Re: Does the Linux kernel for alpha support CONFIG_PREEMPT?

Darn - it was suggested that a performance issue I'm having with a Sil 3124 based pci-x esata card and a port multiplier might be helped with pre-emption enabled - just not for Alpha :)

I know that the DS20 often has PCI issues - anyone know of what may cause issues with a 64bit PCI-X card on the machine?

Any recommended placements for such thing?

I have 3 64 bit cards in the machine, a VIA gig ethernet, a combo scsi/ethernet card and the 3124-2 based eSata card ....

Are there patches available for Alpha in the case that it does not?

Not sure.  I do not see a PREEMPT option in the config file on my alpha
running Etch though, so I would suspect that it does not support preempt
at this time.  As for patches I have no idea.

Looking at the kernel source I see preempt included only by:
i386 mips parisc powerpc ppc x86_64
