2696 5975 d 7 h decky /trunk/kernel/arch/mips32/ initial support for dorder device in MSIM  
2634 6019 d 16 h decky /trunk/kernel/arch/mips32/src/ fix trivial bug in storing lastcount  
2633 6019 d 16 h decky /trunk/kernel/arch/mips32/ CPU cycle accounting on MIPS  
2607 6035 d 0 h jermar /trunk/ Support for six syscall arguments on mips32.  
2232 6255 d 20 h decky /trunk/kernel/arch/mips32/src/ add support for halt/reboot in MSIM  
2227 6256 d 10 h decky /trunk/kernel/ start shutdown infrastructure  
2170 6264 d 18 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 6320 d 19 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 6327 d 3 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6337 d 20 h jermar /trunk/ (c) versus (C)  
1993 6394 d 4 h decky /trunk/ make framebuffer code more generic  
1955 6420 d 8 h decky /trunk/kernel/arch/mips32/ timer_fnc -> virtual_timer_fnc  
1944 6427 d 23 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.		  
1936 6429 d 7 h decky /trunk/kernel/arch/mips32/ mips32: update for new IRQ subsystem  
1901 6451 d 2 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 6463 d 0 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1882 6464 d 3 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1881 6465 d 4 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 6504 d 8 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.		  
1812 6515 d 2 h decky /trunk/kernel/ move macro and cleanup
