Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Medium] RISCV_ISA_SSQOSID unconditionally selects the user-visible menuconfig RISCV_CBQRI, defeating its prompt and violating Kconfig best practices.

riscv: Enable resctrl filesystem for Ssqosid

This commit enables the resctrl filesystem for the RISC-V Ssqosid extension.
It modifies the RISCV_ISA_SSQOSID config to select ARCH_HAS_CPU_RESCTRL and
RISCV_CBQRI.

[Severity: Medium]
Is it intentional to use select on RISCV_CBQRI here?

RISCV_CBQRI appears to be defined as a user-visible menuconfig:

drivers/resctrl/Kconfig:
menuconfig RISCV_CBQRI
	bool "RISC-V CBQRI support"
	depends on RISCV && RISCV_ISA_SSQOSID

Using select on a user-visible symbol forces it on and overrides the prompt,
which can create a confusing configuration experience where the option is
visible but cannot be toggled.

Could this be addressed by either using "depends on" instead of select,
or by making RISCV_CBQRI a hidden symbol without a prompt?
