Is there a method of tracing function calls in the kernel? I looked at ktrace, but that only gave me the syscalls and returns from syscalls. What I want to see is the "complete" chain of kernel calls. For example, on a read() I'd like to be able to see its interactions with filesystem layers, unified buffer cache and even the I/O Kit ATA drivers if possible. Any help would be greatly appreciated. -Joey Joseph G.
