3770 5602 d 16 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 5609 d 23 h rimsky /branches/sparc/ Merged latest trunk changes (revs 3722 to 3744) into the sparc branch.  
3742 5610 d 1 h rimsky /branches/sparc/ The sparc branch synchronized with trunk at revision 3722 (trunk@3722).  
3665 5633 d 14 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3607 5644 d 13 h rimsky /branches/sparc/ Cleanup and minor fixes.  
3602 5644 d 17 h rimsky /branches/sparc/ Merge latest trunk changes into the sparc branch.  
3593 5648 d 14 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.  
3582 5654 d 4 h rimsky /branches/sparc/ Made changes making HelenOS run on US-IV CPUs. Minor refactoring of the SGCN driver.  
3549 5661 d 14 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 5670 d 15 h rimsky /branches/sparc/ Input support added to SGCN driver, connected to HelenOS kernel (uspace TBD), so that kconsole is usable.  
3492 5682 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 5704 d 16 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 5715 d 0 h rimsky /branches/sparc/ Merged recent changes from trunk into the Sparc branch.  
3365 5732 d 15 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 5738 d 20 h decky /branches/sparc/ add sparc branch  
3332 5742 d 0 h jermar /trunk/kernel/generic/src/ipc/ Fix types when processing IPC_M_DATA_WRITE arguments.  
3274 5747 d 22 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 5751 d 19 h jermar /trunk/ cstyle  
3240 5758 d 3 h decky / move unfinished ObjC support to a separate branch  
3233 5761 d 22 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
3229 5762 d 2 h jermar /trunk/kernel/generic/include/ Improve definition of generic macros.  
3228 5762 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 5764 d 3 h jermar /trunk/kernel/generic/src/sysinfo/ Check the validity of the 'len' argument for sysinfo syscalls.  
3222 5780 d 21 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3208 5782 d 17 h jermar /trunk/kernel/generic/ The real intention of the previous commit was to put the boundary
on 4 GiB, not 16 GiB.
 
3207 5782 d 18 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 5782 d 19 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 5782 d 21 h jermar /trunk/kernel/generic/src/mm/ Fix deadlock in the 'zones' kconsole command.  
3198 5787 d 18 h svoboda /trunk/ Use initrd with mips32 port. Increase memory size.  
3194 5788 d 2 h jermar /trunk/kernel/generic/src/console/ Remove left-over debugging stuff.  
3193 5788 d 17 h jermar /trunk/kernel/ cstyle fixes  
3188 5795 d 14 h jermar /trunk/kernel/generic/src/mm/ Finer grained waiting for memory with consideration of the number
of available memory frames.
 
3187 5795 d 19 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.
 
3186 5795 d 19 h jermar /trunk/kernel/ Support for active mutexes. Active mutexes implement busy waiting, pretty much
in the same way as spinlocks, but can be passed to condition variables, which is
the motivation for this enhancement.
 
3185 5796 d 18 h jermar /trunk/kernel/generic/src/mm/ cstyle for frame.c  
3184 5796 d 21 h jermar /trunk/kernel/generic/src/ipc/ Fix a scary two-year old bug: do not attempt to initialize a call structure if
its allocation failed.
 
3183 5796 d 23 h jermar /trunk/kernel/generic/src/mm/ Avoid easy deadlock while printing slab cache statistics.  
3182 5796 d 23 h jermar /trunk/kernel/generic/include/mm/ cstyle for slab.h  
3181 5798 d 2 h jermar /trunk/kernel/generic/src/ cstyle for kinit.c and scheduler.c  
3180 5798 d 4 h jermar /trunk/kernel/generic/src/mm/ cstyle for slab.c
