Socket 8 to 370 converters. When (1) CPU_PPRO2CELERON option is
defined, (2) Intel CPU is found and (3) CPU ID is 0x66?, L2 cache is
enabled through MSR 0x11e. The L2 cache latency value can be
specified by CPU_L2_LATENCY option. Default value of L2 cache latency
is 5.
These options are useful if you use Socket 8 to Socket 370 converter
(e.g. Power Leap's PL-Pro/II.) Most PentiumPro BIOSs don't enable L2
cache of Mendocino Celeron CPUs because they don't know Celeron CPUs.
These options are needles if you use a Coppermine (FCPGA) Celeron or
PentiumIII, becuase the L2 cache enable bit is hard wired and L2 cache
is always enabled.
What we'd like to know is whether or not we have a listener
upstream that really hasn't configured yet. If we do, then
we can give a more sensible reply here. If not, then we can
reject this out of hand.
Choices for what to send were
Not Ready, Unit Not Self-Configured Yet
(0x2,0x3e,0x00)
for the former and
Illegal Request, Logical Unit Not Supported
(0x5,0x25,0x00)
for the latter.
We used to decide whether there was at least one listener
based upon whether the black hole driver was configured.
However, recent config(8) changes have made this hard to do
at this time.
Actually, we didn't use the above quite yet, but were sure considering it.
was found or not. Fix it's usage. Alas, it caused no problem before,
besides leaving garbage in the stack, because refill, used by [if]
[else] [then], was broken.
using decimal major and minor numbers. "ls -l" reports
disk partitions using decimal major numbers and hex
minor numbers.
make specfs use decimal major numbers and hex minor numbers,
just like "ls -l"
Generated a new macor, RAY_RECERR for reporting errors with. Verbosity set with IFF_DEBUG (recommended at present).
Add PRIBIO to tsleeps.
Catch detach on ray_ccs_alloc a little better.
Move sc_promisc into desired and current n/w parameters.
Remove IFQ_PEEK, we know the driver runs okay without it.
Drain the output queue in ray_stop.
Only use ray_mcast for ADD/DEL multi ioctls. ray_init_multi resets the
multicast list on startup. Simplifies ray_init a little.
Tidy some old comments.
ray_download_done now copies the whole desired n/w parameter set into the
current set. This is because I was missing soem parameters - like the
net type!
required (rounded up a little) instead of twice the previous amount (or
a fixed amount for the first allocation).
The bug caused memory corruption when a new unit number for a devclass
was more than about twice the previous maximum one (or more than 3 for
the first one), so it corrupted memory (which happened to be the atkbdc
port resource list) in the reporter's configuration with sio unit
numbers { 0, 25, 1, 2, ... }.

2. Newbusify the driver.
3. Build as a module.
4. Use correct minor numbers when creating device files.
5. Correctly lock control characters.
6. Return ENXIO when device not configured.

Note:
- the old driver still lives in src/sys/i386/isa, so that you can
revert to it if something goes wrong.
- The module does not detach very well. Attaching works fine.
config(8). This commit allows control of the creation of the
#include "foo.h" files. We now only create them explicitly when needed.
BTW; these are mostly bad because they usually imply static limits on
numbers of units for devices. eg: struct mysoftc sc[NFOO];
These static limits have Got To Go.
map physical addresses below 0x2000 (accoding to AMI). If we
allocate our s/g tables and get an address below this point, leak the
memory and try again.
This should fix booting from these controllers.
Get ray_detach working correctly. This is a very simple routine as it
just wakes up sleeping processes. Note that anything woken has NO softc
structure available! runq_add is suitably modified to detect a detach and
return straight away.
Due to ray_detach and its implications use a macro for adding things
to the runq in user land.
