Cable detection on NV PATA hosts isn't implemented and the CBLID- cable isn't wired according to the sepc either, so both host-side and generic drive-side cable detections are broken. Till now, nv_cable_detect() relied on peeking BIOS and ACPI configurations to upgrade to 80C but this often results in misdetection of 40C cable as 80C. Also, the original implementation was broken in that by the time BIOS configuration is read it has already been cleared by programming PIO0 during reset. This patch reimplements NV mode selection such that... * BIOS configuration value is stored during driver attach and restored on detach. * Cable type is fixed to ATA_CBL_PATA_IGN and mode selection is soley done by nv_mode_filter() which peeks both BIOS and ACPI configurations and filter accordingly.

Yeah, I think this is a better way to do things long term. Thanks... - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
