Subject: dmaengine: fsl-edma: dmatest timeout
Date: Tue, 28 Nov 2023 12:43:59 +0800	[thread overview]
Message-ID: <64cde245-0e53-6559-0a3b-ffe0a5415519@windriver.com> (raw)

Hi

When I executed the following command to do dmatest on the imx8qm platform,

I found that the timeout occurred on the current mainline kernel:


modprobe dmatest run=1 iterations=42


I found that the completion interrupt was not received in 
fsl_edma3_tx_handler().

I didn't find any special configuration from the manual. Can anyone give 
some suggestions?


thanks

xiaolei
