This is v2 of an RFC sent earlier [1] to reduce power consumption of network PHYs with link that are either unused or the corresponding netdev is down.
In contrast to RFCv1, this now integrates phy_suspend/phy_resume transparent to the netdev drivers. Also, phy_suspend now only suspends the PHY if WOL is disabled. Moreover, the phy state machine calls phy_suspend on entering HALTED state. Again, a branch with RFCv2 applied to v3.13-rc2 can also be found at https://github.com/shesselba/linux-dove.git topic/ethphy-power-rfc-v2 [1] http://lwn.net/Articles/574426/ Sebastian Hesselbarth (6): net: mv643xx_eth: properly start/stop phy device net: phy: marvell: provide genphy suspend/resume net: phy: provide phy_resume/phy_suspend helpers net: phy: resume/suspend PHYs on attach/detach net: phy: suspend unused PHYs on mdio_bus in late_initcall net: phy: suspend phydev when going to HALTED drivers/net/ethernet/marvell/mv643xx_eth.c | 4 +++- drivers/net/phy/marvell.c | 22 ++++++++++++++++++++++ drivers/net/phy/mdio_bus.c | 25 +++++++++++++++++++++++++ drivers/net/phy/phy.c | 6 +++++- drivers/net/phy/phy_device.c | 27 +++++++++++++++++++++++++++ include/linux/phy.h | 2 ++ 6 files changed, 84 insertions(+), 2 deletions(-) --- Cc: David Miller <[email protected]> Cc: Florian Fainelli <[email protected]> Cc: Mugunthan V N <[email protected]> Cc: [email protected] Cc: [email protected] Cc: [email protected] -- 1.7.2.5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
