3743 5651 d 3 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 5651 d 4 h rimsky /branches/sparc/ The sparc branch synchronized with trunk at revision 3722 (trunk@3722).  
3665 5674 d 17 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3664 5674 d 17 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 5684 d 17 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 5685 d 16 h rimsky /branches/sparc/ Cleanup and minor fixes.  
3602 5685 d 20 h rimsky /branches/sparc/ Merge latest trunk changes into the sparc branch.  
3593 5689 d 17 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.  
3591 5690 d 1 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 5695 d 6 h rimsky /branches/sparc/ Made changes making HelenOS run on US-IV CPUs. Minor refactoring of the SGCN driver.  
3549 5702 d 16 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 5711 d 17 h rimsky /branches/sparc/ Input support added to SGCN driver, connected to HelenOS kernel (uspace TBD), so that kconsole is usable.  
3502 5712 d 18 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 5720 d 19 h rimsky /branches/sparc/ More changes making the code US-III-conformant (mainly in mm).  
3492 5723 d 21 h rimsky /branches/sparc/ Changes in trunk merged into the sparc branch. SILO's ramdisk issue solved by the CONFIG_RD_EXTERNAL option.  
3489 5727 d 21 h rimsky /branches/sparc/ More files made conform the US-III specification. (Changes concern mainly TSB.)  
3479 5739 d 2 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 5742 d 20 h rimsky /branches/sparc/kernel/arch/sparc64/ comments  
3467 5745 d 18 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 5749 d 19 h rimsky /branches/sparc/kernel/arch/sparc64/ Made tlb.h conform US-III specification.  
3440 5751 d 3 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 5756 d 2 h rimsky /branches/sparc/ US used as a code for the UltraSPARC I-II subarchitecture instead of US2.  
3397 5756 d 2 h rimsky /branches/sparc/ Merged recent changes from trunk into the Sparc branch.  
3365 5773 d 18 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 5779 d 23 h decky /branches/sparc/ add sparc branch  
3281 5788 d 22 h jermar /trunk/kernel/arch/ia64/src/ Fix ia64 memcpy() broken in the last change.  
3274 5789 d 0 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 5799 d 5 h decky / move unfinished ObjC support to a separate branch  
3236 5802 d 19 h decky /trunk/kernel/arch/mips32/src/mm/ limit physical memory to 512 MB (more cannot be used right now, see ticket #29)
fix physical memory detection in gxemul (which doesn't honor uncached flag in TLB)		  
3234 5803 d 1 h decky /trunk/ reintroduce support for MSIM text console in user space  
3233 5803 d 1 h decky /trunk/ remove dummy page coloring facility, which is currenty not used

cleanup		  
3228 5803 d 12 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		  
3227 5803 d 20 h decky /trunk/kernel/arch/ia32/src/drivers/ remove unnecessary newline

3209 5823 d 19 h jermar /trunk/kernel/arch/ia32/src/smp/ Allocate AP's GDT from first 4 GiB.  
3200 5827 d 3 h svoboda /trunk/kernel/arch/ppc32/src/ Remove buggy assembler memsetb function, call generic C _memsetb instead. Fixes kconsole panic when uspace klog is enabled and memsetb() called from klog_update()
