#rockbox log for 2008-09-07

00:00:17saratogasoap: its 3MHz per mA
00:00:34saratogaand base mA while idle at 30MHz is something like 30mA
00:02:04saratogaat 4v battery voltage
00:03:07soapWhich seems to indicate your MP3 work should save 12Mhz / 4mA on my iPod video, taking runtime from 16 hours to 17.9.
00:03:16soapDang that should be a nice improvement.
00:03:49amiconnsaratoga: 3MHz per mA and 30mA @30MHz means 20mA @0MHz
00:04:39saratogaamiconn: theres definately some components which draw power regardless of clock
00:04:52saratogaprobably things like the amps in the DAC, flash chips, DRAM, etc
00:04:55amiconnThat sounds reasonable; I think roughly half of that goes to the ram, and the other half to the audio codec
00:05:21saratogathe audio codec is rated for 40mw of output IIRC
00:05:23amiconnAt least that's what I measured on my 1st Gen ipod when experiementing with suspend
00:05:47amiconnI'm not talking about the output power, but about normal operating current (even without load)
00:05:48kugelsaratoga: why should I choose the e200v2?
00:05:53kugelI already have a e200
00:05:58 Part cfp
00:06:01saratogakugel: cheaper I think
00:06:17kugelbut the main reasons were: the scroll wheel, the better screen
00:06:25saratogathe screens different?
00:06:31kugelbut mainly the fact, that there's already enough e200v2 owners
00:06:40kugeland no fuze owner
00:06:48kugelsomeone needs to test the code on a fuze
00:06:51amiconnOn 1st Gen, the WM8721 draws around 8mA, the RAM about 13mA unless in low-power self refresh mode
00:07:12saratogasoap: theres some cost to turning on the extra core, but it looks very small if I've done my measurements right: http://www.duke.edu/~mgg6/rockbox/30mhz-2.png
00:07:32 Quit Davide-NYC ("ChatZilla 0.9.83 [Firefox 3.0.1/2008070208]")
00:07:47saratogaamiconn: next time I get my DMM out, I'll try doing measurements at different volumes and with the codec chip disabled and see what I get
00:07:50amiconnIn suspend (i.e. PP5002 at 32kHz and mostly sleeping, RAM in low-power self refresh mode, and LCD controler and DAC is standby mode) the whole box draws ~1.3mA
00:08:31kugelsaratoga: it's just, as a fuze owner I can contribute better to the port than as one more e200v2 owner
00:09:27amiconnThat's the same as the OF needs in suspend, and sucks a fully charged stock G1/g2 battery empty after about 920 hours (a bit more than a month)
00:09:35saratogasoap: feel free to battery bench your ipod and let me know if theres any improvement :)
00:10:00amiconnsaratoga: The patch should also work on PP5002 I suppose?
00:10:03 Quit Xerion (Read error: 104 (Connection reset by peer))
00:10:17saratogaamiconn: I don't know if dual core works on the PP5002 yet
00:10:17 Quit desowin ("KVIrc 4.0.0 Insomnia http://www.kvirc.net/")
00:10:22amiconnit does
00:10:25soapsaratoga, I'll need to BB the OF as well.
00:10:44soapI left my player on my dashboard the other day in full sun and fear for the battery.
00:10:44saratogathen it should, although you might need to move somethings into uncached DRAM instead of IRAM
00:11:02saratogai didn't check to see if I went past 48KB of IRAM when I allocated things
00:11:12amiconnCheck the .map ....
00:11:22 Quit mf0102 (Remote closed the connection)
00:12:17kugelsaratoga: the screen is definitely better then the e200v1 one, and I haven't read/heard that they also changed the screen on the e200v2
00:13:23saratogaamiconn: it goes 3KB over the limit, mostly due to the stack for the extra thread
00:14:01amiconnHmm. The stack can probably be in dram, as it's only used by one core
00:14:03saratogaand due to the need to duplicate a 2KB buffer
00:14:15amiconnI'd like to know how much that'd impact performance
00:14:27 Quit LambdaCalculus37 ("Do quit now, there's a demon around the corner!")
00:14:33saratogadoesn't the COP thread's stack get used a lot?
00:14:47saratogai thought thats were local variables were allocated
00:15:40amiconnIt is, but then the PP502x's cache is quite good
00:15:50amiconnPP5002 is another matter, unfortunately
00:17:33saratogai think the best thing to do would be to remove the synth code from IRAM, then shrink the size of the stack for the COP to whatever is actually needed and not the default, and then if it still doesn't fit put the duplicated buffer in DRAM
00:18:32 Join Nico_P [50] (n=nicolas@rockbox/developer/NicoP)
00:18:55amiconnWould also be necessary for PP5020
00:19:39saratogahow big is the main CPU stack?
00:19:52 Quit n1s ()
00:21:24saratogamight be able to put some of the extra 3KB onto there too
00:21:36saratogaanyway, I need to get some homework done

