Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux
![]() The shell tests should not redirect useful output to /dev/null, as that is done automatically by 'perf test' in non verbose mode, so remove that from the zstd comp/decomp test, fixing up verbose mode. Before: $ perf test zstd 68: Zstd perf.data compression/decompression : Ok $ perf test -v zstd 68: Zstd perf.data compression/decompression : --- start --- test child forked, pid 11956 -z, --compression-level[=<n>] Collecting compressed record file: Checking compressed events stats: test child finished with 0 ---- end ---- Zstd perf.data compression/decompression: Ok $ Now: $ perf test zstd 68: Zstd perf.data compression/decompression : Ok $ perf test -v zstd 68: Zstd perf.data compression/decompression : --- start --- test child forked, pid 12695 Collecting compressed record file: 0+500 records in 72+1 records out 37361 bytes (37 kB, 36 KiB) copied, 9.83796 s, 3.8 kB/s [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.001 MB /tmp/perf.data.rzq, compressed (original 0.004 MB, ratio is 3.679) ] Checking compressed events stats: # compressed : Zstd, level = 1, ratio = 4 COMPRESSED events: 3 test child finished with 0 ---- end ---- Zstd perf.data compression/decompression: Ok $ Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Alexey Budankov <alexey.budankov@linux.intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: https://lkml.kernel.org/n/tip-tp96618ds42zic94nlh0msz3@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |

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.
