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.

sparc64 work:
- No need to lock kernel stack and userspace window buffer into DTLB.

Fix important comment in kernel/arch/sparc64/src/proc/scheduler.c.
Improve framebuffer code.
Formatting and indentation fixes.

On sparc64's tick interrupt, adjust the TICK_COMPARE register instead of the TICK
register. The TICK register now increments linearily and can be used by the get_cycle()
function.
2043

Make the sparc64 kernel compile again.

Remove old stuff.

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

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.

Initial support for handling illegal virtual aliases on sparc64.
2008
6440 d 2 h
jermar

Add dcache_flush() function that flushes D-Cache on sparc64.
2001
6443 d 23 h
jermar
/trunk/kernel/
Indentation and comment fixes.
1996
6450 d 3 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.

Update comment and move initialization code away from application processor codepath.
1987

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.

The FFB framebuffer looks more like 32b

sparc64 work:
- untested support for Psycho PCI controller

jermar
/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
6454 d 9 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.
1978

sparc64 code to support physical memory that starts on non-zero addresses.
Still needs to be tested on systems with such setup.
1977
6455 d 22 h
jermar

Fix bad indentation in ofw.c
sparc64 work:
o Fix copyright in main.c
o Move code from unused parts of the trap table.

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.

Add support for IPC notifications even for polled ns16550 based keyboard.
1923

Replace the old IRQ dispatcher and IPC notifier with new implementation.
Note that all architectures except for sparc64 are now broken
and don't even compile.
1922

More IRQ stuff.
Modify the IRQ hash table functions to support lookup based on inr and devno.
Add method member to irq_t.

Change sparc64/drivers/kbd.c to assign devno to keyboard.
