b9bc3fa132 [vulkan] Split out the push constants helper
It proved to work well in the sprite pipeline, and should be useful for
cleaning up the magic numbers in bsp and alias.

0b99ff104d [vulkan] Clear the color attachments
This means color, emission, and translucent. Fixes the HOM issues on my
VersaPro (but halves the frame-rate... definitely need to bring back the

db6c76d583 [vulkan] Abandon bindless rendering
At least for now, it is more trouble than it is worth as it (or my
implementation of it) breaks lavapipe and renderdoc.

8228146ac0 [vulkan] Use the particle system buffer for indirect draws
I realized I'd need to get the particle counts out to the draw commands

6aaf5c3722 [vulkan] Start work on particles for Vulkan
This gets the pipelines loaded (and unloaded on shutdown). Probably the
easy part :P. Still need to sort out the command buffers,
synchronization, and particle generation (and probably a bunch else
that's not coming to mind).

c366b1b7bb [vulkan] Implement the sprite render passes
It turned out the bindless approach wouldn't work too well for my design
of the sprite objects, but I don't think that's a big issue at this
stage (and it seems bindless is causing problems for brush/alias
rendering via renderdoc and on my versa pro). However, I have figured
out how to make effective use of descriptor sets (finally :P).

The actual normal still needs checking, but the sprites are currently
unlit so not an issue at this stage.

743a732bd7 [vulkan] Correct the semantics of QFV_NextOffset
I'm not at all sure what I was thinking when I designed it, but I
certainly designed it wrong (to the point of being fairly useless). It
turns out memory requirements are already aligned in size (so just
multiplying is fine), and what I really wanted was to get the next
offset aligned to the given requirements.

36e0d857a2 [vulkan] Create the non-C side of the sprite pipeline
This adds the shaders and the pipeline specs. I'm not sure that the
deferred rendering side of the render pass is appropriate, but I thought
I'd give it a go, since quake sprites are really cutoff rather than
translucent.

2db8d11dd0 [vulkan] Clean up some excessive descriptor sets
With the switch to multi-layer textures for brush models, the bsp and
alias texture descriptor sets became identical and thus the definitions
shareable. However, due to complications I don't want to address yet,
they're still separately identified, but I should be able to use the
texture set for most, if not all, pipelines.

0eb556b8f9 [vulkan] Load sprite model data
The vertices and frame images are loaded into the one memory object,
with the vertices first followed by the images.

The vertices are 2D xy+uv sets meant to be applied to the model
transform frame, and are pre-computed for the sprite size (this part
does support sprites with varying frame image sizes).

The frame images are loaded into one image with each frame on its own
layer. This will cause some problems if any sprites with varying frame
image sizes are found, but the three sprites in quake are all uniform
size.

c5cfcc7bfd [sprite] Separate model and texture loading
As much as it can be since the texture data is interleaved with the
model data in the files (I guess not that bad a design for 25 years ago
with the tight memory constraints), but this paves the way for
supporting sprites in Vulkan.

eee25d21ba [zone] Clean out unnecessary memsets
As the cache blocks are always filled in with a memcpy, there's no need

ff40563fc0 [zone] Squeeze cache_system_t to fit into 64 bytes
The cache system pointers are now indices into an array of
cache_system_t blocks, allowing them to be 32 bits instead of 64, thus
allowing cache_system_t to fit into a single CPU cache line. This still
gives and effective 38 bits (256GB) of addressing for cache/hunk. This
does mean that the cache functions cannot work with more than 256GB, but
should that become a problem, cache and working hunking hunk can be
separate, and it should be possible to have multiple cache systems.

fde47d6983 [quakefs] Clean out some excess memsets
There's no point in zeroing out memory that is only going to be
overwritten by the loaded file (excess bytes beyond the end of a
massaged text file shouldn't be accessed anyway, and the terminating
null is still written).

