2089 6329 d 16 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2085 6335 d 15 h decky /trunk/kernel/ typedef elimination  
2083 6335 d 16 h decky /trunk/kernel/ typedef elimination  
2071 6340 d 9 h jermar /trunk/ (c) versus (C)  
2059 6363 d 18 h jermar /trunk/kernel/generic/ Improve indentation and formatting.  
2015 6379 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.
 
2009 6384 d 8 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2007 6387 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.
 
2001 6390 d 6 h jermar /trunk/kernel/ Indentation and comment fixes.  
2000 6390 d 18 h decky /trunk/kernel/ move files to more proper locations  
1999 6390 d 19 h decky /trunk/ start RAM disk support  
1951 6427 d 11 h jermar /trunk/kernel/generic/include/mm/ Fix comma mistakenly removed in last commit.  
1950 6427 d 12 h jermar /trunk/kernel/ Indentation changes and coding style fixes in slab.c and slab.h.  
1941 6431 d 12 h decky /trunk/kernel/generic/include/ cleanup  
1914 6441 d 15 h jermar /trunk/kernel/generic/ Add function for printing out info about address space.  
1891 6461 d 7 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).
 
1890 6461 d 18 h jermar /trunk/ - Create a dedicated slab cache for as_t objects and switch from malloc/free to slab_alloc/slab_free for
them.

- Slightly fix and improve both the kernel and userspace atomic_add() on sparc64.

- More TSB work on the sparc64 front.
 
1889 6462 d 9 h jermar /trunk/kernel/ Fix bug in mm/as.c:
- as_area_destroy() should not work with AS but as

sparc64 work:
- start implementing TSB support
 
1888 6465 d 12 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1868 6474 d 15 h jermar /trunk/ sparc64 work.
- the syscall wrapper needs to use the "memory"
clobber specifier to prevent over-optimization.
- on sparc64, the user address space spans the whole
64-bit space and therefore the macro
USER_ADDRESS_SPACE_SIZE_ARCH, as it was defined,
overflows to 0
- stop using USER_ADDRESS_SPACE_SIZE_ARCH and define
MAX_HEAP_SIZE instead
- in our situation when kernel and user address spaces
are separate, the G (global) bit cannot be used
(there is no point in it anymore)
- add the DEBUG() macro to stdio.h; DEBUG() uses
SYS_IO and is a good debugging tool for getting
early userspace to work
