44  * free earlier allocated interrupt vectors, and restore INTx emulation.
64  * pci_msix_vec_count() - Get number of MSI-X interrupt vectors on device
67  * Return: number of MSI-X interrupt vectors available on this device
87  * @minvec:  minimum required number of MSI-X vectors
88  * @maxvec:  maximum desired number of MSI-X vectors
100  * Return: number of MSI-X vectors allocated (which might be smaller
101  * than @maxvecs), where Linux IRQ numbers for such allocated vectors
103  * -ENOSPC if less than @minvecs interrupt vectors are available.
187  * free earlier-allocated interrupt vectors, and restore INTx.
207  * pci_alloc_irq_vectors() - Allocate multiple device interrupt vectors
209  * @min_vecs: minimum required number of vectors (must be >= 1)

220  *              the vectors around available CPUs
222  * Allocate up to @max_vecs interrupt vectors on device. MSI-X irq
230  * Return: number of allocated vectors (which might be smaller than
231  * @max_vecs), -ENOSPC if less than @min_vecs interrupt vectors are
244  *                                    vectors with affinity requirements
246  * @min_vecs: minimum required number of vectors (must be >= 1)
