Tagging 0.2.0.4 release.

huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes

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.

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.

The D-cache line size is actually 32 bytes on UltraSPARC II, IIi (and also IIe).
2015
6490 d 21 h

/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

/trunk/kernel/
Initial support for handling illegal virtual aliases on sparc64.
2008
6497 d 21 h
jermar
/trunk/kernel/arch/sparc64/
Add dcache_flush() function that flushes D-Cache on sparc64.
2001
6501 d 18 h
jermar
/trunk/kernel/
Indentation and comment fixes.
1996
6507 d 23 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
6509 d 19 h
jermar
/trunk/kernel/arch/sparc64/src/mm/
Update comment and move initialization code away from application processor codepath.
1987
6509 d 22 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

/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
6512 d 5 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
6533 d 21 h
jermar
/trunk/kernel/arch/sparc64/src/mm/
Fix the following bug:
Ticket #3 data_access_exception after killing task on sparc64
1946

jermar
/trunk/kernel/arch/sparc64/
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.
