* linux: Enable vDSO for static linking as default (BZ#19767)Adhemerval Zanella2019-08-051-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch assumes static vDSO is supported as default, it is now supported on all current architectures that support vDSO. It allows removing both ALWAYS_USE_VSYSCALL define, which an architecture requires to explicit define and USE_VSYSCALL (which defines vDSO only for shared or if architecture defines ALWAYS_USE_VSYSCALL). Checked with a build against all affected ABIs.

* powerpc: Only enable TLE with PPC_FEATURE2_HTM_NOSCAdhemerval Zanella2018-09-211-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux from 3.9 through 4.2 does not abort HTM transaction on syscalls, instead it suspend and resume it when leaving the kernel. The side-effects of the syscall will always remain visible, even if the transaction is aborted. This is an issue when transaction is used along with futex syscall, on pthread_cond_wait for instance, where the futex call might succeed but the transaction is rolled back leading the pthread_cond object in an inconsistent state. Glibc used to prevent it by always aborting a transaction before issuing a syscall. Linux 4.2 also decided to abort active transaction in syscalls which makes the glibc workaround superfluous. Worse, glibc transaction abortion leads to a performance issue on recent kernels where the HTM state is saved/restore lazily (v4.9). By aborting a transaction on every syscalls, regardless whether a transaction has being initiated before, GLIBS makes the kernel always save/restore HTM state (it can not even lazily disable it after a certain number of syscall iterations). Because of this shortcoming, Transactional Lock Elision is just enabled when it has been explicitly set (either by tunables of by a configure switch) and if kernel aborts HTM transactions on syscalls (PPC_FEATURE2_HTM_NOSC). It is reported that using simple benchmark [1], the context-switch is about 5% faster by not issuing a tabort in every syscall in newer kernels. Checked on powerpc64le-linux-gnu with 4.4.0 kernel (Ubuntu 16.04). * NEWS: Add note about new TLE support on powerpc64le. * sysdeps/powerpc/nptl/tcb-offsets.sym (TM_CAPABLE): Remove. * sysdeps/powerpc/nptl/tls.h (tcbhead_t): Rename tm_capable to __ununsed1.

* Add INLINE_SYSCALL_ERROR_RETURN_VALUEH.J. Lu2015-10-131-0/+1

In most cases, there are no errors. But we still call __x86.get_pc_thunk.reg.

* Consolidate sched_getcpuAdhemerval Zanella2015-06-091-0/+1
| | | | | | | | This patch consolidates the sched_getcpu implementations across all arches (except tile, which requires its own). This patch removes the powerpc, x86_64 and x32 specific files and change the default linux one to use INLINE_VSYSCALL where possible (for ports that implements it).
* Consolidate vDSO macros and usageAdhemerval Zanella2015-05-261-72/+23
| | | | | | | | | | | | | | | | This patch consolidate the Linux vDSO define and usage across all ports that uses it. The common vDSO definitions and calling through {INLINE/INTERNAL}_VSYSCALL macros are moved to a common header sysdep-vdso.h and vDSO name declaration and prototype is defined using a common macro. Also PTR_{MANGLE,DEMANGLE} is added to ports that does not use them for vDSO calls (aarch64, powerpc, s390, and tile) and thus it will reflect in code changes. For ports that already implement pointer mangling/demangling in vDSO system (i386, x32, x86_64) this patch is mainly a code refactor. Checked on x32, x86_64, x32, ppc64le, and aarch64.
* powerpc: abort transaction in syscallsAdhemerval Zanella2015-01-121-0/+1
| | | | | | | | | | | Linux kernel powerpc documentation states issuing a syscall inside a transaction is not recommended and may lead to undefined behavior. It also states syscalls does not abort transactoin neither they run in transactional state. To avoid side-effects being visible outside transactions, GLIBC with lock elision enabled will issue a transaction abort instruction just before all syscalls if hardware supports hardware transactions.

* PowerPC: Rename __kernel_vdso_get_tbfreq to __kernel_get_tbfreq.Anton Blanchard2013-01-181-13/+15
| | | | | | | | | | In order for the __kernel_get_tbfreq vDSO call to work the INTERNAL_VSYSCALL_NCS macro needed to be updated to prevent it from assuming an integer return type (since the timebase frequency is a 64-bit value) by specifying the type of the return type as a macro parameter. The macro then specifically declares the return value as a 'register' (or implied pair) of the denoted type. The compiler is then informed that this register (or implied pair) is to be used for the return value.
