video: tegra: dc: use nvhost driver for host1x power management

Incrementing the frame done syncpoint value from the display interrupt
requires that the host module is powered on. 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.

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

video: tegra: host1x driver

the graphics and display hardware on tegra SoCs is accessed
through a command DMA front-end called host1x

host driver clients place commands into memory objects called
streams, and submit a stream on one of 8 channels: the assignment
of streams-to-channels depends on the hardware module(s) programmed
by the stream: for example, all streams which program the 3D
hardware are submitted on channel 1.

the host1x hardware includes two synchronization primitives to
allow command streams to synchronize access to memory or to
hardware engines shared across channels (e.g. the 2D blitter):
sync points and module mutexes. both primitives can also be
used to synchronize with the CPU.

the host1x driver performs power management for all modules
behind the host block: once a module is idle (i.e., the
last stream which accesses it has completed, indicated by
a syncpoint) and has remained idle for an extended period
of time, the module's clock (and power gate island, if the
module is uniquely power-gated) is disabled, and will be
automatically re-enabled when a new stream is submitted for
that module.

video: tegra: add GPU memory management driver (nvmap)

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

this results in cachelines being allocated in SMP which are not

both CPUs, the aggregate write bandwidth is just 500MB/sec

changing the cache allocation policy to read-allocate reduces some

ARM CPUs with speculative prefetching have undefined behaviors when the

conflicting cache attributes.

since many recent systems include IOMMU functionality (i.e., remapping
of discontiguous physical pages into a virtually-contiguous address
range for I/O devices), it is desirable to support allocating any
available OS memory for use by the I/O devices. however, since many
systems do not support cache coherency between the CPU and DMA devices,

(which severely limits the benefit of an IOMMU) or performing cache
maintenance (which can be a severe performance loss, particularly on
systems with outer caches, compared to using DMA-coherent memory).

cache maintenance properties and ensures that the kernel's mapping
of the page reflects the desired cache attributes, in line with the

On suspend, while we are killing read urbs, some of the urbs
might succeed. Don't re-submit them and wait for the workqueue
to process them.

Fixed urbs ref count
