2170 6397 d 1 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.		  
2110 6452 d 3 h jermar /trunk/kernel/arch/ia64/ Minor cleanup in ia64.  
2107 6453 d 2 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 6459 d 10 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2082 6465 d 11 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6470 d 3 h jermar /trunk/ (c) versus (C)  
2065 6484 d 1 h jermar /trunk/kernel/ Coding style fixes and formatting improvements.  
2064 6484 d 2 h vana /trunk/ SIMICS added as a simulator kernel runs on  
2060 6488 d 12 h jermar /trunk/kernel/arch/ia64/src/ Fix typo.  
1945 6560 d 6 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 6560 d 6 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.		  
1942 6561 d 3 h jermar /trunk/ Convert ia64 to the new IRQ and notification scheme.  
1937 6561 d 14 h decky /trunk/kernel/arch/ remove orphaned functions  
1901 6583 d 9 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.		  
1888 6595 d 7 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1882 6596 d 10 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1881 6597 d 11 h jermar /trunk/ sparc64 work:
- find a CPU node and read its clock_frequency attribute
- implement asm_delay_loop()
- set TICK_COMPARE register according to processor frequency
- small improvements at random places

OpenFirmware work:
- two new functions for walking the device tree

Generic boot loader work:
- added basic string functions

Usual pile of indentation and formatting fixes.		  
1877 6600 d 14 h jermar /trunk/kernel/ Coding style fixes.
Remove unneeded sparc64 dummy functions.		  
1851 6619 d 10 h jermar /trunk/kernel/ sparc64 work.
Define the istate structure.
Move the identity-mapping handler to assembly.
Make the preemptible handler more general so that TL=1 MMU exceptions can make use of it.

Little bit of formatting and indentation.		  
1850 6622 d 13 h jermar /trunk/kernel/arch/ia64/src/mm/ Indentation and formatting changes.
