evdi module does not compile with Linux kernel 6.6.8-x
I'm using DisplayLink for Ubuntu V5.8 on Siduction Linux, a rolling Debian distribution.
This worked for me until kernel 6.5.12-1, beside the slow refresh problem, which does not interfere with my slow GUI application on the DisplayLink monitor. Now with kernel 6.6.8-x, the DisplayLink evdi module fails to compile, so I cant use these kernel versions. I searched and found, that /var/lib/dkms/evdi/1.14.1/build/make.log tells about missing functions drm_gem_prime_fd_to_handle and drm_gem_prime_handle_to_fd. The header file /usr/src/linux-headers-6.5.0-5-common/include/drm/drm_prime.h contains definitions of these functions, whereas /usr/src/linux-headers-6.6.8-common/include/drm/drm_prime.h does not list these functions anymore. I'm an occasional programmer, and kernel programming is far above my skills, so I cant tell if this is a bug or a feature. Please take this information as a warning about future (Ubuntu) kernel versions. |
Hello,
I have the same problem on a Debian SID with kernel 6.6.x. Is an upgrade planned? |
This works by placing the dev version of EVDI in the standalone installer.
