as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.
making performance of bus_dma drivers not completely suck on the DECstation.
XXX R4000 case is still abysmal, because some other data structure

controllers (including SCSI id 7 on the 2100/3100).
- On the pmax (2100,3100) set the host SCSI id to 6.
- Move disk and tape config for the second ASC controller from the GENERIC
config file to scsi.pmax so all configurations can use the second
controller.
* ibus (virtual bus for baseboard direct-attach deviecs)
* 5100 support, using ibus
* rename "clock" to mcclock for future support of Qbus machiens

for other DEC systems which use mcclocks with each onchip byte
register padded out to a 32-bit word.
Clone alpha/alpha/mcclock (also duplicated in pmax port) into
sys/dev/dec, and ifdef for default clockrates on pmax and alpha.
Use new machinery on pmax for ibus,ioasic attached mcclocks.
read and write compare register (controls cycle-driven periodic interrupt).
Use cycle counter for microsecond time on mips3, but for now only on
3min motherboards (5000/150). the MAXINE baseboard microsecond
counter is more stable and I don't ave no 5000/260 to test.
XXX clkread() is a mess, it should be rewritten.
XXX should add nanotime() to give inkernel nanosecond resolution,
and then microtime() reworked to use nanotime().
* dec_5100.c: sysconf, interrupt, and motherboard (drain writebuffer)
support for 5100.
* support for hardware kludge in 5100: sii DMA buffer is hardware
padded to alternate 32-bit words, not alternating 16-bit halfwords.
* 5100 has no framebuffer, console is wired to serial port 0.
With ibus support, boots as far as exec'ing init, and hangs.

Add markers for where MNN probes for configurations with a mixture of
RAM sizes and for Prestoserve NVRAM (in normal RAM slots) should go.
interrupt-callout vector from mips locore dispatch code to port code.
* Move branch-emulation declaration to mips/include/trap.h.
* Garbage-collect pmax/pmax/trap.h.
Not needed now pmax/pmax_trap.c is gone, and after above tidy-up.
Replace all DS5000_* and DS3100 ifdefs with ifdefs on DEC_ options.
* Use MI declarations, not pmax-specific, in model-specific init
that uses baseboard (ioasic) registers.
* Further cleanup of machdep.c. Clock-tick still needs more thought.
* Use 'ibus' names for 3100 baseboard devices in MI code.
* add "Platform" support inpmax/pmax/sysconf.c and pmax/include/sysconf.h
(based on Alpha cpuconf.[ch], with a namechange to avoid clashes with
support for models of MIPS cpus. They differ more than Alphas).
* For each supported model of DECstation, create a separate file
with the support for that model. Use model codenames, since
support is really baseboard-specific and CPU daugherboards can change.
Move code from machdep.c and pmax_trap.c,
Add sysconf (nee "cpuconf") support.
* Rename model-specific functions to match sysconf names.
* Clean up autoconf.c. Use platform callbacks.
* Retire pmax_trap.c.
Leaves I/O bus configuration and console configuration untouched.
as pmax/dev/findcons.c:
* Follow the same logic: look for the device the PROM is using.
* If it's a framebuffer and we don't have a driver for it, try other
* framebuffers in PROM search order.
* If no match found, warn user and fall over to serial console.
* if no serial console found, go back to PROM.
Rework tc/scc.c attach routine to give cleaner initialization semantics.
Prune out old 'braindamage' code.
* Do rcons output properly, using cn_tab->cn_dev which points
at rcons cdevsw entrypoints.
* The pmadx console code was using keyboard (serial) device
(major,minor) for raster consoles with special code in the keyboard
drivers to catch output intended for consoles, pull it off the device
queue, and print them via cnputc().
Ifdef out RCONS_BRAINDAMAGE.