12:17:29jonseyi've a question
12:17:43jonseyi've created the rockbox.zvmboot
12:17:50jonseythan the nk.bin
12:18:10jonseyi've put the nk.bin with the hacked firmware uploader
12:18:27jonseybut wen the player start...i've always the same original firmware
12:18:35jonseywhy?
12:18:50jonseymy player is the ZVM 30gb
12:19:52linuxstbjonsey: I don't think many people know anything about the work on the zvm. I assume you've read everything in the wiki and the forum thread?
12:20:07jonseyyes

14:37:15linuxstbpetur: I don't think there's a quck fix - the apps code (and screens API) needs to use viewports fully. I would expect the apps code to always know what viewport is being used (because widgets are told to draw in a specific viewport), so there's no need for a "get_viewport" function.
14:38:52peturwell, this solution was the least work in the places where char_height & others were used ;)

14:58:08n1sgevaerts: my primary intention was to test on ata targets that could be cf modded to have the official bootloaders support the cf mod but it got sort of out of hand and I added more and more :) and bluebrother tested e200 so i guess only c200 is left
14:58:41*n1s would like some gigabeat f dev to look at the bootloader issues for that reported in the task
14:59:02gevaertsn1s: ok. I'll test c200, and I'll try to reproduce the gigabeat issue
14:59:30n1sgreat :)
14:59:48gevaertsI can also test a CF modded mini 2G (but that's exactly the same HW that bluebrother tested) and a 30GB video (5G)

21:10:13yeahxI never had problems with mp3 when I could use rockbox

21:10:23bluebrotherthe stuttering during playback has been fixed months ago.
21:10:58bluebrotherand for mp3 being slower than vorbis is simply because it isn't as heavily optimized as vorbis (yet)

If all sectors are written to the device contiguously, our driver will read those back without errors. If you write a whole partition with dd it might work too :-)

23:18:49linuxstbIsn't the X5 18bit?
23:18:59Bagderno, not real 18bit
23:19:13Bagderit's 16 too

23:20:47 Quit avis (Remote closed the connection)
23:21:08BagderI don't see why a target with 18bit shouldn't use 18bit
23:21:19kugelwell, it's probably up to the one who ports rockbox to a 18bit device first
23:21:20Bagderunless there a significant drawback in speed or similar
23:21:45linuxstbBagder: What do you mean by "not real 18-bit"? The LCD driver (lcd-as-x5.S) refers to RGB666...

23:23:24linuxstbI seem to recall the idea of using an 18-bit framebuffer for the x5 was discussed, but rejected. But I may also be recalling wrongly...
23:24:21amiconnlinuxstb: The HD66773 *interface supports 18 bit, and is configured as 18 bit in the X5
23:24:46amiconnHowever, the *internal memory* of the HD66773 is 16 bit only, so it dithers the 18 bit input data internally
23:25:16amiconnWe use this for video (as this internal dithering comes for free), but not for core gfx
23:26:18amiconnImo going 18 bit is quite a waste, so there must be a significant advantage to make it worthwile. Framebuffer data will double in size, as you'll need 32 bit for performance
23:26:29linuxstbDo you know about the HD66789R ? I think that's what we think the iaudio 7 is using.
23:26:58linuxstbI'm guessing that's 16-bit too?
23:27:02amiconnThe HD66789 is true 18 bit. In the H300 and colour ipods it's configured for 16 bit operation though
23:28:16amiconnI don't know about the hookup in the iaudio 7. The interface configuration is selected in hardware (by wirting of the selection pins), i.e. nothing we can change on the fly

