08068ecc5d Don't unmap the PROM's first four physical/virtual pages 
inside pmap_bootstrap, instead we will wait until we have
installed our vector table.

39fb6a6f16 Now netintr and sun2_find_prom_map have prototypes in 
the common sun68k code.  Added prototypes for g0_entry
and g4_entry so that prom_abort() can use them.

7a083fffc2 Don't set up the g0 and g4 handlers here, now prom_abort()

7ab5601058 Since physical memory below 0x2000 isn't mapped anywhere 
for now, return EFAULT when /dev/mem tries to read it.
Other physical memory not managed by the pmap system is
mapped at the same virtual addresses.  Now that we
understand how VME PTEs are constructed, give mmapping
a VME bus a better chance of working..

find a PROM mapping for a device.

15b02e5ba0 Added a function, prom_sd_target, to translate a PROM 
sd unit number into a SCSI target.  Now only set up our
g0 and g4 handlers inside prom_abort(), so we're not
normally running with them.

edad0f956c Under _LKM, now undefine KERNBASE for declaring it. 
Not sure if this is correct, but the real question
is whether 68000 LKMs are even possible.

c5feae5dbf Now always define PGSHIFT. Thanks to the ELF move, note the new 
larger msgbuf size and different KERNBASE.
 2001-05-14 20:35:58 +00:00
fredette
1ef476f4a4 As a side-effect of the ELF conversion, the msgbuf 
can now be 8K large.  Removed more 68881 code that
is only useful if you have the real silicon, which
the 68010 never will.
 2001-05-14 15:36:42 +00:00
fredette
9ec520c479 Now, instead of swapping in and out the PROM's segment zero, 
swap in and out the mappings for virtual pages zero through three,
which are what the PROM really uses.  This is tied to the
move to ELF and the low memory usage changes.
 2001-05-14 15:12:39 +00:00
fredette
b49df54c83 One bonus of moving to ELF is that the boot loader on the sun2 
now loads the kernel into physical memory at the linked address.
So we link the kernel a little lower virtually, but the bootloader
actually will load it higher in physical memory than before.
This allows us to quadruple the size of the msgbuf to 8K, and
we also shuffle around tmp_vpages and the temporary stack.
 2001-05-14 15:07:23 +00:00
fredette
d36a2c2284 Made changes to support ELF. Highlights include: 
To find the kernel symbol table, instead of expecting
the old a.out struct exec from locore.s, use the
ELF headers found after the kernel text.
 2001-05-14 15:00:28 +00:00
fredette
f7c1abe426 Many changes to support ELF. Highlights include: 
Added % to all register names.  The boot loader now
loads us exactly where we're linked, so no PIC or
remapping funny business.  Removed more 68881 code
that is only needed with the real silicon, which
a 68010 will never have.

cf67ac7122 Per discussion w/ chuck and chuck, restructure the md page stuff 
to use a structure called "vm_page_md", and use __HAVE_VM_PAGE_MD
and __HAVE_PMAP_PHYSSEG.
 2001-05-01 02:19:13 +00:00
thorpej
2b27ac7a99 Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for 
each vm_page structure.  Add a VM_MDPAGE_INIT() macro to init this
data when pages are initialized by UVM.  These macros are mandatory,
but ports may #define them to nothing if they are not needed/used.

This deprecates struct pmap_physseg.  As a transitional measure,
allow a port to #define PMAP_PHYSSEG so that it can continue to
use it until its pmap is converted to use VM_MDPAGE_MEMBERS.

Use all this stuff to eliminate a lot of extra work in the Alpha
pmap module (it's smaller and faster now).  Changes to other pmap
modules will follow.

937a7a3ed9 Pull up the thorpej_scsipi branch to main branch. 
This is a completely rewritten scsipi_xfer execution engine, and the
associated changes to HBA drivers. Overview of changes & features:
- All xfers are queued in the mid-layer, rather than doing so in an
  ad-hoc fashion in individual adapter drivers.
- Adapter/channel resource management in the mid-layer, avoids even trying
  to start running an xfer if the adapter/channel doesn't have the resources.
- Better communication between the mid-layer and the adapters.
- Asynchronous event notification mechanism from adapter to mid-layer and
  peripherals.
- Better peripheral queue management: freeze/thaw, sorted requeueing during
  recovery, etc.
- Clean separation of peripherals, adapters, and adapter channels (no more
  scsipi_link).
- Kernel thread for each scsipi_channel makes error recovery much easier
  (no more dealing with interrupt context when recovering from an error).
- Mid-layer support for tagged queueing: commands can have the tag type
  set explicitly, tag IDs are allocated in the mid-layer (thus eliminating
  the need to use buggy tag ID allocation schemes in many adapter drivers).
- support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command
  will be requeued, or a REQUEST SENSE will be sent as appropriate.

1c3a62e066 Sprinkle pmap_update() calls after calls to: 
- pmap_enter()
- pmap_remove()
- pmap_protect()
- pmap_kenter_pa()
- pmap_kremove()
as described in pmap(9).

These calls are relatively conservative.  It may be possible to
optimize these a little more.

55044638aa Remove pmap_kenter_pgs(). It was never really adopted by

thorpej
7f10ba88b1 #define away pmap_update() in <machine/pmap.h> so that no function 
call overhead is incurred as we start sprinkling pmap_update() calls
throughout the source tree (no pmaps currently defer operations, but
we are adding the infrastructure to allow them to do so).

db8595f14f Much bus_dma work. When destroying a map, unload it if it's 
loaded.  Added more comments.  Fixed the perspective of a 24-bit
device from the original sun4 code to match the sun2.  For now,
we don't double-map pages into DVMA space by hand, we're back
to using pmap_enter.  Be more paranoid about saving and
restoring the MMU user context.
