change these from bp->b_un.b_addr to bp->b_data, as well. This also
allows us more flexibility to experiment with other data buffer types
hung off of struct buf.
Unlike the other Sun machines, UltraSPARCs can have consoles run on different
chips than zs, so we need to support them. So, here we go:
Add a new PROM console driver with a major number and everything.
This is the default driver if nothing else attaches. It does not
use the keyboard driver since the PROM translates keystrokes itself.
(Unfortunately it also swallows L1-A).
Have the keyboard driver take over the console when it attaches on a
serial port. When a serial port detects a keyboard and attaches the
keyboard driver, it needs to provide a set of consdev vectors. They
keyboard driver will use those to send I/O to the keyboard and mouse.
just one copy of this.
- remove duplicate setting of sgsize in iommu_dvmamap_load().
- fix DIAGNOSTIC check in iommu_dvmamap_load_raw() to panic() in unexpected
conditions only (not normal ones), and also add an extra case.
it to determine the boot device: mvme68k, pc532, macppc, ofppc. Those
platforms should be changed to use device_register(). In the mean time,
those ports defined __BROKEN_DK_ESTABLISH.
contains the values __SIMPLELOCK_LOCKED and __SIMPLELOCK_UNLOCKED, which
replace the old SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED. These files
are also required to supply inline functions __cpu_simple_lock(),
__cpu_simple_lock_try(), and __cpu_simple_unlock() if locking is to be
supported on that platform (i.e. if MULTIPROCESSOR is defined in the
_KERNEL case). Change these functions to take an int * (&alp->lock_data)
rather than the struct simplelock * itself.
These changes make it possible for userland to use the locking primitives
by including <machine/lock.h>.
- make some debugging messages in iommu_remove() saner and add some more.
- decrement 'len' in the no streaming buffer case, also.
- in iommu_dvmamem_map(), do not enter these mappings into the IOMMU,
only into the CPU (the former is done at _load time).
- make a panic that shouldn't happen a DIAGNOSTIC.
- merge IOMMU DVMA code from sbus/psycho into iommu.c. this code was
identical and a few minor inconsistencies had crept in. this way
keeps them all in sync.
- with this code gone from psycho, merge the psycho.c and psycho_bus.c
files. same with ebus/ebus_bus.c. delete the _bus.c files.
- add a _ds_boundary member to the dma segment structure, so that later
dma mappings can find this value.
- set _ds_boundary in machdep.c:_bus_dmamem_alloc().
- kill much dead code.
- make GENERIC64 include GENERIC and set the 3 optoins it needs. suggested
by hubert feyrer.
- add a comment that we maybe should use the `bpp' driver, not the lpt, on
the ebus because the `bpp' driver does DMA already.
- ebus_attach_args got a member renamed
