2023-01-03RISC-V: Support CPUID for risc-v in perfJoão Mário Domingos1-0/+18
This patch creates the header.c file for the risc-v architecture and introduces support for PMU identification through sysfs. It is now possible to configure pmu-events in risc-v. Depends on patch [1], that introduces the id sysfs file. Signed-off-by: João Mário Domingos <joao.mario@tecnico.ulisboa.pt> Signed-off-by: minda.chen <minda.chen@starfivetech.com>
2023-01-03RISC-V: Create unique identification for SoC PMUJoão Mário Domingos1-0/+47
The SBI PMU platform driver did not provide any identification for perf events matching. This patch introduces a new sysfs file inside the platform device (soc:pmu/id) for pmu identification. The identification is a 64-bit value generated as: [63-32]: mvendorid; [31]: marchid[MSB]; [30-16]: marchid[15-0]; [15-0]: mimpid[15MSBs]; The CSRs are detailed in the RISC-V privileged spec [1]. The marchid is split in MSB + 15LSBs, due to the MSB being used for open-source architecture identification.

2023-01-03RISC-V: Add sscofpmf extension supportAtish Patra1-5/+217
The sscofpmf extension allows counter overflow and filtering for programmable counters. Enable the perf driver to handle the overflow interrupt. The overflow interrupt is a hart local interrupt. Thus, per cpu overflow interrupts are setup as a child under the root INTC irq domain. Signed-off-by: Atish Patra <atish.patra@wdc.com> Signed-off-by: Atish Patra <atishp@rivosinc.com>
2023-01-03RISC-V: Add perf platform driver based on SBI PMU extensionAtish Patra4-0/+591
RISC-V SBI specification added a PMU extension that allows to configure start/stop any pmu counter. The RISC-V perf can use most of the generic perf features except interrupt overflow and event filtering based on privilege mode which will be added in future. It also allows to monitor a handful of firmware counters that can provide insights into firmware activity during a performance analysis.

2023-01-03RISC-V: Add a simple platform driver for RISC-V legacy perfAtish Patra3-0/+153
The old RISC-V perf implementation allowed counting of only cycle/instruction counters using perf. Restore that feature by implementing a simple platform driver under a separate config to provide backward compatibility. Any existing software stack will continue to work as it is. However, it provides an easy way out in future where we can remove the legacy driver.

Implement a perf core library that can support all the essential perf features in future. It can also accommodate any type of PMU implementation in future. Currently, both SBI based perf driver and legacy driver implemented uses the library. Most of the common perf functionalities are kept in this core library wile PMU specific driver can implement PMU specific features. For example, the SBI specific functionality will be implemented in the SBI specific driver.
