[PATCH 0/4] drm+dt+efi: support devices with multiple possible panels

by Rob Clark

From: Rob Clark <robdclark(a)chromium.org> Now that we can deal gracefully with bootloader (firmware) initialized display on aarch64 laptops[1], the next step is to deal with the fact that the same model of laptop can have one of multiple different panels. (For the yoga c630 that I have, I know of at least two possible panels, there might be a third.) This is actually a scenario that comes up frequently in phones and tablets as well, so it is useful to have an upstream solution for this. The basic idea is to add a 'panel-id' property in dt chosen node, and use that to pick the endpoint we look at when loading the panel driver, e.g. / { chosen { panel-id = <0xc4>; }; ivo_panel { compatible = "ivo,m133nwf4-r0"; power-supply = <&vlcm_3v3>; no-hpd; ports { port { ivo_panel_in_edp: endpoint { remote-endpoint = <&sn65dsi86_out_ivo>; }; }; }; }; boe_panel { compatible = "boe,nv133fhm-n61"; power-supply = <&vlcm_3v3>; no-hpd; ports { port { boe_panel_in_edp: endpoint { remote-endpoint = <&sn65dsi86_out_boe>; }; }; }; }; sn65dsi86: bridge@2c { compatible = "ti,sn65dsi86"; ... ports { #address-cells = <1>; #size-cells = <0>; ... port@1 { #address-cells = <1>; #size-cells = <0>; reg = <1>; endpoint@c4 { reg = <0xc4>; remote-endpoint = <&boe_panel_in_edp>; }; endpoint@c5 { reg = <0xc5>; remote-endpoint = <&ivo_panel_in_edp>; }; }; }; } }; Note that the panel-id is potentially a sparse-int. The values I've seen so far on aarch64 laptops are: * 0xc2 * 0xc3 * 0xc4 * 0xc5 * 0x8011 * 0x8012 * 0x8055 * 0x8056 At least on snapdragon aarch64 laptops, they can be any u32 value. However, on these laptops, the bootloader/firmware is not populating the chosen node, but instead providing an "UEFIDisplayInfo" variable, which contains the panel id. Unfortunately EFI variables are only available before ExitBootServices, so the second patch checks for this variable before EBS and populates the /chosen/panel-id variable.

[PATCH 0/5] DtbLoader: panel-id and dtb picking support

by Rob Clark

This patchset builds on top of Leif's DtbLoader, adding support to pick a laptop specific dtb based on SMBIOS tables, and patching for /chosen/panel-id based on UEFIDisplayInfo. I'll send a new version of the kernel side patchset that uses /chosen/panel-id to pick the appropriate panel driver in the near future (ie. I'll probably get to it tomorrow) Rob Clark (5): DtbLoader: refactor out helper to try loading dtb DtbLoader: Try to pick dtb based on SMBIOS tables DtbLoader: move CRC calculation DtbLoader: resize fdt DtbLoader: add panel-id detection/fixup for qcom devices .../Application/ConfigTableLoader/Common.h | 2 + .../Application/ConfigTableLoader/DtbLoader.c | 437 +++++++++++++++--- .../ConfigTableLoader/DtbLoader.inf | 2 + .../Application/ConfigTableLoader/Qcom.c | 94 ++++ .../Application/ConfigTableLoader/Qcom.h | 30 ++ 5 files changed, 506 insertions(+), 59 deletions(-) create mode 100644 EmbeddedPkg/Application/ConfigTableLoader/Qcom.c create mode 100644 EmbeddedPkg/Application/ConfigTableLoader/Qcom.h -- 2.23.0

Adding devicetree command to grub

by Jeffrey Hugo

I'm curious, how have folks been adding the devicetree command to the grub menu entry? So far I've been manually editing the grub.cfg since that worked well with my development flow, but now things have changed a bit for me, and I'm looking for a way that it would be appended automatically when the config is autogenerated when installing a new kernel. -Jeff

is anyone running Debian?

by Richard Henwood

hi All, Is anyone running Debian user-space on a Yoga C630 or similar machine? I am interested in understanding how you got it to work and if you have written about your experience anywhere. best regards, Richard -- Richard.Henwood(a)arm.com Server Software Eco-System IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.

Yoga c630 won't boot from "enabled installer"

by David

I was able to get the Lenovo C630 to boot from the flash drive and have the trackpad work. Awesome! I'm now thinking the build looks good enough to install on the UFS drive. I tried the "enabled installer". I've updated WIndows. There are no pending updates. I've shrunk the partiion. I"m not running S mode I've disabled secure boot. I used Dimitri's Bionic installer. md5sum bde45aa67f19333955d00349aa6b2077 I flashed the installer onto a USB stick using gnome-disks WIth the flash drive in the left USB-C port, it boots straight to Windows. This is the same machine that was booting successfully from the flash drive into Linux. Any ideas? Is there a way to copy the flash drive image that does work onto the UFS drive? Thanks

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.