23:29:55kugelamiconn: so, h300 could use 18bit?
23:30:04amiconnnope
23:31:08amiconnI could have used 18 bit if the iriver engineers had decided to configure it that way. But they didn't
23:31:14amiconn*It
23:31:29kugelAh, I understand
23:31:33markunthe gigabeat could use 18 maybe, if we set it to 24 bit mode it will use the upper 6 bits of every colour
23:32:22markunbut it depends on what the remaining 3x2 pins are connected to I guess
23:32:56amiconnGoing 18 bit doubles the size of all data in framebuffer format, and then 43.75% of that data is just wasted zeroes
23:33:34amiconnUsing 24 bit for the fb is probably even worse performance wise, although it wouldn't waste that much
23:33:41amiconnspace
23:34:04kugeland how about use 24 then? at least no wasted zeroes
23:34:12markunI think the 656 mode looks good enough, but people could experiment if they want of course

23:35:58amiconnI talked about using 24 bits/pixel in the framebuffer
23:36:24kugelcan't 18bit be used for the frame buffer?
23:36:54Bagderhow would that work?

23:40:25amiconnRegarding the i7, it comes down to the question whether the 2 extra bits are worth all the hassle and extra resources
23:40:55amiconnFor video, lcd_yuv_blit() can make use of the full 18 bits independently of core graphics
23:43:30kugelI'd like to have 18bit if possible. I've seen the difference between 16 and 18 on some pictures

23:46:22kugelaww, no gapless on the fuze
23:46:59markunI just hear from the guy behind iriver-t10.sourceforge.net that the T10 only has the 256K of SRAM and no SDRAM! Would it be possible to get rockbox running on it in any way?
23:47:31linuxstbThe Clip seems similar - about 384KB of RAM, but 256KB seems to be pushing it...
23:47:52kugelI think with Nico_P's patch it should be possible
23:47:55linuxstbMost of the Clip's firmware seems to be in the form of plugins
23:47:57markunlinuxstb: maybe by running the code from flash directly?
23:48:17markunkugel: which patch is that?
23:48:18amiconnWell, the neo also has just 256KB ram, and openneo is a fork of early rockbox...
23:48:33linuxstbBut that has a hardware mpeg decoder...
23:48:50kugelhttp://www.rockbox.org/tracker/task/9332
23:49:03Bagderand it was an OOOOOLD rockbox
23:49:05amiconnlinuxstb: That is a point, but not an excuse...
23:49:38Bagderand similar to nico_p's patch, it probably used next to no ram for buffering
23:49:44Bagdersince it had its disk spinning non-stop
23:49:52*amiconn often reminds rockboxers that making efficient use of resources pays off
23:50:25amiconn...even if at a certain point there's *apparently* not much use of doing so.
23:50:31bluebrotherBagder (and possibly others): any thoughts on FS #9372? Is this approach ok or do we want rockboxdev.sh being "simpler"?
23:50:40linuxstbThe DAX and M200 are also relatively low on RAM - 2MB.
23:51:04amiconnImho this is a key advantage of a dedicated embedded firmware like rockbox versus all those gadgets running linux
23:51:44Bagderbluebrother: I think that approach looks fine!
23:52:10bluebrothergreat. Then I'm going to commit this before leaving (hoping everything goes well ;-)
23:52:12Bagderamiconn: I agree with that
23:52:12amiconnIthink that a reduced-feature rockbox should be possible on such a low-ram, flash based target
23:52:36kugelbluebrother: is the space between needed? In linux cli options can be used together without a space between commonly
23:53:18kugelamiconn: I agree
23:53:18linuxstbGiven that plugins can be loaded very quickly, I would just see most features being split out to plugins.
23:53:44bluebrotheryes. Feel free to improve the for arch in $selarch ...
