9d819254d4 [util] Make a number of improvements to SEB
Attempting to vis ad_tears drags a few lurking bugs out of
SmallestEnclosingBall_vf: poor calculation of 2-point affine space, poor
handling of duplicate points and dropped support points, poor
calculation of the new center (related to duplicate points), and
insufficient iterations for large point sets. qfvis (modified for
cluster spheres) now loads ad_tears.

fe98a513bc [util] Add a function to check hunk pointers

6d312aaa63 [simd] Check the distance to the affine point
As per usual, fp math finds a way to confound any epsilon test. So
rather than relying entirely on test_support_points, check the distance
from the sphere center to the affine point and break out of the loop if
the distance is small enough (< 1% of the current radius). This allows
qfvis to load ad_tears without hacks.

45aa8e6504 [util] Loosen affine test epsilon for SEB
Scaling the checks by 1e-6 was a little too tight for very small
triangles, but 1e-5 seems to work well. This fixes SEB getting stuck for
a ridiculously small (for quake) triangle in ad_tears (probably resulted
from some bad math in qfbsp when generating the portal file from the
bsp).

54604d9aa2 [util] Make hunk (optionally) thread-safe
For now, the functions check for a null hunk pointer and use the global
hunk (initialized via Memory_Init) if necessary. However, Hunk_Init is
available (and used by Memory_Init) to create a hunk from any arbitrary
memory block. So long as that block is 64-byte aligned, allocations
within the hunk will remain 64-byte aligned.

9e2c474d38 [model] Ensure the pvs is not inverted
Mod_DecompressVis_set (via Mod_LeafPVS_set) can be used to recycle pvs
sets, but the set may have been set to everything at some stage, which
is implemented by inverting the set (making the set infinite) and having
1-bits remove elements from the set. This is most definitely not wanted
for pvs :)

Currently undecided what to do about Mod_DecompressVis_mix, thus the
fixme.

Fixes the flickering lights in any map where the camera is out of the
map for a single frame (eg, start.bsp, The Catacombs (hipnotic, hip2m3)).

163d147044 [util] Give set_count a >8x speed boost
I knew counting bits individually was slow, but it never really mattered
until now. However, I didn't expect such a dramatic boost just by going
to mapping bytes to bit counts. 16-bit words would be faster still, but
the 64kB lookup table would probably start hurting cache performance,
and 32-bit words (4GB table) definitely would ruin the cache. The
universe isn't big enough for 64-bits :)

50740c1014 [model] Remove the confusion about numleafs
The fact that numleafs did not include leaf 0 actually caused in many
places due to never being sure whether to add 1. Hopefully this fixes

49c3dacbbc [util] Rename set_size to set_count
After seeing set_size and thinking it redundant (thought it returned the
capacity of the set until I checked), I realized set_count would be a
much better name (set_count (node->successors) in qfcc does make much
more sense).

f47e03e606 [model] Remove 64k limit on visible leafs
Modern maps can have many more leafs (eg, ad_tears has 98983 leafs).
Using set_t makes dynamic leaf counts easy to support and the code much
easier to read (though set_is_member and the iterators are a little
slower). The main thing to watch out for is the novis set and the set
returned by Mod_LeafPVS never shrink, and may have excess elements (ie,
indicate that nonexistent leafs are visible).

03921c03c5 [util] Expose set_expand and fix an out-by-one bug
Having set_expand exposed is useful for loading data into a set.

However, it turns out there was a bug in its size calculation in that
when the requested set size was a multiple of SET_BITS (and greater than
the current set size), the new set size one be SET_BITS larger than
requested. There's now some tests for this :)

7995f59a90 [vulkan] Set the 2d near distance to 0
-999999 seems to be a hold-over from the software renderer passed
through both gl renderers. I guess it didn't matter in the gl renderers
due to various draw hacks, but it made quite a difference in vulkan.
Fixes the view model covering the hud.

56c2fa380b [vulkan] Implement view model rendering
Quake just looked wrong without the view model. I can't say I like the
way the depth range is hacked, but it was necessary because the view
model needs to be processed along with the rest of the alias models
(didn't feel like adding more command buffers, which I imagine would be
expensive with the pipeline switching).

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

5864406f4d [vulkan] Enable all lights when camera out of map

6962c5948a [vulkan] Clean up some more unused bsp data
Since vulkan supports 32-bit indexes, there's no need for the
shenanigans the EGL-based glsl renderer had to go through to render bsp
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
blocks are guaranteed to be page-aligned. Also, the superblock is now
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

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

qwaq-curses has its place, but its use for running vkgen was really a

unnecessary) threading power of qwaq-curses, but doesn't include any UI

qwaq-x11 to become a proper engine (though sorting out its init will be
taken care of later).

