I am trying to enable AF_XDP zero copy mode and i see the error in Cent OS 8(kernel 4.18), but SKB mode and DRV mode with copy works fine. The driver is ixgbe 5.6.5 which supports AF_XDP zero copy as per the documentation. strace shows the failure is during bind
./af_xdp_user -d eth2 -z -q 1
bind(3, {sa_family=0x2c /* AF_??? */, sa_data="\4\0006\1\0\0\0\0\0\0\0\0\0\0"}, 16) = -1 EOPNOTSUPP (Operation not supported)
The ethtool shows i have combined queues and not separate rx/tx queues. Is that a problem?
[root#localhost ~]# ethtool -l eth2
Channel parameters for eth2:
Pre-set maximums:
RX: 0
TX: 0
Other: 1
Combined: 63
Current hardware settings:
RX: 0
TX: 0
Other: 1
Combined: 9
[root#localhost ~]# ethtool -i eth2
driver:
ixgbe

Any ideas what is missing?

1) I've been using Ubuntu 18.04 with Windows 10 dual boot for some months now. Today suddenly my sound stopped working on Ubunutu. Activities -> Sound menu shows only "Dummy Output". All fine on Windows though.
2) Output of lsmod is:

Please help - how do I proceed?
Similar issue with "Dummy Sound" on Ubuntu 18.04 also with a NVIDIA card. This solved it for me:
Edit /etc/modprobe.d/alsa-base.conf as root and add options snd-hda-intel dmic_detect=0
Edit /etc/modprobe.d/blacklist.conf as root and add blacklist snd_soc_skl at the end of the file.
After making these changes, reboot your system.
More details (and credits): https://www.linuxuprising.com/2018/06/fix-no-sound-dummy-output-issue-in.html
I had the same problem, and tried the solution given by #maartenor without success.
Eventually I got the sound back by upgrading linux kernel to the last HWE stack, for me it was 4.15.0-106-generic to 5.3.0-59-generic.
The command to do this :
$ sudo apt install linux-generic-hwe-18.04
Edit the file /etc/modprobe.d/alsa-base.conf and add the following lines:
options snd-hda-intel dmic_detect=0
options snd-hda-intel model=laptop-amic enable=yes
The first line is to enable the speaker, the second for the internal microphone.
Good luck!
Got this answer from Reddit. Worked like a charm for me!
Link : https://www.reddit.com/r/linuxmint/comments/fltlrl/no_sound_on_acer_swift_3_with_kernel_53/
Try this..
Open your terminal
sudo apt update && sudo apt install alsamixer
run alsamixer in your terminal.
press arrow right til you go to sound option (if headphone go to HEADPHONES bar).
press M to unmute.
press up/down to adjust the volume.
press Esc to exit alsamixer.
Following steps worked very reliably. It does not fix the audio-losing-after-suspend issue permanently, but instantly as a command to run after back from suspend.
Use lspci to get the audio card location (0000:00:1f.3). On my machine,
$ lspci
00:1f.0 ISA bridge: Intel Corporation H110 ...
00:1f.2 Memory controller: Intel ...
00:1f.3 Audio device: Intel Corporation 100 Series/C230 Series Chipset ...
00:1f.4 SMBus: Intel Corporation 100 Series/C230 Series Chipset ...
Then, (make sure the directories below exist)
$ echo 1 | sudo tee /sys/bus/pci/devices/0000:00:1f.3/remove
$ echo 1 | sudo tee /sys/bus/pci/rescan
I believe the audio driver/hardware is stuck. So we remove the device driver, and rescan the PCI bus to get audio back.
i found answer above not work on my computer, and i solve this problem by accidient , this is script i use , most same as answer above, but at last, u need mute then unmute auidio. sleep a short moment after command is necessary here if you put script in sh file then excute it , use sh -c is for file redirection for root
REST=0.5
#make sure Audio always actived
sudo sh -c 'echo 1 >/sys/bus/pci/rescan'
sleep $REST
DEVICE_ID=$(lspci -D | grep Audio | awk '{print $1}')
sleep $REST
sudo sh -c 'echo 1 >/sys/bus/pci/devices/0000:00:1f.3/remove'
sleep $REST
sudo sh -c 'echo 1 >/sys/bus/pci/rescan'
sleep $REST
#mute then unmute to restart audio
amixer -D pulse sset Master mute
sleep $REST
amixer -D pulse sset Master unmute
I am using a tinkerboard with an android + chroot linux. When I try to read temperature by the following command:
cat /sys/class/thermal/thermal_zone1/temp
I get the following error :
cat: /sys/class/thermal/thermal_zone1/temp: No such file or directory
If I run the tinkerboard directly with a linux distribution rather than android I am able to read the temperature by the above command.
The tinkerboard uses the RK3288 cpu which has a TS-ADC temperature sensor.
Any suggestions?

After some research by my colleague:
The kernel was missing the required drivers. Fortunately the newest updates to the kernel included the thermal sensor. It now works.
We have expend existing LUN size on EMC Storage and now i want to re-scan on Host side but i don't know how to figure out SCSI ID of that specific LUN. I am new to storage.. This is what i am doing but don't know whether it is a right way or not

Here i am running find command on sdX device to find out SCSI ID to i can do echo 1 > /sys/bus/scsi/drivers/X:X:X:X/rescan to do re-scan LUN
$ find /sys/devices -name "*block*" | grep -e "sdaj" -e "sdaw" -e "sdj" -e "sdw"

or there is a alternative or other way to scan LUN?
I like to use the "lsscsi" program, which is probably available for your distribution.
% lsscsi

As for rescanning the bus, that's pretty much it.
So, I have had this working on Ubuntu before. But then I upgraded to 11.10. Now, no such luck.
Note: if you are still messing with getting this to work on eclipse, you might want to try this command line stuff... if it doesnt work here, its not going to work in eclipse.
I have this error:
avrdude: stk500v2_command(): command failed
avrdude: stk500v2_command(): unknown status 0xc9
avrdude: stk500v2_program_enable(): cannot get connection status
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.
I have tried with all different configurations.
ie: -B 1 ,10, 1000,
-F doesn't help becuase then you just get back 000000 or whatever as your serial.
Also, I should mention, clearly from the output below, you can see that it gets to the programmer and even to the target board and reads its voltage out.
You can also see the target chip reset. (ie: i have tested on a number of devices includeing a DB101 and you can see when it resets)

The board AND the programmer work with AVR studio on another machine.
Apparently a lot of people have this issue on Linux. :(
Dont really want to have to dig up a winblows box.
I had a really hard time getting mine to work as well. In the end, I tripped over http://wiki.dataflow.ws/Electronix/AvrIsp2OnOSX and found that I had actually missed a package. After installing uisp
sudo apt-get install uisp
I ran
sudo avrdude -c avrispmkII -p m168 -P usb: -B 8 -v -U lock:w:0x3f:m -U lfuse:w:0xff:m -U hfuse:w:0xdf:m -U efuse:w:0x0:m
And got a nice pretty green LED.
Just for the record (same error message) and because I also spent some time fiddling with my AVR ISP MKII:
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.
It did work OK for me only after adjusting the timing using the -B parameter! Looks like even a current mini PC is just too fast.
Avrdude now works for me reliably under straight Debian 7. Also, it works under Windows 8 with WinAVR driver installed, then VirtualBox VM running a Debian 7 non-UI installation, after passing through the AVRISP to the VM in VirtualBox.
avrdude -c avrispmkII -P usb -p t13 -B 10 -v
