I don't remember why I thought it was a good idea to respect embedded
nul characters, but doing so makes appendstr O(N) instead of O(1) (or
O(N^2) instead of O(N) for multiple appends of n chars (N = sum(n)).
Also, this makes appendstr consistent with dasprintf.
I've decided that I want reserve to mean only allocate backing memory,
not modify the size of the string, but I didn't want to rework much code
in the process. I might eventually get right of the open functions, but
I wouldn't be surprised if that's another decade or two in the future.
I'm surprised other types weren't affected, but vec4's ecoding was being
picked up for float. Thankfully, all that was needed was checking width
and columns.
Builtins calling other functions that call back into progs can get their
parameter pointers messed up resulting in all sorts of errors. Thus wrap
all callbacks to progs in PR_SaveParams/PR_RestoreParams.
Also, ditch PR_RESET_PARAMS in favor of using PR_SetupParams and move
setting pr_argc into PR_SetupParams.
Thanks to validation layers showing command buffer debug regions, it was
pretty easy to find the offending buffers. Did need to modify
QFV_PacketCopyBuffer to take a source barrier as well as the destination
barrier, but this is probably for the best.
Now all pipelines and any tasks that have a command buffer attached get
a region using their names (tasks use the function name). I don't know
when it happened, or if I failed to notice last time, but (sync)
validation layers now include the debug region for command buffers: very
nice.
And point the return pointer at the return buffer. And, of course,
restore it. This fixes a really subtle (ie, difficult to find) bug
caused by the recent optimization improvements in qfcc: the optimizer
had decided to set the return value of a message call to the parameter
for the next call, but because the message was to the receiver class for
the first time, the class's +initialize was called. The +initialize
method returned self, which of course when into the parameter for the
*next* call, but the first call hadn't been made, so its parameter got
corrupted.
The particle renderer uses the palette texture in the vertex shader, so
updating the palette needs the vertex shader stage included in the
barrier, but I imagine not all texture updates will need it, so add a
parameter to Vulkan_UpdateTex to select inclusion.
Recent nvidia drivers now crash with more than 17 views when building
pipelines. Still no idea if it's me or the drivers. However, I really
need to come up with a way to use the render graph render passes as a
template so things aren't so hard-coded.
It's disabled by default because it's a runtime thing and I'm not sure I
want to keep it enabled, but it did find some issues (which I've cleaned
up), although it didn't find the problem I was looking for :P
Handle type encodings aren't actually compatible with basic type
encodings as their width is always one and thus the tag field collides
with the basic type encoding's width field.
evdev can send multiple event packets for a single "event", but QF was
reading them one per frame, thus the feeling of buffered input at lower
frame rates (because they were buffered in the kernel). This also takes
care of most of the jerky motion with my 3d mouse, though there is still
a weird snap every second or so when rotating and translating at the
same time.
There's still a lot of work needed to separate out quake from
quakeforge, but this lets my test scene get a rather mangled scene
rendering (weird translucency: not sure what I've done wrong: probably
bad clear).
It turns out what I thought was a cascade selection bug was just very
bad choice of cascade steps: factors of 8 just don't work nicely. I'm
not sure that simple factors work all that well, either. I need to make
the cascade system configurable and probably support more cascades.
This puts pixels that have not been rendered at infinity. I was rather
surprised to see fog in my test scene, but it depended on my position
relative to the origin, so something was definitely off (the pixels were
at the origin).
I'm not sure why the final range was only a factor of 4 instead of 8.
There are still issues with range selection, but I'll look into them in
a bit (flying around my little test scene really shows the problems).
IN_UpdateAxis (for nice handling of axis updates, especially relative
motion for mice) and IN_Binding_HandleEvent because registering an event
handler blocks qwaq's internall call to IN_Binding_HandleEvent.
With this, it is a little easier to make qwaq independent of quake. The
default dirconf is still meant for quake, and fs_dirconf can still be
used to override the configuration.
While every possible subsystem needs an initialization call, all that
does is add the actual initialization task to the render graph system.
This allows the render graph to be fully configurable, initializing only
those subsystems that the graph needs.
Scripted initialization is still separated from startup as render graph
creation needs various resources (eg, attachments) defined before
creating render and compute passes, but all those need to be created
before the subsystems can actually start up.
Finally. However, it has effect only when no render config is provided.
When a config is provided, things will break currently as nothing is
done yet, but getting a config in will take some work in qwaq and also
the render graph system as I want to make the startup functions
configurable.
