00:37:03 | preglow | i haven't heard much about it |
00:37:06 | preglow | what is/was it? |
00:37:07 | Bagder | we'll talk about it around the camp fires |
00:37:19 | amiconn | rasher: It's been there for years now. See http://www.rockbox.org/bugs.shtml the very first entry... |
00:37:21 | HCl | "back when i was young, we used to have the rld bug!" |
00:37:22 | rasher | preglow: subscribe to the damn mailinglist already |
00:37:30 | preglow | i've been on it for ages |
00:37:46 | rasher | oh ah |
00:37:50 | preglow | i don't read archos related posts |
00:37:54 | amiconn | However, the reason for the bug changed |
00:38:17 | rasher | I find myself reading most of the posts |
00:38:31 | amiconn | First, it was that the hitachi disk simply won't answer if they time out. They need a (soft) reset, which Linus added.... |
00:39:08 | amiconn | ...but accidentally used a mutexed function for that, calling it from within a mutexed function... |
00:39:15 | preglow | hah |
00:39:52 | rasher | hilarity ensued |
00:40:07 | amiconn | Fix committed. |
00:40:32 | rasher | this mandates a digest entry |
00:41:43 | Bagder | possibly await testing results from some of the frequent victims of this bug |
00:41:52 | amiconn | Yeps |
00:42:09 | amiconn | I know a quite reliable way, just it will take a while |
00:42:42 | amiconn | I need to run my player in the car, and run out of batteries while driving. This _always_ ended in an rld before... |
00:43:50 | rasher | talk to me about running out of batteries taking a while |
00:43:57 | amiconn | I knew there was a reason why I kept the 10 GB hitachi hd in the player and didn't swap it for the 20 GB IBM... |
00:44:02 | rasher | those iriver battery tests were the height of boredom |
00:44:48 | preglow | now let me tell you of a little thing called imdct |
00:45:06 | amiconn | Did you find something about the slowdown? |
00:45:16 | preglow | no |
00:45:46 | rasher | that is a horrible tale of misfortune :< |
00:45:49 | preglow | i could try to work on it some more now, but i'm a couple of notches too tired |
00:47:10 | preglow | i suspected the code was misaligned, but no |
00:47:49 | preglow | linus said he'd shove it through the bdm one day, perhaps that'll clear some things |

00:59:13 | HCl | what recording problem? |
00:59:16 | preglow | the rigours of development |
00:59:23 | HCl | yup |
00:59:36 | MoosCamaro | It's a pity amiconn don't work in iriver :( |

