I have a Forlinx OKA40i-C development board that has an arm R40 as its Soc.
I use the latest Linux kernel (5.14.2 that contains "lima" for mali400 GPU ) and the latest Debian (11 aka bullseye that contains mesa project).
but when I want to use GPU, like run the "kmscube" command I encounter this error
DRM_IOCTL_MODE_CREATE_DUMB failed: Cannot allocate memory
if you know anybody that can help me with this problem, please please introduce him/her to me.
ps. I checked the #linux-sunxi channel that you suggested, nobody help me.
I desperately need your help.
