| 08:03.57 | oliv3r | i think a template could be somewhat usefull to 'generate' the registers page from sub pages |
| 08:09.47 | oliv3r | omg, this HAS to be a 'bug' in the datasheet. |

| 08:14.59 | mnemoc | doesn't like the idea |
| 08:15.59 | mnemoc | for the initial content you can use an script to generate locally and paste the result |
| 08:16.35 | mnemoc | but for later maintainance using templates for that becomes a limitation |
| 08:17.06 | mnemoc | for infoboxes and banners the templates work great. but not for content |
| 08:18.42 | oliv3r | AVS_CNT1_PS (pause the audio/video sync counter) is supposed to pause, and un-pause the AVS counter. |

| 10:04.47 | afgdsgh | hello |
| 10:05.15 | afgdsgh | whats the difference between RK3066 Cortex A9 and a10 allwinner |
| 10:05.29 | afgdsgh | rk3066 is in mk808 |
| 10:05.40 | afgdsgh | and a10 allwinner in uhost (itsd mini pc tv android device) |
| 10:09.33 | Marex | afgdsgh: different manufacturer :p |

| 10:11.21 | mnemoc | zub: ----^ |
| 10:11.38 | rm | zub, wtf :s |
| 10:12.00 | afgdsgh | Marex i read that rk3066 chip is worse when decoding full hd video than a10 allwinner, how its possible if rk3066 has faster dual processor? |
| 10:12.11 | rm | zub, => http://dpaste.com/811475/ |
| 10:12.25 | rm | and it nukes the whole HID section from the config after that |

| 10:13.05 | mnemoc | rm: 3.0, right? I'll revert it now |
| 10:13.18 | rm | yes, 3.0 (next_mali if that matters?) |
| 10:13.21 | Marex | afgdsgh: you're decoding the video on coprocessor |
| 10:14.48 | afgdsgh | i meant im watching 1080p video |
| 10:15.12 | rm | with that patch reverted, make oldconfig proceeds normally |
| 10:15.14 | afgdsgh | and i read that it works better on a10 allwinner comparing it to rk3066 chip |
| 10:15.53 | mnemoc | afgdsgh: video decoding is not done by the general purpose processor, so the cortex-a9 vs cortex-a8 part doesn't affect it |
| 10:17.58 | afgdsgh | anyone of you guys tested mk808 or uhost? (mini pc android tv) |
| 10:18.24 | rm | afgdsgh, how would you even proceed installing GNU/Linux on RK3066 |

| 17:08.18 | aexl | gnexus tested it as the best ... i don't care. whatever works i guess. |
| 17:09.24 | aexl | also why do you want a kernel package without the kernel image included? |
| 17:09.37 | rm | it includes the kernel image, just not the uImage |
| 17:10.01 | aexl | is that doable? |
| 17:10.14 | rm | you mean to make it include uImage? |
| 17:10.19 | aexl | yep |
| 17:10.34 | rm | yeah, you could modify kernel-package scripts, but then there's an issue that uImage has to be called that |
| 17:10.53 | mnemoc | traeak: eh? |
| 17:10.53 | rm | and no symlinks work since this is on a FAT filesystem |
| 17:11.14 | rm | so you will get an issue of having 2 or more kernel packages conflicting |

| 17:46.05 | Turl | needs to reread the operator part on K&R |
| 17:46.14 | Marex | Turl: yep |
| 17:46.19 | Marex | it's 2, indeed |
| 17:47.03 | mnemoc | i thought 2 too.... but candide (a C evaluating bot) disagrees |

| 17:47.44 | mnemoc | 19:43:50 <candide> mnemoc: 1 |

| 17:50.20 | Turl | how is it picking 1? |
| 17:50.24 | Marex | Turl: it won't ever get there |
| 17:50.26 | mnemoc | i got used to (cond)?1:0 because "true" is != 0 |

| 17:51.01 | Marex | int fn(int arg[*]); <--- you ever saw this declaration ? :) |
| 17:51.03 | mnemoc | but I would have expected 2, not 1 |

| 17:54.26 | mnemoc | over 20 years doing C and first time I see that *ever* :) |
| 17:55.40 | Marex | mnemoc: did you ever _read_ the spec? :D |
| 17:56.08 | mnemoc | nope :p |
| 17:56.30 | Turl | what does it indicate? |
| 17:56.43 | mnemoc | probably passing an array... |
| 17:57.08 | Marex | yep, forward decl. |
| 17:58.14 | mnemoc | passing a pointer and a length is more decent :p |
| 18:00.38 | Turl | passing a pointer and terminating your stuff with a delimiter is good too :) |
| 18:02.16 | Marex | Turl: passing an array and passing a string are two different things |
| 18:02.24 | Marex | and wasting memory is not good |
| 18:02.49 | mnemoc | sentinels are expensive |

| 18:42.35 | mnemoc | for old sun4i you would use mele_a1000 target |
| 18:42.45 | mnemoc | for old sun5i, a13_olinuxino |
| 18:43.02 | wingrime | also i have bring tochscreen with my own patches |

| 18:43.27 | mnemoc | zub: grep sunxi boards.cfg for other options |
| 18:43.33 | zub | mnemoc: thx |
| 18:44.12 | aexl | mnemoc: pardon my ignorance but could i adopt the ft5x_ts patch? if i could find it? |
| 18:44.30 | mnemoc | aexl: sure |
| 18:44.40 | wingrime | it need some adoptation |
| 18:44.56 | wingrime | i do two things |

| 18:45.36 | zub | my board is mk802+... I don't see anything specific, so I'll try mele_a1000 |