keyboard input on a 5000/50 under load.
Increasing the DELAY() from 2 to 30 doesn't help. Remove it for the
1.3 release. May cause problems with low-speed serial input, but
console keyboards work properly.
* Add code to query CDs for size, from MI scsi cd.c. Use it on CDs.
* Set C partition size for CDs. 4.4bsd/pmax code only set `a' partition
size and required users to mount `a' partition, breking raw-device
access like "disklabel rz?".
* Avoid possible divide-by-zero call to howmany() from rzstart(),
on removable media that aren't ready at device-open time.
Verified to work on rrz42.
until a proper fix is available:
Perpetuate the 4.4bsd design even further. Change keyboard-driver
open routines to check for an active raster console. If active, set the
keyboard struct tty's t_winsize from the rcons t_winsize on first open.
See pr 4438 for remaining problems and discussion of a complete fix.
* add includes for sys/dev/scsipi headers.
* cut-and-paste mode_sense and disk-geometry sense code from sd.c,

* Write `rz_command()' to send SCSI sense commands based on
existing rz size-sensing code.
* get geometry info with page 4 and page 5 mode sense.
* use resulting geom info for default label, fake label, and when
using ultrix labels. (ultrix labels have no geometry info).
Fixes incrrect-label bugs with using sysinst to install onto
Ultrix-labelled disks.
* Check for a disklabel matching the known values in an install diskimage.
If found, update incore disklabel's RAW_PART with the size reported
by the disk, clobbering the size used by vnd(4).*
* If geometry info is bogus or /missing, supply a fake geometry
(as in sd.c). Saves readdisklabel() and sysinst from divide-by-zero errors.
* lint: RAWPART -> RAW_PART.

* Move if_le_dec.c with DEC padded LANCE-dma (pmax/pmax, ioasic, vax 3400)
to sys/dev/dec. Remove from sys/dev/tc.

Add compile-time MIPS3-only, compile-time MIPS1-only, and
runtime (both) definitions for number of TLB ASIDs (tlb pids)
and shift count to extract a TLB pid.
* locore.h:
Delete unused vector slot for indexed TLB writes.
mips1 and mips3 TLBs are different enough that we have

mips3 and mips1 specific code paths (e.g., creating the kernel stack
for process 0).
Add `options MIPS3' to pmax/conf/GENERIC.
* cpuregs.h:
Delete unused VMMACH_ names (e.g., duplicates of PTE bits in pte.h).
Change remaining VMMACH_xxx names to MIPS1_xxx or MIPS3_xx.
Fold remaining compile-time definitions into a single #ifdef MIPS3.
* Use MIPS1_ names in locore_r2000.S, mips3_ names in locore_r4000.S
* Garbage-collect MachHitFlushDCache()
* psl.h:
use MIPS1_, MIPS3_ symbolic names for Cause register bits.
change _R3K to MIPS1_, _R4K to MIPS3. Conditionalize for mips1 only,

similar design and code by Jason Thorpe and Jonathan Stone.
NOTE: the kernel-stack-switching code and cacheflush() calls in
locore.S still use #ifdef MIPS3 and need more work.
mips/include/cpu.h:
Add CPUISMIPS3 for run-time tests of what CPU architecture level
we're running on.
mips/include/locore.h:
Add declarations of locore cache-size variables for ref/def toolchain.
mips/include/mips1_pte.h:

mips/include/mips3_pte.h:
mips3 TLB bit definitions.
mips/include/pte.h:

that expand to CPU constants if only one CPU arch is configured,
or to inline functions if both MIPS1 and MIPS3 are configured.
mips/mips/locore_r2000.S:
Use MIPS1_PG_xxx constants inside mips1-specific code.
mips/mips/locore_r4000.S:
Use MIPS3_PG_xxx constants inside mips3-specific code.
mips/mips/locore.S:
Use MIPS1_PG_xxx constants inside mips3-specific code.
Use MIPS1_PG_xxx constants inside mips1-specific code.
(Needs more work!)
mips/mips/{pmap.c,vm_machdep.c,trap.c}, pmax/pmax/machdep.c:
Use MIPS3_PG_xxx constants inside mips3-specific functions,
and MIPS1_PG_XXX inside mips1-specific code.
Otherwise, use mips_pg_XXX_bit() macros where they apply,
and use "if (CPUISMIPS3) { ... } else {... }" where they don't.
mips/mips/mips_machdep.c:
Import Michael Hitch's fixes from the pmax locore-init code
into mips_vector_init().
pmax/pmax/machdep.c:
Use generic mips_vector_init() locore vector-init function.
Move mips-specific pmap definitions (PMAP_PREFER for mips3, declaratin
of pmap_bootstrap() for the system-specific machdep.c) from
arch/pmax/include/pmap.h to arch/mips/include/pmap.h.
* Move declaration of locore communcation variables (CPU family,
cache sizes, etc) to mips/include/locore.h. Delete from
pmax/include/cpu.h and older versions from pica/include/cpu.h.
* Move definitions of CLKF_BASEPRI, CLKF_USERMODE to mips/include/cpu.
* Delete duplicate definitions in pica/include/cpu.h, pmax/include/cpu.h.
Change pmax/include/psl.h to just do #include <mips/psl.h>.
pmax/include/psl.h would go away completely if it wasn't stil required

