Graphing how terribly behind you are on processing patchwork patches may not be good for morale ... oof. Still, managed to get it below 600 for the first time in a long while! #maintainerlyf

Now we just need to persuade +Jonathan Corbetโ€‹ to read them ๐Ÿ˜‰
+Michael Ellerman put another nice summary in his pull request for the v4.8 merge window. Despite the SHA1 for the merge commit starting with 'bad', there is good stuff in there. Loads more POWER9 support in this release including PCI host bridge support, IRQ server support, cpuidle driver, PMU/perf driver, large decrementer and load monitored support.

Interesting article on server design from Facebook. In particular the fact that they went with single chips to remove "the NUMA problem" and this observation (assertion?) on single threaded performance:

"Dropping the TDP below 65W dropped the performance per CPU to unacceptable levels. This is one of the reasons why Atom-class processors have not gained a foothold in large-scale distributed workloads."
