3770 5632 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 5640 d 3 h rimsky /branches/sparc/ Merged latest trunk changes (revs 3722 to 3744) into the sparc branch.  
3742 5640 d 5 h rimsky /branches/sparc/ The sparc branch synchronized with trunk at revision 3722 (trunk@3722).  
3665 5663 d 18 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3607 5674 d 17 h rimsky /branches/sparc/ Cleanup and minor fixes.  
3602 5674 d 21 h rimsky /branches/sparc/ Merge latest trunk changes into the sparc branch.  
3593 5678 d 18 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.  
3582 5684 d 8 h rimsky /branches/sparc/ Made changes making HelenOS run on US-IV CPUs. Minor refactoring of the SGCN driver.  
3549 5691 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 5700 d 19 h rimsky /branches/sparc/ Input support added to SGCN driver, connected to HelenOS kernel (uspace TBD), so that kconsole is usable.  
3492 5712 d 22 h rimsky /branches/sparc/ Changes in trunk merged into the sparc branch. SILO's ramdisk issue solved by the CONFIG_RD_EXTERNAL option.  
3467 5734 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.  
3397 5745 d 4 h rimsky /branches/sparc/ Merged recent changes from trunk into the Sparc branch.  
3365 5762 d 19 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 5769 d 0 h decky /branches/sparc/ add sparc branch  
3332 5772 d 4 h jermar /trunk/kernel/generic/src/ipc/ Fix types when processing IPC_M_DATA_WRITE arguments.  
3274 5778 d 2 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 5781 d 23 h jermar /trunk/ cstyle  
3240 5788 d 7 h decky / move unfinished ObjC support to a separate branch  
3225 5794 d 7 h jermar /trunk/kernel/generic/src/sysinfo/ Check the validity of the 'len' argument for sysinfo syscalls.  
3222 5811 d 1 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3208 5812 d 21 h jermar /trunk/kernel/generic/ The real intention of the previous commit was to put the boundary
on 4 GiB, not 16 GiB.
 
3207 5812 d 22 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 5812 d 23 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 5813 d 1 h jermar /trunk/kernel/generic/src/mm/ Fix deadlock in the 'zones' kconsole command.  
3194 5818 d 6 h jermar /trunk/kernel/generic/src/console/ Remove left-over debugging stuff.  
3193 5818 d 21 h jermar /trunk/kernel/ cstyle fixes  
3188 5825 d 18 h jermar /trunk/kernel/generic/src/mm/ Finer grained waiting for memory with consideration of the number
of available memory frames.
 
3187 5825 d 22 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 5825 d 23 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 5826 d 22 h jermar /trunk/kernel/generic/src/mm/ cstyle for frame.c  
3184 5827 d 1 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 5827 d 3 h jermar /trunk/kernel/generic/src/mm/ Avoid easy deadlock while printing slab cache statistics.  
3181 5828 d 6 h jermar /trunk/kernel/generic/src/ cstyle for kinit.c and scheduler.c  
3180 5828 d 8 h jermar /trunk/kernel/generic/src/mm/ cstyle for slab.c  
3175 5830 d 5 h jermar /trunk/kernel/generic/src/main/ Don't print anything before the kernel initializes the first THE
structure. This fixes a regression introduced in r3061. If anything
worked from r3061 until now, it was only due to luck. arm32 was not
that lucky when built with gcc 4.3.1.
 
3143 5835 d 1 h svoboda /trunk/kernel/ Implement smc_coherence[_block]() for ppc32  
3142 5835 d 1 h svoboda /trunk/kernel/generic/src/mm/ Fix build when smc_coherence_block() is defined as an empty macro  
3141 5835 d 4 h jermar /trunk/kernel/generic/src/mm/ Maintain cache coherence when the ELF backend duplicates a frame from an
executable segment.
 
3137 5835 d 6 h jermar /trunk/kernel/generic/src/proc/ Maintain cache coherence after sys_task_spawn() copies ELF image from user space.