01:00:55 | * | HCl does an cvs update and finds something that he thought he committed days ago o.o; |
01:00:58 | * | HCl commits. |
01:01:42 | amiconn | HCl: There is a problem with recording on archos. With high quality settings and high sample rate, the recording 'breaks down' at some time within the recording, producing only corrupt frames after that point |
01:01:50 | HCl | odd.. |
01:02:01 | preglow | and it's not a mas problem? |
01:02:07 | amiconn | It might be either a problem of our transfer routines, or a MAS problem |
01:02:26 | preglow | let me tell you how eternally gratefull i am that i will never write a codec for that chip |
01:02:27 | HCl | mhm... |
01:02:32 | HCl | :) |
01:02:36 | amiconn | I have a suspicion, but to verify if, I need to do test recordings with all possible combinations... |
01:02:51 | HCl | whats your suspicion? |
01:02:51 | amiconn | preglow: This is harvard.... |
01:03:05 | rasher | amiconn: better write up a matrix sooner rather than later :( |
01:03:08 | amiconn | ....and the test recordings need to be longer ones |
01:03:13 | preglow | amiconn: all dsps are harvard |
01:03:16 | preglow | amiconn: all i know of, at least |
01:03:54 | amiconn | preglow: There are some docs... from looking at them, writing code is really an ugly piece of **** |
01:04:13 | preglow | amiconn: yes, my statement is based on having read those docs |
01:04:22 | amiconn | It's harvard, has only little ram, and you need to synchronise the ops manually... |
01:05:35 | amiconn | HCl: My suspicion is that the MAS cannot handle m/s stereo properly at higher quality settings |
01:06:12 | amiconn | Archos firmware recording doesn't have this problem, and it uses simple stereo, not m/s.... |
01:06:30 | preglow | well, why don't you try feeding it difficult frames? |
01:06:47 | amiconn | Talking encoding here... |
01:06:59 | amiconn | But then archos firmware does have another problem with long recordings... it sometimes simply freezes |
01:07:07 | | Join |it|ChasKi` [0] (~faggotypa@82-69-23-235.dsl.in-addr.zen.co.uk) |
01:07:09 | preglow | yes, i know we're talking encoding |
01:07:11 | | Nick tvelocity is now known as tvelocity[away] (~tony@ipa157.7.tellas.gr) |
01:07:27 | amiconn | So how do you mean, feed it difficult frames? |
01:07:37 | amiconn | Feeding white noise, or what? |
01:07:40 | preglow | data that's hard to encode |
01:07:51 | preglow | depends on what you mean by 'higher quality settings' |
01:08:03 | preglow | white noise isn't necessarily that hard to encode |
01:08:43 | amiconn | The MAS has only a rough method to set the desired average bitrate, a quality value, ranging 0..7 |
01:09:23 | amiconn | My idea is to test all possible combos of quality setting, sample frequency, mono/stereo |
01:09:44 | amiconn | All this with and without m/s stereo enabled |
01:10:18 | amiconn | ...doing at least 5 recordings of 2 h each, the check the mp3 files with mp3utility or similar |
01:10:33 | amiconn | I can probably cut short at some points |
01:10:34 | HCl | sounds like a hell of a task, heh |
01:10:35 | HCl | :x |
01:11:10 | amiconn | Like, when going down with the quality value, and q=3 doesn't produce any errors, I can skip doing 2..0 |
01:11:40 | preglow | why don't you use ordinary stereo at higher quality settings anyway? i believe that's the usual practice |
01:11:41 | rasher | binary bugtesting |
01:12:11 | amiconn | preglow: Even the highest quality setting isn't really high quality mp3 wise |
01:12:19 | preglow | doesn't surprise me |
01:12:28 | preglow | decent encoding is very resource intensive |
01:12:37 | amiconn | The mas won't produce any frame with bitrate >192 kbps, and the average is ~175 kbps |
01:12:53 | preglow | it probably doesn't have enough ram for such frames, heh |
01:13:06 | amiconn | It does for decoding... |
01:13:34 | preglow | encoding is quite a bit worse than decoding |
01:13:41 | amiconn | It even handles the highest mp2 bitrate properly, which is 384 kbps |
01:14:01 | preglow | yeah, the frames themselves aren't very large |
01:14:03 | amiconn | preglow: Yes, but the ram is the same |
01:14:20 | amiconn | The codec itself doesn't reside in ram, but in rom |
01:16:23 | amiconn | My guess for the frame size limit on encoding would be the limited processing power |
01:16:48 | preglow | hmm |
01:16:49 | preglow | might be |
01:17:47 | amiconn | The mas is running at 18.4 MHz |
01:18:03 | preglow | it's a frigging miracle it gets anything done at all |
01:18:06 | amiconn | Try to beat that with libmad ;) |
01:18:28 | preglow | ahaha |
01:18:57 | preglow | if i double the efficiency it'll be realtime at 30mhz or something |

10:46:32 | HCl | afk |
10:47:24 | Bagder | HCl: people will upgrade when MS drops support of their older win versions, I'm sure |
10:49:31 | ashridah | what are you talking about? people still use NT4 and win95, and neither of those have had support for years |
10:49:50 | Bagder | some do, yes |
10:49:55 | Bagder | but many follow |
10:50:01 | LinusN | ashridah: of course, but the vast majority will upgrade |
10:50:39 | LinusN | do not underestimate the power of the dark side |
10:50:46 | ashridah | i'm not sure it's as true. it becomes more true over time, as older pcs are discarded |
10:50:55 | ashridah | but not because ms stops support |
10:51:09 | LinusN | ashridah: true |
10:51:16 | Bagder | I'd say it is both |
10:51:34 | LinusN | the corporations need the support |
10:51:36 | Bagder | and that all new PCs will have the new MS os installed |
10:51:40 | LinusN | home users don't care |
10:51:48 | ashridah | i know people who STILL keep installing nt4 on stuff because it's what they know. and lots of existing sites don't rip out stuff that works unless they can possibly help it |
10:52:38 | Bagder | there are people using C64s too |
10:52:51 | Bagder | the vast majority don't however |
10:53:18 | Bagder | I'm just saying tcpa or not makes very little difference |
10:54:04 | ashridah | tcpa might actually be useful, just not the way ms wants it to be. |
10:54:12 | Lynx_ | just wait until dell and co stop delivering drivers for old windows versions. ist really hard getting a new dell laptop to run win2000 already. |
10:54:23 | Lynx_ | s/ist/it's/ |
10:54:44 | ashridah | Lynx_: yes, which is why i said discarding old pcs tends to be the driving force behind upgrades. |
10:55:34 | ashridah | on the desktop side of things, that usually happens before the service period ends, but certainly not in the server world. |
10:56:29 | Lynx_ | hmm, i'm not sure the server world will have too much an impact on the success of longhorn? |
10:57:54 | LinusN | call me a cynic, but longhorn isn't about success or not, the consumers don't have a choice |
10:58:44 | LinusN | their choice is to run another os |
10:58:52 | ashridah | nope. there'll be a crossover period where one can get XP or longhorn on a new laptop, but that'll shift pretty quick. |
10:59:08 | LinusN | if they want windows, longhorn it will be |
10:59:17 | LinusN | sooner or later |
10:59:19 | amiconn | LinusN? |
10:59:27 | ashridah | but it'll take the expiry of existing hardware (either at the end of a service contract with a pc supplier, or age in general) to force the mass move to longhorn |
10:59:36 | t0mas | hm... |
10:59:41 | LinusN | amiconn: yes? |
10:59:50 | t0mas | I guess... with some right marketing linux can make use of tcpa |
11:00 |
11:00:20 | ashridah | the big problem is that tcpa keeps getting associated with DRM |
11:00:21 | t0mas | just some commercials telling people what tcpa can do... and how it works... and that linux doesn't have it... |
11:01:02 | ashridah | t0mas: there's nothing intrinsically wrong with tcpa as a general idea, the problem is with whom the ultimate control lies. |
11:01:25 | t0mas | yes, and that should be explained to some people |