2086125e0b [quakefs] Take in the pointer to the global hunk
This is needed for cleaning up excess memsets when loading files because
Hunk_RawAllocName has nonnull on its hunk pointer (as the rest of the
hunk functions really should, but not just yet).

Bill Currie
39c020908c [zone] Return the pointer to the global hunk
In trying to reduce unnecessary memsets when loading files, I found that
Hunk_RawAllocName already had nonnull on it, so quakefs needed to know
the hunk it was to use. It seemed much better to to go this way (first
step in what is likely to be a lengthy process) than backtracking a
little and removing the nonnull attribute.

8c5c39cbe4 [vulkan] Mix turb full-brights into main color
I'd forgotten (when doing the original brush texture loader) that
turbulent surfaces were unlit and thus always full-bright, then never
wrote the turb shader to take care of it. The best solution seems to be
to just mix the two colors in the shader as it will allow turb surfaces
to be lit in the future (probably with severely limited light counts due
to being a forward renderer).

11492d77ce [vulkan] Switch bsp renderer to multi-texture

look good).

d7f588ecfe [vulkan] Rework bsp texture loader
BSP textures are now two-layered with the albedo and emission in the two
layers rather than two separate images. While this does increase memory
usage for the textures themselves (most do not have fullbright pixels),
it cuts down on image and image view handles (and shader resources).

ff6d6f6dd6 [vulkan] Rework shaders and pipelines for bindless textures
Smashing everything in the process :P (need to work on the C side).
However, while bindless is supposedly good for performance, the biggest
gain this will bring is portability: the texture counts are
automatically limited to what the hardware can handle, and the reliance
on push descriptors is removed (though they were nice and did help get
things up and running).

d2eb928210 [cexpr] Add a small library with some useful functions

44102f2639 [cexpr] Support chained contexts for scoping
cexpr's symbol tables currently aren't readily extended, and dynamic

when a symbol is not found in the current context's symtab, but minor
efforts are made to avoid checking the same symtab twice (usually cased
by cloning a context but not updating the symtab).

8271860fb3 [vkgen] Add support for fixed arrays
I want to support reading VkPhysicalDeviceLimits but it has some arrays.
While I don't need to parse them (VkPhysicalDeviceLimits should be

84a24dbb34 [renderer] Make R_RenderView private
This is actually a better solution to the renderer directly accessing
client code than provided by 7e078c7f9c.

Essentially, V_RenderView should not have been calling R_RenderView, and
CL_UpdateScreen should have been calling V_RenderView directly. The
issue was that the renderers expected the world entity model to be valid
at all times. Now, R_RenderView checks the world entity model's validity
and immediately bails if it is not, and R_ClearState (which is called
whenever the client disconnects and thus no longer has a world to
render) clears the world entity model. Thus R_RenderView can (and is)
now called unconditionally from within the renderer, simplifying
renderer-specific variants.

02ba3da0ba [vulkan] Ease writing of specialization data
While using binary data objects for specialization data works for bools
(as they can be 0 or -1), they don't work so well for numeric values due
to having to get the byte order correct and thus are not portable, and
difficult to get right.

Binary data is still supported, but the data can be written as a string
with an array(...) "constructor" expression taking any number of
parameters, with each parameter itself being an expression (though
values are limited at this stage).

Due to the plist format, quotes are required around the expression
("array(...)")

422ad2a6c9 [vulkan] Recreate lighting pvs sets when loading lights

8b85e422d7 [vulkan] Add a debug stack to the vulkan instance
The stack is arbitrary strings that the validation layer debug callback
prints in reverse order after each message. This makes it easy to work
out what nodes in a pipeline/render pass plist are causing validation
errors. Still have to narrow down the actual line, but the messages seem
to help with that.
Putting qfvPushDebug/qfvPopDebug around other calls to vulkan should
help out a lot, tool.
As a bonus, the stack is printed before debug_breakpoint is called, so
it's immediately visible in gdb.

