A likely more effective method of at least confirming whether there is |
13 |
such a thing, if you don't already know where it is, would be to |
14 |
view/pager/edit the .config file, since that puts it in flat format, |
15 |
meaning you just have to go down the list, rather than browsing thru all |
16 |
that nesting... |

Of course, grepping for "hypertransport" (case insensitive) might be even |
19 |
more useful, and quicker. Quickly opening a konsole to /usr/src/linux, |
20 |
firing up mc, and doing a search on the term in question, yields a |
21 |
surprising number of hits (this hypertransport in the kernel stuff is new |
22 |
info to me as well). Hypertransport is as I mentioned an AMD connection |
23 |
technology, but they've created a more or less open standard out of it, |
24 |
and apparently, a decent enough number of MIPS and PPC hardware platforms |
25 |
use it, that there is support in the Linux kernel on those platforms for |
26 |
it. From the quick search I just did, it appears the kernel DOES have a |
27 |
CONFIG_HYPERTRANSPORT option, but it only appears on MIPS, as a sub-option |
28 |
dependent on the Yosemite chipset/platform/whatever-it-may-be. Apparently |
29 |
on x86/x86_64/ppc hypertransport itself isn't an option, but something |
30 |
that you either have or don't have, based on the characteristics of the |
31 |
chipset drivers chosen. |
32 |
|
33 |
Quite interesting, I must say. I had known AMD had opened the standard |
34 |
and tried to make it a public one, but wasn't aware that some ppc and mips |
35 |
platforms had incorporated it, so I'm learning something new in all this, |
36 |
myself! |
37 |
|
38 |
That's actually one of the reasons I so enjoy newsgroups and lists such as |
39 |
this -- I never know when a question will come up that'll twist my |
40 |
inquisitiveness of into areas I would have never explored on my own, and |
41 |
I'll learn something either directly from the post content, or from my own |
42 |
exploration stimulated by the content of the post. Those unexpected |
43 |
"ah-ha!" moments, as the new idea clicks into place, filling an |
44 |
information void I didn't know existed, are something I crave, in large |
45 |
part /because/ they are sourced outside of myself, therefore something I |
46 |
wouldn't ordinarily stumble across in my own semi-structured meanderings |
47 |
in search of information. |
48 |
|
49 |
So very cool, you guys stimulated me to learn something I would have |
50 |
missed on my own, today! =8^) |
