PSI provides a canonical way to see resource pressure increases as
they develop, with pressure metrics for three major resources:
memory, CPU, and IO. PSI stats are like barometers that provide
fair warning of impending resource shortages, enabling users to
take more proactive, granular, and nuanced steps when resources
start becoming scarce.

This commit adds OpenWrt U-Boot layout support for Routerich AX3000. The
aims:
1. Get open-source U-Boot;
2. Get maximum available free space in OpenWrt.
Install
-------
1. Copy OpenWrt ubootmod-bl31-uboot.fip, ubootmod-preloader.bin, to the
/tmp folder of the router using scp.
2. Make mtd partitions backups:
http://192.168.1.1/cgi-bin/luci/admin/system/flash -> Save mtdblock
contents
3. Install kmod-mtd-rw:
```
opkg update && opkg install kmod-mtd-rw
```
4. Write FIP and preloader:
```
insmod mtd-rw i_want_a_brick=1
mtd unlock BL2
mtd erase BL2
mtd write /tmp/ubootmod-preloader.bin BL2
mtd unlock FIP
mtd erase FIP
mtd write /tmp/ubootmod-bl31-uboot.fip FIP
```
5. Copy OpenWrt ubootmod-initramfs-recovery.itb to the tftp server root
with IP 192.168.1.254.
6. Reboot router:
```
reboot
```
U-Boot will automatically download from the tftp server and boot OpenWrt
initramfs system.
7. Copy OpenWrt ubootmod-squashfs-sysupgrade.itb to the /tmp dir of the
router using scp.
8. Run sysupgrade:
```
sysupgrade -n /tmp/squashfs-sysupgrade.itb
```
Recovery
--------
1. Place OpenWrt initramfs-recovery.itb image (with original name) on the
tftp server (IP: 192.168.1.254).
2. Press "reset" button and power on the router. After ~10 sec release the
button.
3. Use OpenWrt initramfs system for recovery.
BL2 and FIP recovery
--------------------
Use mtk_uartboot and UART connection if BL2 or FIP in UBI is destroyed:
Link: https://github.com/981213/mtk_uartboot
Return to stock:
----------------
1. Copy partition backups (BL2.bin and FIP.bin) to the /tmp dir of the
router using scp.
2. Install kmod-mtd-rw:
```
opkg update && opkg install kmod-mtd-rw
```
3. Restore stock U-Boot and reboot:
```
insmod mtd-rw i_want_a_brick=1
mtd unlock BL2
mtd erase BL2
mtd write /tmp/BL2.bin BL2
mtd unlock FIP
mtd erase FIP
mtd write /tmp/FIP.bin FIP
reboot
```
4. Open U-Boot web recovery, upload stock firmware image and start
upgrade.

Deactivate CONFIG_CONTEXT_TRACKING_USER_FORCE: Force user context
tracking: This is a testing feature which should not be activate in
production environments according to the Kconfig help. It adds an extra
overhead.
Deactivate CONFIG_RCU_NOCB_CPU_DEFAULT_ALL: Offload RCU callback
processing from all CPUs by default: This option should only be used in
aggressive HPC or real-time workloads which we do not have in OpenWrt.
For normal workloads it increases the number of context switches.
In the default Arch Linux kernel both options are not activated.

This commit adds support for two variants of the already supported router
Acer Predator Connect W6: The Acer Predator Connect W6d (W6 without 6 GHz
wifi) and the Acer Connect Vero W6m (W6 without 2.5G eth1 port, usb3 port,
and the 6 on-board gpio RGB LEDs, and with a KTD2026 RGB LED controller
instead of the KTD2061 LED controller of the W6/W6d).
The device tree for the W6m refers to the KTD202x driver suggested in
PR #16860.
Patching target/linux/mediatek/filogic/base-files/lib/upgrade/platform.sh
removes the code repetition in (old) lines 121 to 124 on the occasion.

In order to prepare for OpenWrt support other Acer W6 devices and to get
a step further to full hardware support for Acer Predator Connect W6, this
commit
- adjusts the product name ("Acer Predator Connect W6")
- updates gpio LED labels to function/color scheme
- show router status by using first rgb led instead of it's red color only
(blue: booting/failsafe mode; red: sysupgrade; green: running – was: red)
- changes switch/eth1 led configuration to reflect RX/TX activity and speed
(green: full 1Gbps/2.5Gbps speed; amber: lower speed; blink: RX/TX)
- shortens dummy dm-mod.create string in bootargs
- enables W6's i2c interface

In order to prepare OpenWrt support for other Acer W6 devices and to adapt
the procedure to read and set mac addresses which other devices of the same
target are using (instead of needing an additional script and creating an
additional structure in the file system), this commit
- reads device mac addresses from u-boot environment
- avoids the detour via the file system to set the mac addresses
- drops redundant file /lib/preinit/05_extract_factory_data.sh
The idea and the implementation were thankfully taken from PR #16410.

