The codebase sets up ogg_int32_t, etc, but then uses long directly in several structures. Unfortunately for me longs are 64 bits on my platform, not 32, and I end up getting hammered by unnecessary software math routine calls. Should I be able to just search/replace 'long' with 'ogg_int32_t' in the code or would that cause more problems than it fixes? -Dave --- >8 ---- List

Can anybody point me at any resources that would explain how to optimize mdct_backward for a cpu with a fused multiply-accumute unit? >From what I understand from responses to my older postings, Tremor's mdct_backward could be rewritten to take advantage of a muladd. My target machine can do either two-wide 32x32 + Accum(64) -> Accum(64) integer muladd or eight-wide 16x16 + Accum(32)

Hello, I'm part of the (sadly fairly small) community of PS2 hackers. The current cross-toolchain for the PS2 is based on GCC 3.2.3, an outdated and buggy compiler, which I have personally gotten tired of working with, so I would like to port Clang as a newer cross-compiler for the PS2. However, the PS2 has some notable quirks which make this a non-trivial task for the current compiler. It

I spent a fair amount of time optimizing tremor for the PS2, mostly by using dual-pipe multiplies in the X[N]PRODnn and the window apply code. Then, just for kicks, I re-enabled _LOW_ACCURACY_ and lo and behold it was still substantially faster. I also got some gains out of tremor by changing the longs in cookbook and sharedbook to ogg_int32_t's like I did for vorbis. I think _LOW_ACCURACY_

you can write your own software mixer that can decode MP3 on the PS2 so I can't see why you can't do that with ogg, however, even mp3 is processor intensive and programers are not going to give up that much processor power which will decrease or detract from the rest of the game. However, I'm sure there are some people out there that have been able to work around this. Regardless, ps1

Hi, Sometime ago i finished a port of Ogg Vorbis to Playstation 2. The code is working just fine and the music sounds like it should, but there is one problem. I get CPU usage that looks like this (when i say frames i mean actually rendering frames on the Playstations 2 and you have 50 or 60 frames per second) cpu usage: ~100% ~0% ~0% 0% ~100% current

I just tried this, but the compiler still crashes with the same error. Maybe our experiments were different. To make

Hello, I hope it is ok to come here for a little help. I use _Samba Version 4.5.12-Debian_ on a _Linux serveur 4.9.0-4-amd64 #1 SMP Debian 4.9.51-1 (2017-09-28) x86_64 GNU/Linux_.

I checked out the lowmem-branch of Tremor from CVS but some files like synthesis.c seem to be missing on that branch. What am I doing wrong?

I should hope that there is trouble, since "type III" is an undefined concept for a Cox model. Since SAS Inc fostered the cult of type III they have recently added it as an option for phreg, but I am not able to find any hints in the phreg documentation of what exactly they are doing when you invoke it. If you can unearth this information, then I will be happy to tell you whether

Hi, I know this isn't a supported platform or anything, but I'm trying to get Samba 2.2.5 going on my Playstation 2 (mipsel-linux). There's an RPM for 2.0.something on the PS2-Linux CD, but I'm always a fan of running the latest version. It compiles okay, as long as I specity ./configure --host=mipsel-linux (not "--build=mipsel-linux" for some reason, like most

Hi there. This patch changes the block selection to quantify error based on the sum of the squared differences of the pixel values rather than the sum of the absolute differences, the former conventionally and statistically seeming like the preferable thing to do. The patch also const'ifies some parameters (which doesn't affect code quality on recent GCCs but might help on older/ other

Hello lists, I wonder, is there a way to remove a PS/2 keyboard from a guest and leave it only with USB bus one? Problem is that if i edit guest (via virsh edit) and change keyboard bus from ps2 to usb, I end up with two keyboards: ps2 and usb one. --

Hi all, Last year i was mentored by Chris Lattner at GSoC and i created the Mips back-end for LLVM. The back-end is still experimental (working with simple benchmarks only) and this year i would like to improve it as my GSoC proposal. Mips is still fairly used nowadays in a lot of devices - routers, wireless cards, PSP, PS2 - and it would be great to have a stable mips backend for LLVM. General

Hi. I'm trying to get this PS2 ISO generator to work. It requires the DLL:s mfc42.dll and mfc42loc.dll---hence I got them and placed them in ~/.wine/hdd/windows/system. Now it's complaining about missing .so libraries for the builtin DLL:s. I have this in the config: "mfc42" = "builtin, native" "mfc42loc" = "builtin, native"

Hello All, Am having some trouble computing Type III SS in a Cox Regression using either drop1 or Anova from the car package.
