This is a generic package for devices which use x86_64 CPU and 32-bit
EFI. Most distributions don't provide installation for 32-bit EFI, so
installation is not user-friendly.
Actually, these tablets deserve device-specific packages (I am going to
make ones for ASUS VivoTab Note 8 and ASUS Transformer Book T100TA), but
this one includes basic functions and can be booted on any 32-bit EFI
tablet with disabled secure boot and missing device-specific package.
I guess 32-bit EFI with 64-bit CPU is Intel's "feature" and AMD doesn't
have such stuff, so this package will be installed only on devices with
Intel CPU, unlike device-tablet-x64uefi which can be installed on any
x86_64 PC. So i decided to enable some Intel specific things (userspace
GPU stuff and alsa-ucm-conf).
I used for reference device-tablet-x64uefi and
device-trekstor-surftabduow1 packages. This package also can be used as
a reference for device-specific ones.
Added support for Motorola Moto E 2014 codename: condor
It is booting, has usb, battery, flashing needs special fastboot command for the boot partition
Port based on an unofficial LineageOS port
from https://www.los-legacy.de/17.1/zerofltexx, using kernel from https://github.com/Exynos7420/android_kernel_samsung_exynos7420/
What works:
- Kernel boots
- Display and touch input (tested with Weston)
- USB networking
Note: I removed camera support in kernel config for now, as there were related kernel crashes.
Wifi doesn't work either yet because the firmware dependencies/paths need to be fixed first.
The modprobe.conf is not necessary on those devices because they already
load the panel module using deviceinfo_modules_initfs. Let's skip the
modprobe.conf in that case so we don't need to add all panels in two places.
Simply disabling FIMC IS does not work however due to compilation
errors and a null pointer dereference. 01-fix-FIMC-IS-disabling.patch
takes care of this.
As with other exynos devices some additional things had to be disabled
to make the kernel compile after FIMC IS had been disabled,
specifically:
CONFIG_CAMERA_EEPROM
CONFIG_VIDEO_EXYNOS_MIPI_CSIS
CONFIG_LEDS_MAX77803
Apart from that we also have:
02-netfilter-symbols.patch, which fixes another compilation error.
03-usb_gadget-set-random-rndis-host-MAC-address-to-prev.patch (taken
from another device) which prevents host mac address being set to
00:00:00:00:00.
Kernel sources have been changed to the lineage-16.0 branch in the
exynos5420 repo, as that is where development happens at the moment.
based off from lineage os, manages to boot including ssh over usb.
had to disable:
CONFIG_HTC_RADIO_SMEM
CONFIG_HTC_MODEM_NOTIFIER
CONFIG_MSM_SMP2P
CONFIG_UIO_MSM_SHAREDMEM
[ci:skip-build]: already built successfully in CI
Instead of running the entire setup_usb_network_configfs function we
run the parts that are actually necessary for
setup_usb_network_android to succeed when it is run afterwards.
USB networking, Touchscreen and display are working.
CONFIG_SND_SOC_QDSP6V2 is omitted from kernel config for now as the resulting driver fails to build.
Changes:
- Depends on soc-sprd-audio-sc8830 package for audio support
- Includes fixes for X11 and color mode
- Switches to dtbtool-sprd
[ci:skip-build] Already built fine on CI in a MR
