| 01:08.41 | dr1337 | hey guys |
| 01:08.59 | dr1337 | anyone with experience in disassembling gralloc modules? |
| 01:09.53 | phh | just ask ? :p |
| 01:10.30 | dr1337 | ? |
| 01:10.42 | phh | if you've got a question, ask |
| 01:10.59 | dr1337 | Cannot load library: reloc_library[1285]: 4158 cannot locate 'android_atomic_cmpxchg'... |
| 01:11.18 | dr1337 | I need to disassemble and hexedit the gralloc module to work with libc |
| 01:11.25 | phh | oO |
| 01:11.33 | phh | might i ask you why ? |
| 01:11.35 | phh | gralloc is opensource |
| 01:11.38 | dr1337 | ICS ;) |
| 01:12.28 | dr1337 | qsd8k from qualcomm? |
| 01:12.32 | phh | you're trying to load like GB's gralloc on ICS you mean ? |
| 01:12.37 | phh | yes |
| 01:12.37 | dr1337 | well i don't have the source for Ice Cream Sandwich yet |
| 01:12.43 | dr1337 | yes |
| 01:13.23 | phh | (your error sounds like they did some optimisation) |
| 01:14.05 | arrrghhh | oh sdk ports are fun |
| 01:14.12 | phh | dr1337: define android_atomic_cmpxchg function as asm("cmpxchg") in gralloc sources ? |
| 01:14.16 | phh | (sounds totally stupid, i know) |
| 01:14.34 | dr1337 | they probably did |
| 01:14.38 | dr1337 | just treating it out |
| 01:14.41 | dr1337 | *testing it out |
| 01:15.06 | phh | dr1337: sdk port on N1 doesn't have proper gralloc ? |
| 01:15.15 | dr1337 | nope |
| 01:15.17 | dr1337 | using the default gralloc |
| 01:15.25 | dr1337 | hence the reason why the GL is slow as hell |
| 01:15.41 | dr1337 | quite interesting |
| 01:16.01 | phh | funny, launcher didn't seem slow as helll |
| 01:16.05 | dr1337 | the stock gralloc.qsd8k.so gives me a different error from CM |
| 01:16.12 | dr1337 | oh so you've used it then? |
| 01:16.23 | phh | na |
| 01:16.30 | phh | just speaking of few videos of sdk port i've seen :p |
| 01:16.35 | dr1337 | yeah they did some optimisations |
| 01:16.43 | dr1337 | all 2D drawing is GL accelerated |
| 01:16.49 | dr1337 | but that's running on emulated opengl |
| 01:16.54 | phh | ok |
| 01:17.04 | dr1337 | so it may appear smooth, but it's all software rendering done on the CPU |
| 01:17.19 | phh | i didn't say smooth ;) |
| 01:17.35 | phh | but i'd expect emulated opengl to be really way too slow |
| 01:18.07 | dr1337 | it's actually not too bad |
| 01:18.15 | dr1337 | it's certainly faster than the emulator |
| 01:18.20 | phh | :) |
| 01:18.51 | phh | dr1337: anyway, you could static build gralloc :D |
| 01:19.08 | dr1337 | hmm i suppose i could.... |
| 01:19.19 | dr1337 | since the source is available and i have all the library so |
| 01:19.35 | phh | sounds too easy uh ? :D |
| 01:19.52 | dr1337 | it always sounds easier than reality ;) |
| 01:21.23 | arrrghhh | words are funny that way |
| 01:28.46 | dr1337 | hmm |
| 01:28.50 | dr1337 | looks like i can't do that |
| 01:28.56 | dr1337 | need the source header files |

| 01:42.39 | dr1337 | can't build it form source |
| 01:42.57 | phh | well i'm sure all what's needed to build it are available |
