* Use private_0 flag * Add some legacy flags to be used during transition * Fix gralloc module version * Adjust makefiles for gralloc1 * Add support for dump, num flex planes and lock flex. * Use a unique ID for buffer descriptors * Do not delete buffer handle, fix after verifying framework fix. * Current gralloc1 clients do not conform to the lock() requirement in the gralloc1 header. Tracked in b/33588773 * Add perform APIs to get the buffer size and allocate a buffer for use by SDM * Fix reference counting * Add a unique buffer ID * Some cleanup in private_handle * Create a wrapper class of private_handle to do refcounting * Resolve implementation defined formats At allocation time, update buffer descriptors to replace implementation defined formats with the ones we mean to allocate * Defer ion handle release * Remove unused drm code. * Add legacy constructor for private_handle_t used by some clients CRs-Fixed: 2007391 Change-Id: Ia9e816cec35ba45483a5b75d99f256325a010138