* If the chip asserts a SCSI-bus error (SII_BER) in sii_intr,
reset the SII_BER bit instead of ignoring it.
XXX SII_BER May need checking and resetting elsewhere.
Fixes broken blitting from rcons.
* Put back old 4.4bsd range test on cursor movement. 1.2 code is broken.

Eliminate obsolete global kernel variable "struct timezone tz"
Add RTC_OFFSET option
Add global kernel variable rtc_offset, which is initialized by
RTC_OFFSET at kernel compile time.
on i386, x68k, mac68k, pc532 and arm32, RTC_OFFSET indicates how many
minutes west (east) of GMT the hardware RTC runs. Defaults to 0.
Places where tz variable was used to indicate this in the past have
been replaced with rtc_offset.
Add sysctl interface to rtc_offset.
Kill obsolete DST_* macros in sys/time.h
gettimeofday now always returns zeroed timezone if zone is requested.
settimeofday now ignores and logs attempts to set non-existant kernel
timezone.
on indirect-config busses a (permanent) softc that they could share
between 'match' and 'attach' routines:
Define __BROKEN_INDIRECT_CONFIG so that old autoconfiguration
interfaces are used, until drivers are converted to use the new

which prohibit indirect configuration devices from receiving a softc
in their match routine that they can share with their attach routine.

rather than using mipsI_ and mipsIII_).
Where CACHED_TO_HYS() is still needed for kernel-virtual-to-physical
or physical-to-uncached mapping (fb drivers), replace with
`#include <mips/cpuregs.h>'.
* dcparam() with normal tty t_param interface, which calls
* cold_dcparam() called with explicit dc7085 register address
and flags, which does the work and is also callable when cold,

* Move mips-I pte (TLBlo) definitions from pmax/include/pte.h
to mips/include/mips1_pte.h
* Move mips-III pte (TLBlo) definitions from pica/include/pte.h
to mips/include/mips3_pte.h
* Add new mips/include/pte.h, which includes exactly one of
mips1_pte.h or mips3_pte.h (which still have namespace collisions),
depending on "options MIPS1" or "options MIPS3". (hack).
Move soft kvtopte(), ptetovk() definitions to mips/include/pte.h
* Add macro PTE_TO_PADDR() to hide the different hardware TLB formats
when mapping from pte to physical address.
* Add macro PTE_READONLY() to hide lack of SW read-only bit in mips-III
tlb. (mips1 pmap uses a sw bit in the PTE, mips3 looks up RO bit in
the kernel pmap.)
* Use macros (not direct TLB frobbing) in mips/trap.c, to make it
mips-1/mips-III indepenndet.
* Change {pmax,pica}/include/pte.h to just do #include <mips/pte.h>.
NetBSD-current changes:
* change include paths to be relative to the kernel-source tree
(e.g., `/sys') instead of arch/pmax/conf.
* add explicit options for exec packages (EXEC_ELF32, EXEC_ECOFF
for COMPAT_ULTRIX)
* comment out references to still-unsuppoted MI scsi.

1. Start at the specified entry instead of entry 0.
2. Use the blue value instead of the green when setting the blue color entry.
3. Don't use the starting index again for storing the saved entry - the cmap

a hard hang on the maxine when console output is done after calls to
set the color map (usually by the X server).
* Add changes needed/used to build 1.2 GENERIC kernel:
* Delete obsolete and ambiguous DS5000 option.
* Add CPU_R3000 which is now required to compile in mips1 locore support.
* Add an explicit declaration of HZ.
* back out COMPAT_12 for this revision.
