  "message": "cpu: add support for detecting RISC-V extensions\n\nAdd a RISCV64 variable to cpu that indicates both the presence\nof RISC-V extensions and performance information about the underlying\nRISC-V cores.  The variable is only populated with non false values on\nLinux.  The detection code first attempts to use the riscv_hwprobe\nsyscall introduced in Linux 6.4, falling back to HWCAP if riscv_hwprobe\nis not supported.  The patch can detect the C, V, Zba, Zbb and Zbs\nextensions.  V, Zba, Zbb and Zbs can only be detected on a 6.5 kernel\nor later (without backports).\n\nUpdates golang/go#61416\n\nChange-Id: I40f92724ee3d337c06bdc559ff0b18a8f6bfda9f\nReviewed-on: https://go-review.googlesource.com/c/sys/+/605815\nReviewed-by: Cherry Mui \u003ccherryyz@google.com\u003e\nReviewed-by: Dmitri Shuralyov \u003cdmitshur@google.com\u003e\nLUCI-TryBot-Result: Go LUCI \u003cgolang-scoped@luci-project-accounts.iam.gserviceaccount.com\u003e\nReviewed-by: Joel Sing \u003cjoel@sing.id.au\u003e\nReviewed-by: Meng Zhuo \u003cmengzhuo1203@gmail.com\u003e\n",
