2015 6428 d 10 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.		  
2014 6430 d 12 h decky /trunk/ version bump to Xen 3.0.3 (not fully operational yet)  
2012 6431 d 8 h jermar /trunk/ Eliminate confusion between SYS_MAP_PHYSMEM and sys_physmem_map.
The syscall is to be called SYS_PHYSMEM_MAP from now on and the functions that participate in its implementation are
called *physmem_map().		  
2011 6432 d 14 h decky /trunk/kernel/ resolve ticket #4  
2010 6433 d 9 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix comment.  
2009 6433 d 9 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6435 d 10 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
2007 6436 d 8 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.		  
2005 6437 d 15 h decky /trunk/ update rd  
2004 6437 d 15 h decky /trunk/kernel/generic/include/ cleanup  
2003 6437 d 15 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
2002 6437 d 17 h decky /trunk/kernel/generic/ rd work  
2001 6439 d 7 h jermar /trunk/kernel/ Indentation and comment fixes.  
2000 6439 d 19 h decky /trunk/kernel/ move files to more proper locations  
1999 6439 d 19 h decky /trunk/ start RAM disk support  
1996 6445 d 12 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.		  
1995 6445 d 12 h jermar /trunk/kernel/ Move general configuration out of debugging configuration.
Add CONFIG_VIRT_IDX_CACHE.		  
1994 6445 d 17 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6445 d 18 h decky /trunk/ make framebuffer code more generic  
1991 6446 d 11 h jermar /trunk/kernel/genarch/src/fb/ The prefered switch statement indentation is the one replaced by the previous commit :-)  
1990 6446 d 14 h decky /trunk/kernel/genarch/src/fb/ framebuffer cleanup  
1988 6447 d 8 h jermar /trunk/kernel/arch/sparc64/src/mm/ Update comment and move initialization code away from application processor codepath.  
1987 6447 d 11 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 6447 d 14 h decky /trunk/kernel/arch/sparc64/src/drivers/ The FFB framebuffer looks more like 32b  
1985 6447 d 15 h decky /trunk/kernel/ add benchmarking configuration directive  
1984 6448 d 10 h jermar /trunk/kernel/arch/sparc64/ sparc64 work:
- untested support for Psycho PCI controller		  
1983 6449 d 14 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 6449 d 18 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.		  
1981 6449 d 18 h jermar /trunk/kernel/ Indentation, formatting and minor changes.  
1980 6449 d 19 h jermar /trunk/kernel/arch/mips32/include/mm/ mips32 mm has not been under construction for while now  
1979 6450 d 9 h jermar /trunk/ Configuration changes on sparc64.
Compile TSB support by default.
Ask whether to start AP processors in the loader.		  
1978 6450 d 10 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 6451 d 7 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 6456 d 16 h jermar /trunk/kernel/arch/sparc64/ sparc64 context does not have to include the CLEANWIN register.  
1975 6460 d 8 h jermar /trunk/kernel/arch/sparc64/src/ Typo.  
1974 6460 d 12 h jermar /trunk/kernel/genarch/src/ofw/ Rewrite OFW device tree traversal algorithms to iterate over the list of peers rather than recurse on each
peer node. This saves us from big troubles with stack overflows.		  
1972 6462 d 16 h jermar /trunk/ Modify selected function to consume less stack space.

Avoid flushw instruction in the sparc64 loader.		  
1970 6469 d 18 h decky /trunk/kernel/arch/ia32/src/smp/ use new IRQ scheme in l_apic_timer_interrupt()  
1960 6471 d 10 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix the following bug:

Ticket #3 data_access_exception after killing task on sparc64		  
1959 6471 d 16 h decky /trunk/kernel/arch/ia32xen/src/ ia32xen: adopt new IRQ interface
