reference for making transferral of meta-information possible from
readdisklabel to bounds_check_with_label. The first (and maybe only)
thing that will use this is the multi-disklabel-format code on the
alpha where the labelsector is passed via cpu_disklabel so the label
write-protection can work correctly no matter what label was found.
Also use a new macro DKBAD to get at the dkbad field of the cpu_disklabel
implementations that contain it. This too is for multi-disklabel
architectures where the "bad" field can be inside a union. Use this
macro as a means for a driver to check if an architecture supports
dkbad constructs.
Remove proto of bounds_check_with_label from all MD disklabel.h as it
is in sys/disklabel.h.
I have not been able to test the changes everywhere, if I break anything
I apologize, and promise to fix it as soon as I become aware of it.

CAVEAT: turning off -O2 produces warnings about "defined but not used"
functions from libkern.h
removed internal copy of gets() replaced with call to getsn()
fixed #ifdef ... #endif mismatch in swapgeneric.c
fixed printf() in if_ie.c that was missing an argument
fixed si.c so that it compiles
added tags to all edited files

unsigned. should fix xdc watchdog timeouts noted in port-sparc
by nathanw@mit.edu.
|
|
|
|
NS,IPX,X.25 special processing is now handled in there.
reflect this amazing addition in all the ether ifaces.
ppl, pls check the stuff.

[1] check return value from malloc() for NULL before trying to bzero it.
[2] use "=" rather than "|=" when writing to CSR (otherwise you may
ACK something you don't mean to!).

minor clean up: revise locations of disk_busy/disk_unbusy calls to match xd.c
|
|
[prevents disk_unbusy panic when disk is loaded (if no
free IOPBs, xdstrategy() would queue the buffer for pickup
by xdcintr() but xdcintr() would never call disk_busy().
xdc_startbuf() is a better place since all bufs are routed
through here] problem detected by girish@dworkin.wustl.edu,
diagnosed and corrected by me.
- move disk_unbusy() call in xdc_remove_iorq() before the call to
XDC_FREE() [don't want to access a data structure that was just put
on a free list]
|
|
|
|
- move disk_attach() to before reading the disk label as per Jason.
otherwise we are reading into an unallocated buffer (oops!)

New generic disk framework. Highlights:
New metrics handling. Metrics are now kept in the new `struct disk'.
Busy time is now stored as a timeval, and transfer count in bytes.
Storage for disklabels is now dynamically allocated, so that the size
of the disk structure is not machine-dependent.
Several new functions for attaching and detaching disks, and handling
metrics calculation.
Old-style instrumentation is still supported in drivers that did it
before. However, old-style instrumentation is being deprecated, and
will go away once the userland utilities are updated for the new
framework.
For usage and architectural details, see the forthcoming disk(9)
manual page.

Change splimp -> splnet in Ethernet, ARCnet, and FDDI drivers.

Latest, greatest version of the new NCR driver.
DMA works! Interrupts work! Disconnect/reselect works!
To be paranoid, leave that all disabled for now...

New SCSI driver for the NCR5380, by David Jones.
Does DMA with interrupts. Much faster than our old
driver which did only PIO transfers. (Thanks David!)
Could be used on the amiga, and probably others...
