Bug 325805 – [PATCH] MegaRAID SAS 8208ELP kernel support

• Product: Gentoo Linux
• Status: RESOLVED LATER

[Description Akkara 2010-06-27 06:40:49 UTC]

I was setting up a machine which has a MegaRAID SAS 8208ELP SATA/SAS raid controller.  The stock gentoo-sources-2.6.34-r1 did not seem to recognize this chip.

I found a patch [1] which enables support for the chipset in the kernel.  After applying this patch, the raid controller was recognized and seems to work.  I've only tested one hard-drive in the bay so far, but it is recognized, mounts and checksum verifies on the existing files, and hot-swap works.  A cursory test of suspend-to-ram suggests that works, too.

It seems next logical step is inclusion of this patch in gentoo-sources.  Hence this bug.

ebuild that applies patch to gentoo-sources-2.6.34-r1

patch has been rejected repeatedly by eric moore for inclusion in the kernel, since device id 0x59 is in use by megasr (megaraid driver) which is not included in the kernel. megasr supports "hardware" raid arrays created within controller bios, but no direct access to sata drives.

We ( as kernel team ) don't accept patches outside the Linux kernel tree. I will leave this bug open just for reference

[Comment 6 Mike Pagano 2010-07-08 00:06:56 UTC]

Let us know if this or a similar patch gets accepted into the upstream kernel tree
