Rev	Age	Author	Path	Log message
2222	6284 d 1 h	decky	/trunk/kernel/	map kernel pages explicitly as writable (this solves compatibility issues with Intel Core 2) make VESA framebuffer initialization more robust
2221	6284 d 3 h	decky	/trunk/kernel/arch/ia32/src/boot/	fix typo in comment
2220	6284 d 3 h	decky	/trunk/kernel/arch/ia32/src/boot/	check for PSE support, add error message on PSE not present make initial mapping explicitly writeable, turn PAE explicitly off (just in case)
2219	6284 d 4 h	decky	/trunk/kernel/arch/amd64/src/boot/	add error message on no long mode support
2218	6284 d 22 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)
2217	6284 d 23 h	jermar	/trunk/kernel/arch/ia32/src/smp/	On SMP amd64 and ia32 systems, release the irq->lock before calling clock() from the interrupt handler. This is important for maintaining kernel preemption since no preemption can take place while a spinlock is held.
2216	6285 d 2 h	decky	/trunk/	make thread ID 64 bit (task ID is 64 bit already) cleanup thread syscalls
2211	6285 d 4 h	decky	/trunk/kernel/generic/src/synch/	reflect the renaming of printflock to printf_lock
2210	6285 d 4 h	decky	/trunk/	use more useful values
2209	6285 d 4 h	decky	/trunk/uspace/	use futex instead of pthread serialization synchronize only output to stdout cleanup
2208	6285 d 4 h	decky	/trunk/kernel/generic/	use spinlock only on console output, not other print functions cleanup
2193	6286 d 7 h	decky	/trunk/uspace/tester/	reimplement all tests from original ipcc (cleanup needed)
2192	6286 d 7 h	decky	/trunk/uspace/libc/arch/sparc64/include/	fix uspace atomic_add according kernel code
2188	6286 d 8 h	decky	/trunk/	new user space testing framework (unfinished)
2187	6286 d 9 h	decky	/trunk/kernel/generic/	add syscall for getting current thread ID
2186	6286 d 10 h	decky	/trunk/uspace/tester/	rename ipcc.c to tester.c
2185	6286 d 10 h	decky	/trunk/	rename ipcc to tester
2184	6286 d 12 h	decky	/trunk/kernel/generic/src/lib/	add zetta (sextillion) prefix make constants explicitly unsigned
2183	6287 d 6 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	6292 d 0 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.
