Hi Anuj,
Thanks for fixes!
I have 2 comments
- from i40e_ethdev.h : #define I40E_DEFAULT_RX_WTHRESH 0
- (26 + 32) / 4 (batched descriptor writeback) should be (26 + 4 * 32) / 4
(batched descriptor writeback)
, thus we have 135 bytes/packet
This corresponds to 58.8 Mpps

Hi,
I am wondering how can I use the hash library if I don't know the number of
entries in the bucket (number of entries in the bucket can grow dynamically)
I am trying to use the DPDK hash library for MAC table where I can't give the
fixed number of elements in each bucket.
Please let me know

In case with syn flood you should take into account return syn-ack traffic,
which generates PCIe DLLP's from NIC to host, thus pcie bandwith exceeds
faster. And don't forget about DLLP's generated by rx traffic, which
saturates host-to-NIC bus.

When compiling the cxgbe driver with icc, multiple errors about using
enums as integers appear across a number of files, including in the base
code and in the DPDK-specific driver code.

Yes, Bruce, we understand this. But we are working with huge SYN

Hi Pavel,
Looks like you ran into pcie bottleneck. So let's calculate xl710 rx only
case.
Assume we have 32byte descriptors (if we want more offload).
DMA makes one pcie transaction with packet payload, one descriptor
writeback and one memory request for free descriptors for every 4 packets.

Hi,
I have a requirement where one of my non-EAL app threads needs to
handoff some packets to an EAL task. I was thinking of using
rte_ring_mp_enqueue/dequeue for that purpose. I looked at the code for
the rte_ring library and it doesnt look like it has any "EAL"
dependencies, but I wanted to
Vladimir,
Few possible fixes to your PCIe analysis (let me know if I'm wrong):
- ECRC is probably disabled (check using sudo lspci -vvv | grep
CGenEn-), so TLP header is 26 bytes
- Descriptor writeback can be batched using high value of WTHRESH,
which is what DPDK uses by default
- Read request
The current way has a few problems:
- if cache->len < n, we copy our elements into the cache first, then
into obj_table, that's unnecessary
- if n >= cache_size (or the backfill fails), and we can't fulfil the
request from the ring alone, we don't try to combine with the cache
- if refill

Rahul's initial patch was pretty much what you have submitted, it just didn't

I submitted a patch for fixing this issue on the 25th of June. I did not
notice someone had reported this before. The last patch from Rahul does not
solve the problem. For those cases where the MSI-X table is in one of the
BARs to map, the memreg array is still in use.

Previously, with the -msse4.2 flag removed, the build failed for a different

I can retry without it and see if it's the case in the new DPDK.

GCC_VERSION is empty in case of clang:
/bin/sh: line 0: test: -ge: unary operator expected
It cannot be quoted because an integer is expected.
So the fix is to check empty value in a separate test.
