drm: Allow userspace to ask for universal plane list (v2)

2014-04-02T00:18:29+00:00

Userspace clients which wish to receive all DRM planes (primary and cursor planes in addition to the traditional overlay planes) may set the DRM_CLIENT_CAP_UNIVERSAL_PLANES capability. v2: Hide behind drm.universal_planes module option [suggested by Daniel Vetter] Signed-off-by: Matt Roper Reviewed-by: Rob Clark

drm: Add a function to get the ioctl flags

drm: Protect the master management with a drm_device::master_mutex v3

2014-03-28T13:19:02+00:00

The master management was previously protected by the drm_device::struct_mutex. In order to avoid locking order violations in a reworked dropped master security check in the vmwgfx driver, break it out into a separate master_mutex. Locking order is master_mutex -> struct_mutex. Also remove drm_master::blocked since it's not used. v2: Add an inline comment about what drm_device::master_mutex is protecting. v3: Remove unneeded struct_mutex locks. Fix error returns in drm_setmaster_ioctl(). Signed-off-by: Thomas Hellstrom Reviewed-by: Brian Paul Reviewed-by: David Herrmann Acked-by: Daniel Vetter

drm: Remove the minor master list

It doesn't appear to be used anywhere. Signed-off-by: Thomas Hellstrom Reviewed-by: David Herrmann

drm: Improve on minor type helpers v3

2014-03-28T13:19:01+00:00

Add a drm_is_legacy() helper, constify argument to drm_is_render_client(), and use / change helpers where appropriate. v2: s/drm_is_legacy/drm_is_legacy_client/ and adapt to new code context. v3: s/legacy_client/primary_client/ Signed-off-by: Thomas Hellstrom Reviewed-by: Brian Paul

drm: Make control nodes master-less v3

2014-03-28T13:19:01+00:00

Like for render-nodes, there is no point in maintaining the master concept for control nodes, so set the struct drm_file::master pointer to NULL. At the same time, make sure DRM_MASTER | DRM_CONTROL_ALLOW ioctls are always allowed when called through the control node. Previously the caller also needed to be master. v2: Adapt to refactoring of ioctl permission check. v3: Formatting of logical expression. Use drm_is_control_client() instead of drm_is_control().

drm: Remove the prefix argument of drm_ut_debug_printk()

2014-03-28T02:57:45+00:00

This is always DRM_NAME, so we can just make it part of the format string instead of asking prink to do it for us. Signed-off-by: Damien Lespiau Signed-off-by: Dave Airlie

drm: Pull the test on drm_debug in the logging macros

2014-03-28T02:57:36+00:00

In the logging code, we are currently checking is we need to output in drm_ut_debug_printk(). This is too late. The problem is that when we write something like: DRM_DEBUG_DRIVER("ELD on [CONNECTOR:%d:%s], [ENCODER:%d:%s]\n", connector->base.id, drm_get_connector_name(connector), connector->encoder->base.id, drm_get_encoder_name(connector->encoder)); We start by evaluating the arguments (so call drm_get_connector_name() and drm_get_connector_name()) before ending up in drm_ut_debug_printk() which will then does nothing. This means we execute a lot of instructions (drm_get_connector_name(), in turn, calls snprintf() for example) to happily discard them in the normal case, drm.debug=0. So, let's put the test on drm_debug earlier, in the macros themselves. Sprinkle an unlikely() as well for good measure. Signed-off-by: Damien Lespiau Signed-off-by: Dave Airlie

drm: Remove the unused (and unusable) DRM_LOG_MODE()

2014-03-28T02:57:01+00:00

This macro was trying to use the non existing DRM_UT_MODE debug category and looks like it should be covered by DRM_LOG_KMS(). Signed-off-by: Damien Lespiau Signed-off-by: Dave Airlie
