2013-11-18media: nvmap: Few tweaks in nvmapVikram Fugro
The tweaks are only specific to r16-r2 branch and will not go into mainline. - Pass nvmap memory handle to the user through the mmap'd buffer allocated by videobuf2 client. - Allow the "user" nvmap client to access the nvmap memory handle of "videobuf2-dma-nvmap" client. Re-arranging the copyright message in nvmap_dev.c for Automatic validation to pass.

2012-08-27video: tegra: nvmap: fix handle usecount trackingTuomas Tynkkynen
A handle's usecount used to be incremented once during the mmap ioctl, and decremented when the mapping is closed by the kernel. However, that fails if a mapping cloned, for example if the mapping was split due to a munmap, or (presumably) during fork, as the decrement will then happen for each cloned mapping. Therefore increment the usecount when a mapping is opened. Also fix a BUG_ON() that would have caught this bug, if it wouldn't have done the check by checking if the unsigned usecount field is less than zero.

2011-11-30video: tegra: add GPU memory management driver (nvmap)Gary King
nvmap provides an interface for user- and kernel-space clients to allocate and access memory "handles" which can be pinned to enable the memory to be shared with DMA devices on the system, and may also be mapped (using caller-specified cache attributes) so that they are directly accessible by the CPU. the memory handle object gives clients a common API to allocate from multiple types of memory: platform-reserved physically contiguous "carveout" memory, physically contiguous (order > 0) OS pages, or physically discontiguous order-0 OS pages that can be remapped into a contiguous region of the DMA device's virtual address space through the tegra IOVMM subsystem. unpinned and unmapped memory handles are relocatable at run-time by the nvmap system. handles may also be shared between multiple clients, allowing (for example) a window manager and its client applications to directly share framebuffers Change-Id: Ie8ead17fe7ab64f1c27d922b1b494f2487a478b6 Signed-off-by: Gary King <gking@nvidia.com>
