Ideally Common.h wouldn't be a header in the Common library, and instead be renamed to something else, like PlatformCompatibility.h or something, but even then, there's still some things in the header that don't really fall under that label
This moves the version strings out to their own version header that doesn't dump a bunch of other unrelated things into scope, like what Common.h was doing.
This also places them into the Common namespace, as opposed to letting them sit in the global namespace.
SetFormat() is only ever used internally. ResetBuffer() is only
used to implement the VertexManagerBase class interface, so
there's no need to make it protected.
The "X.h" header *just* contains protocol constants, not functions or
typedefs - so stuff like "Display" and "Window" are not defined unless
you include "Xlib.h".
"Xrandr.h" happens to include "Xlib.h" itself, so enabling xrandr
effectively worked around this issue.
If we allocate a large amount of memory (A), commit a smaller amount,
then allocate memory smaller than allocation A, we will have already
waited for these fences in A, but not used the space. In this case,
don't set m_free_iterator to a position before that which we know is
safe to use, which would result in waiting on the same fence(s) next
time.
Calling vkCmdClearAttachments with a partial rect, or specifying a
render area in a render pass with the load op set to clear can cause the
GPU to lock up, or raise a bounds violation. This only occurs on MSAA
framebuffers, and it seems when there are multiple clears in a single
command buffer. Worked around by back to the slow path (drawing quads)
when MSAA is enabled.
Before this change, we simply fail if the device does not expose one
queue family that supports both graphics and present. Currently this is
fine, since devices tend to lay out their queues in this way. NV, for
instance, tends to have one queue family for all graphics operations and
one more for transfer only. However, it's not a hard requirement, and it
is cheap to use a separate queue, so we might as well.
Currently, this is only the logic op bit, but this will be extended to
the framebuffer fetch/blend modes. In the future, when/if we move to
VideoCommon pipelines, this state will be part of the pipeline UID
anyway, and we can mask it out in the backend by using a two-level map,
so the shaders/programs are shared.
Based on hardware tests, masking occurs for the accelerator registers.
This fixes Red Steel and Far Cry Vengeance, which rely on this behavior
when reading back the current playback position from the DSP.
