3661	5694 d 5 h	vana	/trunk/	IA64: repair similators support
3659	5694 d 14 h	vana	/trunk/kernel/arch/ia64/src/	Fix changed param order to ns16550_init function call
3657	5694 d 14 h	vana	/trunk/	Legacy IRQ support, uspace NS16550 support, some minor changes
3655	5695 d 6 h	jermar	/trunk/kernel/	Add additional members to the irq_t structure so that an interrupt-driven driver does not need to know how to clear the level interrupt. The z8530 was modified in this way and is much more generic. The ns16550 driver has also been modified, but awaits testing. The sparc64 interrupt mapping and dispatch code is now using the new info and calls the clear-interrupt-routine itself.
3654	5695 d 8 h	jermar	/trunk/kernel/arch/sparc64/	After my effort yesterday, there are two rival psycho drivers. Merge the two and remove the newer one.
3649	5696 d 4 h	jermar	/trunk/kernel/arch/sparc64/src/drivers/	More work on the psycho driver.
3647	5696 d 5 h	jermar	/trunk/kernel/arch/sparc64/	Improvized Psycho driver.
3646	5696 d 7 h	jermar	/trunk/kernel/	Initial support for interrupt driven driver for ns16550.
3635	5699 d 6 h	vana	/trunk/	IA64: Userspace I/O support
3631	5700 d 5 h	jermar	/trunk/kernel/arch/ia32/src/	The IA-32 manual is very secretive about the fact that the SYSENTER instruction disables interrupts (I found only one evidence of this in the instruction's pseudo code). The sysenter_handler needs to reenable the interrupts in order to preserve the preemptive nature of the kernel.
3626	5701 d 10 h	vana	/trunk/kernel/	Classic TLB shootdown support on ia64
3619	5701 d 18 h	vana	/trunk/kernel/arch/ia64/src/smp/	IA64:smp.c Remove not important logs
3616	5702 d 10 h	vana	/trunk/	IA64 correctly find CPU wakeup vector from SAL & EFI memory map support
3594	5706 d 6 h	svoboda	/trunk/kernel/arch/ppc32/src/mm/	Handle page faults from userspace properly on ppc32, do not panic.
3587	5711 d 14 h	jermar	/trunk/kernel/arch/ppc64/src/mm/	Remove one more occurrence of "Page fault.\n".
3586	5711 d 14 h	jermar	/trunk/kernel/arch/	Do not print "Page fault.\n" if a mapping is not found during TLB refill.
3585	5711 d 16 h	svoboda	/trunk/	Fix bug #67. It was obviously all my fault - I allocated r3 for pcb_ptr, which was alredy used by uarg.
3584	5711 d 16 h	svoboda	/trunk/kernel/arch/ppc32/src/mm/	Bugfix: A ppc32 task would hang if it touched unmapped memory - was calling printf() with address-space mutex held.
3583	5711 d 19 h	vana	/trunk/	IA64: Support for real frequency
3580	5713 d 4 h	jermar	/trunk/kernel/arch/sparc64/include/	Accesses to memory mapped registers should use volatile pointers so that the compiler doesn't even think of trying to be clever. Add memory barriers and fixed cstyle.
3578	5713 d 18 h	vana	/trunk/	Alfa of SMP support on IA64
3577	5713 d 19 h	vana	/trunk/kernel/	Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver
3490	5744 d 9 h	vana	/trunk/kernel/arch/ia64/include/	Macro naming correction
3485	5750 d 5 h	jermar	/trunk/	Support for SYSENTER on ia32.
3482	5753 d 6 h	jermar	/trunk/kernel/arch/sparc64/	Do not allocate full page for the uspace window buffer. Instead, allocate only the bare minimum to fit NWINDOWS - 1 uspace windows and to satisfy alignment requirements.
3463	5765 d 11 h	jermar	/trunk/kernel/arch/sparc64/	Populate all sparc64 trap table slots belonging to trap_instruction_n.
3458	5766 d 6 h	jermar	/trunk/kernel/arch/sparc64/src/trap/	Add sparc64 trap table entries so that the maximum syscall number is 0x40.
3416	5771 d 10 h	svoboda	/trunk/kernel/arch/arm32/include/	Merge changeset 3122 from tracing to trunk. (Add missing include)
3406	5771 d 15 h	svoboda	/trunk/kernel/arch/ppc32/include/	Merge changeset 3114 from tracing into trunk. (implementation of istate_from_uspace() for ppc32)
3393	5777 d 5 h	jermar	/trunk/kernel/arch/mips32/src/mm/	Write protection fault should not panic the mips32 kernel if it happens during copy_to_uspace().
3392	5777 d 6 h	jermar	/trunk/kernel/arch/mips32/src/mm/	cstyle for mips32's tlb.c
3391	5777 d 20 h	jermar	/trunk/	Remove ia64 legacy init address and init size macros. Remove now unneeded vmaxlma.c.
3390	5777 d 20 h	jermar	/trunk/kernel/arch/mips32/	Get rid of mips32 legacy init address and size macros.
3381	5785 d 6 h	jermar	/trunk/kernel/arch/ia32/include/	Prevent 'tmp' in ia32's atomic_lock_arch() from being allocated to the same register as 'val->count'.
3380	5785 d 7 h	jermar	/trunk/kernel/arch/amd64/include/	Prevent 'tmp' in amd64's atomic_lock_arch() from being allocated to the same register as 'val->count'.
3379	5785 d 17 h	jermar	/trunk/kernel/arch/sparc64/include/	Add the missing preemption_disable() call to sparc64 atomic_lock_arch(). Thanks to Pavel Rimsky for noticing this.
3369	5789 d 9 h	decky	/trunk/	configurable cross-compiler prefix (using CROSS_PREFIX)
3368	5789 d 10 h	decky	/trunk/	configurable cross-compiler prefix (using CROSS_PREFIX)
3281	5806 d 9 h	jermar	/trunk/kernel/arch/ia64/src/	Fix ia64 memcpy() broken in the last change.
3274	5806 d 11 h	jermar	/trunk/	memcpy(), memmove() and similar functions return dst instead of src. Fix all implementations, including those in assembly. ppc32 assembly version didn't seem to be affected by this.
