Linux kernel 6.5.0 support #59

Open klogg opened 8 months ago

klogg commented 8 months ago

Implemented with compile checks only in 0c87d7c. Need testing on the hardware

ftoledo commented 7 months ago

can you add support for 6.1 too?

Please provide (attach) your kernel config. On running system you can do it like described here

From the first glance, you have CONFIG_DRM_GEM_DMA_HELPER disabled in your kernel

ftoledo commented 6 months ago

hi @klogg

seem to are disabled on debian:

cat /boot/config-6.5.0-0.deb12.4-amd64 |grep CONFIG_DRM_GEM_DMA_HELPER return empty

klogg commented 6 months ago

Sorry, this is needed for the driver... Can you rebuild the kernel for test?
