4679 5404 d 12 h rimsky /branches/sparc/kernel/ Enhancing the way how even distribution of threads over processor cores is achieved.  
4638 5424 d 13 h rimsky /branches/sparc/kernel/ SMP on Niagara made working: debugged the problem with the 'non-deterministic' symptoms, implemented the IPI mechanism.  
4073 5547 d 8 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.  
3993 5557 d 6 h rimsky /branches/sparc/kernel/ Implemented preemptible trap handler for userspace (including syscalls - did not forget enabling interrupts for them) and the ralated stuff. Implemented handlers of instruction/data MMU miss/protection. Now some userspace tasks are run; there are, however, still some bugs causing unexpected data MMU misses.  
3862 5582 d 6 h rimsky /branches/sparc/kernel/ Changed the structure of header files, which have sun4u and sun4v versions. Implemented some sun4v TSB functions.  
3817 5595 d 6 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 5600 d 6 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).  
3770 5615 d 7 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 5622 d 15 h rimsky /branches/sparc/ Merged latest trunk changes (revs 3722 to 3744) into the sparc branch.  
3742 5622 d 16 h rimsky /branches/sparc/ The sparc branch synchronized with trunk at revision 3722 (trunk@3722).  
3665 5646 d 5 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3607 5657 d 5 h rimsky /branches/sparc/ Cleanup and minor fixes.  
3602 5657 d 9 h rimsky /branches/sparc/ Merge latest trunk changes into the sparc branch.  
3593 5661 d 6 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.  
3582 5666 d 19 h rimsky /branches/sparc/ Made changes making HelenOS run on US-IV CPUs. Minor refactoring of the SGCN driver.  
3549 5674 d 5 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 5683 d 6 h rimsky /branches/sparc/ Input support added to SGCN driver, connected to HelenOS kernel (uspace TBD), so that kconsole is usable.  
3492 5695 d 10 h rimsky /branches/sparc/ Changes in trunk merged into the sparc branch. SILO's ramdisk issue solved by the CONFIG_RD_EXTERNAL option.  
3467 5717 d 7 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.  
3397 5727 d 15 h rimsky /branches/sparc/ Merged recent changes from trunk into the Sparc branch.  
3365 5745 d 6 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 5751 d 12 h decky /branches/sparc/ add sparc branch  
3332 5754 d 15 h jermar /trunk/kernel/generic/src/ipc/ Fix types when processing IPC_M_DATA_WRITE arguments.  
3274 5760 d 13 h jermar /trunk/ memcpy(), memmove() and similar functions return dst instead of src.
Fix all implementations, including those in assembly. ppc32 assembly
version didn't seem to be affected by this.
 
3246 5764 d 10 h jermar /trunk/ cstyle  
3240 5770 d 18 h decky / move unfinished ObjC support to a separate branch  
3233 5774 d 13 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
3229 5774 d 17 h jermar /trunk/kernel/generic/include/ Improve definition of generic macros.  
3228 5775 d 1 h decky /trunk/ physical memory detection in MSIM (discontinous regions supported)
remove Sgi Indy (ARC) support -- it was unmaintaned, untested for years and without uspace support
 
3225 5776 d 18 h jermar /trunk/kernel/generic/src/sysinfo/ Check the validity of the 'len' argument for sysinfo syscalls.  
3222 5793 d 12 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3208 5795 d 8 h jermar /trunk/kernel/generic/ The real intention of the previous commit was to put the boundary
on 4 GiB, not 16 GiB.
 
3207 5795 d 9 h jermar /trunk/kernel/generic/ Introduce FRAME_LOW_16_GiB slab/frame allocator flag. When specified, the
allocators will not allocate memory above 16 GiB. Each architecture needs to
make sure not to merge zones from below and above 16 GiB. Allocations that
require memory below 16 GiB need to be altered to use this flag.
 
3206 5795 d 10 h jermar /trunk/kernel/generic/ Avoid deadlock during the 'zone n' kconsole command. Buddy allocator detail is
no longer printed because the effort to avoid the deadlock was simply not worth
it.
 
3205 5795 d 12 h jermar /trunk/kernel/generic/src/mm/ Fix deadlock in the 'zones' kconsole command.  
3198 5800 d 9 h svoboda /trunk/ Use initrd with mips32 port. Increase memory size.  
3194 5800 d 17 h jermar /trunk/kernel/generic/src/console/ Remove left-over debugging stuff.  
3193 5801 d 8 h jermar /trunk/kernel/ cstyle fixes  
3188 5808 d 6 h jermar /trunk/kernel/generic/src/mm/ Finer grained waiting for memory with consideration of the number
of available memory frames.
 
3187 5808 d 10 h jermar /trunk/kernel/generic/src/mm/ Get rid of the infamous "Sleep not implemented" panic during low memory
condition. Use a condition variable to implement the sleep. As of now, the
condition is rather coarse and can cause that threads may sleep unnecessarily.
Needs to be fine tuned and based on the amount of memory available.
