I guess this is really talking about requirements of a specific CPU/SOC before it will enter S0i3.2? > Also fixed a typo in the previous commit 632fbd5eb5b0 > ("e1000e: fix S0ix flows for cable connected case").

Maybe the commit log for the fix should mention that it's fixing a regression, what the regression was, and include a Fixes: tag? But not my circus. > Signed-off-by: Vitaly Lifshits <vitaly.lifshits@intel.com> > Tested-by: Aaron Brown <aaron.f.brown@intel.com> > Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com> > --- > drivers/net/ethernet/intel/e1000e/netdev.c | 8 ++++---- > 1 file changed, 4 insertions(+), 4 deletions(-) > > diff --git a/drivers/net/ethernet/intel/e1000e/netdev.c b/drivers/net/ethernet/intel/e1000e/netdev.c > index b30f00891c03..128ab6898070 100644 > --- a/drivers/net/ethernet/intel/e1000e/netdev.c > +++ b/drivers/net/ethernet/intel/e1000e/netdev.c > @@ -6475,13 +6475,13 @@ static void e1000e_s0ix_entry_flow(struct e1000_adapter *adapter) > > /* Ungate PGCB clock */ > mac_data = er32(FEXTNVM9); > - mac_data |= BIT(28); > + mac_data &= ~BIT(28); > ew32(FEXTNVM9, mac_data); > > /* Enable K1 off to enable mPHY Power Gating */ > mac_data = er32(FEXTNVM6); > mac_data |= BIT(31); > - ew32(FEXTNVM12, mac_data); > + ew32(FEXTNVM6, mac_data); > > /* Enable mPHY power gating for any link and speed */ > mac_data = er32(FEXTNVM8); > @@ -6525,11 +6525,11 @@ static void e1000e_s0ix_exit_flow(struct e1000_adapter *adapter) > /* Disable K1 off */ > mac_data = er32(FEXTNVM6); > mac_data &= ~BIT(31); > - ew32(FEXTNVM12, mac_data); > + ew32(FEXTNVM6, mac_data); > > /* Disable Ungate PGCB clock */ > mac_data = er32(FEXTNVM9); > - mac_data &= ~BIT(28); > + mac_data |= BIT(28); > ew32(FEXTNVM9, mac_data); > > /* Cancel not waking from dynamic > -- > 2.25.1 >
