[PATCH] drm: Fix DRM_FORCE_ON_DIGITAL use
by Peter Hurley 04 Nov '14

04 Nov '14

A connector may be forced on from the command line via video= command line setting. The digital output of dual-mode connectors can also be specifically selected and forced on; eg., 'video=DVI-I-2:D'. However, in this case, the connector->status will be mistakenly set to connector_status_disconnected, and the connector will not be mode set. Fix the connector->status when connector->force is DRM_FORCE_ON_DIGITAL.

[PATCH v2 0/5] video: describe data bus formats
by Boris Brezillon 03 Nov '14

03 Nov '14

Hello, This patch series is a proposal to describe the different data formats used by HW components to connect with each other. This is just a copy of the existing V4L2_MBUS_FMT defintions with a neutral name so that it can be used by V4L2 and DRM/KMS subsystem. This series also makes use of this video_bus_format enum in the DRM/KMS subsystem to define the data fomats supported on the connector <-> device link. Best Regards, Boris Changes since v1: - define an enum and use a macro for v4l2 bus formats definitions - rename nformats into num_formats - declare num_formats as an unsigned int Boris BREZILLON (3): drm: add bus_formats and nbus_formats fields to drm_display_info drm: panel: simple-panel: add support for bus_format retrieval drm: panel: simple-panel: add bus format information for foxlink panel Boris Brezillon (2): video: move mediabus format definition to a more standard place video: add RGB444_1X12 and RGB565_1X16 bus formats drivers/gpu/drm/drm_crtc.c | 31 ++++++ drivers/gpu/drm/panel/panel-simple.c | 6 ++ include/drm/drm_crtc.h | 8 ++ include/uapi/linux/Kbuild | 1 + include/uapi/linux/v4l2-mediabus.h | 185 +++++++++++++++------------------- include/uapi/linux/video-bus-format.h | 129 ++++++++++++++++++++++++ 6 files changed, 256 insertions(+), 104 deletions(-) create mode 100644 include/uapi/linux/video-bus-format.h -- 1.9.1

Hi! Details in https://bugzilla.redhat.com/show_bug.cgi?id=1155825 Can whoever broke the driver please make an effort to fix it up? Daniel, You've been named as a suspect. I'm not sure if that is true. Thanks, Thomas

Hi Dave, drm-intel-next-2014-10-24: - suspend/resume/freeze/thaw unification from Imre - wa list improvements from Mika&Arun - display pll precomputation from Ander Conselvan prep work - more kerneldoc for the interrupt code - 180 rotation for cursors (Ville&Sonika) - ULT/ULX feature check macros cleaned up thanks to Damien - piles and piles of fixes all over, bug team seems to work! Aside: the tag log summary is a bit bogus - I've only merged Ander's prep work with this, the actuall dpll precomputation patches will be in the next round. So please copypaste the above fixed shortlog into the merge commit.

Hi Dave, This pull-request includes some bug fixes and code cleanups. Especially, this fixes the bind failure issue occurred when it tries to re-bind Exynos drm driver after unbound, and the modetest failure issue incurred by not having a pair to vblank on and off requests.
