Final point, as I'm sure someone will probably ask. Which 3D stuff do I want to run? Honestly, I'm confused as hell by all the different components and what you need to be able to do what. Any graphics coding I ever did so far was either SDL1 or Raylib. So all this OpenGL, MiniGL, OpenGLES, Warp, WarpNova, WarpSuperDuperNova++ is all just a complete mystery. Right now, I'm trying to test GLFW by afxgroup. On qemu with Radeon HD driver 3.x on R270x the demo "triangle_opengles2" runs, everything else crashes. Obviously everything crashes on Qemu with SM501.

If you've got a Radeon R7 270X working with qemu, then you should be able to use modernish OpenGL. Have you tried running known working 3D games? For example: Spencer Demo, or voxelnoid.

The Voodoo3 is very old, and will be restricted to OpenGL v1.3 (roughly) via MiniGL. So, it would be a big step down from your R7 270x.

It does matter. The point is this is a repo that apparently builds and works which implies I’m doing something wrong. If it turns out that the examples are known to not work then sure, I’ll look at them and submit a PR but first step is clib2 version of ogles2 and see where that gets us.

It's a good question if the example is supposed to compile as-is. I suspect not, though.

My preference would be for glfw3 to include an autoinit stub, so that it's loaded automatically.

What of those CompositeEngine can't do ? Blending, fading, scaling, rotation and duplication for sure can, and all the other stuff too ?

As written, the compositing engine doesn't do stuff like contortion, blurring, etc. It's theoretically possible to write code to do all those things using CompositeTags(), though.

It doesn't matter. The reason for those errors remains the same. Either you have an autoinit stub library that sets up ogles2.library for you, or you have to write that code yourself.

@MartinW

IOGLES2 is the ogles2.library interface pointer. You clearly haven't opened the ogles2.library and got its "main" interface. Ideally, there would be an autoinit static library that would do it all for you, but I don't think one exists. Maybe that could be added to the glfw3 port for convenience?

Anyway, you need to do something like the following:


#include <proto/exec.h>

#include <proto/ogles2.h>



#define MIN_OGLES2_VERSION 3



struct Library *OGLES2Base = NULL;

struct OGLES2IFace *IOGLES2 = NULL;



BOOL openLibs() {

    const char *libName = "ogles2.librbary";

    unsigned minLibVer = MIN_OGLES2_VERSION;

    OGLES2Base = OpenLibrary(libName, minLibVer);

    if(!OGLES2Base) {

        printf("Couldn't open %s version %u or higher.\n", libName, minLibVer);

        return FALSE;

    }

    IOGLES2 = GetInterface(OGLES2Base, "main", 1, NULL);

    if(!OGLES2) {

        printf("Couldn't get %s's main interface.\n");

        return FALSE;

    }

    return TRUE;

}



void closeLibs() {

    if(OGLES2) {

        DropInterface(IOGLES2);

        IOGLES2 = NULL;

    }

    if(OGLES2Base) {

        CloseLibrary(OGLES2Base);

        OGLES2Base = NULL;

    }

}

NOTE: I'm assuming you're compiling with __USE_INLINE__ defined. Otherwise you need to add IExec-> in front of the OpenLibrary() and other exec.library calls.

Your code should call openLibs() at the start of main(), and closeLibs() on exit.

Hans

P.S., The ogles2.library isn't newlib or clib2 specific.

@geennaam

I just tested bboot, and booting on my system is now down to about 23 seconds. It has the added bonus that I can update the kernel modules without needing to start the emulator, upload the new files, and reboot the emulator again.

Good enough for now...

A laptop with a Core-i5 1135G7 should give similar performance to my system. The raw CPU emulation speed is good. It's the gfx part that is a bit slower.

Okay. My line of questioning is trying to gauge whether the slowness is my specific hardware. The answers I'm getting tend to be generic emulation issues, whereas I'm looking into whether my system's slowness is simply the result of a slower machine, and how much of a boost upgrading would bring (money is tight, so I'm not going to upgrade on a whim).

I have upgraded to the latest release candidate. No performance change so far. I'll try bboot next. Right now, loading the kickstart modules takes about 12 seconds, which is longer than your total boot time...

