* drm: Extract drm_mode_object.[hc]Daniel Vetter2016-08-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | Just for the struct drm_mode_object base class. The header file was already partially extracted to help untangle the include loops. v2: - Also move the generic get/set property ioctls. At first this seemed like a bad idea since it requires making drm_mode_crtc_set_obj_prop non-static. But eventually that will get split away too (like the connector version already is) for both crtc and planes. Hence I reconsidered. - drm_mode_object.[hc] instead of drm_modeset.[hc], which requires renaming the drm_modeset.h header I already started building up. This is more consistent (matches the name of the main structure), and I want to be able to use drm_modeset.[hc] for the basic modeset init/cleanup functionality like drm_mode_config_init.

* drm: Extract drm_connector.[hc]Daniel Vetter2016-08-161-15/+1
| | | | | | | | | | | | | | | | | | Pulls in quite a lot of connector related structures (cmdline mode, force/status enums, display info), but I think that all makes perfect sense. Also had to move a few more core kms object stuff into drm_modeset.h. And as a first cleanup remove the kerneldoc for the 2 connector IOCTL - DRM core docs are aimed at drivers, no point documenting internal in excruciating detail. v2: And also pull in all the connector property code.

* drm: Extract drm_framebuffer.[hc]Daniel Vetter2016-08-161-0/+2
| | | | | | | | | | | | | | | | | | Also start with drm_modeset.h with the core bits, since we need to untangle this mess somehow. That allows us to move the drm_modes.h include to the right spot, except for the temporary connector status enum. That will get fixed as soon as drm_connector.h exists. v2: Rebase. v3: Move drm_crtc_force_disable_all back again, that wasn't meant to be moved (Sean). v4: Rebase.

* drm/edid: Make the detailed timing CEA/HDMI mode fixup accept up to 5kHz ↵Ville Syrjälä2015-12-011-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | clock difference Rather than using drm_match_cea_mode() to see if the EDID detailed timings are supposed to represent one of the CEA/HDMI modes, add a special version of that function that takes in an explicit clock tolerance value (in kHz). When looking at the detailed timings specify the tolerance as 5kHz due to the 10kHz clock resolution limit inherent in detailed timings. drm_match_cea_mode() uses the normal KHZ2PICOS() matching of clocks, which only allows smaller errors for lower clocks (eg. for 25200 it won't allow any error) and a bigger error for higher clocks (eg. for 297000 it actually matches 296913-297000). So it doesn't really match what we want for the fixup. Using the explicit +-5kHz is much better for this use case. Not sure if we should change the normal mode matching to also use something else besides KHZ2PICOS() since it allows a different proportion of error depending on the clock. I believe VESA CVT allows a maximum deviation of .5%, so using that for normal mode matching might be a good idea?

The checks include: - clock,hdisplay,vdisplay are non zero - sync pulse fits within the blanking period - htotal,vtotal are big enough I have not checked all the drivers to see if the modes the generate might violate these constraints. I'm hoping not, because that would mean either abandoning the idea of doing this from the core code, or fixing the drivers. I'm not entirely sure about limiting the sync pulse to the blanking period. Intel hardware doesn't support such things, but some other hardware might. However at least HDMI doesn't allow having sync pulse edges within the active period, so I'm thinking the check is probably OK to have in the common code.
