4073 5716 d 21 h rimsky /branches/sparc/ Implemented input and output drivers for Niagara. Written in the old-fashion style (do not use the new DDI infrastructure nor the new keyboard driver). Anyway, tetris can be played.  
3817 5764 d 18 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.  
3770 5784 d 20 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).  
3745 5792 d 3 h rimsky /branches/sparc/ Merged latest trunk changes (revs 3722 to 3744) into the sparc branch.  
3743 5792 d 4 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.  
3665 5815 d 18 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3664 5815 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.  
3607 5826 d 17 h rimsky /branches/sparc/ Cleanup and minor fixes.  
3593 5830 d 18 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.  
3549 5843 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 5852 d 19 h rimsky /branches/sparc/ Input support added to SGCN driver, connected to HelenOS kernel (uspace TBD), so that kconsole is usable.  
3502 5853 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.  
3467 5886 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.  
3343 5921 d 0 h decky /branches/sparc/ add sparc branch  
2510 6269 d 21 h jermar /trunk/kernel/ Experimental support for the cgsix framebuffer, which is found on old Ultra 1
worksations, and the SBUS bus and devices. Not tested.
 
2089 6490 d 4 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6500 d 21 h jermar /trunk/ (c) versus (C)  
1984 6559 d 21 h jermar /trunk/kernel/arch/sparc64/ sparc64 work:
- untested support for Psycho PCI controller
 
1921 6595 d 22 h jermar /trunk/kernel/ Changes in ns16550 and z8530 drivers.
Add some stuff for IRQ notifications to irq_t.
 
1911 6603 d 19 h jermar /trunk/kernel/ Add support for interrupt mapping in the Sabre PCI controller.
Add support for PCI and EBUS interrupt mapping via the OpenFirmware device tree.
Unfortunatelly, the code is not capable enough to earn single ns16550 interrupt.
I suspect something needs to be enabled in the EBUS registers.
