/trunk/kernel/arch/sparc64/
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
6402 d 9 h
jermar
/trunk/kernel/arch/sparc64/src/
Make the sparc64 kernel compile again.
2038
6403 d 4 h
jermar
/trunk/kernel/arch/sparc64/
Remove old stuff.
2037
6403 d 5 h
jermar
/trunk/kernel/arch/sparc64/include/
Backout change from revision 2034.
sparc64 is not yet ready for get_cycle().
2034
6403 d 13 h
jermar
/trunk/kernel/arch/sparc64/include/
get_cycle() for sparc64.
2025
6405 d 4 h
jermar
/trunk/
Coding style fixes.
2023
6405 d 7 h
decky
/trunk/kernel/arch/
add dummy cycle.h
2016
6405 d 14 h
jermar
/trunk/kernel/arch/sparc64/src/mm/
The D-cache line size is actually 32 bytes on UltraSPARC II, IIi (and also IIe).
2015
6407 d 7 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.
2010
6412 d 6 h
jermar
/trunk/kernel/arch/sparc64/src/mm/
Fix comment.
2009
6412 d 6 h
jermar
/trunk/kernel/
Initial support for handling illegal virtual aliases on sparc64.
2008
6414 d 7 h
jermar
/trunk/kernel/arch/sparc64/
Add dcache_flush() function that flushes D-Cache on sparc64.
2007
6415 d 5 h
jermar
/trunk/kernel/
Introduce page colors. So far, only sparc64 uses correct page color bits. Other architectures have a dummy define
specifying zero bits for a page color.
There is a new check of page color in as_area_share(). Because of lack of support for this in the userspace, the
check has been #ifef'ed out.
2003
6416 d 12 h
decky
/trunk/kernel/arch/
cleanup endian conversion macros
2001
6418 d 4 h
jermar
/trunk/kernel/
Indentation and comment fixes.
1996
6424 d 9 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.
1994

Add BGR 0888 visual for Ultra 60
1993

make framebuffer code more generic
1988
6426 d 5 h
jermar
/trunk/kernel/arch/sparc64/src/mm/
Update comment and move initialization code away from application processor codepath.
1987
6426 d 8 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.
1986
6426 d 11 h
decky
/trunk/kernel/arch/sparc64/src/drivers/
The FFB framebuffer looks more like 32b
1984
6427 d 7 h
jermar
/trunk/kernel/arch/sparc64/
sparc64 work:
- untested support for Psycho PCI controller
1983
6428 d 11 h
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
6428 d 14 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
6429 d 7 h
jermar
/trunk/
sparc64 code to support physical memory that starts on non-zero addresses.
Still needs to be tested on systems with such setup.
1977
6430 d 3 h
jermar
/trunk/
Fix bad indentation in ofw.c
sparc64 work:
o Fix copyright in main.c
o Move code from unused parts of the trap table.
1976
6435 d 12 h
jermar
/trunk/kernel/arch/sparc64/
sparc64 context does not have to include the CLEANWIN register.
1975

Typo.
1960

Fix the following bug:
Ticket #3 data_access_exception after killing task on sparc64

Minor changes. Some coding style fixes and also a type (tee vs. tree).
One AS -> as change.
1949
6455 d 14 h

Remove notes about automatically generated context_offset.h
and replace it with a proper copyright notice.

Remove broken, outdated and unused gencontext.c utilities.
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.

Add support for IPC notifications even for polled ns16550 based keyboard.
1923
6461 d 6 h
jermar

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
6462 d 14 h

More IRQ stuff.
Modify the IRQ hash table functions to support lookup based on inr and devno.
Add method member to irq_t.
1921
6463 d 8 h
jermar
/trunk/kernel/
Changes in ns16550 and z8530 drivers.
Add some stuff for IRQ notifications to irq_t.

6463 d 16 h
jermar
/trunk/kernel/
Move the new IRQ redirector to ddi/.
Add function for assigning unique device numbers.
Change sparc64/drivers/kbd.c to assign devno to keyboard.
1919
6464 d 6 h
jermar
/trunk/kernel/
Prototypical implementation of new IRQ redirector in sparc64.
The new code can support shared IRQs in kernel (and multiple IRQs per device).
Userspace support is yet to be written.
The only architecture that uses this code is actually sparc64 only.
