anything like top but for USB?
Hi, Is there a tool to show statististics of USB devices? Like how much there is free bandwidth, which endpoints are hogging bandwidth and so on? Ideally it could be like top but for USB or a page on systat or something like that. Are there technical reasons or am I just bad at searching? Best regards, Hannu Vuolasaho
Re: What is the best way to move a VM to a bigger image?
Hello everyone, And now the conclusion. I indeed ran the installer to get partitioned disk easily and the result was just the bsd and base file set installed system. That system worked fine. Then I dumped and restored the partitions or filesystem as FAQ instructs. Anyway I got sha256 identical systems except /dev, /tmp and /etc/fstab The comparison was interesting. $ find / -type f >/tmp/files.txt $ wc /tmp/files.txt 10 100572 5291532 /tmp/files.txt That was weird. No-one should have exactly 100k files in their system. I don't understand why during startup all programs just dumped core. I would suspect some library randomization. After re-installing bsd and base fileset again the new disk booted nicely. I believe relinking the kernel and other end of installation steps would probably be enough to fix that kind of problem. So that was my way of doing this operation. Best regards, Hannu Vuolasaho
What is the best way to move a VM to a bigger image?
Hello, I made a silly mistake when I set up my VM and my disk image is too small for my next operation. My plan is to give the new image to the VM, run a minimal install on it so I get the boot loader installed. Also disklabel will be good. After that I remove all the files and mount the old VM image to another part of the tree. Rest is just a dump and restore operation. And checking the /etc/fstab Is this a good way to skin this cat? Or is there a better way to do it? Best regards, Hannu Vuolasaho

Can I use OpenBSD services AND have > it act as a desktop workstation on the same machine? > Hi, My answer is no and yes. This is based on the laziness factor. No part is that sometimes the services may work locally OK but not work from the network. Also it is much nicer to work from the sofa with a laptop and not listen to the server making its noise. The yes part is that it is so nice to have even some real computer to surf when everything seems to be broken and the next step would be to start all over again. It is so nice to start xenodm, login and surf to find the solution to the problem and fix it. if some part of the network configuration is still working. Best regards, Hannu Vuolasaho
Re: Question to usbdevs and dmesg
Hi! There is also sysutils/usbutil which provides usbgen package With that you could get the USB descriptors with something like: doas usbgen -D -v -f /dev/ugen1 on OpenBSD. However AFAICT it works with generic ugen devices. I don't know how to debug for example a USB mass media device. That being said, I have missed many times non-existing verbosity level for usbdevs which would dump at least device descriptor. Would this be desirable enhancement?

Re: development best practices

The scenario is that I write some patch which fixes something and then gets to the project tree. Then the testing and fixing cycle starts again. I know a few programs which are easy to compile in ~/src but writing a port is PITA. Naturally that kind of port won't ever get to CVS but for testing and development. Best regards, Hannu Vuolasaho
Extending rtwn(4) to RTL8723BE
Hi! I am in the begin of extending rtwn(4) to RTL8723BE. How hard it would be if there is only one letter changed in chip name if AE is already supported. :) My progress so far has been detecting the chip, reading the rom table and loading the firmware. Any use of the interface causes log message of RF not powered, which is understandable and I will dig into it after the rom part works. I have few questions Does the rtwn firmware package ship already RTL8723BE firmware? I have rtwn-rtl8723befw_36 directory in /etc/firmware. Just asking to make sure I load right firmware as there are no easily findable changelogs for firmware packages. As there was some preliminary work done to RTL8723BE, has someone gathered info already? Or is the boot linux compile more debugging to driver and figure out what is happening the only slow way? Best regards, Hannu Vuolasaho
Old Sony Vaio and ACPI problem
Hello everyone! I'm trying to run rather old 32-bit Sony Vaio with 5.4 fresh install. Its chassis says Sony-Vaio-PCG-7M1M and dmesg bios0: Sony Corporation VGN-FS515B Anyway. If I have APM enabled iwi0 doesn't work. On the other hand if I disable apm from UKC I get thermal shutdown but iwi works. And that machine isn't hot. It's on my lap. Is it possible to configure thermal shutdown off without recompiling kernel or will this information help to add more apm tricks to next release? This data is collected with SYS=Sony-Vaio-PCG-7M1M-disable-apm mkdir $SYS; cd $SYS acpidump -o $SYS $SYS.aml dmesg $SYS.dmesg cd ..;tar czf $SYS.tgz $SYS http://www.cs.tut.fi/~vuolasah/openbsd_vaio/Sony-Vaio-PCG-7M1M-default-boot.tgz http://www.cs.tut.fi/~vuolasah/openbsd_vaio/Sony-Vaio-PCG-7M1M-disable-apm.tgz Best regards, Hannu Vuolasaho
