27us roundtrip is not really state of the art for zero copy IPC, about 1us would be. What is causing this overhead?

Early 70s: Haynes hardcopy with oil stains, "... Reassembly is the reverse procedure thereof."

Reading in reverse is surprisingly hard


I love how the brake lever positioning there makes it look like they're grabbing their crotch the whole way down.

makes me a feel a little bit better that they deigned to show a fall (~1:46mins in).

Usually large companies attract or develop these skills by their scale. I do think there a lot of smaller companies that are underserved in this area, though.

We had one where data, interpreted as address (simple C typo before static analysis was common) fell into an unmapped memory region and the PCI controller stalled trying to get a response, thereby also halting the internal debugging logic and JTAG just stopped forever (PPC603 core). Each time you'd hit the bug, the debugger was thrown off.


London England or London Ontario?


As a native, we natives know which one.

I find Peppa Pig has multiple layers and the stereotypes of the pig parents are actually targeted to entertain the human parents when they join watching.
