In gk20a.h, we use these multichar constants
'DONE', '0R32', '0W32'
But these constants fail compilation on some cross-os compilers
Hence remove them by creating a specific MULTICHAR_TAG()
All the User space components also form these constants in similar
fashion

Conditionally compile debug_kmem.c in the Makefile since the entire
file is not needed when CONFIG_NVGPU_TRACK_KMEM_USAGE is not enabled.
Removing as many conditional compilation flags from the C code itself
is highly desirable from a code complexity standard.

Add abstraction of IO aperture accessors. Add new functions
gk20a_io_exists() and gk20a_io_valid_reg() to remove dependencies to
aperture fields from common code.
Implement Linux version of the abstraction by moving gk20a_readl()
and gk20a_writel() to new Linux specific io.c. Move the fields
defining IO aperture to nvgpu_os_linux.
Add t19x specific IO aperture initialization functions and add t19x
specific section to nvgpu_os_linux.

Reduce the usage of nvgpu_vidmem_get_page_alloc() and friends as much
as possible. This reduces the dependency of nvgpu on Linux SGLs. SGLs
still need to be used, however, since sharing buffers in userspace is
done by dma_buf FD. The best way to pass the vidmem buf through the
dma_buf is by SGL pointer.

that defines the vidmem buffer in the core MM code. The Linux code

While unbindin a channel from TSG, we first disable all the channels,
then examine the status of channel being removed in
gk20a_fifo_tsg_unbind_channel_verify_status(), and if this API fails we
re-enable all the channel and kill whole TSG
And in gk20a_fifo_tsg_unbind_channel_verify_status() we first check ctx_reload
and fault status and then check NEXT status
If channel has NEXT set we bail out
But since we have already changed the TSG ctx_reload status re-enabling all
channels in TSG might cause issues
Hence fix this by correcting sequence so that we first ensure that NEXT is
not set on channel and then only alter the status

Some GPUs require all channels to be on TSG and also have larger than 4GB
vidmem sizes which were not supported on the previous CE2 code.
This change creates a new property to track if the copy engine needs to
encapsulate its kernel context on tsg and also modifies the copy engine code
to support much larger copies without dramatically increasing the PB size.

Change the wait for work pending condition to interruptible in the
channel worker thread, as there's no reason to be noninterruptible.
A noninterruptible wait, even one with a timeout, causes the worker to
be printed in the Linux blocked tasks list which is confusing.
Change the cond signal to interruptible to match this.

When freeing kmalloc and vmalloc buffers memset them to zero
before freeing them with the kernel APIs. This is only done if
CONFIG_NVGPU_TRACK_MEM_USAGE is set since this adds obvious
overhead to the driver. However, it is an incredibly useful
debug tool, so it's nice to have.
This could be done by enabling Linux kernel configs as well,
but not all OSes may have such a feature so building it into
nvgpu may prove quite useful.

Pre-os firmware takes care, among others, of the control of FAN till
the driver takes over its control. On some GPUs not enabling this FW can lead
tp physical board damage, hence it is needed to run this firmware.

vgpu inherits the HAL from the native implementation.
But currently, the tsg_veriy_channel_status entry point is
not supported on vgpu, so make sure to NULL it.

PRAMIN batch access functions are only used by nvgpu_mem. The way
the functions are written is Linux specific, so move the

Split VIDMEM support into its own code files organized as such:
common/mm/vidmem.c - Base vidmem support
common/linux/vidmem.c - Linux specific user-space interaction
include/nvgpu/vidmem.h - Vidmem API definitions
Also use the config to enable/disable VIDMEM support in the makefile
and remove as many CONFIG_GK20A_VIDMEM preprocessor checks as possible
from the source code.
And lastly update a while-loop that iterated over an SGT to use the
new for_each construct for iterating over SGTs.
Currently this organization is not perfectly adhered to. More patches
will fix that.

Add an <nvgpu/errno.h> header file to explicitly include the -E* error
messages. Useful for header files with static inlines that return error
messages. In actual C code normally enough Linux/QNX headers bleed in
to get the error messages but header files with sparse includes do not
have this luxury.

sgl = sgl->next could happen twice.

Currently if channel has NEXT bit set while closing the channel we just print
an error and continue channel unbind sequence from TSG
But since channel with NEXT set is active killing it can potentially corrupt
the TSG context and cause unpredictable errors on remaining channels/TSG
Hence fix this by killing whole TSG context if channel being closed has
NEXT bit set
if gk20a_fifo_tsg_unbind_channel() API returns error, kill the TSG
otherwise continue with channel unbind sequence

Combine the VIDMEM and SYSMEM GMMU mapping paths into one
single function. With the proper nvgpu_sgt abstraction in
place the high level mapping code can treat these two types
of maps identically. The benefits of this are immediate: a
change to the mapping code will have much more testing
coverage - the same code runs on both vidmem and sysmem.
This also makes it easier to make changes to mapping code
since the changes will be testable no matter what type of
mem is being mapped.

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.