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

79825db539 [audio] Clean up alsa init and add error checking
This gets the alsa target working nicely for mmapped outout. I'm not
certain, but I think it will even deal with NPOT buffer sizes (I copied
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).

The calculation was including the bits per sample, which makes no sense
as the period size determines the number of samples in a submission
chunk (and thus latency). For now, set it to around 5.5ms (will probably
need a cvar).

097d44e270 [util] Handle double shutdown
If Sys_Shutdown gets called twice, particularly if a shutdown callback
hangs and the program is killed with INT or QUIT, shutdown_list would be
in an invalid state. Thus, get the required data (function pointer and
data pointer) from the list element, then unlink the element before
calling the function. This ensures that a reinvocation of Sys_Shutdown
continues from the next callback or ends cleanly. Fixes a segfault when
killing testsound while using the oss output (it hangs on shutdown).

However, this is a bit of a band-aid in that the code for global defs

0da127b822 [gamecode] Fix bad progs strings intialization
The merge with the improvements I made while hacking on csqc (still
undecided as to whether to continue that project) resulted in the size
of the progs string area getting mangled when no heap was allocated for
the progs due to a null zone pointer being used in some pointer
arithmetic. Fixes random(!!!) invalid string error in qfprogs.

6fea5f5e1a [build] Add -Wformat-non-literal option
While this caused some trouble for pr_strings and configurable strftime
(evil hacks abound), it's the result of discovering an ancient (from

that somehow got past months of trial-by-fire testing (origin understood
thanks to the warning finding it).

This is for the conversion /to/ paletted textures. The conversion is
necessary for csqc support. In the process, the conversion has been sped up

measured the difference yet, but Mr Fixit does seem to load much faster for
the sw renderer than it did before the change (many months old memory).

The server edict arrays are now stored outside of progs memory, only the

There were actually several problems: translucency wasn't using or

Light styles and shadows aren't implemented yet.

The map's entities are used to create the lights, and the PVS used to

That could do with some more improvements (eg, checking if a leaf is
outside a spotlight's cone), but the concept seems to work.

fbc1bd9f6e [renderer] Clean up entity_t to a certain extent
This is the first step towards component-based entities.

There's still some transform-related stuff in the struct that needs to
be moved, but it's all entirely client related (rather than renderer)
and will probably go into a "client" component. Also, the current
components are directly included structs rather than references as I
didn't want to deal with the object management at this stage.

As part of the process (because transforms use simd) this also starts
the process of moving QF to using simd for vectors and matrices. There's
now a mess of simd and sisd code mixed together, but it works
surprisingly well together.

55104ac430 [util] Allow "any type" results for cexpr
Setting the result type cexpr_exprval tells cexpr to simply return whoe

5535d1f8e6 [util] Keep track of plist dictionary key order
The order in which keys are added to the dictionary object is

0dcd946063 [util] Add plist parser for dictionary -> array
PL_ParseLabeledArray works the same way as PL_ParseArray, but instead
takes a dictionary object. The keys of the items are ignored, and the
order is not preserved (at this stage), but this is a cleaner solution
to getting an array of objects when the definitions of those objects
need to be accessible by name as well.

c536a363ec [vulkan] Remove namehack.h
Never really wanted in the first place (back when I did the plugin
renderers), but I didn't feel like doing the required work to avoid it
at the time. At least with Vulkan being a fresh start in an environment
that's already plugin-friendly, there was no real work involved. I'll
get to the other renderers eventually (especially now that I know gdb
does the right thing when there are multiple functions with the same
name).

It's not entirely there yet, but the basics are working. Work is still

bc7858bb87 [model] Move parent pointer out of leaf/node struct
The node struct was 72 bytes thus two cache line. Moving the pointer
into the brush model data block allows nodes to fit in a single cache
line (not that they're aligned yet, but that's next). It doesn't seem to
have made any difference to performance (at least in the vulkan
renderer), but it hasn't hurt, either, as the only place that needed the
parent pointer was R_MarkLeaves.

Bill Currie
d6b678ac78 [vulkan] Implement team colors
It's not quite as expected, but that may be due to one of msaa, the 0-15
range in the palette not being all the way to white, the color gradients
being not quite linear (haven't checked yet) or some combination of the
above. However, it's that what should be yellow is more green. At least
the zombies are no longer white and the ogres don't look like they're
wearing skeleton suits.

