Kernel 4.x

Hi, Good job. Do you plan to switch to most recent Kernel for XU4? Someone has talk about it to RC here https://forum.odroid.com/viewtopic.php?f=91&t...

nadenislamarre

thanks for your feedback.

1) "no background music" is "- es sound menu " is think
2) can you explain "bug with usb sticks" : i don't understand this one. i've no problem for this one. can you reproduce and create a support file so i can check ? the kernel includes 4.14.5 which includes some recent fixes for usb3, which may be related to that. @justin any idea about this one ?
3) i will try psp tonight and fix if needed.
4) i didn't try fba too. i will.
5) i got no bug with psx. can you take a picture (photo) ? which game ? all ?
6) amiga is not yet supported on xu4, its only rpi/x86 for the moment. i've not finnished this work.

the bug of the controller is certainly related to retroarch, I have no pb with the n64 and the dreamcast. when I want to access the retroarch menu with hotkey, I have to reconnect the controller and it goes too quickly in the menus. for psx, this is colin mcrae 2, at the beginning of the game, the view is reversed and unplayable. it worked on all older versions, the other games seem to work. I can send you the report file of the information system menu by email.
thank you for your work

nadenislamarre

with the new details, i will try to reproduce. thanks.
i understant that it's just the retroarch menu that is causing the issue.
for colin, i tried an older version; can you confirm the bug doesn't exist with the current xu4 batocera version ?

michel83

the bug with colin exists only with this version. if the joy is disconnect, the car is visible, and invisible if it's connect. When I press the hotkey button, a message appears "shaders: / ..." at the bottom of the screen. if I open and close the menu retroarch, I have to reconnect the joystick to replay the game every time.

I just tested with a wireless controller and I no longer have the pb with colin on psx. But there are some pb with the controller. the buttons work very badly, i have to start several times to access the retroarch menu and sometimes its going too fast to navigate in the menu. also, i had some freeze when playing.

Thank for this Amazon work.
So far here are the very small concerns :
- change To French the reboot request by batocera not working
- kodi is not launching

Will make some additional try tomorrow

nadenislamarre

french works for me.
kodi is not yet done.

nadenislamarre

hum retroarch menu working for me
it is only for colin that the menu doesn't work ?

yaazzz

Sorry for bad explanation : french is working. The issue is just the reboot : problem seen only after langage selection.

michel83

no, when i use the wireless controller, colin works and fba doesnt have hatched sound

nadenislamarre

hum, i don't have fba working at all. have you done something or it's just my games ?
ppsspp doesn't support kms, so, it looks compromized for the moment for it ;-(

updated todo list :
- kodi
- reicast sound
- es sound menu : probably broken not only on xu4
- psp not working
- fba ?

nadenislamarre

for the french, i get a reboot prompt. i don't reproduce, it works normally for me.

michel83

for me too , it works in french. in fba libretto i have tested outrun,metalslug (neogeo) and a few other games. i have tested also a few games in reicast, i didnt notice an sound pb

nadenislamarre

psp finally works.

updated issue list (all related to the sound) :
- kodi : memeka patches
- reicast sound : crappy sound (pulseaudio may solve)
- psp : crappy sound / performances
- es sound menu : no sound

MastaG

Perhaps ask meveric about reicast.
He has it working well in his OGST image 🙂

memeka

I have it working well as well with pulse. And meveric if is also using pulse on ogst. I think it's possible to have it working on alsa too with a custom asound.conf but I don't know the settings...

memeka

I will also push kodi (17.6) Monday together with ffmpeg. I removed all of owersun's code and only have wayland, drm, and ffmpeg patches (wayland not necessary for batocera, but I'm releasing an image on wayland with it 😃)

What GCC version are you using? I've had better results with GCC 7.0 as far as any little issues in compiling being found. It also tells me where code issues may be involved. Also, have you had any luck compiling with uclibc instead of glibc? If it works, you may find less bloated code as it's designed for systems like the RPi and the like. Glibc is mainly for PCs and works which require specialized non-standard instructions beyond what the standard C library offers. I noticed you were using glibc by default.
Let me toss something together and see what happens.

d3m0n1q_733rz

Alright, so I've discovered that the uClibC code is extremely outdated and still depends on a depreciated (and no longer supported) instruction swpb that should be changed to strexb instead and won't compile correctly. On top of that, there's a local file for Norwegian that was incorrectly named no_NO instead of nb_NO that also causes issues. The entire Buildroot toolchain needs updated to a more current version.
Also, I've gone ahead and set the settings for the processor to Cortex-A53 for the RPi3 instead of the old A7 or whatever you had selected. I'm still testing it, but it allows the more up-to-date float-point instructions to be used along with NEON which should automatically vectorize what it can and speed-up any floating point calculations based on single or double precision (which hardware performs the float operation).
Okay, since that's out of the way, I also enabled the enhanced RPi3 firmware for more GPU capabilities, enabled the TFT support in case someone wants to use the TFT to make a hand-held system, and some of the wifi and bt modules that were made for the RPi3. I'm also trying to switch to busybox if possible as the loader since it's not as heavy on resources as bash is.

I'm sure there's a reason for the way you did things here, I'm just wanting to see if there's a better way that can produce faster code that will run the emulators at full speed on the RPi3 by taking full advantage of the hardware instead of partial. Here's hoping I stumble upon something good.

i put pulseaudio, but i probably didn't do correctly while it makes reicast crash.
reicast and ppsspp and exactly the same sound options, strange, so i'm still not sure where the but is (reicast/ppsspp or system configuration).
When i change the sample rate from 44100 to 24000 for example in reciast, the bad sound disappear, but of course the fps and game become slow because it's based on the sound. i think that reicast doesn't play (alsa plugin) at the correct sample rate in my case.

glibc is used (not uclibc)
gcc 5.x is used. i will make a try in 7.x. but can you confirm it's for performances issues ?
changing gcc is not always easy while often, some programs doesn't support it (i build all the distro with the same gcc) and i've to fix it.

i'm still looking for the solution for the sound.
@michel83 did you test reicast or ppsspp for the sound ? for reicast, just the dreamcast aniamtion at boot is crappy.
