09:33 < rxr> michael-i: great
09:35 < michael-i> and uclibc now doesn't flub up my build thanks to the r24201 scsi header conflict patch
09:36 < michael-i> rxr: we'll get a mail to you today about wrapping things up
09:37 < rxr> michael-i: :-)

09:45 < mpp> :-)
09:56 < mpp> hey rxr
09:56 < mpp> could need some help on linux26 kernel
09:56 < rxr> update ?
09:56 < mpp> i need to have more than 8 cpu's
09:57 < mpp> any clue where this might be in the config ..
09:57 < rxr> MAX_CPU*
09:57 < mpp> mom
09:58 < rxr> # grep NR_CPU /boot/kconfig_2.6.2*
09:58 < rxr> NR_CPU it is
09:58 < rxr> default to 8 in the linux kernel kconfig I guess :-)
09:58 < rxr> (for x86, for ARM et.al it's a different matter anyway ...)
09:58 < mpp> for x86_64 i need it
09:59 < mpp> k found it in the source tree
10:00 < mpp> NR_CPUS=64
10:01 < mpp> at least thats what the source tree has
10:03 < mpp> the kconfig after building has CONFIG_NR_CPUS=8
10:06 < rxr> the x86 defconfig might have another value
10:06 < rxr> or the Kconfig file another default
10:06 < rxr> we do not set it in the t2 architecture configs
10:07 < rxr> how many cpus did you got there ?
10:07 < rxr> ok - interesting the x86 defconfigs have
10:07 < rxr> configs/x86_64_defconfig:CONFIG_NR_CPUS=64
10:07 < rxr> configs/i386_defconfig:CONFIG_NR_CPUS=64
10:08 < rxr> I just noticed with the rename of the defconfigs we might no longer merge them in the t2 auto-config
10:08 < rxr> in the x86 Kconfig the default lives:
10:08 < rxr> config NR_CPUS
10:08 < rxr> int "Maximum number of CPUs (2-512)" if !MAXSMP
10:08 < rxr> range 2 512
10:08 < rxr> depends on SMP
10:08 < rxr> default "4096" if MAXSMP
10:08 < rxr> default "32" if X86_NUMAQ || X86_SUMMIT || X86_BIGSMP || X86_ES7000
10:08 < rxr> default "8"
10:11 < mpp> right . i digged into this some months ago
10:12 < mpp> how do i patch the default value for the t2-build process to be clean/sane
10:12 < rxr> I would not patch it
10:12 < rxr> I would add a kernel config file to your target
10:12 < rxr> target/desktop/kernel.conf
10:12 < rxr> just add a CONFIG_NR_CPUS=128 (or what you need) in there
10:13 < rxr> I'm curious, how many CPUs do you have?
10:13 < mpp> ahm 16
10:13 < mpp> and more to come
10:13 < rxr> neat
10:13 < mpp> yes 4 quadcore xeon 72xx
10:13 < rxr> you can not accidently share some VM account for t2 building ? :-)
10:13 < mpp> sorry these are cusomer machines...
10:13 < rxr> :-(
10:14 < mpp> i would do so right away if had them
10:14 < mpp> for my own purpose
10:14 < mpp> that's okay
10:14 < rxr> ok - our 8-core is not too shabby, just the KVM virtualizer layer needs and update to squeeze some more performance out of it
10:14 < mpp> i am already using some multicore systems with 4 or more cores dedicated to build t2
10:16 < mpp> rebuilding test kernel now
10:17 < mpp> ill report back..
10:17 < mpp> thanx in advance
10:17 < mpp> :-)
10:18 < rxr> you're welcome

10:26 < mpp> hm...
10:29 < rxr> hm?
10:29 < mpp> just thinking out loud
10:29 < mpp> okay nr_cpus is set right now
10:30 < mpp> so lets see how many peng's the boot screen shows ... :-)
10:30 < mpp> i was also wondering if the x86_64 kernel has memory limits ...
10:31 < mpp> 16 cores and 128gig ram is common here....
10:40 < rxr> limit as per Kconfig snipplet above is 512 or 1024 (depending on MAXSMP)
10:51 -!- mqueiros_ [n=mqueiros@217.70.71.43] has joined #t2
11:07 < mpp> well the 16core kernel crashed in the boot phase
11:24 < mpp> hey rxr - just a reminder about hg repos ....
11:27 < rxr> well, yeah - lars 4th child was just born and I'm actually even a little more busy then usual ... guess it has to wait some more days :-(
11:30 < mpp> no prob
11:30 < mpp> 16core kernel now boots fine
11:30 < mpp> htop is fun
11:30 < mpp> looks like a sound equalizer :-)
11:30 < mpp> 16 bars ....
11:37 < rxr> lucky you
11:41 < mpp> nah - like i said it's customers box
11:42 < mpp> only have have it here for a couple of days
11:42 < mpp> but it's fun i admit
11:45 < rxr> I guess it's 19" xHE and quite noisy ?
11:47 < mpp> yes
11:48 < mpp> but the powermanagement reduces the noise to a very reasonable level
11:48 < mpp> considering the hp it has to offer
11:48 < michael-i> I have a package which needs headers from another package while building. What is the best way to automate their inclusion before and removal after the build?
11:49 < rxr> just select as normally and just don't include it in your final system deployment
11:52 < michael-i> My problem with that is, the package which my package needs, depends on linux26 which cannot currently be built. I was thinking I could use pkg_asterisk_pre.conf to extract the dahdi drivers source before building asterisk?
11:54 < rxr> if you just needs the headers, maybe tweak this currently failing package to just copy the headers for now ?
11:55 < michael-i> That sounds better...I'll make a dahdi-headers package following the linux-headers example and make sure it has a higher build priority.
11:56 < rxr> I would use the dahdi package (without -header)
11:56 < rxr> and let it just install the headers
11:57 < michael-i> because they'll conflict later....gotcha

14:03 < CIA-41> rene * r32737 /trunk/package/shells/mc/mc.cache: * removed mc-mp from mc.cache
14:28 < michael-i> It seems as though the build priority of a package cannot be overridden via a target package definition?
14:29 < rxr> hm - that might be the case
14:29 < rxr> which package do you wanna alter?
14:29 < rxr> maybe we can just commit that to trunk anyway ?
14:30 < michael-i> i can just move the other packages to a lower number (those which aren't currently in t2 at all)
14:30 < michael-i> when they're finally ready, all will be ok
14:34 < CIA-41> rene * r32738 /trunk/package/lua/lua-lanes/ (. lua-lanes.cache lua-lanes.conf lua-lanes.desc): * added lua-lanes (2.0.3) - Multithreading in Lua
