3862 5754 d 9 h rimsky /branches/sparc/kernel/ Changed the structure of header files, which have sun4u and sun4v versions. Implemented some sun4v TSB functions.  
3743 5794 d 18 h rimsky /branches/sparc/ Started to implement support for sun4v. Bootloader adapted to autodetect the architecture (sun4u, sun4v). Some generic sparc64 kernel files split into sun4u and sun4v versions (but the sun4u is still the default in many cases - in order to keep the code compilable). Implemented taking over the MMU. Implemented routines for performing the hypervisor API calls. Implemented a trivial standard output driver. HelenOS banner can now be printed from the kernel on Niagara.  
3479 5882 d 17 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 5886 d 11 h rimsky /branches/sparc/kernel/arch/sparc64/ comments  
3343 5923 d 14 h decky /branches/sparc/ add sparc branch  
2071 6503 d 10 h jermar /trunk/ (c) versus (C)  
2008 6549 d 11 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
1917 6603 d 11 h jermar /trunk/ sparc64 work:
- hw_map() can now support up to 8M requests
- CPU stacks are now locked in DTLB of the respective processor
- kernel in the boot phase no longer relies on the stack provided by OpenFirmware
- instead of of doing FLUSHW during kernel startup, simply set the
window state registers to the wanted state
- NWINDOW -> NWINDOWS
- Add/fix some comments and copyrights.		  
1899 6616 d 18 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		  
1891 6624 d 9 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1860 6642 d 12 h jermar /trunk/kernel/ A lot of untested sparc64 stuff:
- Write ASID to hardware when a thread is about to run in userspace.
- Add userspace() and switch_to_userspace() functions.
- Handle special cases when the userspace spill/fill handler causes MMU trap.
- Resolve some TODOs in the existing sparc64 code.
- sparc64 has now C99 compliant header guards.
- Formatting and indentation fixes.		  
1854 6644 d 20 h jermar /trunk/kernel/ Define architecture-specific thread sub-constructors and sub-destructors on all architectures.
Define the THREAD_FLAG_USPACE which means that the thread runs in user space.
The forementioned changes allow for allocating of user window buffer on sparc64
threads that execute in userspace.

A lot of formatting and indentation fixes.		  
1852 6647 d 12 h jermar /trunk/kernel/ sparc64 work.
Bunch of changes in preparation for sparc64 mm and userspace support.
Fix alignment of hardcoded_* variables in linker script.		  
1823 6672 d 15 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
Dump take_over_tlb_and_tt() and add its assembly language replacement.		  
1792 6691 d 9 h jermar /trunk/ Move functionality of tlb_arch_init() to take_over_tlb_and_tt().
Call take_over_tlb_and_tt() very early after the kernel starts
executing.		  
1787 6693 d 13 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1702 6721 d 17 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
534 6912 d 11 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6912 d 12 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6924 d 16 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.
