[RFC] prototype of top(1)'s CPU current frequency display
I want to see CPU current frequency on top(1), because I want
to see relation of process status (CPU usage) and cpu current
frequency using powerd(8) on the fly. In recently, many CPUs
for servers like Xeon support frequency changing like Speed
Step Technology. I run powerd(8) on these servers. So I
should know performance issue, whichever program performance
or server performance. I wrote a little usability patch.
But I don't think that my code is not good:-(. So please
improve my code.
Wellknown problem.
1. assume only 1 CPU.
2. assume dev.cpu.0.freq is always exists.
3. display position is good?

global date via module howto
Hi, I have the following problem: module A int x; module B extern int x; Module A is loaded, module B can't be loaded cause of unknow 'x'. What should I do to make x global? PS. I am working on porting irda support for USB devices from NetBSD. The current model consists of two layers hw and sw. hw is the usb device driver. sw is some software layer the same for all device and it is a child on top of hw 'bus'. To make this working I need to add DRIVER_MODULE for each 'bus'. To make sw independent from the bus I need to export _driver and _class structures and put DRIVER_MODULE in 'bus' code instead of 'child'. rik ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]
About loader(8) forth
Hi folks, I'm trying to understand how the loader forth works to see if it's possible to develop something similar to knoppix boot menu and use it for FreeSBIE. Just to have a try, I replaced /boot/beastie.4th with file a containing only: . Welcome to FreeSBIE exit then I deleted the line mentioning beastie-start from /boot/loader.rc and rebooted my machine. I wanted the machine to print Welcome to FreeSBIE and then escape to loader prompt. Saying it didn't work is probably not enough. I got an error message saying Compile failed followed by some codes I didn't had the time to copy because my machine auto-rebooted. I must admit I'm a forth newbie. What so important id I miss? Any hint that will make me proceed in the correct direction will be much appreciated. Thanks in advance Best regards -- Matteo Riondato FreeBSD Committer (http://www.freebsd.org) G.U.F.I.

PCI express support?
I got a PCI express version of the Intel gigabit adaptor to try. Heh. Comes with a big-ass heatsink on the card. I found that a bit amusing. But it doesn't probe up. Is this because PCI Express is not supported (1x in this case --- the little slot), or because I need to put in the constants for this card?

Re: Adding remove file option to BSD tar?
What do people think about adding an equivalent to gtars --remove-files? Shouldn't be too tricky. If you think you know how to implement it, send me the diffs. Doing this safely is nearly impossible, of course. In the compressed case, the compression pipeline buffers a LOT of data ... Actually, this might not be as hard as I first thought. Just keep a FIFO of files added to the archive, and a running count of the total size of those files. When the count exceeds some limit, delete the oldest file in the queue and update the size. If you keep the limit pretty high (2MB? 10MB?), then you can be pretty confident that files will not get deleted before they have been safely added to the archive.

Aqcuiring full path to running process from outside the kernel
I've been playing with Open Watcom for a bit in FreeBSD and for a while there's been one stumblim block for further advancement. Watcom uses a method for storing program messages etc. where these messages are stored as a resource file inside the executable itself. As the commands are usually invoked without the canonical path, the tools cannot find the resource portion stored inside. This far I've been looking for some solutions from which none seem to work too well. vn_fullpath (9) is running only inside kernel I think, and with the approach using kvm_openfiles and kvm_getprocs I can only get the command without the path (there are vnode etc. structures inside the kinfo_proc structure, but those seem to be unavailable from user space). Of course /proc might help in here, but I rather kept the code compilable on very vanilla system. Any pointers on how to proceed would be welcome. -Reko ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]

In general, what you're asking can't be done on Unix. The vn_fullpath man page notes this by pointing out that it makes a best effort, and giving a list of reasons why it isn't reliable. Many of those apply in your case as well. However, you can also make a best effort. Check argv[0] to see if you have an absolute path. If not, do what the shell would do to find the executable - look for it on $PATH. Once you've found it, call realpath(3) to canonicalize the path. mike -- Mike Meyer [EMAIL PROTECTED] http://www.mired.org/consulting.html Independent Network/Unix/Perforce consultant, email for more information. ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: Aqcuiring full path to running process from outside the kernel
Of course I did find about the CTL_KERN.KERN_PROC.KERN_PROC_PATHNAME sysctl method of grabbing the path just about the same time Mike replied to my query... Seems that either of the ways suggested by Mike could be used as fallback.

You might want to try the latest Intel driver from their site, or alternatively I think the latest driver has been merged to 6.1-STABLE. I had a Intel Pro/1000 PT, and it was only recognised in -CURRENT. Using the official Intel driver allowed me to get it running on 6.1. This was prior to the recent MFC of the newer driver. -Antony ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]
