2170 6279 d 6 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 6327 d 9 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2110 6334 d 8 h jermar /trunk/kernel/arch/ia64/ Minor cleanup in ia64.  
2107 6335 d 7 h jermar /trunk/ When clock() is called by an external interrupt dispatched by the IRQ dispatcher,
no spinlock can be held or the kernel will not be preemptive. This fixes Ticket #24.

Formating and indentation fixes.
 
2089 6341 d 15 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2083 6347 d 15 h decky /trunk/kernel/ typedef elimination  
2082 6347 d 15 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2079 6348 d 10 h decky /trunk/kernel/ remove some typedefs in favor of anonymous structures  
2071 6352 d 8 h jermar /trunk/ (c) versus (C)  
2065 6366 d 6 h jermar /trunk/kernel/ Coding style fixes and formatting improvements.  
2064 6366 d 7 h vana /trunk/ SIMICS added as a simulator kernel runs on  
2060 6370 d 17 h jermar /trunk/kernel/arch/ia64/src/ Fix typo.  
2057 6379 d 19 h jermar /trunk/kernel/arch/ Fix all remaining mistmatches in width of byte swapping functions for ia64,
ppc32, ppc64, amd64, mips32 and ia32.
 
2023 6389 d 9 h decky /trunk/kernel/arch/ add dummy cycle.h  
2007 6399 d 6 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 6400 d 13 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
1945 6442 d 11 h jermar /trunk/kernel/arch/ia64/ ia64 work.
Move keyboard polling to a dedicated kernel thread.
Console initialization and console related sysinfo setup
can be now done in a single function.
 
1944 6442 d 11 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.
 
1942 6443 d 8 h jermar /trunk/ Convert ia64 to the new IRQ and notification scheme.  
1937 6443 d 19 h decky /trunk/kernel/arch/ remove orphaned functions
