3665 5718 d 14 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3593 5733 d 15 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.  
3549 5746 d 14 h rimsky /branches/sparc/ Implemented uspace Serengeti drivers for kbd and fb. Integrated with other parts of HelenOS. Now it is possible to play Tetris on a simulated Serengeti machine (usiii.simics).  
3493 5764 d 16 h rimsky /branches/sparc/ More changes making the code US-III-conformant (mainly in mm).  
3492 5767 d 19 h rimsky /branches/sparc/ Changes in trunk merged into the sparc branch. SILO's ramdisk issue solved by the CONFIG_RD_EXTERNAL option.  
3398 5799 d 23 h rimsky /branches/sparc/ US used as a code for the UltraSPARC I-II subarchitecture instead of US2.  
3365 5817 d 15 h rimsky /branches/sparc/ Integrated US-III port into the build process; added script for downloading and patching SILO; added patched SILO binaries; modified sources of the Sparc64 port up to the beginning of the main_bsp_separated_stack function: phys. address size not hardwired but configurable (41 bits on US-II, 43 bits on US-III), WSTATE register implicitly written 0 on startup.  
3343 5823 d 21 h decky /branches/sparc/ add sparc branch  
3240 5843 d 3 h decky / move unfinished ObjC support to a separate branch  
3228 5847 d 10 h decky /trunk/ physical memory detection in MSIM (discontinous regions supported)
remove Sgi Indy (ARC) support -- it was unmaintaned, untested for years and without uspace support		  
3051 5901 d 1 h decky /trunk/kernel/ remove ARM machine option
add CONFIG_EDEBUG option		  
2830 5955 d 21 h jermar /trunk/ Add (c) and the modified BSD license to the config system.  
2599 6106 d 14 h decky /trunk/kernel/ replace prescott cpu type with currently more known category  
2585 6117 d 15 h cejka /trunk/ Better fix of labels in configuration script.  
2584 6117 d 16 h cejka /trunk/kernel/ Fixed labels for framebuffer options used by build script.  
2516 6168 d 16 h vana /trunk/kernel/ IA64 rest of neaded changes to work with simics keyboard  
2465 6261 d 22 h jermar /trunk/ Merge arm32 into trunk.  
2443 6269 d 15 h jermar /trunk/ sscc -> suncc  
2442 6269 d 15 h jermar /trunk/ Add dummy option for Sun Studio C Compiler.
For each architecture, offer only compilers that support the target.		  
2437 6269 d 16 h decky /trunk/ experimental support for ICC
(the sources has to be modified to avoid ICC compiler warnings)		  
2227 6322 d 7 h decky /trunk/kernel/ start shutdown infrastructure  
2128 6377 d 18 h jermar /trunk/ Add arm32 architecture. The 32 suffix is used to specify that 16-bit Thumb
instructions are not used. The arm32 code is mostly composed of placeholders
that need to be replaced by real implementation. So far, the arm32 tree
only compiles. If run under GXEmul simulator, an infinit loop at the
kernel entry point will be entered.		  
2125 6378 d 17 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2065 6417 d 15 h jermar /trunk/kernel/ Coding style fixes and formatting improvements.  
2064 6417 d 16 h vana /trunk/ SIMICS added as a simulator kernel runs on  
2030 6439 d 1 h decky /trunk/kernel/ thread CPU cycles accounting  
2020 6440 d 19 h decky /trunk/kernel/ integrate more tests  
2019 6440 d 19 h decky /trunk/kernel/ prepare for new test infrastructure  
2018 6440 d 20 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2009 6447 d 16 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
1996 6459 d 19 h jermar /trunk/kernel/ Add option to compile the sparc64 kernel without the TTE_CV bit support.
The bit is not used by default now.
Enabling it may theoretically lead to physical memory inconsistencies until code that
mitigates the problem is written.		  
1995 6459 d 19 h jermar /trunk/kernel/ Move general configuration out of debugging configuration.
Add CONFIG_VIRT_IDX_CACHE.		  
1985 6461 d 22 h decky /trunk/kernel/ add benchmarking configuration directive  
1979 6464 d 16 h jermar /trunk/ Configuration changes on sparc64.
Compile TSB support by default.
Ask whether to start AP processors in the loader.		  
1952 6490 d 19 h jermar /trunk/ Rename xen32 to ia32xen.
The name seems to be more logical as Xen supports more host architectures.		  
1903 6515 d 17 h jermar /trunk/ SMP stuff for sparc64.
Almost complete except for IPIs.
The absence of IPI support deadlocks
the kernel when more CPUs are configured.		  
1896 6520 d 16 h jermar /trunk/ Convert sparc64 to detect keyboard and determine
its physical address by walking the memory representation
of the OpenFirmware device tree.

Add bus-specific functions that know how to apply the
"ranges" property to one component of the "reg" property.
Buses supported so far include FHC, EBUS and PCI.		  
1889 6525 d 17 h jermar /trunk/kernel/ Fix bug in mm/as.c:
- as_area_destroy() should not work with AS but as

sparc64 work:
- start implementing TSB support		  
1882 6530 d 0 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1844 6564 d 19 h jermar /trunk/kernel/ Add an option to compile the sparc64 kernel for Ultra 5 or Enterprise E6500.
Basic keyboard support (polling) based on ns16550 serial port (deployed on Ultra).