2334798432 [vulkan] Make vulkan_use_validation easier more useful
Rather than just 0/1, it now acts as flags to control what messages are

all are supported (as well as raw numbers, but they're not checked for
validity). This makes vulkan_use_validation a bit easier to use and less

62f592b92c [input] Create an automatic imt switcher
An imt switcher automatically changes the context's active imt based on
a user specified list of binary inputs. The inputs may be either buttons
(indicated as +button) or cvars (bare name). For buttons, the
pressed/not pressed state is used, and cvars are interpreted as ints
being 0 or not 0. The order of the inputs determines the bit number of
the input, with the first input being bit 0, second bit 1, third bit 2
etc. A default imt is given so large switchers do not need to be fully
configured (the default imt is written to all states).

A context can have any number of switchers attached. The switchers can
wind up fighting over the active imt, but this seems to be something for
the "user" (eg, configuration system) to sort out rather than the
switcher code enforcing anything.

As a result of the inputs being treated as bits, a switcher with N
inputs will have 2**N states, thus there's a maximum of 16 inputs for
now as 65536 states is a lot of configuration.

Using a switcher, setting up a standard strafe/mouse look configuration
is fairly easy.

    imt_create key_game imt_mod
    imt_create key_game imt_mod_strafe imt_mod
    imt_create key_game imt_mod_freelook
    imt_create key_game imt_mod_lookstrafe imt_mod_freelook
    imt_switcher_create mouse key_game imt_mod_strafe +strafe lookstrafe +mlook freelook
    imt_switcher 0 imt_mod 2 imt_mod 4 imt_mod_freelook 8 imt_mod_freelook 12 imt_mod_freelook
    imt_switcher 6 imt_mod_lookstrafe 10 imt_mod_lookstrafe 14 imt_mod_lookstrafe
    in_bind imt_mod mouse axis 0 move.yaw
    in_bind imt_mod mouse axis 1 move.forward
    in_bind imt_mod_strafe mouse axis 0 move.side
    in_bind imt_mod_lookstrafe mouse axis 0 move.side
    in_bind imt_mod_freelook mouse axis 1 move.pitch

This takes advantage of imt chaining and the default imt for the
switcher (there are 8 states that use imt_mod_strafe).

The switcher name must be unique across all contexts, and every imt used
in a switcher must be in the switcher's context.

1ef99a9130 [input] Separate absolute and relative axis inputs
Combining absolute and relative inputs at the binding does not work well

(where frame here is each time the axis is read) but must accumulate the
relative updates between frames.

Other than the axis mode being incorrect, this seems to work quite
nicely.

af5d92708d [x11] Implement raw keyboard input via XInput2
UI key presses are still handled by regular X events, but in-game
"button" presses arrive via raw keyboard events. This gives transparent
handling of keyboard repeat (UI keys see repeat, game keys do not),
without messing with the server's settings (yay, that was most annoying
when it came to debugging), and the keyboard is never grabbed, so this
is a fairly user-friendly setup.

At first, I wasn't too keen on capturing them from the root window
(thinking about the user's security), but after a lot of investigation,
I found a post by Peter Hutterer
(http://who-t.blogspot.com/2011/09/whats-new-in-xi-21-raw-events.html)
commenting that root window events were added to XInput2 specifically
for games. Since application focus is tracked and unfocused key events
are dropped very early on, there's no way for code further down the
food-chain to know there even was an event, abusing the access would
require modifying the x11 input code, in which case all bets are off
anyway and any attempt at security anywhere in the code will fail,
meaning that nefarious progs code and the like shouldn't be a problem.

Other subsystems, especially low-level input drivers, need to know when

it seems the events are shared across multiple apps without any issue),
the evdev driver sees all the events thus needs to know when to drop
them.

e8a7e8218e [x11] Check hit barrier is valid before releasing pointer
It turns out to be possible to get a barrier event at the same time as a
configure notify event (which rebuilds the barriers), and trying to
release the pointer at such a time results in a bad barrier error and
program crash. Thus check the event barrier against the currently
existing barriers before attempting to release the pointer.

