* freedreno: completely untested initial supportRob Clark2015-01-161-0/+2
| | | | | | | | | v2: [Emil Velikov] - drmGetVersion returns the kernel module name. - Add it to the build :) - freedreno_map returns void * while gralloc::map expects int. Signed-off-by: Emil Velikov <emil.l.velikov@gmail.com>
* gralloc: provide methods for hwc to change handle of a planeTapani Pälli2013-05-131-1/+7
| | | | | | | | | | | | | Patch changes reserve_plane to get id number as additional parameter. This can be used by hwc to make changes to a particular plane. New api hwc_set_plane_handle is introduced so that hwc can change the buffer handle of a plane, this is required because after plane has been reserved for a particular ui layer, this handle can change as the layer is typically multibuffered.

* gralloc: check possible crtcs of plane against primary outputTapani Pälli2013-05-071-0/+1
| | | | | | | | | Current implementation supports planes only with primary output, patch adds a check to guard this. Change-Id: I537858122a4fe77a374031d11339eaaea27ad9bf Signed-off-by: Tapani Pälli <tapani.palli@intel.com> Reviewed-by: Topi Pohjolainen <topi.pohjolainen@intel.com>
* gralloc: plane supportTapani Pälli2013-04-151-0/+25
| | | | | | | | | | | | patch introduces API between hwcomposer and gralloc, hwcomposer can reserve an overlay plane to be used by a particular layer in prepare hook, drmModeSetPlane for each plane gets called later when post() gets called by the eglSwapBuffers (from hwcomposer set), this can be later changed to use atomic modesetting code and drm properties to make one 'atomic flip' for graphics + planes.

* gralloc: use proper mode for hdmi outputTapani Pälli2013-03-011-0/+3
| | | | | | | | | | | | Patch uses the best mode available on hdmi output and creates a private buffer that is used for pageflipping. Primary display content is copied to private buffer on each page flip. This patch removes current hack where same mode is assumed from hdmi output, this caused graphical artifacts with some tv's. Also some more debug output is added. Change-Id: Ic862a8374f46992f0ff92545da8a010f9684b934 Signed-off-by: Tapani Pälli <tapani.palli@intel.com>
* gralloc: change copy api and fix copy function for intelTapani Pälli2013-03-011-3/+6
| | | | | | | | | | | | | | | | Patch extends current copy api, renames it blit and introduces src+dst coordinates to be able to implement partial blits and blits with offsets. Implementation must take care of hw specific restrictions with blits. Patch also fixes issues with the current intel_blit function. Current implementation does not select ring buffer and ends up queuing blit commands to the render ring. Patch starts to use drm_intel_bo_mrb_exec to be able to select blit ring and fixes the checks inside copy function.

* gralloc: hdmi cloned mode supportTapani Pälli2012-10-241-5/+25
| | | | | | | | | | | | | | | | | | Patch implements simple support for cloned mode hdmi by introducing primary and hdmi outputs that are updated respectively. Current implementation is rather naive and assumes hdmi can drive same mode as the local lvds. Only cloned mode is supported but can be extended later to support extended mode when hwcomposer is available for controlling this behaviour. HDMI hotplug is implemented as a separate observer thread that listens to uevents and reads hdmi connection state from there, this requires switch support from the kernel hdmi driver.

* gralloc: add refcount to gralloc_drm_bo_tTapani Pälli2012-10-121-0/+2
| | | | | | | | | | This is an basic enabler for gralloc to let buffers live while they are still in use by gralloc (for example during scanout), otherwise Android may choose to destroy them while they are still needed. This facility will get used with upcoming plane support and direct rendering support. Change-Id: I2f0bc595846a68e8d2feb5138b022d16f207e2b5 Signed-off-by: Tapani Pälli <tapani.palli@intel.com>
* vmwgfx: assorted fixesChia-I Wu2011-08-241-1/+1
| | | | | | | | | | | Based on trial and error, we know - drm_kms_wait_for_post() hangs the VM - drmModeDirtyFB() should be called whenever the front buffer changes - drmModePageFlip() is not supported They might not be entirely correct, but fixing them makes drm_gralloc work.
