Very good. Small remarks/questions: - I assume they learn the actual build procedure elsewhere. If not, than at least some pointers are needed. - The idea to patch the core for hooking into timer interrupts is very good for learning (the power of open source...). However, because the interrupt you talk about is (by incident) the timer, people may get the wrong idea that in Linux patching is needed for timing... (which is a very common task). You may want to mention the existance of the simple timer_* API. - Some mention (maybe verbally) about kernel versioning (which is used for their exercise?) -- Understanding the Linux kernel API's are a moving target (intentionally...) - Are they getting (maybe in their lectures) some orderly view about: * Different locking schemes?

This is quick, dirty, may not work, but most probably will. Be sure to have a backup copy of the original /sbin/init, and also make sure that you have some kind of rescue disc to boot from (knoppix and alike) in the not-so-unlikely event that your computer will refuse to boot.

[Haifux] gcc -pg, but no gmon.out
Hi fellas, I have a somewhat complex piece of code that needs profiling. It is composed of numerous Makefiles. I added -pg -g to the compiler parameters, but when the resulting binary runs, gmon.out is not created. When I create a simpler project (Makefile and code file set) to test this against, gmon.out is created correctly. Any thoughts? -- Bye, Shachar. -- Haifa Linux Club Mailing List (http://www.haifux.org) To unsub send an empty message to [EMAIL PROTECTED]

It is necessary, but not enough, to add -pg to the compilation phase, but you must make sure that the final linking is done with -pg as well, otherwise your program isn't compiled with the right bootstrap code that actually generates the gmon.out. Check to see that the cc -o progname object1.o object2.o ... line in the make output has the -pg parameter too. Also, as Orna pointed out, gmon.out is only created when the program exits. You must therefore make sure it indeed exits, and not, for example, killed with an uncaught signal. P.S. To your linking stage, you will most likely want to also add -lc_p. This will allow you to profile the standard C library calls as well. Without this, if you do a lot of library calls or IO you'll may have a lot of unexplained time in the profiling results. -- Nadav Har'El| Tuesday, Jan 27 2004, 5 Shevat 5764 [EMAIL PROTECTED] |- Phone: +972-53-790466, ICQ 13349191 |This space is for sale - inquire inside. http://nadav.harel.org.il | -- Haifa Linux Club Mailing List (http://www.haifux.org) To unsub send an empty message to [EMAIL PROTECTED]
