4679 5446 d 22 h rimsky /branches/sparc/kernel/ Enhancing the way how even distribution of threads over processor cores is achieved.  
4638 5466 d 23 h rimsky /branches/sparc/kernel/ SMP on Niagara made working: debugged the problem with the 'non-deterministic' symptoms, implemented the IPI mechanism.  
4073 5589 d 18 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 5599 d 15 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 5624 d 16 h rimsky /branches/sparc/kernel/ Changed the structure of header files, which have sun4u and sun4v versions. Implemented some sun4v TSB functions.  
3817 5637 d 15 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 5642 d 16 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 5657 d 17 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 5665 d 0 h rimsky /branches/sparc/ Merged latest trunk changes (revs 3722 to 3744) into the sparc branch.  
3742 5665 d 2 h rimsky /branches/sparc/ The sparc branch synchronized with trunk at revision 3722 (trunk@3722).  
3665 5688 d 15 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3607 5699 d 14 h rimsky /branches/sparc/ Cleanup and minor fixes.  
3602 5699 d 18 h rimsky /branches/sparc/ Merge latest trunk changes into the sparc branch.  
3593 5703 d 15 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.  
3582 5709 d 5 h rimsky /branches/sparc/ Made changes making HelenOS run on US-IV CPUs. Minor refactoring of the SGCN driver.  
3549 5716 d 15 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 5725 d 16 h rimsky /branches/sparc/ Input support added to SGCN driver, connected to HelenOS kernel (uspace TBD), so that kconsole is usable.  
3492 5737 d 19 h rimsky /branches/sparc/ Changes in trunk merged into the sparc branch. SILO's ramdisk issue solved by the CONFIG_RD_EXTERNAL option.  
3467 5759 d 17 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 5770 d 1 h rimsky /branches/sparc/ Merged recent changes from trunk into the Sparc branch.  
3365 5787 d 16 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 5793 d 21 h decky /branches/sparc/ add sparc branch  
3332 5797 d 1 h jermar /trunk/kernel/generic/src/ipc/ Fix types when processing IPC_M_DATA_WRITE arguments.  
3274 5802 d 23 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 5806 d 20 h jermar /trunk/ cstyle  
3240 5813 d 4 h decky / move unfinished ObjC support to a separate branch  
3233 5816 d 23 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
3229 5817 d 3 h jermar /trunk/kernel/generic/include/ Improve definition of generic macros.  
3228 5817 d 10 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 5819 d 4 h jermar /trunk/kernel/generic/src/sysinfo/ Check the validity of the 'len' argument for sysinfo syscalls.  
3222 5835 d 22 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3208 5837 d 18 h jermar /trunk/kernel/generic/ The real intention of the previous commit was to put the boundary
on 4 GiB, not 16 GiB.
 
3207 5837 d 19 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 5837 d 20 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 5837 d 22 h jermar /trunk/kernel/generic/src/mm/ Fix deadlock in the 'zones' kconsole command.  
3198 5842 d 19 h svoboda /trunk/ Use initrd with mips32 port. Increase memory size.  
3194 5843 d 3 h jermar /trunk/kernel/generic/src/console/ Remove left-over debugging stuff.  
3193 5843 d 18 h jermar /trunk/kernel/ cstyle fixes  
3188 5850 d 15 h jermar /trunk/kernel/generic/src/mm/ Finer grained waiting for memory with consideration of the number
of available memory frames.
 
3187 5850 d 20 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.
