2016-11-16drm/irq: Unexport drm_vblank_on/offDaniel Vetter3-64/+23
Only remaining use was in amdgpu, and trivial to convert over to drm_crtc_vblank_* variants.

2016-11-16drm/irq: Unexport drm_vblank_countDaniel Vetter2-28/+11
No one outside of drm_irq.c should ever need this. The correct way to implement get_vblank_count for hw lacking a vblank counter is drm_vblank_no_hw_counter. Fix this up in mtk, which is the only offender left over.

2016-11-16drm/irq: Make drm_vblank_pre/post_modeset internalDaniel Vetter2-41/+6
Now that all drivers are switched over to drm_crtc_vblank_on/off we can relegate pre/post_modeset to the purely drm_irq.c internal role of supporting old ums userspace. As usual switch to the drm_legacy_ prefix to make it clear this is for old drivers only. v2: Rebase on top of Thierry's s/int crtc/unsigned int pipe/ changes.

2016-11-16drm/nouveau: Use drm_crtc_vblank_off/onDaniel Vetter2-10/+6
With atomic nv50+ is already converted over to them, but the old display code is still using it. Found in a 2 year old patch I have lying around to un-export these old helpers! v2: Drop the hand-rolled versions from resume/suspend code. Now that crtc callbacks do this, we don't need a special case for s/r anymore. v3: Remove unused variables. v4: Don't remove drm_crtc_vblank_off from suspend paths, non-atomic nouveau still needs that. But still switch to drm_crtc_vblank_off since drm_vblank_off will disappear.

2016-11-15Revert "drm: Add aspect ratio parsing in DRM layer"Ville Syrjälä1-31/+0
This reverts commit 6dffd431e2296cda08e7e4f0242e02df1d1698cd. Adding new mode flags willy nilly breaks existing userspace. We need to coordinate this better, potentially with a new client cap that only exposes the aspect ratio flags when userspace is prepared for them (similar to what we do with stereo 3D modes). This also broke things so that we would always send out VIC==0 in the AVI infoframe unless the user specified an aspect ratio via the mode flags. And the automagic RGB full vs. limited range handling was similartly broken as the user mode would never match any CEA mode.

2016-11-14drm/fb_cma_helper: Add drm_fb_cma_prepare_fb() helperMarek Vasut2-0/+38
Add new drm_fb_cma_prepare_fb() helper function extracted from the imx-drm driver. This function checks if the plane has DMABUF attached to it, extracts the exclusive fence from it and attaches it to the plane state for the atomic helper to wait on it.

2016-11-14drm/gma500: use DRM_FB_HELPER_DEFAULT_OPS for fb_opsStefan Christ1-9/+3
This refactoring leads to real functional changes in the driver. Now the struct psbfb_ops implements two additional members: .fb_setcmap = drm_fb_helper_setcmap, .fb_pan_display = drm_fb_helper_pan_display, and the struct psbfb_roll_ops implements one additional member: .fb_setcmap = drm_fb_helper_setcmap, and the struct psbfb_unaccel_ops implements two additional members: .fb_setcmap = drm_fb_helper_setcmap, .fb_pan_display = drm_fb_helper_pan_display, These changes are not tested.

2016-11-14drm/fb-helper: fix segfaults in drm_fb_helper_debug_*Stefan Christ1-0/+6
A drm driver that is implementing fb_debug_enter and fb_debug_leave in struct fb_ops with drm fb helper functions drm_fb_helper_debug_enter and drm_fb_helper_debug_leave must also implement the callback 'mode_set_base_atomic' in struct drm_crtc_helper_funcs. See Documentation/DocBook/kgdb.tmpl. The current implementation will segfault when 'mode_set_base_atomic' is a NULL pointer. Before this patch at least the drm drivers armada, ast, qxl, udl and virtio do not have a 'mode_set_base_atomic' implementation but using drm_fb_helper_debug_(enter|leave). So these drivers may segfault when callbacks fb_debug_(enter|leave) are called. Avoid the issue by just checking for NULL pointers. So all drivers can unconditionally implement fb_debug_(enter|leave) with the drm_fb_helper functions. If callback 'mode_set_base_atomic' is not implemented, the code in drm_fb_helper_debug_(enter|leave) does effectively nothing.

2016-11-12drm: move allocation out of drm_get_format_name()Eric Engestrom17-87/+82
The function's behaviour was changed in 90844f00049e, without changing its signature, causing people to keep using it the old way without realising they were now leaking memory. Rob Clark also noticed it was also allocating GFP_KERNEL memory in atomic contexts, breaking them. Instead of having to allocate GFP_ATOMIC memory and fixing the callers to make them cleanup the memory afterwards, let's change the function's signature by having the caller take care of the memory and passing it to the function. The new parameter is a single-field struct in order to enforce the size of its buffer and help callers to correctly manage their memory.
