Sorry, there are remaining issues to resolve before enabling ADMA by
default.
Sorry, this is NOT ADMA. SWNCQ is completely independent from ADMA.
Heh, right. Sorry about that. I disabled ADMA on the distro I work for
and somehow ADMA was disabled on mainline too. :-)
Robert, is SWNCQ safe to turn on by default? I personally think it's
better to prefer safety over performance or optional features and given
the history of NCQ support on nv satas, I feel a bit more cautious.
Maybe we can enable SWNCQ on -mm and devel branches and disable it late
in release cycle for 2.6.26 for a trial?
I haven't seen any problem reports, but with it disabled by default most
people haven't tried it. The only way to really know is to try turning
it on by default and see what shakes out.
I'd vote to enable it by default in -mm and 2.6.26-rc and see what happens.
