Subject: [PATCH] vc4/drm: Increase hdmi audio axi priority to avoid
|
|
lost samples
|
|
|
|
With HBR audio (8 channel 192kHz) we get occasional VC4_HD_MAI_CTL_DLATE error flags in
|
|
HDMI_MAI_CTL which seem to correspond with audio dropouts.
|
|
|
|
Increasing the normal AXI priority for dma is needed to avoid these
