`[32bit loc | 32bit attributes]`
Use `std::map::lower_bound(loc << 32)` to find the first address that matches the key in O(logn) time, finer grained searchs can happen after the fact in O(n) time.
Fixes render-texture cache lookups
Uses the graphics pipeline to both blit and transpose the 3ds-formatted
textures. Does not read from the actual texture just yet since we dont
write to the descriptor just yet. Some other patterns need to line up
before then.
A utility class from a personal project for managing a heap of
descriptors of a particular layout.
Allows the display graphics pipeline to be successfully created,
satisfying its descriptor layout issues.
Now there is just one primary command buffer where all work is enqueued
into. At the end of the frame, the next frame's CPU-side fence is waited
on before resetting and beginning its command buffer again for
recording. This command buffer must always be in the RECORDING state.
Rather than allocating new command buffers for each small task, schedule
all work onto the frame's main command buffer to be dispatched at
display-time. Fixes all layout transition and synchronization issues.
Technically we can generate every possible render-pass up-front based on
the possible combinations of ColorFmt and DepthFmt, but we should only
allocate what the game asks for. Save that pattern for pipelines.
This surface is managed by SDL itself, so there is no need to keep it in
a Unique handle for us to delete. Fixes the bug where vulkan crashes
during shutdown.
Instead of operating directly on the swapchain images, we have our own
top/bottom framebuffer images that will be rendered to independent of
having an available swapchain. The images are blitted into the swapchain
images, allowing for resizing too!
Lots of todos, this should probably just be its own self-contained
object to allow the emulator to render "headlessly" regardless of a
swapchain existing or not.
This value is needed for vulkan to properly allocate a surface, and would benefit OpenGL to move more of its initialization code into here rather than in `emulator.cpp`.
Headlessly creates a new vulkan instance, with conditional MacOS
support, and enables the `VK_EXT_debug_utils` instance-extension with a
debug-messenger to hook onto validation layer messages.
A lot of the architecture of the emulator here does not allow for vulkan
to initialize easily since it involves a bit of data to be exchanged
between SDL and Vulkan. This commit just adds the foundational linkage
and library code for vulkan support.
