inconsistent when we do not do it for swap or vnode.
We still printf for preloaded disks because of the weak debugging
options people have in embedded/tiny environments where this is
usually used.
pointer types, and remove a huge number of casts from code using it.
Change struct xfile xf_data to xun_data (ABI is still compatible).
If we need to add a #define for f_data and xf_data we can, but I don't
think it will be necessary. There are no operational changes in this
commit.
expectation.
This solves the problem, where in a constellation with two (or more)
drives, an attempt is made to access a device name for that device
using a historic partition letter, like /dev/fd1c. This is supposed
to create a symlink to the master device, but previously, the link was
always created to /dev/fd0, even if the request was for fd1*.
aac.c:
Re-arrange the interrupt handler to optimize the common case of
the adapter interrupting us because one or more commands are complete,
and do a read across the pci bus to ensure that all posted status
writes are flushed. This should close a race that could cause command
completion interrupts to be lost.
Follow the spec a bit closer when filling out command structures.
Enable the Fast Response feature to eliminate the need for the card
to DMA successfull command completions back into host memory.
Tell the controller how much physical memory we have. Without this
there was a chance that our DMA regions would collide with the
memory window used by the cache on the controller. The result would
be massive data corruption. This seemed to mainly affect systems with
>2GB of memory.
Fix a few whitespace problems.
aac_debug.c:
Add an extra diagnostic when printing out commands.
aac_disk.c:
Add extra sanity checks.
aacreg.h:
Prepare for making this 64-bit clean by reducing the use of enumeration
types in structures.
Many thanks to Justin Gibbs for helping track these down.
is read one clock edge too late. This bit is driven low by
slave (as any other input data bits from slave) when the clock
is LOW. The current code did read the bit after the clock was
driven high again.

This abstracts out all the differences I could see between the netbsd
sparc64 and macppc zs drivers. In particular the offsets of the csr and
data registers are different, so we use a separate bus handle for each and
use bus_space_subregion to add the bus specific offsets.

as separate 16-bit entities. Some of the ring control blocks are
in NIC memory, so they must be referenced using 32-bit accesses.
Smaller accesses have been observed to fail under some conditions.
This caused the rings to be set up wrong, leading to writes by the
card outside of the intended bounds of the rings. This problem was
diagnosed by Michael Barthelow. Don Bowman submitted a patch which
fixed the problem using a slightly different approach.
Reference ring control blocks in NIC memory using a pointer to

Parenthesize the BGE_HOSTADDR macro definition properly.

from the hardware descriptors to avoid the overhead of having a DMA
map for each of them. Bump the number of hardware descriptors to 128,
and use half as many software descriptors for now.
Some minor cleanups.
- remove DPRINTF(), there is a CTR*() for any of them, and KTR is
far more useful to debug this driver.
- some cleanups; remove some unused code and definitions.
o create a separate tag for each object allocated with bus_dmamem_alloc so
the tag's maxsize is setup appropriately; this reduces memory allocation
for the queue descriptors from 16M to what it should be and also fixes
memory allocation for public key operands
o release bus dma resources on detach so module usage doesn't leak
o remove public key op disable now that bus dma memory allocation is fixed
o collect attach error handling in one place