This is a big step towards a cleaner api. The struct reference in

It now takes a context pointer (opaque data) that holds the buffers it

c989c8a6b6 [vulkan] Rewrite staging buffer packet handling
It now uses the ring buffer code I wrote for qwaq (and forgot about,

8078e10ea1 [vulkan] Make frame-buffers independent of swapchain
This is more correct as the environment (X11 etc) might provide more
swapchain images than we want: 3 frames in flight is generally
considered a good balance between saturating the hardware and latency.

5186d3ae49 [vulkan] Rework draw to use a context struct
Cleans up global space and makes it usable in multiple contexts. Also,
max quads dropped to 32k as each frame now has its own vertex buffer to
avoid issues with vertex overwrites (which I have seen). However, all
vertex buffers are in the one memory/buffer object (using offsets) and
the index buffer has been moved into a device-local memory object.

904a91c0b7 [vulkan] Use only one global staging buffer
I think I did two as a bit of a ring buffer, but the new ring buffer

enough)

09a10f80e1 [util] Add basic SIMD implemented vector functions
They take advantage of gcc's vector_size attribute and so only cross,
dot, qmul, qvmul and qrot (create rotation quaternion from two vectors)
are needed at this stage as basic (per-component) math is supported
natively by gcc.

The provided functions work on horizontal (array-of-structs) data, ie a
vec4d_t or vec4f_t represents a single vector, or traditional vector
layout. Vertical layout (struct-of-arrays) does not need any special
functions as the regular math can be used to operate on four vectors at
a time.

Functions are provided for loading a vec4 from a vec3 (4th element set
to 0) and storing a vec4 into a vec3 (discarding the 4th element).

With this, QF will require AVX2 support (needed for vec4d_t). Without
support for doubles, SSE is possible, but may not be worthwhile for
horizontal data.

Fused-multiply-add is NOT used because it alters the results between
unoptimized and optimized code, resulting in -mfma really meaning
-mfast-math-anyway. I really do not want to have to debug issues that
occur only in optimized code.

af814ff9a8 [util] Add a cache-line aligned memory allocator
This was inspired by
Hoard: A Scalable Memory Allocator
  for Multithreaded Applications

 Emery D. Berger, Kathryn S. McKinley, Robert D. Blumofe, Paul R.
 Wilson,

It's not anywhere near the same implementation, but it did take a few
basic concepts. The idea is twofold:
1) A pool of memory from which blocks can be allocated and then freed
en-mass and is fairly efficient for small (4-16 byte) blocks
2) Tread safety for use with the Vulkan renderer (and any other
multi-threaded tasks).

However, based on the Hoard paper, small allocations are cache-line
aligned. On top of that, larger allocations are page aligned.

I suspect it would help qfvis somewhat if I ever get around to tweaking
qfvis to use cmem.

with very small angles. This implementation will produce a usable
quaternion below 0.00255 degrees (though it will be slightly larger than
unit). Unity's failed such that I could see KSP's skybox snap while it

6d5ffa9f8e [build] Move to non-recursive make
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).

In testing variable fw/precision in PR_Sprintf, I got a nasty reminder
of the limitations of the current progs ABI: passing @args to another QC
function does not work because the args list gets trampled but the
called function's locals. Thus, the need for a va_copy. It's not quite
the same as C's as it returns the destination args instead of copying
like memcpy, but it does copy the list from the source args to a
temporary buffer that is freed when the calling function returns.

fea6381574 [gamecode] Rework debug type handling a little
Type encodings are used whenever they are available. For now, if they

af37b660e8 [ruamoko] Push the forwarded args block

f290b115a5 [gamecode] Add function PR_PushTempString
This "pushes" a temp string onto the callee's stack frame after removing

is likely to ensue if a string is pushed that was allocated in an

7d43bd5c66 [gamecode] Add function PR_AllocTempBlock()
PR_AllocTempBlock() works the same way as PR_SetTempString(), except
that it takes a size parameter and always allocates (never tries to
merge). This is, in a way, abusing the string system, but I needed a way
to allocate a block of progs memory that would be automatically freed
when the current frame ended. The biggest abuse is the need to cast away
the const of PR_GetString()'s return value.

a487595149 [ruamoko,libr] Begin implementation of __obj_forward
libr supplies an __obj_forward definition that links to a builtin, but

The builtin version currently simply errors out (rather facetiously),
but only as a stub to allow progs to load.

