PBL should be limited to half of the Queue size. For multi-queue: Total MTL queue size 4KB. PBL = 16, PBLx8 = 1 -> This setting would lead to an effective burst = 8*16 = 128, which would mean 128*16B = 2KB (half of queue size) Signed-off-by: Bhadram Varka <vbhadram@xxxxxxxxxx> --- arch/arm64/boot/dts/nvidia/tegra186.dtsi | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm64/boot/dts/nvidia/tegra186.dtsi b/arch/arm64/boot/dts/nvidia/tegra186.dtsi index 48c6caf..c4d70c5 100644 --- a/arch/arm64/boot/dts/nvidia/tegra186.dtsi +++ b/arch/arm64/boot/dts/nvidia/tegra186.dtsi @@ -101,7 +101,7 @@ snps,write-requests = <1>; snps,read-requests = <3>; snps,burst-map = <0x7>; - snps,txpbl = <32>; + snps,txpbl = <16>; snps,rxpbl = <8>; snps,mtl-rx-config = <&mtl_rx_setup>; snps,mtl-tx-config = <&mtl_tx_setup>; -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
