Hello nvidia experts:
I found this page( nvdisplay ) for Refresh rate setup in nvdisplay for DP-SERIALIZER-0:
\ {
display@13800000 {
display-timings {
display-connector-0 {
dcb-index = <0>;
stream-0 {
timings-phandle = <&mode0>;
};
stream-1 {
timings-phandle = <&mode1>;
};
};
};
mode0: 1920-1080-60Hz {
clock-frequency-khz = <148500>;
hactive = <1920>;
vactive = <1080>;
hfront-porch = <88>;
hback-porch = <148>;
hsync-len = <44>;
vfront-porch = <4>;
vback-porch = <36>;
vsync-len = <5>;
rrx1k = <60000>;
pps-data = [
11 00 00 89 30 80 04 38
07 80 04 38 03 c0 03 c0
02 00 03 58 00 20 73 3e
00 0d 00 0f 00 1d 00 0e
18 00 10 f0 03 0c 20 00
06 0b 0b 33 0e 1c 2a 38
46 54 62 69 70 77 79 7b
7d 7e 01 02 01 00 09 40

1a 38 1a 78 22 b6 2a b6
2a f6 2a f4 43 34 63 74
00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 ];
};
mode1: 1280-720-60Hz {
clock-frequency-khz = <74250>;
hactive = <1280>;
vactive = <720>;
hfront-porch = <110>;
hback-porch = <220>;
hsync-len = <40>;
vfront-porch = <5>;
vback-porch = <20>;
vsync-len = <5>;
rrx1k = <60000>;
};
};
};
So I changed mode0&mode1 to 1920-1080-30Hz 1280-720-30Hz and set rrx1k to 30000.
While after start up X server with below command:
sudo insmod /lib/modules/$(uname -r)/extra/opensrc-disp/nvidia.ko rm_firmware_active=“all”
sudo insmod /lib/modules/$(uname -r)/extra/opensrc-disp/nvidia-modeset.ko
sudo X -ac -noreset -nolisten tcp &
xrandr output still shows it runs in 60 Refresh rate:
DP-SERIALIZER-0 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1920x1080 60.00*+
And I also tried to use nvidia-drm with below command :
sudo modprobe nvidia-drm modeset=1
The dmesg shows nvidia-drm just add one line:
[drm:drm_mode_debug_printmodeline] Modeline “1920x1080”: 60 148500 1920 2008 2052 2200 1080 1084 1089 1125 0x0 0x5
drm modes shows it only has one option:
cat /sys/class/drm/card0-DP-1/modes:
1920x1080
So how should the Refresh rate be changed for nvidisplay? Should this be done through device-tree configuration, or through application(X server, xrandr --newmode) ?