In order to prepare OpenWrt support for other Acer W6 devices, this commit
moves all device tree components that are used by all Acer W6/W6e/W6d/W6m
routers from mt7986a-acer-predator-w6.dts to mt7986a-acer-w6-common.dtsi
(new file) and includes this dtsi file in mt7986a-acer-predator-w6.dts.
Minor changes had to be made to the device tree in order to improve clarity
and – notably – to reduce the number of dtc warnings:
- replace (obviously wrong) led@<N> gpio led entities by led-<N>
- remove unnecessary (default-state = "off") gpio led statements
- rename entity “memory” to “memory@0”
- add missing #address-cells and #address-size in /soc/mmc@11230000
- add missing #address-cells and #address-size in /soc/pcie@11280000
- introduce symbols “nvmem” and “swport0” in dtsi (referenced in dts)
The changes were checked with `diff -BEZbdtwy --suppress-common-lines ...`
(comparing two dts files created using old and new fdt-1 blobs again), see

Popular bpi-r3 pwm fans like this one
https://www.amazon.com/youyeetoo-Barebone-Fan-BPI-R3-Integrated/dp/B0CCCTY8PS
will not work properly with current openwrt-23.05/24.10 firmware.
Trying different pwm setting
echo $value > /sys/devices/platform/pwm-fan/hwmon/hwmon1/pwm1
I found:
pwm1 value fan rotation speed cpu temperature notes
-----------------------------------------------------------------
0 maximal 31.5 Celsius too noisy
40 optimal 35.2 Celsius no noise hearable
95 minimal
above 95 does not rotate 55.5 Celsius
-----------------------------------------------------------------
At the moment we have following cooling levels:
cooling-levels = <255 96 0>;
for cpu-active-high, cpu-active-medium and cpu-active-low modes correspondingly.
Thus only cpu-active-high and cpu-active-low are usable. I think this is wrong.
This patch fixes cpu-active-medium settings for bpi-r3 board.
PS: I know, the patch is not ideal as it can break pwm fan for some users.
There are some peoples that use handmade cooling solutions, but:
* discussed cooler is the only 'official' pwm cooler for bpi-r3
available on the market.
* most peoples will use passive cooling available on the market or
the discussed cooler.
* the pwm-fan dts section was added before the official cooler
appears on the market.
Thus it should not be a lot of harm from this fix.

Note that the old ad-hoc method did not explicitly align backup data
to 64 KiB boundaries.
Also note that the qnap 301w has a 'rootfs_data' partition in the eMMC
that is being ignored by fstools during boot, presumably due to a bug.
This is why the partition is also ignored in the sysupgrade code and
there is no definition of CI_DATAPART="rootfs_data".

This commit fixes and closes#16313.
Switch the x86 kernel's timer to tickless operation which is
more power efficient since it is not woken up by periodic timer
interrupts when idle. Also add several other options for CPU
idle governors particularly the upstream default for tickless
kernels, CONFIG_CPU_IDLE_GOV_MENU. Without this commit, my AMD
Ryzen 7 5800U can only achieve a minimum core frequency of 1,384
MHz which is over 3x higher than the processor's minimum
frequency of 400 MHz which is accessible with this modification.
In addition to the lower clock rate, I have seen a concomitant
reduction in both idle temps and at-the-wall power consumption.
Summary:
* Idle CPU freqs dropped from 1,384 MHz to 400 Mhz.
* Idle power consumption dropped from 7 W avg to 5 W.
* Idle temps have dropped from 50C on avg to 43C.
There are other well known reasons to switch to a tickless
timer including: reduced interrupt overhead, better use of CPU
resources, and reduced latency to name a few.