11:14:57 | LinusN | it's easy to come up with doomsday arguments against tcpa |
11:15:19 | LinusN | nobody knows how true they will be |
11:16:02 | LinusN | the problem is that tcpa certainly seems to pave the way |
11:16:21 | HCl | ashridah: woah, let me get one thing straight, tcpa *does not* protect your computer. |
11:16:29 | HCl | it only limits the software you're allowed to run |
11:16:47 | HCl | in order to make people pay for software more |
11:16:51 | HCl | rather than copying it |
11:17:26 | HCl | also, linux will be possible, but it will effectively kill oss since you'd have to buy an entirely new certificate if you'd even make a tiny change to the kernel |
11:17:38 | HCl | not to mention the entire kernel has to be screened before it'll be accepted |
11:17:47 | ashridah | HCl: not if you're the one doing the signing. |
11:17:56 | HCl | um. |
11:18:05 | HCl | i highly doubt that any end user will be able to sign, lol. |
11:18:13 | HCl | that would completely destroy the entire purpose of tcpa ;p |
11:19:26 | ashridah | that depends on which way you use it. |
11:19:40 | HCl | that depends on which way microsoft uses it, heh |
11:19:43 | ashridah | you can use it to protect software you distribute to other people, thus, windows can use it to enforce drm. |
11:20:07 | ashridah | but if you implemented in your own linux kernel, signed your own software, and then took that stuff off the net, it becomes a far more advanced tripwire |
11:20:21 | HCl | as far as i know, it will not allow people to "sign" software. |
11:20:22 | ashridah | since the pc literally refuses to run signed stuff, and you've signed your own gear. |
11:20:51 | ashridah | now, if pc manufacturers are the ones holding the signing process, that clearly fucks things up. |
11:21:01 | HCl | yes, thats the entire idea, they will :p |
11:21:19 | t0mas | ofcourse they will... |
11:21:22 | Rick | imagine a h120 with tcpa in it, ebil >:o |
11:21:28 | HCl | users will just have access to signing documents and stuff like that |
11:21:33 | Rick | no rockbox ;( |
11:21:37 | HCl | but nothing that can potentially breach security, like software |
11:21:41 | t0mas | HCl: no, that will be done automaticly ;) |
11:21:50 | t0mas | word signes all doc −−> openoffice can't read them |
11:21:58 | t0mas | noobs don't care... |

11:24:12 | ashridah | HCl: the documents i've read seem to suggest one can ask the tcpa chip to generate a machine specific private key. |
11:24:26 | ashridah | (and that it doesn't take control of the boot process) |
11:25:46 | preglow | damn, sounds like the cpu fan is trying to gnaw its way out if its own casing |

