implementations for these functions, we lean on GNU builtin functions
for using them, so these declarations are also conditional on using
a GNU compiler.
Move archtypes.h to include/ dir, since several servers require it. Move
fpu.h and stackframe.h to arch-specific header directory. Make source
files and makefiles aware of the new header locations.
-Convert the include directory over to using bsdmake
syntax
-Update/add mkfiles
-Modify install(1) so that it can create symlinks
-Update makefiles to use new install(1) options
-Rename /usr/include/ibm to /usr/include/i386
-Create /usr/include/machine symlink to arch header files
-Move vm_i386.h to its new home in the /usr/include/i386
-Update source files to #include the header files at their
new homes.
-Add new gnu-includes target for building GCC headers
this change
- makes panic() variadic, doing full printf() formatting -
no more NO_NUM, and no more separate printf() statements
needed to print extra info (or something in hex) before panicing
- unifies panic() - same panic() name and usage for everyone -
vm, kernel and rest have different names/syntax currently
in order to implement their own luxuries, but no longer
- throws out the 1st argument, to make source less noisy.
the panic() in syslib retrieves the server name from the kernel
so it should be clear enough who is panicing; e.g.
panic("sigaction failed: %d", errno);
looks like:
at_wini(73130): panic: sigaction failed: 0
syslib:panic.c: stacktrace: 0x74dc 0x2025 0x100a
- throws out report() - printf() is more convenient and powerful
- harmonizes/fixes the use of panic() - there were a few places
that used printf-style formatting (didn't work) and newlines
(messes up the formatting) in panic()
- throws out a few per-server panic() functions
- cleans up a tie-in of tty with panic()
merging printf() and panic() statements to be done incrementally.
process waiting for" logic, which is duplicated a few times in the
kernel. (For a new feature for top.)
Introducing it and throwing out ESRCDIED and EDSTDIED (replaced by
EDEADSRCDST - so we don't have to care which part of the blocking is
failing in system.c) simplifies some code in the kernel and callers that
check for E{DEADSRCDST,ESRCDIED,EDSTDIED}, but don't care about the
difference, a fair bit, and more significantly doesn't duplicate the
'blocked-on' logic.
- Make the bootstrap /etc/mk be populated from the newly checked out source
- Don't chmod 755 all of /etc
- For the 'real' /etc/mk installing, let the /etc/mk ownership and permission
come from the mtree file, delete the contents of /etc/mk, then copy the .mk
files over and set reasonable permissions and ownership. (So that the .mk
get updated from the real usr/src/ copies, and no other junk if anything,
after the bootstrap phase, whatever happened there.)
- as thre are still KERNEL and IDLE entries, time accounting for
kernel and idle time works the same as for any other process
- everytime we stop accounting for the currently running process,
kernel or idle, we read the TSC counter and increment the p_cycles
entry.
- the process cycles inherently include some of the kernel cycles as
we can stop accounting for the process only after we save its
context and we start accounting just before we restore its context
- this assumes that the system does not scale the CPU frequency which
will be true for ... long time ;-)
