4614 5450 d 18 h rimsky /branches/sparc/kernel/arch/sparc64/ Waking CPUs up on sun4v. Weird errors occur when accessing the THE structure.  
4130 5563 d 17 h rimsky /branches/sparc/ Cleanup of the Niagara port. The main purpose of these changes is to make it easy to find out which code is generic, which is sun4u-specific and which is sun4v-specific.  
3993 5576 d 14 h rimsky /branches/sparc/kernel/ Implemented preemptible trap handler for userspace (including syscalls - did not forget enabling interrupts for them) and the ralated stuff. Implemented handlers of instruction/data MMU miss/protection. Now some userspace tasks are run; there are, however, still some bugs causing unexpected data MMU misses.  
3664 5665 d 14 h rimsky /branches/sparc/ Added some SunBlade 1500 stuff (part of it is just temporary - e.g. the new visual). Some small fixes and enhancements.  
3593 5680 d 14 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.  
3479 5729 d 23 h rimsky /branches/sparc/ Names containing 'UPA' replaced with strings containing more general 'ICBUS'. SMART_FIRMWARE option replaced with CPU autodetection + new option CONFIG_A_OUT_ISOFS_B.  
3477 5733 d 17 h rimsky /branches/sparc/kernel/arch/sparc64/ comments  
3343 5770 d 20 h decky /branches/sparc/ add sparc branch  
3071 5847 d 22 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style		  
2089 6340 d 0 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2082 6346 d 0 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6350 d 17 h jermar /trunk/ (c) versus (C)  
2068 6358 d 0 h jermar /trunk/kernel/ Formatting and indentation fixes.  
1911 6453 d 15 h jermar /trunk/kernel/ Add support for interrupt mapping in the Sabre PCI controller.
Add support for PCI and EBUS interrupt mapping via the OpenFirmware device tree.
Unfortunatelly, the code is not capable enough to earn single ns16550 interrupt.
I suspect something needs to be enabled in the EBUS registers.		  
1899 6464 d 0 h jermar /trunk/ sparc64 work:
- Loader now starts all processors.
- Kernel halts all but the bootstrup processor for now.
- Read clock-frequency from the respective processor node in the device tree		  
1885 6476 d 4 h jermar /trunk/kernel/arch/sparc64/include/ On sparc64, get_stack_base() must use the unbiased %sp (i.e. %sp + 2047).  
1882 6477 d 0 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1881 6478 d 0 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.		  
1880 6479 d 16 h jermar /trunk/ Small improvements here and there.  
1865 6485 d 18 h jermar /trunk/kernel/ sparc64 kernel fixes