This does mean that a better mechanism for sequencing window
repositioning and barrier creation may be required.

This should be a much friendlier way of "grabbing" input, though I

There does seem to be a problem with the mouse sneaking out of the
top-right and bottom-left corners. I currently suspect a bug in the X
server, but further investigation is needed.

4391b87d04 [x11] Grab focus when the pointer enters the window
This is necessary in focus-follows-mouse environments (at least for
openbox, but it wouldn't surprise me if most other WMs behave the same
way) because the WMs don't set focus when the pointer is grabbed (which
XInput does before the WM sees the enter event). This is especially
important when the window is fullscreen on a multi-monitor setup as
there is no border to *maybe* catch the mouse before it enters the
window.

There's now IN_X11_Preinit, IN_X11_Postinit (both for want of better

initialization that needs to be done before window creation and between
window creation and mapping (ie, are very specific to X11 stuff) while
in_x11_init takes care of the setup for the input system. This proved
necessary in my XInput experimentation: a passive enter grab takes
effect only when the pointer enters the window, thus setting up the grab
with the pointer already in the window has no effect until the pointer
leaves the window and returns.

4898a44263 [console] Hook up new input system
This has smashed the keydest handling for many things, and bindings, but
seems to be a good start with the new input system: the console in
qw-client-x11 is usable (keyboard-only).

The button and axis values have been removed from the knum_t enum as
mouse events are separate from key events, and other button and axis
inputs will be handled separately.

keys.c has been disabled in the build as it is obsolute (thus much of
the breakage).

7d022db702 [util] Avoid Sys_Shutdown for IO signals
It turns out that calling Sys_Shutdown in the signal handler can cause
lockups due to the signal occurring at unsafe times. Fortunately, this is
just the IO related signals (INT, HUP, TERM, QUIT) as the others are
usually caused by actual errors and should not occur in system code thus
timing should not be an issue. However, care will need to be taken when it
comes to handling SIGINT or similar for breaking runaway progs code when
that time comes.

fed8f66824 [input] Rework logical buttons
kbutton_t is now in_button_t and has been moved to input.h. Also, a
button registration function has been added to take care of +button and
-button command creation and, eventually, direct binding of "physical"
buttons to logical buttons. "Physical" buttons are those coming in from
the OS (keyboard, mouse, joystick...), logical buttons are what the code
looks at for button state.

Additionally, the button edge detection code has been cleaned up such
that it no longer uses magic numbers, and the conversion to a float is
cleaner. Interestingly, I found that the handling is extremely
frame-rate dependent (eg, +forward will accelerate the player to full
speed much faster at 72fps than it does at 20fps). This may be a factor
in why gamers are frame rate obsessed: other games doing the same thing
would certainly feel different under varying frame rates.

192b76ddc6 [input] Remove closed device in correct place
Removing the device from the devices list after closing the device
could cause the device to be double-freed if something went wrong in the
device removal callback resulting in system shutdown which would then
close all open devices.

The device is removed from the list before the callback is called.

There's still a small opportunity for such in a multi-threaded
environment, but that would take device removal occurring at the same
time as the input system is shut down. Probably the responsibility of
the threaded environment rather than inputlib.

3b586fc0a6 [console] Untangle console and menu toggling
The recent changes to key handling broke using escape to get out of the

of the menu (escape) part of the coupling FIXME by implementing a
callback for the escape key (and removing key_togglemenu) and sorting
out the escape key handling in console. Seems to work nicely

6962c5948a [vulkan] Clean up some more unused bsp data
Since vulkan supports 32-bit indexes, there's no need for the

models (maps often had quite a bit more than 65536 vertices), though the
reduced GPU memory requirements of 16-bit indices does have its
advantages.

