Keep a size limited list with error cookies and flush them in terminate all?I think so, terminate_all anyway cleans up the channel. Btw what is the behaviour on error? Do you terminate or somthing else?
On error, I flush all outstanding transactions with an error code and I reset the channel. After the reset, the DMA channel is functional again. The client doesn't need to shutdown anything. -- Sinan Kaya Qualcomm Datacenter Technologies, Inc. as an affiliate of Qualcomm Technologies, Inc.
