2307 6940 d 5 h hudecek /branches/rcu/ Updated branch to latest trunk revision  
2292 6948 d 18 h hudecek /branches/rcu/ updated to latest trunk revision, minor tweaks in tasklet.c  
2131 6983 d 10 h decky /branches/ add development branches  
2126 7024 d 4 h decky /trunk/kernel/ small cleanup, more work coming  
2125 7024 d 7 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2106 7032 d 14 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 7037 d 9 h decky /trunk/kernel/generic/ avoid conflict with potential keyword  
2089 7038 d 14 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2087 7039 d 9 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2071 7049 d 6 h jermar /trunk/ (c) versus (C)  
2069 7051 d 5 h jermar /trunk/ Improve formatting.  
2015 7088 d 7 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 7093 d 6 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2007 7096 d 5 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 7132 d 5 h jermar /trunk/ Minor changes. Some coding style fixes and also a type (tee vs. tree).
One AS -> as change.
 
1915 7150 d 7 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 7150 d 12 h jermar /trunk/kernel/generic/ Add function for printing out info about address space.  
1891 7170 d 5 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).
 
1890 7170 d 15 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 7171 d 7 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
