Hi Jeff,
".....Is your hardware documentation public? I can help provide a sample
driver for your hardware, or help guide your engineers in this
effort........"
=>>>>> Product spec is under preparation, will be provided soon.
Right after doc public, please help us to provide a sample driver in your
eralier conveniance??
This way to ensure SATA driver of this hardware will be compliance with
Linux kernel requirement.
Thanks!
James Hsu

We would be glad to help!
This driver is an ATA driver, which duplicates the existing SCSI<->ATA
translation code we already have. It also fails to work around the
problems ("quirks") found in a large number of ATA devices.
As such, it would be preferred that this ATA hardware use the existing
ATA driver API.
You can see example drivers for advanced controllers such a
drivers/ata/ahci.c and drivers/ata/sata_sil24.c, which are both
FIS-based controllers with full NCQ support, hotplug support, port
multiplier support, and many others.
It is important in Linux that we do not duplicate effort by merging
drivers that duplicate the existing SCSI<->ATA translation layer, or
fail to use our existing ATA API.
Overall, we wish to avoid adding another ATA driver inside the SCSI
layer, without using the existing ATA<->SCSI code.
Is your hardware documentation public? I can help provide a sample
driver for your hardware, or help guide your engineers in this effort.
Regards,
Jeff, the Linux ATA maintainer
