> tl,dr: add 4 small-ish UEFI-like kernels, with Microsoft patches & fixes, for use with Microsoft WSL2 on x86/arm64 and 6.1.y/6.6.y
- the boards are UEFI derivatives, using a common `microsoft` vendor include to modify
- `KERNELPATCHDIR`/`LINUXFAMILY` (for now, we don't want those patches in regular UEFI builds / .debs)
- disable `EXTRAWIFI` (kernel is for a VM, will never have wifi so doesn't need any drivers)
- `LINUXCONFIG`, so we can use Microsoft's own monolithic kernel, required for WSL2 (their initrd is a mistery)
- really, what we're mostly interested right now are the kernels (in the future we might have an "Armbian" WSL2 app in the Microsoft Store)
- `current` `6.1.y`:
- rebased from https://github.com/microsoft/WSL2-Linux-Kernel/tree/linux-msft-wsl-6.1.y onto real 6.1.y
- using Microsoft's `.config` exactly (monolithic, there are no `=m`'s)
- `edge` `6.6.y`:
- also from https://github.com/microsoft/WSL2-Linux-Kernel/tree/linux-msft-wsl-6.1.y but rebased onto 6.6.y
- using updated Microsoft's `.config` (monolithic, there are no `=m`'s)
- dropped 2 of 6.1.y's patches that were actually upstreamed in the meantime:
- `mm-page_reporting-Add-checks-for-page_reporting_order-param` - mainlined in https://lore.kernel.org/all/1664517699-1085-2-git-send-email-shradhagupta@linux.microsoft.com/
- `hv_balloon-Add-support-for-configurable-order-free-page-reporting` - mainlined in https://lore.kernel.org/all/1664517699-1085-3-git-send-email-shradhagupta@linux.microsoft.com/
- drop the `arm64: hyperv: Enable Hyper-V synthetic clocks/timers` patch, since it causes asm breakage on 6.6.y
- a shame, but I tried and can't fix it myself - @kelleymh ?
- add my own patch to fix:
- `1709-drivers-hv-dxgkrnl-restore-uuid_le_cmp-removed-from-upstream-in-f5b3c341a.patch` due to https://lore.kernel.org/all/20230202145412.87569-1-andriy.shevchenko@linux.intel.com/ landing in 6.6
- `1710-drivers-hv-dxgkrnl-adapt-dxg_remove_vmbus-to-96ec29396-s-reality-void-return.patch` to adapt to
https://lore.kernel.org/all/TYCP286MB2323A93C55526E4DF239D3ACCAFA9@TYCP286MB2323.JPNP286.PROD.OUTLOOK.COM/
I have changed the way the patches are generated a bit. Instead of using orange-pi branch from megous tree for 6.6 kernel, I have used the following kernel branches
a83t-suspend, af8133j, anx, audio,
axp, cam, drm, err, fixes, mbus,
modem, opi3, pb, pinetab, pp, ppkb,
samuel, speed, tbs-a711, ths
These branches were carefully chosen to include only allwinner related patches and remove importing of the rockchip related patches into the allwinner kernel.
Following patches are modified to fix patch application failure
- patches.armbian/arm64-dts-sun50i-h616-orangepi-zero2-reg_usb1_vbus-status-ok.patch
- patches.armbian/arm64-dts-sun50i-h616-orangepi-zero2-Enable-GPU-mali.patch
- patches.armbian/arm64-dts-allwinner-h616-Add-efuse_xlate-cpu-frequency-scaling-v1_6_2.patch
- patches.armbian/arm64-dts-allwinner-h616-LED-green_power_on-red_status_heartbeat.patch
- patches.armbian/arm64-dts-allwinner-overlay-Add-Overlays-for-sunxi64.patch
- patches.armbian/arm64-dts-sun50i-h616-bigtreetech-cb1.patch
Following patches are modified because of kernel api change to fix compilation failure
- patches.armbian/drv-gpu-drm-sun4i-Add-HDMI-audio-sun4i-hdmi-encoder.patch
- patches.armbian/drv-of-Device-Tree-Overlay-ConfigFS-interface.patch
Set fan max speed to kick in at 65*C. This keeps the unit roughly
at 70*C or lower, when pusing all cores for an extended period of
time.

Fan, RTC and USB support
RTC requires rtc pcf85063 driver
Fan requires hwmon emc2305 driver
Added wakeup-source to fanctrl node so emc2305 module loads at boot.
