CONFIG_ERRATA_MIPS_P8700_PAUSE_OPCODE: Fix the PAUSE Opcode for MIPS P8700

General informations

The Linux kernel configuration item CONFIG_ERRATA_MIPS_P8700_PAUSE_OPCODE:

• prompt: Fix the PAUSE Opcode for MIPS P8700
• type: bool
• depends on: CONFIG_ERRATA_MIPS && CONFIG_64BIT
• defined in arch/riscv/Kconfig.errata
• found in Linux kernels: 6.18-rc+HEAD

Help text

The RISCV MIPS P8700 uses a different opcode for PAUSE. It is a 'hint' encoding of the SLLI instruction, with rd=0, rs1=0 and imm=5. It will behave as a NOP instruction if no additional behavior beyond that of SLLI is implemented.

If you are not using the P8700 processor, say n.
