Re: Oracle kernel patches for SPARC S7 IB support

Thanks Adrian, we appreciate your assistance, a new test kernel will be great!
Regarding IB patches, it will be helpful to have more details (meaningful issue descriptions) regarding Orabugs 23055865 and 23055807.  Many of us don't have Oracle MOS/BUGS related access. What exactly do the following Infiniband patches resolve? 

https://github.com/oracle/linux-uek/commit/fc779be69835f2ce95b767faab4a5f6ba578a04f

https://github.com/oracle/linux-uek/commit/2e3c491ee5973fee0cad79c7c807a2695f0b154d
It may be helpful to have web links, so we can easily see diffs and issue descriptions for all Debian related patches used in the sparc64 kernel.   At this point, unsure how many Debian sparc64 patches in total and what they fix?
On another note, will there be an updated ISO image with new kernel fixes within ports in the near future?  Unsure what steps are involved before all this work actually turns into an updated ISO release for everyone?   Curious regarding the process of going from one stage to the next, since the latest sparc64 ports ISO is from May 2023.  I am new regarding understanding the Debian release process.
