Hi all -
Over the past several years, the tracing infrastructure has improved to the point that it incurs very little runtime overhead. The attached patchset migrates the useful options from the -trace configs to all of the other configs and ultimately removes the trace flavor entirely. This saves space for the kernel RPMs as well as conserves build resources.
Hi, on the other hand, I just wanted to point out, that DYN_FTRACE generates 22 bytes of nops on s390 (in comparison to 5 bytes on x86_64) in every function which actually can impact performance. But we don't care about s390 in openSUSE much, right? (We are to measure this on SLE yet.) thanks, - -- js suse labs -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIbBAEBAgAGBQJTS9oAAAoJEL0lsQQGtHBJY68P+KfYZgh3NN9Eir+PCUGaFbMH /7kczrWxSvTHrsemSvyaetlLZp0thy82Ws8ZLdoyQORttAQlUYavq102HNFAuYBr 95UtwPKHbtYKXxX5WYLlGzsmeIlce4rYbdqLIe17049rnWJnPynUUYPZ9KBX39R2 XwGkBz9p2ltp+YAT/8KhcPlB7mP1XNG+o8PV+FI+2ZUejFL7LC4aVNJx489evXSq n3RYGnpYHwejO9/vl+CoqL6f12tnxr4yo7KvMvaKJpeOxVXu9syx6GtMr5zSsn1g HeJav5Fb8uZmgn9YK+b+Z5gF9MGfwk0GW7ZM1JLgjatoJXMIaMv1LxSiDwFcsTC5 YO4/ecrwguSMC6U9vVXHv16RWkyEbsRzdxenlY6NzB8B5TSC7jqGbwnU+uDDahPG QHDJY1PFPsuQu9BJSky1MD7b96BxDJZKfI5WTUYX/XTrwwVdQVXrKUN66a+MRLN8 vNG2iliJgAsUOR+8f2jH96olAs2mD7QJ5vQJhlZkb0+yLigAJCeUQI/H6p/aFB2o JGrX49NoCxAoB7DY8IJIlGkxddmhwFHSKFr/ow26TXkmdJ+yHVJy22mSAMp+9ftE qG4azJ1vOPzP3wFfa900LHAgXuloNE8o28J9BLaCDXfTQpBbvG3VpaX0Zw3JpyL0 jhcCSMQBWMwwdkR7/Ok= =xvzW -----END PGP SIGNATURE----- -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org
