Asus P9A-I / Marvell 88SE9485 / Apply kernel patch

[Andreas Piening]

Hi there,
I installed Proxmox 4.4 on a Asus P9A-I based system and noticed that the drives on the SATA-Controller was not showing up. The controller is a "RAID bus controller: Marvell Technology Group Ltd. 88SE9485 SAS/SATA 6Gb/s controller (rev c3)" as lspci told me.
After a bit of research I found that this controller is supported by the "mvsas" driver, but the device ID of this particular controller is not added to the list of supported devices. The module simply does not initialize the device.
There is a kernel patch at x://bugs.launchpad.net/ubuntu/+source/linux/+bug/1270844 which basically adds the device id to the mvsas module code so that it is aware of this controller type (see here x://marc.info/?l=linux-scsi&m=146005515401214).

Long story short: I need to download the kernel source, patch the mvsas module source and recompile the modules to get a version of mvsas which supports my controller.
I saw that I can get the kernel headers of the PVE kernel with "aptitude install pve-headers-`uname -r`" but I need the full source of the PVE kernel to be able to do this.
So where can I get the full source?

Kind regards

Andreas

I replaced http with x in my thread, since the URLs are needed to clarify what patch I'm talking about.
Sorry for that, I really don't want to spam or advertise anything.

you'd need to file an SRU bug over at launchpad for cherry-picking commit 7517b26c65eb4866ec9a02e9cc2b416c94326313 from linux-stable (it has been included in 4.7, so chances are that the Ubuntu kernel team will backport it).

you can get our sources and build scripts from here: https://git.proxmox.com/?p=pve-kernel.git;a=tree;h=refs/heads/stable-4;hb=refs/heads/stable-4
