3783 5624 d 6 h rimsky /branches/sparc/kernel/arch/sparc64/ Machine description traversal implemented. Now used to detect CPU frequency.  
3771 5627 d 6 h rimsky /branches/sparc/kernel/arch/sparc64/ Forgotten files comitted to repository.  
3770 5627 d 6 h rimsky /branches/sparc/ Working on Niagara port - TLB initialization, MMU fault status area initialization, hypercall enhancement, modified tick.c so that the (hyperprivileged) TICK register does not have to be accessed. Now the initialization phase proceeds, but some parts of it are omitted for now (e.g. CPU initialization).  
3748 5634 d 7 h rimsky /branches/sparc/kernel/arch/sparc64/ Be careful to preserve the output registers when processing the fast data access MMU miss.  
3745 5634 d 14 h rimsky /branches/sparc/ Merged latest trunk changes (revs 3722 to 3744) into the sparc branch.  
3743 5634 d 15 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 5634 d 15 h rimsky /branches/sparc/ The sparc branch synchronized with trunk at revision 3722 (trunk@3722).  
3665 5658 d 4 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3664 5658 d 5 h rimsky /branches/sparc/ Added some SunBlade 1500 stuff (part of it is just temporary - e.g. the new visual). Some small fixes and enhancements.  
3618 5668 d 5 h rimsky /branches/sparc/ Support for framebuffers, where the first pixel is mapped to a different address than the OBP 'reg' property claims. Cleanup, comments, C-style.  
3607 5669 d 4 h rimsky /branches/sparc/ Cleanup and minor fixes.  
3602 5669 d 8 h rimsky /branches/sparc/ Merge latest trunk changes into the sparc branch.  
3593 5673 d 5 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.  
3591 5673 d 13 h rimsky /branches/sparc/ Making the code compatible also with US-IV (US-IV+) - TLB size based on CPU autodetection, cleanup of code waking up APs. General cleanup.  
3582 5678 d 18 h rimsky /branches/sparc/ Made changes making HelenOS run on US-IV CPUs. Minor refactoring of the SGCN driver.  
3549 5686 d 4 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).  
3514 5695 d 5 h rimsky /branches/sparc/ Input support added to SGCN driver, connected to HelenOS kernel (uspace TBD), so that kconsole is usable.  
3502 5696 d 6 h rimsky /branches/sparc/ Implemented Serengeti console driver (only output, input TBD), all output now goes to the console instead of Simics CLI window.  
3493 5704 d 6 h rimsky /branches/sparc/ More changes making the code US-III-conformant (mainly in mm).  
3492 5707 d 9 h rimsky /branches/sparc/ Changes in trunk merged into the sparc branch. SILO's ramdisk issue solved by the CONFIG_RD_EXTERNAL option.  
3489 5711 d 9 h rimsky /branches/sparc/ More files made conform the US-III specification. (Changes concern mainly TSB.)  
3479 5722 d 13 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 5726 d 8 h rimsky /branches/sparc/kernel/arch/sparc64/ comments  
3467 5729 d 6 h rimsky /branches/sparc/ SMP and CPU initialiation modified to work even with Serengeti OFW tree layout; support for output to the Simics CLI console added (see my blog); some header files modified to conform US-III definition. Now HelenOS (on the sample configuration - usiii.simics) is able to run some userspace tasks.  
3450 5733 d 7 h rimsky /branches/sparc/kernel/arch/sparc64/ Made tlb.h conform US-III specification.  
3440 5734 d 15 h rimsky /branches/sparc/kernel/arch/sparc64/ TLB modifications in order to make functions tlb_print and tlb_invalidate_all work correctly in US-III.  
3398 5739 d 13 h rimsky /branches/sparc/ US used as a code for the UltraSPARC I-II subarchitecture instead of US2.  
3397 5739 d 14 h rimsky /branches/sparc/ Merged recent changes from trunk into the Sparc branch.  
3365 5757 d 5 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 5763 d 11 h decky /branches/sparc/ add sparc branch  
3281 5772 d 10 h jermar /trunk/kernel/arch/ia64/src/ Fix ia64 memcpy() broken in the last change.  
3274 5772 d 12 h jermar /trunk/ memcpy(), memmove() and similar functions return dst instead of src.
Fix all implementations, including those in assembly. ppc32 assembly
version didn't seem to be affected by this.
 
3240 5782 d 17 h decky / move unfinished ObjC support to a separate branch

fix physical memory detection in gxemul (which doesn't honor uncached flag in TLB)
 
3234 5786 d 12 h decky /trunk/ reintroduce support for MSIM text console in user space  
3233 5786 d 12 h decky /trunk/ remove dummy page coloring facility, which is currenty not used
