Palihm?13:38
freemangordonkernel doesn;t seem to boot in qemu13:38
Palifreemangordon: are you using my git tree?13:39
freemangordonyes13:39
freemangordonhmm13:40
freemangordonseems it was save_atags() that made it hang13:40
freemangordonafter commenting it, the kernel booted13:40
freemangordonPali: wait, why I have data in proc/atags?13:41

freemangordonPali: seems to work :)13:57
Paliok :-)13:58
freemangordonPali: http://pastebin.com/E8vJijki14:00
freemangordonPali: and http://pastebin.com/wmaGZ91h14:01
freemangordonnow I only need to figure out how to include kernel/atags.h and I'll send a patch14:02
Palifreemangordon: you need to also send 5a4a299f59b17bc6dc694865e1d007abfe211e7a14:03
*** zGrr has quit IRC14:04
*** florian has joined #maemo14:04
freemangordonPali: what about moving atags.h to include/asm?14:13
Palifreemangordon: rather ask these questions on ML14:16
PaliI'm really not somebody who can decide14:16
freemangordonI was thinking whether you want to send those patches14:17
freemangordonthe problem is that I've never sent patch series14:17
freemangordonnot sure how to do it, will need to google a lot before doing it14:18
*** Rinux has joined #maemo14:37
freemangordonPali: ^^^14:51
freemangordonPali: and what about /proc/cpuinfo?14:52
Palifreemangordon: just do git format-patch and send it14:52
Palisame as sending one patch14:52
*** Rinux has quit IRC14:52
freemangordonbut I need to send 3 patches14:53
freemangordonanyway, will look at docs how to do it14:53
Pali/proc/cpuinfo is semi-fixed14:53
Paliproblem with name is fixed in upstream14:53
Palimissing part not in upstream is revision number14:53
freemangordonit is in ATAGS?14:54
Palithis is [PATCH 1/5] and [PATCH 2/5] in that big stream :-)14:54
Paliyes it is in ATAGs14:54
Palibut I understood that those 2 patches will be accepted14:54
Palijust patch [PATCH 1/5] needs documentation14:54
freemangordonbut I guess you need to send anothe series with patch 5/5 dropped14:55
Palialso drop 4/514:55
Paliand move 3/5 into your patches :-)14:55
freemangordonah, yes14:55
freemangordonyes, I'll fix that one too14:56
Paliso just 1/5 and 2/514:56
freemangordonok, lets see if it boots with linux 4.4 :)14:56
Palianyway, if you have time you can try to write documentation for 1/5 and 2/5 patches14:56
freemangordonnever did any DT doc so far :)14:57
Palidocumentation for "/revision" DT entry14:57
freemangordonhmm - "mmc0: error -22 whilst initialising SDIO card" with upstream 4.414:58
freemangordondammit, is it possible sometimes new releases to not break what is already working :(14:59
*** at1as has joined #maemo15:09
Palifreemangordon: sd card is broken in qemu or kernel for a long time15:10
Palispecial patch is in my tree15:10
freemangordongreat15:10
freemangordonok, save_atags() work in upstream too15:11
freemangordongoing to send the patches15:11
Palifirst it try SDIO which fails with -22 and then try MMC which success15:11
Paliok15:11

*** louisdk has quit IRC15:46
freemangordonPali: how to format the "cover letter"?15:47
freemangordonI know about --compose, but what about diffstat etc15:47
Paligit format-patch --cover-letter15:47
freemangordonoh :)15:47
freemangordonPali: shold I edit it by hand?15:49
Paliyes, generate all patches with --cover-letter and then edit it15:49
Paliyou can also edit patch files if you need15:49
freemangordonok, finally the patch series seems ok :)15:52
freemangordonPali: get_maintainer spit about 15 people, shall I cc them all?15:54
Palisend email to people who are marged as maintainers15:55
Paliand to mailing lists15:55
Paliand ideally also to people active in current discussion!15:56
freemangordonok15:56
freemangordonPali: done16:01
*** louisdk has joined #maemo16:01
*** louisdk has quit IRC16:01
freemangordonwait, what happened with the last patch?16:02
*** Kabouik has quit IRC16:03
freemangordonah, it is there :016:03
Paliall patches are there16:04
freemangordonyeah, the last one came later here16:05
Palifreemangordon: for future, when you have commits which moving files, generate diffs with param -M16:05
Pali-M detect moved files and so generate smaller and more readable diffs16:05
freemangordonyou mean a parameter to format-patch?16:06
Palibut diff generation is slower! so this is reason why is not -M enabled by default16:06
Paliyes16:06
freemangordonok16:06
freemangordonhope to remember it16:06
Palialso git diff -M16:06
freemangordonI use git-gui for commits16:06
freemangordonmaybe there is an option16:06
Palievery git command which show diff should accept -M param16:06
freemangordonhmm, "additional diff parameters" :)16:07
Pali-M is running in some O(n^2) time where n is number possible renamed files16:08
Paliso for big diffs on lot of files it is sloow16:08
freemangordonso be it, I dun't ususally change lots of files before making a commit16:08
freemangordon*don't usually16:08
stryngsPali: Are ya'll talking new KP stuff? =)16:09
Palihm... what?16:09
stryngsKernel16:10
stryngsYou're "the kernel" person =)16:10
stryngsI see you talking, and I'm like, hmmm... What's Pali cookin up16:10

*** troulouliou_div2 has quit IRC16:11
bencoh:)16:12
bencohdo you think it will be included ?16:12
freemangordonyes16:13
freemangordonthe only possible proble is moving that header16:14
*** jon_y has quit IRC16:14
bencohyeah16:14
bencohprecisely16:14
freemangordonbut if they reject it, they should provide a solution16:14
freemangordonso the worst that can happen is /me re-sending the series again16:14
bencoh:)16:15
bencohPali: is elinux.org accurate/up-to-date by the way?16:15
freemangordonbut having in mind that this ATAGS problem persist for ~2 years, this is more than acceptable16:15
Palihttp://elinux.org/N900 should be up-to-date16:16
Palianyway, do you know POSIX way how to get all ipv6 addresses assigned to network adapter?16:18
Paliin linux we have getifaddrs() function16:18
Palibut it is not portable16:18
buZzwhich maemo version isnt based on linux?16:19
Palithis is not for maemo, general network question :-)16:19
bencohgetifaddrs exists on osx16:20
bencohwell, the man page at least. and the man says "BSD"16:20
bencohI have it on freebsd as well (in /usr/include/ifaddrs.h)16:20
bencohsame on openbsd16:21
bencohit doesnt look too bad16:21
bencohstructure definition seems pretty similar too (apart from the union on linux)16:22
bencohlooks like a pretty sane choice16:24
Palihm... I just need to get link-local address of adapter16:32
Paliis not there something better as enumerarate all network interfaces via getifaddrs()?16:33
bencohhmm, I think there is, lemme check16:37
bencohnevermind, the example I had in mind for network adapters used ... netlink16:41
bencohdefinitely not portable16:41

freemangordonPali: are you going to resend your patches, without what I've already send?18:55
Palifreemangordon: after your (new) patches will be accepted18:55
freemangordonPali: also, don;t count on me re DT docs, I don;t really know where to start from neither what am I supposed to write in :)18:56
freemangordonok18:56
Paliok18:56
freemangordonBTW I think you can send driver patches without docs18:57
freemangordonor rather - docs can follow-up18:57
freemangordonDT that is18:57
PaliPATCH 1/5 just needs documentation what is "/revision"18:59
Palieverything other (driver parts) are done18:59
freemangordoniiuc, you only need to resend 1/5 and 2/519:01
