thorpej 07d023a3aa Define ELF32_EHDR_FLAGS_OK()/ELF64_EHDR_FLAGS_OK() and use it 
as an added measure to make sure that we can execute a binary.
These default to (1) if elf_machdep.h does not override them.

On Sun2, ELF32_EHDR_FLAGS_OK() checks for the presense of EF_M68000,
since the 68010 cannot run binaries for the 68020-and-up.

thorpej 9c3a981460 Just use the stock m68k/elf_machdep.h for now, so that things compile. 
A patch to handle EF_M68000 will be posted shortly.

soren 662f877587 MAXSLP is defined to be a machine-independent scheduling parameter, 
so move it into sys/param.h.

thorpej 47514a31be Remove unneeded declarations of the db_machine_init() function. The 
ARM ports are the only ones that actually have one, and it is about
to change.

fredette 65df8b69be Added the prom_kbdid function, to help us figure out if 
the console keyboard is on the parallel interface or zs1.

chris 0e7661f023 Update pmap_update to now take the updated pmap as an argument. 
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.

Currently this is a no-op on most platforms, so they should see no difference.

Reviewed by Jason.

fredette f76d90d237 Added comments and fixed some macros now that I correctly 
understand how to address the sun2 VME bus in the VM hardware.

fredette 5f35b65f29 Now define kernel_context() and restore_context(), these 
are used by some sun68k common code.

fredette 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.

fredette 54f88e2668 Corrected the value of DVMA_OBIO_SLAVE_BASE; obio 
devices can see the entire CPU address space.

fredette c5feae5dbf Now always define PGSHIFT. Thanks to the ELF move, note the new 
larger msgbuf size and different KERNBASE.

thorpej 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.

thorpej 69abdbf60c Undo a misguided previous change to the pmap_update() API. 2001-04-22 23:19:26 +00:00
thorpej 4738622712 Give pmap_update() an argument (a pmap_t) so that it knows which 
pmap it should be updating.
 2001-04-22 00:33:59 +00:00
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).

by hand.
Now define PMAP_OBMEM for completeness.

loaded by double-mapping pages by hand, outside of the pmap.
Added more prototypes for our bus_dma implementation.
 2001-04-06 13:09:10 +00:00
fredette 85c6ec3b50 Now use the proper DVMA map size depending on what 
machine type we're on.
