2170 6249 d 14 h jermar /trunk/kernel/ Simplify synchronization in as_switch().
The function was oversynchronized, which
was causing deadlocks on the address
space mutex.

Now, address spaces can only be switched
when the asidlock is held. This also protects
stealing of ASIDs. No other synchronization
is necessary.		  
2125 6297 d 16 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2089 6311 d 23 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2083 6317 d 22 h decky /trunk/kernel/ typedef elimination  
2079 6318 d 17 h decky /trunk/kernel/ remove some typedefs in favor of anonymous structures  
2071 6322 d 15 h jermar /trunk/ (c) versus (C)  
2057 6350 d 3 h jermar /trunk/kernel/arch/ Fix all remaining mistmatches in width of byte swapping functions for ia64,
ppc32, ppc64, amd64, mips32 and ia32.		  
2023 6359 d 16 h decky /trunk/kernel/arch/ add dummy cycle.h  
2007 6369 d 14 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.		  
2003 6370 d 20 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
1993 6378 d 23 h decky /trunk/ make framebuffer code more generic  
1949 6409 d 23 h jermar /trunk/kernel/arch/ Remove notes about automatically generated context_offset.h
and replace it with a proper copyright notice.		  
1948 6410 d 2 h jermar /trunk/kernel/ Remove broken, outdated and unused gencontext.c utilities.  
1930 6414 d 20 h decky /trunk/kernel/arch/ppc64/ ppc64: make it compile again  
1901 6435 d 21 h jermar /trunk/kernel/ Make SMP related parts of main.c more generic.
Move initialization of local APIC to architecture specific code.
Add arch_post_cpu_init() to support the above.		  
1891 6443 d 14 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1890 6444 d 0 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 6444 d 16 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 6447 d 19 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1882 6448 d 23 h jermar /trunk/kernel/ Support for sparc64 FPU context.
