A build of recent DPDK 19.08 on all Ubuntu architectures returned this on ppc64:
../drivers/net/mlx4/mlx4_rxtx.c: In function ‘mlx4_tx_burst’:
../drivers/net/mlx4/mlx4_rxtx.c:919:14: error: incompatible types when
initializing type ‘__vector __bool int’ {aka ‘__vector(4) __bool int’}
using type ‘int’
919 | bool tso = txq->priv->tso && (buf->ol_flags & PKT_TX_TCP_SEG);
| ^~~
../drivers/net/mlx4/mlx4_rxtx.c:938:7: error: used vector type where scalar
is required
938 | if (tso) {
| ^~~
Which reminds everyone of the sad caps-lock story [1] which happened on 18.08.
Back then the fix was [2] and a discussion around ppc64 support state
happened, given that it wasn't even build-tested before release.
We might have to have the same discussion again, but for now I provided
the fix for the build fail on mlx4 implemented the same way as it was
done on mlx5 [2].
