Low framerate on main EmulationStation menu - Pi 4

[stoo]

the only time when my temps increase to eye popping levels is during code compiles rather than the emulators I normally play.

The GPU just doesn't seem to generate that much heat. Maybe if we had a FurMark equivalent or something it would, but under normal operation, even with the frequency locked high, it seems fine.

As you say, the only time the fan on my Argon ONE case actually comes on is during compiles. Even then it tops out at around 56c (and this is with the Pi4 oc'd to 2GHz).

@BuZz installed your mesa module without issue. One thing that can be done to possibly cut down on the build time/size of the mesa libraries is to just pass the needed Gallium drivers - v3d,vc4,kmsro for the Pi platform. Drm and surfaceless are default as well, so you also can just pass x11 for -Dplatform argument. I am glad to see a module that brings the latest and greatest from mesa on the pi platforms.

I don't have any experience with Debian packages so I've grown accustomed to just installing things through source.

Unfortunately, as am sure you are aware...the upstream mesa drivers don't resolve the topic of this thread (I wasn't expecting as much though just based on what I've found to be the cause personally). I also have SDL2 v2.0.12 installed on my Pi 4 and that also does not solve this issue either. I've seen that upstream "v2.0.13" has a lot of changes to the KMS/DRM driver so I guess its a wait and see approach there.

https://github.com/raspberrypi/linux/blob/rpi-5.4.y/drivers/gpu/drm/v3d/v3d_drv I believe this is the source of where the issue lies but I don't much time as of late to go through it.

@bluestang Upstream changed the debian rules around a fair amount - I built with everything as it's easier to maintain and wanted to keep my rules patch minimal (See history - and meson array changes).

Current SDL2 master doesn't work at all currently on the RPI4 (the atomic code isn't supported - related to EGL_KHR_fence_sync). I plan to do a ticket upstream.

Is this just a Pi4 issue or does it affect all Pis? I did learn this the hard way, so I ended up going back to v2.0.12 release.

Don't know if this will help, or be beneficial at all to anyone at this point; but if you're still in this position, I hope this post will help you.

I have a 75" LG TV with an Rpi4 box, the tearing was pretty awful (but I never saw this problem with my previous Rpi3 box.)

Here is what I did, and followed is my configuration which seems to have done the trick.

sudo apt-get install libgles2-mesa libgles2-mesa-dev xorg-dev

Here's my config file

[pi4]
cpu_freq=1800
over_voltage=5
gpu_freq=700

[all]
dtoverlay=vc4-fkms-v3d
gpu_mem=128
hdml_drive=2
hdmi_group=1
hdmi_mode=76
dtparam=audio=on

No turbo flag, cpufrequtil or things like that. Short and simple config file.
Emulationstation shows no lag between screens, games play without tearing.

I'm sure the config file can be improved upon, or my flags aren't 100% correct and are open to criticize, or maybe the drivers weren't necessary---but in the offshoot someone is still looking for answers, I hope this helps none the less.

Good luck!

[Kestrel42]

@mtucker6784 I am running a 4 GB Pi4 B and this certainly made a noticeable difference, thank you.

I didn’t make any other changes except this.

I am using a retroflag NES case with the SSD cartridge on a 65” 4K tv.

Have you checked out SDL2 v2.0.14 and the 5.10.2 KMS driver? Everything seems to be working AFAIK. Considering that 5.10 is the next LTS for RPiOS that is good news.

The PulseAudio update kinda came out of nowhere, but with the KMS audio driver it is playing nice.

The 5.10.2 FKMS driver has a nasty screen tearing issue that will never be fixed. The current roadmap has the RPi4 ditching FKMS entirely.

[paddydukes]

Here's my 2c. I also have a 65" LCD tv. I am using the retropie exclusively for games. I was getting crazy low framerate in the main menu, and more worryingly in games. It turned out that the PI was detecting the 4k capabiltiy and autodefaulting to that mode.

I set it to output in 720p, set the TV to detect the resolution so that it adapts to etc. in game.

I am setting 16 bit consoles to runahead 2 frames. So far I've not noticed any tearing or slowdown in SNES and SEGA. I don't really play NES but can test. I haven't noticed any tearing in alphaneo.

