* [PowerPC64LE] Use a shared LIBC_ARCH for powerpc64le.Brandon Bergren2020-09-231-2/+2
| | | | | | | | | | | | | | | Given that we have converted to ELFv2 for BE already, endianness is the only difference between the two ARCHs. As such, there is no need to differentiate LIBC_ARCH between the two. Combining them like this lets us avoid needing to have two copies of several bits for no good reason.

* Strip __RCSID() and __SCCSID() strings by default when building libc.John Baldwin2018-07-031-2/+4
| | | | | | | | | | | | | This is in preparation for changes to update the various ID strings in libc's source. CSRG ID strings will use __SCCSID() and there are some existing uses of __RCSID() for NetBSD ID strings already. These are generally under either an explicit #if 0 or an #ifdef LIBC_SCCS so are off by default and this change preserves that existing behavior.

The change in performance over a locally mounted UFS filesystem was negligible in my testing, but this may more positively impact other filesystems like NFS.

* Implement userspace gettimeofday(2) with HPET timecounter.Konstantin Belousov2016-08-171-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now, userspace (fast) gettimeofday(2) on x86 only works for RDTSC. For older machines, like Core2, where RDTSC is not C2/C3 invariant, and which fall to HPET hardware, this means that the call has both the penalty of the syscall and of the uncached hw behind the QPI or PCIe connection to the sought bridge. Nothing can me done against the access latency, but the syscall overhead can be removed. System already provides mappable /dev/hpetX devices, which gives straight access to the HPET registers page. Add yet another algorithm to the x86 'vdso' timehands. Libc is updated to handle both RDTSC and HPET. For HPET, the index of the hpet device to mmap is passed from kernel to userspace, index might be changed and libc invalidates its mapping as needed. Remove cpu_fill_vdso_timehands() KPI, instead require that timecounters which can be used from userspace, to provide tc_fill_vdso_timehands{,32}() methods. Merge i386 and amd64 libc/<arch>/sys/__vdso_gettc.c into one source file in the new libc/x86/sys location. __vdso_gettc() internal interface is changed to move timecounter algorithm detection into the MD code. Measurements show that RDTSC even with the syscall overhead is faster than userspace HPET access. But still, userspace HPET is three-four times faster than syscall HPET on several Core2 and SandyBridge machines.

The fcntl(2) contains compatibility code to handle kernels before the struct flock was changed during the 8.x CURRENT development. The shims were reasonable to allow easier revert to the older kernel at that time. Now, two or three major releases later, shims do not serve any purpose. Such old kernels cannot handle current libc, so revert the compatibility code. Make padded syscalls support conditional under the COMPAT6 config option. For COMPAT32, the syscalls were under COMPAT6 already. Remove WITHOUT_SYSCALL_COMPAT build option, which only purpose was to (partially) disable the removed shims.

Instead, functions calls are indirected through the interposing table, similar to how pthread stubs in libc are already done. Libc by default points either to syscall trampolines or to existing libc implementations. On libthr load, libthr rewrites the pointers to the cancellable implementations already in libthr. The interposition table is separate from pthreads stubs indirection table to not pull pthreads stubs into static binaries. - Postpone the malloc(3) internal mutexes initialization until libthr is loaded. This avoids recursion between calloc(3) and static pthread_mutex_t initialization. - Reinstall signal handlers with wrapper on libthr load. The _rtld_is_dlopened(3) is used to avoid useless calls to sigaction(2) when libthr is statically referenced from the main binary. In the process, fix openat(2), swapcontext(2) and setcontext(2) interposing. The libc symbols were exported at different versions than libthr interposers. Export both libc and libthr versions from libc now, with default set to the higher version from libthr. Remove unused and disconnected swapcontext(3) userspace implementation from libc/gen.
