2016-02-19drm/atomic: Allow for holes in connector state, v2.Maarten Lankhorst
Because we record connector_mask using 1 << drm_connector_index now the connector_mask should stay the same even when other connectors are removed. This was not the case with MST, in that case when removing a connector all other connectors may change their index. This is fixed by waiting until the first get_connector_state to allocate connector_state, and force reallocation when state is too small. As a side effect connector arrays no longer have to be preallocated, and can be allocated on first use which means a less allocations in the page flip only path. Changes since v1: - Whitespace. (Ville) - Call ida_remove when destroying the connector. (Ville) - u32 alloc -> int. (Ville) Fixes: 14de6c44d149 ("drm/atomic: Remove drm_atomic_connectors_for_crtc.")

2016-02-12drm/dp: Add a drm_aux-dev module for reading/writing dpcd registers.Rafael Antognolli
This module is heavily based on i2c-dev. Once loaded, it provides one dev node per DP AUX channel, named drm_dp_auxN, where N is an integer. It's possible to know which connector owns this aux channel by looking at the respective sysfs /sys/class/drm_aux_dev/drm_dp_auxN/connector, if the connector device pointer was correctly set in the aux helper struct. Two main operations are provided on the registers read and write. The address of the register to be read or written is given using lseek. The seek position is updated upon read or write. v2: - lseek is used to select the register to read/write - read/write are used instead of ioctl - no blocking_notifier is used, just a direct callback v3: - use drm_dp_aux_dev prefix for public functions - chardev is named drm_dp_auxN - read/write don't allocate a buffer anymore, and transfer up to 16 bytes a time - remove notifier list from the implementation - option on menuconfig is now a boolean - add inline stub functions to avoid breakage when this option is disabled v4: - fix build system changes - actually disable this module when not selected. v5: - Use kref to avoid device closing while still in use - Don't use list, use an idr for storing aux_dev - Remove "connector" attribute - set aux.dev to the connector drm_connector device, instead of drm_device v6: - Use atomic_t for usage count - Use a mutex instead of spinlock for idr lock - Destroy chardev immediately on unregister - other minor suggestions from Ville v7: - style fixes - error handling fixes v8: - more error handling fixes v9: - remove module_init and module_exit, and add drm_dp_aux_dev_init/exit to drm_kms_helper_init/exit.

2016-02-09drm/edid: Switch DDC when reading the EDIDLukas Wunner
Originally by Seth Forshee <seth.forshee@canonical.com>, 2012-10-04: Some dual graphics machines support muxing the DDC separately from the display, so make use of this functionality when reading the EDID on the inactive GPU. Also serialize drm_get_edid() with a mutex to avoid races on the DDC mux state. Modified by Dave Airlie <airlied@gmail.com>, 2012-12-22: I can't figure out why I didn't like this, but I rewrote this [...] to lock/unlock the ddc lines [...]. I think I'd prefer something like that otherwise the interface got really ugly.

There's really no reason to not do so, instead of replicating this for every use-case and every driver. Now we can't just nuke the events, since that would still mean that all drm_event users would need to know when that has happened, since calling e.g. drm_send_event isn't allowed any more.

Boris dug out Thierry's drm-trivial branch and resubmitted everything since that branch didn't really work out. On top of that Nicolas' changes to drm_dev_set_unique - this might conflict with new driver pulls (I double checked and current drm-next should be fine), so please beware.

2015-12-15drm: make drm_dev_set_unique() not use a format stringNicolas Iooss
drm_dev_set_unique() uses a format string to define the unique name of a device. This feature is not used as currently all the calls to this function either use "%s" as a format string or directly use dev_name(). Even though this second kind of call does not introduce security problems, because there cannot be "%" characters in dev_name() results, gcc issues a warning when building with -Wformat-security flag ("warning: format string is not a string literal (potentially insecure)"). This warning is useful to find real bugs like the one fixed by commit 3958b79266b1 ("configfs: fix kernel infoleak through user-controlled format string"). False positives which do not bring an extra value make the work of finding real bugs harder. Therefore remove the format-string feature from drm_dev_set_unique().

Add get_eld audio component for i915/HD-audio Currently, the HDMI/DP audio status and ELD are notified and obtained via the hardware-level communication over HD-audio unsolicited event and verbs although the graphics driver holds the exactly same information. As we already have a notification via audio component, this is another step forward; namely, the audio driver may fetch directly the audio status and ELD via the new component op.
