28 tristate 'OPAL PRD driver'
29 depends on PPC_POWERNV
31 This enables the opal-prd driver, a facility to run processor
32 recovery diagnostics on OpenPower machines
35 bool "Enable removal of RAM from kernel mappings for tracing"
36 depends on PPC_POWERNV && MEMORY_HOTREMOVE
39 Enabling this option allows for the removal of memory (RAM)
40 from the kernel mappings to be used for hardware tracing.
43 bool "IBM Virtual Accelerator Switchboard (VAS)"
44 depends on PPC_POWERNV && PPC_64K_PAGES
47 This enables support for IBM Virtual Accelerator Switchboard (VAS).
49 VAS allows accelerators in co-processors like NX-GZIP and NX-842
50 to be accessible to kernel subsystems and user processes.
52 VAS adapters are found in POWER9 based systems.
