Hi, Next update: v7: - remove documentation update to be send separately - address comments from Mathieu Poirier (thanks) v6: - rename include/linux/virtio_rpmsg.h -> include/linux/rpmsg/virtio.h v5: - don't hard-code message layout v4: - add endianness conversions to comply with the VirtIO standard v3: - address several checkpatch warnings - address comments from Mathieu Poirier v2:

Dear R-Community, I am relatively new with R, so sorry for things which for you might be obvious... I am trying to automatically update lmer formulae. the variables of the model are: depM= my dependent measure Sb2= a random factor OS = a predictor VR= another predictor So, I am building the first model with random intercept only: model = lmer(depM ~ (1 |Sb2)) then I update the formula adding the first predictor model1 = update(model, as.formula(paste(". ~ . + ", OS))) the resulting formula will be: depM ~ (1 |Sb2) + OS let supp...

Changes from v2: added padding between avail idx and flags, and changed virtio to only publish used index when callbacks are enabled. Here's a rewrite of the original patch with a new layout. I haven't tested it yet so no idea how this performs, but I think this addresses the cache bounce issue raised by Avi. Posting for early flames/comments. Generally, the Host end of the virtio ring
