Where is MMU enabled?

the addresses that we give on the u-boot command line are physical addresses and not virtual, right (Thus implying MMU is not turned on?)? Or is it that kernel always gets the control with MMU on on PPC systems? How about other architectures? Thanks, Rick -- To unsubscribe from this list: send

2 PCI addresses for the PCI-PCI bridges?

Hi, AFAIK the PCI-PCI bridges are visible on two PCI buses (primary bus and secondary bus). Hence there ought to be two PCI addresses for the device - A.x.y and B.x.y, where A and B are primary and secondary bus numbers. Is this right? Thanks, Rick -- To unsubscribe from this list: send

What stops the vanialla kernel from being called an RTOS?

latency contradictory? I mean there will always be a tradeoff between the two. Any efforts to decrease on / make it predictable will increase / make unpredictable of the other. No? Thanks, Rick -- To unsubscribe from this list: send an email with unsubscribe kernelnewbies to ecar...@nl.linux.org

IRQF_TRIGGER_* flags

and most importantly, does my driver need to do anything differently depending upon whether the IRQ line is edge triggered or level triggered? And what does the kernel do differently for both the cases? TIA, Rick. -- To unsubscribe from this list: send an email with unsubscribe kernelnewbies to ecar

32 bit processors / 64 bit processors

can only be running a 32 bit OS. A 64 bit processor may run a 32 or a 64 bit OS. A 32 bit compiler genrates code only to be run on a 32 bit OS; ditto for 64 bit. Is this right? TIA, Rick -- To unsubscribe from this list: send an email with unsubscribe kernelnewbies to ecar...@nl.linux.org Please

MIssed interrupts

Hi, If a particual IRQ line has been disabled (disable_irq()), what happens if the device on that IRQ line generates interrupt? Does it result in missed interrupt? And in case of Uniprocessor machine, what happens if interrupts are generated while spinlock_irq_save() etc? TIA, Rick

Copy-on-Write
