3593 5702 d 3 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.  
3582 5707 d 17 h rimsky /branches/sparc/ Made changes making HelenOS run on US-IV CPUs. Minor refactoring of the SGCN driver.  
3549 5715 d 3 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 5724 d 4 h rimsky /branches/sparc/ Input support added to SGCN driver, connected to HelenOS kernel (uspace TBD), so that kconsole is usable.  
3492 5736 d 7 h rimsky /branches/sparc/ Changes in trunk merged into the sparc branch. SILO's ramdisk issue solved by the CONFIG_RD_EXTERNAL option.  
3467 5758 d 5 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 5768 d 13 h rimsky /branches/sparc/ Merged recent changes from trunk into the Sparc branch.  
3365 5786 d 4 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 5792 d 9 h decky /branches/sparc/ add sparc branch  
3222 5834 d 10 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3193 5842 d 6 h jermar /trunk/kernel/ cstyle fixes  
3181 5851 d 15 h jermar /trunk/kernel/generic/src/ cstyle for kinit.c and scheduler.c  
3175 5853 d 14 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 5868 d 7 h decky /trunk/kernel/ resurrect klog  
3061 5869 d 11 h decky /trunk/kernel/generic/src/main/ debugging output of kernel initialization  
3060 5869 d 11 h decky /trunk/kernel/generic/src/main/ run init tasks after they are all loaded  
3029 5873 d 11 h decky /trunk/kernel/generic/ fix kernel ramdisk support  
2746 5966 d 10 h decky /trunk/kernel/ start merging tasklets (more or less a rewrite)  
2745 5966 d 14 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2725 5987 d 12 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 5999 d 14 h jermar /trunk/kernel/ Fix cstyle and (c) to 2008.  
2447 6237 d 10 h jermar /trunk/kernel/generic/src/main/ Split accidently joined lines.  
2446 6237 d 11 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 6237 d 12 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2227 6290 d 20 h decky /trunk/kernel/ start shutdown infrastructure  
2223 6291 d 3 h decky /trunk/kernel/generic/src/ add mcall0 command (calling a function on each CPU)  
2118 6353 d 11 h decky /trunk/kernel/generic/src/ explicit typecast, fix signed/unsigned comparison  
2089 6361 d 13 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2087 6362 d 9 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2071 6372 d 6 h jermar /trunk/ (c) versus (C)  
2070 6372 d 13 h jermar /trunk/ Rather big indentation and formatting changes.
More inteligent long line wrapping.
 
2066 6384 d 11 h jermar /trunk/kernel/generic/src/main/ Formatting changes.
Bump year in kernel copyright.
 
2048 6404 d 7 h jermar /trunk/ Formatting and indentation changes.  
2042 6406 d 10 h decky /trunk/kernel/ introduce uncounted threads, whose accounting doesn't affect accumulated task accounting
run tests in kconsole thread again
 
2039 6406 d 14 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
2019 6409 d 8 h decky /trunk/kernel/ prepare for new test infrastructure  
2015 6411 d 6 h jermar /trunk/ Rework support for virtually indexed cache.
Instead of repeatedly flushing the data cache, which was a huge overkill, refuse to create an illegal address alias
in the kernel (again) and allocate appropriate page color in userspace instead. Extend the detection also to
SYS_PHYSMEM_MAP syscall.

Add support for tracking physical memory areas mappable by SYS_PHYSMEM_MAP.

Lots of coding style changes.
 
2005 6420 d 11 h decky /trunk/ update rd  
2002 6420 d 13 h decky /trunk/kernel/generic/ rd work  
2000 6422 d 15 h decky /trunk/kernel/ move files to more proper locations
