I think the entry for ntivesdk is correct ?

[oe-core][PATCHv2] default-providers.inc: add entries for virtual/libsdl2

[Markus Volk]

virtual/libsdl2 can be provided by 'libsdl2' and 'libsdl2-compat' where the latter
is a replacement for libsdl2 that uses libsdl3 behind the scenes and should
be favored if applicable.

Re: [oe-core][PATCHv2] default-providers.inc: add entries for virtual/libsdl2

[Alexander Kanavin]

This is fine, but it makes me wonder: is libsdl2-compat compatible
enough to build qemu-system-native with it? Can you try that? Then we
might consider switching over to sdl3 in core.

I have already tried this. I have set it up as follows:
VIRTUAL-RUNTIME_libsdl2 = ā€œlibsdl2-compatā€
PREFERRED_PROVIDER_virtual/libsdl2 = ā€œlibsdl2-compatā€
PREFERRED_PROVIDER_virtual/libsdl2-native = ā€œlibsdl2-compat-nativeā€
PREFERRED_PROVIDER_virtual/nativesdk-libsdl2 = 
ā€œnativesdk-libsdl2-compatā€

and I was able to build my complete image, which includes building 
qemu-system-native
and also a lot of libsdl2 games, and at least compilation-wise there 
were no problems.
I also noticed quite some runtime improvements if running libsdl2 apps 
under wayland

Some possible problems I can think of:

- libsdl2-compat would add a requirement for x11 and opengl
- I'm not sure why this is, but libsdl2-compat was added to 
non-repro-meta-oe.inc, which
  suggests there may still be a reproducibility issue

This is already the case for libsdl2-native, so it won't worsen
things. At some point we can see if we can disable x11 and run
qemu-system-native as a pure wayland client, perhaps only after they
add direct sdl3 support.

Yes, this needs to be addressed before adding to core.
