Tried "Armbian_22.08.0-trunk_Nezha_sid_current_5.19.0_xfce_desktop.img.xz", the result there is much better, 49 MB/sec. But the WiFi onboard of LicheeRV Dock is not detected.

balbes150, There is something wrong with performance. I am trying "Armbian_23.09_Nezha_sid_current_6.1.0_xfce_desktop.img.xz" Doing my simplest performance test: dd if=/dev/zero bs=1M count=256 | md5sum The result is 21 MB/sec. Moving windows in Xfce is really sluggish, even after disabling compositor, leaves trail on screen and lags behind mouse movement. Compared to "licheerv-debian-clean-hdmi.zst" from https://linux-sunxi.org/Sipeed_Lichee_RV#Pre-made_images (last in the list). Using kernel 5.18. The same benchmark returns 51 MB/sec. Moving windows is very responsive.

Tested with a vanilla Debian image by johang using kernel 6.1.38, and the problem is not present there.

Sorry, somehow I didn't get a reply notification of your post. On A64 (Orange Pi Win) I do not have this issue. I did not try the patch, but got the 6.4.1 development image a few days ago, and tried that just now, and can confirm the temperature monitoring is working again in that kernel. Now the same image is no longer offered on the download page for some reason though.

Tried a development image with kernel 6.4.1, the problem is still present. Also, Orange Pi Prime is affected in the same way.

Basically, just did 3 consecutive runs of iperf3, and they look like this. And it is not cpufreq, since setting it to performance on all CPU cores does not affect things. Using the current stable Debian image with kernel 6.1.30. Any ideas? $ iperf3 -c 192.168.103.156 Connecting to host 192.168.103.156, port 5201 [ 4] local 192.168.0.101 port 58758 connected to 192.168.103.156 port 5201 [ ID] Interval Transfer Bandwidth Retr Cwnd [ 4] 0.00-1.00 sec 27.3 MBytes 229 Mbits/sec 0 201 KBytes [ 4] 1.00-2.00 sec 26.4 MBytes 222 Mbits/sec 0 195 KBytes [ 4] 2.00-3.00 sec 26.3 MBytes 221 Mbits/sec 0 195 KBytes [ 4] 3.00-4.00 sec 26.3 MBytes 220 Mbits/sec 0 204 KBytes [ 4] 4.00-5.00 sec 26.3 MBytes 220 Mbits/sec 0 206 KBytes [ 4] 5.00-6.00 sec 26.0 MBytes 218 Mbits/sec 0 218 KBytes [ 4] 6.00-7.00 sec 26.2 MBytes 220 Mbits/sec 0 198 KBytes [ 4] 7.00-8.00 sec 26.3 MBytes 221 Mbits/sec 0 204 KBytes [ 4] 8.00-9.00 sec 26.3 MBytes 220 Mbits/sec 0 181 KBytes [ 4] 9.00-10.00 sec 25.7 MBytes 216 Mbits/sec 0 5.66 KBytes - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bandwidth Retr [ 4] 0.00-10.00 sec 263 MBytes 221 Mbits/sec 0 sender [ 4] 0.00-10.00 sec 261 MBytes 219 Mbits/sec receiver iperf Done. $ iperf3 -c 192.168.103.156 Connecting to host 192.168.103.156, port 5201 [ 4] local 192.168.0.101 port 49032 connected to 192.168.103.156 port 5201 [ ID] Interval Transfer Bandwidth Retr Cwnd [ 4] 0.00-1.00 sec 27.8 MBytes 233 Mbits/sec 0 232 KBytes [ 4] 1.00-2.00 sec 26.1 MBytes 219 Mbits/sec 0 204 KBytes [ 4] 2.00-3.00 sec 26.3 MBytes 221 Mbits/sec 0 235 KBytes [ 4] 3.00-4.00 sec 26.6 MBytes 223 Mbits/sec 0 204 KBytes [ 4] 4.00-5.00 sec 25.9 MBytes 217 Mbits/sec 0 198 KBytes [ 4] 5.00-6.00 sec 26.2 MBytes 219 Mbits/sec 0 209 KBytes [ 4] 6.00-7.00 sec 26.3 MBytes 221 Mbits/sec 0 232 KBytes [ 4] 7.00-8.00 sec 27.0 MBytes 227 Mbits/sec 0 368 KBytes [ 4] 8.00-9.00 sec 59.2 MBytes 497 Mbits/sec 0 260 KBytes [ 4] 9.00-10.00 sec 112 MBytes 938 Mbits/sec 0 255 KBytes - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bandwidth Retr [ 4] 0.00-10.00 sec 383 MBytes 322 Mbits/sec 0 sender [ 4] 0.00-10.00 sec 379 MBytes 318 Mbits/sec receiver iperf Done. $ iperf3 -c 192.168.103.156 Connecting to host 192.168.103.156, port 5201 [ 4] local 192.168.0.101 port 44610 connected to 192.168.103.156 port 5201 [ ID] Interval Transfer Bandwidth Retr Cwnd [ 4] 0.00-1.00 sec 116 MBytes 974 Mbits/sec 0 286 KBytes [ 4] 1.00-2.00 sec 112 MBytes 939 Mbits/sec 0 280 KBytes [ 4] 2.00-3.00 sec 112 MBytes 937 Mbits/sec 0 280 KBytes [ 4] 3.00-4.00 sec 112 MBytes 938 Mbits/sec 0 283 KBytes [ 4] 4.00-5.00 sec 112 MBytes 938 Mbits/sec 0 277 KBytes [ 4] 5.00-6.00 sec 112 MBytes 938 Mbits/sec 0 283 KBytes [ 4] 6.00-7.00 sec 112 MBytes 938 Mbits/sec 0 283 KBytes [ 4] 7.00-8.00 sec 112 MBytes 938 Mbits/sec 0 277 KBytes [ 4] 8.00-9.00 sec 112 MBytes 938 Mbits/sec 0 277 KBytes [ 4] 9.00-10.00 sec 112 MBytes 938 Mbits/sec 0 288 KBytes - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bandwidth Retr [ 4] 0.00-10.00 sec 1.10 GBytes 942 Mbits/sec 0 sender [ 4] 0.00-10.00 sec 1.09 GBytes 938 Mbits/sec receiver iperf Done.

Copying DTBs over from the older image into the new one (6.1) does not solve it.

Hello, I'm trying the currently offered Armbian Bookworm images for the Orange Pi Prime, using kernels 6.1.30 and 6.2.16, and notice that there is no support for SoC temperature monitoring, neither in armbianmonitor, nor in /sys/devices/virtual/thermal/. Here is the debug info from 6.2.16: https://paste.armbian.com/cetovulubu Is that a known issue? An older Armbian image that I have downloaded previously, using the kernel 5.15.93, shows the temperature just fine.
