2017-06-01drm/exynos: mixer: simplify mixer_cfg_rgb_fmt()Tobias Jakobi1-22/+8

2017-06-01drm/exynos/dsi: fix bridge_node DT parsingAndrzej Hajda1-1/+1
DSIM uses MIC bridge which is between DECON and DSIM, so the driver should expect bridge node on input side. Fixes: 86418f9 ("drm: convert drivers to use of_graph_get_remote_node") Signed-off-by: Andrzej Hajda <a.hajda@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2017-06-01drm/exynos/hdmi: fix pipeline disable orderAndrzej Hajda1-10/+3
Hardware require that MIXER(crtc) should be disabled prior to HDMI(encoder). It was achieved by disabling crtc from encoder disable callback, bypassing drm core. As a result drm core tried to call vblank related routines on disabled crtc. The patch fixes it by simplifying hdmi_disable routine - now it only cancels hotplug worker. Hardware will be disabled in proper moment during pipe clock disable. Signed-off-by: Andrzej Hajda <a.hajda@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>

2017-05-26drm/i915: Keep the forcewake timer alive for 1ms past the most recent useChris Wilson2-3/+13
Currently the timer is armed for 1ms after the first use and is killed immediately, dropping the forcewake as early as possible. However, for very frequent operations the forcewake dance has a large impact on latency and keeping the timer alive until we are idle is preferred. To achieve this, if we call intel_uncore_forcewake_get whilst the timer is alive (repeated use), then set a flag to restart the timer on expiry rather than drop the forcewake usage count. The timer is racy, the consequence of the race is to expire the timer earlier than is now desired but does not impact on correct behaviour. The offset the race slightly, we set the active flag again on intel_uncore_forcewake_put. The effect should be to reduce the jitter of reacquiring the fw every 1ms on a busy system. However, the cost is to keep the timer alive for an extra 1ms on a nearly idle system. We chose to incur the jitter previously to keep the timer off for as much as possible.

2017-05-26nvme: only setup block integrity if supported by the driverChristoph Hellwig3-19/+33
Currently only the PCIe driver supports metadata, so we should not claim integrity support for the other drivers. This prevents nasty crashes with targets that advertise metadata support on fabrics. Also use the opportunity to factor out some code into a separate helper that isn't even compiled if CONFIG_BLK_DEV_INTEGRITY is disabled.

2017-05-25bonding: Don't update slave->link until ready to commitNithin Sujir1-2/+9
In the loadbalance arp monitoring scheme, when a slave link change is detected, the slave->link is immediately updated and slave_state_changed is set. Later down the function, the rtnl_lock is acquired and the changes are committed, updating the bond link state. However, the acquisition of the rtnl_lock can fail. The next time the monitor runs, since slave->link is already updated, it determines that link is unchanged. This results in the bond link state permanently out of sync with the slave link. This patch modifies bond_loadbalance_arp_mon() to handle link changes identical to bond_ab_arp_{inspect/commit}(). The new link state is maintained in slave->new_link until we're ready to commit at which point it's copied into slave->link. NOTE: miimon_{inspect/commit}() has a more complex state machine requiring the use of the bond_{propose,commit}_link_state() functions which maintains the intermediate state in slave->link_new_state. The arp monitors don't require that. Testing: This bug is very easy to reproduce with the following steps. 1. In a loop, toggle a slave link of a bond slave interface. 2. In a separate loop, do ifconfig up/down of an unrelated interface to create contention for rtnl_lock. Within a few iterations, the bond link goes out of sync with the slave link.
