Jun 14 14:13:04 <ant_work> I log it here for Gnutoo
Jun 14 14:13:05 <ant_work> http://git.kernel.org/cgit/utils/kernel/kexec/kexec-tools.git/commit/purgatory/Makefile?id=b4f9f8599679259a471f3430f11966c6db78ad3d
Jun 14 14:13:17 <ant_work> the strip is wrong. I'll test evening
Jun 14 22:36:42 <ant_home> hi GNUtoo-x60
Jun 14 22:37:08 <ant_home> I've pushed temporary here
Jun 14 22:37:10 <ant_home> https://github.com/andrea-adami/meta-initramfs
Jun 14 22:37:59 <ant_home> there are many underlying issues..I'm discussing in #klibc
Jun 14 22:38:20 <ant_home> s/discussing/learning
Jun 14 22:38:21 <ant_home> ;)
Jun 14 22:38:45 <GNUtoo-x60> ok
Jun 14 22:40:17 <ant_home> <mirabilos> yeah that's legible ;)
Jun 14 22:40:17 <ant_home> <mirabilos> I see the problem
Jun 14 22:40:18 <ant_home> <mirabilos> btw do _not_ pass -Os for klibc
Jun 14 22:40:18 <ant_home> <mirabilos> not passing any -O at all will do at *least* -Os and maybe even better
Jun 14 22:40:18 <ant_home> <mirabilos> it uses "-e  purgatory_start"
Jun 14 22:40:18 <ant_home> <mirabilos> so it's a broken binary, one that cannot work with klibc because it initialises of its own
Jun 14 22:40:20 <ant_home> <mirabilos> it uses -nostdlib anyway
Jun 14 22:40:22 <ant_home> <mirabilos> so you shouldn't need to use klibc on it, you can just continue to use gcc -nostdlib -e …
Jun 14 22:40:24 <ant_home> <mirabilos> it's probably a bootloader binary blob or something like that, not a unix c programme
Jun 14 22:40:26 <ant_home> <mirabilos>    bin/bin-to-hex purgatory < purgatory/purgatory.ro > kexec/purgatory.c
Jun 14 22:40:27 <GNUtoo-x60> ok
Jun 14 22:40:28 <ant_home> <mirabilos> yeah…
Jun 14 22:40:30 <ant_home> <mirabilos> it's "data payload"
Jun 14 22:40:32 <ant_home> <mirabilos> also make sure to *not* use klcc for purgatory/*.o
Jun 14 22:40:34 <ant_home> <mirabilos> also make sure to *not* use klcc for purgatory/*.o
Jun 14 22:40:36 <ant_home> <mirabilos> for CC too
Jun 14 22:40:40 <ant_home> <mirabilos> for .c -> .o that is
Jun 14 22:40:42 <ant_home> <mirabilos> stuff like -o purgatory/purgatory.o purgatory/purgatory.c
Jun 14 22:40:44 <ant_home> <mirabilos> that cannot work with klcc because it's not targetting unix
Jun 14 22:40:46 <ant_home> <mirabilos> hm I probably need to adopt dietlibc's hack to prevent that…
Jun 14 22:40:48 <ant_home> <mirabilos> just do NOT use klcc for it
Jun 14 22:40:50 <ant_home> <ant_home> see, it was all ok until 2.0.2 .. the binaries even working (the kexec part)
Jun 14 22:40:52 <ant_home> <ant_home> │*kexec           │  84448│Jun 14 23:30
Jun 14 22:40:54 <ant_home> <mirabilos> just stop overriding CC for purgatory
Jun 14 22:40:56 <ant_home> <mirabilos> only override it for things that actually run as unix userspace
Jun 14 22:41:23 <ant_home> log I get is  http://sprunge.us/GCZT
Jun 14 22:55:05 <GNUtoo-x60> ok
Jun 14 22:55:28 <GNUtoo-x60> ah ok
Jun 14 22:55:38 <GNUtoo-x60> that sounds easier
Jun 14 22:55:49 <GNUtoo-x60> usually gcc without -shared or such thing
Jun 14 22:55:56 <GNUtoo-x60> expects a main
Jun 14 22:56:09 <GNUtoo-x60> so just put the right option to make a .o
Jun 14 22:56:14 <GNUtoo-x60> maybe -static?
Jun 14 22:56:37 <GNUtoo-x60> I don't know well what purgatory means
Jun 14 22:56:42 <GNUtoo-x60> if it has a special gcc meaning
Jun 14 22:56:48 <GNUtoo-x60> like crt.0
Jun 14 22:56:51 <GNUtoo-x60> or something like that
Jun 14 22:56:57 <GNUtoo-x60> I don't remember the exact name
Jun 14 23:02:33 <ant_home> anyway that purgatory_patch is noy yet ok
Jun 14 23:02:47 <ant_home> I'll retry letting only LD
Jun 14 23:03:03 <ant_home> btw, in the log ^^
Jun 14 23:03:06 <ant_home> gcc   -isystem/oe/oe-core/build/tmp-eglibc/sysroots/i686-linux/usr/include -O2 -pipe -o bin/bin-to-hex util/bin-to-hex.c
Jun 14 23:03:10 <ant_home> gcc ?
