Re: getting module symbols into ksyms
kernel = 2.2.14-5.0 for i686 UP insmod reports version 2.3.10-pre1 ksymoops is 0.7c If the insmod version is not the same as modutils some guidance on finding the modutils version would be appreciated. (The system installed is the RedHat 6.2 distribution.) Thanks in advance.

Re: getting module symbols into ksyms
Yes, I know about the HTML crap. I realized after I sent it what I had done and knew I'd get flack about it. Regarding the issue, I'm using 2.2.14-5.0. I'll have to check version of ksymoops and modutils. It's too bad that a seemingly simple question like this ends up being so complicated. I'll get the details. - Original Message - From: "Keith Owens" <[EMAIL PROTECTED]> To: "Jerry Kelley" <[EMAIL PROTECTED]> Cc: "linux kernel" <[EMAIL PROTECTED]> Sent: Saturday, October 21, 2000 9:11 PM Subject: Re: getting module symbols into ksyms > On Sat, 21 Oct 2000 10:41:08 -0500, > "Jerry Kelley" <[EMAIL PROTECTED]> wrote: > >I'm trying to debug the oops that my module is generating.

getting module symbols into ksyms
I'm trying to debug the oops that my module is generating. When I use ksymoops on the oops text I get a warning saying that the module is in lsmod but is not found in ksyms. I have two questions: 1. How do I get my symbols into ksyms? 2. Are only exported symbols in ksyms? Translation: Will I have to export all of my routines in order to effectively debug the module? (I assume that only exported symbols are in ksyms and will build a debug version that exports more routines in the debug version but not in the release version.) Thanks. I realize that these are probably very rudimentary questions but I'd rather ask the experts rather than wander around. Jerry Kelley [EMAIL PROTECTED]

info on Oops
Is there a good primer on reading an Oops? I'm also looking for general tips on configuring the kernel and my module so that a useful stack trace is generated - entry points show function names rather than addresses. The obvious is to build with debugging turned on but is it necessary for the kernel to be built with debugging turned on to effectively trace back through a crash? It seems that the Oops in the messages log resolves symbols but on the console I only get function addresses.

acquiring resources shared or exclusive
I have a rudimentary question as I'm new to the Linux kernel. Is there a resource that can be acquired shared so that multiple threads can read data from a protected region and not block each other? It seems that the semaphore in the Linux kernel is only exclusively acquirable. I need to be able to share read access from several threads to some global structures and don't want them to block. I do want blocking whenever I have to modify the structures though. Thus I'm looking for a way to perform synchronization for reads (shared) and writes (exclusively) in the kernel. I assume it can be done it's just that I'm not sure how to do it yet. This is probably a very easy question. Thanks in advance. --- Jerry Kelley [EMAIL PROTECTED] - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
