locore calls to go via a locore-entry jumptable.
Use the mips/mips/mips_machdep.c code to initialize locore state,
exception vectors, and the locore entry vector, instead of doing
it all in mach_init().
Update dumpsys() to use new-style signatures for dump routines,
even though the pmax SCSI drivers don't actually support dumping kernel
memory.
locore calls to go via a locore-entry jumptable.
Cast the (int) arguments to MachTLBUpdateEntry() to avoid
warnings. Variables TLB entries are still type-punned as either structs
or ints, without any regard, when the pmax-specific VM code passes
them as arguments to functions.
locore calls to go via a locore-entry jumptable.
Use mips_btop(), mips_round_page, mips_trunc_seg() instead
of pmax_btop(), pmax_round_page, pmax_trunc_seg().
Add Per's software-readonly-bit mechanism, since the r2000 and r4000
hardware TLB entries are very different, and the r4k has no space for
software bits in TLB entries. That is, this pmap code still won't work
on r4000 machines. Some other solution, like another jump table for
clients of the pmap code, is necessary.
locore calls to go via a locore-entry jumptable.
Declare r2000- and r4000-specific exception-handler functions, to which
trap() and interrupt() dispatch exceptions. Initialize r2000- and r4000-
specific exception-handler vectors, when CPU_R4000 and CPU_R2000 are
defined.
Update the stack-traceback code (partially) to understand and print
the new low-level exception-handler code, via which machine exception-vectors
send exceptions to call trap() or interrupt(). This needs more work.
It just causes a kernel panic, and will until the rest of the pmax
autoconfiguration is redone to use a bus-specific probe and attach
argument, or until KN01 devices are no longer attached to the mainbus.
an vector (struct) of function pointers. Add prototype declarations for
each vector entry.
Add declarations for the r2000 (MIPS-I) and r4000 (MIPS-III) locore
versions of the relevant functions.
update the 4.3bsd/Ultrix-compatible qvss-style mmap'ed framebuffer/input-event
code to use mips_round_page() et.al., not pmax_round_page().
Add explicit "int" return types to functions. Add prototyped forward
declarations.
Fix the the definitions of dtop cdevsw entry point functions to match
their declarations. Add explicit "int" declarations to functions.
Add prototyped declarations for all local functions.
Return zero from dtopstop().
Include the external declarations from dtopvar.h.
to all mips ports.
So far, this consists of code to initialize a vector, or jump-table, of
pointers to locore functions that require different definitions on different
Mips CPUs (eg., r2000/3000 and r4000); a generic wrapper for setting up
CPU-specific exception vectors; and CPU and FPU identification code.
locore functions. The new names are used by C code to construct a jump-table,.
making it less infeasible to have a single kernel image work on both
r3000 and r4000 systems.
independent z8530 driver. When that driver is updated, the local copy
of those files may be removed. From Bill Studenmund.
Compiler warnings fixed by me.
This is used by the i386, hp300 and mac68k ports.
- Added exec_aout_prep_oldomagic, and exec_aout_prep_oldnmagic
These are just copies of the respective prep functions from
kern_exec.c with text address starting at 0. Maybe a better fix
is to pass the starting address as a third argument so we don't
duplicate code, but this could be the next pass since the functions
are used in many places. These functions are used for BSDI binaries.
calling uname(3) can find out what os it is running on. Tested only with a
bsdi binary that calls getkerninfo directly. Funny thing is that I ran
the same binary on a bsdi machine, and they fill in fewer fields in the
emulation than we do; maybe I went overboard :-)
