bouyer | loongson2f support:
- Add some loongson2 definitions to cpuregs.h, from OpenBSD
- Make sure that the at register is useable before every jump register
instruction (exept when register is k0 or k1) because -mfix-loongson2f-btb
needs the at register for its workaround
- add code to mips_fixup.c to handle the instructions added by
-mfix-loongson2f-btb
- Add a ls2-specific tlb miss handler: it doesn't have separate handler
for the xtlbmiss exeption.

pooka | Add support for the Extensible MIPS ("eMIPS") platform. The
NetBSD/emips port runs on Xilinx and Beecube FPGA systems and the
Giano system simulator.
eMIPS is a platform developed at Microsoft Research for researching
reconfigurable computing. eMIPS allows dynamic loading and scheduling
of application-specific circuits for the purpose of accelerating
computations based on the current workload.
NetBSD eMIPS support for NetBSD 4.x was written at Microsoft Research
by Alessandro Forin and Neil Pittman. Microsoft Corporation has
donated full copyright to The NetBSD Foundation.
Platform support for eMIPS is the first part of Microsoft's
contribution. The second part includes the hardware accelerator
framework and will be proposed on tech-kern soon.

garbled | 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.

Change MIPS3_SR_FR_32 to MIPS3_SR_FR. Both the old R4000 manual and the
current MIPS64 manuals don't use the "32" in the bit name.
|

MIPS_COP_0_CAUSE_REG - use MIPS_COP_0_STATUS and MIPS_COP_0_CAUSE
instead.
|
| 1.59 |
| 10-Jan-2003 |
rafal | Add the MIPS3_CONFIG_SE (name taken from Rm52xx manual) bit, which is the
external cache enable bit -- this allows software to enable or disable the
(external) L2 cache on the R5k and Rm527x and the (external) L3 cache on
the Rm7k. If the (external) cache is disabled, treat it as if there were
no cache for the purposes of the cache setup code.
Also, update sgimips code to use the new name.

- 0x55 for NEC Vr5500. ISA might be MIPS64.
- 0x38 for Toshiba TX79. This has thirty-two 128bit GPRs while
maintaining 32bit only virtual address space. Any of pointer related

simonb | Add support for detecting Alchemy Semiconductor CPUs. Alchemy use the
processor ID field to donote the CPU core revision and the company
options field do donate the SOC chip type, so we need to add an extra
field to the "pridtab" structure to identify these CPUs.
|

gmcgarry | Overhaul the emulation facility. We do this by:
- accumulating all emulation code (including floating-point) in one place
- steal MachFPInterrupt() back from SOFTFLOAT for use only with interrupts
and traps from *real* FPUs
- introducing MachEmulateInst() as a common dispatch point for all
emulated instructions
- cleaning up emulation dispatch in trap()
Also, while we're here, implement MIPS2 LL/SC/SYNC emulation for MIPS1.
Tested on r3k with and without SOFTFLOAT enabled.

R5900 support.
COP0_SYNC
In R5900 mtc0, tlbr, tlbp, tlbwi, tlbwr must be followed by sync.p.
if defined MIPS3_5900, COP0_SYNC is defined as sync.p. else nothing.
IPL_ICU_MASK
mask interrupt directly ICU instead of SR.IM.
I've added this feature to support software interrupt for R5900.

chuck | IDT32364's Config register uses a different base for IC/DC (instruction
and data cache sizes). R4000 uses 2^(12+IC) and 2^(12+DC). IDT32364
uses 2^(9+IC) and 2^(9+DC).
abstract around the problem by making the base a parameter to the
MIPS3_CONFIG_CACHE_SIZE macro. we pass the base down from mips_vector_init
to mips3_vector_init and to mips3_ConfigCache (where it is used).
XXX: someone with an MIPS3_4100 should switch to this and get rid
of the ugly ifdefs in cpuregs.h

More patches for ARC from Noriyuki Soda:
* commit isapnpvar.h changes required for ARC to support plain isa.
* fixup mistake over mips/include/cpuregs.h.
* mips/mips_machdep.c:
set L2 cache-size for arc, cleanup use of L2cache present
vs L2 cache-size variables. check for no L2 cache on kernels
configured to require one. misc cleanups.
* mips/mpis/trap.c: more locore stack-traceback label cleanup.

jonathan | 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.

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
to break them out at the caller anyway.
* Add compile-time MIPS3-only andcompile-time MIPS1-only
macros to call locore functions directly by name.
Use the existing method table only if
* mips/mips_machdep.c, mips/trap.c, mips/pmap.c, pmax/machdep.c:
Use MIPS3_ or MIPS1_ specific names for TLB pids in
mips3 and mips1 specific code paths (e.g., creating the kernel stack
for process 0).
Add `options MIPS3' to pmax/conf/GENERIC.

jonathan | More mips1/mips3 changes to cpuregs.h and psl.h:
* 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,
mips3 only, or when both are defined, use runtime CPUISMIPS3 test.

jonathan | Resolve all differences between the Pica and pmax versions of machConst.h:
* add "MIPS_3k_" for the MIPS-I r[23]000-specific register definitions.
* add "MIPS_4k_" for the MIPS-II/III r4000-specific register definitions.
* add #defines that provide the old values for locore and user
code, so the existing code continues to compile.
Regression-tested against the old headers by grepping for #define's,
editing out the defined symbols, and preprocessing with both the previous
machConst.h headers and this version.
Some unused symbols (CPU and FPU must-be-zero constants) are no longer defined.
Pica interrupt masks are now constant expressions instead of constant
values.
TODO:
* factor out the common #defines into src/sys/arch/mips.
* Get rid of the Sprite coding-style names (MACH_xxx).
* Separate out the r3k/r4k differences from the Pica/pmax differences.
* Figure out how to have a run-time choice of r3k vs. r4k support,
instead of a compile-time choice.

matt | Add initial support for XLP II (XLP2XX/XLP1XX).
|
| 1.74.28.25 |
| 19-Jan-2012 |
matt | When running an N32 kernel, run it with 64-bit addresses even though the
kernel itself will only use 32-bit addresses. There are exceptions.
bus_space_handles are now register_t instead of intptr_t. This allows them
to contain XKPHYS addresses. Now bus_space can use XKPHYS addresses and
not required non-KSEG1 devices to be mapped in KSEG2 thereby leaving more
KSEG2 space for the kernel to use.
The cache range routines (but not index routines) now take a register_t
instead of vaddr_t so they can too take a XKPHYS address. This allows the
pmap to use a page's XKPHYS address to clean sync the icache thereby avoiding
massive icache invalidations.
Since "cache" instruction effects are global to all CPUs and their caches, we
can use the above to greatly simplify MP page isyncs. If using an O32 kernel
with pages outside KSEG0, index ops still need to be performed since there
isn't an a quick way of mapping the page.

| 26-May-2011 |
matt | Add MIPS64_RMIXL (XLR/XLS) and MIPS64R2_RMIXL (XLP). This allows the kernel
to treat this special which is needed for MP support. When accessing the TLB,
always lock the TLB before hand. If in the miss handlers, the TLB is already
locked let trap deal with the exeception.
|
| 1.74.28.20 |
