312eca95 - drivers/perf: hisi: Add support for HiSilicon UC PMU driver

Thu, 15 Jun 2023 12:59:25 +0000

drivers/perf: hisi: Add support for HiSilicon UC PMU driverOn HiSilicon Hip09 platform, there are 4 UC (unified cache) moduleson each chip CCL (CPU Cluster). UC is a cache that providescoherence between NUMA and UMA domains. It is located between L2and Memory System. Many PMU events are supported. Let's supportthe UC PMU driver using the HiSilicon uncore PMU framework.* rd_req_en : rd_req_en is the abbreviation of read request tracetagenable and allows user to count only read operations. Details are listedin the hisi-pmu document at Documentation/admin-guide/perf/hisi-pmu.rst* srcid_en & srcid: Allows users to filter statistical information basedon specific CPU/ICL by srcid.srcid_en depends on rd_req_en being enabled.* uring_channel: Allows users to filter statistical information based onthe specified tx request uring channel.uring_channel only supported events: [0x47 ~ 0x59].Signed-off-by: Junhao He Reviewed-by: Yicong Yang Reviewed-by: Jonathan Cameron Acked-by: Mark Rutland Link: https://lore.kernel.org/r/20230615125926.29832-3-hejunhao3@huawei.comSigned-off-by: Will Deacon List of files: /linux-6.15/drivers/perf/hisilicon/Makefile

drivers/perf: hisi: add driver for HNS3 PMUHNS3(HiSilicon Network System 3) PMU is RCiEP device in HiSilicon SoC NIC,supports collection of performance statistics such as bandwidth, latency,packet rate and interrupt rate.NIC of each SICL has one PMU device for it. Driver registers each PMUdevice to perf, and exports information of supported events, filter mode ofeach event, bdf range, hardware clock frequency, identifier and so on viasysfs.Each PMU device has its own registers of control, counters and interrupt,and it supports 8 hardware events, each hardward event has its ownregisters for configuration, counters and interrupt.Filter options contains:config - select eventport - select physical port of nictc - select tc(must be used with port)func - select PF/VFqueue - select queue of PF/VF(must be used with func)intr - select interrupt number(must be used with func)global - select all functions of IO DIESigned-off-by: Guangbin Huang Reviewed-by: John Garry Reviewed-by: Shaokun Zhang Link: https://lore.kernel.org/r/20220628063419.38514-3-huangguangbin2@huawei.comSigned-off-by: Will Deacon List of files: /linux-6.15/drivers/perf/hisilicon/Makefile

drivers/perf: hisi: Add driver for HiSilicon PCIe PMUPCIe PMU Root Complex Integrated End Point(RCiEP) device is supportedto sample bandwidth, latency, buffer occupation etc.Each PMU RCiEP device monitors multiple Root Ports, and each RCiEP isregistered as a PMU in /sys/bus/event_source/devices, so users canselect target PMU, and use filter to do further sets.Filtering options contains:event - select the event.port - select target Root Ports. Information of Root Ports are shown under sysfs.bdf - select requester_id of target EP device.trig_len - set trigger condition for starting event statistics.trig_mode - set trigger mode. 0 means starting to statistic when bigger than trigger condition, and 1 means smaller.thr_len - set threshold for statistics.thr_mode - set threshold mode. 0 means count when bigger than threshold, and 1 means smaller.Acked-by: Krzysztof Wilczyński Reviewed-by: John Garry Signed-off-by: Qi Liu Reviewed-by: Shaokun Zhang Link: https://lore.kernel.org/r/20211202080633.2919-3-liuqi115@huawei.comSigned-off-by: Will Deacon List of files: /linux-6.15/drivers/perf/hisilicon/Makefile

drivers/perf: hisi: Add support for HiSilicon PA PMU driverOn HiSilicon Hip09 platform, there is a PA (Protocol Adapter) module oneach chip SICL (Super I/O Cluster) which incorporates three Hydra interfaceand facilitates the cache coherency between the dies on the chip. While PAuncore PMU model is the same as other Hip09 PMU modules and many PMU eventsare supported. Let's support the PMU driver using the HiSilicon uncore PMUframework.PA PMU supports the following filter functions:* tracetag_en: allows user to count events according to tt_req ortt_core set in L3C PMU. It's the same as other PMUs.* srcid_cmd & srcid_msk: allows user to filter statistics that come fromspecific CCL/ICL by configuration source ID.* tgtid_cmd & tgtid_msk: it is the similar function to srcid_cmd &srcid_msk.
