2044 6374 d 1 h jermar /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.
 
2038 6374 d 20 h jermar /trunk/kernel/arch/sparc64/ Remove old stuff.  
2037 6374 d 20 h jermar /trunk/kernel/arch/sparc64/include/ Backout change from revision 2034.
sparc64 is not yet ready for get_cycle().
 
2034 6375 d 4 h jermar /trunk/kernel/arch/sparc64/include/ get_cycle() for sparc64.  
2025 6376 d 20 h jermar /trunk/ Coding style fixes.  
2023 6376 d 23 h decky /trunk/kernel/arch/ add dummy cycle.h  
2015 6378 d 22 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.
 
2009 6383 d 22 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6385 d 23 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
2007 6386 d 21 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 6388 d 3 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
1984 6398 d 23 h jermar /trunk/kernel/arch/sparc64/ sparc64 work:
- untested support for Psycho PCI controller
 
1978 6400 d 22 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.
 
1976 6407 d 4 h jermar /trunk/kernel/arch/sparc64/ sparc64 context does not have to include the CLEANWIN register.  
1954 6422 d 21 h jermar /trunk/ Minor changes. Some coding style fixes and also a type (tee vs. tree).
One AS -> as change.
 
1949 6427 d 6 h jermar /trunk/kernel/arch/ Remove notes about automatically generated context_offset.h
and replace it with a proper copyright notice.
 
1948 6427 d 8 h jermar /trunk/kernel/ Remove broken, outdated and unused gencontext.c utilities.  
1946 6429 d 20 h 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.
 
1942 6430 d 22 h jermar /trunk/ Convert ia64 to the new IRQ and notification scheme.  
1921 6434 d 23 h jermar /trunk/kernel/ Changes in ns16550 and z8530 drivers.
Add some stuff for IRQ notifications to irq_t.
