info_enable is not followed on module load/unload #63

Closed trosenkranz closed 3 years ago

trosenkranz commented 3 years ago

hello,

i build u-dma-buf on Ubuntu 20.04 LTS and loaded the module with sudo insmod u-dma-buf.ko udmabuf0=8388608 and observed, that there was no output on the commandline of any kind.

i checked with systool and confirmed, that info_enable is set to 1.

greetings

Thank you for the issue.

The infomation of udmabuf is output to the kernel log. What is the output of dmesg?

trosenkranz commented 3 years ago

thanks, just observed that myself.

i interpreted the readme that way, that it is logged to the console too. maybe you should clearify that.

thanks and have a nice and healthy day tobias
