Solved Is this a nvidia-driver version problem, or a vulkan related problem (torzu and emulators/yuzu) ?

[SDK Chan]

Torzu, and emulators/yuzu core dumps.
The lines which particularly made me curious are
[ 1.415597] Render.Vulkan <Info> video_core/vulkan_common/vulkan_device.cpp:GetSuitability:1004: Device doesn't support extension VK_EXT_external_memory_host

The nvidia-driver version, and the nvidia-drm-*-kmod version is the default one specified in x11/nvidia-drivers/Makefile.version.
The nvidia modules loaded are:

Input:
kldstat | grep nvidia

Output:
11    1 0xffffffff82680000    149b0 nvidia-drm.ko
17    2 0xffffffff82800000  40ac9a8 nvidia.ko
18    1 0xffffffff868ad000   1325e8 nvidia-modeset.ko

Could someone with a NVidia GPU eventually try out emulators/yuzu ?
As I believe the core problem lies within the GPU now, rather than my torzu port.
Sudachi-emu shows me the same errors, too.

Terminating due to uncaught exception 0x2d4536896280 of type Xbyak::Error

A very nasty bug, indeed.
I solved the problem with yuzu, and torzu by downgrading FreeBSDs xbyak version to 6.68.
Eventually I am going to need to use the external xbyak version after all...
