3817 5599 d 5 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.  
3801 5603 d 7 h rimsky /branches/sparc/kernel/arch/sparc64/src/trap/sun4v/ Minor fixes in the preemptible trap handler.  
3798 5604 d 5 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 5616 d 6 h rimsky /branches/sparc/kernel/arch/sparc64/ Machine description traversal implemented. Now used to detect CPU frequency.  
3771 5619 d 6 h rimsky /branches/sparc/kernel/arch/sparc64/ Forgotten files comitted to repository.  
3770 5619 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 5626 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 5626 d 13 h rimsky /branches/sparc/ Merged latest trunk changes (revs 3722 to 3744) into the sparc branch.  
3743 5626 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 5626 d 15 h rimsky /branches/sparc/ The sparc branch synchronized with trunk at revision 3722 (trunk@3722).  
3665 5650 d 4 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3664 5650 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 5660 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 5661 d 4 h rimsky /branches/sparc/ Cleanup and minor fixes.  
3602 5661 d 8 h rimsky /branches/sparc/ Merge latest trunk changes into the sparc branch.  
3593 5665 d 4 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.  
3592 5665 d 5 h rimsky /branches/sparc/ Simics configuration script booting HelenOS on Niagara added.  
3591 5665 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 5670 d 18 h rimsky /branches/sparc/ Made changes making HelenOS run on US-IV CPUs. Minor refactoring of the SGCN driver.  
3549 5678 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 5687 d 5 h rimsky /branches/sparc/ Input support added to SGCN driver, connected to HelenOS kernel (uspace TBD), so that kconsole is usable.  
3502 5688 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 5696 d 6 h rimsky /branches/sparc/ More changes making the code US-III-conformant (mainly in mm).  
3492 5699 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 5703 d 9 h rimsky /branches/sparc/ More files made conform the US-III specification. (Changes concern mainly TSB.)  
3479 5714 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 5718 d 8 h rimsky /branches/sparc/kernel/arch/sparc64/ comments  
3467 5721 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 5725 d 7 h rimsky /branches/sparc/kernel/arch/sparc64/ Made tlb.h conform US-III specification.  
3440 5726 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 5731 d 13 h rimsky /branches/sparc/ US used as a code for the UltraSPARC I-II subarchitecture instead of US2.  
3397 5731 d 14 h rimsky /branches/sparc/ Merged recent changes from trunk into the Sparc branch.  
3365 5749 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 5755 d 11 h decky /branches/sparc/ add sparc branch  
3335 5756 d 6 h jermar /trunk/uspace/srv/fs/fat/ Support for readdir() on FAT.  
3334 5758 d 13 h jermar /trunk/uspace/lib/libc/generic/ Let ipc_data_{read|write}_start() use the async framework.  
3332 5758 d 14 h jermar /trunk/kernel/generic/src/ipc/ Fix types when processing IPC_M_DATA_WRITE arguments.  
3331 5758 d 15 h jermar /trunk/uspace/lib/libc/generic/vfs/ Fix canonify() to set correct length even for paths that have no components.  
3328 5758 d 17 h jermar /trunk/uspace/lib/libc/generic/vfs/ Fix off-by-one bug in absolutize().  
3325 5759 d 7 h jermar /trunk/uspace/srv/fs/fat/ Determine the size of a directory node by walking the FAT and counting clusters.
This eliminates the hardcoded limit on the number of directory entries.
