Idea for an optimized Emulator
Dont know if its realy qt moko related but hey the emulator can maybe used in qt moko too :). Hi guys, I'm trying to port a snes emulator to the pandora. The problem is that around 60% of the cpu time is taken at 30 FPS by sending the data to the glamo. There is an optimizing idea from a very clever guy who has coded and optimized some emulators for arm devices. The basic idea is to split the bus between glamo and cpu so that the cpu has some work todo while the bus is blocked by the glamo. Like: cpu gets a short time to get data from the RAM into his cache. glamo takes the bus for a short time an gets data cpu cant access the bus and works with the data in his cache. cpu takes the bus back glamo works with the data in his cache [...] Would this be possible? Can you do it without knowing assembler and from a normal C programm? Or do you have to hack the kernel for it? Here is the chatlog: (01:10:28) emulator developer: Anyway, DMA occurs on the SoC itself, so it's possible to perform it from and to anything on the bus, presumably. (01:10:36) emulator developer: It was already shown to work with the Glamo. (01:10:47) emulator developer: Albeit at much lower bandwidth than expected. (01:11:03) emulator developer: The problem is, if you try to DMA one large chunk at a time the DMA ends up stealing the bus for that entire duration of time. (01:11:04) me: but the cpu can work during the DMA operation or? (01:11:36) emulator developer: As soon as the CPU ends up requiring the bus due to a write buffer writeback or cache miss/uncached access it'll end up being stalled until the DMA finishes. (01:12:18) emulator developer: But since the DMA can be set up to step in small chunks it's possible to make it not stall the bus for long, meaning you let the CPU access the bus without a lot of wait and then the CPU can go on doing other things. Since the CPU doesn't need the bus 100% of the time it can still get work done. (01:12:59) me: as long as there is some work todo inside the cache or? (01:13:22) emulator developer: There's always work to do inside the cache. (01:14:24) me: ok but when the glamo uses the whole bus. the cpu can finish its work inside the his cache and then wait until the bus is free or? Or did I misunderstood you? (01:15:29) emulator developer: The Glamo won't use the whole bus if the DMA is staged like I described. (01:15:39) emulator developer: It'll give other things a chance to use it. (01:16:12) me: trying to understand what you described (01:17:37) me: do you send only a piece of the frame at one time to the glamo so the bus isnt used 100% by the glamo? (01:17:58) emulator developer: A timer is set up to automatically do that. (01:18:34) me: hmmm ok (01:19:05) me: and then the cpu has his cache and keep working, and the glamo gets his data and when it's there then he swaps the buffers. (01:19:17) me: ok if i understand it right, it sounds like a realy good idea :) (01:20:04) emulator developer: Someone else mentioned it once. But it hasn't been done, sooo.. (01:20:23) me: so it would be kernel hacking... (01:20:34) me: or can we do it from a normal programm? (01:22:04) emulator developer: I don't know. (01:22:11) me: hmm ok (01:22:25) me: but your idea seems to be realy promising (01:23:32) me: are you sure it would work this way? if it would be possible it would realy help other game too :) (01:24:57) emulator developer: No, am not sure. (01:25:07) emulator developer: And I'm not going to develop on a Freerunner, so count that out ;p (01:25:18) me: *g* (01:25:27) me: i never expected you would develop something for me (01:25:49) me: im sorry that it sounded like i was searching for a nice guy to exploit so he is writing something i want for me (01:25:57) me: in the first post of the board (01:27:28) me: i learned much. i know now that the glamo bandwith is the problem, that the cpu is blocked when the glamo is getting normal data. and the you can bypass the problem if you use DMA and take care that the cpu and the glamo share the bus in a way that both have enough data in their cache to work (01:29:32) emulator developer: But it's a compromise. (01:29:44) emulator developer: It's not like you'd ever be able to do 60fps or anything. (01:29:49) me: thats fine (01:36:09) emulator developer: You'd be frame skipping. (01:36:19) me: thats ok (01:39:21) me: what you would think can be reached? (01:39:51) emulator developer: Dunno. (01:40:19) emulator developer: BTW, there's no OGL ES on Freerunner. (01:40:31) emulator developer: The Glamo has hardware capability for it but no drivers. And the company went under. (01:40:37) me: a (01:40:40) me: damn NDA (01:40:41) emulator developer: But never publicly released a datasheet. (01:41:02) me: ok it can play mpeg4 movies (01:41:04) me: thats cool (01:41:14) me: but the way it was placed on the freerunner realy sux (01:41:46) emulator developer: Yeah
qi-bootmenu-0.1 problem with menu
Hi, i use latest qi-bootmenu v0.1 for my GTA02 but i have a strange problem. When i powerup my Freerunner and than press AUX to start the bootmenu it always shows the big openmoko logo and starts the bootmenu. But it doesn't always show the possible bootable partitions. I tried it 15 times and in 7 cases it shows all three bootable partitions on my sd-card. In the other 8 cases it only shows poweroff in the bootmenu. And the cases when it worked and when not seemed randomly distributed. Is this a bug or do i have to do something else to get it working all the time? I have three bootable partitions with ext3 on each of them on my sd-card (shr-u, debian, gamerunner).

Re: [wikireader] Project Gutenberg (again)
Sean, thanks for your quick reply. 1) Is there a deep reason why boldface fonts are not implemented? I figure they are not really relevant for wikis, but would be nice for some of the books. Unless there is something that complicates the matter I'm not seeing, I think I will add them (should be straightforward to mimic the behaviour of italic fonts?). They are implemented. We just didn't include them to save space. (Font sets are super huge when you include all the unicode characters!) If you look at the function handle_data within http://github.com/wikireader/wikireader/blob/master/host-tools/offline-renderer/ArticleRenderer.py you'll see what I mean. Hm. I thought I had convinced myself that the real problem was that only two bits are used to encode the font id, and they are already used up (default, italic, title, subtitle, and supplements [large files with all characters I suppose] for default, title, subtitle). So adding boldface fonts to the wiki-app *does* seem to involve some non-trivial work. (I guess the advantage of splitting the fonts like this is that the small subset can be kept in memory all the time? The size of the fontfiles themselves is on the order of megabites so shouldn't matter, should it?) Sure we can do this. No problem! The font is getting more and more complex since we actually hand make many of the characters now. That would be really awesome. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
