2089 6319 d 8 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2087 6320 d 3 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2083 6325 d 7 h decky /trunk/kernel/ typedef elimination  
2076 6328 d 9 h jermar /trunk/kernel/ Beat the implicit illegal virtual alias created by reusing userspace frames.
In the anonymous and ELF backends, if the architecture has virtually indexed D-cache,
selectively flush cachelines belonging to the frame being freed.
This fixes Ticket #20.
 
2071 6330 d 0 h jermar /trunk/ (c) versus (C)  
2069 6331 d 23 h jermar /trunk/ Improve formatting.  
2059 6353 d 9 h jermar /trunk/kernel/generic/ Improve indentation and formatting.  
2052 6359 d 4 h decky /trunk/kernel/generic/src/mm/ pretty-print slabs  
2048 6362 d 2 h jermar /trunk/ Formatting and indentation changes.  
2035 6365 d 6 h decky /trunk/kernel/generic/src/ more fancy kconsole output  
2015 6369 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.
 
2009 6374 d 0 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2007 6376 d 23 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.
 
2000 6380 d 10 h decky /trunk/kernel/ move files to more proper locations  
1999 6380 d 10 h decky /trunk/ start RAM disk support  
1981 6390 d 8 h jermar /trunk/kernel/ Indentation, formatting and minor changes.  
1954 6412 d 23 h jermar /trunk/ Minor changes. Some coding style fixes and also a type (tee vs. tree).
One AS -> as change.
 
1950 6417 d 3 h jermar /trunk/kernel/ Indentation changes and coding style fixes in slab.c and slab.h.  
1915 6431 d 1 h jermar /trunk/kernel/ A quote from from SPARC V9 specification:

The Y register is deprecated; it is provided only for compatibility with previous versions
of the architecture. It should not be used in new SPARC-V9 software. It is
recommended that all instructions that reference the Y register (i.e., SMUL,
SMULcc, UMUL, UMULcc, MULScc, SDIV, SDIVcc, UDIV, UDIVcc, RDY, and
WRY) be avoided. See the appropriate pages in Appendix A, “Instruction Definitions,”
for suitable substitute instructions.

Still gcc is generating code which uses Y and some of the instructions above.
This change modifies the preemptible_handler() to preserve the Y register
across preemption.
 
1914 6431 d 6 h jermar /trunk/kernel/generic/ Add function for printing out info about address space.
