2018-11-23drm/atomic-helper: Complete fake_commit->flip_done potentially earlierVille Syrjälä
Consider the following scenario: 1. nonblocking enable crtc 2. wait for the event 3. nonblocking disable crtc On i915 this can lead to a spurious -EBUSY from step 3 on account of non-enabled planes getting the fake_commit in step 1 and we don't complete the fake_commit-> flip_done until drm_atomic_helper_commit_hw_done() which can happen a long time after the flip event was sent out. This will become somewhat easy to hit on SKL+ once we start to add all the planes for the crtc to every modeset commit for the purposes of forcing a watermark register programming [1]. To make the race a little less pronounced let's complete fake_commit->flip_done after drm_atomic_helper_wait_for_flip_done(). For the single crtc case this should make the race quite theoretical, assuming drm_atomic_helper_wait_for_flip_done() actually has to wait for the real commit flip_done. In case the real commit flip_done gets completed singificantly before drm_atomic_helper_wait_for_flip_done(), or we are dealing with multiple crtcs whose vblanks don't line up nicely the race still exists.

2018-11-23drm: rcar-du: Reject modes that fail CRTC timing requirementsLaurent Pinchart

2018-11-23drm: rcar-du: Fix external clock error checksLaurent Pinchart
The rcar-du driver supports probe deferral for external clocks, but implements it badly by checking the wrong pointer due to a bad copy and paste. Fix it. While at it, reject invalid clocks outright for DU channels that have a display PLL, as the external clock is mandatory in that case. This avoids a WARN_ON() at runtime.

If that transaction is not acked by sink, hardware will trigger this interruption. So let's disable PSR as it is a hint that there is problem with this sink. The removed FIXME was asking to manually train the link but we don't need to do that as by spec sink should do a short pulse when it is out of sync with source, we just need to make sure it is awaken and the SDP header with PSR inactive set it will trigger the short pulse with a error set in the link status. v3: added workarround to fix scheduled work starvation cause by to frequent PSR error interruption v4: only setting irq_aux_error as we don't care in clear it and not using dev_priv->irq_lock as consequence. v5: rebased: using edp_psr_shift() Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181121225441.18785-4-jose.souza@intel.com

2018-11-22drm/i915: Check PSR errors instead of retrain while PSR is enabledJosé Roberto de Souza
When a PSR error happens sink sets the PSR error register and also set the link status to a error status. So in the short pulse handling it was returning earlier and doing a full detection and attempting to retrain but it fails as PSR HW is in change of the main-link. Just call intel_psr_short_pulse() before intel_dp_needs_link_retrain() is not the right fix as intel_dp_needs_link_retrain() would return true and trigger a full detection while PSR HW is still in change of main-link. Check for PSR active is also not safe as it could be inactive due a frontbuffer invalidate and still doing the PSR exit sequence. v3: added comment in intel_dp_needs_link_retrain() Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181121225441.18785-2-jose.souza@intel.com
2018-11-22drm/i915: Avoid a full port detection in the first eDP short pulseJosé Roberto de Souza
Some eDP panels do not set a valid sink count value and even for the ones that sets is should always be one for eDP, that is why it is not cached in intel_edp_init_dpcd(). But intel_dp_short_pulse() compares the old count with the read one if there is a mistmatch a full port detection will be executed, what was happening in the first short pulse interruption of eDP panels that sets sink count. Instead of just skip the compasison for eDP panels, lets not read the sink count at all for eDP. v2: the previous version of this patch it was caching the sink count in intel_edp_init_dpcd() but I was pointed out by Ville a patch that handled a case of a eDP panel that do not set sink count and as sink count is not used to eDP certification was choosed to just not read it at all.

2018-11-21net: faraday: ftmac100: remove netif_running(netdev) check before disabling ↵Vincent Chen
interrupts In the original ftmac100_interrupt(), the interrupts are only disabled when the condition "netif_running(netdev)" is true. However, this condition causes kerenl hang in the following case. When the user requests to disable the network device, kernel will clear the bit __LINK_STATE_START from the dev->state and then call the driver's ndo_stop function. Network device interrupts are not blocked during this process. If an interrupt occurs between clearing __LINK_STATE_START and stopping network device, kernel cannot disable the interrupts due to the condition "netif_running(netdev)" in the ISR. Hence, kernel will hang due to the continuous interruption of the network device. In order to solve the above problem, the interrupts of the network device should always be disabled in the ISR without being restricted by the condition "netif_running(netdev)". [V2] Remove unnecessary curly braces. Signed-off-by: Vincent Chen <vincentc@andestech.com> Signed-off-by: David S. Miller <davem@davemloft.net>
