and use appropriately
- create more helper macros:
. cdev__xyz_init(c,n), such as cdev__ocri_init() for
/* open, close, read, ioctl */, etc.
. cdev__xRy_init(c,n), where nullop is used instead of enodev to dummy out
method `R' and the comments now read /* xxx (read) yyy */ instead
. cdev__xyz_t_init(c,n,t) - as per cdev__xyz_init, but sets d_type = t
as well
- use seltrue instead of dev_noimpl(poll,*), as (IIRC) cdevsw.d_poll should
always DTRT WRT returning a valid result. (a few devices previously
incorrectly returned ENODEV)
- use dev_noimpl(stop,enodev) instead of dev_noimpl(stop,nullop) if tty
== 0, because it doesn't matter if dev_type_stop isn't implemented in that
case, and it allows the use of the cdev__xyz_init macros. certain ports
(sparc,sparc64,x68k) used the nullop method for dev_type_stop in a few
drivers, whereas everything else uses enodev
- ensure that the comments are accurate WRT the behaviour of a given entry
and link it directly to db_command_table[] so that it's not necessary
to do this at runtime. Make db_machine_command_table[] const on all ports.
g/c now unneded stuff, like db_machine_commands_install(), db_machine_init()
Patch written by enami.
at tcds in files.alpha for now, and add a new `xasc at tcds' to files.pmax.
after pmax has moved fully to MI scsi (and `asc' is MI scsi), we should move
the device asc, etc., lines to files.tc.
rather than assigning to the whole field, set or clear individual flags,
which implies that the B_BUSY and B_INVAL flags will remain set.
this allows us to make the assertion in brelse() that B_BUSY is set,
which is the purpose of all this.
16 bit sun checksum. This flag is needed when making iso 9660 images which
are bootable on both sparc and pmax machines.

pseudo-device pty 2 # pseudo-terminals (Sysinst needs two)
(Some installers may not be using sysinst, in which case this just reduces
the number of ptys from 16 that are not used to 2 that are not used)

can not cross a page boundary. This fixes a problem when a dump(8) buffer
just crossed a page boundary and bus_dmamap_load() would coalesce the
the overlap onto the first segment. The NEXTPTR value would get set to
-1 when starting the DMA transfer and the residual data for unaligned
transfers would be copied to physical address 0x1ffffffc. On the R3000,
this would result in corrupted data, and on the R4000 would usually result
in a hard system hang.
both the primary and the secondary caches. MachFlushDCache() will not
invalidate the correct secondary cache lines for KSEG2 addresses.
R4000 systems should now be able to boot and run.

Also add commented out:
#options VNODE_OP_NOINLINE # Don't inline vnode op calls
#options NFS_V2_ONLY # Exclude NFS3 and NQNFS code

use BOOT_FLAG() in port's MD code as appropriate
as discussed on tech-kern, add new boot flags -v, -q for booting
verbosely or quietly, and corresponding AB_VERBOSE/AB_QUIET

NetBSD-specific bootquiet macro
for hpcmips, use new bootverbose instead of it's own hpcmips_verbose

to specify a minimum power-of-two alignment of the region.
How we ever got along without this for so long is beyond me.

ULTRIX/OSF1 call it so anyway.
- Squash IOASIC DMA buffer allocation into device attach() sequence.
- for sizeof(void *) == 8 arch, this is mandatory. MHLEN is too small
already (less than 80) and there are chances for unwanted packet loss due
to m_pullup restriction.
- for other cases, the change should avoid allocating clusters in most cases
(even when you have IPv4 IPsec tunnel, or IPv6 with moderate amount of
extension header)
portmasters: if your arch chokes with the change (high memory usage or
whatever), please backout the change for your arch.

"off_t" and the return value is a "paddr_t" to allow mappings

only changed the offset to a "vm_offset_t".

Specifying NULL instructs the driver to use default adapter and default
device codes. Every target port has ncr53c9x_attach(sc, NULL, NULL) anyway.
