Lines Matching full:iova

31  *  - ENOENT: An ID or IOVA provided does not exist.
71  * Allocate an IO Address Space (IOAS) which holds an IO Virtual Address (IOVA)
83  * @start: First IOVA
84  * @last: Inclusive last IOVA
86  * An interval in IOVA space.
100  * @out_iova_alignment: Minimum alignment required for mapping IOVA
102  * Query an IOAS for ranges of allowed IOVAs. Mapping IOVA outside these ranges
118  * out_iova_alignment returns the minimum IOVA alignment that can be given
119  * to IOMMU_IOAS_MAP/COPY. IOVA's must satisfy::
124  * out_iova_alignment can be 1 indicating any IOVA is allowed. It cannot
146  * succeeds then IOMMU_IOAS_IOVA_RANGES will never return a list of IOVA ranges
151  * devices are attached the IOVA will narrow based on the device restrictions.
155  * Automatic IOVA allocation is also impacted by this call. MAP will only

190  * @iova: IOVA the mapping was placed at. If IOMMU_IOAS_MAP_FIXED_IOVA is set
193  * Set an IOVA mapping from a user pointer. If FIXED_IOVA is specified then the
194  * mapping will be established at iova, otherwise a suitable location based on
196  * iova.
198  * If IOMMU_IOAS_MAP_FIXED_IOVA is specified then the iova range must currently
199  * be unused, existing IOVA cannot be replaced.
