The *nix statfs() API seems limited to 32bit file lengths, unless i'm misunderstanding something. Can someone send me a quick example of how to do this?

I have a panic log from an intel machine. I've made symbol files for the "Kernel loadable modules in backtrace", but the backtrace is in the format: Format - Frame : Return Address (4 potential args on stack) e.g. 0x485ebc08 : 0x128d1f (0x3c9540 0x485ebc2c 0x131df4 0x0) what do I plug into gdb to get the symbol name at that address? Everything I've tried so far has resulted in this type of message: (gdb) x/i 0x485ebc08 0x485ebc08: Cannot access memory at address 0x485ebc08 (gdb) x/i 0x128d1f 0x128d1f: Cannot access memory at address 0x128d1f If you have the correct kernel debug kit mounted and loaded in gdb the try "info line * 0x128d1f". -Shawn _______________________________________________ Do not post admin requests to the list.

Re: 64-bit aware vmmap?

site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com I need to diagnose a problem with my driver mapping memory into user space for 64-bit apps on Intel. I tried to use vmmap for this, but it seems to not understand 64-bit applications. Is there any alternative, like /proc/*/maps on linux? http://www.sealiesoftware.com/vmmap64.c -- Greg Parker gparker(a)apple.com Runtime Wrangler _______________________________________________ Do not post admin requests to the list.
