ttg::device::Input can be filled with buffers and passed to ttg::device::select(). Signed-off-by: Joseph Schuchart <[email protected]>
Set the flow to read-only at the end of the task for flows that are marked as temporary. This allows PaRSEC to put the data into a read-only queue that does not need to be pushed back to the host. Temporary data does not need to be evicted, only released. Signed-off-by: Joseph Schuchart <[email protected]>

PaRSEC will try to remove a reader from the resulting read-only flow. Signed-off-by: Joseph Schuchart <[email protected]>
If the flow is only WRITE we don't want to add the READ flag. Signed-off-by: Joseph Schuchart <[email protected]>

Empty buffers are always valid on the current device. Signed-off-by: Joseph Schuchart <[email protected]>

This allows querying whether the buffer is current on the given device. Also add a note that Buffer::current_device() cannot reflect the fact that all devices may have the current data (e.g., after a pushout). Also add static ttg::device::Device::host() that returns the host device. Signed-off-by: Joseph Schuchart <[email protected]>

The code path for no-arg callables was missing a return and we have to specify template arguments for std::array explicitly because the array could be empty. Signed-off-by: Joseph Schuchart <[email protected]>

Next set of changes needed for MRA. This change set allows buffers to be empty and const and enables tasks to define a flexible set of device inputs using
ttg::device::Input, which is a vector of buffers internals provided by the backend implementation.
