3467 5850 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 5861 d 1 h rimsky /branches/sparc/ Merged recent changes from trunk into the Sparc branch.  
3365 5878 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 5884 d 21 h decky /branches/sparc/ add sparc branch  
3222 5926 d 22 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3193 5934 d 18 h jermar /trunk/kernel/ cstyle fixes  
3181 5944 d 3 h jermar /trunk/kernel/generic/src/ cstyle for kinit.c and scheduler.c  
3175 5946 d 2 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.
 
3097 5960 d 19 h decky /trunk/kernel/ resurrect klog  
3061 5961 d 23 h decky /trunk/kernel/generic/src/main/ debugging output of kernel initialization  
3060 5961 d 23 h decky /trunk/kernel/generic/src/main/ run init tasks after they are all loaded  
3029 5965 d 23 h decky /trunk/kernel/generic/ fix kernel ramdisk support  
2746 6058 d 21 h decky /trunk/kernel/ start merging tasklets (more or less a rewrite)  
2745 6059 d 2 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2725 6080 d 0 h decky /trunk/kernel/ remove config.memory_size, get_memory_size() and memory_init.{c|d}
the amount of available memory can be calculated from the sizes of the zones
add FRAMES2SIZE, SIZE2KB and SIZE2MB functions/macros (code readability)
 
2701 6092 d 2 h jermar /trunk/kernel/ Fix cstyle and (c) to 2008.  
2447 6329 d 22 h jermar /trunk/kernel/generic/src/main/ Split accidently joined lines.  
2446 6329 d 22 h jermar /trunk/kernel/generic/ More efficient and simpler task termination.

Based on the assumption, that after its creation, only the task itself can create more threads for itself,
the last thread with userspace context to execute thread_exit() will perform futex and IPC cleanup. When
the task has no threads, it is destroyed. Both the cleanup and destruction is controlled by reference
counting.

As for userspace threads, even though there could be a global garbage collector for joining threads, it is
much simpler if the uinit thread detaches itself before switching to userspace.

task_kill() is now an idempotent operation. It just instructs the threads within a task to exit.

Change in the name of a thread state: Undead -> JoinMe.
 
2445 6330 d 0 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2227 6383 d 8 h decky /trunk/kernel/ start shutdown infrastructure
