2014-03-19drm/i915: Rename similar plane functions to avoid confusionMatt Roper
The name 'update_plane' was used both for the primary plane functions in intel_display.c and the sprite/overlay functions in intel_sprite.c. Rename the primary plane functions to 'update_primary_plane' to avoid confusion. On a similar note, intel_display.c already had a function called intel_disable_primary_plane() that programs the hardware to disable a pipe's primary plane. When we hook up primary planes through the DRM plane interface, one of the natural handler names will be intel_primary_plane_disable(), which is very similar. To avoid confusion, rename the existing intel_disable_primary_plane() to intel_disable_primary_hw_plane() to make the two names a little more distinct.

2014-03-19drm/i915: Do not dereference pointers from ring buffer in evict eventSteven Rostedt
The TP_printk() should never dereference any pointers, because the ring buffer can be read at some unknown time in the future. If a device no longer exists, it can cause a kernel oops. This also makes this event useless when saving the ring buffer in userspaces tools such as perf and trace-cmd. The i915_gem_evict_vm dereferences the vm pointer which may also not exist when the ring buffer is read sometime in the future.

This is a small follow-up fix to the series of eDP VDD back and forth we've had recently.

2014-03-18drm/i915: Fix up the forcewake timer initializationDaniel Vetter
This is a regression introduced in commit 0294ae7b44bba7ab0d4cef9a8736287f38bdb4fd Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu Mar 13 12:00:29 2014 +0000 drm/i915: Consolidate forcewake resetting to a single function The reordered setup sequence ended up calling del_timer_sync before the timer was set up correctly, resulting in endless hilarity when loading the driver. Compared to Ben's patch (which moved around the setup_timer call to sanitize_early) this moves the sanitize_early call around in the driver load call. This way we avoid calling setup_timer again in the resume code (where we also call sanitize_early).

2014-03-18drm/dp: let drivers specify the name of the I2C-over-AUX adapterJani Nikula
Let the drivers specify the name of the I2C-over-AUX adapter to maintain backwards compatibility in the sysfs when converting to the new I2C-over-AUX helper infrastructure. The i915 driver currently uses DPDDC-A to DPDDC-D as names for the DP i2c adapters. These names show up in the i2c sysfs name attribute. We'd like to be able to maintain that when switching over to the new helpers. Due to i2c device and connector cleanup ordering issues we also recently made the drm device (instead of connector) the parent of the i2c adapters: commit 80f65de3c9b8101c1613fa82df500ba6a099a11c Author: Imre Deak <imre.deak@intel.com> Date: Tue Feb 11 17:12:49 2014 +0200 drm/i915: dp: fix order of dp aux i2c device cleanup With the name picked up from the adapter parent using dev_name(), it would be the same for all i2c adapters with the current I2C-over-AUX helpers.

2014-03-17drm/fb-helper: Do the 'max_conn_count' zero checkXiubo Li
Since we cannot make sure the 'max_conn_count' will always be none zero from the users, and then if max_conn_count equals to zero, the kcalloc() will return ZERO_SIZE_PTR, which equals to ((void *)16). So this patch fix this with just doing the 'max_conn_count' zero check in the front of drm_fb_helper_init().

We allocate memory in drm_display_mode_from_vic_index() and use it without checking the pointer is valid. Fix that. Signed-off-by: Damien Lespiau <damien.lespiau@intel.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2014-03-17drm/fb-helper: Use drm_fb_helper_restore_fbdev_mode() in drm_fb_helper_set_par()Ville Syrjälä
Use drm_fb_helper_restore_fbdev_mode() in drm_fb_helper_set_par() to make sure extra planes get disabled whenever fbcon takes over. Otherwise the code in drm_fb_helper_set_par() was already doing the exact same thing as drm_fb_helper_restore_fbdev_mode(), so this doesn't change the behaviour in any other way.

2014-03-17Merge branch 'drm-minor' of git://people.freedesktop.org/~dvdhrm/linux into ↵Dave Airlie
drm-next This series contains several cleanups for the DRM-minor handling. All but the last one reviewed by Daniel and tested by Thierry. Initially, the series included patches to convert minor-handling to a common base-ID, but have been NACKed by Daniel so I dropped them and only included the main part in the last patch. With this in place, drm_global_mutex is no longer needed for minor-handling (but still for device unregistration..). There are some pending patches that try to remove the global mutex entirely, but they need some more reviews and thus are not included. * 'drm-minor' of git://people.freedesktop.org/~dvdhrm/linux: drm: make minors independent of global lock drm: inline drm_minor_get_id() drm: coding-style fixes in minor handling drm: remove redundant minor->device field drm: remove unneeded #ifdef CONFIG_DEBUGFS drm: rename drm_unplug/get_minor() to drm_minor_register/unregister() drm: move drm_put_minor() to drm_minor_free() drm: allocate minors early drm: add minor-lookup/release helpers drm: provide device-refcount drm: turn DRM_MINOR_* into enum drm: remove unused DRM_MINOR_UNASSIGNED drm: skip redundant minor-lookup in open path drm: group dev-lifetime related members