Jun 14 23:04:13 <GNUtoo-x60> hmmm
Jun 14 23:04:29 <GNUtoo-x60> the lack of main is because you don't ask gcc the proper format
Jun 14 23:04:37 <GNUtoo-x60> just try to fix that because it's easy
Jun 14 23:05:54 <GNUtoo-x60> I don't remember how to create .o
Jun 14 23:06:02 <GNUtoo-x60> which are objects
Jun 14 23:06:19 <GNUtoo-x60> and I must go to bed soon
Jun 14 23:06:23 <GNUtoo-x60> sorry
Jun 14 23:06:52 <ant_home> I have a feet in the shower...
Jun 14 23:07:00 <ant_home> cu
Jun 14 23:07:25 <GNUtoo-x60> ok
Jun 14 23:07:35 <GNUtoo-x60> anyway articles presenting the ELF format should have that info
Jun 14 23:07:54 <ant_home> evil ninary, isn't?
Jun 14 23:07:58 <ant_home> *binary
Jun 14 23:08:16 <GNUtoo-x60> why evil?
Jun 14 23:08:33 <GNUtoo-x60> elf has various sub-formats
Jun 14 23:08:36 <GNUtoo-x60> like the .so
Jun 14 23:08:38 <GNUtoo-x60> the .o
Jun 14 23:08:41 <GNUtoo-x60> the executable
Jun 14 23:08:43 <GNUtoo-x60> and so on
Jun 14 23:09:22 <ant_home> I mean kexec(purgatory)
Jun 14 23:09:40 <ant_home> with one side in userspace and the other in kernel
Jun 14 23:09:45 <ant_home> see this
Jun 14 23:09:47 <ant_home> http://lists.infradead.org/pipermail/kexec/2013-June/009166.html
Jun 14 23:10:38 <GNUtoo-x60> ok
Jun 14 23:10:52 <ant_home> imagine...
Jun 14 23:11:19 <ant_home> I've never used the crash/kdump part
Jun 14 23:11:58 <ant_home> I ahve only tested the kexec part w/out caring about the other kernel loaded in memory
Jun 14 23:14:24 <GNUtoo-x60> hmmm
Jun 14 23:14:30 <GNUtoo-x60> yes
Jun 14 23:14:38 <GNUtoo-x60> maybe I should try crash/kdump
Jun 14 23:14:55 <GNUtoo-x60> because I've a problem with my T60 laptop
Jun 14 23:15:07 <GNUtoo-x60> no serial yet
Jun 14 23:15:14 <GNUtoo-x60> and no logs on usb-serial
Jun 14 23:15:31 <GNUtoo-x60> and USB debug is already gone once booted
Jun 14 23:15:39 <GNUtoo-x60> and the problem appears once fully booted
Jun 14 23:18:24 <GNUtoo-x60> http://www.linuxjournal.com/googlesearch?s=ELF
Jun 14 23:18:28 <GNUtoo-x60> it has the articles on ELF
Jun 14 23:18:37 <GNUtoo-x60> I must find the good one
Jun 14 23:19:24 <GNUtoo-x60> use -c
Jun 14 23:19:29 <GNUtoo-x60> try that
Jun 14 23:20:52 <GNUtoo-x60> from http://www.linuxjournal.com/article/1060
Jun 14 23:27:26 <GNUtoo-x60> the explanation of -c is also in man gcc and matches
Jun 14 23:34:21 <ant_home> I've some little progress
Jun 14 23:34:25 <ant_home> pushed a commit
Jun 14 23:34:44 <GNUtoo-x60> ok
Jun 14 23:34:49 <GNUtoo-x60> I'll switch computer
Jun 14 23:39:32 <ant_home> now it is this
Jun 14 23:39:34 <ant_home> http://sprunge.us/IKFU
Jun 14 23:40:30 <GNUtoo-T60> ok, the main error was fixed, good
Jun 14 23:40:34 <ant_home> I have to fix the missing prototypes
Jun 14 23:40:38 <GNUtoo-T60> yes
Jun 14 23:40:47 <ant_home> still
Jun 14 23:40:50 <ant_home>  cannot find entry symbol purgatory_start; defaulting to 00000000
Jun 14 23:40:54 <ant_home> is scary :/
Jun 14 23:40:57 <GNUtoo-T60> ah ok
Jun 14 23:41:06 <ant_home> iirc it's an x86 stuff
Jun 14 23:41:25 <GNUtoo-T60> ok
Jun 14 23:41:35 <ant_home> I'll follow tomorrow
Jun 14 23:41:41 <ant_home> too late now
Jun 14 23:41:53 <ant_home> gn
Jun 14 23:42:43 <GNUtoo-T60> http://buildlogs.pld-linux.org/index.php?dist=th&arch=ppc&ok=1&name=kexec-tools&id=5618d124-83b0-422d-8ac2-8a87997d0e32
Jun 14 23:42:49 <GNUtoo-T60> seem normal....
Jun 14 23:42:55 <GNUtoo-T60> ok, good night
Jun 14 23:43:00 <GNUtoo-T60> ouch it's 01:42
