* Created tunable to force small pages on stack allocation.Cupertino Miranda2023-04-201-0/+1
| | | | | | | | | | Created tunable glibc.pthread.stack_hugetlb to control when hugepages can be used for stack allocation. In case THP are enabled and glibc.pthread.stack_hugetlb is set to 0, glibc will madvise the kernel not to use allow hugepages for stack allocations.

| | | | | | | | | | | | | | | | | | | | | | | I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 7061 files FOO. I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah. I don't know why I run into these diagnostics whereas others evidently do not. remote: *** 912-#endif remote: *** 913: remote: *** 914- remote: *** error: lines with trailing whitespace found ... remote: *** error: sysdeps/unix/sysv/linux/statx_cp.c: trailing lines
* Remove "Contributed by" linesSiddhesh Poyarekar2021-09-031-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | We stopped adding "Contributed by" or similar lines in sources in 2012 in favour of git logs and keeping the Contributors section of the glibc manual up to date. Removing these lines makes the license header a bit more consistent across files and also removes the possibility of error in attribution when license blocks or files are copied across since the contributed-by lines don't actually reflect reality in those cases. Move all "Contributed by" and similar lines (Written by, Test by, etc.) into a new file CONTRIBUTED-BY to retain record of these contributions. These contributors are also mentioned in manual/contrib.texi, so we just maintain this additional record as a courtesy to the earlier developers. The following scripts were used to filter a list of files to edit in place and to clean up the CONTRIBUTED-BY file respectively. These were not added to the glibc sources because they're not expected to be of any use in future given that this is a one time task: https://gist.github.com/siddhesh/b5ecac94eabfd72ed2916d6d8157e7dc https://gist.github.com/siddhesh/15ea1f5e435ace9774f485030695ee02 Reviewed-by: Carlos O'Donell <carlos@redhat.com>
* nptl: Add glibc.pthread.stack_cache_size tunableFlorian Weimer2021-06-281-4/+4
| | | | | | | The valgrind/helgrind test suite needs a way to make stack dealloction more prompt, and this feature seems to be generally useful. Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org>
* nptl: Move semi-public __pthread_get_minstack symbol into libcFlorian Weimer2021-05-211-0/+17
| | | | | | | | | No abilist updates here because it is a GLIBC_PRIVATE symbol. It's also necessary to move nptl_version into pthread_create, so that it still ends up in static binaries. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* nptl: Move stack cache management, __libpthread_freeres into libcFlorian Weimer2021-05-111-0/+130
This replaces the FREE_P macro with the __nptl_stack_in_use inline function. stack_list_del is renamed to __nptl_stack_list_del, stack_list_add to __nptl_stack_list_add, __deallocate_stack to __nptl_deallocate_stack, free_stacks to __nptl_free_stacks. It is convenient to move __libpthread_freeres into libc at the same time. This removes the temporary __default_pthread_attr_freeres export and restores full freeres coverage for __default_pthread_attr. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
