2446 6186 d 14 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 6186 d 16 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2227 6240 d 0 h decky /trunk/kernel/ start shutdown infrastructure  
2223 6240 d 6 h decky /trunk/kernel/generic/src/ add mcall0 command (calling a function on each CPU)  
2118 6302 d 15 h decky /trunk/kernel/generic/src/ explicit typecast, fix signed/unsigned comparison  
2089 6310 d 16 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2087 6311 d 12 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2071 6321 d 9 h jermar /trunk/ (c) versus (C)  
2070 6321 d 17 h jermar /trunk/ Rather big indentation and formatting changes.
More inteligent long line wrapping.
 
2066 6333 d 14 h jermar /trunk/kernel/generic/src/main/ Formatting changes.
Bump year in kernel copyright.
 
2048 6353 d 11 h jermar /trunk/ Formatting and indentation changes.  
2042 6355 d 13 h decky /trunk/kernel/ introduce uncounted threads, whose accounting doesn't affect accumulated task accounting
run tests in kconsole thread again
 
2039 6355 d 17 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
2019 6358 d 11 h decky /trunk/kernel/ prepare for new test infrastructure  
2015 6360 d 9 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 6369 d 14 h decky /trunk/ update rd  
2002 6369 d 16 h decky /trunk/kernel/generic/ rd work  
2000 6371 d 19 h decky /trunk/kernel/ move files to more proper locations  
1999 6371 d 19 h decky /trunk/ start RAM disk support  
1901 6434 d 15 h jermar /trunk/kernel/ Make SMP related parts of main.c more generic.
Move initialization of local APIC to architecture specific code.
Add arch_post_cpu_init() to support the above.