78f552aa87 [ruamoko] Initialize static instances
This is one step closer to implementing conformsToProtocol. However,
protocols are not yet initialized correctly: they are not registered,
nor are their selectors.

While the static initializer list pointer was not written previously,
the module struct always came immediately after the symbols struct, and
the module version has so far always been 0. Thus, the list pointer is
correctly 0 for older progs and there's no need for a version bump.

PR_SaveParams() is required for implementing the +initialize diversion
used by Objective-QuakeC because builtins do not have local def spaces

is entirely possible for a call to +initialize to trigger another call
to +initialize, thus the need for stacking parameter stashes. As a
bonus, this implementation cleans up some fields in progs_t.

The better accuracy is for specific cases (90 degree rotations around a

I've decided that setting pr.max_edicts and pr.zone_size as part of the

sense. For one, it is unlikely for the limits to change every time progs is
reloaded. Also, they seem to be a property of the VM rather than the progs.
However, there is nothing stopping the caller from updating max_edicts and
zone_size every call.

ab3f554a0e Limit the search for lit and ent files.
The search for these files will stop in the vpath that contains the .bsp
file to which they belong. This will prevent problems with
id1/maps/start.lit being used for shadows/maps/start.bsp.

8bea6a66ca Create _QFS_VOpenFile and QFS_VOpenFile.
_QFS_VOpenFile is actually _QFS_FOpenFile reimplemented to take vpath start
and end parameters so the search can be limited. QFS_VOpenFile,
_QFS_FOpenFile, and QFS_FOpenFile are all wrappers for _QFS_VOpenFile.

3efb0c538f Separate file search from loading.
QFS_LoadFile (and its wrappers) now  take a file handle rather than a

f05c7179c3 Split up the search paths into vpath chunks.
A vpath is the union of all locations searched for a file in a single
gamedir (eg, shadows, id1 etc). This is a necessary step to preventing
problems like id1/maps/start.lit being used for shadows/maps/start.bsp.

However, QFS_FilelistFill still needs to be reworked as it does not compile
yet (testing was done with a gutted QFS_FilelistFill).

a419fb2c92 Ensure the vertex coord attribute is attribute 0.
It seems mesa still has the bug where non-array attributes don't work
when set as attribute 0, and that the allocation order changed sometime

alias models on my eeepc.

b269338947 Start using the new shader system.
So far, alias model rendering is the only victim, but things are working,

96c40cb9a1 Add basic support for shader "effects".
Again, based on The OpenGL Shader Wrangler. The wrangling part is not used

d912970cd3 Add support for segmented text files.
The idea comes from The OpenGL Shader Wrangler
(http://prideout.net/blog/?p=11). Text files are broken up into chunks via
lines beginning with -- (^-- in regex). The chunks are optionally named
with tags of the form: [0-9A-Za-z._]+. Unnamed chunks cannot be found.
Searching for chunks looks for the longest tag that matches the beginning
of the search tag (eg, a chunk named "Vertex" will be found with a search
tag of "Vertex.foo"). Note that '.' forms the units for the searc
("Vertex.foo" will not find "Vertex.f").

Unlike glsw, this implementation does not have the concept of effects keys
as that will be separate. Also, this implementation takes strings rather
than file names (thus is more generally useful).

27bb337a60 Use set_bits_t for holding set elements.
set_bits_t is now 64 bits for x86_64 machines (in linux, anyway). This gave
qfvis a huge speed boost: from ~815s to ~720s.

Also, expose some of the set internals so custom set operators can be
created.

b6d4766201 Add a function to find the circumsphere of up to 4 points.

0cd6d93030 Add a function to get the barycentric coords of a point.
It "works" for lines, triangles and tetrahedrons. For lines and triangles,
it gives the barycentric coordinates of the perpendicular projection of the

original point.

ca0b03687f Change the naming of ALLOC's free-list.
Rather than prefixing free_ to the supplied name, suffix _freelist to the

7c1d9d2b84 Make the angle and light hacks optional.

675db274a6 Use Sys_Error instead of PR_Error in ED_ConvertToPlist.
ED_ConvertToPlist is now independent of the progs engine as its only use

8e86ce9de9 Implement Sys_LongTime and wrap it with Sys_DoubleTime.
Sys_LongTime returns time in microseconds as a 64-bit int. Sys_DoubleTime
uses Sys_LongTime, converts to double and offsets 0 time by 4G (2**32).
This gives us consistent sub-microsecond precision for a very long time.
