Enhanced performance of MAMEdev MAME in X11?!?!

mitu

@George said in Enhanced performance of MAMEdev MAME in X11?!?!:

One other question. On my other RPi devices (3b+, etc), when I launch a game from RetroPie and then go into the configuration, I have the ability to set the screen resolution and the frame buffer size. The frame buffer option is not available on the RPi 4, and the screen resolution options look like they are different too. Is this due to dispmanx not being on the RPi 4?

Kind of, the video driver (KMSDRM) has its own resolution handling (kernel modesettings) that doesn't allow setting arbitrary resolution; the list is read from the EDID info reported by the display and it's not possible to scale the viewport arbitrarily to a resolution (hence no framebuffer resolution configuration).

George

Just did a fresh install with the latest RetroPie 4.7.1. I ran the basic install in RetroPie Setup and did a system update through that as well. Then, after running Install Pixel Desktop, I checked for xserver-xorg-video-fbturbo and it was installed.

pi@retropie:~ $ dpkg -l | grep -i fbt
ii  xserver-xorg-video-fbturbo           1.20190107~114053                   armhf        X.Org X server -- fbturbo display driver

I found that it is in fact being installed when installing the Pixel desktop as evident from the logs.

I can remove it very easily with apt remove -Y xserver-xorg-video-fbturbo and I can add that to a script, but it can get installed again if someone installs matchbox (when they install Steamlink). What would be the best way to ensure that it doesn't get re-installed?

mitu

I see that xserver-xorg-video-fbturbo is recommended by raspberrypi-ui-mods, so that's why it's getting installed.

I can remove it very easily with apt remove -Y xserver-xorg-video-fbturbo and I can add that to a script, but it can get installed again if someone installs matchbox (when they install Steamlink).

Hm, I don't seem to be able to reproduce this. Steamlink installs matchbox-window-manager, that has not dependency on xserver-xorg-video-fbturbo.

What would be the best way to ensure that it doesn't get re-installed?

The package is just recommended by raspberrypi-ui-mods, I think removing it would be enough.

George

Thanks @mitu,

I'll have to retest the Steamlink setup to see if I can recreate what I was seeing. It also installs Xorg (of course), but it's also possible that I've been installing more than I remember.

I've been doing some further testing to see where the speed increase is coming from. From within the Pixel Desktop, I can run MAME with ddp3 or outrun at full speed without having to reduce the resolution before hand. It would seem to be that MAME will draw the screen at the game's native resolution and then scale it upwards as needed. Games without a native screen resolution don't get this enhancement though (like the Coleco tabletop arcade games), and will render at the full resolution of the screen when launched. Reducing the resolution before hand and launching the game shows a marked improvement, even more than what I see when running through Emulation Station and reducing the screen resolution. That makes be believe that X11 is able to access more of the GPU than the KMSDRM driver, even though they are both using OpenGL.

The audio seems to be the same, both using ALSA drivers, same sample rate, etc.

That's all I have for now. I'll update when I have more.

@George very curious stuff. can you try adding the -verbose arg to mame in both x11 and without? curious as to the output. certainly when we tried -video accel when testing your mame PR there was large performance increases, but i certainly wouldn't have got ddp3 full speed. see https://github.com/RetroPie/RetroPie-Setup/pull/2697#issuecomment-629698811

hopefully a verbose log should show us the difference between the two.

George

Thanks @dankcushions!

Yes, I actually tested ddp3 because you had tested it already and I wanted to try some comparisons. It was certainly unexpected. I also tested Tekken 2 and found that it ran at 66% in X11 vs. 50% in KMSDRM. I think the big difference with Tekken 2 though is that it's 3D rendering and the hardware uses a GPU which is probably being emulated in software. So there's probably a bit of a performance increase for rendering the final pixel output, but still a lot of overhead for the 3D rendering.

I have some verbose output from Outrun (because it loads up fast and I get a good idea of the performance pretty immediately). I'll have to run my tests again with ddp3.

The verbose output makes my post too long, so adding to multiple posts.

The environment variable setting (SDL_VIDEO_KMSDRM_CRTCID=87 SDL_VIDEO_KMSDRM_MODEID=24) in the second case is interesting. Maybe it is not MAME, but perhaps there is something going on with SDL when using KMSDRM vs. X11.

Will run ddp3 in verbose mode and post up results later.

I did a bit more testing, this time by SSHing into the machine and using tvservice -s. I found out some more interesting tidbits.

