The functions instruct the client to poll for changed output or restore the display. The DRM core calls both, the old callbacks and the new client helpers, from the same places. The new functions perform the same operation as before, so there's no change in functionality.

Instead initialize the fbdev client by a single call to i915_fbdev_setup() after i915 has registered its DRM device. Just like similar code in other drivers, i915 fbdev emulation now acts as a regular DRM client. The fbdev client setup consists of the initial preparation and the hot-plugging of the display. The latter creates the fbdev device and sets up the fbdev framebuffer. The setup performs display hot-plugging once. If no display can be detected, DRM probe helpers re-run the detection on each hotplug event. A call to drm_dev_unregister() releases the client automatically. No further action is required within i915. If the fbdev framebuffer has been fully set up, struct fb_ops.fb_destroy implements the release. For partially initialized emulation, the fbdev client reverts the initial setup. v2: * let drm_client_register() handle initial hotplug * fix driver name in error message (Jani) * fix non-fbdev build (kernel test robot) Signed-off-by: Thomas Zimmermann --- drivers/gpu/drm/i915/display/intel_display.c | 1 - .../drm/i915/display/intel_display_driver.c | 18 -- drivers/gpu/drm/i915/display/intel_fbdev.c | 182 ++++++++---------- drivers/gpu/drm/i915/display/intel_fbdev.h | 20 +- drivers/gpu/drm/i915/i915_driver.c | 2 + 5 files changed, 84 insertions(+), 139 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_display.c b/drivers/gpu/drm/i915/display/intel_display.c index 83e1bc858b9fb..64578f991f41d 100644 --- a/drivers/gpu/drm/i915/display/intel_display.c +++ b/drivers/gpu/drm/i915/display/intel_display.c @@ -81,7 +81,6 @@ #include "intel_dvo.h" #include "intel_fb.h" #include "intel_fbc.h" -#include "intel_fbdev.h" #include "intel_fdi.h" #include "intel_fifo_underrun.h" #include "intel_frontbuffer.h" diff --git a/drivers/gpu/drm/i915/display/intel_display_driver.c b/drivers/gpu/drm/i915/display/intel_display_driver.c index 0650c0ed30a0c..7f0d6dbc47cae 100644 --- a/drivers/gpu/drm/i915/display/intel_display_driver.c +++ b/drivers/gpu/drm/i915/display/intel_display_driver.c @@ -364,10 +364,6 @@ int intel_display_driver_probe(struct drm_i915_private *i915) intel_overlay_setup(i915); - ret = intel_fbdev_init(&i915->drm); - if (ret) - return ret; - /* Only enable hotplug handling once the fbdev is fully set up. */ intel_hpd_init(i915); intel_hpd_poll_disable(i915); @@ -390,16 +386,6 @@ void intel_display_driver_register(struct drm_i915_private *i915) intel_display_debugfs_register(i915); - /* - * Some ports require correctly set-up hpd registers for - * detection to work properly (leading to ghost connected - * connector status), e.g. VGA on gm45.