Is it universally sluggish for everyone using emulation? Or is it my older laptop?

Bear in mind that I'm used to real hardware (X5000 & A1222), so I'm used to the system being fast and responsive.

As long as nvram isn't supported and you can't use U-Boot variables like peg2ide_xfer (or something similar) to configure the AmigaOS IDE driver to use UDMA it's only using slow PIO transfers.

I completely forgot that the old IDE drivers defaulted to PIO mode. Shows how long it's been since I last used an A1-XE...

If balaton is right about the nvram.config files, then IDE DMA should be enabled on my machine. The kicklayout has nvram.config included, and peg2ide_xfer=FFFF.

@all

Finally got round to trying out m3x's beta driver. The boot time drops down to about 38s, and there's no more long black screen delay at the start.

The system still feels sluggish, though. Odyssey takes about 18s for initial start after booting (drops to just under 5s on second run).

So its "compositing window manager" is not the feature of only Radeon cards, but also of Nvidia ones too ?

It isn't a graphics card feature at all. The compositing window manager literally uses the 3D GPU for compositing.

On AmigaOS 4 it only works on Radeon cards, because nobody went back and updated the drivers for older graphics cards (assuming thy have a capable enough GPU).

Quote:

So, theoretically, all this "compositing window manager", should be just done in the Warp3D, and be used by the system. That probably why one of Frieden brothers (Hans, if i remember right), wrote that they wish to use Gallium3D for compositing engine. So to be kind of the same on other OSes, and so be able to use it more easily maybe and not bother with CompositeTags or whatever..

You should be able to do compositing effects with Warp3D. They decided that the best option for OS 4 was to add a new function to the graphics.library. I don't think they'd drop CompositeTags() for Gallium3D. Rather, all graphics acceleration would go through Gallium3D.

Quote:

I think it was created to be just the same Compositing window manager as on other OSes, just where to make a feeling like something OS4 specific only :)

I mean, what it do, what all other compositing window managers can't do ? Or, what it can't do, what others can do ?

I doubt it was created to "make a feeling like something OS4 specific." They needed a way to make it work, and AmigaOS didn't have a modern 3D graphics system ready yet.

Quote:

No no, what i mean is that CompositeTags have a tags, for have a scaling, and in the includes fo compistetags,i find that only "lenear" kind of scaling is implemented (in hardware).

I.e. in E-UAE, LiveForIt made a 640x256 low-res resolution looks scalled in fullscreen on 1920x1080 : but scaling can be of different algos, linear, bilenear, with some effects on top like x2 and so on. With CompositeTags, we seems to be forced to one, plain kind of scaling called linear (i.e. basic).

The fact that we can do scaling with CompositeTags, it is probabaly comes as bonus, not as the main feature of it, right ?

Ah, ok. CompositeTags() can do (bi)linear and "nearest" filtering. I don't think cubic, sinc, & lanczos could be hardware accelerated at the time.

Quote:

But then, it is the same for any OS, right ?

Yes.

I think that the name "compositing engine" is just emphasis on the fact that it's a specific piece of software that can be enabled/disabled to provide hardware accelerated effects to workbench.

There is a lot going on behind the scenes. The "compositing engine" needs to detect when a partially transparent window changes (either in size, position, or contents), and then redraw that part of the screen. It tries to do this during the vblank interval so you don't get ugly partial redraw artifacts.

@kas1e

The compositing API is basically one function: CompositeTags()/CompositeTagList(). It wasn't created for Radeon cards specifically.

The composited window effects (e.g., the transparency and drop-shadows) are done using CompositeTags() on AmigaOS 4. I have no idea how it's implemented on MorphOS. AFAIK, Windows uses Direct-X to do the hardware-accelerated compositing effects.

I assume that CompositeTags() was created with implementing a composited window manager in mind. What's great, is that it's easily accessible for any developer to use. It's also designed to do a lot more than basic window transparency and shadow effects.

Quote:

Also, as far as i see in the docs, the only one method is used for the scaling : linear filtering, other ones didn't implement. That also correct ?

BitMapScale() is a very old (pre-OS4) scaling function that may not even be hardware accelerated. Use CompositeTags() instead.
