| 16:14.58 | KotCzarny | hmm, battery in note7 isnt user replaceable? lol |
| 16:15.21 | KotCzarny | that would explain why recall on the whole handsets |

| 16:42.25 | KotCzarny | saw it last week |
| 16:42.37 | RST38h | Samsung's own cores are 64bit, so they come with wider cache lines |

| 19:39.25 | 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 |
| 19:41.28 | 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 |
| 19:43.39 | DocScrutinizer05 | if processes wouldn't get shifted/transferred from a small to a fat core and back, this bug would never happen |
| 19:44.21 | 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 |
| 19:45.12 | 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 |
| 19:45.17 | DocScrutinizer05 | no, the ridiculous thing is the purge_cache function determines cache width only *once* and then keeps it in a sttaic variable |
| 19:45.24 | ShadowJK | Beyond what you could do with just cpufreq |
| 19:45.31 | ShadowJK | DocScrutinizer05, yeah |
