2268 6296 d 10 h jermar /trunk/kernel/generic/ Document and assert proper usage of THREAD_FLAG_WIRED.
Original patch by Jan Hudecek.
 
2227 6305 d 23 h decky /trunk/kernel/ start shutdown infrastructure  
2218 6307 d 5 h decky /trunk/kernel/ support the possibility to send EOI or Interrupt Acknowledgement
prior to processing the interrupt
(this is essential on some architectures to prevent preemption deadlock)
 
2216 6307 d 9 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2208 6307 d 11 h decky /trunk/kernel/generic/ use spinlock only on console output, not other print functions
cleanup
 
2187 6308 d 16 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2183 6309 d 13 h jermar /trunk/kernel/generic/ Continue to de-oversynchronize the kernel.
- replace as->refcount with an atomic counter; accesses to this
reference counter are not to be done when the as->lock mutex is held;
this gets us rid of mutex_lock_active();

Remove the possibility of a deadlock between TLB shootdown and asidlock.
- get rid of mutex_lock_active() on as->lock
- when locking the asidlock spinlock, always do it conditionally and with
preemption disabled; in the unsuccessful case, enable interrupts and try again
- there should be no deadlock between TLB shootdown and the as->lock mutexes
- PLEASE REVIEW !!!

Add DEADLOCK_PROBE's to places where we have spinlock_trylock() loops.
 
2170 6314 d 6 h jermar /trunk/kernel/ Simplify synchronization in as_switch().
The function was oversynchronized, which
was causing deadlocks on the address
space mutex.

Now, address spaces can only be switched
when the asidlock is held. This also protects
stealing of ASIDs. No other synchronization
is necessary.
 
2142 6317 d 14 h jermar /trunk/kernel/generic/include/mm/ Remove out of date comment.  
2128 6361 d 10 h jermar /trunk/ Add arm32 architecture. The 32 suffix is used to specify that 16-bit Thumb
instructions are not used. The arm32 code is mostly composed of placeholders
that need to be replaced by real implementation. So far, the arm32 tree
only compiles. If run under GXEmul simulator, an infinit loop at the
kernel entry point will be entered.
 
2126 6362 d 6 h decky /trunk/kernel/ small cleanup, more work coming  
2125 6362 d 9 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2124 6362 d 10 h decky /trunk/kernel/generic/ implement simple realloc()  
2122 6368 d 13 h decky /trunk/kernel/generic/ explicit typecast, fix signed/unsigned comparison  
2120 6368 d 14 h decky /trunk/kernel/generic/include/syscall/ specify syscall handler arguments  
2109 6369 d 17 h jermar /trunk/kernel/generic/ Revert thread_interrupt_sleep() to waitq_interrupt_sleep().
I'd prefer that this, IMO, waitq related stuff stays together.
 
2107 6370 d 7 h jermar /trunk/ When clock() is called by an external interrupt dispatched by the IRQ dispatcher,
no spinlock can be held or the kernel will not be preemptive. This fixes Ticket #24.

Formating and indentation fixes.
 
2106 6370 d 15 h jermar /trunk/kernel/ Merge as_t structure into one and leave the differring parts in as_genarch_t.

Indentation and formatting changes in header files.
 
2105 6374 d 16 h decky /trunk/kernel/ move ipc structures to ipc.h  
2103 6375 d 9 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h
 
2098 6375 d 11 h decky /trunk/kernel/generic/ avoid conflict with potential keyword  
2096 6375 d 11 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2094 6375 d 11 h decky /trunk/kernel/generic/ avoid conflict with potential keyword  
2093 6375 d 11 h decky /trunk/kernel/ spinlock extern declaration macro  
2092 6375 d 12 h decky /trunk/kernel/generic/include/ move cpu_t to cpu.h  
2090 6376 d 12 h decky /trunk/kernel/generic/include/proc/ cleanup garbage  
2089 6376 d 15 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2085 6382 d 14 h decky /trunk/kernel/ typedef elimination  
2083 6382 d 15 h decky /trunk/kernel/ typedef elimination  
2081 6382 d 16 h decky /trunk/kernel/generic/include/ another typedefs to anonymous structs  
2080 6382 d 16 h decky /trunk/kernel/generic/include/ another typedef to anonymous enum  
2079 6383 d 10 h decky /trunk/kernel/ remove some typedefs in favor of anonymous structures  
2071 6387 d 8 h jermar /trunk/ (c) versus (C)  
2059 6410 d 17 h jermar /trunk/kernel/generic/ Improve indentation and formatting.  
2050 6416 d 19 h decky /trunk/kernel/ benchmarking with statistics (initial)  
2048 6419 d 10 h jermar /trunk/ Formatting and indentation changes.  
2042 6421 d 12 h decky /trunk/kernel/ introduce uncounted threads, whose accounting doesn't affect accumulated task accounting
run tests in kconsole thread again
 
2039 6421 d 16 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
2031 6422 d 17 h decky /trunk/kernel/generic/include/proc/ fix comment  
2030 6422 d 17 h decky /trunk/kernel/ thread CPU cycles accounting
