4344 5538 d 4 h svoboda /branches/dynload/ Merge trunk changes up to r3988 to dynload.  
4343 5538 d 4 h svoboda /branches/dynload/ Merged trunk changes up to r3925 to dynload.  
3403 5765 d 15 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
3211 5834 d 15 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
3191 5841 d 12 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
3150 5855 d 12 h svoboda /branches/dynload/ Merge trunk changes up to r3090 into dynload (still broken)  
3001 5877 d 11 h svoboda /branches/dynload/kernel/generic/ Kernel support for running programs from userspace.  
2984 5880 d 12 h svoboda /branches/dynload/ Add as_area_change_flags() syscall and libc wrapper. Implementation limited to non-shared areas of anonymous memory.  
2927 5887 d 16 h decky /branches/dynload/ added dynload branch  
2745 5965 d 14 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2725 5986 d 11 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)		  
2556 6116 d 15 h jermar /trunk/kernel/generic/ Rename as_get_size() to as_area_get_size() and add a doxygen comment.  
2465 6229 d 11 h jermar /trunk/ Merge arm32 into trunk.  
2444 6237 d 2 h jermar /trunk/kernel/ First fixes for suncc support.
It is going to be a long way...		  
2183 6293 d 9 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 6298 d 3 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 6301 d 10 h jermar /trunk/kernel/generic/include/mm/ Remove out of date comment.  
2126 6346 d 3 h decky /trunk/kernel/ small cleanup, more work coming
