CONFIG_ERRATA_THEAD_PMU: Apply T-Head PMU errata

General informations

The Linux kernel configuration item CONFIG_ERRATA_THEAD_PMU has multiple definitions:

Apply T-Head PMU errata found in arch/riscv/Kconfig.errata

The configuration item CONFIG_ERRATA_THEAD_PMU:

• prompt: Apply T-Head PMU errata
• type: bool
• depends on: CONFIG_ERRATA_THEAD && CONFIG_RISCV_PMU_SBI
• defined in arch/riscv/Kconfig.errata
• found in Linux kernels: 6.4–6.17, 6.18-rc+HEAD

Help text

The T-Head C9xx cores implement a PMU overflow extension very similar to the core SSCOFPMF extension.

This will apply the overflow errata to handle the non-standard behaviour via the regular SBI PMU driver and interface.

If you don't know what to do here, say "Y".
