4130 5820 d 7 h rimsky /branches/sparc/ Cleanup of the Niagara port. The main purpose of these changes is to make it easy to find out which code is generic, which is sun4u-specific and which is sun4v-specific.  
4073 5823 d 7 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.  
3862 5858 d 5 h rimsky /branches/sparc/kernel/ Changed the structure of header files, which have sun4u and sun4v versions. Implemented some sun4v TSB functions.  
3817 5871 d 4 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 5891 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).  
3745 5898 d 13 h rimsky /branches/sparc/ Merged latest trunk changes (revs 3722 to 3744) into the sparc branch.  
3742 5898 d 15 h rimsky /branches/sparc/ The sparc branch synchronized with trunk at revision 3722 (trunk@3722).  
3665 5922 d 4 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3618 5932 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.  
3549 5950 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 5959 d 5 h rimsky /branches/sparc/ Input support added to SGCN driver, connected to HelenOS kernel (uspace TBD), so that kconsole is usable.  
3343 6027 d 11 h decky /branches/sparc/ add sparc branch  
2089 6596 d 14 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6607 d 7 h jermar /trunk/ (c) versus (C)  
1931 6699 d 8 h jermar /trunk/ Add support for IPC notifications even for polled ns16550 based keyboard.  
1897 6723 d 14 h jermar /trunk/ Convert sparc64 framebuffer code to configure from the OpenFirmware device tree memory representation.  
1896 6724 d 6 h jermar /trunk/ Convert sparc64 to detect keyboard and determine
its physical address by walking the memory representation
of the OpenFirmware device tree.

Add bus-specific functions that know how to apply the
"ranges" property to one component of the "reg" property.
Buses supported so far include FHC, EBUS and PCI.
 
1888 6732 d 10 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1880 6736 d 6 h jermar /trunk/ Small improvements here and there.  
1875 6739 d 7 h jermar /trunk/ sparc64 work.
- Changes to enable userspace keyboard drivers.
- Fix z8530 initialization (i.e. clear any pending Tx interrupts).
- Experimental support for framebuffers with inverted colors.
