FEX 2504 Ships More Optimizations For Running x86_64 Linux Binaries On ARM64

([Free Software] 6 Hours Ago FEX 2504)


FEX 2504 is out with its newest monthly feature update for this open-source emulator that allows running x86/x86_64 binaries on AArch64 Linux hosts. This alternative to QEMU and Box64 continues focusing on new performance optimizations to further enhance the appeal and speedy potential of this x86_64-on-ARM64 emulator.

FEX 2504 brings initial metadata support for Windows PE Volatile Metadata, an audio fix for the game Slay the Spire, and other performance optimizations. Volatile Metadata is a feature of Microsoft MSVC 2019 and leads to the compiler generating "volatile" metadata that can be used by Microsoft's Prism ARM64 emulator to avoid costly emulation of the x86 memory model. FEX is now supporting this and in conjunction with Wine can mean more performance gains.

Some of the FEX performance optimizations over the past month have focused on better optimized SHA256, support for the Arm FEAT_FRINTTS extension, various AVX handling improvements, and a variety of other fixes and targeted performance tweaks.

In a forest a fox bumps into a little rabbit, and says, "Hi,
Junior, what are you up to?"
"I'm writing a dissertation on how rabbits eat foxes," said the
rabbit.
"Come now, friend rabbit, you know that's impossible! No one
will publish such rubbish!"
"Well, follow me and I'll show you."
They both go into the rabbit's dwelling and after a while the
rabbit emerges with a satisfied expression on his face. Comes along a
wolf. "Hello, little buddy, what are we doing these days?"
"I'm writing the 2'nd chapter of my thesis, on how rabbits devour
wolves."
"Are you crazy? Where's your academic honesty?"
"Come with me and I'll show you."
As before, the rabbit comes out with a satisfied look on his face
and a diploma in his paw. Finally, the camera pans into the rabbit's cave
and, as everybody should have guessed by now, we see a mean-looking, huge
lion, sitting, picking his teeth and belching, next to some furry, bloody
remnants of the wolf and the fox.

The moral: It's not the contents of your thesis that are
important -- it's your PhD advisor that really counts.