I do notice some tearing in N64 and Dreamcast. Mostly in Redream though, and it is experimental. Still, it's the best Dreamcast emulator IMO.

I added comical notes to my config. Edited to remove some unnecessary settings that were the result of incremental change and experimentation:

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
disable_overscan=1
# uncomment to force a specific HDMI mode (this will force VGA)
# Set to 720p 60hz
hdmi_group=1
hdmi_mode=4
#OVERCLOCK
# Up voltage
over_voltage=6
# Arm at 2
arm_freq=2000
# read loads of shite saying that you should edit v3d directly. It capped me at 500. Changed gpu_freq, boom 700. So I guess don't believe everything you read
gpu_freq=700

@bluestang I would like to do an experimental build on a different card. I couldn't find good simple instructions on using the KMS driver. When I tried to set the dt_overlay to kms as per online instructions it would fail to boot. If I removed the hdmi cable I could SSH in, but reconnecting it wasn't detected by the TV. Soon as I revert it is detected again. Wasn't sure if I was missing drivers or what I had to do to get them.

Also I've been noticing a few random crashes and reboots, so I might reduce some of the current overclock.

First and foremost you need to run the latest kernel by running sudo apt update && sudo apt full-upgrade -y.

There are additional steps that you need to do to set up the KMS driver but first let's address your /boot/config.txt:

gpu_freq sets the core clock for various blocks in the gpu and is not recommended anymore.
Change gpu_freq to v3d_freq=700.
I also set the minimum v3d freq to 500, v3d_freq_min=500 but this is completely optional.
gpu_mem is also not a setting needed for the Pi4 either, you can delete this alltogether.

Proper overclocking documentation can be found here. Make sure that you are using an adequate cooling solution when overclocking.

Now there are 2 distinct configurations you can use from this point forward w/ KMS:

1. KMS w/ Broadcom Audio:
dtoverlay=vc4-kms-v3d,noaudio **AND** dtparam=audio=on in /boot/config.txt
***This uses the KMS driver only for display and uses the Broadcom firmware audio driver***
***dtparam=audio=on must be placed before dtoverlay=vc4-kms-v3d,noaudio or else you will have no audio!!!***

If you chose option 1, you can reboot after you have edited the /boot/config.txt file with the necessary changes.

2. KMS w/ KMS Audio: 
dtoverlay=vc4-kms-v3d ***AND*** dtparam=audio=off or commented in /boot/config.txt
***This uses the KMS driver for display and audio and disables firmware audio, however, it requires more files to be edited to get KMS audio to work***
Note: the KMS audio is capable of multi-channel audio i.e. 5.1, 7.1, etc. You will need to look at the volume control applet on the desktop and see what is available to your setup.

For both options, you will need to edit the /boot/config.txt.

If you choose to go with option 2, you will also need to edit the vc4-hdmi.conf file and the pulse audio rules file to get sound from the KMS audio driver to work properly.

Edit as follows w/ proper privileges:

/usr/share/alsa/cards/vc4-hdmi.conf

# Configuration for the VC4-HDMI sound card using software IEC958
# subframe conversion

<confdir:pcm/hdmi.conf>
vc4-hdmi.pcm.hdmi.0 {

	@args.CARD {
		type string
	}
	@args.AES0 {

	@args.AES2 {

				hook_args [
				{
					name "IEC958 Playback Default"
					optional true
					lock true
					preserve true
					value [ $AES0 $AES1 $AES2 $AES3 ]
				}
				]
			}
		}
	}
	status [ $AES0 $AES1 $AES2 $AES3 ]
}

# default with plug
vc4-hdmi.pcm.default {
	@args [ CARD ]
	@args.CARD {
		type string
	}
	type plug
	slave.pcm {
		type softvol
		slave.pcm {
			@func concat
			strings [ "hdmi:" $CARD ]
		}
		control {
			name "PCM Playback Volume"
			card $CARD
		}
	}
}

The PulseAudio rules file needs to be edited as well.

