ppisatijanimo: ping08:18
ppisatijanimo: where's the git tree for the nexus7 kernel? are you mantining it, right?08:18

ppisatiargh08:19
ppisati...08:19
lilstevieppisati, https://wiki.ubuntu.com/Nexus7/SourceCode08:23
ppisatililstevie: cool, thanks08:23
lilstevienp08:26
janimoppisati, we should shortlyh decide at UDS where to place it so it can be comaintained08:28
ppisatijanimo: ack, iirc there was a session about it08:28
janimoppisati, right. Looking for something specific or just checking it out?08:29
janimoI have a few more power related commits that are not yet pushed out08:29
ppisatijanimo: just checking it out08:29
janimook08:29
lilsteviejanimo, I was just looking briefly at what you have done, what else does the battery driver have that it can export08:30
janimolilstevie, I just received a patch yesterday about that. I'll push it out shortly08:32
lilstevieok cool, the few patches I have tried to get them exposed with the tf101/tf201 just break the driver :(08:36

steevis it possible to install a softfloat compiler on precise (on arm)? to build e.g. a kernel?19:57
steevarmhf*19:57
xranby_ac100steev: basically you pass -mfloat-abi=softfp to gcc when building your kernel20:01
xranby_ac100export CFLAGS="-mfloat-abi=softfp"20:01
xranby_ac100export CXXFLAGS="-mfloat-abi=softfp"20:01
xranby_ac100shoudl do it20:01
infinityxranby_ac100: Uhm.  The kernel doesn't need any such thing done.20:05
xranby_ac100infinity: you are right ..20:05
infinitysteev: Compiling kernels should Just Work, regardless.20:05
xranby_ac100steev: the kernel interface is the same for softfloat and hardfloat (the kernel do not use any userspace system librarys)20:06
steevyeah, you're right, except there's a minor issue with the 4.6 compiler and hardfloat, so i'd prefer to tell it to use softfloat, or use a softfloat compiler20:19
steevhttp://gcc.gnu.org/bugzilla/show_bug.cgi?id=5244520:19
ubot2gcc.gnu.org bug 52445 in tree-optimization "[4.6 Regression] conditional store replacement causes segfault in generated code" [Normal,Assigned]20:19
xranby_ac100infinity: btw.. are you at uds right now?20:23
infinityxranby_ac100: Aye.20:23
xranby_ac100in the testcase writing seminar?20:23
infinityxranby_ac100: Nope.20:24
xranby_ac100ok well see you around.. i am at the testcase hackatron right now20:24
infinitysteev: Hrm.  That bug doesn't seem to imply it's HF-only (or even ARM-only).  We can definitely look at backporting the fix to precise, though.20:27
steevinfinity: you're right, i was going from experience with gentoo which has the issue only with hf compiler (4.6.3)20:28
steevi have a bug open on the gentoo end, but sadly, i can't seem to build a debian package of the kernel on my gentoo box20:29
infinitysteev: doko's got a precise SRU for gcc-4.6 pending, I'll ask him to add this backport.  Can you file a launchpad bug for reference?20:31
steevinfinity: i would prefer not to - launchpad loves to spam me with bugmails.  i still get mails from a bug that was opened in 200520:31
infinityUnsubscribe from it, if it's still getting comments?20:32
infinitysteev: Anyhow, you could also just build your kernels with gcc-4.7 in a quantal chroot, they'll install just fine on precise.20:33
GrueMasterIf you are the filer, you can't unsubscribe.  I've tried.20:33
infinityGrueMaster: Oh, fair point.20:33
steevinfinity: heh, actually, it's for maverick20:33
* infinity filters all his bug mail anyway, so doesn't really notice or care.20:33
steevbut yeah, the arm box doesn't really have enough space to add a quantal chroot20:33
infinitysteev: I'll poke doko later about adding PR52445 to his precise SRU.  We'll need someone to open a bug for tracking/validating it, though. :/20:34
* steev points at GrueMaster20:34
steevi'll be more than willing to test it, but no, i'm sorry but i refuse to use launchpad20:35
infinitysteev: Do you know which driver(s) get miscompiled?  The upstream bug is vague.20:35
GrueMasterMy only real complaint is that a lot of the bugs I filed got ignored until I was no longer doing arm work.  Then suddently there appeared to be fixes for me to test, but they were reverted because I no longer do testing.20:39
steevoff the top of my head the flexcan driver, but if you search gcc 4.6.3 miscompiling arm-linux20:40
steevthere's a long thread on lakml20:40
steevGrueMaster: ditto, except i'm still doing arm - and more specifically, bugs were filed with patches that were ignored until irrelevant20:40
steevand by irrelevant, i mean we're no longer using that software because we've forked it because we couldn't wait for the fixes to be added20:41
GrueMasterYep.20:41
steevit's not a whole lot, but when you appear to not maintain the software, users and developers really develop a distate20:41
steevand no offense, but if i've already done the work, and provided a patch, i don't really see why i should also have to pay canonical to get it applied20:43
infinitysteev: Who's asking you to pay to get pathes applied?20:43
infinityOr patches.20:43
steevno one, directly20:44
infinityI realise it's frustrating to not have every bug addressed, but hyperbole doesn't help.20:44
infinity(For the record, of all the bugs I've fixed over the years in Ubuntu, exactly one of them was escalated from a paid customer, and it was a bug that I was working on upstream regardless)20:45
