[NEWS] Fedora 40 is officially released!

I have reported that error.

I also pick up few other errors with applications such as dosbox-staging.

The common issue is that apps that are built with vendored Fedoran libs
are likely to misbehave. This is one of many reasons why few packages
have to resolve to use the bundled libs that the app come with.

What was the issue with dosbox-staging? Something I should look at or do you think it's packaging-specific?

I got segfault when trying to run Master of Orion II

Yeah, something was borked with the default DOSbox-Staging on F40. I installed the suggested --advisory=FEDORA-2024-b6cc2aa248` and that mitigated my issues, though I did have DOSBox hard lock once while running Redneck Rampage with a VESA mode enabled afterward. Fortunately the Rednukem source port compiled and ran effortlessly on the hardware. I'll try out other DOS games as free time becomes available... to test the stability, of course.

[ClassicHasClass]

That version should have my fix in it, so it must be something else.

[Hasturtium]

I'm not worried, Redneck Rampage was always flaky and in hours since it hasn't so much as burbled - which means DOSBox-Staging is at least as stable as any actual DOS machine I ever ran.

Incidentally, I did a performance comparison of DOSBox-Staging between my three machines by running Quake in 320x200, and both my M2 Air and Ryzen 5700GE notch over 200 fps, while the Power9 wrangles about 35. I want to be clear that I'm not complaining: the Power9 is delivering performance that feels very much like a midrange Pentium, which means it's sufficient for anything that all but crazy people would ask of MS-DOS, but I am curious about the sheer amount of that difference.

[ClassicHasClass]

I'm not sure, actually. I'll have to load it up on my M1 Air and check it out. The x86_64 figure could be because those don't use dynrec, but ARM should ... unless you're running the Intel Mac build on your M2, not an Apple silicon build?

You're right - I figured the Ryzen was largely running native code. To the point on Apple Silicon, the DOSBox Staging build I snagged indicated it was a Universal Binary for Apple Silicon and Intel, but I  wonder if it it's running an Intel-native binary and doing an end run around dynrec. Let me know what you find on the M1.

[ClassicHasClass]

Is Rosetta checked in Get Info?

[Hasturtium]

It was not. Doing a comparison with Rosetta enabled versus ARM-native yielded this result:

Running timedemo demo1 for DOS Quake v1.07 at 320x200 in DOSBox-Staging:
Rosetta: 80.5 fps
Native: 145.0 fps

I don't know why I thought the Air pulled 200+ fps earlier, but 145 fps is easily high-end Pentium III territory regardless.

[ClassicHasClass]

That gives me some point of comparison, though it may be difficult to figure out what specifically the ARM dynrec is benefiting from. But thanks for looking at it.
