[RFC][PATCH 0/2] PCI PM: Fix radeonfb vs pci_set_power_state() problem

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

The following two patches are intended to fix the problem that will arise
when the PM patches queued up for 2.6.30 are merged and which is that
pci_set_power_state() called by radeonfb to complete the transition into D2
will return immediately due to the device's current_state being already PCI_D2.

1/2 introduces low level PM core functions one of which may be called by the
radeonfb driver to complete the power transition.

2/2 actually makes radeonfb use the new function.

The patches (on top of the linux-next branch of suspend-2.6) have not been
tested yet, but they compile (at least on x86_64).

Comments welcome.

Thanks,
Rafael
