From 40799ca446bed8dcb0bfc667fafb1c3a20f88b87 Mon Sep 17 00:00:00 2001 From: Dom Cobley Date: Fri, 12 Mar 2021 11:26:29 +0000 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 Signed-off-by: Dom Cobley --- arch/arm/boot/dts/bcm2711-rpi.dtsi | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) --- a/arch/arm/boot/dts/bcm2711-rpi.dtsi +++ b/arch/arm/boot/dts/bcm2711-rpi.dtsi @@ -179,7 +179,7 @@ }; &hdmi0 { - dmas = <&dma (10|(1<<27)|(1<<24)|(0<<16)|(15<<20))>; + dmas = <&dma (10|(1<<27)|(1<<24)|(10<<16)|(15<<20))>; status = "disabled"; }; @@ -188,7 +188,7 @@ }; &hdmi1 { - dmas = <&dma (17|(1<<27)|(1<<24)|(0<<16)|(15<<20))>; + dmas = <&dma (17|(1<<27)|(1<<24)|(10<<16)|(15<<20))>; status = "disabled"; };
