config CAVIUM_CN63XXP1
	bool "Enable CN63XXP1 errata workarounds"
	default "n"
	help
	  The CN63XXP1 chip requires build time workarounds to
	  function reliably, select this option to enable them.  These
	  workarounds will cause a slight decrease in performance on
	  non-CN63XXP1 hardware, so it is recommended to select "n"
	  unless it is known the workarounds are needed.

	help
	  CVMSEG LM is a segment that accesses portions of the dcache as a
	  local memory; the larger CVMSEG is, the smaller the cache is.
	  This selects the size of CVMSEG LM, which is in cache blocks. The
	  legally range is from zero to 54 cache blocks (i.e. CVMSEG LM is
	  between zero and 6192 bytes).

	help
	  Reserve a shared memory region for user processes to use for hardware
	  memory buffers. This is required for 32bit applications to be able to
	  send and receive packets directly. Applications access this memory by
	  memory mapping /dev/mem for the addresses in /proc/octeon_info. For
	  optimal performance with HugeTLBs, keep this size an even number of
	  megabytes.

	  This driver is a module to measure interrupt latency using the
	  the CIU Timers on Octeon.

To compile this driver as a module, choose M here.  The module
	  will be called octeon-ilm
