Dependencies on vkparse.hinc were spreading through the code which I
didn't want as that removes a lot of the automation from the automake
files. This keeps all parser code internal to vkparse.c's scope, and any
accesses required for enum and struct (not yet) definitions can be
fetched by name.
Array and single type overrides now allow the parsing of the items
themselves to be customized. This makes it easy to handle arrays and
pointers to single items while also using custom specifications, rather
than relying entirely on the custom override.
QC's int type is named "integer" (didn't feel like changing that right
now), so special case it to be "int".
Output the parse func name (instead of "fix me").
Output a parse func for enums (needed for arrays of enums
(VkDynamicState)).
The static variable meant that Fog_GetColor was not thread-safe (though
multiple calls in the one thread look to be ok for now). However, this
change takes it one step closer to being more generally usable.
Patch found in an old stash.
I had missed the array declaration and thus initialized the pointer to
the offset array incorrectly. Didn't show up until I tried using
multiple offsets.
Shaders can be built as spv files and installed into
$libdir/quakeforge/shaders or as spvc files and compiled into the
engine. Loading supports $builtin/name to access builtin shaders,
$shader/path to access external standard shaders and quake filesystem
access for all other paths.
I had forgotten that msaa samples was governed by the driver (as a max)
and the renderpass setup code simply took the max. Thus why 1 vs 8
caused the display to render incorrectly.
It turned out the msaa setting defaulting to 1 instead of 8 was the
problem no idea why at this stage (need to read up on just how that
setting works). Once I understand just how it works, I'll rework the
msaa handling.
This gets renderpass parsing almost working (not hooked up, though). The
missing bits are support for expressions for flags (namely support for
the | operator) and references (eg $swapchain.format). However, this
shows that the basic concept for the parser is working.
Nothing is actually done yet other than parsing the built-in property
list to property list items (the actual parser is just a skeleton), but
everything compiles
The property list specifies the base structures for which parser code
will be generated (along with any structures and enums upon which those
structures depend). It also defines option specialized parsers for
better control.
It worked as a proof of concept, but as the code itself needs to be a
bit smarter, it would be a lot smarter to break up that code to make it
easier to work on the individual parts.
The tables are generated from the enums pulled out of the vulkan headers
using a ruamoko program (thanks to its reflection capabilities). They
will be used for parsing property lists used to create render passes and
pipelines.
There's still some cleanup to do, but everything seems to be working
nicely: `make -j` works, `make distcheck` passes. There is probably
plenty of bitrot in the package directories (RPM, debian), though.
The vc project files have been removed since those versions are way out
of date and quakeforge is pretty much dependent on gcc now anyway.
Most of the old Makefile.am files are now Makemodule.am. This should
allow for new Makefile.am files that allow local building (to be added
on an as-needed bases). The current remaining Makefile.am files are for
standalone sub-projects.a
The installable bins are currently built in the top-level build
directory. This may change if the clutter gets to be too much.
While this does make a noticeable difference in build times, the main
reason for the switch was to take care of the growing dependency issues:
now it's possible to build tools for code generation (eg, using qfcc and
ruamoko programs for code-gen).
They take a pointer to a free-list used for hashlinks so the hashlink
pools can be per-thread. However, hash tables that are not updated are
always thread-safe, so this affects only updates. progs_t has been set
up such that it is easy for multiple progs within one thread can share
hashlinks.
It turned out I needed access to the physical device from a buffer
object, so rather than storing the vulkan logical device directly in
buffer (and other) objects, store the qfv logical device.
It's just a wrapper around hashtab, but it makes checking if a string is
in a set easy. Way overkill when only a few extensions are enabled, but
more might come later.
This paves the way for clean initialization of the Vulkan renderer, and
very much cleans up the older renderer initialization code as gl and sw
are no longer intertwined.
This fixes the segfault and pushes things very much in the desired
direction of proper system independence for rendering and presentation
separation (though things were headed in the right direction before).
Things are still a mess, but a proper cleanup will be a lot of work and
will, really, involve properly splitting quake-specific code* out from
the rest of the renderer.
* data loading and format specific stuff
A single graphics-capable queue should be enough for now. However, I'm
not sure I'm happy with a lot of the code: it's a bit difficult to write
flexibly configured code for Vulkan (or seems to be at this stage),
especially in C.
After messing with SIMD stuff for a little, I think I now understand why
the industry went with xyzw instead of the mathematical wxyz. Anyway, this
will make for less pain in the future (assuming I got everything).
I'm not certain despair actually meant for the break to be there. It
certainly would have sped up the game a bit but at the expense of proper
blood trails in the software renderers.
These are the ones where I could easily make scan-build happy. They do seem
to be potential holes where invalid data in one place could result in use
of uninitialized values.
