20:36 <jkridner> anyone know a good place to ask why M.2 has 2x PCIe (single lane), instead of 1x PCIe (dual lane)? It seems to me it makes things more complex while lowering the maximum throughput.

20:37 <jkridner> (unless you really are controlling 2 things completely independently).

22:22 <zmatt> well depends on the socket/key

22:22 <zmatt> though it's a good question why *any* configuration has 2x PCIe x1

22:24 <zmatt> (and does anything actually use it?)

22:31 <zmatt> jkridner: it can be either: "Socket 1 pinout has provision for an additional PCI Express lane indicated by the suffix 1 to the signal names. These additional PETx1 and PERx1 signal sets can serve as the second Lane to the original PCI Express interface, or alternatively, they can be complimented with a second set of REFCLKx1 and a set of Auxiliary Signals on the adjacent Reserved pins to form a ...

22:31 <zmatt> ...complete second PCI Express x1 interface."

22:31 <zmatt> -- PCI Express M.2 Specification 1.0

22:36 <zmatt> "The PCI Express interface supported in Socket 2 is a two Lane interface"

22:38 <zmatt> and Socket 3 is 1x PCIe x4

22:40 <zmatt> jkridner: the second PCIe interface option really seems more like a "reserved / for future use" thing, at least in the M.2 1.0 spec... the only reason I can think of to have one would be in case the M.2 module has two PCIe device on it, to avoid having to add a PCIe bridge to the module

22:42 <zmatt> M.2 is kind of a mess

23:23 <set_> Well, three months down the road and BAM! CANL and CANH!

23:23 <set_> It just arrived. That took a long time.

23:23 <set_> Now, I can follow along and do some stuff.

23:25 <set_> Make my car go sideways?

23:25 <set_> Ha.

23:26 <set_> Oh! I forgot...

23:26 <set_> Does me having an irregular heap size account for a program being either too small or too large for the BBBW?

23:28 <set_> Well, I ask b/c I run this source on a 64-bit 'puter and "dandy." But...I run it on the arm, 32-bit BBBW and I get heap errors.

23:28 <set_> My java issue just shuts down the program.

23:31 <set_> Anyway, I will ask in the forum to see if anyone is using java for music w/ jython, i.e. whom also has followed along in this particular book.

23:32 <set_> Old, old, old book.

23:58 <set_> I guess tracking down the heap error somehow is the cure. Hmm. Do you think that priorityQueue in the java is the route to take or should I test something on the BBBW to find this specific output?
