As the syncpoint state is saved and restored automatically by the host driver a cpu increment of a syncpoint in the powered down state will be lost. Also adds checks for host module being powered. ** video: tegra: fb: add ioctl to flip dc windows to nvmap handles tegra user-space graphics drivers may allocate framebuffers using nvmap rather than rendering to the common framebuffer, this may be done to support deeper buffer pipelining, color formats and pixel layouts other than the initial bootup framebuffer, etc. to use this ioctl, a caller must first specify an nvmap fd which is already open in the calling process so that the subsequent flip ioctls may be properly validated. flips are performed asynchronously, with flip completion notifications provided back to the caller via the host1x syncpoint mechanism based on earlier changes made by Antti Hatala <ahatala@nvidia.com> and Erik Gilling <konkers@android.com> Change-Id: I4e8a8bb92085a485d65fd87d89112b2969ee37ff Signed-off-by: Gary King <gking@nvidia.com> |
