I'm having this output

usage: vramfs <mountdir> <size> [-d <device>] [-f]

  mountdir    - directory to mount file system, must be empty
  size        - size of the disk in bytes
  -d <device> - specifies identifier of device to use
  -f          - flag that forces mounting, with a smaller size if needed

The size may be followed by one of the following multiplicative suffixes: K=1024, KB=1000, M=1024*1024, MB=1000*1000, G=1024*1024*1024, GB=1000*1000*1000. It's rounded up to the nearest multiple of the block size.

looks like you’re trying to use vramfs with integrated gpu, while it’s made for discrete ones. igpus tend to use a part of ram as vram, so vramfs is kinda pointless here and will be a useless bridge to actual ram, but through gpu. better use ramfs then.

sorry for being late, but it’s better than never ;)
