Subject: Re: [PATCH] ppc64: create dma_mapping_error
Date: 02 Apr 2004 11:33:34 -0500 [thread overview]
Message-ID: <1080923616.1829.73.camel@mulgrave> (raw)
What exactly are you guys doing?
The API Anton introduced: dma_mapping_error() takes only a virtual
address as the argument (no struct device or anyting), so the additional
API's pci_dma_mapping_error() and vio_dma_mapping_error have absolutely
no choice but to do the same thing as dma_mapping_error() (because the
error return cannot be bus or device specific).
So, why bother introducing all these superfluous APIs in the first
place? Just stick to the single dma_mapping_error(); it will be much
easier.
James
