CONFIG_MIPS_MT_SMP: MIPS MT SMP support (1 TC on each available VPE)

General informations

The Linux kernel configuration item CONFIG_MIPS_MT_SMP has multiple definitions:

MIPS MT SMP support (1 TC on each available VPE) found in arch/mips/Kconfig

The configuration item CONFIG_MIPS_MT_SMP:

• prompt: MIPS MT SMP support (1 TC on each available VPE)
• type: bool
• depends on: ( CONFIG_TARGET_ISA_REV > CONFIG_0 && CONFIG_TARGET_ISA_REV < CONFIG_6 ) && ( CONFIG_SYS_SUPPORTS_MULTITHREADING && ! CONFIG_CPU_MICROMIPS )
• defined in arch/mips/Kconfig
• found in Linux kernels: 3.16–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.17, 6.18-rc+HEAD

Help text

This is a kernel model which is known as SMVP. This is supported on cores with the MT ASE and uses the available VPEs to implement virtual processors which supports SMP. This is equivalent to the Intel Hyperthreading feature. For further information go to http://www.imgtec.com/mips/mips-multithreading.asp.