924c970868 [vulkan] Pre-compute the sun's PVS
Any sun (a directional light) is in the outside node, which due to not
having its own PVS data is visible to all nodes, but that's a tad
excessive. However, any leaf node with sky surfaces will potentially see
any suns, and leaf nodes with no sky surfaces will see the sun only if
they can see a leaf that does have sky surfaces. This can be quite
expensive to calculate (already known to be moderately expensive for
just the camera leaf node (singular!) when checking for in-map lights)

f7efcde7ab [vulkan] Clean up and document some of the bsp code
Getting close to understanding (again) how it all works. I only just
barely understood when I got vulkan's renderer running, but I really
need to understand for when I modify things for shadows. The main thing
hurdle was tinst, but that was dealt with in the previous commit, and
now it's just sorting out the mess of elechains and elementss.

c8e6f71a30 [renderer] Remove tinst from msurface_t
Its sole purpose was to pass the newly allocated instsurf when chaining
an instance model (ammo box, etc) surface, but using expresion
statements removes the need for such shenanigans, and even makes
msurface_t that little bit smaller (though a separate array would be
much better for cache coherence).

More importantly, the relevant code is actually easier to understand: I
spent way too long working out what tinst was for and why it was never
cleared.

0a847f92f1 [util] Use mmap/munmap for cmem internal alloc/free
This reduces the overhead needed to manage the memory blocks as the

alllocated from within one of the memory blocks it manages. While this
does slightly reduce the available cachelines within the first block (by
one or two depending on 32 vs 64 bit pointers), it removes the need for
an extra memory allocation (probably via malloc) for the superblock.

755ef524e4 [video] Use views instead of conwidth and conheight
conwidth and conheight have been moved into vid.conview (probably change
the name at some time), and scr_vrect has been replaced by a view as
well. This makes it much easier to create 2d elements that follow the
screen size (taking advantage of a view's gravity) which will, in the
end, make changing the window size easier.

a75c027b7f [ui] Add two view manipulation functions
One moves and resizes the view in one operation as a bit of an

absolute positions would change as well as the updated view's absolute
position.

4b1eb0d760 [sw] Speed up Draw_FadeScreen
It now processes 4 pixels at a time and uses a bit mask instead of a
conditional to set 3 of the 4 pixels to black. On top of the 4:1 pixel
processing and avoiding inner-loop conditional jumps, gcc unrolls the
loop, so Draw_FadeScreen itself is more than 4x as fast as it was. The
end result is about 5% (3fps) speedup to timedemo demo1 on my 900MHz
EEE Pc when nq has been hacked to always draw the fade-screen.

ae58a8ba5d [qwaq] Create a commandline-only version of qwaq
qwaq-curses has its place, but its use for running vkgen was really a
placeholder because I didn't feel like sorting out the different
initialization requirements at the time. qwaq-cmd has the (currently
unnecessary) threading power of qwaq-curses, but doesn't include any UI
stuff and thus doesn't need curses. The work also paves the way for
qwaq-x11 to become a proper engine (though sorting out its init will be
taken care of later).

db7e99d842 [audio] Allow output plugins to specify model
Output plugins can use either a push model (synchronous) or a pull

the combined render/output plugin it currently is (for #16) as now
snd_dma works with both models.

This gets the alsa target working nicely for mmapped outout. I'm not

the code from libasound's sample pcm.c, thus the uncertainty).
Non-mmapped output isn't supported yet, but the alsa target now works
nicely for pull rendering.

However, some work still needs to be done for recovery failure: either
disable the sound system, or restart the driver entirely (preferable).

fc907e232f [audio] Rework alsa to use a pull model
This brings the alsa driver in line with the jack render (progress
towards #16), but breaks most of the other drivers (for now: one step at
a time). The idea is that once the pull model is working for at least
one other target, the jack renderer can become just another target like
it should have been in the first place (but I needed to get the pull
model working first, then forgot about it).

Correct state checking is not done yet, but testsound does produce what
seems to be fairly good sound when it starts up correctly (part of the
state checking (or lack thereof), I imagine).

as the period size determines the number of samples in a submission

097d44e270 [util] Handle double shutdown
If Sys_Shutdown gets called twice, particularly if a shutdown callback
