arch/tile has a dump_stack() entry point in assembly (see arch/tile/kernel/entry.S) that passes to _dump_stack(), which passes to dump_stack_regs(), which passes to tile_show_stack(). Similarly, show_stack() passes to tile_show_stack(), which does lots of work to cross into userspace and continue showing the stack if possible, print symbol info for both kernel and userspace, etc. I don't know if that's all supported fully in Tejun's generic version. Would it make sense for me to look at this after it's merged up into -next and see what tile needs? Unfortunately I'm taking off for a week's vacation so won't be able to do much until after the 23rd. -- Chris Metcalf, Tilera Corp. http://www.tilera.com _______________________________________________ Uclinux-dist-devel mailing list Uclinux-dist-devel@blackfin.uclinux.org https://blackfin.uclinux.org/mailman/listinfo/uclinux-dist-devel