/lib/udev/rules.d/91-pulseaudio-rpi.rules

SUBSYSTEM!="sound*", GOTO="end"
ACTION!="change", GOTO="end"
KERNEL!="card*", GOTO="end"
ENV{SOUND_FORM_FACTOR}!="internal", GOTO="end"

ATTRS{id}=="b1", ENV{PULSE_PROFILE_SET}="rpi-hdmi.conf", GOTO="end"
ATTRS{id}=="b2", ENV{PULSE_PROFILE_SET}="rpi-hdmi.conf", GOTO="end"
ATTRS{id}=="Headphones", ENV{PULSE_PROFILE_SET}="rpi-analog.conf", GOTO="end"

LABEL="end"

Reboot after all changes have been made and enjoy!

@bluestang said in Low framerate on main EmulationStation menu - Pi 4:

v3d_freq_min=500

When I changed V3d_freq to 700, and monitored it using bcmstat.sh while running games, it would not go over 500. When I set gpu_freq to 700, it goes to 700. I realise this goes against the pi4 documentation, but those are my results.

Earlier I added

dtoverlay=vc4-kms-v3d-pi4,noaudio
dtparam=audio=on

Tried also without -pi4 (docs say to add -pi4)
And HDMI was no longer recognizing the Pi...

I get:
Rom flash, Rainbow screen, First stream of kernel loading, then no signal.

If I change back to fkms it returns.

Also weirdly I have to unplug hdmi and reboot to be able to get back in via SSH.

Oh and Happy New Year!

[bluestang]

@paddydukes

What about just using vcgencmd measure_clock v3d?

the core freq will stay at 500, what you want to see is v3d at the overclocked setting instead.

As for the HDMI issue...can you post your whole /boot/config.txt?

And Happy New Year to you too!

Yeah actually at the time I think I was using vcgencmd. I will do this again just to be sure now and post results. It surprised me to say the least.

Ok with gpu_freq (running pcsx-rearmed)

What the hell man... I swear it was capping me at 500 before...

On the boot config, thanks for pushing me to look into it. I didn't realise it was being set below. :D It booted! I am a dummy.

However, now all audio is broken. Redream goes crazy like it's stuck in turbo mode (i think this is as a result of loss of audio sync). LR cores are fine but no audio.

Man, I love this shit. Feel like I am 12 messing around with my first PC.

I assume you didn’t disable the PulseAudio updates and are using HDMI to output audio? If you go to Audio Settings in EmulationStation you should be able to select HDMI from the menu. There is also a Pulse Audio option too, which can be enabled as well.

The desktop audio applet is new too and should have 2 options as well, make sure the right output is selected.

If all that still doesn’t produce audio please post a dmesg log and the contents of /boot/cmdline.txt as well.

Side Note - what audio driver are you using for RetroArch?

[paddydukes]

@bluestang Don't believe I disabled pulse audio, but I haven't heard of it before this!

When I go to audio settings it doesn't let me turn up the volume mixer there (which is set to 0), even set to HDMI. I didn't see a Pulse Audio option though.

Reverting boot config didn't bring audio back.
I'm not running desktop just straight into emulationstation.

Retroarch driver will be whatever the default is, haven't changed it.

Which looks like there's some corruption... how that would happen from the change I don't know...

@paddydukes At this stage I might just clean image and see if it resolves...

KMS requires that you run the latest test kernel which is 5.10.3 as of today.

You are still using 5.4, which has issues. You need to run rpi-update and then proceed with the KMS driver.

Starting with a fresh image may be your last resort. It’s hard to pinpoint issues with too many unknowns especially when you are doing testing.

[paddydukes]

@bluestang Weird that it's still broken when reverting though? I'll update and see anyhow!

And for anyone wondering, yes sadly it appears amiberry is broken due to dispmanx requirement.

KMS disables DISPLAYMANX so any emulator that uses this for the RPi4 will no longer work with KMS.

The RPi4 will eventually transition to KMS as the preferred choice once the driver is ready.

Re: Amiberry there is an option to build it with the SDL2 backend...have you tried that version?

[paddydukes]

@bluestang I just read that and found this. https://github.com/midwan/amiberry/issues/463

Once i get things back up and running I can go down that route!

[paddydukes]

@bluestang Fresh imaged and set everything up again. Backing up my image now :p

Will then rpi-update and attempt to set kms!
