Re: [PATCH] nv-1.0-8756 with Xen-3.0.1 on Fedora Core 5
D'oh. Forgot to mention that I had more unknown symbols that juste xen_tlb_flush.
force_evtchn_callback and xen_features are unknown as well to the nvidia driver, so I used the same method than with xen_tlb_flush to add them in the module.
I'm not familiar with kernel development, and have only little knowledge of C, but I'll try to add printk() where it makes sense as you suggests.
