| 15:10:31 | Gamera | copper, the ipod classic isn't any better than the iriver h340 |
| 15:10:44 | Gamera | my only minor grips is the very slight noise floor |
| 15:11:05 | copper | that makes the Classic better then, no noise |
| 15:11:36 | Gamera | slight hiss, I get less out of the line out, and I use an amp because it's got a really good volume knob, it's a portable soundcard, and I like the sound |
| 15:11:49 | Gamera | I got it for my phone but it sounded terrible |
| 15:12:57 | Gamera | no noise? everything has noise |
| 15:13:03 | copper | not audible |
| 15:15:42 | copper | I've measured the Classic with RMAA, got 94.9 dB of dynamic range out of it |
| 15:15:45 | Gamera | ok, what's a better one around that is anywhere near affordable |
| 15:15:51 | copper | that's nearly perfect for 16 bit audio |
| 15:15:56 | copper | Clip§ |
| 15:15:56 | Gamera | surely everything has a noise floor |
| 15:15:59 | copper | Clip+ |
| 15:16:04 | copper | similar performance |
| 15:16:17 | copper | though they're more expensive now that they're no longer produced |
| 15:16:27 | Gamera | I have an attachment to this player/recorder |
| 15:16:40 | Gamera | these are still like 200 bucks |
| 15:16:55 | copper | you can get a classic for less than that on eBay |
| 15:16:57 | Gamera | recording is a good function but barely anything is going to do that |
| 15:17:08 | Gamera | the recording function is what I like |
| 15:17:15 | copper | and a Clip+ for 100 EUR maybe |
| 15:17:33 | copper | What's your phone? |
| 15:18:18 | Gamera | s5 but for some reason it doesn't sound as good |
| 15:18:49 | Gamera | second hand, might be dodgy |
| 15:19:16 | Gamera | it's a phone, not an everything |
| 15:21:28 | Gamera | I don't have my cans, I'm pretty sure there was clipping |
| 15:21:40 | Gamera | also hd25 are 70ohm |
| 15:22:14 | johnb4 | Bilgus: I tested the removal of the "#if 0" and udelay. No crash or any other weirdness. Startup (boot) and sometimes starting of song when selected from the file browser seem (slightly) delayed. I have not noticed a major difference with or without the udelay. |
| 15:22:14 | johnb4 | I used a hires file for stress testing (192kHz, 24bit). This is 4936 kbps in FLAC and plays fine, as wav (9216 kbps) it causes buffer underruns and stutters. |
| 15:22:20 | johnb4 | The frequencies now really go low: I have uploaded a screendump of HW Info : https://www.mediafire.com/view/q9u88b16r7zc2w3/dump%20171101-145751.bmp and the registers: https://www.mediafire.com/file/yausb84x834u11u/dump%20171101-145802.bmp |
| 15:24:46 | Bilgus | which settings cause buffer underruns with the wav file? |
| 15:25:21 | johnb4 | FCLK stops for several seconds (i.e. is at 0). |
| 15:25:44 | johnb4 | Uh, I had them both turned on. |
| 15:25:55 | johnb4 | Let me try to sort it out.; |
| 15:26:17 | Bilgus | it's probably I2C but it could be the disk holding it up too |
| 15:27:28 | Bilgus | and I assume thats with the IDE underclocked as well? |
| 15:29:20 | johnb4 | that's with 'if 0' in both files removed. |
| 15:30:55 | | Join Riku [0] (~riku@hatsune.thisis.moe) |
| 15:31:17 | Riku | what are the bass cutoff settings in terms of Hz? |
| 15:31:44 | Riku | the menu shows 1, 2, 3, 4 where higher is a higher crossover frequency but what are those frequencies? I want mine set to 50Hz |
| 15:32:25 | johnb4 | with I2c disabled I still get the underruns (boost is at 100%, 248Mhz). |
| 15:34:02 | Riku | the manual says that the actual cutoff frequency used for each setting varies with sample rate so that's not much help |
| 15:34:11 | Riku | I have my iPod set to 48KHz though |
| 15:35:05 | johnb4 | i.e. disk low speed enabled. Basically all three lower bars are almost empty. |
| 15:35:47 | Bilgus | so if low disk speed is disabled its fine though? |
| 15:35:55 | johnb4 | yes. |
| 15:36:09 | johnb4 | and with i2c enabled. |
| 15:36:13 | Bilgus | I'd try adding back the #if 0 |
| 15:36:53 | johnb4 | well, in real life I won't play any song at that bitrate, so I don't mind. |
