Yes. Moreover, because the interrupt count will be incremented, it will not
be possible to re-enter bottom-half processing from that interrupt.
So bottom-half processing is sort of like a ``virtual thread'' without having
a thread.

You should mark NET_BH whenever your driver runs out of *transmit* work to do.
This will cause the higher layer code to kick down more packets to you
and possibly other drivers.
>If so, does it mean that to empty the drive queue the only way to do it is

No. The reason netif_rx marks NET_BH is for some reason unrelated to your
driver. It's been a while, so I don't remember the exact reason, but I think
that it may be done in order to kick-start the processing of the global receive
queue. That is somewhat outside of the scope of concern of the network driver
writer.
The part in your driver where you have to worry about NET_BH is all the cases
where you may run out of transmit work.

EROS - recently mentioned in
Kernel-Traffic
(http://renta.net/org/opensrc/kt/www/kt19990701_25.html#4)
The concept sounds really
promisful, and maybe some of the
ideas should be
integrated already in linux.
Especially the fsck-story
(http://www.eros-os.org/project/novelty.html)
gives me some points.
Would'nt it be good to make the
filesystem persistent in the sense
of
EROS, implementing the something
like the mentionend checkpoint
mechanism?
After a powerfail, the fsck would
know exactly which directory to
check and
repair and would not have to test
the entire drive.
Making anything persistent is sure
much more work,
and will result in rewrite almost
anything.
AFAIK, the problem of hardware
persistency is'nt solved too in
EROS so far.

Hmm...
We are working on a project that has targets for Windoze NT, Linux, AIX, =
HPUX, SGI, and Solaris that must support multiple native locales, =
well... at least Japan (SJIS) and US/English.
We are currently using KAI with its OEM'd Standard C++ Library (Modena I =
think) for all the Unix platforms we support and MSVC++ with its OEM'd =
Standard C++ Library, DinkumWare, for Windows NT/2000. Support the =
various 14882-1998, locale, and system support between the various =
compiler versions and platforms has been more of a nightmare than, IMHO, =
it should be.
I'm particularly having a hard time with KAI, or at least with its =
Standard C++ Libraries. Apparently, while it does support the ANSI-C =
notion of wchar_t, it has no support for the STDCPP wchar_t classes such =
as the all-important std::char_traits<wchar_t>, wstring, wiostream, etc. =
As if this weren't enough, on almost all platforms KAI supports it =
apparently has no support for mbstate_t. Finally, it seems that the only =
locale that any facet are implemented for is the "classic" locale, or =
"C" locale. Even some of those seem to be broken, basically, =
std::get_facet() doesn't work.
I'd like some input regarding the following options:
A) Use a single version of a single Vendors Standard C++ Library on =
every Platform including Windows NT. Unfortunately, what is offered by =
many companies (such as Rogue-Wave and ObjectSpace) is more like the =
Standard Template Library than the Standard C++ Library.
B) Find a standard C++ library that has *complete* 14882-1998 =
support, or at least as complete as Plaguers Dinkumware Standard C++ =
Library that will work with all the platforms KAI supports, specifically =
HPUX, Redhat, SGI, AIX, and Solaris/Intel.
C) Or, if there is no other choice, replace KAI with a compiler that =
has OEM'd runtimes that do have 14882-1998 compliance sufficient enough =
to create standardized international, multiplatform C++ programs.
I am totally open to choices like GNU/OSF but using these for commercial =
projects is very new to me. The last I looked, the GNU C++ libraries =
didn't look like the 14882-1998 standard libraries, especially regarding =
NTMBS, NTWCS, locales, and facets. However, I would love to support =

Get the latest source for the Tulip chipset cards at Donald Becker's

Take the C source file "tulip.c" you've just downloaded and put it into
the kernel directory tree. Assuming you've installed your kernel sources
in the typical location, put "tulip.c" in /usr/src/linux/drivers/net.
Now rebuild the kernel.

there is a correlation, but it is not absolute. there is plenty of
snow and ice in the mountains of ecuador. in other words, your backup
maybe a different level, in which case it may not boot at all.

It's been longer than that, IIRC. It's allegedly more useful to turn gold
into lead, because it's apparently hard to get isotopically pure lead other
ways.
[note all the weasel words, this is from my memories of the collection of old
"Scientific American"s I had when I was a teenager in the '70s. If IDRC I
wouldn't be surprised. The point is that turning lead into gold isn't cost

nod. C++ isn't as mature as it could be. multiple-platform support
might be difficult. depending upon your application, perhaps you
would be better served by choosing a completely different language
such as smalltalk or common-lisp.

Well, it is funny to read this. It is not the point whether you're using
emacs like an editor or like an IDE. Remember the I stands for
integrated, that means you have an editor, a class browser, an event
browser, a debugger and oh yes an executing shell. And a lot more which
eases your daily developing work. All with graphical enhancements
because pictures or images are much more easier to grap.
IDE is more than an editor with included debugging aids. Why is M$ so
popular with their Visual C++ or Borland's CBuilder? I'll leave that
question open.
