2016-12-14mm: add locked parameter to get_user_pages_remote()Lorenzo Stoakes2-2/+2
Patch series "mm: unexport __get_user_pages_unlocked()". This patch series continues the cleanup of get_user_pages*() functions taking advantage of the fact we can now pass gup_flags as we please. It firstly adds an additional 'locked' parameter to get_user_pages_remote() to allow for its callers to utilise VM_FAULT_RETRY functionality. This is necessary as the invocation of __get_user_pages_unlocked() in process_vm_rw_single_vec() makes use of this and no other existing higher level function would allow it to do so. Secondly existing callers of __get_user_pages_unlocked() are replaced with the appropriate higher-level replacement - get_user_pages_unlocked() if the current task and memory descriptor are referenced, or get_user_pages_remote() if other task/memory descriptors are referenced (having acquiring mmap_sem.) This patch (of 2): Add a int *locked parameter to get_user_pages_remote() to allow VM_FAULT_RETRY faulting behaviour similar to get_user_pages_[un]locked(). Taking into account the previous adjustments to get_user_pages*() functions allowing for the passing of gup_flags, we are now in a position where __get_user_pages_unlocked() need only be exported for his ability to allow VM_FAULT_RETRY behaviour, this adjustment allows us to subsequently unexport __get_user_pages_unlocked() as well as allowing for future flexibility in the use of get_user_pages_remote().

2016-12-13drm/etnaviv: Use drm_dev_unref, not drm_put_devDaniel Vetter1-1/+1
drm_put_dev is the old midlayer-broken device cleanup function, but etnaviv has a proper unbind function which first unregisters and then drops the final reference. No functional change since drm_dev_unregister happens to be idempotent.

fsl is already fully demidlayered in the probe function, but for convenience stuck with drm_put_dev. Call the unregister/unref parts separately, to make sure this driver works correct.

2016-12-13drm/i915: Move all the DP compliance data to a separate structManasi Navare3-22/+26
This patch does not change anything functionally, just cleans up the DP compliance related variables and stores them all together in a separate struct intel_dp_compliance. There is another struct intel_dp_compliance_data to store all the test data. This makes it easy to reset the compliance variables through a memset instead of individual resetting. v2: * Removed functional changes for EDID (Jani Nikula) Reviewed-by: Jani Nikula <[email protected]> Signed-off-by: Manasi Navare <[email protected]> Cc: Jani Nikula <[email protected]> Cc: Daniel Vetter <[email protected]> Signed-off-by: Jani Nikula <[email protected]> Link: http://patchwork.freedesktop.org/patch/msgid/[email protected]
2016-12-13drm/i915: Find fallback link rate/lane countManasi Navare2-0/+40
If link training fails, then we need to fallback to lower link rate first and if link training fails at RBR, then fallback to lower lane count. This function finds the next lower link rate/lane count value after link training failure and limits the max link_rate and lane_count values to these fallback values. v7: * Remove unnecessary intializations and remove redundant call to intel_dp_common_rates (Jani Nikula) v6: * Cap the max link rate and lane count to the max values obtained during fallback link training (Daniel Vetter) v5: * Start the fallback at the lane count value passed not the max lane count (Jani Nikula) v4: * Remove the redundant variable link_train_failed v3: * Remove fallback_link_rate_index variable, just obtain that using the helper intel_dp_link_rate_index (Jani Nikula) v2: Squash the patch that returns the link rate index (Jani Nikula) Acked-by: Tony Cheng <[email protected]> Acked-by: Harry Wentland <[email protected]> Cc: Ville Syrjala <[email protected]> Cc: Jani Nikula <[email protected]> Cc: Daniel Vetter <[email protected]> Signed-off-by: Manasi Navare <[email protected]> Reviewed-by: Jani Nikula <[email protected]> Signed-off-by: Jani Nikula <[email protected]> Link: http://patchwork.freedesktop.org/patch/msgid/[email protected]
2016-12-13drm/i915: Compute sink's max lane count/link BW at HotplugManasi Navare2-2/+12
Sink's capabilities are advertised through DPCD registers and get updated only on hotplug. So they should be computed only once in the long pulse handler and saved off in intel_dp structure for the use later. For this reason two new fields max_sink_lane_count and max_sink_link_bw are added to intel_dp structure. This also simplifies the fallback link rate/lane count logic to handle link training failure. In that case, the max_sink_link_bw and max_sink_lane_count can be reccomputed to match the fallback values lowering the sink capabilities due to link train failure.

Request the GPIO by index through the consumer API. For now, use a quick hack to store the already requested ones, simply because I have no idea whether this actually works or not, and I have no way to test it. v2 by Mika: switch *NULL* to *"panel"* when requesting gpio for MIPI/DSI panel.

2016-12-13drm/hisilicon: Don't set drm_device->platformdevDaniel Vetter3-15/+8
It's deprecated and only should be used by drivers which still use drm_platform_init, not by anyone else. And indeed it's entirely unused and can be nuked. This required a bit more fudging, but I guess kirin_dc_ops really wants to operate on the platform_device, not something else. Also bonus points for implementing abstraction, and then storing the vfunc in a global variable. v2: Don't break the build soooo badly :( Note that the cleanup function is a bit confused: ade_data was never set as drvdata, and calling drm_crtc_cleanup directly is a bug - this is called indirectly through drm_mode_config_cleanup, which calls into crtc->destroy, which already has the call to drm_crtc_cleanup. Which means we can just nuke it. Note this is the 2nd attempt after the first one failed and had to be reverted again in commit 9cd2e854d61ccfa51686f3ed7b0c917708fc641f Author: Daniel Vetter <[email protected]> Date: Wed Aug 17 13:59:40 2016 +0200 Revert "drm/hisilicon: Don't set drm_device->platformdev" Cc: Xinliang Liu <[email protected]> Cc: Xinwei Kong <[email protected]> Cc: Archit Taneja <[email protected]> Cc: Sean Paul <[email protected]> Reviewed-by: Sean Paul <[email protected]> Signed-off-by: Daniel Vetter <[email protected]> Link: http://patchwork.freedesktop.org/patch/msgid/[email protected]

2016-12-13drm: Enforce BKL-less ioctls for modern driversDaniel Vetter1-3/+2
With the last round of changes all ioctls called by modern drivers now have their own locking. Everything else is only allowed for legacy drivers and hence the lack of locking doesn't matter. One exception is nouveau, due to the DRIVER_KMS_LEGACY_CONTEXT flag. But that only works its magic on the context and bufs ioctls. And drm_bufs.c is protected with dev->struct_mutex, and drm_context.c by the same and dev->ctxlist_mutex. That should be all safe, and we can finally mandata drm-bkl-less ioctls for everyone!
