It does compile cleanly against head, though. I don't think it should change any behavior, I tried to keep the essence of the code path the same. It was suggested that I break up my multipass suspend/resume code into incremental parts, so this is part one. It adds a BUS_SUSPEND_CHILD/BUS_RESUME_CHILD, as well as helper functions, bus_generic_suspend_child()/bus_generic_resume_child(), and modifies the PCI driver to use this new facility. I'd like some feedback, and testing of this, to make sure I didn't break anything.

installing packages into a mounted system
Hello, I've compiled ~1300 packages with poudriere 3.1pre on a 'head' system; went fine; mounted below /mnt is a complete new system (an USB key) which boots fine alreaday; the 1300 resulting *.txz file are copied into /mnt/PKGDIR in the past, using the pkg_* tools, I could just install the packages with: # PKG_PATH=/PKGDIR # export PKG_PATH # chroot /mnt pkg_add xorg-7.7 # chroot /mnt pkg_add kde-4.10.5 ...

I thought I will compile a pkg-static and move this to into the /mnt system too with # chroot /mnt mkdir -p /usr/local/sbin # cp -p /usr/local/sbin/pkg-static /mnt/usr/local/sbin pkg-static(8) works there, bringing up the help with: # chroot /mnt /usr/local/sbin/pkg-static help But, how do I specify that it should install for example xorg-7.7 having its file (and all others) in /mnt/PKGDIR/xorg-7.7.txz It seems to look for some files digests.txz or repo.txz which I do not have: # PACKAGESITE=file://PKGDIR export PACKAGESITE # chroot /mnt /usr/local/sbin/pkg-static install xorg-7.7 Updating repository catalogue pkg-static: file://PKGDIR/digests.txz: No such file or directory pkg-static: No digest falling back on legacy catalog format pkg-static: file://PKGDIR/repo.txz: No such file or directory Any hints?

(I have a local hack that adds a new malloc option to explicitly memset() new pages allocated via mmap() that gives the same benefit without the junking overheadon each malloc() / free(), but it does increase physical RAM usage.) John, A couple small steps have been taken toward eliminating the need for this hack: the addition of the page size index field to struct vm_page and the addition of a similarly named parameter to pmap_enter(). However, at the moment, the only tangible effect is in the automatic prefaulting by mmap(2). Instead of establishing 96 4KB page mappings, the automatic prefaulting establishes 96 page mappings whose size is determined by the size of the physical pages that it finds in the vm object. So, the prefaulting overhead remains constant, but the coverage provided by the automatic prefaulting will vary with the underlying page size. Yes, I think what we might actually want is what I mentioned in person at BSDCan: some sort of flag to mmap() that malloc() could use to assume that any reservations are fully used when they are reserved. This would avoid the need to wait for all pages to be dirtied before promotion provides a superpage mapping and would avoid demotions while still allowing the kernel to gracefully fall back to regular pages if a reservation can't be made. -- John Baldwin ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

It does compile cleanly against head, though. I don't think it should change any behavior, I tried to keep the essence of the code path the same. It was suggested that I break up my multipass suspend/resume code into incremental parts, so this is part one. It adds a BUS_SUSPEND_CHILD/BUS_RESUME_CHILD, as well as helper functions, bus_generic_suspend_child()/bus_generic_resume_child(), and modifies the PCI driver to use this new facility. I'd like some feedback, and testing of this, to make sure I didn't break anything.

The uncommitted patches, referenced in the article, are available as https://kib.kiev.ua/kib/pig1.patch.txt https://kib.kiev.ua/kib/patch-2 A followup to the original paper. Most importantly, I identified the cause for the drop on the graph after the 30 clients, which appeared to be the debugging version of malloc(3) in libc. Also there are some updates on the patches. New version of the paper is available at https://www.kib.kiev.ua/kib/pgsql_perf_v2.0.pdf The changes are marked as 'update for version 2.0'. Would you mind trying a default (non-PRODUCTION) build, but with junk filling turned off? adrian@adrian-hackbox:~ % ls -l /etc/malloc.conf lrwxr-xr-x 1 root wheel 10 Jun 24 04:37 /etc/malloc.conf - junk:false That fixes almost all of the malloc debug performance issues that I see without having to recompile. I'd like to know if you see any after that. OTOH, I have actually seen junk profiling _improve_ performance in certain cases as it forces promotion of allocated pages to superpages since all pages are dirtied. (I have a local hack that adds a new malloc option to explicitly memset() new pages allocated via mmap() that gives the same benefit without the junking overheadon each malloc() / free(), but it does increase physical RAM usage.) John, A couple small steps have been taken toward eliminating the need for this hack: the addition of the page size index field to struct vm_page and the addition of a similarly named parameter to pmap_enter(). However, at the moment, the only tangible effect is in the automatic prefaulting by mmap(2). Instead of establishing 96 4KB page mappings, the automatic prefaulting establishes 96 page mappings whose size is determined by the size of the physical pages that it finds in the vm object. So, the prefaulting overhead remains constant, but the coverage provided by the automatic prefaulting will vary with the underlying page size. Yes, I think what we might actually want is what I mentioned in person at BSDCan: some sort of flag to mmap() that malloc() could use to assume that any reservations are fully used when they are reserved. This would avoid the need to wait for all pages to be dirtied before promotion provides a superpage mapping and would avoid demotions while still allowing the kernel to gracefully fall back to regular pages if a reservation can't be made. I agree. ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org