11:28:09 | rob- | As far as I understand, tcpa will be able to be disabled by the user, in which case it will act exactly like a pc without it. Of cource any software that relies on it for drm won't work. |
11:28:44 | preglow | ahh, that's a fine initiative |
11:29:04 | ashridah | rob-: which won't matter one iota to someone running linux in the first place |
11:29:12 | rob- | exactly |
11:30:33 | ashridah | the only people who have anything to fear from DRM are people who use proprietary software. same goes for TCPA. |
11:30:52 | ashridah | and to a lesser extent, since TCPA can simply be disabled. |
11:30:53 | rob- | and it can actually help the security of linux by allowing you to verify the authenticity of all programs running. |
11:31:06 | * | ashridah nods. |
11:31:10 | ashridah | can't modify it without resigning it |
11:31:24 | ashridah | thus it becomes all good until someone invents a constant-time factorisation algorithm :) |
11:31:33 | rob- | great for servers:-) |
11:31:53 | * | ashridah could seriously see tcpa as a souped up tripwire in the right setting |
11:32:10 | ashridah | irritating for a developer's platform tho |
11:32:11 | LinusN | tcpa will probably be used to sign documents etc |
11:32:38 | LinusN | meaning you won't be able to read some documents without the tcpa hardware |
11:32:59 | | Quit amiconn (Read error: 60 (Operation timed out)) |
11:32:59 | | Nick amiconn_ is now known as amiconn (~jens@pD9E7F838.dip.t-dialin.net) |
11:33:13 | LinusN | even worse, not being able to read Office docs at all with any other applications |
11:33:17 | rob- | just like encrypted pdfs today. |
11:33:25 | ashridah | LinusN: yeah, but if the signature is done in tcpa, wouldn't that imply that any software can unencrypt the data, provided it has the keys? and wouldn't the key need to be distributed to the people whom are supposed to be reading it? |
11:33:43 | ashridah | or do you encrypt it with THEIR key to start with, again, what's the problem, if it's tcpa's job to decode it? |
11:34:18 | ashridah | it looks more like 'i'm me, i'm the recipient, give me the raw data' wihch you then feed to openoffice. |
11:35:07 | HCl | i think it'll mostly annihilate copying software (illegally) |
11:35:11 | ashridah | at least, from the looks of the tcpa pdf you mentioned before (which looks more plausible than most other doomsday scenarios, (like windows media player actually NEEDS tcpa to drm at all) |
11:35:24 | * | LinusN goes to lunch |
11:35:32 | HCl | http://www.againsttcpa.com/tcpa-faq-en.html |
11:35:38 | ashridah | HCl: that's not necessarily a bad thing. it could be really really frustrating, particularly if a vendor dies |
11:35:49 | HCl | hm? |
11:36:22 | ashridah | if a company dies however, legally, they're obligated to give you everything you need to maintain the support implied in anything you signed. (of course, for shrink wrap software, that support isn't much) |
11:36:52 | amiconn | LinusN: I mean, any comments on the recording loop, planned recording tests and/or the rld report? |
11:37:06 | rob- | That will be an advantage for opensource, until the vendors realize that drm hurts their business |
11:41:02 | ashridah | the part that annoys me the most is that any stupid law like CBDTPA that'd really fuck over non-drm'ed machines would automatically get accepted by our country, just because america likes shooting itself in the foot. |
11:42:40 | HCl | heh.. |
11:42:46 | HCl | aren't they already? with their dmca.. |
11:43:25 | ashridah | not to the same extent |
11:43:34 | HCl | heh, yea, tcpa is worse. |
11:43:43 | ashridah | the only companies that a law like CBDTPA would help would be hardware manufacturers and microsoft. |
11:43:50 | rob- | that's what happens when the law makers are controlled by corperations |
11:43:54 | ashridah | (in the short to medium term) |
11:46:21 | preglow | wouldn't be the first time a law happends to cater to big companies, no |
11:47:17 | ashridah | yeah. those guns those nuts claim are to protect them from the government or the kind of england (long live the king) clearly need some dusting off :) |
11:48:51 | ashridah | hm. perhaps in order to protest it, we should suggest to the protestors that they dress the law up like the king of england (long live the king) |
11:49:01 | ashridah | nevermind that the king is actually a queen atm, but yeah: ) |

