[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.

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

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.
