.SH NAME
ionic_dv_pd_get_udma_mask \- Get UDMA pipeline mask of a protection
domain
.SH SYNOPSIS
.IP
.EX
#include \f[B]<infiniband/ionic_dv.h>\f[R]

uint8_t ionic_dv_pd_get_udma_mask(\f[B]struct\f[R] ibv_pd *ibpd);
.EE
.SH DESCRIPTION
\f[B]ionic_dv_pd_get_udma_mask()\f[R] returns the current UDMA pipeline
mask associated with the protection domain or parent domain
\f[I]ibpd\f[R].
.PP
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
\f[B]ionic_dv_pd_set_udma_mask\f[R](3), or it may be the default mask
inherited from the device context.
.SH ARGUMENTS
.TP
\f[I]ibpd\f[R]
The protection domain or parent domain to query.
Must be an ionic protection domain.
.SH RETURN VALUE
Returns the UDMA pipeline mask of the protection domain.
Returns 0 if \f[I]ibpd\f[R] is not an ionic protection domain.
