NAME
       dma32_pool_size	-  the	amount of memory to reserve for the 32-bit DMA
       pool

VALUES
   Minimum
   Maximum
   Default
       Specify an integer value.

DESCRIPTION
       This tunable specifies the amount of memory in the  first  4GB  of  the
       physical	 address  space	 to be reserved for DMA for 32-bit cards.  The
       memory is set aside at boot time and cannot be used for other purposes.
       This  is	 required  only on some Itanium platforms.  On platforms where
       the 32-bit pool is not needed, this value is ignored.

       The value of this tunable should be set based on the number  of	32-bit
       cards in the system and the type of cards.

WARNINGS
       All HP-UX kernel tunable parameters are release specific.  This parame‐
       ter may be removed or have its meaning changed in  future  releases  of
       HP-UX.

       Installation of optional kernel software, from HP or other vendors, may
       cause changes to tunable parameter values.   After  installation,  some
       tunable	parameters may no longer be at the default or recommended val‐
       ues.  For information about the effects of installation on tunable val‐
       ues, consult the documentation for the kernel software being installed.
