drm/fb-helper: Propagate errors from initial config failure

2015-01-21T13:57:03Z

Make drm_fb_helper_initial_config() return an int rather than a bool so that the error can be properly propagated. While at it, update drivers to propagate errors further rather than just ignore them. v2: - cirrus: No cleanup is required, the top-level cirrus_driver_load() will do it as part of cirrus_driver_unload() in its cleanup path.

bochs: fix bochsdrmfb mmap

2014-11-20T01:27:09Z

Remove the mapping offset from the bo backing the fbdev framebuffer. Wire up fbdev mmap function to map the backing bo using ttm_fbdev_mmap. With that patch in place mmap(/dev/fb0) works as expected. Signed-off-by: Gerd Hoffmann Signed-off-by: Dave Airlie

drm/ttm: Fix a few sparse warnings

2014-07-22T00:58:21Z

The final parameter to ttm_bo_reserve() is a pointer, therefore callers should use NULL instead of 0. Fixes a bunch of sparse warnings of this type: warning: Using plain integer as NULL pointer Signed-off-by: Thierry Reding Reviewed-by: Alex Deucher Signed-off-by: Dave Airlie

drm: Introduce drm_fb_helper_prepare()

2014-07-08T01:31:28Z

To implement hotplug detection in a race-free manner, drivers must call drm_kms_helper_poll_init() before hotplug events can be triggered. Such events can be triggered right after any of the encoders or connectors are initialized. At the same time, if the drm_fb_helper_hotplug_event() helper is used by a driver, then the poll helper requires some parts of the FB helper to be initialized to prevent a crash. At the same time, drm_fb_helper_init() requires information that is not necessarily available at such an early stage (number of CRTCs and connectors), so it cannot be used yet. Add a new helper, drm_fb_helper_prepare(), that initializes the bare minimum needed to allow drm_kms_helper_poll_init() to execute and any subsequent hotplug events to be processed properly.

There's no need for this to be modifiable. Make it const so that it can be put into the .rodata section. Reviewed-by: Daniel Vetter Signed-off-by: Thierry Reding Acked-by: Russell King Signed-off-by: Dave Airlie

drm/bochs: new driver

2013-12-23T01:02:39Z

DRM driver for (virtual) vga cards using the bochs dispi interface, such as the qemu standard vga (qemu -vga std). Don't bother supporting anything but 32bpp for now, even though the virtual hardware is able to do that. Known issue: mmap(/dev/fb0) doesn't work.
