Hi, thanks for publishing this.
Add the Software NCQ support to sata_nv.c for MCP51/MCP55/MCP61 SATA controller. This patch base on sata_nv.c file from kernel 2.6.22-rc1 See attachment for the patch. Signed-off-by: Kuan Luo <[EMAIL PROTECTED]> Signed-off-by: Peer Chen <[EMAIL PROTECTED]> ================================== See attached file. ==================================
However, I saw this in the patch: + /* determine if physical DMA addr spans 64K boundary. + * Note h/w doesn't support 64-bit, so we unconditionally + * truncate dma_addr_t to u32. + */ + addr = (u32) sg_dma_address(sg); Does it mean that I can't upgrade my machine to 4 GB or more without losing NCQ or risking data corruption? Can the code be made IOMMU-aware?
