Subject: barriers vs I/O and DMA for ia64
Date: Tue, 31 Jul 2018 19:20:30 +0200 [thread overview]
Message-ID: <20180731172031.4447-1-hch@lst.de> (raw)
Hi all,
please review these patches carefully - ia64 currenly seems to be
the odd one out in terms of barrier placement for DMA and I/O and
this patch tries to resolve it. But I don't have any IA64 hardware
nor do I know the architecture to well, so don't blindly trust me.
