800x1280_50 will not make

[StickyDigit]

I use 50Hz for video as I'm in the UK... not a native rate on my Linx 1010B fondle-slab. For xorg, I used to use a simple script with xrandr, and for Wayland shove the modeline in the sway config, but it seems both fail in recent kernels.

So.. I tried to use edid-generator to generate the edid file like this.

First, generate the modeline exactly as I'd done for the previously working xrandr

$ cvt 800 1280 50 
# 800x1280 49.82 Hz (CVT) hsync: 65.76 kHz; pclk: 70.50 MHz
Modeline "800x1280_50.00"   70.50  800 856 936 1072  1280 1283 1293 1320 -hsync +vsync

Which with aspect ratio added becomes...

Modeline "800x1280_50.00"   70.50  800 856 936 1072  1280 1283 1293 1320 -hsync +vsync ratio=10:16

Which modeline2edid seems to grok just fine.

Make though, breaks.

$ make 
cc -c -DCRC="0x00" -o 800x1280_50.00.o 800x1280_50.00.S
edid.S: Assembler messages:

make: *** [Makefile:16: 800x1280_50.00.o] Error 1

1280x800_50 builds fine, but this fondle-slab needs portrait definitions.

same here but with 800x480@60 display in manjaro ARM

Modeline "800x480_60.00" 29.50 800 824 896 992 480 483 493 500 -hsync +vsync ratio=5:3

[sl1pkn07]

i think i know the culprit. 10:16 or 5:3 is "not valid" ratio for edid.S

in you case. seems a typo, should be 16:10, but in my case, 5:3 not exisat in the implementation

anyone know how add it? 800x480 is a commonly used for rpi/movile devices
