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.
