- * Starting on Power9 systems, DMA addresses for NVLink are no longer
- * the same as used over PCIe.
- *
- * Power9 supports a 56-bit Real Address. This address range is compressed
- * when accessed over NVLink to allow the GPU to access all of memory using
- * its 47-bit Physical address.
- *
- * If there is an NPU device present on the system, it implies that NVLink
- * sysmem links are present and we need to apply the required address
- * conversion for NVLink within the driver.
- *
- * See Bug 1920398 for further background and details.
- *
- * Note, a deviation from the documented compression scheme is that the
- * upper address bits (i.e. bit 56-63) instead of being set to zero are
- * preserved during NVLink address compression so the orignal PCIe DMA
- * address can be reconstructed on expansion. These bits can be safely
- * ignored on NVLink since they are truncated by the GPU.
- *
- * Bug 1968345: As a performance enhancement it is the responsibility of
- * the caller on PowerPC platforms to check for presence of an NPU device
- * before the address transformation is applied.