12:53:28 | amiconn | Then I don't record often |
12:53:41 | LinusN | let's commit it |
12:54:38 | preglow | do you have any idea why the bootloader destroys vorbis playback? |
12:54:54 | LinusN | no |
12:55:02 | preglow | sounds incredibly unlikely that modifying your firmware would have such a subtle effect |
12:55:38 | LinusN | but i guess they assume that the onboard peripherals are uninitialized, and the boot loader changes that |
12:55:59 | preglow | probably, but vorbis playback, of all things? |
12:56:07 | LinusN | weird indeed |
12:57:12 | LinusN | hmmm, i have an idea for a test |
12:58:28 | LinusN | anyone here up for a test with the 1.65 firmware? |
12:59:22 | preglow | don't know how keen i am to possibly destroy my vorbis playback, since most of my files are vorbis... |
12:59:40 | dwihno | I see Jens' did some kind of ATA thing... Supposedly it helps RLD. Any confirmations on this one? |
13:00 |
13:00:06 | preglow | well, he thinks he's got it fixed |
13:00:33 | dwihno | *checks out* |
13:01:00 | LinusN | dwihno: it is definitely good rld medicine |
13:02:13 | dwihno | RLD medicine for all \o/ |
13:02:29 | dwihno | I thought the Hitachi disks were to blame |
13:03:02 | LinusN | they are |

13:03:58 | HCl | hellow |
13:04:16 | LinusN | preglow: any ideas about the imdct_l issue? |
13:04:18 | dwihno | My disk has started to "click" occasionally (it reads/writes lot of data, clicks and then resumes without any error) |
13:04:35 | dwihno | Supposedly I should check the backup's ok |
13:05:20 | preglow | LinusN: none, and no time, i have to code other things these days |
13:05:49 | LinusN | how often is imdct_l called? |
13:05:52 | preglow | it's not cache issue, and it's not misalinged, that's more or less what i know |
13:05:54 | preglow | very often |
13:05:57 | preglow | once for every subband |
13:06:03 | preglow | which there are 32 of, i think |
13:06:19 | preglow | times two for stereo |
13:06:39 | LinusN | ok, and you tried to exit before the loop, and it was still slower than the original? |
13:06:40 | preglow | and a frame isn't very long, so it's called pretty often |
13:06:43 | preglow | yep |
13:06:53 | LinusN | fishy indeed |
13:07:04 | * | preglow concurs |
13:08:40 | preglow | it's very memory intensive in places |
13:08:47 | preglow | that might be it, but i doubt it, since all data is in iram |
13:09:40 | preglow | other places again don't touch memory at all |
13:10:35 | preglow | when i put the loop in iram, performance went up to old imdct_l standards |
13:10:51 | preglow | but i was thinking more in the lines of better performance than old imdct_l ;) |
13:16:56 | amiconn | LinusN: Do you have a clue what might cause the garbled data in case where there would have been an rld before? |
13:17:11 | amiconn | Shouldn't ata_read_sectors() return an error? |
13:17:48 | HCl | garbled data? |
13:20:21 | LinusN | amiconn: it probably returns an error, but i guess it isn't handled correctly in all places |
13:20:42 | LinusN | i suspect the sector cache in read() |
13:25:42 | LinusN | preglow: isn't the old imdct_l implementation inlined? |
13:28:23 | amiconn | LinusN: Iiuc, there should be room for improvement of the retry. |
13:28:47 | LinusN | amiconn: probably |
13:29:06 | amiconn | Afaics, the retry currently retries the whole transfer, ignoring any sectors that might already be transferred correctly |
13:29:29 | LinusN | yes |
13:30:12 | preglow | LinusN: yeah |
13:30:27 | * | LinusN has a theory |
13:30:40 | preglow | i'd sincerely like to hear it if it involves inlining :P |
13:31:05 | LinusN | the cache is one-way only |
13:31:42 | preglow | meaning? |
13:31:57 | LinusN | the imdct_l function may be located such that it occupies the same cache lines as the III_decode loop |
13:32:18 | LinusN | so it has to refill the cache for every call to imdct_l |
13:32:26 | LinusN | and when it returns |
13:32:52 | LinusN | that wouldn't be a problem with a two-way cache |
13:33:04 | LinusN | but hey, this is coldfire... |
13:33:56 | preglow | occupies the same cache lines? what? i thought physical addresses were pretty irrelevant for caches |
13:34:21 | LinusN | on the contrary |
13:34:29 | amiconn | The coldfire cache is direct-mapped, not associative |
13:34:34 | LinusN | it's a set-associative cache |
13:34:36 | preglow | bahhh! |
13:34:40 | LinusN | afaics |
13:34:50 | preglow | well |
13:34:54 | amiconn | LinusN: It's set-associative? Maybe I overlooked sth |
13:35:03 | preglow | no wonder i get huge friggin boosts from stuffing the loop in sram, then |
13:35:18 | preglow | wait, that i still don't understand :V |
13:35:18 | rasher | Do I sense a breakthrough? |
13:36:20 | preglow | not really |
13:36:35 | preglow | there's not much i think i can do to remedy this anyway |
13:36:44 | LinusN | oh yes |
13:37:23 | amiconn | MCF5249 manual: 5.1 INSTRUCTION CACHE FEATURES: 8KByte Direct-Mapped Cache |
13:37:34 | LinusN | direct mapped |
13:37:55 | preglow | apart from stuffing everything in iram or somehow remapping function locations |
13:39:17 | LinusN | amiconn: a direct mapped cache is the same thing as a 1-way set-associative cache |
13:39:41 | LinusN | which is pretty lame |
13:40:16 | LinusN | preglow: yes, we can make sure that the imdct_l function is right next to the III_decode function in memory |
13:40:17 | amiconn | nitpicking? ;) |
13:40:24 | LinusN | amiconn: :-) |
13:41:36 | LinusN | not only does the coldfire have an instruction-only cache, it has a *lame* instruction-only cache :-) |
13:41:47 | preglow | no surprises |
13:41:59 | Bagder | it goes fine with the rest of it ;-) |
13:42:10 | preglow | argh |
13:42:14 | LinusN | consistency is a good thing, isn't it? :-) |
13:42:21 | preglow | my new screen is due in a couple of hours, but i want it now! |
13:42:29 | LinusN | preglow: i know the feeling |
13:42:37 | preglow | this flickering piece of shit is mocking me |
13:43:09 | LinusN | i remember having to wait three days for the wiggler to clear customs in sweden |
13:43:15 | preglow | hahaha |
13:43:25 | preglow | god, how i love customs |
13:43:25 | LinusN | it took one day to ship it to sweden |
13:43:41 | rasher | But you're in euroland |
13:43:41 | preglow | they usually spend about three days in just looking at stuff before they actually process it here |
13:43:53 | rasher | so no customs :) |
13:44:10 | LinusN | rasher: hehe, except when it comes from usa |
13:44:49 | rasher | True |
13:45:02 | rasher | Trying to avoid that, myself |
13:45:35 | amiconn | Hmm, I hope I won't get those problems... |
13:45:38 | preglow | my god, direct mapped caches suck |
13:45:51 | LinusN | preglow: they sure do |
13:45:53 | preglow | amiconn: bought a h140? :P |

