This is a hack to destroy all HostCounter instances before the base
class destructor is called. The query cache should be redesigned to have
a proper ownership model instead of using shared pointers.
For now, destroy the host counter hierarchy from the derived class
destructor.
This reworks how host<->device synchronization works on the Vulkan
backend. Instead of "protecting" resources with a fence and signalling
these as free when the fence is known to be signalled by the host GPU,
use timeline semaphores.
Vulkan timeline semaphores allow use to work on a subset of D3D12
fences. As far as we are concerned, timeline semaphores are a value set
by the host or the device that can be waited by either of them.
Taking advantange of this, we can have a monolithically increasing
atomic value for each submission to the graphics queue. Instead of
protecting resources with a fence, we simply store the current logical
tick (the atomic value stored in CPU memory). When we want to know if a
resource is free, it can be compared to the current GPU tick.
This greatly simplifies resource management code and the free status of
resources should have less false negatives.
To workaround bugs in validation layers, when these are attached there's
a thread waiting for timeline semaphores.
Now all that remains is:
18 instances in file_sys code
14 instances in GDB stub code (this can be tossed wholesale)
4 instances in HLE code
2 instances in settings code.
Previously this function was using ~16KB of stack (16528 bytes), which
was caused by the function arguments being taken by value rather than by
reference.
We can make this significantly lighter on the stack by taking them by
reference.
We make it explicit that we're truncating arithmetic here to resolve
compiler warnings (even if the sizes weren't u32/u64 arithmetic
generally promotes to int :<)
Now that the GPU is initialized when video backends are initialized,
it's no longer needed to query components once the game is running: it
can be done when yuzu is booting.
This allows us to pass components between constructors and in the
process remove all Core::System references in the video backend.
- Some games like Shipped have a minimum requirement of 0 connected players and is undesired behavior. We must require a minimum of 1 player connected regardless of what games may ask.
Now left and right joycons have the same priority (meaning both needs to be supported by the game).
Explanation of the new heuristic:
Assign left joycons to even player indices and right joycons to odd player indices.
We do this since Captain Toad Treasure Tracker expects a left joycon for Player 1 and a right Joycon for Player 2 in 2 Player Assist mode.
