36 bool "Enable removal of RAM from kernel mappings for tracing"
37 depends on PPC_POWERNV && MEMORY_HOTREMOVE
40 Enabling this option allows for the removal of memory (RAM)
41 from the kernel mappings to be used for hardware tracing.
44 bool "IBM Virtual Accelerator Switchboard (VAS)"
45 depends on PPC_POWERNV && PPC_64K_PAGES
48 This enables support for IBM Virtual Accelerator Switchboard (VAS).
50 VAS allows accelerators in co-processors like NX-GZIP and NX-842
51 to be accessible to kernel subsystems and user processes.
53 VAS adapters are found in POWER9 based systems.
