Beat the implicit illegal virtual alias created by reusing userspace frames.
In the anonymous and ELF backends, if the architecture has virtually indexed D-cache,
selectively flush cachelines belonging to the frame being freed.
This fixes Ticket #20.

Formatting and indentation changes.

/trunk/kernel/arch/sparc64/src/mm/
The D-cache line size is actually 32 bytes on UltraSPARC II, IIi (and also IIe).
2015
6510 d 9 h
jermar
/trunk/
Rework support for virtually indexed cache.
Instead of repeatedly flushing the data cache, which was a huge overkill, refuse to create an illegal address alias
in the kernel (again) and allocate appropriate page color in userspace instead. Extend the detection also to
SYS_PHYSMEM_MAP syscall.
Add support for tracking physical memory areas mappable by SYS_PHYSMEM_MAP.
Lots of coding style changes.

Fix comment.
2009
6515 d 8 h
jermar
/trunk/kernel/
Initial support for handling illegal virtual aliases on sparc64.
2008
6517 d 9 h
jermar
/trunk/kernel/arch/sparc64/
Add dcache_flush() function that flushes D-Cache on sparc64.
2001
6521 d 6 h
jermar
/trunk/kernel/
Indentation and comment fixes.
1996
6527 d 10 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.
1988
6529 d 7 h
jermar
/trunk/kernel/arch/sparc64/src/mm/
Update comment and move initialization code away from application processor codepath.
1987
6529 d 10 h
jermar
/trunk/kernel/arch/sparc64/src/
Take the possible difference between kernel and physical address into account in TSB and userspace window buffer
allocation and deallocation code.
1983
6531 d 13 h

/trunk/kernel/arch/sparc64/src/mm/
sparc64 work:
- fix computation of the frame allocator configuration frame
- mark the first physical frame unavailable, no matter what is its address
Because of that, we can now boot past the frame_arch_init() on the Ultra 60 now.
1982
6531 d 16 h
jermar
/trunk/
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.
1960
6553 d 8 h
jermar
/trunk/kernel/arch/sparc64/src/mm/
Fix the following bug:
Ticket #3 data_access_exception after killing task on sparc64
1946

sparc64 work.
- Improve panic screen on data_access_exception
by dumping contents of DSFSR and DSFAR.
- Change the FHC enable interrupt code to only
set the IMAP_V bit.
1918
6571 d 8 h
jermar
/trunk/kernel/arch/sparc64/src/mm/
Omitted comma.
1917
6571 d 10 h
jermar
/trunk/
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 fixes.
The sparc64 kernel now compiles again even if not compiled with SMP support.
1903
6583 d 9 h
jermar
/trunk/
SMP stuff for sparc64.
Almost complete except for IPIs.
The absence of IPI support deadlocks
the kernel when more CPUs are configured.