13:47:58 | preglow | you aren't hardcore when you endorse mp3 players in your free time, no matter how mean you look |
13:48:00 | rasher | Flashblock is pretty good |
13:48:10 | rasher | it doesn't do that, but it's fairly nice |
13:48:48 | rasher | Why oh why did they chose to advertise it with a girl who's roughly 50% larger than the DAP |
13:48:48 | preglow | LinusN: are fully associative caches common? |
13:48:57 | rasher | aren't you supposed to make it look SMALL |
13:50:16 | preglow | 2 way set-associative looks like a nice trade-off |
13:50:48 | amiconn | rasher: I don't see anything on that page.. apart from the top banner and a black window... |
13:51:16 | amiconn | ...ah, and a faint "roc" background to the left & right |

13:52:40 | amiconn | Meh, web "designers" :/ |
13:52:50 | Lynx_ | rasher: yes, i love flashblock |
13:52:51 | LinusN | preglow: fully-associative caches are extremely uncommon |
13:53:47 | LinusN | they use up huge amounts of die space, and can actually make the system slower |
13:54:03 | LinusN | since the cache search can take time |
13:54:09 | preglow | true |
13:54:13 | LinusN | to find out if it is a hit or not |
13:54:37 | LinusN | 2-way set would be nice |
13:54:50 | preglow | LinusN: but anyway, finding out it your suspicion is correct would just entail having a look at where stuff is mapped after loading mpa2wav, yes? |
13:55:00 | LinusN | yes |
13:55:07 | preglow | and all plugins are mapped to the same address? |
13:55:11 | LinusN | yes |

