Subject: Userspace interface breakage in power/state
Date: Mon, 16 Jan 2006 00:27:03 +0000 [thread overview]
Message-ID: <20060116002703.GA4769@srcf.ucam.org> (raw)
(Resent, without the wrong address for lkml)
In older kernels, power/state for PCI devices took a PCI power state as
an argument and so "3" was an entirely sensible thing to echo into it.
In current kernels, it hits a BUG() in pci_choose_state and things blow
up.
While I realise that the former interface was broken and wrong, would it
be possible to move to a new one without breaking existing code?
