* | drm: rcar-du: Replace LVDS encoder DPMS by enable/disableLaurent Pinchart2015-03-034-23/+21
| | | | | | | | | | | | | | | | The LVDS encoder doesn't support DPMS states, replace the DPMS operation by enable/disable to avoid propagating DPMS states down to the encoder code. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
* | drm: rcar-du: Remove private copy of plane size and positionLaurent Pinchart2015-03-032-23/+10
| | | | | | | | | | | | | | | | The plane source and destination size and positions are stored in the plane state, and a private copy is kept in the rcar_du_plane objects. Remove the private copy as it just duplicates the state. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
* | drm: rcar-du: Wire up atomic state object scaffoldingLaurent Pinchart2015-03-036-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | Hook up the default .reset(), .atomic_duplicate_state() and .atomic_free_state() helpers to ensure that state objects are properly created and destroyed, and call drm_mode_config_reset() at init time to create the initial state objects. Framebuffer reference count also gets maintained automatically by the transitional helpers except for the legacy page flip operation. Maintain it explicitly there.

* | drm: rcar-du: Handle primary plane config through atomic plane opsLaurent Pinchart2015-03-033-78/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use the new CRTC atomic transitional helpers drm_helper_crtc_mode_set() and drm_helper_crtc_mode_set_base() to implement the CRTC .mode_set and .mode_set_base operations. This delegates primary plane configuration to the plane .atomic_update and .atomic_disable operations, removing duplicate code from the CRTC implementation. There is now no code path available to the driver in which to drop the reference to the CRTC acquired in the .prepare() operation if an error then occurs. The driver thus now leaks a reference if an error occurs during mode set. So be it, this will be fixed in a further step of the atomic update transition.

* | drm: rcar-du: Implement planes atomic operationsLaurent Pinchart2015-03-032-48/+141
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement the CRTC .atomic_begin() and .atomic_flush() operations, the plane .atomic_check(), .atomic_update() and operations, and use the transitional atomic helpers to implement the plane update and disable operations on top of the new atomic operations. The plane setup code can't be moved out of the CRTC start function completely yet, as the atomic code paths are not taken every time the CRTC needs to be started. This results in some code duplication that will be fixed after switching to atomic updates completely. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
* | drm: rcar-du: Fix hardware plane allocationLaurent Pinchart2015-03-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | The hardware plane allocator loops over all planes to find free candidates. However, instead of looping over the number of hardware planes, it loops over the number of software planes, which happens to be larger by one unit. This has no effect in practise as the extra plane is always cleared in the mask of free planes, but it should still be fixed for correctness.

* | drm: rcar-du: Implement universal plane supportLaurent Pinchart2015-03-034-52/+40
| | | | | | | | | | | | | | | | | | | | | | Explicitly create the CRTC primary plane instead of relying on the core helpers to do so. This simplifies the plane logic by merging the KMS and software planes. Reject plane API operations on the primary planes for now, as that code will anyway be refactored when implementing support for atomic updates.

* | drm: rcar-du: Disable fbdev emulation when no connector is presentLaurent Pinchart2015-03-031-5/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | fbdev emulation requires at least one connector, and will fail to initialize if no connector has been successfully instantiated. Disable it in that case and print an informational message instead of failing probe with a confusing fbdev emulation error message. It could be argued that probe should fail when no connector is present, but the DU could still be useful in that case with the to-be-implemented memory write-back support.

* | drm: rcar-du: Turn vblank on/off when enabling/disabling CRTCLaurent Pinchart2015-03-032-11/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DRM core vblank handling mechanism requires drivers to forcefully turn vblank reporting off when disabling the CRTC, and to restore the vblank reporting status when enabling the CRTC. Implement this using the drm_crtc_vblank_on/off helpers. When disabling vblank we must first wait for page flips to complete, so implement page flip completion wait as well. Finally, drm_crtc_vblank_off() must be called at startup to synchronize the state of the vblank core code with the hardware, which is initially disabled. This is performed at CRTC creation time, requiring vertical blanking to be initialized before creating CRTCs. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DRM slave encoders require their associated struct drm_encoder instance to be embedded in a struct drm_slave_encoder. This makes processing encoders regardless of their types needlessly and painfully complex in drivers that use a mix of slave encoders and custom encoders. Such a driver will need to either create drm_slave_encoder instances that fake their embedded encoder instance, or to turn all drm_encoder instances into drm_slave_encoder instances.

