Try this.

Ok, just to confirm, the following does appear to work: void dcache_wbinv_all&#40;&#41; &#123; int i; for&#40;i = 0; i < 8192; i += 64&#41; &#123; __builtin_allegrex_cache&#40;0x14, i&#41;; __builtin_allegrex_cache&#40;0x14, i&#41;; &#125; &#125; (As d...

By the way, the latest incarnation of the MediaEngine prx is with the source for SNES9X_TYL 0.4.2 ME for 3xx. You can find an arc here: http://chilly-willys-ice-flow.googlegroups.com/web/snes9xTYL-0.4.2me_fw3x-src.zip ... J.F./crazyc: I've found something very unusual going on with the cache invali...

As far as building fast, generated code I imagine that profiling is your only route. While the generated code is entirely dependent on the ROM you're executing you can't escape the fact that you'd need to account for every ROM anyways. But I speak out of ignorance of Daedalus's internal workings so...

ME => MediaEngine

Aww, you've ruined the mystery now! :)

According to the MIPS R4k manual 'LL and SC instructions implicitly perform a SYNC', so this should be fine. However, the memory location must be cached for use with LL/SC, so I think the variable will need to live in a cache-aligned chunk of memory, and I'll have to insert some cache invalidation/...

Is this thread related?

I just wanted to chime in with my experience of optimising Daedalus for the PSP. The only reason Daedalus is anywhere close to being playable is from having a good dynamic recompiler. The PSP port wasn't really a case of optimising any high-level algorithms, or even converting any specific code to a...

enjoy ! ... Awesome -thanks. I'm assuming from crazyc's comment that this is only callable from the SC whilst in kernel mode, so I'd need to implement it in a kernel mode prx? I guess it would make a very useful addition to the MediaEngine.prx I've been using (courtesy of J.F.). ll/sc pair works on...

There was also this post from hlide talking about the 'SC/ME mutex'. At address 0xbc100048 on both cpus, there is a word mmio register that can only be modified by one cpu at a time. If it is set to 1 then the sc holds it and it can't be modified by the me and if it's set to 2 visa versa. If it's s...

I've been doing a lot of work recently trying to get Daedalus's audio processing moved over to the Media Engine. I've had a fair amount of success so far, but I still have some tricky issues to deal with regarding synchronisation with the ME. Specifically, the inability to use mutexes and semaphores...

jimparis: hmm, that sounds right! I didn't get any further with this, instead I borrowed a PC compatible webcam to solve the problem I was trying to use a ps3 eye for. but hopefully this will be resolved one day. as you say, libusb just isn't fast enough for 640x480x60x2... ah well. thanks for the c...

thanks for the quick reply :) the 4160 byte packets dont look much like image data sadly :( the 12 byte packets are odd - here are some, 1 line per packet &#91;0000&#93; 0C CE 43 ED 0B 02 EB F1 1B 02 36 07 ..C.......6. &#91;0000&#93; 0C CE F3 2D 1B 02 85 2C 2B 02 57 07 ..........W. &...

got a bit further... I found that bulk_in was failing with 'invalid endpoint 0x01' according to libusb; so I tried endpoint 0x81 and it started succeeding. however the first call to bulk_in sends back 135232 bytes of image data - not enough to trigger your code to see a full frame. in fact that data...

hi jimparis, thanks for this work! I managed to compile your code with minimal changes on win32 using libusb-win32, after creating the necessary windows .inf files etc. it finds the device ok, however usb_claim_interface fails with error -22. after a bit of googling it seems that on win32 you need t...

I'm confused as well, since the possible flaw described above should be independent of any other texture changes - but only depend on the total number of different characters you use in your application. (Which BTW confuses me as well, since the standard intraFont cache size should be able to handl...

I wouldn't assume it's doing anything clever. It could just be unoptimised (or poorly optimised) code generated by the compiler: void blah&#40;&#41; &#123; char buf&#91;4140&#93;; //sprintf&#40; buf, "in blah, about to call foo&#58; %s", some_other_stuff &#4...

There seems to be another issues relating to caching when drawing lots of text. I get a lot of 'noise' as Daedalus's UI is rendering lots of text. Just for narrowing down the cause: have you tried INTRAFONT_CACHE_ALL or INTRAFONT_CACHE_LARGE when loading the fonts with intraFontLoad? ... If those f...

There seems to be another issues relating to caching when drawing lots of text. I get a lot of 'noise' as Daedalus's UI is rendering lots of text. Notice the text for 'Boot' and 'Country' in the two screenshots below: http://img86.imageshack.us/img86/706/sd0020rx9.png http://img232.imageshack.us/img...

What am I missing? Can I not mix indexed and non-indexed textures? That's my first guess, too. BUT, I'm by no means a GU-expert: the intraFont rendering stuff is pretty much identical to that of pgeFont. So you shouldn't rely on my opinion, but hopefully get a reply from someone who knows/wrote thi...

I am finally getting around to trying out your library. My project is using GU_PSM_8888 textures. When I tried to add in your library the text displays fine but everything else is rendering wrong. Before rendering my other content, I made sure to set sceGuTexMode, sceGuTexFilter, sceGuTexWrap, and ...

I spent two hours trying to track down that bug (causes graphical glitches in rare cases), but just couldn't find it. It just didn't occur to me to look there... Thank you for checking the code and reporting this bug! No problem at all - I'm pretty sure I'm going to switch Daedalus's text rendering...

Another small bug: float intraFontMeasureText&#40;intraFont *font, const char *text&#41; &#123; if &#40;!font&#41; return 0.0f; int i, length = 0; float x = 0.0f; while &#40;&#40;text&#91;length&#93; > 0&#41; && &#40;text&#91;length&#93; !=...

I'm working on getting this into the SDK. It was time for a pspFont library. I think this would be fantastic. Question to the SDK maintainers (and others if they want to give their opinion anyway ;P): Should pspFont library be low-level and only provide the ability to render the glyphs or strings i...

This is really great - thanks. There is a bug in the call to sceGuDrawArray though. It's passing in twice as many verts as it should do for GU_SPRITES: sceGuDrawArray&#40;GU_SPRITES, GU_TEXTURE_32BITF|GU_COLOR_8888|GU_VERTEX_32BITF|GU_TRANSFORM_2D, &#40;n_glyphs+n_sglyphs&#41;<<2, 0, v&a...

Cheers J.F. - I'll check that out.

J.F.: In your DisplayTest sample (thanks for this by the way - it's excellent), the prx has the following module declaration: PSP_MODULE_INFO&#40;"MediaEngine", 0x1006, VERS, REVS&#41;; I appreciate that the 0x1000 flag is for kernel mode. What does 0x6 signify? I can't find any d...

The depends script wasn't working under OSX either - it needs to look for libncurses.dylib. I wrote a bit about it here.

Checking for /usr/include/ncurses.h should work too.
