Can anyone confirm if the patches to valgrind mentioned below have found there way into the release? I will be attempting this with 2.4.20-6um. Any words of wisdom appreciated. Has anyone used this combination succesfully? I wonder what "teaching valgrind about the false positives" entails. thanks for any info, GSM >bulb@ucw.cz said: >> Is it possible to run 2.4.20-3um (or -4um - I have not got around to >> updating yet) under valgrind? >> >> Does it need some specific config options to work? > >Any recent UML is as valgrindable as the UML mentioned in the post you >saw. > >You need CONFIG_MODE_SKAS, !CONFIG_MODE_TT, and >CONFIG_KERNEL_STACK_ORDER=3. > >You also probably need some valgrind patches unless the stuff I and >Jeremy >have done have been merged into valgrind CVS. > >Once valgrind is working, you need to go through the false positives and >teach valgrind about how the kernel deals with memory allocation.