14:08:44 | LinusN | yup |
14:09:35 | amiconn | preglow: Should be easy to find out from the .map file |
14:09:44 | kurzhaarrocker | Do mp3 files have ape tags? |
14:09:49 | amiconn | (temporarily making the functions non-static as needed |
14:09:53 | LinusN | from the .map file, i see that they collide |
14:10:07 | LinusN | kurzhaarrocker: yes, if you have run mp3gain on them |
14:11:52 | preglow | LinusN: so, how to shuffle stuff around? just move the function definitions around? :P |
14:12:05 | kurzhaarrocker | But why? At first glance ape tags don't seem to contain any volume related info. Do I miss something? |
14:12:46 | LinusN | afaik, it's a special ape tag |
14:13:00 | preglow | ape tags har used for other files as well |
14:13:03 | preglow | musepack especially |
14:13:04 | LinusN | containing all info needed to reconstruct the original mp3 |
14:13:13 | preglow | har = are, yes |
14:13:14 | Bagder | afaik, the store undo info in the ape tag they add |
14:13:21 | Bagder | they store |
14:13:32 | Bagder | mp3gain that is |
14:13:56 | kurzhaarrocker | Ah, thats what they call "lossless" :) |
14:15:29 | amiconn | kurzhaarrocker: It is lossless as the mp3 compressed data isn't recompressed |
14:16:28 | kurzhaarrocker | You're right: I mustn't mix up "lossless" and "non destructive". |
14:17:47 | amiconn | splitedit.rock is also lossless in this sense |
14:18:58 | kurzhaarrocker | Hm. Some day I want spitedit to be destructive - maybe next millenium.... |
14:20:46 | preglow | to split in the middle of frames? |
14:22:28 | kurzhaarrocker | No. Now splitedit writes completely new files. That's not necessary. It could alter the fat, and prepend a sector to the tail file. |
14:23:08 | preglow | hahah |
14:23:29 | preglow | plugins that modify the file system = the shiznit |
14:24:29 | kurzhaarrocker | It's a question of the api. We could add a function that prepends a disc sector to a file. |

14:39:40 | Bagder | ripnetuk: curl has no recursive download! |
14:39:51 | ripnetuk | that would be why i cant find it :) |
14:39:54 | ripnetuk | thanks |
14:40:17 | ripnetuk | w shall use wget then |

14:41:27 | preglow | how'd you see the III_decode address, btw? you made it non-static? |
14:41:35 | LinusN | yes |
14:44:17 | ripnetuk | thanks guys... see ya soon (i keep up by reading CVS logs) cya |
14:44:20 | | Quit ripnetuk ("Leaving") |
14:49:49 | LinusN | hmm, the question is how we deal with cache issues in general |
14:50:39 | LinusN | perhaps add some section/linker magic to align code with the cache |
14:56:38 | HCl | screw this, where's my tablet :/ |
14:56:39 | preglow | would of course be nice if possible |
15:00 |
15:02:48 | LinusN | preglow: as a test: place III_decode and imdct_l in a separate section, .cachetest |
15:03:28 | preglow | yes, think i need to do that, relocating stuff inside libmad files was not very easy |
15:03:46 | preglow | everything's static, so they never declare their functions |
15:04:26 | LinusN | i have a patch, but it includes the entire imdct_mcf5249.S diff |
15:04:36 | LinusN | want it? |
15:04:51 | preglow | sure |

15:13:37 | preglow | you were most certainly in the right, linux |
15:13:43 | preglow | linuS |
15:15:45 | preglow | so, you think grouping all cache critical functions close is the way to go? |
15:16:04 | | Quit lostlogic ("Going to the moon") |
15:16:53 | LinusN | it's a good start |
15:17:08 | preglow | but yeah, i think it's on a level with the old imdct_l now |
15:17:12 | LinusN | keep all cache critical stuff in the same 8k block |
15:17:16 | preglow | even if i don't go above that, this is a good deal cleaner |
15:18:08 | preglow | it's 230% realtime at 320kbps |
15:18:13 | LinusN | man, this has puzzled me a lot the last couple of days |
15:18:32 | preglow | yes, you're not alone in having been puzzled, heh |
15:18:33 | LinusN | feels good to know what it was |
15:18:49 | preglow | today i learned a good deal about caches ;) |
15:19:00 | LinusN | 230% without dithering, i suppose |
15:19:20 | preglow | without dithering, yes, but i refuse to believe dithering should be a big showstopper |
15:19:30 | HCl | god i love my tablet |
15:23:54 | LinusN | ok, so now we have III_decode sorted out? no more tricks in your sleeve? |
15:25:06 | preglow | dct32 needs optimizing, but i wont do it |
15:25:12 | preglow | i'm so incredibly slow at doing that kind of thing |
15:25:20 | preglow | most kind of things, actually, but especially that kind of thing |
15:25:48 | preglow | i'll see if there's more to be optimized when i have time |
15:25:50 | preglow | which is not right now |
15:27:02 | LinusN | preglow: would a debugger help you? |
15:27:13 | preglow | hmm, i don't think so |
15:28:17 | preglow | how so, have you got one? ;) |
15:29:00 | LinusN | we can either get you a wiggler, or up the prio on the gdb stub |
15:29:59 | preglow | but no, i don't really think a debugger would help me much |
15:30:08 | LinusN | oki |
15:30:11 | preglow | it's fairly streamlined code |
15:30:24 | preglow | and i really shouldn't touch it further until summertime, heh |
15:31:25 | LinusN | ok, so how about committing it then? |
15:31:34 | preglow | can do, how about the cachetest stuff? |
15:31:39 | LinusN | without the cache test |
15:31:56 | preglow | ok, i'll just ensure things are up to snuff |
15:32:01 | LinusN | oki |
15:32:19 | * | LinusN has to go |
15:33:09 | preglow | yup, later |

