Subject: Question about driver category for submission
Date: Tue, 5 May 2015 13:00:54 -0400 (EDT) [thread overview]
Message-ID: <1430845254.106831601@apps.rackspace.com> (raw)
Hello,
We would like to submit our driver for Linux kernel embedded. Our product is using Marvell 9480/9495 SAS/SATA controller with Marvell Port Multiplier(PM) controller to provide PM feature for SATA HDDs. From driver source package, we found the Marvell has provided “mvsas” source package that covers this chip. But here are questions
1. The “mvsas” is based on SCSI modules so it links to scsi library where it doesn’t support PM feature
2. We use the same controller chip, so we can’t have the code in other category.
3. To use PM feature, we need to link to SATA library
Our current code is proprietary which uses scsi module and add PM and staggered drive spin up features. Hence, this question is to ask Linux community to tell us how should we proceed this if we want to open our code and get driver embedded? Do we need to add our code based on mvsas source? How do we include SATA library in scsi module? or other alternatives?
Best Regards,
HighPoint Linux Team