While the include/uapi/drm/drm_mode.h header has a comment denoting them as outputs, that seemingly wasn't enough to make drivers use them properly. The result is that some userspace doesn't explicitly zero out those fields, assuming that the kernel won't use them. That causes problems since the data within the structure might be uninitialized, so bogus data may end up confusing drivers (ridiculously large values for the pitch, ...). This series attempts to improve the situation by fixing all drivers to not use the output fields. Furthermore to spare new drivers this bad surprise, the DRM core now zeros out these fields prior to handing the data structure to the driver. Lessons learned from this are that future IOCTLs should be properly documented (in the DRM DocBook for example) and should be rigorously defined. To prevent misuse like this, userspace should be required to zero out all output fields. The kernel should check for this and fail if that's not the case. * tag 'drm/gem-cma/for-3.19-rc1' of git://people.freedesktop.org/~tagr/linux: drm/cma: Remove call to drm_gem_free_mmap_offset() drm: Sanitize DRM_IOCTL_MODE_CREATE_DUMB input drm/rcar: gem: dumb: pitch is an output drm/omap: gem: dumb: pitch is an output drm/cma: Introduce drm_gem_cma_dumb_create_internal() drm/doc: Add GEM/CMA helpers to kerneldoc drm/doc: mm: Fix indentation drm/gem: Fix a few kerneldoc typos

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When creating a dumb buffer object using the DRM_IOCTL_MODE_CREATE_DUMB IOCTL, only the width, height, bpp and flags fields are inputs. The caller is not guaranteed to zero out or set handle, pitch and size. Drivers must not treat these values as possible inputs, otherwise they may use uninitialized memory during the computation of the framebuffer size. The R-Car DU driver treats the pitch passed in from userspace as minimum and will only overwrite it when the driver-computed pitch is larger, allowing userspace to, intentionally or not, overallocate framebuffers.

| | * drm/cma: Introduce drm_gem_cma_dumb_create_internal()Thierry Reding2014-11-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This function is similar to drm_gem_cma_dumb_create() but targetted at kernel internal users so that they can override the pitch and size requirements of the dumb buffer. It is important to make this difference because the IOCTL says that the pitch and size fields are to be considered outputs and therefore should not be used in computations of the framebuffer size. Internal users may still want to use this code to avoid duplication and at the same time pass on additional, driver-specific restrictions on the pitch and size. While at it, convert the R-Car DU driver, the single user that overrides the pitch, to use the new internal helper.

* drm: add driver->set_busid() callbackDavid Herrmann2014-09-101-0/+1
| | | | | | | | | | | | | | One step closer to dropping all the drm_bus_* code: Add a driver->set_busid() callback and make all drivers use the generic helpers. Nouveau is the only driver that uses two different bus-types with the same drm_driver. This is totally broken if both buses are available on the same machine (unlikely, but lets be safe). Therefore, we create two different drivers for each platform during module_init() and set the set_busid() callback respectively.

* drm/rcar-du: Fix maximum frame buffer pitch computationLaurent Pinchart2014-07-301-2/+11
| | | | | | | | | | The maximum pitch constraint for the hardware is expressed in pixels. Convert it to bytes to validate frame buffer creation, as frame buffer pitches are expressed in bytes.

* drm: Replace crtc fb with primary plane fb (v3)Matt Roper2014-04-011-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | Now that CRTC's have a primary plane, there's no need to track the framebuffer in the CRTC. Replace all references to the CRTC fb with the primary plane's fb. This patch was generated by the Coccinelle semantic patching tool using the following rules: @@ struct drm_crtc C; @@ - (C).fb + C.primary->fb @@ struct drm_crtc *C; @@ - (C)->fb + C->primary->fb v3: Generate patch via coccinelle. Actual removal of crtc->fb has been moved to a subsequent patch. v2: Fixup several lingering crtc->fb instances that were missed in the first patch iteration.
