[solved] Re: Linking libraries for compat_linux
On Dec 19, 2008, at 9:46 AM, Chris wrote: I've bumped into a library I can't resolve and I must have a disconnect in how the linux_compat works because I can't see how it could be solved. I found that using FreeBSD Port fam for the daemon with openSUSE 10 fam 2.7.0 for my /compat/linux/lib/libfam.so* worked. Other fam versions from other linux distributions failed. I'm able to detect file changes with a linux binary that employs libfam.so. I tested it using the fileschanged application provided with the linux fam version. qbmonitord also works with this configuration. I have the following: * compat_linux enabled in the kernel, * /usr/ports/emulators/linux_base_fc7 * sysctl kern.fallback_elf_brand=3 * rpm2cpio to alter rpms * cpio to create the directories and place the files where they belong in /compat/linux. I have a program that now has all it's libraries resolved but one in preparation to attempt to run the Linux Quickbooks install on FreeBSD. The ldd output, prior to installing /usr/ports/devel/fam (a required shared library) looks like this. ldd ./opt/qbes7/util/qbmonitord ./opt/qbes7/util/qbmonitord: libfam.so.0 = not found libpthread.so.0 = /lib/libpthread.so.0 (0x28072000) libstdc++.so.6 = /usr/lib/libstdc++.so.6 (0x28088000) libm.so.6 = /lib/libm.so.6 (0x28171000) libgcc_s.so.1 = /lib/libgcc_s.so.1 (0x28198000) libc.so.6 = /lib/libc.so.6 (0x281a4000) /lib/ld-linux.so.2 (0x28054000) I install fam to get rid of the not found, perform the following link: ln /usr/local/lib/libfam.so.0 /compat/linux/lib/libfam.so.0 and then I get this: ldd ./opt/qbes7/util/qbmonitord ./opt/qbes7/util/qbmonitord: ./opt/qbes7/util/qbmonitord: error while loading shared libraries: / lib/libfam.so.0: ELF file OS ABI invalid ./opt/qbes7/util/qbmonitord: exit status 127 which kind of makes sense since this library is not a linux library. I'd read that I don't need to brandelf -t linux a library but I tried that anyway, realizing it was likely meaningless (or harmful). It didn't help of course. My next thought was to try and get a libfam.so.0 binary from a linux distro but stopped when it occurred to me that it would be illogical since fam uses kqueue on FreeBSD rather than something called imon. imon is not available for FreeBSD so a linux version shouldn't be able to function if it expects that. On FreeBSD, fam configures itself to not use imon. What is the appropriate course of action to get a linux flavor shared library for fam (or anything which runs into such conflicts) that will work on FreeBSD yet be recognized as suitable for linux under the compat mode? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions- unsubscr...@freebsd.org ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Re: Status of hyperthreading in FreeBSD
Brett Glass wrote: Which raises a question: What's the status of FreeBSD's support for hyperthreading? As far as I know, after it was revealed that some processes on a machine with hyperthreading could spy on others, and Yes, but that is a hardware problem which is independent of the operating system (it's present in all of them). also that hyperthreading didn't always improve performance on high end processors, the feature was turned off by default. But on single-user Yes, especially on the early Pentium 4 CPUs. This is also OS-independent. machines, or on servers where the CPU was likely to be shared by two processes that were both privileged anyway, it might make sense to re-enable it. But has this feature of the scheduler been maintained well enough for this to be a good idea? If not, would it worth looking into updating it so that FreeBSD runs well on the Atom? It's as good as it can be on recent ULE2 scheduler. ULE2 has support for HTT but there's not much that can be done at the scheduler level as the Atom is single-socket, single-core CPU. Atom's HTT is actually pretty good - I saw up to 25% more performance simply by using multithreading in 7zip's compression benchmark (on WinXP, though). Of course, OTOH it uses about that much more transistors on the CPU die so it's not exactly free performance. signature.asc Description: OpenPGP digital signature
disk error / reboot / 6.3
Hi, We are running 6.3 on a fileserver with a couple of data disks. Once the server encounters an error on a data disk (os disk is separate) the server will reset itself without warning. We can usually identify the problem disk with a smartctl, the disk will show 'Offline uncorrectable errors'. The fact that the server reboots itself, is this normal? Can we prevent this from happening? The disks are attached to the on-board sata ports of the mainboard itself, so no (raid)controllers whatsoever. We also do not use software raid.

Re: Status of hyperthreading in FreeBSD
as far as i know, just enabling smp will allow ht to function. also, i don't know if intel changed ht in the new atom processor, they could have. is FreeBSD's smp special in some way that it would be the exception to the following statement. I know there was a lot of changes made in the new ULE2 scheduler maybe that is why? /* Hyper-threading relies on support in the operating system as well as the CPU. Conventional multiprocessor support is not enough to take advantage of hyper-threading.[1] For example, even though Windows 2000 supports multiple CPUs, Intel does not recommend that hyper-threading be enabled under that operating system. */ I found this in wikipedia at the following link http://en.wikipedia.org/wiki/Hyper-threading Sam Fourman Jr. Fourman Networks ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
