4663 6184 d 15 h rimsky /branches/sparc/kernel/ Implemented detection of execution units, used in a heuristics which prevents the ready threads be unevenly distributed among physical cores by changing the order in which APs are woken up (and hence the order in which the CPUs will be running their kcpulb thread). Cleanup.  
3743 6394 d 16 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.  
3742 6394 d 16 h rimsky /branches/sparc/ The sparc branch synchronized with trunk at revision 3722 (trunk@3722).  
3665 6418 d 6 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3593 6433 d 6 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.  
3549 6446 d 5 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 6464 d 7 h rimsky /branches/sparc/ More changes making the code US-III-conformant (mainly in mm).  
3492 6467 d 10 h rimsky /branches/sparc/ Changes in trunk merged into the sparc branch. SILO's ramdisk issue solved by the CONFIG_RD_EXTERNAL option.  
3398 6499 d 14 h rimsky /branches/sparc/ US used as a code for the UltraSPARC I-II subarchitecture instead of US2.  
3365 6517 d 7 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 6523 d 12 h decky /branches/sparc/ add sparc branch  
3240 6542 d 18 h decky / move unfinished ObjC support to a separate branch  
3228 6547 d 1 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 6600 d 16 h decky /trunk/kernel/ remove ARM machine option
add CONFIG_EDEBUG option		  
2830 6655 d 12 h jermar /trunk/ Add (c) and the modified BSD license to the config system.  
2599 6806 d 5 h decky /trunk/kernel/ replace prescott cpu type with currently more known category  
2585 6817 d 6 h cejka /trunk/ Better fix of labels in configuration script.  
2584 6817 d 7 h cejka /trunk/kernel/ Fixed labels for framebuffer options used by build script.  
2516 6868 d 8 h vana /trunk/kernel/ IA64 rest of neaded changes to work with simics keyboard  
2465 6961 d 14 h jermar /trunk/ Merge arm32 into trunk.  
2443 6969 d 6 h jermar /trunk/ sscc -> suncc  
2442 6969 d 7 h jermar /trunk/ Add dummy option for Sun Studio C Compiler.
For each architecture, offer only compilers that support the target.		  
2437 6969 d 8 h decky /trunk/ experimental support for ICC
(the sources has to be modified to avoid ICC compiler warnings)		  
2227 7021 d 22 h decky /trunk/kernel/ start shutdown infrastructure  
2128 7077 d 9 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 7078 d 9 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2065 7117 d 6 h jermar /trunk/kernel/ Coding style fixes and formatting improvements.  
2064 7117 d 7 h vana /trunk/ SIMICS added as a simulator kernel runs on  
2030 7138 d 17 h decky /trunk/kernel/ thread CPU cycles accounting  
2020 7140 d 10 h decky /trunk/kernel/ integrate more tests  
2019 7140 d 10 h decky /trunk/kernel/ prepare for new test infrastructure  
2018 7140 d 11 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2009 7147 d 7 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
1996 7159 d 10 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 7159 d 10 h jermar /trunk/kernel/ Move general configuration out of debugging configuration.
Add CONFIG_VIRT_IDX_CACHE.		  
1985 7161 d 13 h decky /trunk/kernel/ add benchmarking configuration directive  
1979 7164 d 7 h jermar /trunk/ Configuration changes on sparc64.
Compile TSB support by default.
Ask whether to start AP processors in the loader.		  
1952 7190 d 10 h jermar /trunk/ Rename xen32 to ia32xen.
The name seems to be more logical as Xen supports more host architectures.		  
1903 7215 d 9 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 7220 d 7 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.