The GatoNetworks GDSP is a re-branded version of the R5000 5G Industrial
router from Yinghua Technologies.
The re-branded device comes with OpenWrt preinstalled, and an OpenWrt-based
U-Boot bootloader version. While the flash layout has been kept compatible
with the OpenWrt version found on the stock device (see [5]), the image format
changed, making a bootloader upgrade necessary.
Specifications:
SoC: Mediatek MT7981BA
RAM: 256MB
Flash: SPI-NOR 32 MiB (Winbond W25Q256)
WLAN: MT7976CN DBDC AX Wi-Fi
Switch: MT7531AE (4x LAN Gigabit ports, 1x WAN Gigabit port)
5G: Quectel RM520N modem
Watchdog: an external WDT connected to GPIO 6 is present and always running;
the built-in Mediatek watchdog is also present and effective, but
not used at the moment.
This porting has been tested only with 1x 5G modems installed (the device
supports up to two).
Installation:
Installation is possible via sysupgrade both in the stock device and
re-branded version. However, in the former case, updating the bootloader is
required.
OpenWrt-based U-Boot Bootloader installation
--------------------------------------------
The firmware flashed in the re-branded device at manifacturing time will
flash an OpenWrt-based U-Boot bootloader with some extra recovery features
(see [1]) at first boot.
To update the bootloader, you need to install the mtd-rw module and
insmod it:
insmod mtd-rw i_want_a_brick=1
Then update relevant flash partitions:
mtd erase u-boot-env
mtd erase BL2
mtd erase FIP
mtd write openwrt-mediatek-filogic-gatonetworks_gdsp-preloader.bin BL2
mtd write openwrt-mediatek-filogic-gatonetworks_gdsp-bl31-uboot.fip FIP
And reboot, making sure all previous commands ran succesfully.
If something goes wrong, you can recover your device via the mtk_uartboot
tool.
In my testing, it was possible to start the process even without (un)-plugging
the device, may be handy for remote recovery.
Installation from stock device and firmware
-------------------------------------------
To install vanilla OpenWrt in the stock device (R5000 5G Industrial router
from Yinghua Technologies) running the stock vendor firmware, you will need
to update your bootloader as described in previous section. Remember to use
-F (force upgrade) and -n (not keeping settings).
U-Boot Recovery
---------------
This procedure has been tested only with the OpenWrt-based U-boot bootloader.
Assign your system static IP address 192.168.1.1 and start a TFTP server. The
device will look for an initramfs image named
openwrt-mediatek-filogic-gatonetworks_gdsp-initramfs-kernel.bin
(so you may use openwrt/bin/targets/mediatek/filogic as root dir for your
TFTP server).
Power on the device while keeping the reset button pressed, until you see
a TFTP request from 192.168.1.10. Your environment will be restored to it's
default state.
MAC addresses assignment
------------------------
MAC addresses are assigned slightly differently than in stock firmware. In
particular, the 5 GHz Wi-Fi uses 2.4 GHZ MAC + 1, rather than reusing it with
LA bit set as done in stock firmware. This MAC address is allocated to the
device, so it can be used.
The 2.4 GHz Wi-Fi MAC address is the label MAC. LAN MAC is used to set the
special U-Boot environment ethaddr variable.
device MAC address U-Boot env variable factory partition offset
2.4 GHz Wi-Fi :84 wifi_mac 0x4
5.8 GHz Wi-Fi :85 not present not present
WAN :86 wan_mac 0x24
LAN :87 lan_mac 0x2A
Notes
-----
[1]: the OpenWrt-based U-Boot bootloader you will find installed in the
re-branded device is configured to request for the initramfs image via
TFTP for $gdsp_tftp_tries times before trying normal boot from NOR flash.
Setting this U-Boot environment variable to 0x0 will disable the feature,
which is not implemented in this patch.
[2]: the exposed UART port is connected to ttyS1; the ttyS0 console port is
not exposed.
[3]: the provided bootloader environment has no provision for operating on
BL2 and the FIP partitions. This is an intentional choice to make it
(slightly) more difficult to brick the device.
[4]: it seems GPIO 6 is used both for the "SYS" LED and external WDT.
[5] BL2 expects to find FIP payload at a fixed offset, so some constraints
apply.

i2c_add_numbered_adapter is the wrong function to use here. It requires
setting nr to some value, otherwise it behaves the same as
i2c_add_adapter. nr is not set.

What seems to be happening is that the kernel requests an ACTIVE_LOW
gpio initially and sets it to high later based on gpios in dts.
This seems to break some devices where the bootloader sets it to high.

Edgerouter-X factory images have not built automatically since 19.x due
to images being over 3MB. While it was possible to build custom images
with very stripped down config, this is no longer possible with the size
increases of linux 6.1 and 6.6.
Drop code for generation of factory images, if some dev later wishes to
try custom images they can revert this commit.

With the new layout providing 6MB for kernel there will be no issues
with kernel size affecting build of images.
Re-enable image builds for Edgerouter-X and X-SFP.

Use compat version to indicate that the new layout for larger kernels
is in place. This handled by the patch to ubnt.sh to always select
the kernel1 slot for flashing and as active kernel slot.
