2307 6441 d 20 h hudecek /branches/rcu/ Updated branch to latest trunk revision  
2292 6450 d 8 h hudecek /branches/rcu/ updated to latest trunk revision, minor tweaks in tasklet.c  
2131 6485 d 1 h decky /branches/ add development branches  
2126 6525 d 19 h decky /trunk/kernel/ small cleanup, more work coming  
2125 6525 d 22 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2106 6534 d 4 h jermar /trunk/kernel/ Merge as_t structure into one and leave the differring parts in as_genarch_t.

Indentation and formatting changes in header files.
 
2094 6539 d 0 h decky /trunk/kernel/generic/ avoid conflict with potential keyword  
2089 6540 d 4 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2087 6541 d 0 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2071 6550 d 21 h jermar /trunk/ (c) versus (C)  
2069 6552 d 20 h jermar /trunk/ Improve formatting.  
2015 6589 d 21 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 6594 d 21 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2007 6597 d 20 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.
 
1954 6633 d 20 h jermar /trunk/ Minor changes. Some coding style fixes and also a type (tee vs. tree).
One AS -> as change.
 
1915 6651 d 22 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 6652 d 3 h jermar /trunk/kernel/generic/ Add function for printing out info about address space.  
1891 6671 d 20 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).
 
1890 6672 d 6 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 6672 d 22 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
