set your desired write/caching parameters via proc/sysfs then dd to tmp/test.img with the correct options ( no buffering ).
If you check the other post I put some output as I ported the fab scaler to 4.19 by using mbw
I'm asking for a way to check real improvement.
Cannot find that other post....
Why do not you setup SQM with cake and compare the results? That is probably the most CPU and memory intensive “router” function.

Not enough band to test it
This is the other post

Yeah, unless you have a spare PC/router to test locally, I am not sure how else to test real life improvements...
@hnyman i'm doing some test with my r7800... I'm trying to use the ramfs image
I selected it with menuconfig but i can't find a way to make it working...
I tried use the tftpboot feature of uboot but with the command go 0x4200000 the router crash and reboot
Can you tell me how to do this?
Sorry, I have never used the ramfs image.
But it was recently mentioned in
And it referenced to R7800 initramfs instructions at
But I have not tested that.
the ram boot address is device dependent. i.e. it is different on my r7500v2 (44000000) compared to the r7800 (50000000 in @quarky's instructions)
as described in step 8 of my instructions for the r7500v2 here, try
printenv
and look for the "bootcmd" environment variable. Using the loadaddr environment variable "0x42000000" did not work for me either (I think this is the nand address to load an image from).
so you are telling me tftpboot load the image not in ram but in the nand o.O... good work netgear REALLY.
(Anyway just as a info... i'm working on updating the cpufreq patch that is 6 years old... from 2014... latest revision, 12 got included in mainline kernel and applies correctly... the last 2 patch got dropped for some reason and we actually don't have cpufreq with opp on ipq8064 platform... I have updated the driver and the dtsi but I need to find the reason the driver stalls on driver load)
(this will remove like 14 patch and mark them as backported as they are applied upstream, making the switch to 5.4 easier)
i wish i had serial :(. i think @anon50098793 was working on being able to boot off a USB image (without serial) at one point, but he needed testers with serial.

it would help alot if anyone can paste a full printenv / fw_printenv in this thread ( one for each device type )
( minus anything erroneous like macs or misc fields )
static commands to "usbload" on your systems too it would also help...
i.e.
kload=0x44000000
uload=0x50000000 #< safe address to load a uEnv.txt non-oem
sload=0x49000000 #< safe address to load scripts non-oem
oembootcmd=setenv syno_extra_args syno_rescue=1; run syno_bootargs; ext2load mmc 0:3 $kload zImage;ext2load mmc 0:3 $rload rd.bin;bootipq
wrtgo=usb start; ext2load usb 0:1 $kload kernel; run wrtbootarg; bootm $kload
A serial USB cost like 12 euros
Anyway I will post here my changes but still no success... All works good on the router but for some reason it doesn't register the opp (so no cpufreq)
Any idea?
serial console requires hardware mods to the R7800 though doesn't it?
No, it does not.
The serial headers pin is already flashed... You just need to open it
Just open the cover and attach the serial cable to pins, like I describe in the message 2 of this thread...
yeah, i don't want to pry it open :).
Opening five screws is no "hardware mod"...
