[RFC PATCH] set current_state to D0 in register_slot
Hi all,
if a device doesn''t support power management (pm_cap == 0) but it is
acpi_pci_power_manageable() because there is a _PS0 method declared for
it and _EJ0 is also declared for the slot then nobody is going to set
current_state = PCI_D0 for this device. This is what I think it is
happening:
pci_enable_device
|
__pci_enable_device_flags
/* here we do not set current_state because !pm_cap */
|
do_pci_enable_device

pci_set_power_state...

Preventing hotplug devices in HVM guests
Hi there,
Is there a way to prevent Windows HVM guests from seeing passed through
devices like graphics cards as being ejectable?
i.e. you pass through a graphics adapter to an HVM guest which happens to
be Windows. Windows sees this as a device with hotplug capability.
Therefore it shows up in "safely remove hardware" option in the windows
system tray.
VMWare provides an option to
