Subject: Incorrect IRQ mappings by PCI BIOS'es?
Date: Mon, 5 Apr 1999 18:32:29 -0700
Hi All,
I just had a really strange problem when I plugged two different graphics
controllers into my system. Normally when I plug a single controller into
my system, if the PCI device requests an IRQ line it usually gets IRQ 9.
Now this caused me problems in the past in our 32-bit DOS test harness,
because of the funky PC-AT backwards compatibility handling of IRQ 9 by
the system BIOS. For some reason the system boots up with this IRQ
*unmasked*, which means that if I do stuff that causes an IRQ to be
triggered by the card (such as triple buffering) it will lock the system
because no-one is there to handle the IRQ. Under Linux this does not
happen, because Linux is nice about this stuff ;-)
Now to solve the first problem under DOS, I check to see if the IRQ line
is allocated for my controller, and until I need to install an interrupt
handler for it I mask it in the PIC so that it will be ignored.
Now the second problem happens when I plug a second card into my system
(an AGP 2x Intel 440BX PII system with an Award BIOS). For some reason
the PnP BIOS gives the disabled card IRQ 9, but then gives the active
card IRQ 3 which has *already* been alloted to the network controller
(and strangely enough the USB controller)! Since there are now 3 PCI
devices all configured to use the same IRQ, all hell breaks loose.
So I can fix this by re-assigning the IRQ (actually I will probably just
disable it by setting it to 0), but it seemse ridiculous to me that the
BIOS would assign the same IRQ to three separate PCI devices. Not to
mention that USB support would probably barf if the network controller is
already on IRQ 3. I am assuming this is a bug; has anyone else seen this
anomolous behaviour? Does anyone know if the Linux kernel re-assigns
IRQ's at bootup to get around this problem?
Regards,

Do other programs that play audio work under the SMP kernel? (Or, do you
have problems with the above programs if you turn off audio?)
Reason: I had similar problems at one time, which went away once I got
the audio properly configured.

Dare I suggest the 'sysv' fs type? (UFS is generally more of a BSDism).
It's fairly recent; you might need a new kernel, but you can't run linux
and not expect to rebuild the kernel weekly. ;)

The Pentium is running Linux 2.0.35. It turns out the major problem was
that the card was a 3c509, not a 3c509B. Now I have the B card in I
get around 280KB/s but with still a lot of overruns. I expect that I
could improve things by reducing the window size on the P150 but I want
it to also talk fast to other Pentiums. I expect I'll just live with
the 280KB/s on the slow machine.

Sorry, there just isn't any safe way to do this.
Your security is minimally compromised with such a CGI script
if this machine is on a private network. If it is on an internet,
it is a sitting duck. It is generally easier to get root if you
already have a user account. If anyone can give himself a regular
account, well, all bets are off.
Maybe you can use HTTP IDs and mail IDs rather that unix IDs. Most
if not all large IPSs manage mail and dialup accounts without resorting
to unix IDs.
After saying that, if you still insist on anonymous account management,
you can probably find a script. No suggestions there.

