HD resolution not getting enabled - log message with drm.debug=0x06
I am currently working on an embedded project using Minnowboard max. I
have builded a customized Linux kernel-v4.4 and using u-boot (latest
version) as Boot loader.
The VESA driver in the u-boot takes more time to initialize,so I have
disabled it. I am passing the kernel parameters "video=" to enable the
HDMI port to which a monitor is connected.
The monitor is connected via HDMI-DVI cable
The video parameter arguments "video=HDMI-A-1:1920x1200@60mD
video=VGA-1:d video=DP-1:d"
>From the dmesg I got to know that the 1920x1200 is not getting
supported or there is some probing issue
[ 2.922671] [drm:drm_mode_prune_invalid] Not using 1920x1200 mode:
CLOCK_HIGH
and the resolution is set to '1024x768'
[ 3.153392] [drm:intel_dump_pipe_config] adjusted mode:
[ 3.153399] [drm:drm_mode_debug_printmodeline] Modeline
0:"1024x768" 60 65000 1024 1048 1184 1344 768 771 777 806 0x40 0
Do you have any idea why this is happening ?. I have attached the dmesg logs -
HD_resolution_not_working.txt
With no video parameters passed , I am seeing that the display is not coming
up.
Please note that in both cases if I enable the VESA driver in the u-boot its
working fine.</pre>
