This is necessary for the fexserver to function correctly when chrooting
in to our rootfs and doing things.
Requires independent rootfs script modifications which will come with
the next rootfs update.
Problem comes down to a chroot supporting multiple users, where our
typical use case is only one user. Bind the server file to a single
server for the entire chroot session regardless of users, solving this
problem inside the chroot.
Fixes apt-get inside of chroot, which runs as user _apt.
Some of these functions are missing that games rely on.
Only glGetVkProcAddrNV will cause us pain, so avoid it for now.
The rest are simple and at least glXWaitX fixes some games.
Fixes#1893Fixes#1893
Multiple games will query symbols that are leaked but we don't support.
It is safe to return nullptr in these cases.
Print a warning message still just in-case someone fails hard at GL.
This changes how host trampolines for guest functions are created. Instead
of doing this purely on the guest-side, it's either the host-side that
creates them in a single step *or* a cooperative two-step initialization
process must be used. In the latter, trampolines are allocated and partially
initialized on the guest and must be finalized on the host before use.
Depending on the operation we will do a vector insert or removal while
iterating over the vector.
Fixes a use after free that asan found when insert caused the vector to
resize.
This will help compiling on older distros which are shipping older
Vulkan-Headers.
We need to catch newer Vulkan features earlier than what distros ship
since it is highly common that users will update their drivers through
means that make their drivers be newer.
For example to build on Ubuntu 20.04 we will support symbols much newer
than what that verison of the distro supports.
We could wrap all uses of newer features behind `#ifdef` checks, or
include the newest version of the loader that FEX itself supports.
The submodule is much cleaner and resolves the issue of drivers
supporting newer vulkan versions than libvulkan-dev.
Again super common with Nvidia blob users, kisak-ppa users, or people
updating mesa directly to be on the bleeding edge.
