** Description changed: + SRU Justification: + ================== + + [Impact] + + * This in a hardware enablement SRU, + + * and adds support for (new) IBM z16 counters + + * to the s390-tools package. + + [Test Plan] + + * Prepare an IBM z16 LPAR with Ubuntu 20.04, 21.10 or 22.04 (incl. this + patch). + + * At LPARs activation profile, navigate to the Security page + and within the counter facility options, select each counter set you want to use. + (One may just select all for testing purposes.) + + * Use 'perf list' to determine if the new counters are listed. + For comparing the new counters see: + https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git\ + /commit/?id=c9311de71635d3eaa158df8516b9b99a92d60a0c + + * Use 'perf stat -e' to enable and make use of these counters. + + [Where problems could occur] + + * The machine type, model or name could be mixed up, + which may lead to wrong counters for the machines identified. + + * Initialization of the new struct cpumcf_z16_counters could be wrong. + + * The hex code for the counters could be wrong or mixed up, + or the names might be wrong or mixed up, + in which case one will get wrong or unexpected results. + + * The expansion of the case statement to determine the correct (z16) hardware + might be wrong, which would lead to potentially counters, + that may not match to the underlying hardware. + + * The new code may have syntactical errors, + which would become visible during a test compile. + + * Only new code is added by this commit - none is changed nor removed. + + [Other Info] + + * The new IBM z16 was announced after jammy feature freeze, + hence the name and details need to be added now, after the 22.04 release. + __________ + Add new CPU-MF Counters for new IBM Z Hardware - s390-tools part Description: Add new CPU-MF Counters for new IBM Z Hardware. Has a kernel, s390utils/s390-tools and libpfm part. Request Type: Package - Update Version Upstream Acceptance: In Progress
