4614 5422 d 4 h rimsky /branches/sparc/kernel/arch/sparc64/ Waking CPUs up on sun4v. Weird errors occur when accessing the THE structure.  
4130 5535 d 4 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 5548 d 1 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 5637 d 1 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 5652 d 0 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.  
3479 5701 d 9 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 5705 d 4 h rimsky /branches/sparc/kernel/arch/sparc64/ comments  
3343 5742 d 7 h decky /branches/sparc/ add sparc branch  
3071 5819 d 8 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style		  
2089 6311 d 10 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2082 6317 d 10 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6322 d 3 h jermar /trunk/ (c) versus (C)  
2068 6329 d 10 h jermar /trunk/kernel/ Formatting and indentation fixes.  
1911 6425 d 1 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 6435 d 10 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 6447 d 15 h jermar /trunk/kernel/arch/sparc64/include/ On sparc64, get_stack_base() must use the unbiased %sp (i.e. %sp + 2047).  
1882 6448 d 10 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1881 6449 d 10 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 6451 d 2 h jermar /trunk/ Small improvements here and there.  
1865 6457 d 4 h jermar /trunk/kernel/ sparc64 kernel fixes
