Linus Torvalds add7695957 Perf events updates for v6.2: ... - Thoroughly rewrite the data structures that implement perf task context handling, with the goal of fixing various quirks and unfeatures both in already merged, and in upcoming proposed code. The old data structure is the per task and per cpu perf_event_contexts: task_struct::perf_events_ctxp[] <-> perf_event_context <-> perf_cpu_context ^ | ^ | ^ `---------------------------------' | `--> pmu ---' v ^ perf_event ------' In this new design this is replaced with a single task context and a single CPU context, plus intermediate data-structures: task_struct::perf_event_ctxp -> perf_event_context <- perf_cpu_context ^ | ^ ^ `---------------------------' | | | | perf_cpu_pmu_context <--. | `----. ^ | | | | | | v v | | ,--> perf_event_pmu_context | | | | | | | v v | perf_event ---> pmu ----------------' [ See commit bd27568117 for more details. ] This rewrite was developed by Peter Zijlstra and Ravi Bangoria. - Optimize perf_tp_event() - Update the Intel uncore PMU driver, extending it with UPI topology discovery on various hardware models. - Misc fixes & cleanups Signed-off-by: Ingo Molnar <mingo@kernel.org> -----BEGIN PGP SIGNATURE----- iQJFBAABCgAvFiEEBpT5eoXrXCwVQwEKEnMQ0APhK1gFAmOXjuURHG1pbmdvQGtl cm5lbC5vcmcACgkQEnMQ0APhK1j+VhAAknimsLwenTHCGQp7yqsWSKfBr9KI2UgD ZgtQuuwRwSzwqAEwC5Mt6zcIkxRNhU1ookFPqQbpY3XA0W4aNakUk8bDF8QIEKW0 MFWxn7PtReWqKcUay2oEGGurqZ5OtfpljJGxigQh5oVeMGc+itIwHF2JefeyoRnu pq7R2qDgOBb7Np4lWTdqXGmKufzp04/nely2IZQBO8x80cGRZiKQIrGrch6vLUf7 3iEz9rwmvPyz0aczYSpa/duEZDMLm4lWNK4oMUEXuUWC8gU7CUzBJsJ3AS5NgxAu yGBXe/s7GHqwtc/F30l5gK/J5WAyK83IF7sckxTj0dBUpyC6wQwwYPm8BaCAMoqN X6mU7Ve938Siih1TyOBZfZsrtDDILhV2N/nku2erb3iqes26u0RcT25rWtu9Yqvn hm4Gm6cmkHWq4EOHSBvAdC7l7lDZ3fyVI5+8nN9ly9Qv867HjG70dvIr9iEEolpX rhFAz8r/NwTXhDY0AmFZcOkrnNV3IuHtibJ/9wJlgJNqDPqN12Wxqdzy0Nj3HH6G EsukBO05cWaDS0gB8MpaO6Q6YtqAr87ZY+afHDBwcfkME50/CyBLr5rd47dTR+Ip B+zreYKcaNHdEMd1A9KULRTTDnEjlXYMwjVVJiPRV0jcmA3dHmM46HN5Ae9NdO6+ R2BAWv9XR6M= =KNaI -----END PGP SIGNATURE----- Merge tag 'perf-core-2022-12-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull perf events updates from Ingo Molnar: - Thoroughly rewrite the data structures that implement perf task context handling, with the goal of fixing various quirks and unfeatures both in already merged, and in upcoming proposed code.
