2719 5938 d 0 h decky /trunk/kernel/arch/mips32/src/ prettyprint bkpts command  
2696 5959 d 1 h decky /trunk/kernel/arch/mips32/ initial support for dorder device in MSIM  
2634 6003 d 10 h decky /trunk/kernel/arch/mips32/src/ fix trivial bug in storing lastcount  
2633 6003 d 10 h decky /trunk/kernel/arch/mips32/ CPU cycle accounting on MIPS  
2607 6018 d 18 h jermar /trunk/ Support for six syscall arguments on mips32.  
2232 6239 d 14 h decky /trunk/kernel/arch/mips32/src/ add support for halt/reboot in MSIM  
2227 6240 d 4 h decky /trunk/kernel/ start shutdown infrastructure  
2170 6248 d 12 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 6304 d 13 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 6310 d 21 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6321 d 14 h jermar /trunk/ (c) versus (C)  
1993 6377 d 22 h decky /trunk/ make framebuffer code more generic  
1955 6404 d 2 h decky /trunk/kernel/arch/mips32/ timer_fnc -> virtual_timer_fnc  
1944 6411 d 17 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.		  
1936 6413 d 1 h decky /trunk/kernel/arch/mips32/ mips32: update for new IRQ subsystem  
1901 6434 d 19 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 6446 d 17 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1882 6447 d 21 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1881 6448 d 22 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 6488 d 2 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.
