2018-07-03drm/vmwgfx: Replace vmw_dma_buffer with vmw_buffer_objectThomas Hellstrom
Initially vmware buffer objects were only used as DMA buffers, so the name DMA buffer was a natural one. However, currently they are used also as dumb buffers and MOBs backing guest backed objects so renaming them to buffer objects is logical. Particularly since there is a dmabuf subsystem in the kernel where a dma buffer means something completely different. This also renames user-space api structures and IOCTL names correspondingly, but the old names remain defined for now and the ABI hasn't changed. There are a couple of minor style changes to make checkpatch happy.

Instead of looking at the (soon to be deprecated) plane->fb we'll examing plane->state->fb instead. We can do this because vmw_du_crtc_atomic_check() prevents us from enabling a crtc without the primary plane also being enabled. Due to that same reason, I'm actually not sure what the checks here are for NULL fb. If we can't enable the crtc without an enabled plane we should always have an fb.

2018-03-21drm/vmwgfx: Fix a destoy-while-held mutex problem.Thomas Hellstrom
When validating legacy surfaces, the backup bo might be destroyed at surface validate time. However, the kms resource validation code may have the bo reserved, so we will destroy a locked mutex. While there shouldn't be any other users of that mutex when it is destroyed, it causes a lock leak and thus throws a lockdep error. Fix this by having the kms resource validation code hold a reference to the bo while we have it reserved. We do this by introducing a validation context which might come in handy when the kms code is extended to validate multiple resources or buffers.

2018-01-09drm/vmwgfx: Don't cache framebuffer mapsThomas Hellstrom
Buffer objects need to be either pinned or reserved while a map is active, that's not the case here, so avoid caching the framebuffer map. This will cause increasing mapping activity mainly when we don't do page flipping. This fixes occasional garbage filled screens when the framebuffer has been evicted after the map. Since in-kernel mapping of whole buffer objects is error-prone on 32-bit architectures and also quite inefficient, we will revisit this later.

2017-03-31drm/vmwgfx: Add and connect plane helper functionsSinclair Yeh
Refactor previous FB and cursor plane update code into their atomic counterparts: check, update, prepare, cleanup, and disable. These helpers won't be called until we flip on the atomic support flag or set drm_crtc_funcs->set_config to using the atomic helper. v2: * Removed unnecessary pinning of cursor surface * Added a few function headers v3: * Set clip region equal to the destination region * Fixed surface pinning policy * Enable SVGA mode in vmw_sou_primary_plane_prepare_fb Signed-off-by: Sinclair Yeh <syeh@vmware.com> Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Reviewed-by: Thomas Hellstrom <thellstrom@vmware.com>
2017-03-31drm/vmwgfx: Add and connect CRTC helper functionsSinclair Yeh
Atomic mode set requires us to refactor existing vmw_stdu_crtc_set_config code into sections that check the validity of the new mode, and sections that actually program the hardware state. vmw_du_crtc_atomic_check() takes CRTC-related checking code. In a later patch, vmw_du_primary_plane_atomic_check() will take framebuffer-related checking code. These helpers won't be called until we flip on the atomic support flag or set drm_crtc_funcs->set_config to using the atomic helper. v2: * The state->num_connector is actually the total number of potential connectors, not just the one associated with the display unit. The proper one to check is ->connector_mask. * Add the check to only allow plane state to be the same as crtc state (Thanks to mlankhorst) * Make sure to turn on SVGA mode before using VRAM. SVGA mode is disabled in master_drop if dbdev is not running. v3: * Moved dot clock override to crtc_atomic_check Signed-off-by: Sinclair Yeh <syeh@vmware.com> Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Reviewed-by: Thomas Hellstrom <thellstrom@vmware.com> Acked-by: Daniel Vetter <daniel@ffwll.ch>
2017-03-31drm/vmwgfx: Connector atomic stateSinclair Yeh
Add connector handling functions. Start tracking is_implicity in the connector state. Eventually, this field should be tracked exclusively in a connector state. Now that plane and connector states have been created, we can also activate the code that use CRTC state.

2017-03-31drm/vmwgfx: Plane atomic stateSinclair Yeh
Add plane state handling functions. We have to keep track of a few plane states so we cannot use the DRM helper for this. Created vmw_plane_state along with functions to reset, duplicate, and destroty it. v2 * Removed cursor clean up special case Signed-off-by: Sinclair Yeh <syeh@vmware.com> Reviewed-by: Thomas Hellstrom <thellstrom@vmware.com> Acked-by: Daniel Vetter <daniel@ffwll.ch>
2017-03-31drm/vmwgfx: CRTC atomic stateSinclair Yeh
Create and Add CRTC state. We currently do not track any properties or custom states so we can technically use the DRM helpers. Creating this code just to make potential future additions easier. Most of the new code will be compiled but not enabled until plane/connector state handling code is also in place. This is the first of a series to enable atomic mode set for vmwgfx. The atomic enabling effort was done in collaboration with Thomas Hellstrom and the VMware Graphics Team.

2017-03-31drm/vmwgfx: Add universal plane supportSinclair Yeh
Universal support is prerequisite for atomic mode set. Explicitly create planes for the cursor and the primary FB. With a functional cursor plane, the DRM will no longer use the legacy cursor_set2 and cursor_move entry points.

2017-03-29drm: Add acquire ctx parameter to ->set_configDaniel Vetter
Surprisingly a lot of legacy drivers roll their own, for runtime pm and because vmwgfx. Also make nouveau's set_config static while at it.
