Replace all deprecated BA (Bicc) instructions with BA %xcc instructions.

On sparc64, do fast indentity mapping only for physical memory.
For addresses above physical memory, such as I/O devices,
fall through to the C miss handler and map the memory noncacheably.
Replace deprecated Bicc instructions with proper Bcc instructions.

Merge sparc branch to trunk.

When invalidating entire TLBs on sparc64, make sure to also invalidate any (locked) global entries.
This fixes Ticket #21.
Fix a comment in start.S stating that the kernel installs a global entry for itself. All entries installed by the kernel
are local to some memory context.

Improve comments.

jermar
/trunk/kernel/arch/sparc64/src/
More formatting and indentation changes.
2009
6466 d 15 h
jermar
/trunk/kernel/
Initial support for handling illegal virtual aliases on sparc64.
2008
6468 d 16 h
jermar
/trunk/kernel/arch/sparc64/
Add dcache_flush() function that flushes D-Cache on sparc64.
2001
6472 d 13 h
jermar
/trunk/kernel/
Indentation and comment fixes.
1996
6478 d 17 h
jermar
/trunk/kernel/
Add option to compile the sparc64 kernel without the TTE_CV bit support.
The bit is not used by default now.
Enabling it may theoretically lead to physical memory inconsistencies until code that
mitigates the problem is written.

Modify the sparc64 startup code to not cause MMU traps before it takes over the TLB and
the trap table. Fix several PA2KA and KA2PA omittions or errors. Fix configuration to pass
the DEFS variable along.

sparc64 code to support physical memory that starts on non-zero addresses.
Still needs to be tested on systems with such setup.
1975
6493 d 14 h
jermar
/trunk/kernel/arch/sparc64/src/
Typo.
1954
6505 d 14 h
jermar
/trunk/
Minor changes. Some coding style fixes and also a type (tee vs. tree).
One AS -> as change.

sparc64 work:
- hw_map() can now support up to 8M requests
- CPU stacks are now locked in DTLB of the respective processor
- kernel in the boot phase no longer relies on the stack provided by OpenFirmware
- instead of of doing FLUSHW during kernel startup, simply set the
window state registers to the wanted state
- NWINDOW -> NWINDOWS
- Add/fix some comments and copyrights.

Small improvements in sparc64.
1905
6533 d 2 h
jermar
/trunk/kernel/arch/sparc64/src/
Small fixes.
The sparc64 kernel now compiles again even if not compiled with SMP support.
1903

/trunk/
SMP stuff for sparc64.
Almost complete except for IPIs.
The absence of IPI support deadlocks
the kernel when more CPUs are configured.

jermar
/trunk/kernel/arch/sparc64/src/
Block the secondary processors after they setup kernel mapping in ITLB and DTLB and
switch to kernel trap table.
