| 03:20.36 | detule | wife is learning C for work ... finally i can show off my skillz |
| 03:21.21 | jonpry | hi detule |
| 03:22.49 | detule | hey jonpry that 3.0 kernel the touchpad is running on - does it have that peripheral loading interface |
| 03:23.00 | detule | nice job on that btw |
| 03:23.21 | jonpry | they call it peripheral-reset |
| 03:23.37 | jonpry | same thing as pil though |
| 03:24.17 | detule | it seems strange to me that they wouldn't secure the access on v3, but would completely lock out v4 |
| 03:24.24 | jonpry | i cooked up a webos kernel without audio and a patched reset |
| 03:24.54 | jonpry | supposedly there are some 8960 devices with unlocked dsp control |
| 03:25.08 | detule | huh? |
| 03:25.11 | jonpry | it got fixed up in february |
| 03:25.25 | jonpry | of 2012 |
| 03:25.34 | jonpry | according to the motherlode |
| 03:25.36 | detule | oh so whatever was out before that? |
| 03:25.43 | detule | which was what, nothing |
| 03:25.49 | jonpry | probably |
| 03:28.29 | detule | front camera is working on 3.4....well, records video, streams, face lock/unlock....but it doesn't snap photos.... |

| 03:29.30 | detule | dies trying to do some sort of wavelet denoising or some other qcom proprietary postprocessing crap that doesn't output any error to klog |
| 03:29.48 | jonpry | hmm |
| 03:29.56 | jonpry | can you turn it off? |
| 03:30.23 | detule | well, if i knew whether that daemon reads some sys prop or takes its queues from somewhere |
| 03:31.46 | jonpry | sounds like progress anyways |
| 03:32.57 | jonpry | i wonder what takes care of that |
| 03:33.09 | jonpry | vfe or maybe that daytona thing |
| 03:33.58 | detule | they have some other devices....gemini and mercury offline jpeg encoder/decoder....not sure if they get called for something like this.... |
| 03:39.50 | jonpry | wavelet denoising is some real garbage |
| 03:40.33 | jonpry | i figured out some of the math on that once |
| 03:41.40 | jonpry | it's kind of like making picture look prettier with little regard for what the picture is actually of |
| 03:43.09 | detule | yeah i've seen a few talks about...what cool applied people do |
| 03:44.43 | jonpry | haha |
| 03:45.17 | jonpry | i think in this case it's really not so good |
| 03:45.26 | jonpry | like gloss screens |
| 03:46.28 | detule | i don't get why something like that wouldn't be handled in userland |
| 03:51.33 | jonpry | so they can hide the code |
| 03:51.48 | jonpry | make it qcom proprietary like every other thing |
| 03:51.57 | detule | don't think that math is revolutionary |
| 03:52.23 | detule | i think what we did with that touchpad touchscreen driver was more sophisticated |
| 03:53.07 | detule | ...and less functional |
| 03:53.23 | jonpry | wavelet denoising is a tad more involved |
| 03:53.32 | jonpry | but it's similar |
| 03:53.58 | jonpry | ends up being an optimization problem |
| 03:55.14 | jonpry | there's some kind of matrix they want to invert. but it's super ilconditioned so the wavelet is used as an objective function |
| 04:11.41 | ali1234 | yes, wavelets are just another way of optimizing convolutions, like FFT, but with different math. |
| 04:13.24 | detule | i leave math to the experts |
| 04:13.46 | jonpry | isn't that you? |
| 04:14.00 | detule | sh |
| 04:14.47 | jonpry | i've been trying to compile glibc for hexagon for some hours now |
| 04:15.54 | detule | that linas fellow would come in handy right about now |
| 04:16.08 | jonpry | yeah he would |
| 04:16.12 | jonpry | all this stuff is broke |
| 04:16.20 | detule | you using these patches https://www.codeaurora.org/patches/quic/hexagon/dev/ ? |
| 04:16.28 | jonpry | compiler segfaults. doesn't support things |
| 04:17.45 | jonpry | i'm using the 4.0 compiler |
| 04:17.51 | jonpry | and the dev glibc patches |
| 04:18.05 | jonpry | which is maybe part of the problem |

| 04:48.46 | detule | well we're running broadcom drivers |

| 05:09.37 | jonpry | 0x032040A0 |
| 05:09.43 | jonpry | should be the boot address |
| 05:10.33 | jonpry | only the lower 16bits should be writable |

| 05:15.23 | jonpry | i figure there is some kind of external amplifier that your device doesn't have |
| 05:16.03 | detule | we'll chalk this up on the "x" between the "8" and the "6" |
