andvar | change #define to #error for MIPS3_4100i 8KB page size build protection.
|
| 1.31 |
| 17-Aug-2020 |
mrg | port crash(8) to mips. (most of the kernel side.)
- expose parts of _KERNEL to _KMEMUSER as well
- hide more things for _KERNEL
- avoid DB_MACHINE_COMMANDS in crash(8)
- XXX add mips_label_t for !_KERNEL and use it in the pcb to
avoid conflicting with the ddb/crash one
- enable dumppcb
some changes to make stack trace fail instead of SEGV and
the userland changes to crash itself not part of this change.

support BUS_SPACE_MAP_PREFETCH in order to allow mapping device memory and
DMA buffers with cacheing disabled but things like write combining, relaxed
ordering etc. allowed when the CPU supports it
so far enabled only on Loongson, should work on R1xk and probably newer CPUs

garbled | branches: 1.23.20; 1.23.38;
Merge the ppcoea-renovation branch to HEAD.
This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.
TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.
NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

tsutsui | Make MIPS3_PG_SHIFT a variable and initialize it accordingly
in mips_vector_init() if options MIPS3_4100 is specified
so that kernels which have options MIPS3_4100 also work
on other MIPS3 CPUs.
XXX: now should we rename options MIPS3_4100 to options ENABLE_MIPS_R4100,
XXX: or just make MIPS3_PG_SHIFT always a variable?

nisimura | branches: 1.11.2;
Nuke MIPS_16K_PAGE conditional which should be commited in. It
was used for debugg'n purposes which only make senses on particular
hardware configurations and has never been intended to extend pagesize
of NetBSD/mips.

Changes for NetBSD/hpcmips.

Support CPU without FPU.
Fix virtual alias problem(physio() case).
[new options]
options MIPS3_4100 /* VR4100 core */

nisimura | - Change a symbolic name of TLB entrylo from 'PG_M' to 'PG_D' to reflect
processor design. MIPS 'dirty bit' is not the same as i386 'dirty bit'.
There is a growing concern of misuse in NetBSD/mips.

jonathan | branches: 1.8.10;
Changes to sys/arch/mips from ARC port, from Noriyuki Soda <soda@sra.co.jp>.
Adds (most) support for ARC platform to port-independent mips code.
Some changes (e.g., clean up of overlapping CPU/FPU ids) inspired by
comparison to the OpenBSD 2.1 codebase of Soda's ARC port.
Open issues:
* Still no support for r4600 or mipsIV CPUs with two-way L1 cache.
Code derived from Per Fogelstrom's OpenBSD source doesn't work
on mips3 pmaxes with L2 cache.
* Still some port-specific #ifdefs, for interrupt enable and
pmax L2 cache-size. Needs more thought, but overlaps with
work-in-progress by Tohru and Tsubai on spl()s and related stuff.

| 16-Jun-1997 |
jonathan | Changes for configuring both MIPS1 and MIPS3, from a merge of
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:
mips1 TLB bit definitions.
mips/include/mips3_pte.h:
mips3 TLB bit definitions.
mips/include/pte.h:
define accesor macros for TLB bits (e.g., mips_pg_m_bit(),
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.
|

| 15-Jun-1997 |
mhitch | More merged MIPS1/MIPS3 support. The pte definitions still need work before
they can be support both MIPS1 and MIPS3.
|
| 1.5 |
| 13-Oct-1996 |
jonathan | Add (missing) PAGE_IS_RDONLY() macro to test for readonly pages,
in both mips-I and mips-II versions, and use it in arch/mips/mips/trap.c.
|
| 1.4 |
| 13-Oct-1996 |
jonathan | Merge mips1 and mips3 pte/pmap code, pass 0;
* 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>.
|
| 1.3 |
| 11-Aug-1996 |
jonathan | * Apply LOCORE -> _LOCORE change so locore.S doesn't #include struct
definitions.
* Include <mips/cpuregs.h> in <cpu.h> so kern_clock.c has user/kernel
status bits in scope. Still needs work; r2k/r4k previous-mode bits
are different.
* Include <mips/mips_param.h> in pica/include/param.h, for locore declarations,
and definitions of vm and other constants that should be shared across
NetBSD/mips systems to esnsure user-level binary compatibility.

A i386 GENERIC kernel compiles without the siop, ahc and bha drivers

sparc/esp_sbus. alpha should work as well (untested yet).
