4.14.124: 1 quad pipes, 1 z pipes initialized.
4.19.49: 1 quad pipes, 1 z pipes initialized.
4.20.17: 1 quad pipes, 1 z pipes initialized.

5.1.8: 1 quad pipes, 1 z pipes initialized.

Richard Thier, if we have the same graphic card then why do you sometimes get
"3 quad pipes, 1 z pipes initialized."? Can you test on different kernel

help further :)
