The LOGINIT, LOGINTR, LOGRM, and LOGPMU buffers are circular buffers that have printf-like logs from GSP-RM and PMU encoded in them. LOGINIT, LOGINTR, and LOGRM are allocated by Nouveau and their DMA addresses are passed to GSP-RM during initialization. The buffers are required for GSP-RM to initialize properly. LOGP...

...memset(d, 0, sizeof(*d)); return PTR_ERR(dir); } The one thing I could do is that is ignore errors from r535_gsp_copy_log(), and just blindly try to create all logs even if some of them fail. I can't imagine a situation where create the loginit debugfs entry could fail, but then creating logintr succeeds. > > > In fact, I think I found a small bug in dput(): > > > > void dput(struct dentry *dentry) > > { > > if (!dentry) > > return; > > > > This should probably be "if (IS_ERR_OR_NULL(dentry))". > > Yes, I agree, goo...