| 18:47.32 | zub | I guess this ^ comes from the SPL |
| 18:47.45 | mnemoc | zub: yes |
| 18:48.18 | mnemoc | zub: it might be safer for you to "downgrade" u-boot a bit |
| 18:48.27 | zub | I had same behaviour last week when I tried. So I gave up and used a binary from some other image. |
| 18:48.32 | mnemoc | the dram/pmu changes aren't mature yet |

| 20:12.06 | hno | mnemoc, is that the time from u-boot starting kernel until kernel starts talking? |
| 20:12.13 | mnemoc | hno: doesn't the PMU take care of making the clock transition safely? |
| 20:12.15 | hno | Turl, I know. |
| 20:12.42 | hno | mnemoc, the PMU manages voltages, not clocks. |

| 20:35.50 | hno | Turl, looks like your code is looping over APB divisor settings when changing frequency. Old code just sets transition divisor, PLL1, target divisor. |

| 20:39.08 | hno | 1. Set transition APB divisor. |
| 20:39.09 | rz2k | did you base ram settings on my script bin from nanda that I supplied or from ones available at mnemoc's script.bin archive? because my mele is actually a2000 v1.6, I dont really know, but wouldnt these settings vary per model/rev, e.g. different ram installed. |

| 20:41.18 | Turl | you run the first if block |
| 20:41.35 | Turl | when you're out of it your old freq pll is now 20400000, and new freq is still smaller |
| 20:41.40 | Turl | you run the 2nd if |
| 20:41.45 | Turl | etc |
| 20:41.48 | hno | But I see now that I was looking at an early version of your code. |
| 20:42.36 | Turl | :) |
| 20:43.00 | hno | No, you still have that loop. |
| 20:44.08 | Turl | which loop are you refering to? |
| 20:44.15 | hno | https://github.com/allwinner-dev-team/linux-allwinner/blob/wip/allwinner-3.0/cpufreq/arch/arm/mach-sun4i/cpu-freq/cpu-freq.c#L211 |
| 20:44.50 | Turl | hno: that loop simulates the cascading ifs on the old code |

| 20:47.11 | zub | (took a while, as at first I was trying to edit the env, then gave up and nuked it...) |
| 20:47.52 | hno | Turl, or even https://github.com/amery/linux-allwinner/blob/allwinner-v3.0-android-v2/arch/arm/mach-sun4i/cpu-freq/cpu-freq.c#L247 to illustrate it more. |
| 20:48.06 | Turl | hno: what's with it? |
| 20:52.27 | Turl | hno: I don't see the point you're trying to make :( |
| 20:53.27 | hno | Assume old freq is 60MHz(1:1:1:2). New freq 1008MHz (1:3:2:2). |
| 20:54.32 | Turl | hno: yes, it cascades through all of the if blocks on the old code |
| 20:58.21 | Turl | my code looks for the "top" and "bottom" on the small table https://github.com/allwinner-dev-team/linux-allwinner/blob/wip/allwinner-3.0/cpufreq/arch/arm/mach-sun4i/cpu-freq/cpu-freq-table.c#L89 |
| 20:58.33 | Turl | jumps through them |
| 20:58.57 | Turl | then finally applies the desired freq which should be jumpable from there |
| 20:59.27 | hno | the old code do not do what the comment says. |
| 21:00.53 | Turl | the several calls to "__set_cpufreq_hw()" should be the same on both code pieces |
| 21:01.21 | hno | <PROTECTED> |
| 21:01.49 | hno | ah, no. right. |
| 21:01.59 | Turl | no, it goes through all of the steps |
| 21:01.59 | hno | a bit tired |
| 21:02.25 | hno | yes |
| 21:05.34 | mnemoc | happy to have summoned Turl :) |
| 21:07.04 | Turl | mnemoc: :) |
| 21:10.01 | hno | hm. but what about transitions within the same group? Looks to me as if you then fiddle with the divisors as if it was crossing a boundary |
| 21:12.24 | Turl | possibly |
| 21:12.28 | Turl | but it shouldn't hurt right? |
| 21:14.50 | hno | well, i think you have an off by one error, with one intermediarey transition too many each time. |
| 21:15.22 | hno | which means you have a bad transition there. |
| 21:18.32 | hno | it does hurt as it means there is one transition crossing a boundary without gently twiddling the divisors. |
| 21:19.06 | hno | on each frequency change, even if new == old |
| 21:19.59 | hno | but need to study more carefully without kids in my arms. |
| 21:20.05 | traeak | hehe |
| 21:20.10 | traeak | you can type this well with kids around? |
| 21:21.00 | hno | I have our youngest (5 months) in my arms |
| 21:21.34 | hno | one handed typing |
| 21:22.07 | traeak | ahh |
| 21:22.24 | traeak | my 2yro usually is directly interfering |
| 21:22.44 | traeak | or stealing stuf and running off with it |
| 21:24.34 | hno | the baby isn't doing much yet, but we have 5 more.. |
| 21:25.33 | traeak | so hopefully they are just stealking stuff from each other :-p |
| 21:30.02 | hno | the 2 year old wants to type when sitting in my lab, or vander off with various items..the 3.5 year old steals stuff from everyone and trows it around. The older onse (5 year and up) leaves my stuff salone but often gets into small fights sand come running... |
| 21:30.35 | hno | all typical behaviours for kids. |
| 21:30.59 | mnemoc | :) |
| 21:31.17 | mnemoc | and no one is ever bored :p |
| 21:31.43 | traeak | hehe |
| 21:32.06 | hno | always something going. |
