Mathias Agopian	72c8508db9	add an offset field to gralloc handles so the framebuffer can work with copybit	2009-06-10 16:06:28 -07:00
Mathias Agopian	5115665397	with the new lock/unlock API we don't really mean reference counting on mmap/munmap because we're guaranteed to map the buffers only once within a process. ... no need to track all handles anymore, which simplifies the code a lot.	2009-06-09 20:50:34 -07:00
Mathias Agopian	485e69809a	better documentation and implementation for lock/unlock	2009-05-05 20:49:49 -07:00
Mathias Agopian	988b8bd553	lock will now return the vaddr of the buffer. map/umap are gone. ... - make sure to return an error if a buffer is locked twice or unlocked while not locked. - added registerBuffer() and unregisterBuffer() to the gralloc module so that we can do some cleanup when a buffer is no longer needed. this became necessary after we removed map/unmap so we have a place to unmap buffers without the need of a kernel module. - change the constants for GRALLOC_USAGE_SW_{READ|WRITE}_NEVER to 0, so that NOT specifying them means "NEVER".	2009-05-04 14:26:56 -07:00
