Wayland and Weston 1.0 released
The 1.0 release of the Wayland protocol and Weston compositor
implementation has come out right on schedule. "We're entering a
new, exciting and somewhat scary phase for Wayland. As of this 1.0.0
release, we're changing the development model and committing to the the
protocol and client side API we have now." The job is far from
done, but the developers are getting closer to having a credible
replacement for the X Window System. | | 3:00p |
[$] EPOLL_CTL_DISABLE, epoll, and API design In an article last week, we saw that
the EPOLL_CTL_DISABLE operation provides a
way for multithreaded applications that cache information about file
descriptors to safely delete those file descriptors from an epoll interest
list. This week, we revisit the EPOLL_CTL_DISABLE story from a
different angle, with the aim of drawing some lessons about the design of
the APIs that the kernel presents to user space. | | 4:32p |

An Introduction to Full Virtualization With Xen (Linux.com) George Dunlap introduces
a spectrum of virtualization, on Linux.com. " At XenSummit 2012
in San Diego, Mukesh Rathor from Oracle presented his work on a new
virtualization mode, called "PVH". Adding this mode, there are now a rather
dizzying array of different terms thrown about -- "HVM", "PV", "PVHVM",
"PVH" -- what do they all mean? And why do we have so many? The reason we have all these terms is that virtualization is no longer binary; there is a spectrum of virtualization, and the different terms are different points along the spectrum." |
