The tulip driver fails to initialize in a Linux VM running on Hyper-V.
The following messages are logged in syslog when trying to load the tulip
driver:
tulip: Linux Tulip drivers version 1.1.15 (Feb 27, 2007)
tulip: 0000:00:0a.0: PCI INT A: failed to register GSI
tulip: Cannot enable tulip board #0, aborting
tulip: probe of 0000:00:0a.0 failed with error -16
The tulip drivers initialization function tulip_init_one() calls
pci_enable_device(). The call to pci_enable_device() eventually
results in a call to alloc_isa_irq_from_domain(), which returns -EBUSY (-16)
The message "tulip: 0000:00:0a.0: PCI INT A: failed to register GSI" is
logged by acpi_pci_irq_enable().
The flow of calls to the error is returned is:
acpi_pci_irq_enable() - Logs the message "PCI INT A: failed to register GSI"
acpi_register_gsi()
__acpi_register_gsi() is afunction pointer -> acpi_register_gsi_ioapic()
acpi_register_gsi_ioapic()
mp_map_gsi_to_irq()
mp_map_ppin_to_irq()
alloc_isa_irq_from_domain()
Returning -EBUSY when mp_check_pin_attr() returns false.
mp_check_pin_attr()
data->trigger = 1
data->polarity = 0
info->ioapic_trigger = 1
info->ioapic_polarity = 1
mp_check_pin_attr() returns false because the two polarity values do
not match.
acpi_register_gsi_ioapic() is setting trigger and polarity to:
trigger = 1
polarity = 1
mp_check_pin_attr() is calling irq_get_chip_data(irq) which is returning a
mp_chip_data structure with
trigger = 1
polarity = 0
Since the two polarity values do not match, mp_check_pin_attr() returns false.
Broken in 3.19.0 kernel
Works in 3.17 kernel.

Title:
[Hyper-V] Legacy network adapter is not detected
Status in linux package in Ubuntu:
Confirmed
Bug description:
Issue description:
Attaching a Legacy network adapter to a VM will not be detected on the VM
side.
This is not the case with synthetic adapters, which are properly identified.
Steps to Reproduce:
1. Add a Legacy Network adapter to the VM
2. Boot the vm
3. Verify the identified network adapter, the legacy NIC is missing
Versions details:
Windows Server Host Edition: Microsoft Windows Server 2012 R2 Datacenter
build 9600 and Microsoft Windows Server 2008 R2 Standard SP 1 build 7601
Distribution name and release: Ubuntu Vivid Vervet
Kernel version: Linux ubuntu31 3.19.0-11-generic #11lp14233432v201504021617
SMP
Hyper-V side:
PS> Get-VMNetworkAdapter -VMName vivid1
Name IsManagementOs VMName SwitchName MacAddress Status
IPAddresses
---- -------------- ------ ---------- ---------- ------
-----------
Network Adapter False vivid1 external 00155D06332D {Ok}
{IP, fe80::215:5dff:fe06:332d}
Legacy Network Adapter False vivid1 external 00155D063336 {Ok} {}
On the VM Side:
root@ubuntu31:~# ls /sys/class/net/
eth0 lo
eth0 has the MAC of the Network Adapter, which is the synthetic
interface.
This has been verified with also 1 vCPU or with irqbalancer daemon disabled,
as that is a common requirements when using legacy adapters.
