#rockbox log for 2015-10-04

00:01:39jtdesigns01yep, right now i`m implementing getting the relative data
00:02:00[Franklin]jtdesigns01: for SW:DF?
00:02:27jtdesigns01though sw:df will definitely use it
00:03:25[Saint]you could do simple swipe gestures just by checking to see if you pass through the quadrants of the touchpad in a single gesture, though there's room for false positives there.
00:09:13[Franklin]how can I format a floating-point number in rockbox?
00:09:19[Franklin]%f doesn't seem to be supported
00:09:41[Franklin](for testing purposes, also, so speed doesn't matter)

17:57:46[Franklin]just one more think I don't know: what piece code responds the the host's polls?
18:03:01 Quit stickyb1t (Quit: Konversation terminated!)
18:03:44gevaerts[Franklin]: if you mean the once per frame (or whatever you set it to) polls, then the answer is "none"
18:03:48gevaertsThat's done in hardware
18:04:04 Join stickyb1t [0] (
18:04:39[Franklin]that explains it
18:05:03[Franklin]but how does rockbox give the host the interrupt data then? DMA?
18:06:59gevaertsDepends on the exact device, but on PP502x you tell the hardware about a bit of memory you put the data in. If that's there, the hardware will respond to the poll with it, if it's not there, the response will be that there's nothing
18:08:30[Franklin]so would that be what's happening in ep_send() in the as3525 driver?
18:09:02*gevaerts isn't familiar with the as3525 code
18:09:23[Franklin]it's a PP5022 core, I think
18:09:37*gevaerts promises it isn't :)
18:10:02gevaertsWhat device are you working with?
18:10:08[Franklin]sansa e200v1
18:10:18gevaertsThat's PP5022
18:10:21gevaerts*not* as3525
18:10:38gevaertsYou want firmware/target/arm/usb-drv-arc.c
18:10:45*[Franklin] isn't sure where he got as3525 then
18:11:00[Franklin]oh... e200v2 uses the as3525

18:53:11pamaury[Franklin]: I kind of simplified, as gevaerts said, everything is done in hardware, it's only the notification of completion that limits the speed because it goes through threading and is subject to HZ limit
18:53:47pamauryusb drivers tends to be quite complicated
18:54:24[Franklin]would it be possible to rewrite it without using threads?
18:54:45[Saint]The Clip(s) USB drivers drove me to madness at one point.
18:55:51pamauryas I said, the only workaround is to have the driver directly call a function, as done in g#1009
18:55:56[Saint]Oh. ANd N2Gs.
18:56:02fs-bluebot3Gerrit review #1009 at : 3Add USB Audio 1.0 support (EXPERIMENTAL) by Amaury Pouly
18:56:41pamaurybut then you have to be extra careful because the handler will be called from interrupt context so not every operation is allowed
18:57:15*[Saint] decides to work on intermediate scaling again
18:57:28[Saint]...though, honestly, I'm not entirely sure it makes a lot of sense
18:57:37[Saint]Well, it does on some targets.
18:57:42[Saint]Others, notsomuch.
18:57:47 Join chrisb [0] (
18:58:00[Saint]I have a tree here with the basics /kinda/ working...ish.
18:58:25[Saint]It touches damn near everything though. WHich is hardly graceful.
18:58:52pamaury[Saint]: what is intermediate scaling ?
19:00:18 Quit [Franklin] (Remote host closed the connection)
19:00:59[Saint]N clock levels between min/max.
19:01:10pamauryah frequency scaling
19:01:14*[Saint] nods
19:01:36pamaurythat would be useful indeed but the current code only knows about min/max :-/
19:01:47pamaurydo you think it's worh it though ?
19:02:35[Saint]...maybe. I mean, we have some VERY powerful targets, but, they also tend to be rather efficient at high clocks. So, ...
19:02:47[Saint]Mainly keeping me occupied. :)
19:04:39pamauryyeah that's true
19:06:36[Saint]The additional overhead from scaling might well wipe out any gains it could possibly bring.
19:09:40pamaurywell the thing is that changing the clock frequency can be costly

22:37:20*[Saint] is far down the rabbit hole
22:37:56[Saint]even "simple" scheduling is fairly complex.
