Hi Hiroshi, While still maintaining an old camera driver version, which uses your latest iommu driver, we have come up with the following question: Can the iommu driver be "consulted" if a certain area (contiguous or not) can be mapped or not, before even trying to do it? The reason of this is that, in the camera driver case, we want to let the user know if certain capture buffer area (that will be either allocated in kernel or userspace) can be mapped later on without problems, which could help the user don't even try to allocate the buffers, and avoid a trial-and-error kind of cycle. Is that possible with current driver? If not, how complex do you think it'll be to implement that?
