Add support for Allview Allbook Q

[paulstelian97]

Hello, I've just got a new Allview Allbook Q, which comes with Windows 10 Home. It doesn't seem to be among your supported laptops so I want to help out.

But first, what do I need to do to help? What should I provide, what should I test on my own etc.

SoC: Snapdragon 835 Internal storage: UFS (Universal Flash Storage) from Qualcomm. I assume already supported. iGPU: Adreno 540 Touchpad + keyboard: I2C HID device (ACPI\QCOM001F\6 for bus, ACPI\QTEC0001\3 for device)

Any other details, available on request (as long as you can tell me how to get them). I can run acpidump on this system as well (32-bit x86 executables work since it's regular Windows 10).

Welcome @paulstelian97 !

I suggest the first thing to do is follow the instructions for https://github.com/aarch64-laptops/build#booting-into-Ubuntu to disable secure boot and try booting the special Ubuntu 18.04 installer: https://pskov.surgut.co.uk/bionic/daily-live/current/ The install should boot up off a USB drive. NOTE: Some folks have observed sensitivities to drive size, physical port, and Windows firmware versions, you may need to try variations of drive, port etc.

If the installer comes up - that is good news. After that you can decide if you want to follow the instructions to create a dual-boot environment.

Please let us know how you get on :)

Dual boot won't be possible because internal eMMC is 64GB. Otherwise I'll try as soon as I can. Secure Boot is already off.

I only have one USB port that I can use (well, two if I can use my USB-C to USB-A adapter, but that means I cannot simultaneously have my laptop plugged in because the charging port is too close to the USB C port).

HP devicetree: I can boot and can use USB mouse. Builtin touchpad (I2C according to Windows' Device Manager) doesn't work. Also very slow and dmesg is full of errors. lspci is empty (no PCI buses). Wi-Fi card not detected. Battery not detected. Builtin sound not detected. xrandr "Failed to get size of gamma for output default" and claims 77Hz (which I think is false). USB works, of course.

I notice that the keyboard is supported because of an OF node (firmware/devicetree/base/soc/i2c@c17a000/keyboard@3a). Guess that one just lucked out or is there some standardization there?

Anyway, long way to go until everything works fine. But this looks like a starting point?

Trying the other device trees... will edit comment with extras.

I feel the BogoMIPS value is too low for a laptop performing about as well as my main one, did it really only test the weaker cores? (this SoC has big.LITTLE on it)

EDIT: Asus DT. Keyboard does NOT work on this one. Similarly slow. Forgot to do lscpu on this one. EDIT: Lenovo Mix DT. Keyboard works. Feels even slower than the already slow other ones. Detects 3.4GB of RAM (the other ones I didn't check). Laptop actually has a full 4 (though I'm unsure if it's actually fully usable). Spam detected in /dev/sd* (plenty, PLENTY of disks). I don't want to write in them no dice.

Dumping the disks themselves (other than the actual Windows disk, since that one is larger than my flash drive and I don't think contains anything relevant). Will attach the archive in a future edit. (EDIT: Here they are. The last one is 4GB but according to partition editors it's actually mostly empty https://www.dropbox.com/sh/xkipc54texepecw/AAAQPQzyGpUAunfpQCpezrXma?dl=0 )

The final DTB in the list doesn't work at all (the Lenovo Yoga one).

ACPI.zip ACPI tables, extracted from one of those weird disks (apparently the dd dumps might be corrupted or something)

QCOM.zip Some .PROVISION files. Not sure what they are used for but I think they may be necessary inside the DT? Removed MSDM.ACP (which I think contains my Windows 10 Home OEM serial key).

TZAPPS.zip No clue what this is but I found it so yeah.

I no longer own the device, so I'm closing this. If someone else has this device, feel free to reopen the issue.
