[10:04:08] <jepler> seb_kuzminsky: can you add more words on the front page of http://buildbot.linuxcnc.org/ so that it doesn't imply you can get the amd64 + preempt-rt + jessie combination right now?
[10:13:34] <linuxcnc-build> build #1345 of 4018.deb-wheezy-rtai-i386 is complete: Failure [4failed shell_1] Build details are at http://buildbot.linuxcnc.org/buildbot/builders/4018.deb-wheezy-rtai-i386/builds/1345 blamelist: Jeff Epler <jepler@unpythonic.net>, andypugh <andy@bodgesoc.org>, John Thornton <bjt128@gmail.com>
[10:51:54] <seb_kuzminsky> jepler: will do
[11:01:36] <seb_kuzminsky> done
[11:14:50] <seb_kuzminsky> i think it'd be a smop to adapt the rtai kernel building infrastructure to build rt-preempt kernels
[11:15:05] <seb_kuzminsky> for nearly arbitrary versions of linux & the rt-preempt patch
[11:15:31] <seb_kuzminsky> the rtai kernel build infrastructure is based on the debian.org kernel packaging, and it includes support for rt-preempt
[11:16:16] <seb_kuzminsky> just need to pick a version of debian.org's packaging that refers to a kernel.org version that's supported by rt-preempt, then figure out how to use their machinery to get the rt-preempt patch in
[15:00:59] <jepler> seb_kuzminsky: that would be great, have any tuits?
[15:11:07] <jepler> > UEFI requires the firmware and operating system loader (or kernel) to be size-matched; for example, a 64-bit UEFI firmware implementation can load only a 64-bit operating system boot loader or kernel
[15:11:27] <jepler> huh so it may be as terrible as norbert says. I didn't know about this brokenness of UEFI
[15:12:04] <jepler> wikipedia goes on to say that 64-bit Linux can transition from 32-bit UEFI but leaves it unsaid that going the other way doesn't work
[15:12:22] <jepler> stupid stupid stupid design, if you make the mistake of thinking UEFI's goals are to boot general purpose operating systems
[15:14:08] <jepler> http://blogs.intel.com/evangelists/2015/07/22/why-cheap-systems-run-32-bit-uefi-on-x64-systems/
[15:39:26] <pcw_home> The couple UEFI implementations I've seen do have a working legacy mode so its possible to boot 32 bit OS's
[15:39:27] <pcw_home> (is there some reason to not go to 64 bit for modern dists? I guess there are still some people running PIIIs )
[16:01:29] <jepler> assuming the underlying RT kernel isn't flaky, just the usual manpower problems
[16:09:51] <cradek> a lot of post-P3 machines have no 64 bit mode. it's not that crazy to still encounter them.
[16:10:03] <cradek> I think I have xeon and celeron machines here that are that way
[16:10:25] <cradek> but yeah, they are old
[16:18:30] <pcw_home> yeah almost any x86 hardware less then 10 YO will be x86-64
[16:36:48] <pcw_home> looks like VIA didn't have a 64 bit capable CPU till 2008 or so
[19:16:03] <seb_kuzminsky> grumble, now the jessie-rtai-i386 vm is crashing too - twice today
