[PATCH 0/4] Drivers: hv: vmbus: Make in-place consumption always possible

From: K. Y. Srinivasan Make in-place consumption of VMBus packets always possible. Currently we forbid it when a packet 'wraps around' the ring so we can't provide a single pointer to it. The idea if this series is dead simple: let's make a single virtual mapping for two copies (actually, two se

[PATCH 4/4] Drivers: hv: ring_buffer: count on wrap around mappings in get_next_pkt_raw()

From: Vitaly Kuznetsov With wrap around mappings in place we can always provide drivers with direct links to packets on the ring buffer, even when they wrap around. Do the required updates to get_next_pkt_raw()/put_pkt_raw() Signed-off-by: Vitaly Kuznetsov Signed-off-by: K. Y. Srinivasan Teste

[PATCH 3/4] Drivers: hv: ring_buffer: use wrap around mappings in hv_copy{from, to}_ringbuffer()

From: Vitaly Kuznetsov With wrap around mappings for ring buffers we can always use a single memcpy() to do the job. Signed-off-by: Vitaly Kuznetsov Signed-off-by: K. Y. Srinivasan Tested-by: Dexuan Cui --- drivers/hv/ring_buffer.c | 24 +++- 1 files changed, 3 insertio

[PATCH 1/4] Drivers: hv: cleanup vmbus_open() for wrap around mappings

From: Vitaly Kuznetsov In preparation for doing wrap around mappings for ring buffers cleanup vmbus_open() function: - check that ring sizes are PAGE_SIZE aligned (they are for all in-kernel drivers now); - kfree(open_info) on error only after we kzalloc() it (not an issue as it is valid to c

[PATCH 2/4] Drivers: hv: ring_buffer: wrap around mappings for ring buffers

From: Vitaly Kuznetsov Make it possible to always use a single memcpy() or to provide a direct link to a packet on the ring buffer by creating virtual mapping for two copies of the ring buffer with vmap(). Utilize currently empty hv_ringbuffer_cleanup() to do the unmap. While on it, replace size

[PATCH 1/1] Drivers: hv: Introduce a policy for controlling channel affinity

From: K. Y. Srinivasan Introduce a mechanism to control how channels will be affinitized. We will support two policies: 1. HV_BALANCED: All performance critical channels will be dstributed evenly amongst all the available NUMA nodes. Once the Node is assigned, we will assign the CPU based on a s

[PATCH 1/1] Tools: hv: kvp: ensure kvp device fd is closed on exec

From: Vitaly Kuznetsov KVP daemon does fork()/exec() (with popen()) so we need to close our fds to avoid sharing them with child processes. The immediate implication of not doing so I see is SELinux complaining about 'ip' trying to access '/dev/vmbus/hv_kvp'. Signed-off-by: Vitaly Kuznetsov Sig
