[24.04 LTS]: megaraid_sas driver update

[Chandrakanth Patil]

This update has been initiated to incorporate the megaraid_sas driver from upstream into the upcoming Ubuntu 24.04 LTS release.

Assuming the 24.04 already included the patches up to driver version 07.725.01.00-rc1. So, below are the commit IDs after it.

Hi Jeff and Roxana,

These bugs are critical for us, and I don't see any update here. I would like to know where are we on this. will these patches be included in this point kernel?

[Jeff Lane  (bladernr)]

24.04 only recently rolled the kernel tree to 6.7, and we are planning on 6.8. Where are these upstream currently? If they are in 6.8 there is nothing to do here until we roll the kernel tree to 6.8 later this cycle.

Can you tell me which mainline version these exist in currently?

[Jeff Lane  (bladernr)]

Additionally, this says 24.04... is that the correct target? Your email to me says otherwise.

[Chandrakanth Patil (cpatubuntu)]

Hi Jeff,

These patches are available in the 6.7 mainline kernel. does it mean the patches are already included?

[Chandrakanth Patil (cpatubuntu)]

Hi Jeff,

We have created one more BZ for similar patches for our other storage controller (mpt3sas). Which are very important. So Could you please look into it.
Below is the BZ link:

If those patches are all in 6.7 mainline, then yes, they are already included for 24.04. There is a 6.7 kernel in noble-proposed for 24.04 that could technically be installed now.

And thanks for the new bug. We added that to the stuff to work on this next cycle (The next two weeks)

I have verified that all of the patches listed in the description are indeed in the currently 6.8 proposed kernel and should be in 24.04.

$ git describe --tags
Ubuntu-6.8.0-11.11-1-g04cdb2da2df3

[Jeff Lane  (bladernr)]

Marking Fix Committed as these are all in our 6.8 tree and will land in 24.04, there's nothing more to do here but track it for release.
