FreeBSD Best Practice
Hello I'm a SysAdmin, I'm wondering whether this is the correct list to ask? I'm looking for FreeBSD Best Practice information, (or a FreeBSD Mailing List, I can join) I want to make sure that all my servers comply to at least some widely accepted standards, so in the event of me getting hit by a bus or being abducted by aliens, another person can take over from me. I have done a search through the mailing lists and this seems like the list to ask.

Re: Announcement: PmcTools callchain capture for RELENG_7
Hi, Does it mean that hwpmc from now will work "out of the box" with new Intel core2 duo/quad processors (like T7500) ? Joseph Koshy wrote: Hello List(s), I am very pleased to announce a patch, by Fabien Thomas, that brings PmcTools' callchain capture features to 7-STABLE. Thank you, Fabien!

Re: Kernel API docs ('make doxygen')
Quoting Mel <[EMAIL PROTECTED]> (from Fri, 11 Jul 2008 15:17:54 +0200): I was wondering if this project is considered obsolete, finished or work in progress. I would say it's in the "it has to prove it's usefulness"-stage. This means not all people are convinced it is useful to have such stuff in our source and someone needs to sit down and do something good to a subsystem to show that it is useful to those people. If it's the latter, I'm happy to do the legwork, like set up proper stubs for each function and structure that people who really know how they work can I think some people would complain if this would be committed to our version control system without consent, and without those stubs being there I don't expect that the stubs get converted to proper docs. So giving advice to just go ahead may be a waste. adjust. There's a lot already in there with normal comments, that can become documentation by simply adding an extra asterisk. Decide for yourself if you are willing to invest your time to convert the existing docs in the source into doxygen docs. In src/tools/kerneldoc/subsys/ is already a framework to handle the doxygen stuff per subsystem (not all subsystems are done there). It would be most beneficial to start with one of the subsystems which are already available there. In case you want to play around there, send me a mail and I try to get some time to commit some fixes. In case you are interested to work on a subsystem which is not represented there, you can email me too (but it should be easy to copy&modify an existing file). But again, no guarantees that any changes to the source get's committed.

I have some knowledge about initrd in Linux in which I can change the device for '/' and than reboot the machine so that it takes a new device for '/'. How can I achieve this in FreeBSD?

Re: Can I change the device of the "/" mount point at boot time.
This is not exactly what I wanted. I will try to elaborate myself. I am creating my own device which will act as a new boot slice which must be mounted as '/'. New device will process i/o calls and then redirect the i/o calls to original device of '/'. Now since I cannot unmount '/' and mount it again with my new device while system is running, I will have to find a way to tell kernel to mount my new device as '/' from next time onwards it boots. does anyone have suggestions on this?

That's pretty much exactly what vfs.root.mountfrom does. Edit /boot/loader.conf to add a line: vfs.root_mountfrom="fstype:devicespec" and you're good to go. The kernel will boot from your default root partition, then remount root using the value of that variable.

Re: Can I change the device of the "/" mount point at boot time.
Hi, Thanks a lot Mike. But the problem is the device I am talking about is not the physical device. I am writing a driver which will create a virtual device and all the i/os done on this virtual device will be ultimately redirected to the original device. Correct me if I am wrong, but I guess the loader will try to mount my new device on '/' and then load the modules into the kernel. Since my driver would not be loaded at that point in time, it will fail to even mount '/'. Am I right? Or can our drivers get loaded before loader mounts '/' ? Thanks, --Tapan.

The kernel will boot of off a physical devices - pretty much required. At that point, you can use boot.config to load modules from that device, including any needed to keep your driver happy. Set the vsf.root.mountfrom to tell the kernel what where to find what's going to become the root file system when it gets to that point. The process is documented in the man pages, starting with say boot(8).

Re: Can I change the device of the "/" mount point at boot time.
Thank You Mateusz and Mike. I guess I am clear with my doubt now. I will also go through the man pages to go into depth of it. Thanks, --Tapan.

Re: SCHED_4BSD bad interactivity on 7.0 vs 6.3

It seems like there has been a regression in interactivity from 6.3-RELEASE to 7.0-RELEASE when using the SCHED_4BSD scheduler. After upgrading my single-cpu amd64 box, 7.0 has much worse latency. When running a kernel compile, there is a noticeable lag to echo my typing or scroll my browser windows, and playing an mp3 frequently cuts out for a second or two. This did not happen on 6.3-RELEASE. Are you sure it's not the x.org server bug that was present in the version shipped with 7.0? Update to the latest version and see if your X interactivity improves. Yes, I had not yet upgraded my x.org port when testing this, so it was the same x.org that was fine under 6.3. Also: I wrote a small program which forks two processes that run gettimeofday() in a tight loop to see how long they get scheduled out. On 6.3 the maximum latency is usually under 100 ms. On 7.0 it is 500 ms or more even when nothing else is running on the system. When a compile is also running it is sometimes 1400 ms or more. This test shows a difference even in single user mode, when X is not running at all. It shows *a* difference, but perhaps not the *same* difference. Please humour me and rule it out. Okay. I am in the process of recompiling all my ports, so after that is done I will boot with a GENERIC kernel and see what happens. After trying this, I can't seem to reproduce the sound skipping behavior, unless I do something fairly extreme like "make -j 6". But the mouse does seem to skip when a compile is running, so I do believe there is a regression. -- Nate Eldredge [EMAIL PROTECTED] ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"

The critical thing is that the loader must read the kernel (and modules, config etc..) from a disk the BIOS knows about. After that you can use any device the kernel knows about. As for the virtual device aspect - could you use a geom class to do you want?

Re: Can I change the device of the "/" mount point at boot time.
Hey, Thanks Deniel for the reply. I am aware of the fact you mentioned and will keep in mind. Well what i am trying to achieve is a simple thing to write an interception driver to catch all the i/os going to a particular device, do some manipulations on it and than let it through to the original device. Well as you mentioned about geom, I have recently posted a mail on GEOM mailing list as I could not find geom doing interception, the discussion is still on (You can see the mails with subject line "Can GEOM be used to intercept the I/o calls to an existing mounted device?"). Any sugessuions on interception driver will be helpful? As an interception driver is not possible, for time being I am going towards the redirection concept which will require a reboot and changing the devices on the mount points. For redirection driver, I dont think I will need geom. I can directly create a new device. Rather I think it would be an overhead using geom for a virtual device. Any thoughts on both the issues?
