"SYNOPSIS"
.sp
\fB
.sp
dma_addr_t tioca_dma_mapped  (struct pci_dev * \fIpdev\fB, uint64_t \fIpaddr\fB, size_t \fIreq_size\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIpdev\fB\fR
linux pci_dev representing the function
.TP
\fB\fIpaddr\fB\fR
host physical address to map
.TP
\fB\fIreq_size\fB\fR
len (bytes) to map
.SH "DESCRIPTION"
.PP
Map \fIpaddr\fR into CA address space using the GART mechanism.  The mapped
dma_addr_t is guarenteed to be contiguous in CA bus space.