| 15:37:28 | johnb4 | I am back in 15min. |
| 15:37:57 | Bilgus | I mean we can either clock it slightly higher or just say thats the nature of the beast I mean its in the power saving menu so I think if it doesn't work for 'your' use case don't enable it |
| 15:39:05 | johnb4 | I would vote for the latter. |
| 15:40:21 | Bilgus | Ive also added display underclocking It really goes low on the v2 players like 7 kHz but I still need to test all of these things to see if they actually save power |
| 15:43:54 | Bilgus | oh one last thing could you try commenting out bitclr32(&CGU_PERI, CGU_NAF_CLOCK_ENABLE); & bitset32(&CGU_PERI, CGU_NAF_CLOCK_ENABLE); and see if it still lets you change the clock? |
| 15:44:18 | Bilgus | I wasn't sure if itd let you set the clocks while active |
| 15:45:00 | Bilgus | Riku give me a few and i'll try and see what I can find about the bass cutoff |
| 15:46:39 | Riku | hm? |
| 15:46:49 | Riku | oh you meant a few minutes my bad |
| 15:51:09 | | Quit PimpiN8 (Quit: My MacBook has gone to sleep. ZZZzzz…) |
| 15:54:55 | Bilgus | Riku what setting exactly are you wondering about? |
| 15:56:37 | Riku | bass cutoff |
| 15:56:52 | Riku | manual just says the frequency depends on sample rate and doesn't give any numbers |
| 15:57:56 | Bilgus | Band 0: Low shelf filter? |
| 16:00 |
| 16:00:01 | Bilgus | ok better yet which Ipod and can you paste the manual entry for the setting? |
| 16:00:05 | johnb4 | Bilgus: all 4 occurances of "bitclr32(&CGU_PERI, CGU_NAF_CLOCK_ENABLE);" ? |
| 16:00:27 | Bilgus | 2 are bitclr and 2 are bitset but yes |
| 16:01:22 | johnb4 | ;-) got it. Where do I check? In HW Info? which item? |
| 16:01:39 | Bilgus | the IDE frequency should still change |
| 16:02:37 | Bilgus | I think it'll probably allow setting it on the fly the others seem to |
| 16:03:51 | Bilgus | Also I have the latest patch up on gerrit that allows slowing down DBOP and SSP, SSP shouldn't have any effect on the v1 devices but dbop should make the screen slower where as v2 devices the reverse |
| 16:05:17 | johnb4 | I soon will lose track of my local versions / changes :-) |
| 16:05:56 | Bilgus | thats what branches are for |
| 16:06:28 | Bilgus | where ever you are now just type checkout -b ,NEW branch> and do your thing |
| 16:06:39 | Bilgus | <New branch> |
| 16:07:55 | Bilgus | once I figure out what actually works I'll clean this all up and make it more generic |
| 16:10:12 | Bilgus | Riku after looking through the manuals you must have an Ipod video its probably implemented by the device since the others don't seem to have it |
| 16:11:14 | Riku | https://download.rockbox.org/manual/rockbox-ipodvideo/rockbox-buildch6.html#x8-1070006.4 |
| 16:11:20 | Riku | also I have an iPod Classic |
| 16:16:07 | Bilgus | yeah there are no indications of what the frequency might be its literally a setting for the hardware itself |
| 16:17:32 | Bilgus | you might be able to look up the hardware and find what it implements it as or wait for one of the IPOD devs to answer, its probably easier to test it with an oscilloscope |
| 16:17:38 | johnb4 | Shouldn't the rbversion string change if I comment those lines (even if not commited) or is it only based on commits (plus the M at the end for modifications)? |
| 16:18:31 | Bilgus | Idk john I can do small changes and the version string stays the same |
| 16:19:00 | Bilgus | not sure how exactly it is calculated |
| 16:19:05 | johnb4 | so it seems to be based on commits. |
| 16:21:25 | johnb4 | Bilgus : IDE still goes down to 15MHz |
| 16:21:56 | Bilgus | so can you disable it and enable it and see the freq change then? |
| 16:22:25 | johnb4 | you mean disk low speed? |
| 16:23:16 | Bilgus | yes |
| 16:24:00 | johnb4 | If disabled it says 49Mhz actual (instead of 50MHz set). |
| 16:36:40 | Bilgus | but it does change back and forth? |
| 16:37:02 | johnb4 | If I enable/disable: yes |
| 16:37:15 | Bilgus | did it say 50 MHZ actual before? |
| 16:37:33 | Bilgus | that sounds like a rounding error |
| 16:37:34 | johnb4 | I think so. |

