3817 5655 d 1 h rimsky /branches/sparc/kernel/ Progress on Niagara: Commented out portions of mm, which are not required for kernel threads (temporarily). Scheduler is working. Implemented a driver of hypervisor's standard input. Kernel console is usable.  
3798 5660 d 1 h rimsky /branches/sparc/kernel/ Implemented preemptible trap handler for sun4v for trapping from kernel (not userspace). Not properly tested/debugged yet. HelenOS now reaches the as_install_arch function (where it, of course, fails).  
3783 5672 d 2 h rimsky /branches/sparc/kernel/arch/sparc64/ Machine description traversal implemented. Now used to detect CPU frequency.  
3771 5675 d 2 h rimsky /branches/sparc/kernel/arch/sparc64/ Forgotten files comitted to repository.  
3770 5675 d 2 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 5682 d 3 h rimsky /branches/sparc/kernel/arch/sparc64/ Be careful to preserve the output registers when processing the fast data access MMU miss.  
3745 5682 d 10 h rimsky /branches/sparc/ Merged latest trunk changes (revs 3722 to 3744) into the sparc branch.  
3743 5682 d 11 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 5682 d 12 h rimsky /branches/sparc/ The sparc branch synchronized with trunk at revision 3722 (trunk@3722).  
3665 5706 d 1 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3664 5706 d 1 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 5716 d 1 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 5717 d 0 h rimsky /branches/sparc/ Cleanup and minor fixes.  
3593 5721 d 1 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.  
3591 5721 d 9 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 5726 d 14 h rimsky /branches/sparc/ Made changes making HelenOS run on US-IV CPUs. Minor refactoring of the SGCN driver.  
3549 5734 d 0 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 5743 d 1 h rimsky /branches/sparc/ Input support added to SGCN driver, connected to HelenOS kernel (uspace TBD), so that kconsole is usable.  
3502 5744 d 2 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 5752 d 3 h rimsky /branches/sparc/ More changes making the code US-III-conformant (mainly in mm).  
3492 5755 d 5 h rimsky /branches/sparc/ Changes in trunk merged into the sparc branch. SILO's ramdisk issue solved by the CONFIG_RD_EXTERNAL option.  
3489 5759 d 5 h rimsky /branches/sparc/ More files made conform the US-III specification. (Changes concern mainly TSB.)  
3479 5770 d 10 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 5774 d 4 h rimsky /branches/sparc/kernel/arch/sparc64/ comments  
3467 5777 d 2 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 5781 d 3 h rimsky /branches/sparc/kernel/arch/sparc64/ Made tlb.h conform US-III specification.  
3440 5782 d 11 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.  
3397 5787 d 10 h rimsky /branches/sparc/ Merged recent changes from trunk into the Sparc branch.  
3343 5811 d 7 h decky /branches/sparc/ add sparc branch  
3233 5834 d 9 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
3145 5876 d 16 h jermar /trunk/kernel/arch/sparc64/include/ On sparc64, when the operand to the FLUSH instruction doesn't matter, the
instruction's semantics is to flush the pipeline.
 
3134 5877 d 13 h jermar /trunk/kernel/arch/ Add smc_coherence_block().  
3133 5878 d 3 h jermar /trunk/kernel/arch/ Add smc_coherence() macro to all architectures.
So far, only amd64, ia32, ia64 and sparc64 are implemented.
 
3104 5885 d 16 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.
