Any idea of the latest previous version that worked in this configuration?

[Shatur]

Unfortunately, first time trying it on the phone. I compiled it from source. Maybe you could suggest commits that I can try?

[hrydgard]

Well if you can compile from source, then you can even do a git bisect. Or just manually pick som versions, maybe start 100 revisions back or something? Any idea approximately when you tried it and it worked?

[Shatur]

I just used AUR that basically a recipe to compile the package. The issue that the compilation takes a lot of time on the phone and cross-compilation is not very easy to setup... Maybe you could suggest the commits to try?

@Shatur try v1.14

[Shatur]

@sum2012 tried, same result :(

The timing of "ThreadManager::Init" in that log seems weird.

Anyway, does PPSSPP proper work? RetroArch seems to mostly get in the way, performance is worse with it and there's a lot of bugs that only exist when using it. It would at least help to know if PPSSPP runs fine on this device without the libretro garbage. Do other emulators work?

Is it possible to compile standalone PPSSPP for aarch64? I trying to, but having this error:

Do other emulators work?

Yes, other retroarch cores such as PS1 works. My device have OpenGL ES 3.1 support.

I can confirm the issue with libretro-ppsspp, I tried 1.13.2, 1.14.0, 1.14.4 and 1.15.3 But I compiled ppsspp (git version) and is working great, note that the AUR package needs some minor changes not just the arch

So most likely it's some kind of issue introduced by the retroarch layer

How are you compiling this? It seems like maybe you're trying to compile x64 or something. You should run ./linux_arm64.sh in ffmpeg/.

[Shatur]

I used this PKGBUILD. But looks like @pinoverclock already compiled it and confirmed that the issue is in libretro backend.

[pinoverclock]

Original AUR package: ppsspp-git Modified PKGBUILD: ppsspp_PKGBUILD_mod Custom configuration file for ffmpeg (needs to be included in the same folder as the PKGBUILD): linux_arm64_ppp.sh Note that (sadly) clang won't like any exotic mtune/mfix cflags

After some testing/tweaking still heavy games get low fps (10/30), but more than I was expecting from this device anyway, other than that it runs as was expected.

@pinoverclock I have the following error with your PKGBUILD at the end:

CMake Error at ext/rcheevos-build/CMakeLists.txt:44 (add_library):

Happens after compilation on install step. Have you encountered such a problem?

[pinoverclock]

I see in the last PKGBUILD the author has included a new repo sync https://github.com/RetroAchievements/rcheevos.git I haven't tried it myself yet but I would try to include the ppp changes in that last PKGBUILD

wget -qO PKGBUILD https://aur.archlinux.org/cgit/aur.git/plain/PKGBUILD?h=ppsspp-git wget -qO linux_arm64_ppp.sh https://pastebin.com/raw/nTz96K9g wget -qO ppsspp-ppp-pkgbuild.patch https://pastebin.com/raw/61E2TCMa patch PKGBUILD < ppsspp-ppp-pkgbuild.patch

[Shatur]

@pinoverclock thank you a lot. I probably should open an issue in https://github.com/hrydgard/ppsspp-ffmpeg to request include scripts to build on Arm64 to simplify this process. If I understand correctly, current linux_arm64.sh is for cross-compilation, right?

[pinoverclock]

I think so, linux_arm64.sh is just used to specify the compiler arch, flags and options so you can customize it for your device

[gouchi]

@Shatur Is it is still an issue ? Thank you.

[Shatur]

Can't confirm, no longer run PPSSPP on PPP.

[gouchi]

@Shatur Thank you for your feedback.

@pinoverclock Is it is still an issue ? Thank you.
