4663 5633 d 4 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 5843 d 5 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 5843 d 6 h rimsky /branches/sparc/ The sparc branch synchronized with trunk at revision 3722 (trunk@3722).  
3665 5866 d 19 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3593 5881 d 19 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.  
3549 5894 d 19 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 5912 d 21 h rimsky /branches/sparc/ More changes making the code US-III-conformant (mainly in mm).  
3492 5915 d 23 h rimsky /branches/sparc/ Changes in trunk merged into the sparc branch. SILO's ramdisk issue solved by the CONFIG_RD_EXTERNAL option.  
3398 5948 d 4 h rimsky /branches/sparc/ US used as a code for the UltraSPARC I-II subarchitecture instead of US2.  
3365 5965 d 20 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 5972 d 1 h decky /branches/sparc/ add sparc branch  
3240 5991 d 7 h decky / move unfinished ObjC support to a separate branch  
3228 5995 d 14 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 6049 d 5 h decky /trunk/kernel/ remove ARM machine option
add CONFIG_EDEBUG option		  
2830 6104 d 1 h jermar /trunk/ Add (c) and the modified BSD license to the config system.  
2599 6254 d 19 h decky /trunk/kernel/ replace prescott cpu type with currently more known category  
2585 6265 d 20 h cejka /trunk/ Better fix of labels in configuration script.  
2584 6265 d 20 h cejka /trunk/kernel/ Fixed labels for framebuffer options used by build script.  
2516 6316 d 21 h vana /trunk/kernel/ IA64 rest of neaded changes to work with simics keyboard  
2465 6410 d 3 h jermar /trunk/ Merge arm32 into trunk.  
2443 6417 d 19 h jermar /trunk/ sscc -> suncc  
2442 6417 d 20 h jermar /trunk/ Add dummy option for Sun Studio C Compiler.
For each architecture, offer only compilers that support the target.		  
2437 6417 d 21 h decky /trunk/ experimental support for ICC
(the sources has to be modified to avoid ICC compiler warnings)		  
2227 6470 d 12 h decky /trunk/kernel/ start shutdown infrastructure  
2128 6525 d 23 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 6526 d 22 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2065 6565 d 20 h jermar /trunk/kernel/ Coding style fixes and formatting improvements.  
2064 6565 d 20 h vana /trunk/ SIMICS added as a simulator kernel runs on  
2030 6587 d 6 h decky /trunk/kernel/ thread CPU cycles accounting  
2020 6588 d 23 h decky /trunk/kernel/ integrate more tests  
2019 6588 d 23 h decky /trunk/kernel/ prepare for new test infrastructure  
2018 6589 d 0 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2009 6595 d 21 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
1996 6607 d 23 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 6608 d 0 h jermar /trunk/kernel/ Move general configuration out of debugging configuration.
Add CONFIG_VIRT_IDX_CACHE.		  
1985 6610 d 3 h decky /trunk/kernel/ add benchmarking configuration directive  
1979 6612 d 20 h jermar /trunk/ Configuration changes on sparc64.
Compile TSB support by default.
Ask whether to start AP processors in the loader.		  
1952 6638 d 23 h jermar /trunk/ Rename xen32 to ia32xen.
The name seems to be more logical as Xen supports more host architectures.		  
1903 6663 d 22 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 6668 d 20 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.
