2015 6500 d 1 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 6502 d 3 h decky /trunk/ version bump to Xen 3.0.3 (not fully operational yet)  
2013 6502 d 3 h decky /trunk/boot/arch/ bump to GRUB version 0.97  
2012 6502 d 23 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 6504 d 6 h decky /trunk/kernel/ resolve ticket #4  
2010 6505 d 0 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix comment.  
2009 6505 d 1 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6507 d 2 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
2007 6508 d 0 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.		  
2006 6509 d 6 h decky /trunk/uspace/ start trivial file system driver  
2005 6509 d 6 h decky /trunk/ update rd  
2004 6509 d 6 h decky /trunk/kernel/generic/include/ cleanup  
2003 6509 d 6 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
2002 6509 d 8 h decky /trunk/kernel/generic/ rd work  
2001 6510 d 23 h jermar /trunk/kernel/ Indentation and comment fixes.  
2000 6511 d 11 h decky /trunk/kernel/ move files to more proper locations  
1999 6511 d 11 h decky /trunk/ start RAM disk support  
1998 6515 d 2 h decky /trunk/boot/arch/ add version tag to other bootloaders  
1997 6515 d 2 h decky /trunk/ add version to init and boot loader  
1996 6517 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.		  
1995 6517 d 3 h jermar /trunk/kernel/ Move general configuration out of debugging configuration.
Add CONFIG_VIRT_IDX_CACHE.		  
1994 6517 d 8 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6517 d 9 h decky /trunk/ make framebuffer code more generic  
1992 6517 d 10 h decky /trunk/uspace/libc/include/ add bool.h  
1991 6518 d 2 h jermar /trunk/kernel/genarch/src/fb/ The prefered switch statement indentation is the one replaced by the previous commit :-)  
1990 6518 d 5 h decky /trunk/kernel/genarch/src/fb/ framebuffer cleanup  
1989 6518 d 7 h decky /trunk/boot/arch/sparc64/loader/ remove disasm on clean  
1988 6518 d 23 h jermar /trunk/kernel/arch/sparc64/src/mm/ Update comment and move initialization code away from application processor codepath.  
1987 6519 d 2 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 6519 d 6 h decky /trunk/kernel/arch/sparc64/src/drivers/ The FFB framebuffer looks more like 32b  
1985 6519 d 6 h decky /trunk/kernel/ add benchmarking configuration directive  
1984 6520 d 2 h jermar /trunk/kernel/arch/sparc64/ sparc64 work:
- untested support for Psycho PCI controller		  
1983 6521 d 5 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 6521 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.		  
1981 6521 d 9 h jermar /trunk/kernel/ Indentation, formatting and minor changes.  
1980 6521 d 10 h jermar /trunk/kernel/arch/mips32/include/mm/ mips32 mm has not been under construction for while now  
1979 6522 d 0 h jermar /trunk/ Configuration changes on sparc64.
Compile TSB support by default.
Ask whether to start AP processors in the loader.		  
1978 6522 d 1 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 6522 d 22 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 6528 d 7 h jermar /trunk/kernel/arch/sparc64/ sparc64 context does not have to include the CLEANWIN register.
