3748 5613 d 21 h rimsky /branches/sparc/kernel/arch/sparc64/ Be careful to preserve the output registers when processing the fast data access MMU miss.  
3745 5614 d 3 h rimsky /branches/sparc/ Merged latest trunk changes (revs 3722 to 3744) into the sparc branch.  
3743 5614 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 5614 d 5 h rimsky /branches/sparc/ The sparc branch synchronized with trunk at revision 3722 (trunk@3722).  
3665 5637 d 18 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3664 5637 d 19 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 5647 d 19 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 5648 d 18 h rimsky /branches/sparc/ Cleanup and minor fixes.  
3593 5652 d 18 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.  
3591 5653 d 3 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 5658 d 8 h rimsky /branches/sparc/ Made changes making HelenOS run on US-IV CPUs. Minor refactoring of the SGCN driver.  
3549 5665 d 18 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 5674 d 19 h rimsky /branches/sparc/ Input support added to SGCN driver, connected to HelenOS kernel (uspace TBD), so that kconsole is usable.  
3502 5675 d 20 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 5683 d 20 h rimsky /branches/sparc/ More changes making the code US-III-conformant (mainly in mm).  
3492 5686 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.  
3489 5690 d 23 h rimsky /branches/sparc/ More files made conform the US-III specification. (Changes concern mainly TSB.)  
3479 5702 d 3 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 5705 d 22 h rimsky /branches/sparc/kernel/arch/sparc64/ comments  
3467 5708 d 20 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.
