3203 5844 d 9 h svoboda /branches/dynload/ Move stuff related to running programs to a separate source file proc/program.c  
3197 5849 d 6 h svoboda /branches/dynload/ Merge latest changes from trunk to dynload  
3191 5850 d 8 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
3153 5864 d 8 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
3149 5864 d 8 h svoboda /branches/dynload/ Merge trunk changes up to r3071 into dynload (broken)  
3107 5874 d 13 h svoboda /branches/dynload/ Merge trunk changes up to r3044 into dynload  
3001 5886 d 7 h svoboda /branches/dynload/kernel/generic/ Kernel support for running programs from userspace.  
2927 5896 d 11 h decky /branches/dynload/ added dynload branch  
2746 5974 d 5 h decky /trunk/kernel/ start merging tasklets (more or less a rewrite)  
2745 5974 d 9 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2725 5995 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 6007 d 9 h jermar /trunk/kernel/ Fix cstyle and (c) to 2008.  
2447 6245 d 5 h jermar /trunk/kernel/generic/src/main/ Split accidently joined lines.  
2446 6245 d 6 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 6245 d 7 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2227 6298 d 15 h decky /trunk/kernel/ start shutdown infrastructure  
2223 6298 d 22 h decky /trunk/kernel/generic/src/ add mcall0 command (calling a function on each CPU)  
2118 6361 d 6 h decky /trunk/kernel/generic/src/ explicit typecast, fix signed/unsigned comparison  
2089 6369 d 8 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2087 6370 d 4 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2071 6380 d 1 h jermar /trunk/ (c) versus (C)  
2070 6380 d 8 h jermar /trunk/ Rather big indentation and formatting changes.
More inteligent long line wrapping.
 
2066 6392 d 6 h jermar /trunk/kernel/generic/src/main/ Formatting changes.
Bump year in kernel copyright.
 
2048 6412 d 2 h jermar /trunk/ Formatting and indentation changes.  
2042 6414 d 5 h decky /trunk/kernel/ introduce uncounted threads, whose accounting doesn't affect accumulated task accounting
run tests in kconsole thread again
 
2039 6414 d 9 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
2019 6417 d 3 h decky /trunk/kernel/ prepare for new test infrastructure  
2015 6419 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 6428 d 6 h decky /trunk/ update rd  
2002 6428 d 8 h decky /trunk/kernel/generic/ rd work  
2000 6430 d 10 h decky /trunk/kernel/ move files to more proper locations  
1999 6430 d 10 h decky /trunk/ start RAM disk support  
1901 6493 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 6499 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 6521 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 6521 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 6548 d 21 h decky /trunk/kernel/ more sophisticated initial stack handling  
1826 6549 d 3 h decky /trunk/kernel/generic/src/main/ some debugging output  
1787 6570 d 3 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6577 d 4 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).
