** Description changed: - intel-speed-select can hep sysadmin on various cpu perf/freq related - decission. Adding this to linux-tool would be very useful. + SRU Justification: + + [Impact] + + The intel-speed-select utility provides more granular control and + inspection capabilities for Intel CPUs with Intel Speed Select + Technology (SST) support. This utility is built from Linux kernel + sources. + + [Fix] + + Apply the patch "UBUNTU: [Packaging] Add intel-speed-select to + linux-tools" from Resolute that builds and packages the + intel-speed-select binary in a binary packaged named + $(SRCPKG)-tools-$(ABIVER) under /usr/lib/$(SRCPKG)-tools-$(ABIVER). This + applies only to Ubuntu kernel builds where do_tools_x86 is true. + + This patch is to be applied to Questing and Noble. It is a clean cherry + pick to Questing, and a backport to Noble. It is already present in + Resolute and newer. + + [Test Plan] + + 1. Build the generic kernel with this patch applied. + + 2. Verify the only additional file is the intel-speed-select utility: + + $ debdiff linux-tools-6.17.0-29.29_6.17.0-29.29_amd64.deb linux- + tools-6.17.0-1029.29_6.17.0-1029.29_amd64.deb + + 3. Run intel-speed-select, verify the output is as expected. + + $ sudo /usr/lib/linux-tools-6.17.0-1030/intel-speed-select turbo-freq info -l 0 + Intel(R) Speed Select Technology + Executing on CPU model:173[0xad] + Caching topology information + package-0 + die-0 + powerdomain-0 + cpu-0 + speed-select-turbo-freq-properties + bucket-0 + high-priority-cores-count:24 + high-priority-max-level-0-frequency(MHz):3900 + high-priority-max-level-1-frequency(MHz):3900 + ... + + [Where problems could occur] + + Any possible issues would likely affect the kernel tools packaging. The + risk of regression is low, as this patch only adds a single binary to + the $(SRCPKG)-tools-$(ABIVER) binary package. No wrapper scripts are + added or modified. + + + intel-speed-select can hep sysadmin on various cpu perf/freq related decission. Adding this to linux-tool would be very useful. https://docs.kernel.org/admin-guide/pm/intel-speed-select.html
