* [parisc-linux] Feature request for parsic kernel hackers (2 mini-projects) @ 2005-08-01 4:57 Carlos O'Donell 2005-08-01 9:59 ` Randolph Chung 0 siblings, 1 reply; 3+ messages in thread From: Carlos O'Donell @ 2005-08-01 4:57 UTC (permalink / raw) To: parisc-linux parisc, I have two small kernel hacker projects. 1. Add cr27 printing to HPMC, this would let someone debug multi-threaded problems by examining the thread register. It would be even cooler to make this NPTL aware and dump the TCB and DTV. 2. Add some option that enables the user to print something like /proc/self/maps when a user process dies. This is very usefull for translating a fault address into a quick estimate of which library function crashed. Fame and glory? My gratitude? :) Cheers, Carlos. _______________________________________________ parisc-linux mailing list parisc-linux@lists.parisc-linux.org http://lists.parisc-linux.org/mailman/listinfo/parisc-linux ^ permalink raw reply [flat|nested] 3+ messages in thread

In particular the PA8800 crashes are so weird that I can't get the same thing under the debugger. Also, when a process dies in gdb 6.x it throws away the process information and I can't look at the maps anymore. I have to let it die, remember where it died, start it again and then hope the DSO loading was deterministic (e.g. No weird use of dlopen). c. _______________________________________________ parisc-linux mailing list parisc-linux@lists.parisc-linux.org http://lists.parisc-linux.org/mailman/listinfo/parisc-linux ^ permalink raw reply [flat|nested] 3+ messages in thread
