"how does QNX handle mmap today with its microkernel arch" and well

> The QNX OS supports POSIX memory locking APls, but only for compatibility reasons. These calls will silently succeed, but in this release all memory is "superlocked",

that's a way to deal with it I guess

QNX 7 is very different

l, ~l
(el) Lock (l) or don't lock (~l) all memory.
NOTE:
In this release, all memory is locked, so these options have no effect.
Locking all memory acts as if mlockall(MCL_CURRENT|MCL_FUTURE) was specified at the start of every program. For more information, see mlockall() in the QNX OS C Library Reference.
L, ~L
Lock and superlock (L) or don't lock and superlock (~L) all memory.
NOTE:
In this release, all memory is locked and superlocked, so these options have no effect.
Locking and superlocking all memory acts as if ThreadCtl( _NTO_TCTL_IO_LEVEL, _NTO_IO_LEVEL_1) was specified at the start of every program (but only insofar as locking the memory; programs don't actually get I/O privileges).

Locking memory

The QNX OS supports POSIX memory locking APls, but only for compatibility reasons. These calls will silently succeed, but in this release all
memory is "superlocked", meaning:
• faulting occurs only when the virtual address isn't mapped or the process doesn't have the necessary access permissions; it always results in a failure of the operation
• all memory must be initialized and privatized, and the permissions set, as soon as the memory is mapped
In this release, the MAP_LAZY flag is sliently ignored and has no effect on mapping behavior.

The text of the post handwritten in Iroshizuku Ku-Jaku and Diamine Quartz Black, with the ink bottles next to the text.

xkcd comic:
Silicate chemistry is second nature to us geochemists, so it's easy to forget that the average person probably only knows the formulas for olivine and one or two feldspars.

And quartz, of course.

Of course.

(Even when they're trying to compensate for it, experts in anything wildly overestimate the average person's familiarity with their field.)

I think a lot about how information about how computers work often seems to get passed down in an "oral history" kind of way

like how “the terminal” works is sort of documented, but it's made of so many components that the documentation is split across a million different documents

and some […]
