2746 5972 d 4 h decky /trunk/kernel/ start merging tasklets (more or less a rewrite)  
2745 5972 d 9 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2725 5993 d 7 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 6005 d 9 h jermar /trunk/kernel/ Fix cstyle and (c) to 2008.  
2447 6243 d 5 h jermar /trunk/kernel/generic/src/main/ Split accidently joined lines.  
2446 6243 d 5 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 6243 d 7 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2227 6296 d 15 h decky /trunk/kernel/ start shutdown infrastructure  
2223 6296 d 22 h decky /trunk/kernel/generic/src/ add mcall0 command (calling a function on each CPU)  
2118 6359 d 6 h decky /trunk/kernel/generic/src/ explicit typecast, fix signed/unsigned comparison  
2089 6367 d 8 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2087 6368 d 4 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2071 6378 d 1 h jermar /trunk/ (c) versus (C)  
2070 6378 d 8 h jermar /trunk/ Rather big indentation and formatting changes.
More inteligent long line wrapping.
 
2066 6390 d 6 h jermar /trunk/kernel/generic/src/main/ Formatting changes.
Bump year in kernel copyright.
 
2048 6410 d 2 h jermar /trunk/ Formatting and indentation changes.  
2042 6412 d 4 h decky /trunk/kernel/ introduce uncounted threads, whose accounting doesn't affect accumulated task accounting
run tests in kconsole thread again
 
2039 6412 d 9 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
2019 6415 d 3 h decky /trunk/kernel/ prepare for new test infrastructure  
2015 6417 d 1 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 6426 d 6 h decky /trunk/ update rd  
2002 6426 d 8 h decky /trunk/kernel/generic/ rd work  
2000 6428 d 10 h decky /trunk/kernel/ move files to more proper locations  
1999 6428 d 10 h decky /trunk/ start RAM disk support  
1901 6491 d 6 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.
 
1894 6497 d 23 h jermar /trunk/ Add balloc() (a.k.a boot allocator):
- balloc() only needs to know how to allocate memory.
- Memory allocated via balloc() is supposed to be passed to kernel and never freed by boot itself.
- make kernel aware of boot allocations

More work on OFW device tree:
- use balloc() to efficiently and safely allocate memory for the canonical copy of the device tree

sparc64 boot:
- pass OFW device tree root node pointer to kernel
 
1855 6519 d 6 h jermar /trunk/kernel/ sparc64 work.

Fix bug introduced in revision 1852. When fixing CWP,
the input registers of the current window (i.e. output
registers of the window belonging to the interrupted
context) must be preserved. Preserve those registers
in memory. Sure there exist more efficient ways how to
copy the inputs.

Simplify before_thread_runs_arch(), resp. after_thread_ran_arch(),
and make them install, resp. uninstall, DTLB locked mapping for
eventual userspace window buffer.
 
1854 6519 d 10 h jermar /trunk/kernel/ Define architecture-specific thread sub-constructors and sub-destructors on all architectures.
Define the THREAD_FLAG_USPACE which means that the thread runs in user space.
The forementioned changes allow for allocating of user window buffer on sparc64
threads that execute in userspace.

A lot of formatting and indentation fixes.
 
1833 6546 d 21 h decky /trunk/kernel/ more sophisticated initial stack handling  
1826 6547 d 3 h decky /trunk/kernel/generic/src/main/ some debugging output  
1787 6568 d 3 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6575 d 4 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6589 d 9 h jermar /kernel/trunk/ Cleanup of comments.  
1729 6591 d 21 h decky /kernel/trunk/generic/src/main/ coding style changes  
1705 6595 d 10 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.
 
1702 6596 d 7 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1662 6601 d 12 h palkovsky /kernel/trunk/generic/src/main/ Responsive kconsole after test finished.  
1659 6601 d 13 h vana /kernel/trunk/generic/src/main/ No uspace if tests  
1595 6603 d 14 h palkovsky /kernel/trunk/ Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.
TODO: Fix vsnprintf return value(and behaviour according to specs) and remove workaround in klog.
 
1581 6604 d 13 h jermar /kernel/trunk/generic/src/ Detach kmp thread after joining it.
Extend assertion in thread_destroy() to not panic when threads are destroyed in their Unded state.