| 16:57:09 | Bilgus | Ok I just pushed one last thing that adds the SSP_CPSR to the debug menu and cleaned up the CGU_IDE code a bit this should be about all till I figure out the results of each setting |

| 20:04:12 | johnb5 | Bilgus: What gerrit tasks and in which order are now required for g#1709 ? |
| 20:04:15 | fs-bluebot | Gerrit review #1709 at http://gerrit.rockbox.org/r/1709 : As3525 v1/v2 Add power savings menu by William Wilgus |
| 20:04:52 | johnb5 | I failed 2h ago and now again with the latest update ... |
| 20:05:10 | Bilgus | I think still the same ones but hold on a second I cleaned everything up now |
| 20:06:00 | Bilgus | let me check that it still compiles and I'll commit the last of my changes |
| 20:07:12 | Bilgus | it'll be update to master g1712 g1714 and then g1709 still |
| 20:17:45 | Bilgus | Is there an option to de-select plugins from the build? |
| 20:17:56 | Bilgus | If not we need one these things take forever |
| 20:18:37 | johnb5 | I disable the plugins by changing the line in tools/configure. |
| 20:19:01 | johnb5 | that's all of them |
| 20:26:34 | Bilgus | ok I committed the latest it built clean for the clip+ and fuzev1 |
| 20:27:18 | Bilgus | Unless theres some error or something needs changed for making manual entries this should pretty much be it |
| 20:28:24 | Bilgus | I still need to do runtime tests to see what actually makes a difference but a few things have changed, the cpu undervolt setting is now cpu low voltage and I merged sbop and ssp into display low speed |

| 20:51:59 | cela | Newest build I have for Zen X-Fi 2 that works ok is 193c5df from 2014! Do we have any builds in between I can try to bisect? |

| 20:58:06 | cela | Seems to be a file access problem as I cannot select fonts in rockbox either, if someone can point to some old builds I'll try to bisect the issue. thanks. |

| 20:59:14 | johnb6 | Bilgus: the Display Low Speed doesn't work on the Fuze: selecting Yes takes a long time and then the display gets smeared. |
| 20:59:32 | | Quit cela (Quit: Page closed) |
| 20:59:39 | | Quit johnb5 (Ping timeout: 240 seconds) |
| 20:59:40 | johnb6 | with all other disabled. |
| 20:59:50 | Bilgus | that means its probably not letting it set it was it working before with dbop? |
| 21:00 |
| 21:00:29 | johnb6 | this was the 1st time I compiled with this feature. |
| 21:01:22 | Bilgus | ah ok |
| 21:04:48 | Bilgus | it might just be too low for it in clock-target.h try changing #define AS3525_DBOP_DIV_SLOW 0x7 to 0x2 and see if it changes anything |
| 21:05:56 | Bilgus | if not I probably need to disable the clock while I set it |
| 21:17:16 | johnb6 | It's different: it stays alive, there are changing dots on the display ( like stars in the sky) and the display has a huge delay updating when I move through the menus. |
| 21:18:05 | johnb6 | and now after the screen turned off, it's totally smeared again. |
| 21:18:29 | johnb6 | kinda completely white |
| 21:18:53 | Bilgus | hmm let me read the data sheet some more but I think its probably not going to let it be lower does it work with 0x1? |
| 21:21:35 | Bilgus | that would be half the speed |
| 21:22:10 | Bilgus | and if that still doesn't work try it with 0x0 just to be sure its not messing up writing the register |
| 21:26:40 | | Quit alexweis_ (Remote host closed the connection) |
| 21:28:40 | johnb6 | with 0x1 it is always recovering, but in between has tremendous artefacts |
| 21:30:25 | johnb6 | and lagging |
| 21:31:27 | Bilgus | yeah so it pretty much can't deal with any slower clock |
| 21:32:11 | Bilgus | I'll remove the display low speed option from v1 devices |
| 21:32:20 | | Nick johnb6 is now known as johnb2 (~johnb2@HSI-KBW-134-3-236-217.hsi14.kabel-badenwuerttemberg.de) |
| 21:33:01 | Bilgus | Thanks for testing :) |
| 21:33:08 | johnb2 | No problem. |
| 21:39:23 | Bilgus | ah. Time constraining for the module should be done with 65 MHz, if there is a demand the time constraints for the output pads can be reduced. |
| 21:39:42 | Bilgus | now to figure out how to do that |
| 21:43:14 | johnb2 | BTW, as for the MBOOT BL, will this now automatically picked up by Rockbox Utility or has this to be set on the server side explicitly? |
| 21:43:38 | johnb2 | when patching the OF ... |
| 21:44:17 | johnb2 | *be picked up |
| 21:44:55 | Bilgus | I think the new bootloaders still need built and put there |
| 21:45:32 | Bilgus | Yeah the timing on the output pads changes across each device I think i'm going to leave well enough alone |
| 21:46:25 | | Quit xorly (Ping timeout: 240 seconds) |
| 21:46:39 | Bilgus | john is the SSP_CPSR in your debug menu all zero? |
| 21:48:30 | johnb2 | going to HW Info gave me a divide by 0 :-) |
| 21:49:50 | johnb2 | even when disabling all power saving options |
| 21:50:27 | johnb2 | Previously like patch 09, it was different to 0. |
| 21:51:06 | johnb2 | never mind, I was talking about a different parameter. So I don't kn ow. |
| 21:51:35 | johnb2 | I never looked at SSP_CPSR. |
| 21:52:19 | Bilgus | thats probably ssp doing that |
| 21:52:39 | Bilgus | give me a second i'll commit the fixes |

