Except arch x86, the function rseq_offset_deref_addv is not defined. The function test_membarrier_manager_thread call rseq_offset_deref_addv produces a build error. The RSEQ_ARCH_HAS_OFFSET_DEREF_ADD should contain all the code for the MEMBARRIER_CMD_PRIVATE_EXPEDITED_RSEQ. If the other Arch implements this feature, defined RSEQ_ARCH_HAS_OFFSET_DEREF_ADD in the header file to ensure that this feature is available. Following build errors: param_test.c: In function ‘test_membarrier_worker_thread’: param_test.c:1164:10: warning: implicit declaration of function ‘rseq_offset_deref_addv’ ret = rseq_offset_deref_addv(&args->percpu_list_ptr, ^~~~~~~~~~~~~~~~~~~~~~ /tmp/ccMj9yHJ.o: In function `test_membarrier_worker_thread': param_test.c:1164: undefined reference to `rseq_offset_deref_addv' param_test.c:1164: undefined reference to `rseq_offset_deref_addv' collect2: error: ld returned 1 exit status make: *** [/selftests/rseq/param_test_benchmark] Error 1 Signed-off-by: Xingxing Su <suxingxing@loongson.cn> Acked-by: Mathieu Desnoyers <mathieu.desnoyers@efficios.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org> |

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
