Subject: [PATCH] soc: fsl: dpio: Enable ACP port in Linux QMAN driver
|
||
|
|
|
||
|
|
Setting the software portal configuration DE(dequeue stashing
|
||
|
|
enable) bit. This should enable the ACP (Accelerator Coherency
|
||
|
|
Port).
|
||
|
|
|
||
|
|
During test this improved performance on the LS2088a slightly. No
|
||
|
|
effect on the LX2160a.