When running Outrun from EmulationStation with my monitor's native resolution (1680x1050). Performance is poor and tvservice -s shows:

state 0xa [HDMI CUSTOM RGB full unknown AR], 1680x1050 @ 60.00Hz, progressive

When I run it from EmulationStation with 640x480 resolution selected. Performance is great and tvservice -s shows:

state 0xa [HDMI CUSTOM RGB full 4:3], 640x480 @ 60.00Hz, progressive

Everything seems straightforward, until I then get into the Pixel Desktop, which is running at 1680x1050, and without changing the resolution, I run Outrun in MAME. Performance is great and tvservice -s unexpectedly shows:

state 0xa [HDMI CUSTOM RGB full unknown AR], 1680x1050 @ 60.00Hz, progressive

This seems to support my idea that when X11 is used, the pixel data is being rendered at the original machine's native resolution and then being scaled up by the GPU. Contrarily, when KMSDRM is being used, I believe something else is going on.

I'll have to take a look at the MAME and SDL source code to see if. anything pops up. Any other ideas are welcome!

@george thanks for this. i guess the difference is

Current Videodriver: x11

(fast)

vs

Current Videodriver: KMSDRM

(slow)

out of interest, in /boot/config.txt are you running

dtoverlay=vc4-fkms-v3d

(default, "fake" kms) or

dtoverlay=vc4-kms-v3d

(pure kms)

i wonder if the latter makes a difference?

George

@dankcushions yeah, the video driver does seem to be the difference, but I'm unable to determine how.

My config.txt shows the following:

[pi4]
# Enable DRM VC4 V3D driver on top of the dispmanx display stack
dtoverlay=vc4-fkms-v3d
max_framebuffers=2

I can check if pure KMS makes any difference.

Well that didn't take long. I switched to kms and MAME won't even run correctly from within EmulationStation. The screen blanks out and I can't get out of MAME. SSHing in and looking at the runcommand.log makes it appear that the game is loaded. From within X11, I can run the game, but when I exit out, the screen blanks out and doesn't come back. Interestingly, there is also no sound when running MAME on X11. Switching back to fkms and everything is back to normal.

While looking at the source for SDL and MAME, I noticed that the MAME repository also includes source for SDL. I also noticed that RetroPie has its own repository for SDL. Though I can't find in either any references to SDL_VIDEO_KMSDRM_CRTCID or SDL_VIDEO_KMSDRM_MODEID. Could there be a conflict? Am I not looking in the correct place?

Thanks!

@george our SDL code is on a retropie-2.0.10 branch.

The KMS driver for the current stable kernel (5.4) in Raspbian has issues. If you wish to switch to the (pure) KMS driver, you should also switch to the next LTS Rapbian kernel (5.9, soon to be 5.10), where the KMS driver should be working much better. See https://www.raspberrypi.org/forums/viewtopic.php?f=29&t=288234.

Those env vars are set by runcommand, to set the video resolution. It's a RetroPie local patch to be able to switch video modes with SDL2 based applications, since there was (at the time) no method to do so - the KMSDRM driver would report only the (fullscreen) current resolution to the application and mode switching would no be possible otherwise. Instead, based on those vars, SDL2 switches resolution on video initialization and reports the (new) resolution to the applications.

This kind of ties up with what you noticed.One of the important differences between the x11 and kms SDL2 video drivers is that x11 is able to switch to any resolution supported by the display - on the fly - while kms does not. Having said that, the KMS SDL2 driver has been radically changed in newer SDL2 version (since 2.0.10, the version that RetroPie includes and patched), but unfortunately those changes are not without issues so they haven't been included in RetroPie.

@mitu Sorry to hijack this thread but is this not one of the main reasons that people can't use on the fly resolution switching with vga666 and a crt?

@mitu Sorry to hijack this thread but

No, it's not related.

George

Thanks @buzz and @mitu!

This info gives me some good pointers to test. I can try the base versions of SDL (2.0.10 and the latest) vs. what comes with RetroPie (i.e. retropie-2.0.10) to see if there are any performance differences at all. I also noticed that there is some debug messages in the code, so perhaps I can enable debug logging to possibly get additional information.

Post that, I'll see if there's anything to be gleaned in how MAME handles (or doesn't handle) resolution changes.

Side note: I see some changes in the retropie-2.0.10 branch with SDL_sysjoystick.c that seem to be related in some way to a bug I reported to SDL. I'll have to check that out as well.

Thanks again!

Looks like I've hit a couple of snags while trying to compile. I modified the RetroPi sdl2.sh scriptmodule to pull from a different source/branch. I tried release-2.0.10 and release-2.0.12. I get the error message:

/home/pi/RetroPie-Setup/tmp/build/sdl210/2.0.12+5rpi/src/video/SDL_egl.c:289:53: error: 'F_OK' undeclared (first use in this function)
     SDL_bool vc4 = (0 == access("/sys/module/vc4/", F_OK));

And if I fix that by adding #include <unistd.h> I get the following error message:

/usr/include/GLES/gl.h:63:25: error: conflicting types for 'GLsizeiptr'
 typedef khronos_ssize_t GLsizeiptr;

But when I compile the retropie-2.0.10branch it compiles fine. Perhaps there are some hints in that branch that I can port over. Continuing to work on it, but any pointers would be helpful.

Thanks!
