| KotCzarny | does samsung produce its own batteries? | 19:06 |
| KotCzarny | also, fuckups happen | 19:07 |

| KotCzarny | some random comment: From 24 Million few Handsets went to an explosion! and samsung investigated on it and found few batches got battery from a local vendor! the quality of the battery pack! (the battery is maid by samsung! just the protecting cover!! is faulty) | 19:11 |
| KotCzarny | hmm, battery in note7 isnt user replaceable? lol | 19:14 |
| KotCzarny | that would explain why recall on the whole handsets | 19:15 |
| kerio | handsets should do what the nintendo 3ds does | 19:16 |
| kerio | and have a user replaceable battery behind a screwed-in panel | 19:16 |
| KotCzarny | https://imgur.com/a/RMBnv | 19:16 |
| RST38h | Kot: They made it unreplaceable starting with Note 5 | 19:36 |
| RST38h | Kot: At Note 7, karma finally caught up with them | 19:36 |
| KotCzarny | exactly | 19:36 |
| RST38h | And in such an ironic way, hehe... | 19:36 |
| KotCzarny | do you think it was apple's sabotage? | 19:37 |
| RST38h | I think it was karmic justice. | 19:38 |
| RST38h | Hopefully they will pay for replacing 1+ million Note7s and learn to make battery replaceable again in Note8 | 19:38 |
| KotCzarny | or just make design/testing/postproduction-testing better | 19:40 |
| RST38h | Can't account for every fuckup, better have plans B, C, etc | 19:41 |
| KotCzarny | my n900 didnt 'sploded yet | 19:41 |

| RST38h | http://www.theregister.co.uk/2016/09/13/arm_biglittle_gcc_bug | 19:41 |
| KotCzarny | not going to change that | 19:41 |
| KotCzarny | cache linesizes? | 19:41 |
| KotCzarny | or something new? | 19:42 |
| RST38h | Yep | 19:42 |
| KotCzarny | saw it last week | 19:42 |
| RST38h | Samsung's own cores are 64bit, so they come with wider cache lines | 19:42 |
| KotCzarny | but its new thing, so as always, assumptions will fail sooner or later | 19:42 |

| DocScrutinizer05 | ridiculous how they try to optimiue by determining I-cache width only once.

| ShadowJK_ | They don't do "transitions" anymore really, all cores can be active at same time | 21:14 |
| ShadowJK_ | So what you have is not SMP, but asymmetric multiprocessing :) | 21:14 |
| KotCzarny | :) | 21:14 |
| ShadowJK_ | There are some 10-core SOCs now, where you have 4 low perf cores, 4 medium perf, and 2 high performance cores, and they can all be active at the same time | 21:15 |
| KotCzarny | but its like running something on pentium-pro, then in an instant replacing cpu with pentium-mmx | 21:15 |
| KotCzarny | ShadowJK_: are you sure they arent counting MALI cores? ;) | 21:15 |

| DocScrutinizer05 | ShadowJK: thanks a lot | 22:38 |
| DocScrutinizer05 | ShadowJK: ((They don't do "transitions" anymore)) however that's exactly where their stuff explodes, see http://www.theregister.co.uk/2016/09/13/arm_biglittle_gcc_bug | 22:39 |
| DocScrutinizer05 | they create JIT code, so they need to purge I-cache to make the code really available, and that fails since they may clear 64bytes but the cache width of new core the process got reassigned to is 128byte | 22:41 |
| DocScrutinizer05 | if processes wouldn't get shifted/transferred from a small to a fat core and back, this bug would never happen | 22:43 |
| ShadowJK | Oh, I thought you meant the old style big.little where you either had 1-4 big cores running, or 1-4 small cores running, but not both at the same time | 22:44 |
| ShadowJK | KotCzarny, who knows if it's the design of the cores itselves, or details in manufacturing, but they do supposedly run at different efficiencies | 22:45 |
| DocScrutinizer05 | no, the ridiculous thing is the purge_cache function determines cache width only *once* and then keeps it in a sttaic variable | 22:45 |
| ShadowJK | Beyond what you could do with just cpufreq | 22:45 |
| ShadowJK | DocScrutinizer05, yeah | 22:45 |
| ShadowJK | Interestingly that Helio SoC actually has an 11th CPU too :-) | 22:46 |
| DocScrutinizer05 | the sensor shite, yeah | 22:47 |
| DocScrutinizer05 | really weird how they throw mountains of etched silicon at such a relatively simple task like operating a smartphone | 22:48 |
| ShadowJK | My current daily phone has 4 cores and I find I could use more ;-) | 22:48 |
| DocScrutinizer05 | instead of maybe decently isolating the modem, to start with | 22:48 |
| DocScrutinizer05 | pastebin top with 4 running processes or it didn't happen ;-) | 22:49 |
| ShadowJK | It's mostly like open tab 1, 2, 3, 4, 5, 6 in browser, go to tab 1 and wait for it to load and hope the other ones have loaded before I'm done reading | 22:50 |
| DocScrutinizer05 | heck, even on my PC I hardly get all 4 cores (8 virtual) busy with concurrent processes | 22:50 |
