[PATCH] sata_nv ADMA/NCQ support for nForce4
This patch adds support for ADMA mode on NVIDIA nForce4 (CK804/MCP04) SATA
controllers to the sata_nv driver. Benefits of ADMA mode include:
- NCQ support
- Reduced CPU overhead (controller DMAs command information from memory
instead of them being pushed in by the CPU)
- Full 64-bit DMA support
ADMA mode is enabled by default in this version. To disable it, set the
module parameter adma_enabled=0.
