Hi Benjamin, Tested this on top of 6.1-rc1 against my HID-USI work, appears to be good. Also tried out the HID selftests, and they pass, so for the whole series: Tested-by: Tero Kristo <tero.kristo@linux.intel.com> On 25/10/2022 12:34, Benjamin Tissoires wrote: > Hi, > > and here comes the v11 of the HID-BPF series. > > Again, for a full explanation of HID-BPF, please refer to the last patch > in this series (14/14). > > Now that the bpf-core changes are all merged in v6.1, it is > time to have that series entirely relying on HID, so it can get > merged into the HID tree. > > Compared to v10, the most notable change is in the selftests and the > samples: they are now namespaced into hid, not bpf. > > This means that HID-BPF has no more conflicts with the bpf tree. > > One other interesting change is in patch 4/14.
