Dear Jeff,
This is Jim,an IC PM from ACARD Technology. Thanks for your effort on
building Linux driver for ACARD ATP8620. Since ACARD already have a
verified AHCI driver for ATP8620, we'd like to submit this one for the
kernel built-in driver (please see attachment). This driver support
Linux Kernel 2.6.29 AHCI mode for ATP8620 (2ch SATA IC) and ATP8624 (4ch
SATA IC). It already passed our own stability and compatibility test
with SATA devices like HDD, ODD, or PortMultiplier. If you have any
question or need the hardware for testing, please don't hesitate to
contact me. Thanks again for your help.
Thank you for your email.
We understand you have verified your driver, but it is standard Linux
driver policy to avoid code duplication. Multiple implementations of
AHCI drivers implies several negative factors:
* each bug fix must be reviewed across multiple AHCI drivers, to
determine if the bug fix must be copied
* non-uniform user experience, depending on AHCI platform
* Shared AHCI code gets much more testing and verification.
* When a hardware vendor's AHCI chip reaches End Of Life, or the company
goes out of business, users are not abandoned.
So, for the official Linux kernel drivers that are shipped by Red Hat,
Novell/SuSE, Canonical and other vendors, we will need to modify the
existing Linux AHCI driver to support ATP8620 and ATP8624.
And yes -- test hardware would be greatly appreciated! If you could
send these, that would be appreciated:
To Tejun Heo
------------
1 x ATP8620
1 x ATP8624
To Jeff Garzik
--------------
1 x ATP8620
1 x ATP8624
I assume this is PCI, PCI-X or PCI-Express form factor?
Regards and thanks,
Jeff