| 21:59:58 | | Quit amayer (Quit: Leaving) |
| 22:00 |
| 22:03:00 | johnb2 | Bilgus : yes, SSP_CPSR stays at 0 |
| 22:03:24 | Bilgus | yeah I kinda figured when you said it gave you a divide by zero |
| 22:03:56 | Bilgus | I went ahead and left the register in the debug menu but defined out the actula clock |
| 22:05:21 | Bilgus | those v1 devices don't leave much for the power save menu hopefully i2c/disk along with power save gives a pretty substantial improvement |
| 22:06:19 | johnb2 | I will run battery bench on the weekend when I am back home. |
| 22:06:55 | johnb2 | But I feel we get close to the 18h of the FS patch. |
| 22:07:12 | Bilgus | about the only other thing would be to lower the max clock on the cpu which isn't out of the question |
| 22:08:00 | johnb2 | No voltage scaling was involved so far, was it? |
| 22:08:04 | Bilgus | nope |
| 22:08:31 | Bilgus | but the v1 devices don't have voltage scaling as of yet |
| 22:08:58 | Bilgus | I don't know if that means its not capable or if it just isn't implemented |
| 22:11:27 | Bilgus | yeah the flyspray patch wasn't switching voltage either |
| 22:12:30 | | Part ntd |
| 22:19:30 | Bilgus | ah while it wasn't voltage switching it did drop the voltage though |
| 22:20:17 | Bilgus | I wonder if it just takes too long for the voltage to settle or if it just wasn't added to the clipv1 and fuze v1 devices |

| 22:22:03 | | Quit dys (Ping timeout: 240 seconds) |
| 22:22:08 | johnb2 | sure |
| 22:23:18 | Bilgus | its odd the code is there for it and its a as3525v1 so I'm not sure why they don't have it |
| 22:24:00 | Bilgus | unless it makes it unstable and in that case we could probably get away with setting it highish and drop it a bit in the powersave menu |

| 22:31:07 | Bilgus | hmm there must be something else that depends on that flag brb |
| 22:32:51 | Bilgus | thats kinda stupid /* If SD card present Boost cpu for voltage */ |
| 22:33:12 | Bilgus | let me look and see what card_detect_target is actually doing |
| 22:36:02 | Bilgus | move static inline bool card_detect_target(void){.....} to just before static void enable_controller(bool on){... |
| 22:36:37 | Bilgus | wtf must have just gotten missed since HAVE_ADJUSTABLE_CPU_VOLTAGE wasn't defined |
| 22:41:01 | johnb2 | it's compiling now. Should I disable the other power saving setting for testing? |
| 22:41:36 | Bilgus | might try both and see if anything gets funky |
| 22:41:58 | Bilgus | in the data sheet it says you only need 1.2v for the max cpu speed |
| 22:42:04 | | Quit alexweis_ (Remote host closed the connection) |
| 22:42:15 | Bilgus | and can drop it to 1.10v for lower speeds |
| 22:46:14 | | Quit lebellium (Quit: ChatZilla 0.9.93 [Firefox 56.0.2/20171024165158]) |
| 22:46:24 | johnb2 | Is this now enabled with the flag? |
| 22:48:12 | Bilgus | yeah though I took out the option in the power save menu so its gonna be 1.10v at unboosted cpu |
| 22:49:00 | Bilgus | if it acts funny we can try adding back the option and that will make it 1.15v unboosted with cpu low voltage == disabled |
| 22:51:41 | johnb2 | yeah, now Cpu Frequency shows also voltage in the debug menu like for V2 devices. And it's at 1.1V unboosted as you said. |
| 22:52:41 | Bilgus | nice You might test it out a bit and see if it works properly Now I bet we are at 18hrs |
| 22:53:27 | johnb2 | How would I stress test? Eqs, high bitrate Opus, ...? |
| 22:53:31 | | Join PimpiN8 [0] (~textual@145.132.155.235) |
| 22:54:21 | Bilgus | it affects quite a bit probably those plus some heavy codecs |
| 22:55:12 | Bilgus | AAC-HE if it even played them before |
| 22:55:50 | Bilgus | but I think most of that would probably boost the cpu anyways so IDK |
| 22:55:54 | johnb2 | Any sample files around? |
| 22:56:11 | Bilgus | yeah up on the site brb |
| 22:56:21 | johnb2 | ok, then I will use my opus ones. |
