2014-08-06drm/panel: add .prepare() and .unprepare() functionsAjay Kumar1-0/+50
Panels often require an initialization sequence that consists of three steps: a) powering up the panel, b) starting transmission of video data and c) enabling the panel (e.g. turn on backlight). This is usually necessary to avoid visual glitches at the beginning of video data transmission. Similarly, the shutdown sequence is typically done in three steps as well: a) disable the panel (e.g. turn off backlight), b) cease video data transmission and c) power down the panel. Currently drivers can only implement .enable() and .disable() functions, which is not enough to implement the above sequences. This commit adds a second pair of functions, .prepare() and .unprepare() to allow more fine-grained control over when the above steps are performed.

2014-08-06drm/panel: simple: Remove simple-panel compatibleThierry Reding1-2/+0
simple-panel is not a valid panel model, so there is no data (video timings, etc.) associated with it. Therefore drivers can't do anything useful with it, so it should not appear in the table of OF matches. Device trees will always need to specify the exact model of the panel.

We need to take the connection mutex around the link status check for non-MST case, but also around the MST link training on short HPDs.

2014-08-05drm: make sysfs device always available for minorsDavid Herrmann3-61/+54
For each minor we allocate a sysfs device as minor->kdev. Currently, this is allocated and registered in drm_minor_register(). This makes it impossible to add sysfs-attributes to the device before it is registered. Therefore, they are not added atomically, nor can we move device_add() *after* ->load() is called. This patch makes minor->kdev available early, but only adds the device during minor-registration. Note that the registration is still called before ->load() as debugfs needs to be split, too. This will be fixed in follow-ups. Reviewed-by: Daniel Vetter <[email protected]> Reviewed-by: Alex Deucher <[email protected]> Signed-off-by: David Herrmann <[email protected]>
2014-08-05drm: make minor->index available earlyDavid Herrmann1-38/+46
Instead of allocating the minor-index during registration, we now do this during allocation. This way, debug-messages between minor-allocation and minor-registration will now use the correct minor instead of 0. Same is done for unregistration vs. free, so debug-messages between device-shutdown and device-destruction show proper indices. Even though minor-indices are allocated early, we don't enable minor lookup early. Instead, we keep the entry set to NULL and replace it during registration / unregistration. This way, the index is allocated but lookup only works if registered.

2014-08-05drm: move module initialization to drm_stub.cDavid Herrmann4-104/+115
Most of the new DRM management functions are nowadays in drm_stub.c. By moving the core module initialization to drm_stub.c we can make several global variables static and keep the stub-open helper local. The core files now look like this: drm_stub.c: Core management drm_drv.c: Ioctl dispatcher drm_ioctl.c: Actual ioctl backends drm_fops.c: Char-dev file-operations A follow-up patch will move what is left from drm_drv.c into drm_ioctl.c.

2014-08-05drm: don't de-authenticate clients on master-closeDavid Herrmann2-12/+2
If an active DRM-Master closes its device, we deauthenticate all clients on that master. However, if an inactive DRM-Master closes its device, we do nothing. This is quite inconsistent and breaks several scenarios: 1) If this was used as security mechanism, it fails horribly if a master closes a device while VT switched away. Furthermore, none of the few drivers using ->master_*() callbacks seems to require it, anyway. 2) If you spawn weston (or any other non-UMS compositor) in background while another compositor is active, both will get assigned to the same "drm_master" object. If the foreground compositor now exits, all clients of both the foreground AND background compositor will be de-authenticated leading to unexpected behavior. Stop this non-sense and keep clients authenticated. We don't do this when dropping DRM-Master (i.e., switching VTs) so don't do it on active-close either!

2014-08-05drm: drop redundant drm_file->is_masterDavid Herrmann9-20/+27
The drm_file->is_master field is redundant as it's equivalent to: drm_file->master && drm_file->master == drm_file->minor->master 1) "=>" Whenever we set drm_file->is_master, we also set: drm_file->minor->master = drm_file->master; Whenever we clear drm_file->is_master, we also call: drm_master_put(&drm_file->minor->master); which implicitly clears it to NULL. 2) "<=" minor->master cannot be set if it is non-NULL. Therefore, it stays as is unless a file drops it. If minor->master is NULL, it is only set by places that also adjust drm_file->is_master. Therefore, we can safely drop is_master and replace it by an inline helper that matches: drm_file->master && drm_file->master == drm_file->minor->master Reviewed-by: Alex Deucher <[email protected]> Reviewed-by: Daniel Vetter <[email protected]> Signed-off-by: David Herrmann <[email protected]>
2014-08-05drm: extract legacy ctxbitmap flushingDavid Herrmann3-19/+32
The ctxbitmap code is only used by legacy drivers so lets try to keep it as separated as possible. Furthermore, the locking is non-obvious and kinda weird with ctxlist_mutex *and* struct_mutex. Keeping all ctxbitmap access in one file is much easier to review and makes drm_release() more readable.

2014-08-05drm/radeon: Use pflip irqs for pageflip completion if possible. (v2)Mario Kleiner7-5/+27
Skip the "manual" pageflip completion checks via polling and guessing in the vblank handler radeon_crtc_handle_vblank() on asics which are known to reliably support hw pageflip completion irqs. Those pflip irqs are a more reliable and race-free method of handling pageflip completion detection, whereas the "classic" polling method has some small races in combination with dpm on, and with the reworked pageflip implementation since Linux 3.16. On old asics without pflip irqs, the classic method is used. On asics with known good pflip irqs, only pflip irqs are used by default, but a new module parameter "use_pflipirqs" allows to override this in case we encounter asics in the wild with unreliable or faulty pflip irqs. A module parameter of 0 allows to use the classic method only in such a case. A parameter of 1 allows to use both classic method and pflip irqs as additional band-aid to avoid some small races which could happen with the classic method alone. The setting 1 gives Linux 3.16 behaviour. Hw pflip irqs are available since R600. Tested on DCE-4, AMD Cedar - FirePro 2270. v2: agd5f: only enable pflip interrupts on DCE4+ as they are not reliable on older asics.
