2201 6292 d 0 h jancik /branches/arm/kernel/generic/ Alf: Temporary kernel hack ... redirecting kernel printf function to aux_printf to kernel prints was visible  
2200 6292 d 0 h jancik /branches/arm/kernel/arch/arm32/src/ Alf: nothing important arm32 ... comment unnesesary things, dummy.S each symbol have different address so you can found what function call fall down  
2199 6292 d 0 h jancik /branches/arm/kernel/arch/arm32/ Alf: Memory management update  
2198 6292 d 0 h jancik /branches/arm/ Alf: Start kernel at 0x8010 0000 with paging enabled  
2197 6292 d 5 h kebrt /branches/arm/kernel/arch/arm32/ linker script reverted & -fno-zero-initialized-in-bss added

2195 6292 d 6 h kebrt /branches/arm/kernel/arch/arm32/include/ comments & formatting  
2194 6292 d 6 h kebrt /branches/arm/kernel/arch/arm32/ linker script cleaned (not sure about all changes, but problem with stack_safe != 0 solved)  
2193 6292 d 7 h decky /trunk/uspace/tester/ reimplement all tests from original ipcc
(cleanup needed)		  
2192 6292 d 7 h decky /trunk/uspace/libc/arch/sparc64/include/ fix uspace atomic_add according kernel code  
2191 6292 d 7 h kebrt /branches/arm/kernel/arch/arm32/include/ stack constants  
2190 6292 d 7 h kebrt /branches/arm/kernel/arch/arm32/include/ get_stack_base() added  
2189 6292 d 7 h kebrt /branches/arm/kernel/arch/arm32/ ARM CPU identification  
2188 6292 d 7 h decky /trunk/ new user space testing framework (unfinished)  
2187 6292 d 8 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2186 6292 d 9 h decky /trunk/uspace/tester/ rename ipcc.c to tester.c  
2185 6292 d 9 h decky /trunk/ rename ipcc to tester  
2184 6292 d 11 h decky /trunk/kernel/generic/src/lib/ add zetta (sextillion) prefix
make constants explicitly unsigned		  
2183 6293 d 5 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.		  
2182 6293 d 22 h jancik /branches/arm/kernel/arch/arm32/ Alf: Paging ... not tested
