x86 arch provides the testing for conversion between tsc and perf time, the testing is located in x86 arch folder. Move this testing out from x86 arch folder and place it into the common testing folder, so allows to execute tsc testing on other architectures (e.g. Arm64). This patch removes the inclusion of "arch-tests.h" from the testing code, this can avoid building failure if any arch has no this header file. Committer testing: $ perf test -v tsc Couldn't bump rlimit(MEMLOCK), failures may take place when creating BPF maps, etc 70: Convert perf time to TSC : --- start --- test child forked, pid 4032834 mmap size 528384B 1st event perf time 165409788843605 tsc 336578703793868 rdtsc time 165409788854986 tsc 336578703837038 2nd event perf time 165409788855487 tsc 336578703838935 test child finished with 0 ---- end ---- Convert perf time to TSC: Ok $ Signed-off-by: Leo Yan <leo.yan@linaro.org> Acked-by: Jiri Olsa <jolsa@redhat.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Link: https://lore.kernel.org/r/20201019100236.23675-2-leo.yan@linaro.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |

README
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.
