** Description changed: + FFe: We would like to collect that information with 21.04 to get a + better view of supported hardware for the new hwcaps. The risk should + be minimal, only adding an extra flag, and the server side collecting + the data can handle that, according to Didier. + + pull request at https://github.com/ubuntu/ubuntu-report/pull/34 + we want to collect information which most recent hwcap is supported by a machine. The result should be a string like "x86-64-v2", "x86-64-v3", "x86-64-v4", "z13", "z14", "p9", "p10" depending on "ld-linux --help" output. The string should be empty for architectures without glibc hwcaps (currently armhf, arm64, i386, riscv64). The string should be empty if no specific hwcaps is supported (e.g. on a power8 machine). The - string should be "N/A" (not available), when trying to run ld-linux on a - release with glibc (<< 2.33). + string should be "" (empty), when trying to run ld-linux on a release + with glibc (<< 2.33). The string should be "-" (dash) when not having + any hwcaps mentioned. Note that lexical sorting won't work for "p9", "p10". if test -x /lib/x86_64-linux-gnu/ld-linux-x86-64.so.2; then - lddynload=/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2 + lddynload=/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2 elif test -x /lib/powerpc64le-linux-gnu/ld64.so.2; then - lddynload=/lib/powerpc64le-linux-gnu/ld64.so.2 + lddynload=/lib/powerpc64le-linux-gnu/ld64.so.2 elif test -x /lib/s390x-linux-gnu/ld64.so.1; then - lddynload=/lib/s390x-linux-gnu/ld64.so.1 + lddynload=/lib/s390x-linux-gnu/ld64.so.1 fi supported= if [ -n "$lddynload" ]; then - $lddynload --help 2>&1 | awk '/^Subdirectories/,/^$/' - supported=$($lddynload --help 2>&1 | awk '/^Subdirectories/,/^$/' | awk '/supported/ {print $1}') + $lddynload --help 2>&1 | awk '/^Subdirectories/,/^$/' + supported=$($lddynload --help 2>&1 | awk '/^Subdirectories/,/^$/' | awk '/supported/ {print $1}') fi Here, $supported has listed all supported hwcaps, not just the best supported one.
