ahci:nvme remap support and which laptops would not be able to support Debian
Hi all,
Couple of months back, I had read Matthew Garett's blog post
https://mjg59.dreamwidth.org/44694.html
I also remember Ben Hutchings or somebody from the kernel team had
also shared their view on planet.debian.org on the same subject.
I was helping a friend/client to find out a newer thinkpad for
himself. He wants one which comes with SSD.
I remembered the blog post and found it again after a brief search.
This time it tuns out that some patches has been posted -
http://lists.infradead.org/pipermail/linux-nvme/2016-October/006800.html
I looked up nvme and found it to be a fancy name for flash/SSD's which
use PCI Express are prevalent in the market .
https://en.wikipedia.org/wiki/NVM_Express
Now I also looked up the discussions which were there using thread view -
http://lists.infradead.org/pipermail/linux-nvme/2016-October/thread.html
and the discussion kinda got stopped at
http://lists.infradead.org/pipermail/linux-nvme/2016-October/006834.html
At least from the reading of that it seems that those patches will not
go anywhere as it is deemed to be an Intel non-standard
implementation.
In the thinkpad range, if the above is true, then only a few models
which have SSD in-built should be affected -
The X-1 Carbon series

and one of the thinkpad x260 series -
http://shopap.lenovo.com/in/en/laptops/thinkpad/x-series/x260/?IPromoID=LEN602146
The sense I got from reading of the issue is this would affect ONLY
Intel SSD's and not other vendors .
For instance if I were to install
https://www.flipkart.com/sandisk-ultra-ii-512-gb-desktop-laptop-internal-hard-drive-sdmsata-512g-g25/p/itmezpz4g5h55syj?pid=IHDEZPZ4PA6PFESP
on any laptop it shouldn't be an issue as far as booting Debian on it
is concerned as the interface is SATA.
Seems to be an issue only when you have 'Intel' + 'PCI Express' + SSD
then it may be an issue.
Am I correct in reading the situation ?
