2025-03-05powerpc: Move AT_HWCAP descriptions to ld diagnosticsAdhemerval Zanella1-0/+4
The ld.so diagnostics already prints AT_HWCAP values, but only in hexadecimal. To avoid duplicating the strings, consolidate the hwcap_names from cpu-features.h on a new file, dl-hwcap-info.h (and it also improves the hwcap string description with more values). For future AT_HWCAP3/AT_HWCAP4 extensions, it is just a matter to add them on dl-hwcap-info.c so both ld diagnostics and tunable filtering will parse the new values. Checked on powerpc64le-linux-gnu.

2023-08-01PowerPC: Influence cpu/arch hwcap features via GLIBC_TUNABLESMahesh Bodapati1-3/+8
This patch enables the option to influence hwcaps used by PowerPC. The environment variable, GLIBC_TUNABLES=glibc.cpu.hwcaps=-xxx,yyy,-zzz...., can be used to enable CPU/ARCH feature yyy, disable CPU/ARCH feature xxx and zzz, where the feature name is case-sensitive and has to match the ones mentioned in the file{sysdeps/powerpc/dl-procinfo.c}. Note that the hwcap tunables only used in the IFUNC selection. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
2022-04-10powerpc: Relocate stinfo->mainAlan Modra1-0/+6
start_addresses in sysdeps/powerpc/powerpc64/start.S is historical baggage that should disappear. Until someone does that, relocating stinfo->main by hand is one solution to the fact that the field may be unrelocated at the time it is accessed. This is similar to what is done for dynamic tags via the D_PTR macro. stinfo->init and stinfo->fini are zero in both powerpc64/start.S and powerpc32/start.S, so make it a little more obvious they are unused by passing NULLs to LIBC_START_MAIN. The makefile change is needed to pick up elf/dl-static-tls.h from dl-machine.h. Reviewed-by: Tulio Magno Quites Machado Filho <tuliom@linux.ibm.com>

2021-02-23nptl: Move elision implementations into libcFlorian Weimer1-2/+0
The elision interfaces are closely aligned between the targets that implement them, so declare them in the generic <lowlevellock.h> file. Empty .c stubs are provided, so that fewer makefile updates under sysdeps are needed. Also simplify initialization via __libc_early_init. The symbols __lll_clocklock_elision, __lll_lock_elision, __lll_trylock_elision, __lll_unlock_elision, __pthread_force_elision move into libc. For the time being, non-hidden references are used from libpthread to access them, but once that part of libpthread is moved into libc, hidden symbols will be used again. (Hidden references seem desirable to reduce the likelihood of transactions aborts.)
2020-01-03elf: Move vDSO setup to rtld (BZ#24967)Adhemerval Zanella1-1/+0
This patch moves the vDSO setup from libc to loader code, just after the vDSO link_map setup. For static case the initialization is moved to _dl_non_dynamic_init instead. Instead of using the mangled pointer, the vDSO data is set as attribute_relro (on _rtld_global_ro for shared or _dl_vdso_* for static). It is read-only even with partial relro. It fixes BZ#24967 now that the vDSO pointer is setup earlier than malloc interposition is called. Also, vDSO calls should not be a problem for static dlopen as indicated by BZ#20802. The vDSO pointer would be zero-initialized and the syscall will be issued instead. Checked on x86_64-linux-gnu, i686-linux-gnu, aarch64-linux-gnu, arm-linux-gnueabihf, powerpc64le-linux-gnu, powerpc64-linux-gnu, powerpc-linux-gnu, s390x-linux-gnu, sparc64-linux-gnu, and sparcv9-linux-gnu.

2019-06-19powerpc: Fix static-linked version of __ppc_get_timebase_freq [BZ #24640]Stan Shebs1-0/+2
__ppc_get_timebase_freq() always return 0 when using static linked glibc. This is a minimal example.c to reproduce: /******************************/ #include <inttypes.h> #include <stdint.h> #include <stdio.h> #include <sys/platform/ppc.h> int main() { uint64_t freq = __ppc_get_timebase_freq(); printf("Time Base frequency = %"PRIu64" Hz\n", freq); if (freq == 0) return -1; return 0; } /******************************/ Compile command: gcc -static example.c This bug has been reproduced, fixed and tested on all powerpc platforms (ppc32, ppc64 and ppc64le). The underlying code of __ppc_get_timebase_freq uses __get_timebase_freq that has a different implementation for shared and static version of glibc. In the static version, there is an incorrect sense in the if check for the fd returned when opening /proc/cpuinfo.

