2019-10-22drm/i915/selftests: Make the mman object busy everywhereChris Wilson
Loop over all engines, issuing a request for the object on each in order to make sure we leave no stone unturned when creating an active ref. The purpose is to make sure that we can reap a zombie object (one that is only alive due to an active reference on the GPU) no matter where that active reference emanates from.

2019-10-21drm/i915/gt: Introduce barrier pulses along enginesChris Wilson
To flush idle barriers, and even inflight requests, we want to send a preemptive 'pulse' along an engine. We use a no-op request along the pinned kernel_context at high priority so that it should run or else kick off the stuck requests. We can use this to ensure idle barriers are immediately flushed, as part of a context cancellation mechanism, or as part of a heartbeat mechanism to detect and reset a stuck GPU.

In this situation, we elide the tasklet rescheduling and should *not* be marking up the queue_priority_hint as that may mask a later submission where we decide we don't have to kick the tasklet as a higher priority submission is pending (spoiler alert, it was not).

2019-10-19net: reorder 'struct net' fields to avoid false sharingEric Dumazet
Intel test robot reported a ~7% regression on TCP_CRR tests that they bisected to the cited commit. Indeed, every time a new TCP socket is created or deleted, the atomic counter net->count is touched (via get_net(net) and put_net(net) calls) So cpus might have to reload a contended cache line in net_hash_mix(net) calls. We need to reorder 'struct net' fields to move @hash_mix in a read mostly cache line. We move in the first cache line fields that can be dirtied often. We probably will have to address in a followup patch the __randomize_layout that was added in linux-4.13, since this might break our placement choices.

Jakub Kicinski says: ==================== net: netem: fix further issues with packet corruption This set is fixing two more issues with the netem packet corruption. First patch (which was previously posted) avoids NULL pointer dereference if the first frame gets freed due to allocation or checksum failure. v2 improves the clarity of the code a little as requested by Cong. Second patch ensures we don't return SUCCESS if the frame was in fact dropped. Thanks to this commit message for patch 1 no longer needs the "this will still break with a single-frame failure" disclaimer. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
