3549 5721 d 20 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 5739 d 22 h rimsky /branches/sparc/ More changes making the code US-III-conformant (mainly in mm).  
3492 5743 d 1 h rimsky /branches/sparc/ Changes in trunk merged into the sparc branch. SILO's ramdisk issue solved by the CONFIG_RD_EXTERNAL option.  
3398 5775 d 6 h rimsky /branches/sparc/ US used as a code for the UltraSPARC I-II subarchitecture instead of US2.  
3365 5792 d 22 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 5799 d 3 h decky /branches/sparc/ add sparc branch  
3240 5818 d 9 h decky / move unfinished ObjC support to a separate branch  
3228 5822 d 16 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 5876 d 7 h decky /trunk/kernel/ remove ARM machine option
add CONFIG_EDEBUG option		  
2830 5931 d 3 h jermar /trunk/ Add (c) and the modified BSD license to the config system.  
2599 6081 d 20 h decky /trunk/kernel/ replace prescott cpu type with currently more known category  
2585 6092 d 21 h cejka /trunk/ Better fix of labels in configuration script.  
2584 6092 d 22 h cejka /trunk/kernel/ Fixed labels for framebuffer options used by build script.  
2516 6143 d 23 h vana /trunk/kernel/ IA64 rest of neaded changes to work with simics keyboard  
2465 6237 d 5 h jermar /trunk/ Merge arm32 into trunk.  
2443 6244 d 21 h jermar /trunk/ sscc -> suncc  
2442 6244 d 22 h jermar /trunk/ Add dummy option for Sun Studio C Compiler.
For each architecture, offer only compilers that support the target.		  
2437 6244 d 23 h decky /trunk/ experimental support for ICC
(the sources has to be modified to avoid ICC compiler warnings)		  
2227 6297 d 13 h decky /trunk/kernel/ start shutdown infrastructure  
2128 6353 d 0 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 6354 d 0 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2065 6392 d 22 h jermar /trunk/kernel/ Coding style fixes and formatting improvements.  
2064 6392 d 22 h vana /trunk/ SIMICS added as a simulator kernel runs on  
2030 6414 d 8 h decky /trunk/kernel/ thread CPU cycles accounting  
2020 6416 d 1 h decky /trunk/kernel/ integrate more tests  
2019 6416 d 1 h decky /trunk/kernel/ prepare for new test infrastructure  
2018 6416 d 2 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2009 6422 d 22 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
1996 6435 d 1 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 6435 d 1 h jermar /trunk/kernel/ Move general configuration out of debugging configuration.
Add CONFIG_VIRT_IDX_CACHE.		  
1985 6437 d 4 h decky /trunk/kernel/ add benchmarking configuration directive  
1979 6439 d 22 h jermar /trunk/ Configuration changes on sparc64.
Compile TSB support by default.
Ask whether to start AP processors in the loader.		  
1952 6466 d 1 h jermar /trunk/ Rename xen32 to ia32xen.
The name seems to be more logical as Xen supports more host architectures.		  
1903 6491 d 0 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 6495 d 22 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 6501 d 0 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 6505 d 6 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1844 6540 d 1 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).		  
1818 6554 d 23 h decky /trunk/kernel/ make burst updates  
1816 6556 d 4 h decky /trunk/kernel/ xen memory initialization
