2022-10-20	tuklib_cpucores: Use HW_NCPUONLINE on OpenBSD.	Lasse Collin	1	-0/+5
	On OpenBSD the number of cores online is often less than what HW_NCPU would return because OpenBSD disables simultaneous multi-threading (SMT) by default. Thanks to Christian Weisgerber.
2020-02-24	tuklib: Omit an unneeded <sys/types.h> from a tests.	Lasse Collin	1	-1/+0
	tuklib_cpucores.c and tuklib_physmem.c don't include <sys/types.h> even via other files in this package, so clearly that header isn't needed in the tests either (no one has reported build problems due to a missing header in a .c file).
2016-10-24	tuklib_cpucores: Add support for sched_getaffinity().	Lasse Collin	1	-1/+29
	It's available in glibc (GNU/Linux, GNU/kFreeBSD). It's better than sysconf(_SC_NPROCESSORS_ONLN) because sched_getaffinity() gives the number of cores available to the process instead of the total number of cores online. As a side effect, this commit fixes a bug on GNU/kFreeBSD where configure would detect the FreeBSD-specific cpuset_getaffinity() but it wouldn't actually work because on GNU/kFreeBSD it requires using -lfreebsd-glue when linking. Now the glibc-specific function will be used instead. Thanks to Sebastian Andrzej Siewior for the original patch and testing.
2015-03-27	Fix CPU core count detection on QNX.	Lasse Collin	1	-4/+11
	It tried to use sysctl() on QNX but - it broke the build because sysctl() needs -lsocket on QNX; - sysctl() doesn't work for detecting the core count on QNX even if it compiled. sysconf() works. An alternative would have been to use QNX-specific SYSPAGE_ENTRY(num_cpu) from <sys/syspage.h>. Thanks to Ole André Vadla Ravnås.
2015-02-10	tuklib_cpucores: Use cpuset_getaffinity() on FreeBSD if available.	Lasse Collin	1	-1/+22
	In FreeBSD, cpuset_getaffinity() is the preferred way to get the number of available cores. Thanks to Rui Paulo for the patch. I edited it slightly, but hopefully I didn't break anything.
2013-08-03	Windows: Add Windows support to tuklib_cpucores().	Lasse Collin	1	-2/+17
	It is used for Cygwin too. I'm not sure if that is a good or bad idea. Thanks to Vincent Torri.
2010-05-10	Updates to tuklib_physmem and tuklib_cpucores.	Lasse Collin	1	-6/+27
	Don't use #error to generate compile error, because some compilers actually don't take it as an error. This fixes tuklib_physmem on IRIX. Fix incorrect error check for sysconf() return values. Add AIX, HP-UX, and Tru64 specific code to detect the amount RAM. Add HP-UX specific code to detect the number of CPU cores. Thanks a lot to Peter O'Gorman for initial patches, testing, and debugging these fixes.
2010-01-12	Add IRIX-specific code to tuklib_physmem and tuklib_cpucores.	Lasse Collin	1	-2/+9
	This is untested but it will get tested soon and, if needed, fixed before 5.0.0. Thanks to Stuart Shelton.
2009-11-20	Update tuklib_cpucores.m4 and tuklib_physmem.m4 from tuklib,	Lasse Collin	1	-13/+18
	which now use AC_CACHE_CHECK. Using the cache variable, configure now warns if there is no method to detect the amount of RAM and recommends using --enable-assume-ram.
2009-09-19	Various changes.	Lasse Collin	1	-0/+72
	Separate a few reusable components from XZ Utils specific code. The reusable code is now in "tuklib" modules. A few more could be separated still, e.g. bswap.h. Fix some bugs in lzmainfo. Fix physmem and cpucores code on OS/2. Thanks to Elbert Pol for help. Add OpenVMS support into physmem. Add a few #ifdefs to ease building XZ Utils on OpenVMS. Thanks to Jouk Jansen for the original patch.
