* Add support for modifiersHEADmasterRobert Foss2017-06-212-2/+14
| | | | | | | | | | Modifiers are used to describe buffer metadata like if and how they are compressed or if tiling is used. This is needed to allow different devices to communicate about buffers that have these properties. Signed-off-by: Robert Foss <robert.foss@collabora.com>
* Add description of GRALLOC_MODULE_PERFORM_GET_DRM_FDRobert Foss2017-06-121-0/+4
| | | | | | Add description of the perform call GRALLOC_MODULE_PERFORM_GET_DRM_FD. Signed-off-by: Robert Foss <robert.foss@collabora.com>

* Add libgralloc_drm library to export headers to mesaRob Herring2017-06-082-0/+14
| | | | | | | | | | Mesa mainline depends on libgralloc_drm shared library for importing include paths. Add a dummy library for this purpose. This gets mesa master building without any additional patches. Patches are still needed for proper functioning.

* Fix missing 0 init of alloc_device_tRob Herring2017-04-131-1/+1
| | | | | | | | This fixes a crash of "dumpsys SurfaceFlinger" because the dump() pointer is not NULL. Change-Id: If4c1f71fd532e21bb246c1b815b8b9ca00bb405b Signed-off-by: Rob Herring <robh@kernel.org>
* Quiet log prints changing them to verbose levelRob Herring2017-04-132-5/+5
| | | | | | | | Quiet down various informational tracing messages switching them to verbose log level Change-Id: I0a78a9bcb1f807dc2db060ab1551cd5f62fa3f2d Signed-off-by: Rob Herring <robh@kernel.org>
* gbm_gralloc: Remove the invalid int cast and assignment in gbm_mod_perform()John Stultz2017-03-291-2/+0
| | | | | | | | | | | | | | | | | | | | | In gbm_mod_perform(), for the cmd GRALLOC_MODULE_PERFORM_GET_USAGE, the code takes the third argument, casts it as an int* and then writes a zero into what the pointer points to. The problem with this is that the third argument to that function is actually a native_handle_t, so writing zero to the first int in that structure ends up overwriting the version value, causing the native_handle_t code to see the value as corrupt. This results in lots of warnings and leaked fds.

* Change module name to gralloc.gbmRob Herring2017-03-221-1/+1
| | | | | | | | | Originally, the intent was to make GBM gralloc a drop-in replacement for DRM gralloc, but this isn't really happening or needed. Change the name so both can coexist. Change-Id: I4eff839523213cc76c56746275d8ba7534ba9c12 Signed-off-by: Rob Herring <robh@kernel.org>
* Fix mapping for non-zero starting coordinatesRob Herring2016-12-131-2/+2
| | | | | | | | | While the gralloc API allows for specifying the starting coordinates (L,T), it seems this doesn't really work. No other gralloc implementations found use the rectangle bounds. Not exactly sure how this ever worked, but it broke recently with AOSP master. Signed-off-by: Rob Herring <robh@kernel.org>
* Add YV12 pixel format supportRob Herring2016-12-131-0/+25
| | | | | | | | GBM doesn't support YV12 and we need a single buffer, so request GR88 from GBM instead and adjust the width and height. GR88 also ensures (hopefully) that the GPU texture alignment requirements are met. Signed-off-by: Rob Herring <robh@kernel.org>
* Remove unused gralloc_drm_handle_t::nameRob Herring2016-12-131-7/+3

* Use alternative GRALLOC_GBM_HANDLE_MAGICEmil Velikov2016-12-131-1/+1
| | | | | | | Using 0x5f47424d ("_GBM") is less likely to colide than the generic 0x12345678. Signed-off-by: Emil Velikov <emil.l.velikov@gmail.com>

* Update usage flag handlingRob Herring2016-04-221-14/+24
| | | | | | | | | | | Add missing support for GRALLOC_USAGE_SW_READ_OFTEN, GRALLOC_USAGE_SW_WRITE_OFTEN, GRALLOC_USAGE_HW_TEXTURE, and GRALLOC_USAGE_CURSOR usage flags mapping them to GBM flags. For now, cursor flag is commented out because the Android side doesn't seem to honor a larger stride. Signed-off-by: Rob Herring <robh@kernel.org>
