Add a macro to iterate across nvgpu_sgts. This makes it easier on
developers who may accidentally forget to move to the next SGL.

For Simualtion/Emulation platforms,clock gating
should be skipped as it is not supported.
Added new flags "can_"X"lcg" to check platform
capability before doing SLCG,BLCG and ELCG.

Rename get_physical_addr_bits and related functions to something that
more clearly conveys what they are doing. The basic idea of these
functions is to translate from a physical GPU address to a IOMMU GPU
address. To do that a particular bit (that varies from chip to chip)
is added to the physical address.

Add a function to do address translation for IOMMU capable GPUs.
When an iGPU is behind and IOMMU it can pick whether to use that
IOMMU for translation by adding a bit to physical addresses. This
function takes care of that.
However, this required an abstracted nvgpu_iommuable() API to
check whether a GPU is behind an IOMMU. This patch adds that API
for Linux.

Remove the last sg_phys() call from the GMMU code and replace it
with a generic nvgpu_mem API. This new API, nvgpu_mem_get_phys_addr(),
returns the physical address of an nvgpu_mem struct.
Also, implement this new API in the Linux specific nvgpu_mem code
since it requires access to the underlying SGT/SGL.

This change solves two problems:
(*) the possibility of a crash due to interrupting the gpu
initialization following a bind
(*) a IOVA memory leak that could prevent the GPU from binding after
about 200 bind/unbind cycles
A detailed list of fixes:
- chek that arbiter is initialized before freeing it.
- do not re-enable interrupts when MSI is enabled on unbind.
- free the semaphore sea on unbind.
- ensure we dont double load the vbios.
- check return value of nvgpu_mutex_init for semaphores.
- add corresponding nvgpu_mutex_destroy calls.

The basic nvgpu_mem_sgl implementation provides support
for OS specific scatter-gather list implementations by
simply copying them node by node. This is inefficient,
taking extra time and memory.
This patch implements an nvgpu_mem_sgt struct to act as
a header which is inserted at the front of any scatter-
gather list implementation. This labels every struct
with a set of ops which can be used to interact with
the attached scatter gather list.
Since nvgpu common code only has to interact with these
function pointers, any sgl implementation can be used.
Initialization only requires the allocation of a single
struct, removing the need to copy or iterate through the
sgl being converted.

The last major item preventing the core MM code in the nvgpu
driver from being platform agnostic is the usage of Linux
scattergather tables and scattergather lists. These data
structures are used throughout the mapping code to handle
discontiguous DMA allocations and also overloaded to represent
VIDMEM allocs.
The notion of a scatter gather table is crucial to a HW device
that can handle discontiguous DMA. The GPU has a MMU which
allows the GPU to do page gathering and present a virtually
contiguous buffer to the GPU HW. As a result it makes sense
for the GPU driver to use some sort of scatter gather concept
so maximize memory usage efficiency.
To that end this patch keeps the notion of a scatter gather
list but implements it in the nvgpu common code. It is based
heavily on the Linux SGL concept. It is a singly linked list
of blocks - each representing a chunk of memory. To map or
use a DMA allocation SW must iterate over each block in the
SGL.
This patch implements the most basic level of support for this
data structure. There are certainly easy optimizations that
could be done to speed up the current implementation. However,
this patches' goal is to simply divest the core MM code from
any last Linux'isms. Speed and efficiency come next.

Make the kmem debugging prints much more easily usable. Previously the
prints would only take effect if the full tracking was enabled:
CONFIG_NVGPU_TRACK_MEM_USAGE
However, there are many times when just the debug prints would be nice
to have by simply setting the log mask bit in the log mask.
echo 0x80000 > /sys/kernel/debug/<gpu>/log_mask
Also this change now uses the real nvgpu_log() function instead of the
legacy nvgpu_dbg() function. This makes the logging appear with proper
GPU printing as well.

Add a function to check if an nvgpu_mem is allocated (valid) or not.
Also fix possibly leaked state in nvgpu_mems when they fail to
allocate.
Also ensure that in the case of a failure to allocate no state is
accidentally leaked to the caller. This should hopefully make it
less likely that a caller thinks a buffer that failed to allocate
is actually allocated.

We right now remove a channel from TSG list and disable all the channels in
TSG while removing a channel from TSG
With this sequence if any one channel in TSG is closed, rest of the channels
are set as timed out and cannot be used anymore
We need to fix this sequence as below to allow removing a channel from active
TSG so that rest of the channels can still be used
- disable all channels of TSG
- preempt TSG
- check if CTX_RELOAD is set if support is available
if CTX_RELOAD is set on channel, it should be moved to some other channel
- check if FAULTED is set if support is available
- if NEXT is set on channel then it means channel is still active
print out an error in this case for the time being until properly handled
- remove the channel from runlist
- remove channel from TSG list
- re-enable rest of the channels in TSG
- clean up the channel (same as regular channels)
Add below fifo operations to support checking channel status
g->ops.fifo.tsg_verify_status_ctx_reload
g->ops.fifo.tsg_verify_status_faulted
Define ops.fifo.tsg_verify_status_ctx_reload operation for gm20b/gp10b/gp106
as gm20b_fifo_tsg_verify_status_ctx_reload()
This API will check if channel to be released has CTX_RELOAD set, if yes
CTX_RELOAD needs to be moved to some other channel in TSG
Remove static from channel_gk20a_update_runlist() and export it

Due to a h/w bug in Maxwell and Pascal we first need to enable all channels with
NEXT and CTX_RELOAD set in a TSG, and then rest of the channels should be
enabled
Add this sequence to gk20a_tsg_enable()
Add new APIs to enable/disable scheduling of TSG runlist
gk20a_fifo_enable_tsg_sched()
gk20a_fifo_disble_tsg_sched()
Add new APIs to check if channel has NEXT or CTX_RELOAD set
gk20a_fifo_channel_status_is_next()
gk20a_fifo_channel_status_is_ctx_reload()

Explicitly page align DMA memory allocations. Non-page aligned
DMA allocs can lead to nvgpu_mem structs that have a size that's
not page aligned. Those allocs, in some cases, can cause vGPU
maps to return an error.
More generally DMA allocs in Linux are never going to not be
page aligned both in size and address. So might as well page align
the alloc size to make code else where in the driver more simple.
To imlpement this an aligned_size field has been added to struct
nvgpu_mem. This field has the real page aligned size of the
allocation. The original size is still saved in size.

Remove debugging features that did not really get used and make
the debugging code use the nvgpu_log() functionality. This ties
the allocator debugging into the larger nvgpu debug framework.
Also modify many of the places CONFIG_DEBUG_FS was used to
conditionally compile allocator debug code to use __KERNEL__
instead. This is because that debug code can still be called even
when debugfs is not present in Linux.

Remove the mm.get_iova_addr() HAL and replace it with a new HAL
called mm.gpu_phys_addr(). This new HAL provides the real phys
address that should be passed to the GPU from a physical address
obtained from a scatter list. It also provides a mechanism by
which the HAL code can add extra bits to a GPU physical address
based on the attributes passed in. This is necessary during GMMU
page table programming.
Also remove the flags argument from the various address functions.
This flag was used for adding an IO coherence bit to the GPU
physical address which is not supported.