Subject: Custom Qt Widgets Repository Release
Date: Tue, 06 Apr 1999 01:14:58 -0500
This is a multi-part message in MIME format.
==============78C1930021C93D937C01CB06
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit
Currently, the website would be http://lindev.jmc.tju.edu/qwor
I am planning to release a Qt Widget repository for custom widgets that are not
part of the baseline product of Qt. I have had a lot of support from the people at
qt-interest mailing list... And i hope that by putting this up, i will also grab a
few other developers of Qt that are not on the list.
I wont be big and complex like freshmeat, or sunsite, but just a nice site where
qt developers can collectively contribute custom widgets (ie: my font dialog box,
someone else's date spin box) in a centralised place.
Below is an outline of the plans... if anyone can help me out as far as
development of custom tools needed for the website... or can suggest some custom
pieces of software that already does this it would be greatly appreciated...
More importantly, however, is my need for a perl cgi that goes against a MySQL
database, very much like freshmeats', or segfaults.
cheers,
elmo
_____________________________________
=========== SITE PLANS ==============
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The repository will be opened this weekend (Apr 9-11) for contributions. I am
compiling a list of repository users if you would like to add something let me
know via personal email.
Currently most of the grunt work will be done manually. However here are some of
the plans within the next two weeks in no particular order:
- Search Engine
- Entry Engine
- Refresh Engine
- Automated CVSWeb Engine
- Reconsideration of WebSite design
+ A software product was suggested by Mike that will automagically go into the
repository and create module listings. CVSWeb (as seen on the KDE site). This will
be incorporated within the next week, probably this weekend.
+ The current site URL will remain the same. However, a nightly backup of the
system will be off loaded to tape.
+ The Search Engine will incorporate LSM files saved to a MySQL database. The
MySQL database is already installed and operational save the actual database for
the storage of the LSM's. The Search Engine will then use dynamic and/or embedded
SQL to retreive data for the developer searching for the widget. This should be
done within the next two weeks barring any serious complications.
+ The Entry Engine, for Module Submissions of 'untrusted' (technical term, not
personal) developers, will be implimented shortly thereafter. The design will
carry out the following model:
1) display a web page (form) with the blank entries for the LSM data.
2) Parse the user's entry for the submission and produce a preview version
(form 1) and an edit version (form 2) on the same page. The user will then be able
to commit the submission of the modules (via form 1) or rollback any changes (via
form 2) and this step will be repeated until the data is commited or the user
cancels the current operation.
3) The user will receive confirmation of their request and be assigned an ID.
The server will then enter the data into a table in the database for "coming soon"
modules, which will update the website accordingly. The CVS administrator will
receive notification (via email) that a submission has been logged and will act
accordingly.
+ Refresh Engine, for the updating of ftp and http data. It will dynamically dig
out any of the LSM files that are in the database; work along side the Search
Engine and CVS Web, to produce an alternate viewable form of data. The model is
similar to the Search Engine, except that it is an alternative to those
individuals who would prefer to: (browse the modules in the repository, modules to
come, or ftp'd widgets) and (view descriptive data found in the LSM database). If
CVS Web can be tailored to do this as well, we can discard this Refresh Engine.
Hence, the reason why it would be last on the list of things to do.
+ Finally, but not least or last, ASAP Website Reconsideration:
As it stands everything is top down, and real basic. Within the next few
days (if
i can tackle calculus III homework 8( within some reasonable amount of time) the
design will change. The new design will look something like this:
HOME -> INTRODUCTION (index.m4)
DOCS ---\
|->CVS DOWNLOAD INFORMATION
|->BASIC WIDGET DOCUMENTATION (using tmake to compile samples
etc...)
|->QWOR PROJECT DOCUMENTATION (ie: status reports etc...)
\->OTHER DOCUMENATION (this may be expanded
ie:downloading/uploading)
DOWNLOAD ---\
|->FTP
|->CVS
\->HTTP
UPLOAD ---\
|->SUBMISSION ENGINE (collect LSM data <--> preview -> commit)
\->SUBMISSION FORM FOR CVS ACCOUNT
LINKS ---> THIRD PARTY SOFTWARE (ie: links to cvs, trolls, kde, slashdot,
freshmeat)
CONTACT ---> CREDITS & IMPORTANT EMAIL INFORMATION
SITE MAP ---> possibly a site map if it seems to get too convoluted.
Every submenu above will have a submenu menu bar appended to the main menu bar
with the same look and feel, but differences to be able to show you where you are.

I Emailed Gordon Chaffee who's email address is in the documentation for
the kernel...
anyway he replied with a patch that was created by Max Cohan, so far It has
a small problem with the syntax, but I'm confident it will be included in
the next kernel...
The problem is not with the windows filesystem, and scandisk will not
help.. it is in the kernel source.

Hi,

It does not accept tm.tm_year > 99 as an argument (returns -1).
The documentation says that tm.tm_year is the number of years

It might - and it might not. The two systems have the same package
format, but they have slightly different package structures. I suggest
you install src rpm and modify the spec and/or make files.
