aebd9288cd Force thread count to 1 when pthreads is unavailable.
Don't want the thread count being misreported.

06ab36de3d Slight cleanup of winding allocation.
It seems gcc doesn't care if the & is present when calculating field
offsets, but it not being there bothered me very much and might as well use
our "standard" macro anyway.

c71eccfb10 Remove MAX_THREADS.
This fixes a buffer overflow with more than 4 threads.

d7c1bc8d02 Correct a comment.
I had gotten confused between figuring out the windings and writing the
comments, I guess.

88e5adcec6 Make the base vis multi-threaded.
Now multi-threaded qfvis is on par with tyrutils vis (differences usually
<1s, sometimes more, sometimes less).

32b6d15931 Use a sorted queue for portals.
qsort is used to sort the queue by nummightsee. At ~4ms for 20k portals, I
think it's affordable. Using a queue rather than scanning the portal list
each time loses the dynamic sorting when mightsee gets updated, but it
seemed to shave off 4s anyway (~207s to ~203s (maybe, yay random times)).

Another step towards threaded base-vis.

7e40981dcd Move the LeafThread setup to its own generic function.
This is for threading base-vis.

cb096c601d Use a per-portal rwlock for portal updates.
This should make qfvis scale a little better with cpu count.

c824e668ed Rework some of the pthread stuff.
Init/uninit is now separate from portal vising.
The global lock has a better name and is now a rwlock.
Use a separate lock for the stats.

134381f79b Reduce the locking in the portal completion code.
It doesn't seem to make much difference, but the less room for contention,
the better.

ffb6d628bd Simplify the pthreads detection macros. 2013-03-18 13:31:35 +09:00

1c20a49dba Use the recursive set allocator for mightsee.
This completely removes the lock used to protect the set allocation code
while keeping the use of the set api clean.

5a2ee06787 Reverse the winding for backside portals.
This is part 1 of another optimization from tyrutils vis. It seems that
just reversing the winding gives a tiny speedup.

f80ae52828 Make vis's ClipWinding const-correct. 2013-03-15 15:28:25 +09:00

77c858060d Add a bunch more statistics.
Now I know why sphere culling was a loss: 78% of all tested target portals
were trimmed by ClipToSeparators (50% eventually clipped away entirely).

5d6df082f2 Move the vis stats vars into thread data.
This should make the stats more reliable when running multi-threaded
(chains is still random, but it seems there are set access issues).

b9d71218f6 Use sphere culling in the base vis.
Base vis was done first for testing. Optimized base vis is down to ~12.4s
from ~16s (29% faster?).

3232c22795 Implement mightsee updates from tyrutils.
It doesn't seem to make much difference, but I suspect that's my set code
not being optimal for the job.

dbdfdb6d28 Add support for PRT2 portal files.
These seem to be identical to PRT1-AM but with a different count order in
the header. Taken from tyrutils-0.5.

81e4d3072c Plug a bunch of memory leaks.
Not that they really matter, but it makes reading valgrind's output a
little easier.

299ff8f575 Use set functions for qfvis.
While noticeably slower than the previous expanded set manipulation code,
this is much easier to read. I can worry about optimizing the set code when
I get qfvis behaving better.

f1aefc969d Fix some 64-bit mingw compile issues.
Just one more issue to fix (alloca), but with a hack, QF compiles (no clue
yet if it works: wine doesn't seem to be an option at this stage)

a2f2d4d949 "Check" for the availability of pthreads.
Unfortunately, just because the header is there doesn't mean anything will
actually work :(. Also, the check is based on the host vendor/os for now.
Yes, it's rather lame but it will do for now.

With this, QF will build on an almost fresh ps3toolchain install. Only two
"fixes" are needed:
 o  In $PS3DEV/ppu/powerpc64-ps3-elf: ln -s ../include sys-include
 o  libsamplerate cross-built and installed.

It's pretty useless in git.

c0f7b4ba37 Fix qfvis for android.
pthread_cancel is not (and will not be) implemented, so rework the thread
finalization to not need it.

de04e1b602 Lots of win32 (mingw cross) build fixes.
HTTP (curl) support is missing, but everything else builds.

49ea878ad9 Slightly more informative progress.
Display per-thread current portal number. Will get messy if there are more threads than the screen width can handle.

142defe9c0 Parameter consistency fixes.
Make the params for FreeWinding and CopyWinding consistent with those in
qfbsp. This fixes some doxygen warnings while I think about how best to
handle the duplicate code.

f4042c5b91 Make the bsp disk data structures type size independent.
However, this assumes float is always 32 bits.

Also use size_t for the *size fields in bsp_t and clean up the mess.
