drm: mark drm_context support as legacy

2014-08-05T17:38:12+00:00

This renames all drm-context helpers to drm_legacy_*() and moves the internal definitions into the new drm_legacy.h header. This header is local to DRM-core and drivers shouldn't access it. Reviewed-by: Daniel Vetter Signed-off-by: David Herrmann

drm: make sysfs device always available for minors

2014-08-05T14:08:21+00:00

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 Reviewed-by: Alex Deucher Signed-off-by: David Herrmann

drm: make minor->index available early

2014-08-05T14:08:17+00:00

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. Reviewed-by: Daniel Vetter Reviewed-by: Alex Deucher Signed-off-by: David Herrmann

drm: move module initialization to drm_stub.c

2014-08-05T14:07:59+00:00

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.

drm: drop redundant drm_file->is_master

2014-08-05T14:07:50+00:00

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 Reviewed-by: Daniel Vetter Signed-off-by: David Herrmann

drm: Remove command line guard for universal planes

2014-07-08T01:56:21+00:00

Universal planes are ready to leave 'experimental' state so drop the kernel command line parameter that we've been hiding them behind. Userspace clients that wish to receive universal planes will still need to opt-in by setting the appropriate capability bit, so this should have no impact on existing userspace.

drm: enable render-nodes by default

drm: Don't export internal module variables

2014-06-18T11:50:16+00:00

Drivers really have no business touching these. Noticed because exynose _did_ touch the vblank off delay, which could potentially affect other drivers. drm_debug is an exception since it's used in macros and inline functions. Note that this reduces the timeout on exynos from 50s to 5s. Apparently this was done to paper over a vblank get/put race in exynos, but really should be fixed properly somewhere else. Spotted by David. v2: Drop bonghits changes. Note to self: Don't submit patches before first coffee. Cc: Inki Dae Reviewed-by: David Herrmann Signed-off-by: Daniel Vetter
