drm/kms-helpers: Extract drm_modeset_helper.[hc]

2016-08-16T14:10:19Z

While reviewing docs I spotted that we have a few functions that really just don't fit into their containing helper library section. Extract them and shovel them all into a new library for random one-off aux stuff. v2: Remove wrongly added files for real.

drm: drm_helper_crtc_enable_color_mgmt() => drm_crtc_enable_color_mgmt()

2016-06-07T14:10:49Z

Add drm_crtc_enable_color_mgmt(), remove drm_helper_crtc_enable_color_mgmt() and update drm/i915-driver (the only user of the old function). The new function is more flexible. It allows driver to enable only the features it has without forcing to enable all three color management properties: degamma lut, csc matrix (ctm), and gamma lut.

drm: introduce pipe color correction properties

2016-03-08T12:57:32Z

Patch based on a previous series by Shashank Sharma. This introduces optional properties to enable color correction at the pipe level. It relies on 3 transformations applied to every pixels displayed. First a lookup into a degamma table, then a multiplication of the rgb components by a 3x3 matrix and finally another lookup into a gamma table. The following properties can be added to a pipe : - DEGAMMA_LUT : blob containing degamma LUT - DEGAMMA_LUT_SIZE : number of elements in DEGAMMA_LUT - CTM : transformation matrix applied after the degamma LUT - GAMMA_LUT : blob containing gamma LUT - GAMMA_LUT_SIZE : number of elements in GAMMA_LUT DEGAMMA_LUT_SIZE and GAMMA_LUT_SIZE are read only properties, set by the driver to tell userspace applications what sizes should be the lookup tables in DEGAMMA_LUT and GAMMA_LUT. A helper is also provided so legacy gamma correction is redirected through these new properties. v2: Register LUT size properties as range v3: Fix round in drm_color_lut_get_value() helper More docs on how degamma/gamma properties are used v4: Update contributors v5: Rename CTM_MATRIX property to CTM (Doh!)

drm: Drop drm_helper_probe_single_connector_modes_nomerge()

2015-12-11T08:32:53Z

Now that the mode type bit merge logic is fixed to only merge between new probed modes, hopefully we can eliminat the special case for qxl and virtio. That is make the merge the mode type bits from all matching new probed modes, just like every other driver. qxl and virtio got excluded from the merging in commit 3fbd6439e463 ("drm: copy mode type in drm_mode_connector_list_update()") commit abce1ec9b08a ("Revert "drm: copy mode type in drm_mode_connector_list_update()"") commit b87577b7c768 ("drm: try harder to avoid regression when merging mode bits") Cc: Marc-André Lureau Cc: Dave Airlie Cc: Daniel Vetter Cc: Adam Jackson Signed-off-by: Ville Syrjälä [danvet: Resolve conflicts with doc updates.] Signed-off-by: Daniel Vetter

drm: Reorganize helper vtables and their docs

2015-12-08T15:07:52Z

Currently we have 4 helper libraries (probe, crtc, plane & atomic) that all use the same helper vtables. And that's by necessity since we don't want to litter the core structs with one ops pointer per helper library. Also often the reuse the same hooks (like atomic does, to facilite conversion from existing drivers using crtc and plane helpers). Given all that it doesn't make sense to put the docs for these next to specific helpers. Instead extract them into a new header file and section in the docbook, and add references to them everywhere. Unfortunately kernel-doc complains when an include directive doesn't find anything (and it does by dumping crap into the output file). We have to remove the now empty includes to avoid that, instead of leaving them in for future proofing. v2: More OCD in ordering functions. v3: Spelling plus collate copyright headers properly.

drm: Move LEAVE/ENTER_ATOMIC_MODESET to fbdev helpers

2015-12-08T15:07:51Z

This is only used for kgdb (and previously panic) handlers in the fbdev emulation, so belongs there. Note that this means we'll leave behind a forward declaration, but once all the helper vtables are consolidated (in the next patch) that will make more sense. v2: fixup radone/amdgpu.

drm: Pass the user drm_mode_fb_cmd2 as const to .fb_create()

2015-11-24T10:47:38Z

Drivers shouldn't clobber the passed in addfb ioctl parameters. i915 was doing just that. To prevent it from happening again, pass the struct around as const, starting all the way from internal_framebuffer_create(). Signed-off-by: Ville Syrjälä Signed-off-by: Daniel Vetter

drm: Add a non-locking version of drm_kms_helper_poll_enable(), v2

2015-09-30T13:04:08Z

drm_kms_helper_poll_enable() was converted to lock the mode_config mutex in commit 8c4ccc4ab6f64e859d4ff8d7c02c2ed2e956e07f ("drm/probe-helper: Grab mode_config.mutex in poll_init/enable"). This disregarded the cases where this function is called from a context where this mutex is already locked. Add a non-locking version as well. Changes since v1: - use function name suffix '_locked' for the function that is to be called from a locked context. Signed-off-by: Egbert Eich Reviewed-by: Daniel Vetter Signed-off-by: Jani Nikula

drm/atomic-helper: Add an atomice best_encoder callback

2015-08-04T09:09:25Z

With legacy helpers all the routing was already set up when calling best_encoder and so could be inspected. But with atomic it's staged, hence we need a new atomic compliant callback for drivers which need to inspect the requested state and can't just decided the best encoder statically. This is needed to fix up i915 dp mst where we need to pick the right encoder depending upon the requested CRTC for the connector. v2: Don't forget to amend the kerneldoc Cc: Chris Wilson Cc: Linus Torvalds Cc: Theodore Ts'o Acked-by: Thierry Reding Reviewed-by: Ander Conselvan de Oliveira Signed-off-by: Daniel Vetter
