode, as they are Win10 laptops they use/publish WMI, hence it should stop being x86 only and be enabled on arm64 too.

Galaxy Book 2 support

by Joshua Lee

Hello, this appears to be a development-only mailing list, so pardon me if I’m disturbing anyone. I’m running a Samsung Galaxy Book 2 (using SD850 + QUALCOMM x20 modem + AMOLED touch screen, detachable KB, and stylus) and am wondering if the work being done mostly on Lenovo SD850 laptops apparently and older devices will apply to this hardware, or should I not hold my breath? Don’t worry, this isn’t an ETA or a complaint, I appreciate everything you’re doing and wish I knew more about programming so I could help out. Sent from Mail for Windows 10

blacklisting built-in and regular modules via cmdline instead of config

by Dimitri John Ledkov

So, we still have sensor-hub and acpi-button disabled using kernel config. I could patch the quirks into the kernel to skip loading those based on DMI data. However, that's a bit counter-productive as that's compiled in code and enumerates SKUs. Can I instead use kernel command line to skip initializing those built-in and compiled modules? Ie. would something like: module_blacklist=hid-sensor-hub initcall_blacklist=acpi_button_driver_init work, even when the kernel is configured with CONFIG_HID_SENSOR_HUB=m and CONFIG_ACPI_BUTTON=y ? Also not sure if I got the initcall function name right. I am asking because, it may be easier for me to control cmdline reliably, instead of distro kernel config. -- Regards, Dimitri.

[PATCH 0/2] iommu: handle drivers that manage iommu directly

by Rob Clark

From: Rob Clark <robdclark(a)chromium.org> One of the challenges we need to handle to enable the aarch64 laptops upstream is dealing with the fact that the bootloader enables the display and takes the corresponding SMMU context-bank out of BYPASS. Unfortunately, currently, the IOMMU framework attaches a DMA (or potentially an IDENTITY) domain before the driver is probed and has a chance to intervene and shutdown[1] scanout. Which makes things go horribly wrong. This also happens to solve a problem that is blocking us from supporting per-context pagetables on the GPU, due to domain that is attached before driver has a chance to attach it's own domain for the GPU. But since the driver is managing it's own iommu domains directly, and does not use dev->iommu_group->default_domain at all, the simple solution to both problems is to just avoid attaching that domain in the first place. [1] Eventually we want to be able to do a seemless transition from efifb to drm/msm... but first step is to get the core (iommu, clk, genpd) pieces in place, so a first step of disabling the display before first modeset enables us to get all of the dependencies outside of drm/msm in place. And this at least gets us parity with windows (which also appears to do a modeset between bootloader and HLSO). After that there is a bunch of drm/msm work that is probably not interesting to folks outside of dri-devel.

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

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

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.
