Help needed: We want to improve performance on exotic boards

Question

Dear all,

 

we need some help from Banana Pi M2 (not that important), Cubox-i/UDOO and ODROID XU4 users.

 

Please look through this Github issue and also have look how we currently handle IRQ redistribution on various board families (example 1 and example 2)

 

Since irqbalanced on ARM is broken (and if it would work it's often counterproductive) assigning IRQs statically to specific CPU cores increases overall system performance slightly for free. We do this for A20 boards for years (dual core --> sending Ethernet to second CPU core), extended this on H3 boards a few months ago (quad core and somewhat complicated due to the count of different boards exposing different interfaces) and added other board families just recently.

 

Now we need you!

 

In case you are somewhat experienced please get back to us with the output of

cat /proc/interrupts

(when you're running a more recent Armbian version then output of 'sudo armbianmonitor -u' is preferred!)

 

And in case you're able to do some testing please have a look at the examples above and the Github issue (Amlogic kernels seem to need different procfs calls for example), test yourself and provide code snippets already known to work!

 

Thx in advance!

sudo armbianmonitor -u is not very useful http://sprunge.us/WYTL

(note: I am managing XU4 fan PWM myself so it outputs a lots of logs)

sudo armbianmonitor -u is not very useful http://sprunge.us/WYTL

 

Hmm... can you please replace the contents of /usr/local/bin/armbianmonitor with https://github.com/igorpecovnik/lib/blob/master/scripts/armbianmonitor/armbianmonitor then run the following code (and report back if error messages appear), generate some activity and try again?

echo 2 >/proc/irq/$(awk -F":" "/usb2/ {print \$1}" </proc/interrupts | sed 's/\ //g')/smp_affinity
echo 4 >/proc/irq/$(awk -F":" "/usb3/ {print \$1}" </proc/interrupts | sed 's/\ //g')/smp_affinity
echo 8 >/proc/irq/$(awk -F":" "/usb5/ {print \$1}" </proc/interrupts | sed 's/\ //g')/smp_affinity
echo 16 >/proc/irq/$(awk -F":" "/dw-mci/ {print \$1}" </proc/interrupts | sed 's/\ //g' | tail -1)/smp_affinity
echo 32 >/proc/irq/$(awk -F":" "/dw-mci/ {print \$1}" </proc/interrupts | sed 's/\ //g' | head -1)/smp_affinity
for i in $(awk -F':' '/11800000.mali/{print $1}' /proc/interrupts); do
	echo 64 >/proc/irq/$i/smp_affinity
done

(does the XU4 have no Ethernet? Or is this USB?!)

 

EDIT: It's Realtek 8153 USB3 chipset.

@Tk,

 

the issue with "armbianmonitor -u" when dmesg is too large you only get dmesg in the log

so I have rebooted & it is better

http://sprunge.us/jTFh

 

note: need to add activity

gr@odroidxu4:~$ sudo ./tkActivityTest
gr@odroidxu4:~$ sudo armbianmonitor -u
/var/log/armhwinfo.log has been uploaded to http://sprunge.us/hNgL

http://sprunge.us/hNgL

 

 

note: I have badly named your script : tkActivityTest => tkChangeIRQCPUaffinity

 

I have done HDD reading (cloudshell NAS uses USB3=>SATA), reading from /dev/TrueRNG (on USB3 port #2), find / for MMC

(no USB2, no Mali)

Would be great if you can replace the contents of /etc/init.d/armhwinfo with latest version from Github, then add the IRQ redirection stuff to the XU4 case construct, restart and report back after some activity.

 

And if you've some spare time maybe investigating what's wrong with the dmesg call in armbianmonitor's line 666 ;) -- maybe playing around with '-s, --buffer-size' option helps?

updated armhwinfo, added the IRQ redirection in /etc/rc.local and rebooted

part 2/

 

Let's see what I can do with "dmesg"

 

I guess line 666 of armbianmonitor is not cursed

I had an old version of the script and I guess Igor too

 

up-to-date "armbianmonitor -u" is working

Banana Pi M2

PS: I don't use the latest Armbian toolchain.

 

Doesn't matter since it's just about testing out IRQ redistribution. Could you please exchange the contents of /etc/init.d/armhwinfo with this here, reboot and try again (doing some stuff and then checking/posting /proc/interrupts)? Or simply try to execute the statements in the BPi M2 case manually, do some stuff and get back with results (just to ensure that the code works and does something useful since it would be great if we could starting with 5.15 do reasonable IRQ distribution on every board we support). Thx!

I did

- copy armhwinfo

- reboot

- copy some GB over NFS

Thx, seems to work but unfortunately when testing locally I made a mistake that went on pastebin.com too:

		sun6i) # Banana Pi M2: do network on cpu1, SDIO on cpu2, USB on cpu3
			for i in $(awk -F':' '/eth0|brcmf_oob_intr/{print $1}' /proc/interrupts); do
				echo 2 >/proc/irq/$i/smp_affinity
			done
			for i in $(awk -F':' '/sunxi-mmc/{print $1}' lala.txt); do
				echo 4 >/proc/irq/$i/smp_affinity
			done
			for i in $(awk -F':' '/hcd:usb/{print $1}' lala.txt); do
				echo 8 >/proc/irq/$i/smp_affinity
			done
			;;

lala.txt should be replaced with /proc/interrupts then USB and SDIO IRQs should be handled by 3rd and 4th CPU core :)

/proc/interrupts or </proc/interrupts?

if </proc/interrupts, what about line 232?

 

Doesn't really matter since awk either uses stdin or the file argument. Since it works (eth0 on cpu1) in your setup just with /proc/interrupts I would give this a try.

Ahh, I didn't mind the awk syntax.

But bash complains.

/etc/init.d/armhwinfo: line 233: echo: write error: Input/output error

 

Weird since eth0 has been sent successfully to cpu1 before? Can you please check state of /proc/interrupts now and maybe do the manual call again prefixing everything with

/bin/bash -x /etc/init.d/armhwinfo start

and upload the whole output on pastebin.com or similar? Thx!

Hmm, I tried the lala version, too, and that's the output:

I don't use postebin, etc. I could post the whole output here.

 

Here is a snippet:

Does armhwinfo do not exit?

Hmm... since the code does what it's supposed to (sending IRQ processing to dedicated CPU cores) I'll simply suffix all the calls with ' 2>/dev/null'. Thx for your help, new settings will then be active starting with Armbian 5.15 :)
