- Add initial IOP support. ADB doesn't work yet for me, but it's here so
that others will be encouraged to work on it. ADB_HW_IOP basically
is configured as a NOP so that serial consoles will continue to work.
- Roll via1_intr and via2_intr into the intr.c scheme--this also required
changing rtclock_intr to grovel the stack differently so that hardclock
gets the right arguments and softclock() doesn't get all reentrant.
- Make via1 interrupts parallel to via2 interrupts--handlers get a pass-
through pointer and we can register handlers. Register via1 interrupt
with intr_establish()--normally level 1, level 6 for A/UX scheme.
- Use intr_establish() to set real via2 interrupt handler instead of the
hacked function pointer.
- Reorganize adb-direct interrupts so that a function call is removed.
- Implement A/UX interrupts for all Quadras right now. We may need to
special case some Quadras, but Linux folks are reporting success on
several models.
- Fix intrnames to be accurate for the normal, PSC, and A/UX interrupt
configurations.
"BUS_SPACE_ALIGNED_POINTER()".
Equal to the param.h "ALIGNED_POINTER()" normally, but obeys additional
requirements of the bus_space_xxx_n() macros. (BUS_SPACE_DEBUG)
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.
Adjust #include in kernel sources for machine/bswap.h.
- cpu_set_kpc() now takes void *arg third argument, passed to the
entry point.
- cpu_fork() allows parent to be non-curproc iff parent is proc0.
When forking non-curproc, assume its state has already been saved.
- Adjust various pieces of machine-dependent code to account of all of this.
the hp300 port.
- Interrupts 3-6 use this immediately. Interrupt 7 is a special case,
and the VIA interrupts (1 and 2) will be addressed when that code is
rototilled.
- Modify the zs front end to register with the appropriate interrupt
controller: through the PSC on the AV Quadras, and direct to
interrupt 4 on the rest. Arrange to have the appropriate zsc_softc
supplied to us at interrupt time.
- Modify the direct ADB driver (and its PowerManager cousin) to call
intr_dispatch(), rather than zshard(). XXX This is a kludge, but at
least limits the brokenness to the ADB drivers, now.
As a side effect, this should fix PR 5590. Thanks to Bill Studenmund for
correctly determining the cause of the problem reported there.
as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.
handlers. (Only slot_ignore() and slot_noint() need this, and we already
have a place to put this information.) Adjust add_nubus_intr() so that if
the client_data arg is specified as NULL, pass the slot number as
client_data to the interrupt handler.
