2719 5952 d 1 h decky /trunk/kernel/arch/mips32/src/ prettyprint bkpts command  
2696 5973 d 3 h decky /trunk/kernel/arch/mips32/ initial support for dorder device in MSIM  
2634 6017 d 11 h decky /trunk/kernel/arch/mips32/src/ fix trivial bug in storing lastcount  
2633 6017 d 11 h decky /trunk/kernel/arch/mips32/ CPU cycle accounting on MIPS  
2607 6032 d 20 h jermar /trunk/ Support for six syscall arguments on mips32.  
2232 6253 d 16 h decky /trunk/kernel/arch/mips32/src/ add support for halt/reboot in MSIM  
2227 6254 d 6 h decky /trunk/kernel/ start shutdown infrastructure  
2170 6262 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.		  
2107 6318 d 15 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 6324 d 23 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6335 d 16 h jermar /trunk/ (c) versus (C)  
1993 6392 d 0 h decky /trunk/ make framebuffer code more generic  
1955 6418 d 3 h decky /trunk/kernel/arch/mips32/ timer_fnc -> virtual_timer_fnc  
1944 6425 d 19 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.		  
1936 6427 d 2 h decky /trunk/kernel/arch/mips32/ mips32: update for new IRQ subsystem  
1901 6448 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.		  
1888 6460 d 19 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1882 6461 d 23 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1881 6462 d 23 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.		  
1837 6502 d 4 h jermar /trunk/ Support 24bpp framebuffers with 4 pixelbytes (each pixel aligned on 32-bits).

At least on sparc64, the OpenFirmware linebytes property specifies the number
of pixels between consecutive scan lines of the display. Fix scanilne calculation,
including possible alignment.

Add note to 8bpp pixel functions pointing out drawbacks of that mode.
