maintenance aside from ports
-
Maintaining Linux 3.2.y stable update series on
kernel.org
Linux releases early and often
-
Linux is released about 5 times a year (plus stable updates
every week or two)
-
...though some features aren't ready to use when they firat
appear in a release
-
Since my talk last year, Linus has made 6 releases (3.11-3.16)
-
Good news: we have lots of new kernel features in testing/unstable
-
Bad news: some of them won't really work without new userland
Recap of last year's features (1)
-
Team device driver: userland package (libteam) was uploaded in
October
-
Transcendent memory: frontswap, zswap and Xen tmem will be
enabled in next kernel upload
-
New KMS drivers: should all work with current Xorg drivers
-
Module signing: still not enabled, but probably will be if we
do Secure Boot
Recap of last year's features (2)
-
More support for discard: still not enabled at install time
(#690977)
-
More support for containers: XFS was fixed, and user namespaces
have been enabled
-
bcache: userland package (bcache-tools) still not quite ready
(#708132)
-
ARMv7 multiplatform: d-i works on some platforms but
I'm still not sure which. Some progress on GPU drivers, but not
in Debian yet.
Questions?
