2019 6380 d 11 h decky /trunk/kernel/ prepare for new test infrastructure  
2018 6380 d 12 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2017 6380 d 15 h decky /trunk/kernel/arch/ia32xen/ update for Xen  
2016 6380 d 16 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 6382 d 9 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 6384 d 11 h decky /trunk/ version bump to Xen 3.0.3 (not fully operational yet)  
2012 6385 d 7 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 6386 d 13 h decky /trunk/kernel/ resolve ticket #4  
2010 6387 d 8 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix comment.  
2009 6387 d 8 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6389 d 9 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
2007 6390 d 7 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 6391 d 14 h decky /trunk/ update rd  
2004 6391 d 14 h decky /trunk/kernel/generic/include/ cleanup  
2003 6391 d 14 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
2002 6391 d 16 h decky /trunk/kernel/generic/ rd work  
2001 6393 d 6 h jermar /trunk/kernel/ Indentation and comment fixes.  
2000 6393 d 18 h decky /trunk/kernel/ move files to more proper locations  
1999 6393 d 18 h decky /trunk/ start RAM disk support  
1996 6399 d 11 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 6399 d 11 h jermar /trunk/kernel/ Move general configuration out of debugging configuration.
Add CONFIG_VIRT_IDX_CACHE.		  
1994 6399 d 16 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6399 d 17 h decky /trunk/ make framebuffer code more generic  
1991 6400 d 10 h jermar /trunk/kernel/genarch/src/fb/ The prefered switch statement indentation is the one replaced by the previous commit :-)  
1990 6400 d 13 h decky /trunk/kernel/genarch/src/fb/ framebuffer cleanup  
1988 6401 d 7 h jermar /trunk/kernel/arch/sparc64/src/mm/ Update comment and move initialization code away from application processor codepath.  
1987 6401 d 10 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 6401 d 14 h decky /trunk/kernel/arch/sparc64/src/drivers/ The FFB framebuffer looks more like 32b  
1985 6401 d 14 h decky /trunk/kernel/ add benchmarking configuration directive  
1984 6402 d 9 h jermar /trunk/kernel/arch/sparc64/ sparc64 work:
- untested support for Psycho PCI controller		  
1983 6403 d 13 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 6403 d 17 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 6403 d 17 h jermar /trunk/kernel/ Indentation, formatting and minor changes.  
1980 6403 d 18 h jermar /trunk/kernel/arch/mips32/include/mm/ mips32 mm has not been under construction for while now  
1979 6404 d 8 h jermar /trunk/ Configuration changes on sparc64.
Compile TSB support by default.
Ask whether to start AP processors in the loader.		  
1978 6404 d 9 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 6405 d 6 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 6410 d 15 h jermar /trunk/kernel/arch/sparc64/ sparc64 context does not have to include the CLEANWIN register.  
1975 6414 d 7 h jermar /trunk/kernel/arch/sparc64/src/ Typo.  
1974 6414 d 11 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.
