2021-05-01vlib: refactor trajectory trace debug featureBenoît Ganne1-1/+0
trajectory trace has been broken for a while because we used to save the buffer trajectory in a vector pointed to in opaque2. This does not work well when opaque2 is copied (eg. because of a clone) as 2 buffers end up sharing the same vector. This dedicates a full cacheline in the buffer metadata instead when trajectory is compiled in. No dynamic allocation, no sharing, no tears.

2020-09-16vmxnet3: gso fixesSteven Luong1-5/+13
outbound: wrong header len computation gso size and header length need to be set in the first segment of the chain inbound: EOP may have zero length descriptor to terminate the chain missing endian conversion for ethertype Type: fix Signed-off-by: Steven Luong <sluong@cisco.com> Change-Id: Iaa003c0e9af3ead4df6c6c0d5772a179d2ff15c4
2019-08-30vmxnet3: per interface gso supportSteven Luong1-1/+1
gso option for vmxnet3 is per VPP process currently. There is no reason why we cannot provide per interface gso support. Type: feature Signed-off-by: Steven Luong <sluong@cisco.com> Change-Id: Ife962b52221191050dedd18252b859880ccd7599
2019-02-26vmxnet3: lro/tso and rx checksumSteven Luong1-4/+22
Add lro/tso and rx checksum support. lro/tso is configured via startup.conf vmxnet3 { lro } It is disable by default due to not all versions of ESXi supports it. Change-Id: Icf224ff528884ecd9e655b4fcf4481194e8c5a63 Signed-off-by: Steven Luong <sluong@cisco.com>
2019-02-02vmxnet3: multiple TX queues supportSteven Luong1-5/+3
Add num-tx-queues to the vmxnet3 create CLI/API. Default is 1. Max is min (8, the number of cores assigned to VPP). Change-Id: I7e0a659a82d01c719665c228dd8a71e3288a2895 Signed-off-by: Steven Luong <sluong@cisco.com>
2018-11-13vlib rename vlib_frame_args(...) to vlib_frame_scalar_args(..)Damjan Marion1-1/+1
Typically we have scalar_size == 0, so it doesn't matter but vlib_frame_args was providing pointer to scalar frame data, not vector data. To avoid future confusion function is renamed to vlib_frame_scalar_args(...) Change-Id: I48b75523b46d487feea24f3f3cb10c528dde516f Signed-off-by: Damjan Marion <damarion@cisco.com>
2018-11-07vmxnet3: reduce calling vmxnet3_reg_write_inlineSteven1-4/+7
In output.c, we buffer the descriptors and call vmxnet3_reg_write_inline once outside the loop. This change improves the performance dramatically. When refilling the ring, there is no need to inform the device unless explicitly specified by the device (ctrl.update_prod == 1) Change-Id: I7031d58bff0d249e913d14236d416c91eb6ab94a Signed-off-by: Steven <sluong@cisco.com>
2018-10-27vmxnet3: add logging support to the control plane [VPP-1470]Steven1-1/+2
There are different flavors of vmxnet3 device, esxi server, vm fusion, vmware workstation, and vmware player, that we need to communicate with. Each of them also has different versions. We really need the control plane logging to debug when things don't work as expected. Change-Id: I53c23cf10958bfbc06abb1c252d368003563cd04 Signed-off-by: Steven <sluong@cisco.com>

2018-10-10vmxnet3: better error handlingSteven1-9/+16
try harder on output - if there is no descriptor space available, try to free up some and check again. make sure we free the buffer if error is encoutered on input. Change-Id: I41a45213e29de71935afe707889e515037cd081f Signed-off-by: Steven <sluong@cisco.com>
2018-10-03vmxnet3: coverity woeSteven1-9/+6
Coverity complains that hb might be null when !prev_b0 is true. It may be right, but not likely. To make the code more explicit when it parses a complete packet, set got_packet = 1 and test got_packet instead of prev_b0 which is somewhat obscure. Use vlib_buffer_free_one rather than vlib_buffer_free_no_next in output.c which takes care of chain buffers.

2018-10-03vmxnet3: error handlingSteven1-41/+38
outbound -- if we have to drop the packet due to no descriptor space is available, drop the whole packet, not fragments. inbound -- check and drop error packets Change-Id: Ida1d32e61521bafd67f714d729ad53cd7c487dc6 Signed-off-by: Steven <sluong@cisco.com>
