Hi Rainer,

Can you please take this code for FreeBSD 13.0 testing ?

Hi Papani,

unfortunately, I don't have any host with FreeBSD 13 and this HBA currently.

Regards
Rainer

i've staged this commit at
https://github.com/bsdimp/freebsd/tree/D30182
to make sure I've got the details right. This branch builds for me. I have no way to test it, but it's identical here.

Please check to make sure that I've given the proper credit (for author) and the folks that have reviewed it here. I'm unsure if they are co-authors of this or not, but would be happy to credit them as such.
Once this one is sorted out, I'll do the merge using the other review that's going on for 12.2.
This review applies to both stable/13 and to -current as far as I can tell, though I've only test compiled on -current.

OK. This has landed. Please double check me and let me know if I've botched something.... I hope to MFC this in a week or so.

I pulled down the changes you have staged and they look good. I've compiled on 13 and have been running tests on different controllers. Everything's passing so as far as I can tell the changes should be good to go.

Thanks for all of the help.

Excellent. I've just MFC'd this to stable/13. There are some minor CAM API changes coming, what's the best way to ensure that you guys pick them up for your driver?
I'll also MFC to 12 after a couple of days since that's more complex and it gives our processes a chance to build this, get snap-shots out, etc.

Hi,

I have cloned the latest code for FreeBSd 13.0 with below command,

git clone -b releng/13.0 --depth 1 https://git.freebsd.org/src.git src

But i am not finding the above patches in the code.
Can someone help me whether the above patches are merged in 13.0 ?

Thanks & Regards
