e51ef8ae490fc9f73191f33e7ad388c2511c454a - hwpmc: Initial support for AMD IBS

Fri, 30 Jan 2026 10:12:17 +0100

hwpmc: Initial support for AMD IBSThis patch adds support for AMD IBS. It adds a new class of performancecounter that cotains two events: ibs-fetch and ibs-op events. Unlikemost existing sampled events, IBS events provide a number of valuescontaining extra information regarding the sample. To support this weuse the existing callchain event, and introduce a new flag for multipartpayloads. The first 8 bytes of the pc_sample contains a header thatdefines up to four payloads.Sponsored by: NetflixReviewed by: imp,mhornePull Request: https://github.com/freebsd/freebsd-src/pull/2022 List of files: /freebsd/sys/modules/hwpmc/Makefile

Wed, 01 Mar 2023 19:32:08 +0100

sys/modules: fix bogus OPT_ACPI testsACPI is not handled specially by sys/conf/kern.opts.mk (unlike a fewoptions), so we should fall back on the generic behavior ofsys/conf/config.mk, which pulls from all the generated opt*.h files,including opt_acpi.h, which will cause DEV_ACPI to be included inKERN_OPTS. Then the generic machinery in sys/conf/kmod.mk will causeSRCS.DEV_ACPI to be included in SRCS when appropriate.Reviewed by: jhb, impSponsored by: MicrosoftDifferential Revision: https://reviews.freebsd.org/D38737 List of files: /freebsd/sys/modules/hwpmc/Makefile

Fix loading the hwpmc module when ACPI is enabledIn 0a9a4d2cd6092 a check for OPT_ACPI was added to the hwpmc Makefileto fix loading the module in a kernel where ACPI has been disabled.This broke loading the module when ACPI was enabled in the build asOPT_ACPI isn't a Makefile macro so was always disabled.Move this check to the C files where the DEV_ACPI macro does exist.Reviewed by: gnnSponsored by: Arm LtdDifferential Revision: https://reviews.freebsd.org/D37773 List of files: /freebsd/sys/modules/hwpmc/Makefile

e92a1350b50edf504316434144bea3566cf8badc - hwpmc: remove unused pre-table driven bits for intel

Fri, 01 Jun 2018 00:41:07 +0200

hwpmc: remove unused pre-table driven bits for intelIntel now provides comprehensive tables for all performance countersand the various valid configuration permutations as text .json files.Libpmc has been converted to use these and hwpmc_core has been greatlysimplified by moving to passthrough of the table values.The one gotcha is that said tables don't support pentium pro and and pentiumIV. There's very few users of hwpmc on _amd64_ kernels on new hardware. It isunlikely that anyone is doing low level optimization on 15 year old Intelhardware. Nonetheless, if someone feels strongly enough to populate thecorresponding tables for p4 and ppro I will reinstate the files in to thebuild.Code for the K8 counters and !x86 architectures remains unchanged.
