2019-10-18drm/i915: Restore full symmetry in i915_driver_modeset_probe/removeJanusz Krzysztofik2-4/+6
Commit 2d6f6f359fd8 ("drm/i915: add i915_driver_modeset_remove()") claimed removal of asymmetry in probe() and remove() calls, however, it didn't take care of calling intel_irq_uninstall() on driver remove. That doesn't hurt as long as we still call it from intel_modeset_driver_remove() but in order to have full symmetry we should call it again from i915_driver_modeset_remove(). Note that it's safe to call intel_irq_uninstall() twice thanks to commit b318b82455bd ("drm/i915: Nuke drm_driver irq vfuncs"). We may only want to mention the case we are adding in a related FIXME comment provided by that commit. While being at it, update the name of function mentioned as calling it out of sequence as that name has been changed meanwhile by commit 78dae1ac35dd ("drm/i915: Propagate "_remove" function name suffix down").

2019-10-18drm/edid: Fix HDMI VIC handlingVille Syrjälä1-16/+21
Extract drm_mode_hdmi_vic() to correctly calculate the final HDMI VIC for us. Currently this is being done a bit differently between the AVI and HDMI infoframes. Let's get both to agree on this. We need to allow the case where a mode is both 3D and has a HDMI VIC. Currently we'll just refuse to generate the HDMI infoframe when we really should be setting HDMI VIC to 0 and instead enabling 3D stereo signalling. If the sink doesn't even support the HDMI infoframe we should not be picking the HDMI VIC in favor of the CEA VIC, because then we'll end up not sending either VIC in the end.

Doug Berger says: ==================== net: bcmgenet: restore internal EPHY support I managed to get my hands on an old BCM97435SVMB board to do some testing with the latest kernel and uncovered a number of things that managed to get broken over the years (some by me ;). This commit set attempts to correct the errors I observed in my testing. The first commit applies to all internal PHYs to restore proper reporting of link status when a link comes up. The second commit restores the soft reset to the initialization of the older internal EPHYs used by 40nm Set-Top Box devices. The third corrects a bug I introduced when removing excessive soft resets by altering the initialization sequence in a way that keeps the GENETv3 MAC interface happy. Finally, I observed a number of issues when manually configuring the network interface of the older EPHYs that appear to be resolved by the fourth commit. ==================== Signed-off-by: David S.

2019-10-18net: bcmgenet: reset 40nm EPHY on energy detectDoug Berger1-1/+8
The EPHY integrated into the 40nm Set-Top Box devices can falsely detect energy when connected to a disabled peer interface. When the peer interface is enabled the EPHY will detect and report the link as active, but on occasion may get into a state where it is not able to exchange data with the connected GENET MAC. This issue has not been observed when the link parameters are auto-negotiated; however, it has been observed with a manually configured link. It has been empirically determined that issuing a soft reset to the EPHY when energy is detected prevents it from getting into this bad state.

2019-10-18net: bcmgenet: soft reset 40nm EPHYs before MAC initDoug Berger3-73/+69
It turns out that the "Workaround for putting the PHY in IDDQ mode" used by the internal EPHYs on 40nm Set-Top Box chips when powering down puts the interface to the GENET MAC in a state that can cause subsequent MAC resets to be incomplete. Rather than restore the forced soft reset when powering up internal PHYs, this commit moves the invocation of phy_init_hw earlier in the MAC initialization sequence to just before the MAC reset in the open and resume functions. This allows the interface to be stable and allows the MAC resets to be successful. The bcmgenet_mii_probe() function is split in two to accommodate this. The new function bcmgenet_mii_connect() handles the first half of the functionality before the MAC initialization, and the bcmgenet_mii_config() function is extended to provide the remaining PHY configuration following the MAC initialization.

2019-10-18drm/i915: Make hdcp2_msg_timeout.timeout u16Ville Syrjälä1-1/+1
All the timeout values fit in u16, so let's shrink the structure a bit. This ends up actually increasing the .text size a bit due to some changes in instructions (constant imul+small jmps replaced with mov+bigger jmpqs).

2019-10-18drm/i915: Remove hdcp2_hdmi_msg_timeout.timeout2Ville Syrjälä1-13/+15
The only reason for the timeout2 value in the array is the HDCP_2_2_AKE_SEND_HPRIME message. But that one still needs special casing inside the loop, and so just ends up making the code harder to read. Let's just remove this leaky timeout2 abstraction and special case that one command in a way that is easy to understand.

2019-10-18nvme-pci: Set the prp2 correctly when using more than 4k pageKevin Hao1-1/+2
In the current code, the nvme is using a fixed 4k PRP entry size, but if the kernel use a page size which is more than 4k, we should consider the situation that the bv_offset may be larger than the dev->ctrl.page_size. Otherwise we may miss setting the prp2 and then cause the command can't be executed correctly.

The 'realloc_pipes' bitmask is pointless. It is either: a) the set of pipes which are already part of the state, in which case adding them again is entirely redundant b) the set of all pipes which we then add to the state Also the fact that 'realloc_pipes' uses the crtc indexes is going to bite is at some point so best get rid of it quick.

The DP port/pipe goes wonky if we try to use timings with hdisplay==4096 on pre-HSW platforms. The link fails to train and the pipe may not signal vblank interrupts.
