sysctl machdep.hlt_logical_cpus affects kernel HZ?
One of my colleagues has just noticed that setting: sysctl machdep.hlt_logical_cpus=1 appears to double the kernel frequency as reported by systat on 5.2.1-RELEASE-p11. Is this correct? What are the implications? How can this be corrected? Steve This e.mail is private and confidential between Multiplay (UK) Ltd. and the person or entity to whom it is addressed.

Soundcard tweaking: `mixer' v. `sysctl' ?
[drop me from replies and I'll catch up from the archives RSN] I seek guidance in my hideous hacking. I have multiple sound cards based on the CMI8738 chip with spdif input in one machine, for which I was using hacked kernel modules to select either optical or coaxial spdif input from both cards. The cmpci driver under NetBSD has far more functionality, allowing one to use mixerctl/audioctl to access much more than FreeBSD's mixer or sysctl can give me. Now that I'm wanting to record from different sources on the two cards, as well as having been spoilt by what NetBSD is able to offer in monitoring and whatnot, I'm wanting to hack comparable functionality into my FreeBSD kernel modules. My first ugly hack makes use of two added mixer inputs to allow me to select one of the two spdif inputs independently of the other card, with `mixer', whee. After I had had no luck with my wish to use a sysctl to select recording source like the NetBSD mixerctl program. First question, am I missing anything that gives sysctl-like control over sound devices, under my FreeBSD4? Secondly, after another attempt to whup the sysctl into submission, I had success. Yow. So I was able to duplicate my `mixer' input source selection hack as a `sysctl' input source selection hack, as well as introduce a handful of other sysctl knobs to be used to tweak things important to me, leaving the door open for others. So, should I give up on `mixer' in favour of `sysctl' to select recording source (the spdif inputs are exclusive), or is it still reasonable/preferable to use `mixer =rec dig1' as my earlier hacks allow (haven't tried to make those disappear from the mixer itself, as the level cannot be adjusted) ? In addition, for something like enabling spdif monitor to the analog outputs (which NetBSD's mixerctl spdif.monitor allows me to do), should this be done with a sysctl, as my later hack does, or by something else? There's already one sysctl for this sound driver to enable spdif playback output, so I would imagine this is the way to go. Apologies for my stupidity. And I'll submit (ugly) patches, when I'm happy with my hacks. If desired. thanks barry bouwsma ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]

5.3 release snd_ich strange behaviour
I've installed 5.3-RELEASE recently and pretty happy with it. But i've noticed some strange behaviour. I've added snd_ich_load=YES to my /boot/loader.conf to enable sound in boot time. Reboot machine and everything was working ok. But then i noticed that cooler on my notebook starts more often then without snd_ich. Running top shows that machine is about 15-20% in interrupts. Unloading snd_ich makes top showing interrups about 0-1%. Then i loaded snd_ich by hand (kldload snd_ich) and the problem dissapeared, top shows 0-1% and cooler starts as without snd_ich. I commented this string in /boot/loader.conf and rebooted the machine. Then load snd_ich by hand. Everything is ok! I assumed that it was some strange thing and uncommented string in loader.conf and rebooted. The situation with 15-20% inturrupts repeeted! However kldunload kldload resolves it. So the only suitable solution for me was to load snd_ich using rc.d Thanks!

True SAN clustering means that you have a web of disks directly connected to the SAN (iSCSI, FibreChannel, etc), and two or more servers on the SAN that see those disks as a single filesystem (actually a bit more complicated than this, but you get the point). If one server goes down, no access to data is lost since the disks can be reached from any other server on the SAN that is participating in the clustered FS.

OpenAFS is a network-centric system that replicates data across its nodes, I think, and each node has a cache. A clustered filesystem uses a single block of shared storage (usually on a fibre-channel SAN, but you can also use shared scsi on a 2-machine cluster) that all servers access directly. The magic is getting the locking right to make sure the servers don't stomp on each other's data.

The hard part of a new installer, or any complex UI application, is the framework that ties events and actions together. The easy part is writing the modules on top of that that do the discrete actions. While I see quite a few rough edges in the upper layers of the DF installer, it seems like quite a bit of work is going into the framework, and that's why I'm actually so interested in it.

It's fairly good at the simple task that it does, but it's becoming harder and harder to fix bugs and extend functionality in it. It's also fairly unfriendly to those of us who haven't been using it since 1995. The DFly folks have some very interesting work in this area (www.bsdinstaller.com) and it would be very good to see if we can collaborate with them on it. Please, don't change /stand/sysinstall *too* much, there is really nothing wrong with the interface of it, and it's what makes FreeBSD so quick to install. At the very least, make sure you do NOT go for an XFree86 installation, and keep to the KISS approach. Visually wise, theres nothing wrong with the current installer.. and its one of the things I promote about FreeBSD -- the ease to install. It's small, its fast.. and it works, however in error situations it does mess up badly. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]

I find X windows to be a bit too compute intensive.

SANs are all the rage these days, and clustered filesystems that allow data to be distributed across many storage enpoints and accessed concurrently through the SAN are very powerful. RedHat recently bought Sistina and re-opened the GFS source code, so exploring this would be very interesting. This sounds very close to OpenAFS. I don't know what distinguishes a SAN from other types of NAS. OpenAFS does everything you mentioned in the above paragraph. OpenAFS _almost_ works on FreeBSD right now. Later, Jason C. Wells Well, AFS requires an intelligent node in front of each disk. True SAN clustering means that you have a web of disks directly connected to the SAN (iSCSI, FibreChannel, etc), and two or more servers on the SAN that see those disks as a single filesystem (actually a bit more complicated than this, but you get the point). If one server goes down, no access to data is lost since the disks can be reached from any other server on the SAN that is participating in the clustered FS.

1. Keyboard multiplexer. I actually fail to stop thinking about a complete syscons and pcvt replacement. You know, the one and only console implementation that makes all others obsolete. Big plans, little time, yada yada yada... It would be nice if one would still be able to use the keyboards separately too, even if you have to recompile the kernel for that. One nice usage would be on HP's quad kiosk machine. It is a single processor box with 4 x screen, keyboard and mouse, and then 4 people can use it.

Maybe something like apple's interface would be a good alternative [for those who don't need X-windows' powerful graphic features]. What makes you think so? X was originally desgined for systems with little memory and processing power, certainly a lot less than today's AMD and Intel space heaters. There are some features that do indeed require more CPU, like antialiasing. That's the price to pay for eye candy. Things like the composite and damage extensions do wonders to help in those areas and make things like true transparency and alpha blending possible. So, in time, X won't be that different from Aqua in its use of hardware. The lack of speed in some apps can be blamed mostly on the toolkits. GTK+ 1.2 was a speed demon, GTK+ 2.x is a lot slower. There are some people working on a fast Pango code path that could make english text rendering fast again. X gives you network transparency out of the box. I used an old SGI Indy as an X term to connect to my FreeBSD box for years, and it worked like a charm over a 10Mbit connection. Replacing X means writing something that's API compatible, or writing an X server on top of your new display system, so that you don't have to throw the thousands of X apps into the trashcan. About some of the other comments in the thread. IMHO using bsdinstaller as a base could be beneficial for both groups and save duplicated work. I'm sure they'll be glad to get internacionalization patches. I agree that a journaled filesystem is really needed if you want to manage multi TiB partitions. As rock solid and tested softupdates is, fsck is not an acceptable solution in this case. Some people were working on a port of XFS, has any progress been made? I tried contacting them some time ago, but never got an answer. Sounds like a very interesting, though.
