Skyline crashes on ARM macOS with Hypervisor or Host memory mode

See original GitHub issue

Description of Issue

The Skyline modding framework crashes on ARM macOS when either the Hypervisor or any Memory Manager mode other than Software is used.

Reproduction Steps

Download the latest Skyline beta from https://github.com/skyline-dev/skyline/releases/tag/beta
Right-click Super Smash Bros. Ultimate in the game list and select Open Atmosphere Mods Directory
Copy the exefs folder in the downloaded .zip to this directory
Start the game with the Hypervisor or any Memory Manager mode other than Software

Note that this crash is triggered by the Skyline mod loader itself even with if no other mods like Arcropolis are loaded.

I’ve experimented with host mapped mode a bit, seems like forcing Skyline use a 16 KB-aligned destination address in the svcMapProcessMemory call doesn’t help either. I guess this doesn’t necessarily mean that the physical address on the host has the correct alignment as well? It’s possible that I did something wrong though, I’m not really familiar with this part of the Skyline code base.

The emulator physical memory allocation is also not 16 KB aligned. We should probably enforce physical memory allocations to be 16 KB aligned when using host mapped mode on platforms with 16 KB pages.

Is this also the case in Ryujinx?

Not on the hypervisor. On the JIT it always invalidates the unmapped memory ranges on the JIT cache. There’s a InvalidateCacheRange method on the CpuContext, but it’s currently unused, and it does nothing on the hypervisor https://github.com/Ryujinx/Ryujinx/blob/master/Ryujinx.Cpu/AppleHv/HvCpuContext.cs#L34