2015-03-25powerpc __tls_get_addr call optimizationAlan Modra1-0/+2
This patch is glibc support for a PowerPC TLS optimization, inspired by Alexandre Oliva's TLS optimization for other processors, http://www.lsd.ic.unicamp.br/~oliva/writeups/TLS/RFC-TLSDESC-x86.txt In essence, this optimization uses a zero module id in the tls_index GOT entry to indicate that a TLS variable is allocated space in the static TLS area. A special plt call linker stub for __tls_get_addr checks for such a tls_index and if found, returns the offset immediately. The linker communicates the fact that the special __tls_get_addr stub is used by setting a bit in the dynamic tag DT_PPC64_OPT/DT_PPC_OPT. glibc communicates to the linker that this optimization is available by the presence of __tls_get_addr_opt. tst-tlsmod2.so is built with -Wl,--no-tls-get-addr-optimize for tst-tls-dlinfo, which otherwise would fail since it tests that no static tls is allocated. The ld option --no-tls-get-addr-optimize has been available since binutils-2.20 so doesn't need a configure test. * NEWS: Advertise TLS optimization. * elf/elf.h (R_PPC_TLSGD, R_PPC_TLSLD, DT_PPC_OPT, PPC_OPT_TLS): Define.

2015-01-12powerpc: Add the lock elision using HTMAdhemerval Zanella1-0/+2
This patch adds support for lock elision using ISA 2.07 hardware transactional memory instructions for pthread_mutex primitives. Similar to s390 version, the for elision logic defined in 'force-elision.h' is only enabled if ENABLE_LOCK_ELISION is defined. Also, the lock elision code should be able to be built even with a compiler that does not provide HTM support with builtins. However I have noted the performance is sub-optimal due scheduling pressures.
2014-09-26Clean up gnu/lib-names.h generation (bug 14171).Joseph Myers1-2/+0
This patch eliminates the mixture of SONAME information in shlib-versions files and SONAME information used to generate gnu/lib-names.h in makefiles, with the information in the makefiles being removed so all this information comes from the shlib-versions files. So that gnu/lib-names.h supports multiple ABIs, it is changed to be generated on the same basis as gnu/stubs.h: when there are multiple ABIs, gnu/lib-names.h is a wrapper header (the same header installed whatever ABI is being built) and separate headers such as gnu/lib-names-64.h contain the substantive contents (only one such header being installed by any glibc build). The rules for building gnu/lib-names.h were moved from Makeconfig to Makerules because they need to come after sysdeps makefiles are included (now that "ifndef abi-variants" is a toplevel conditional on the rules rather than $(abi-variants) being evaluated later inside the commands for a rule). Tested for x86_64 and x86 that the installed shared libraries are unchanged by this patch, and examined the installed gnu/lib-names*.h headers by hand. Also tested the case of a single ABI (where there is just a single header installed, again like stubs.h) by hacking abi-variants to empty for x86_64.

2013-12-04PowerPC64 ELFv2 ABI 6/6: Bump ld.so soname version numberUlrich Weigand1-4/+7
To avoid having a ELFv2 binary accidentally picking up an old ABI ld.so, this patch bumps the soname to ld64.so.2. In theory (or for testing purposes) this will also allow co-installing ld.so versions for both ABIs on the same system. Note that the kernel will already be able to load executables of both ABIs. However, there is currently no plan to use that theoretical possibility in a any supported distribution environment ... Note that in order to check which ABI to use, we need to invoke the compiler to check the _CALL_ELF macro; this is done in a new configure check in sysdeps/unix/sysv/linux/powerpc/powerpc64/configure.ac, replacing the hard-coded value of default-abi in the Makefile.
