Finally, hash links can be freed when the hash context is no longer
relevant. The context is created automatically when needed, and the
owner can delete the context when its done with the relevant hash
tables.
Render passes and subpasses are now mostly initialized, just command
buffers and frame buffer related info to go (including view/scissor for
pipelines).
Not only does this quieten the validation layers, it ensures that all
the object handles are named and where they need to be. Also fixes only
one pipeline being created instead of the 15 or so.
The render passes seem to be created successfully, but pipelines fail
due to not having layout set, resulting in a segfault (bug in validation
layers?).
I don't remember why I kept the abbreviated configs for images and image
views, but it because such that I need to be able to specify them
completely. In addition, image views support external images.
The rest was just cleaning up after the changes to qfv_resobj_t.
.dictionary can ask for standard parsing via a .parse key (value is
ignored currently).
Fields can use $auto to use standard parsing for that field.
If either is used, the plist field descriptors are written.
They're currently just stubs, but this gets the render info loading
working without any errors. The next step is to connect up pipelines and
create the image resources, then implementing the task functions will
have meaning.
This gets an empty (no tasks or pipelines connected) render context
initialized and available for other subsystems to register their task
functions. Nothing is using it yet, but the test parse of rp_main_def
fails gracefully (needs those tasks).
This just sets up the memory block and cexpr descriptors for the
parameters, parameter parsing is separate (and next). The parameters are
aligned to their size.
A bunch of missed struct members, incorrect parse types, and some logic
errors in the parse setup. Still not working due to problems with
vectors from plist string references and some other errors, but getting
there.
There's still a lot of work to do, but the basics are in. The spec will
be parsed into info structs that can then be further processed to
generate all the actual structs, generally making things a little less
timing dependent (eg, image view info refers to its image by name).
The new render pass and subpass structs have their names mangled for now
until I can switch over to the new system.
While the old system did get things going, it felt clunky to set up,
especially when it came to variations on render passes (eg, flat vs
cube-mapped). Also, much of it felt inside-out, especially the
separation of pipelines and render passes: having to specify the render
pass and subpass in the pipeline spec made the spec feel overly coupled
to the render pass setup. While this is the case in Vulkan, it is not
reflected properly in the pipeline spec. The new system will adjust the
render pass and subpass parameters of the pipeline spec as needed,
making the pipeline specs more reusable, and hopefully less error prone
as the pipelines are directly referenced by the subpasses that use them.
In addition, subpass dependencies should be much easier to set up as
only the dependent subpass specifies the dependency and the subpass
source dependency is mentioned by name. Frame buffer attachments also
get a similar treatment.
The new spec "format" isn't quite finalized (needs to meet the enemy
known as parsing) but it feels like a good starting place.
There are some missing parts from this commit as these are the fairly
clean changes. Missing is building a separate set of pipelines for the
new render pass (might be able to get away from that), OIT heads texture
is flat rather than an array, view matrices aren't set up, and the
fisheye renderer isn't hooked up to the output pass (code exists but is
messy). However, with the missing parts included, testing shows things
mostly working: the cube map is rendered correctly even though it's not
displayed correctly (incorrect view). This has definitely proven to be a
good test for Vulkan's multiview feature (very nice).
I ran into the need to get at the label of labeled array element and the
best way seemed to be by setting the name field of the plfield_t item
passed to the parser function, and then found that PL_ParseSymtab
already does this. I then decided passing the array index would also be
good, and the offset field made sense.
Canvas_SortComponentPool now takes the raw canvas component id as it is
specialized to the canvas subpools.
Canvas_SetLen resizes the root view and then updates the hierarchy for
every canvas in the system.
Canvas_InitSys sets up the component system with the systems it needs
(canvas, view, text). This is required to ensure view_href is just past
the canvas components as it is needed for retrieving the actual canvas
component (and thus sub-pool range ids) from arbitrary views in the
canvas.
Entities are fetched with the correct offset from the pool entities.
This will make it easy for client code to set up data needed by the
console before the console initializes. It already separates console
cvar setup and initialization, which has generally been a good thing.
This is a bit of a hack to allow me to work on vulkan's screen update
"pipeline" without having to mess with the other renderers, since it
turns out they're (currently) fundamentally incompatible.
The pic is scaled to fill the specified rect (then clipped to the
screen (effectively)). Done just for the console background for now, but
it will be used for slice-pics as well.
Not implemented for vulkan yet as I'm still thinking about the
descriptor management needed for the instanced rendering.
Making the conback rendering conditional gave an approximately 3% speed
boost to glsl with the GL stub (~12200fps to ~12550fps), for either
conback render method.
The wording might seem a little odd, but cl_screen is really the full 2D
client HUD while the console is completely independent of the client and
shouldn't know that the client even exists. Ideally, the resize events
would be handled by the canvas system, to which end this is a small
step.
