WinUAE tools that use x86 dll

[FrodeSolheim]

@Der Wanderer I am now self-supplied with simple test programs, but I would like to test more real-world programs - specifically I want to test that the "WinUAE compatibility layer" (compatibility with the existing native interface) is actually compatible...

So if possible, I would appreciate a preconfigured test setup with synth.dll and something Amiga-side which uses it. I can then test that with FS-UAE for windows/x86 (*).

(*) Note, it will only work in FS-UAE as long as there is no WinUAE-specific behaviour. For example, if the amigawnd member of the "a6 struct" is used it will not work.

You'll also be happy to hear that the new interface is largely interoperable with the old. You can open a native library with the new interface and use the functions via the old - or vice versa. So one can for example port code over gradually to use the new async functions (or even keep using the old interface if so desired).

[Der Wanderer]

The reason why you want me to test this is also to see if someone else than you (and maybe Toni) is able to understand and handle what you fiddled out. Otherwise, there wont be much usage of this feature.

I will make you a small example, based on the tiny AmigaOS install I have sent you. If you want to hear the result of synth.dll, ahi will be required. I can set the samplerate to 16kHz, so you can use Paula driver for now.

[FrodeSolheim]

An example with paula output would be nice, as I wouldn't hear anything otherwise

The new stuff is not more complicated the the old stuff (a bit more complicated internally, but that's not visible to users of the feature).

uaenative.library implementation is more or less complete now, with async mode too - I have also created a simple uni-create-wrapper.py script which takes a native library and generates wrapper functions for ease of use. Here's how usage looks now:

Example native library:

#include "uni_library.h"
#include <stdio.h>

UNI_DEFINE_LIBRARY (1, NULL);

UNIAPI void UNICALL hello_world (struct uni *uni)
{
    uni_char *data = UNI_PCHAR_PARAM (d1);
    uni_long data_len = UNI_LONG_PARAM (d2);
    snprintf (data, data_len, "Hello World!\n\nBest regards, %s",
              uni->get_uae_string());
}

Example Amiga program using the auto-generated wrapper functions (wrapper name "hwlib" chosen when generating the wrappers - tested using GCC 2.95.3 cross-compiler for m68k-amigaos):

#include "hwlib.h"

static char data[128];

int main (int argc, char *argv[])
{
    if (!hwlib_open ()) {
        printf ("error opening hwlib: %lx\n", hwlib_get_last_error ());
        return 1;
    }
    hwlib_hello_world (data, 128);
    printf ("%s\n", data);
    hwlib_close ();
    return 0;
}

The advantage of using the wrapper functions, besides ease of use, is that you also get parameter checking due to having proper C function prototypes, and the arguments are sent through the correct registers automatically

(You can of course just use uaenative.library directly, more or less like the old native interface - except you perform library jumps instead of an absolute jump).

[Der Wanderer]

Here is a little test for the native DLL interface for WinUAE. It can be used to test compatibelity with the native Interface on FSUAE.

It gives me about 4 times speedup on this setup, some algorithms benefit more and some less. The test must be run several times to get a feeling for the actual speed, as it seems to confuse the timer.device when jumping to native code sometimes.

Installation:
The 68K "synth.library" goes to Libs:
The x86 "synth.dll" goes to to the path of your WinUAE.exe

There are two 68k executables to run under AmigaOS, one uses the 68K library, and one the x86 .dll through the WinUAE .dll interface.

[Der Wanderer]

The test program renders a wave sample that sounds like a bass string of a guitar using physical modelling of a bowed string.

Strangely, the native version adds some ringing oscillation to the sample as the delay progresses. I have no idea why that is. So somehow the float calculations seem to be different in WinUAE than in the .dll. This is really wiered. I tried lots of setting in Visual Studio influencing the float model precision etc. but nothing helps.

no hope that someone continuing QuarkText development?

[thellier]

>continuing QuarkTex development?

For what usage as Wazp3D almost do the same ?


QuarkTex do :
Warp3D.library to OpenGL32.dll wrapping (hardware accelerated)
agl.library (StormMesa) to OpenGL32.dll wrapping (hardware accelerated)


Wazp3D do :
Warp3D.library to OpenGL32.dll wrapping (hardware accelerated)
(in fact 1% of Wazp3D code come from QuarkTex source)
Dont wrap agl.library (StormMesa) but just use an updated agl.library (StormMesa2010) with less bugs (it call Warp3D.library so is somehow hardware accelerated too)

ah ok

Why is there no 64-bit version of soft3d.dll for use with winuae64?

[thellier]

Because I dont know what changes are needed to recompile it as a 64 bits dll
You know I am not a Windows coder so dont know all about this platform

thellier may be you upload latest sources of Wazp3D?

[thellier]

The latests stable sources are on Aminet in Wazp3D package

Then we did a "fork" with Bszili help for Morphos: those changes were never included in main source as it will have need to "merge" and "revise" the two versions to one and I didnt have the time nor motivation to do that

Certainly a new Wazp3D version will happen one day (that will correct the Wazp3D-Prefs bugs...) but I dont know when I will have time do do that

Is there a way that this stuff help to play amiga dosbox faster ??
or perhaps is it possible to make a midi.dll ??
Could it help to display html5 and things like that ??
Speed up internet browsers ??
What are the possibilities ???

EDITED: just think about it : could this trick be used for sdl libraries ??? it could be really interesting. Or png or 040 and 060 math libs ??? Sorry but i don't know the limitations of this stuff.

Again sorry for my noob question ! but please if you can give me a short answer.
I think about it because i would like to make an amiga like computer, hidding windows, but the big problem is youtube, java,etc...

[Zilog]

Hi,
i search of write x86 dll, but i have the problem:


A) for use "winuae_opendll" in amiga c program how file include this function?


B) When find ultimate winuaesupport.h


Thanks a lot for help.
