Currently, host1x power refcount may decrement
to 0, while GPU is still powered on and we're still
servicing IRQs. So to prevent this situation,,
take a ref while GPU is being powered on, and
decrement it during power off. Since we are always
holding one reference while GPU is powered on,
we can remove this handling from gk20a_busy/idle()

When managing GVA spaces the buddy allocator requires PDE size
alignment. This is to ensure that PTE size in buddies always
remains consistent.
Consider the following hypothetical GVA space: it is 32 elements
long, order 0 block size is 1, and PDE size is 8. This leads to:
Base: 8
Size: 24
Managed space: [8, 32)
The start of the space will be 8 (base must be aligned to a PDE
and we need a hole at the bottom for handling errors). Size is
simply the max, 32, minus what we cut out for the low hole. The
two top level buddies are [8 -> 24), and [24 -> 32).
Now, suppose, instead the base were 4:
Base: 4
Size: 28
Managed space: [4, 32)
The top level buddies would be [4 -> 20), [20 -> 28), and [28 -> 32).
This presents several problems: none of the buddies are PDE aligned
and one top level buddy is smaller than the PDE size. The simplest
issue is how to determine the PTE size of the [28 -> 32) block. We
can just set it as small but that's not ideal. The bigger issue is
the mis-alignment of the larger buddies. [20 -> 28) is halfway in
one PDE and halfway in another. That means the allocator would have
to manage the two sub-buddies [20 -> 24) and [24 -> 28) separately.
Instead of dealing with the above issues in the allocator it is much
more simple to require that any GVA space is PDE aligned since they
are already massive and already, in practice, have this alignment.

with the gmmu_page_size_* enum. This patch makes the buddy allocator
use the gmmu_page_size_* fields and now has only BALLOC_PTE_SIZE_ANY
for when the allocator does not care about PTE size.

Implement a bitmap allocator for GPU use. This allocator is useful for
managing memory (or resource) regions where the buddy allocator is not
ideal. Some instances are small regions or where the resource management
must not make calls to the kernel's memory allocation routines (anything
that ultimately calls alloc_page()).
The code path where this avoidance of alloc_page() is most required is
the gpfifo submit path. In order to keep this routine fast and have
predicable time constraints no alloc_page() calls is necessary. The
buddy allocator does not work for this since every time a buddy is
allocated there is the possibility that a pair (or more) buddy structs
have to be made. These allocs could perhaps require a call into
alloc_page() if there is not enouch space in the kmem_cache slab for
the buddy structs.

Support multiple types of allocation backends. Currently there is
only one allocator implementation available: a buddy allocator.
Buddy allocators have certain limitations though. For one the
allocator requires metadata to be allocated from the kernel's
system memory. This causes a given buddy allocation to potentially
sleep on a kmalloc() call.
This patch has been created so that a new backend can be created
which will avoid any dynamic system memory management routines
from being called.

For devices that have vidmem available, use the vidmem allocator in
gk20a_gmmu_alloc{,attr,_map,_map_attr}. For others, use sysmem.
Because all of the buffers haven't been tested to work in vidmem yet,
rename calls to gk20a_gmmu_alloc{,attr,_map,_map_attr} to have _sys at
the end to declare explicitly that vidmem is used. Enabling vidmem for
each now is a matter of removing "_sys" from the function call.

We currenlty initialize both runtime PM and pm_domains frameworks
and use pm_domain to control runtime power management of NvGPU
But since GPU has a separate rail, using pm_domain is not
strictly required
Hence remove pm_domain support and use runtime PM only for all
the power management
This also simplifies the code a lot
Initialization in gk20a_pm_init()
- if railgate_delay is set, set autosuspend delay of runtime PM
- try enabling runtime PM
- if runtime PM is now enabled, keep GPU railgated
- if runtime PM is not enabled, keep GPU unrailgated
- if can_railgate = false, disable runtime PM and keep
GPU unrailgated
Set gk20a_pm_ops with below callbacks for runtime PM
static const struct dev_pm_ops gk20a_pm_ops = {
.runtime_resume = gk20a_pm_runtime_resume,
.runtime_suspend = gk20a_pm_runtime_suspend,
.resume = gk20a_pm_resume,
.suspend = gk20a_pm_suspend,
}
Move gk20a_busy() to use runtime checks of pm_runtime_enabled()
instead of using compile time checks on CONFIG_PM
Clean up some pm_domain related code
Remove use of gk20a_pm_enable/disable_clk() since this
should be already done in platform specific unrailgate()/
railgate() APIs
Fix "railgate_delay" and "railgate_enable" sysfs to use
runtime PM calls
For VGPU, disable runtime PM during vgpu_pm_init()
With this, we will initialize vgpu with vgpu_pm_finalize_poweron()
upon first call to gk20a_busy()
