Now console keyboard and display are connected at autoconfiguration time,

with IEEE, so use the "real" OUIs for definitions.
Now unfortunately vendors differ in how the MII ID register bits are
used wrt bit and byte ordering. There is a straightforward way - bits
numbered from LSB to MSB - used by AMD, Intel, NS and QS. This is used
by the current MII_OUI() conversion macro. ICS, Seeq, SiS and TI count
the bits as they appear on the wire, and some differ completely.
Account for these cases by "xx" prefixed OUI definitions which compensate
for this, so the MII_OUI() macro can still be used.
Add AMD (the "real" AMD this time) and the 79c973 PCnet internal PHY.

this is necessary to attach the PCI ultrasparc keyboard/mouse drivers.
firmware sets the "stdin" property of /chosen to be a pseudo-hid (yes, they
even spell it incorrectly) that merges all keyboard input into one stream,
so we can't find the USB controller we're attached to. Instead, just give
it to the first USB keyboard found during autoconfiguration. So that we
have SOMETHING available early on, use OpenFirmware i/o to do keyboard
input to the console wsdisplay until the USB code attaches the keyboard.

the child inherits the stack pointer from the parent (traditional
behavior). Like the signal stack, the stack area is secified as
a low address and a size; machine-dependent code accounts for stack
direction.

and "pass-filter" and "inbound" and "outbound" qualifiers in the filter
expression, use new "active-filter-in", "active-filter-out", "pass-filter-in",
and "pass-filter-out" without these qualifiers.
This is necessary due to the horrible, awful way "inbound" and "outbound"
were specified for the filter programs when a packet was passed through them.
Basically, the "address" byte in the serial PPP header was overwritten with
a value to indicate the direction. However, the "address" byte doesn't even
exist on PPP headers for all other PPP encaps! So, this old method worked
only for serial encaps, and corrupted packets for all others (PPPoE, ATM, etc.)

They manipulate MIPS processor's 8 interrupt sources and are used
as building blocks for NetBSD spl(9) kernel interface. Note that
MIPS processor doesn't enforce inclusive 'interrupt levels' found
in other processors, then the hierarchal nature of IPL must be
implemented by composing MIPS processor interrupt masks appropriately.
With the simplest target port in which small number of devices are
independently assigned with 6 external interrupt signal lines,
spl(9) kernel interface will be implemented with #define's of
processor interrupt controls mentioned above. In more general
cases, in which target computers have many devices and 'system
registers' indicating pending interrupt sources at any moment,
spl(9) will be implemented with more complex machinary manipulating
processor interrupts and system registers in target port dependent
ways.

the console. New algorithm:
* if stdin == keyboard, and parent of keyboard == adb, use ADB.
* else, must be a USB keyboard. Search backwards though the parents
until the USB controller is located. Determine its location in the PCI
domain, and which type of controller it is, and tell that controller that
it has the console input device. The USB code will then attach the first
USB keyboard as the console input device during autoconfiguration.

Unfortunately, this must still be deferred to autoconfiguration time,

necessary because some interrupt handlers may cause additional faults (e.g.
through R/M emulation) and thereby trash the previous fault state.
From Richard Earnshaw.
By code inspection I found 2 bugs in the ATAPI code, one may be the cause
of your problem: A counter is not reset when issuing the request_sense
command. This is c_skip, the counter used to track the offset in the data
buffer when a data tranfer needs multiple phases. The effect of this is that
the sense data transfered may be stored outside the sense buffer (sense buffer
+ some, potentially several KB, offset). This can only occur in PIO mode,
DMA is not affected.
This doesn't occur in "normal" use because when reading a data CD, either
the sense is issued for a non-data command (in which case c_skip stays to
0), or an error occured and no data has been transfered, and c_skip is still 0.
I can't see a case where a data READ/WRITE could cause a sense tranfer without
error.
The second problem is that b_resid can be set to a false value (resulting of
the sense tranfer and not the data transfer). Again this is not a problem with
usual data tranfers because both values ends up being 0 when no error occurs.
count is 0, wait for use count to drain before finishing the close.
This is necessary in order for multiple processes to safely share file

and _C_LABEL(syscall) in trap.c. In ELF they are the same. Change the label
in locore.s to be _C_LABEL(_syscall).
While I am there, move the register save and restoral code used in the
*sigcode trampolines into two macros and use them instead of copying 100
lines of assembly each time.
Now everything ELF works.
No flags will not work, because it will produce a kernel loaded at 0xf0000000.
This is because the bfd ELF pagesize (in elf32-sparc.c) is 0x10000. Since
we need to load at 0xf0004000, we use -n.
