dma32_pool_size(5)						File Formats Manual						dma32_pool_size(5)

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.

   Related Parameters
       None

WARNINGS

       All  HP-UX kernel tunable parameters are release specific.  This parameter 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 values.  For information about the effects of installation on tun-
       able values, consult the documentation for the kernel software being installed.	For information about optional kernel  software  that  was
       factory installed on your system, see at
