Title:
Add hotplug support for Micron's PCIe-SSD devices
Status in The Dell PowerEdge project:
Confirmed
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
Add hotplug (SRSI) support for Micron's PCIe-SSD devices (mtip32xx
driver).
The patches that enable this functionality have been submitted to the
linux-block mailing list:
http://marc.info/?l=linux-kernel&m=136812385512296
Micron has been in direct conversations with Jens Axboe to merge these
patches upstream, as far as I know there are no objections from the
community and should just be a matter of time before they are merged
upstream. They may not land in kernel 3.11, probably looking at 3.12.
I tested these patches with the 3.10.2 kernel and both hot-removal and
hot-insertion work ok. I had to pass the pci=pcie_bus_perf kernel
parameter to avoid MaxPayload issues.
Adding support in Saucy will pave the way for established support in
the 14.04 LTS release.