15:33:57 | HCl | oh :/ |
15:36:45 | preglow | oh, bleh,i can push it above 230% with linus' fixes |

18:23:40 | HCl | nah |
18:23:45 | HCl | i was mostly lucky they let me swap it |
18:23:50 | HCl | cause technically, they weren't required to. |

18:28:04 | bobTHC | for samsung i'm barely sure |
18:28:47 | Lynx_ | i have never heard of a pixel going dead after buying the tft |
18:30:50 | preglow | people can ship displays with dead pixels |
18:31:02 | preglow | and dell isn't required to take this display back |
18:31:42 | *** | Saving seen data "./dancer.seen" |
18:31:52 | Lynx_ | aren't they required to take anything back? |
18:32:04 | preglow | i think they've got a limit on five dead pixels |
18:32:09 | preglow | before they're letting you have a new one |
18:32:32 | Lynx_ | it seems samsung is offering a zero pixel defect guarantee, but they just throw out all defect panels after fabrication. |
18:33:15 | Lynx_ | preglow: i meant the law that lets you send any order back within a few weeks, not lcd specific |
18:34:49 | preglow | Lynx_: ahh, i don't know if that applies after you've actually opened it |
18:35:34 | Lynx_ | preglow: well, it wouldn't make much sense if you could not even look at it. i have sent stuff back to amazon that was opened. |
18:36:59 | Lynx_ | you could also kill 5 more pixels ;) |
18:38:10 | t0mas | hmm... anybody here knowledgable about SSH? |
18:38:23 | preglow | hahah |
18:38:36 | preglow | i could of course try massaging these dead pixels and send it back when i have a hundred more |
18:38:49 | t0mas | preglow: they'll suspect something then ;) |
18:39:10 | Lynx_ | before you do that you punch a hole in the box and claim transport damage ;) |

18:39:38 | t0mas | the protocol basics or the usage? |
18:39:45 | Lynx_ | t0mas: usage |
18:39:47 | bobTHC | use |
18:39:52 | t0mas | ghehe |
18:39:56 | t0mas | yes, I know that too |
18:40:04 | Lynx_ | t0mas: i assumed that :) |
18:40:15 | t0mas | I need some info on the AES encryption thing used... |
18:41:06 | bobTHC | he encryption used by ssh can be either AES-128, 3DES, Blowfish, cast-128, ... |

18:41:33 | bobTHC | s/he/ |

18:42:27 | t0mas | encryption of the whole session? |

18:42:49 | t0mas | ok, not key exchange only? |

18:43:26 | bobTHC | to remotely send and receive files under the strong encryption |
18:43:29 | Lynx_ | t0mas: as far as i understand the whole session is aes |
18:43:44 | t0mas | ok, no switching... |
18:43:49 | t0mas | or AES isn't public key? |
18:46:19 | bobTHC | AES is symetric |
18:46:31 | t0mas | ok |
18:46:47 | t0mas | ehrm... how does it send keys? |
18:47:22 | Lynx_ | hmm, there is a transport layer and a user authentication layer... |
18:47:58 | Lynx_ | ah, it uses rsa / dsa |
18:48:54 | t0mas | ok |
18:50:10 | t0mas | just wondering... |
18:50:10 | t0mas | debug1: SSH2_MSG_KEXINIT sent |
18:50:10 | t0mas | debug1: SSH2_MSG_KEXINIT received |
18:50:10 | t0mas | debug1: kex: server->client aes128-cbc hmac-md5 none |
18:50:10 | t0mas | debug1: kex: client->server aes128-cbc hmac-md5 none |
18:50:28 | t0mas | kex = Key Exchange I guess... and it uses aes128-cbc for that.. |
18:50:36 | t0mas | so AES for keyexchange? |
18:50:54 | bobTHC | http://www.windowsecurity.com/articles/SSH.html |
18:51:25 | t0mas | tnx |
18:51:28 | * | t0mas is away: eating |
18:53:14 | bobTHC | there is no server key. The session key produced by Diffie-Hellman is used to encrypt the real session key.
