The service is only enabled by default on Vim4 as that board heats
a lot and a fan is absolutely necessary. Service will be available
on vim1s as well and if someone has purchased the fan for it, they
would be able to enable it themselves.
The service is only added for legacy kernel right now as I am not
sure if the upcoming 5.15 kernel will have same sysfs interface for
fan.
Khadas's 5.4 kernel has a broken hdmi subsystem that can result into
a monitor not working even if it supports one of the required display
resolution. Hence adding a workaround that will force use of one of
the 3 16x9 resolutions supporting most of the HD-ready, full-HD and
4K monitors.
- vim1s/vim4: remove uEnv.txt and default extlinux args, use simple arguments instead
- meson-s4t7.conf: hack: rereadpt (re-read partition table) in initrd local-top (for eMMC boot of oowow'ed image)
- meson-s4t7.conf: include both `u-boot.bin.sd.bin.signed` and `u-boot.bin.signed` in uboot package
- meson-s4t7: patch kernel for different dt "model" across VIM4 and "New VIM4"
- meson-s4t7.conf: set `EXTLINUX_SPECIFIC_FDT=no`, so u-boot auto-determines which DTB to use
- don't specify DTB; this way both the "original VIM4" and the "new VIM4" can boot with the same image
- only "boot from SD" supported right now
- building uboot with xPack riscv-none-embed-gcc **external** toolchain setup in hooks
- kvim4: very high kernel logging + systemd debug logging to console
- kvim4/kvim1s: add uEnv.txt and ROOT_FS_LABEL="ROOTFS" and Khadas-esque extlinux
- meson-s4t7: unify khadas-vim1s and khadas-vim4 u-boot building
- kernel .config:
- s4t7: original Khadas vendor config
- s4t7: CONFIG_BINFMT_MISC=y
- s4t7: make NFS/sunrpc stuff =y
- s4t7: enable USB wifi drivers from Armbian network_drivers
- firmware: at https://github.com/armbian/firmware/pull/56
- extlinux tricks require https://github.com/armbian/build/pull/5462
- status:
- kvim1s: boots from SD and works as server/CLI
- kvim4: kernel panic during systemd-udevd
