IONIC_DV_PD_GET_UDMA_MASK(3)                         Ionic Programmer's Manual

NAME
       ionic_dv_pd_get_udma_mask - Get UDMA pipeline mask of a protection
       domain

SYNOPSIS
              #include <infiniband/ionic_dv.h>

              uint8_t ionic_dv_pd_get_udma_mask(struct ibv_pd *ibpd);

DESCRIPTION
       ionic_dv_pd_get_udma_mask() returns the current UDMA pipeline mask
       associated with the protection domain or parent domain ibpd.

       The returned mask indicates which UDMA pipelines are enabled for queues
       created under this protection domain.  It may have been set by a prior
       call to ionic_dv_pd_set_udma_mask(3), or it may be the default mask
       inherited from the device context.

ARGUMENTS
       ibpd   The protection domain or parent domain to query.  Must be an
              ionic protection domain.

RETURN VALUE
       Returns the UDMA pipeline mask of the protection domain.  Returns 0 if
       ibpd is not an ionic protection domain.
