? I was not railing *against* the `get interesting kernel variable'
? syscalls, I was railing *for* them. There are too few. We could
? use a get_cpu_type syscall, in particular for the C library routines
? that use the fancy VAX instructions to do string operations. They
? run overly slow on the MicroVAX, since this machine traps on `locc'
? and `scanc' instructions and emulates them in the kernel.
?
? It would be nice, though, if it did not take a horrendous number
? of syscall table entries to describe all the interesting kernel
? variables; I argued for a call of the form
?
? get_kernel_variable(int variable_index)
?
? I still think this should be done.
Um, maybe I wasn't clear (won't be the first (or the last) time :-).
What I meant Chris meant is that he didn't want a separate syscall for
*each* interesting variable. He effectively wants (how do those words
taste that I'm putting in your mouth, Chris :-) to make nlist a system
call. How many things do you point nlist at besides the kernel anyway?
