From: Thierry Reding <treding@xxxxxxxxxx> This set of patches adds support for deferring FB helper setup, which is useful to obtain a sane configuration even when no outputs are available during probe. One example is HDMI, where fbdev will currently fallback to a 1024x786 resolution if no monitor is connected, and will then forever stay that way. With these patches, the FB helpers will take note that it doesn't make sense to setup fbdev yet and will defer until a monitor is connected, at which point the preferred mode will be selected. Thierry Changes in v4: - use fb_conn for variables of type struct drm_fb_helper_connector * for consistency - make top-level FB helper lock more robust - improve kerneldoc Changes in v3: - fix kerneldoc for top-level FB helper lock - drop some patches that no longer apply - add Tested-by from John Stultz - add cleanup patches Changes in v2: - now with locking Thierry Reding (11): drm/fb-helper: Cleanup checkpatch warnings drm/fb-helper: Reshuffle code for subsequent patches drm/fb-helper: Improve code readability drm/fb-helper: Push down modeset lock into FB helpers drm/fb-helper: Add top-level lock drm/fb-helper: Make top-level lock more robust drm/fb-helper: Support deferred setup drm/exynos: Remove custom FB helper deferred setup drm/hisilicon: Remove custom FB helper deferred setup drm/atmel-hlcdc: Remove unnecessary NULL check drm/rockchip: Remove unnecessary NULL check drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_dc.c | 3 +- drivers/gpu/drm/drm_fb_helper.c | 376 +++++++++++++++++------- drivers/gpu/drm/exynos/exynos_drm_drv.c | 6 +- drivers/gpu/drm/exynos/exynos_drm_fbdev.c | 23 -- drivers/gpu/drm/hisilicon/kirin/kirin_drm_drv.c | 21 +- drivers/gpu/drm/i915/intel_dp_mst.c | 3 - drivers/gpu/drm/radeon/radeon_dp_mst.c | 7 - drivers/gpu/drm/rockchip/rockchip_drm_fb.c | 4 +- include/drm/drm_fb_helper.h | 35 +++ 9 files changed, 316 insertions(+), 162 deletions(-) -- 2.12.0 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
