2275 6285 d 13 h decky /trunk/kernel/generic/ add fancy uptime kconsole command  
2268 6287 d 13 h jermar /trunk/kernel/generic/ Document and assert proper usage of THREAD_FLAG_WIRED.
Original patch by Jan Hudecek.
 
2227 6297 d 2 h decky /trunk/kernel/ start shutdown infrastructure  
2218 6298 d 8 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 6298 d 12 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2208 6298 d 14 h decky /trunk/kernel/generic/ use spinlock only on console output, not other print functions
cleanup
 
2187 6299 d 19 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2183 6300 d 16 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 6305 d 9 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2142 6308 d 17 h jermar /trunk/kernel/generic/include/mm/ Remove out of date comment.  
2128 6352 d 13 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 6353 d 9 h decky /trunk/kernel/ small cleanup, more work coming  
2125 6353 d 12 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2124 6353 d 14 h decky /trunk/kernel/generic/ implement simple realloc()  
2122 6359 d 16 h decky /trunk/kernel/generic/ explicit typecast, fix signed/unsigned comparison  
2120 6359 d 17 h decky /trunk/kernel/generic/include/syscall/ specify syscall handler arguments  
2109 6360 d 20 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 6361 d 10 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 6361 d 18 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 6365 d 19 h decky /trunk/kernel/ move ipc structures to ipc.h  
2103 6366 d 12 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h
 
2098 6366 d 14 h decky /trunk/kernel/generic/ avoid conflict with potential keyword  
2096 6366 d 14 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2094 6366 d 14 h decky /trunk/kernel/generic/ avoid conflict with potential keyword  
2093 6366 d 15 h decky /trunk/kernel/ spinlock extern declaration macro  
2092 6366 d 16 h decky /trunk/kernel/generic/include/ move cpu_t to cpu.h  
2090 6367 d 15 h decky /trunk/kernel/generic/include/proc/ cleanup garbage  
2089 6367 d 18 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2085 6373 d 17 h decky /trunk/kernel/ typedef elimination  
2083 6373 d 18 h decky /trunk/kernel/ typedef elimination  
2081 6373 d 19 h decky /trunk/kernel/generic/include/ another typedefs to anonymous structs  
2080 6373 d 19 h decky /trunk/kernel/generic/include/ another typedef to anonymous enum  
2079 6374 d 13 h decky /trunk/kernel/ remove some typedefs in favor of anonymous structures  
2071 6378 d 11 h jermar /trunk/ (c) versus (C)  
2059 6401 d 20 h jermar /trunk/kernel/generic/ Improve indentation and formatting.  
2050 6407 d 22 h decky /trunk/kernel/ benchmarking with statistics (initial)  
2048 6410 d 13 h jermar /trunk/ Formatting and indentation changes.  
2042 6412 d 15 h decky /trunk/kernel/ introduce uncounted threads, whose accounting doesn't affect accumulated task accounting
run tests in kconsole thread again
 
2039 6412 d 19 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
2031 6413 d 20 h decky /trunk/kernel/generic/include/proc/ fix comment
