Re: [Xen-devel] no-carrier on qlogic 8242 10gig with linux 3.x running xen

[Kristoffer Harthing Egefelt <k@xxxxxxx>]

Diffing the dmesg's from native linux 3.x and linux 3.x with xen shows 4 more
lines on the native:

Native:
 qlcnic 0000:03:00.0: phy port: 0 switch_mode: 0,
    max_tx_q: 1 max_rx_q: 8 min_tx_bw: 0x0,
    max_tx_bw: 0x64 max_mtu:0x2580, capabilities: 0x6affae
 qlcnic 0000:03:00.0: failed card response code:0x10
 qlcnic 0000:03:00.0: Can't get template size 16
 qlcnic 0000:03:00.0: firmware v4.7.83
 qlcnic: 24:b6:fd:64:1e:45: QME8242-k 10GbE Dual Port Mezzanine Card Board
Chip rev 0x54
* qlcnic 0000:03:00.0: irq 78 for MSI/MSI-X
 qlcnic 0000:03:00.0: irq 79 for MSI/MSI-X
 qlcnic 0000:03:00.0: irq 80 for MSI/MSI-X
 qlcnic 0000:03:00.0: irq 81 for MSI/MSI-X*
 qlcnic 0000:03:00.0: using msi-x interrupts
 qlcnic 0000:03:00.0: eth0: XGbE port initialized

The xen version of dmesg does not have these irq's:

XEN:
 qlcnic 0000:03:00.0: phy port: 0 switch_mode: 0,
    max_tx_q: 1 max_rx_q: 8 min_tx_bw: 0x0,
    max_tx_bw: 0x64 max_mtu:0x2580, capabilities: 0x6affae
 qlcnic 0000:03:00.0: failed card response code:0x10
 qlcnic 0000:03:00.0: Can't get template size 16
 qlcnic 0000:03:00.0: firmware v4.7.83
 qlcnic: 24:b6:fd:64:1e:45: QME8242-k 10GbE Dual Port Mezzanine Card Board
Chip rev 0x54
 qlcnic 0000:03:00.0: using msi-x interrupts
 qlcnic 0000:03:00.0: eth0: XGbE port initialized
 xen: registering gsi 38 triggering 0 polarity 1
 xen_map_pirq_gsi: returning irq 38 for gsi 38
 xen: --> pirq=38 -> irq=38 (gsi=38)
 Already setup the GSI :38

Does this make any sense?
I'm able to mod probe the qlcnic driver with options:
use_msi=0 and
use_msi_x=0
but this has no effect.
