Hi Heiko,

Thanks for the patch.

BR2_PACKAGE_XLIB_LIBXSHMFENCE is selected by BR2_PACKAGE_MESA3D_DRIVER
only if BR2_PACKAGE_XORG7 is also selected. See:
https://gitlab.com/buildroot.org/buildroot/-/blob/2025.05/package/mesa3d/Config.in#L72

In that case, why this dependency is not:

     depends on BR2_TOOLCHAIN_HAS_SYNC_4 || !BR2_PACKAGE_XORG7 # 
libxshmfence

like most of the other drivers?

Could you update this dependency or add an explanation please?

I just copied the config entry from the  "Vulkan broadcom driver" above my
entry. And in this the dependency is just for "BR2_TOOLCHAIN_HAS_SYNC_4".

For sure I will update that.
