Any PDE can allocate memory with a specific page size. That means memory
allocation with page size 4K and 64K will be realized by different PDEs
with page size (or PTE size) 4K and 64K respectively. To accomplish this
user vma is required to be pde aligned.
Currently, user vma is aligned by (big_page_size << 10) carried over
from when pde size was equivalent to (big_page_size << 10).
Modify user vma alignment check to use pde size.

Mapping of large buffers to GMMU end up needing many
pages for the PTE tables. Allocating these one by one
can end up being a performance bottleneck, particularly
in the virtualized case.
This is adding the following changes:
- As the TLB invalidation doesn't have access to mem_off,
allow top-level allocation by alloc_cache_direct().
- Define NVGPU_PD_CACHE_SIZE, the allocation size for a new slab
for the PD cache, effectively set to 64K bytes
- Use the PD cache for any allocation < NVGPU_PD_CACHE_SIZE
When freeing up cached entries, avoid prefetch errors by
invalidating the entry (memset to 0).
- Try to fall back to direct allocation of smaller chunk for
contiguous allocation failures.
- Unit test changes.

When a pbdma fault needs a channel teardown, do the recovery/teardown
process before acking the pbdma interrupt status back. Acking it causes
the hardware to proceed which could release fences too early before the
involved channel(s) have been found to be broken.
With these host copyengine interrupts, the teardown sequence is light
and proceeds even with the pbdma intr flag still set; there are no
engines to reset when these pbdma launch check interrupts happen. The
bad tsg is just disabled and the channels in it aborted.
A few unit tests are so heavily affected by this refactor that they
would need to be rewritten. They're not strictly needed at the moment,
so do only half of the rewrite: just delete them.

Fix up what unit tests can be easily fixed up. Stage everything else.
In short the unit test code is _incredibly_ fragile since it's designed
to hit every branch, positive and negative, in the code. However, the
result of that is unit tests that are painful to modify.
A lot of unit tests are also extremely opaque and rely on internal
nvgpu behavior. This patch will be updated with fixes as I make them.
Or, alternatively, it may be worth just temporarily disabling unit
tests on dev-main. We'll have a _lot_ of work for Orin that will
essentially gut the gr, host, and interrupt code. If we retain the
unit test code for this, it may end up being backgreaking.

Not sure if there's an actual bug or JIRA filed for this, but the
change here fixes a long standing bug in the MM code for unit tests.
Te GMMU programming code verifies that the CPU _physical_ address
programmed into the GMMU PDE0 is a valid Tegra SoC CPU physical
address. That means that it's not too large a value.
The POSIX imlementation of the nvgpu_mem related code used the CPU
virtual address as the "phys" address. Obviously, in userspace,
there's no access to physical addresses, so in some sense it's a
meaningless function. But the GMMU code does care, as described
above, about the format of the address.
The fix is simple enough: since the nvgpu_mem_get_addr() and
nvgpu_mem_get_phys_addr() values shouldn't actually be accessed by
the driver anyway (they could be vidmem addresses or IOVA addresses
in real life) ANDing them with 0xffffffff (e.g 32 bits) truncates
the potentially problematic CPU virtual address bits returned by
malloc() in the POSIX environment.
With this, a run of the unit test framework passes for me locally
on my Ubuntu 18 machine.
Also, clean up a few whitespace issues I noticed while I debugged
this and fix another long standing bug where the
NVGPU_DEFAULT_DBG_MASK was not being copied to g->log_mask during
gk20a struct init.

Currently the vGPU engine management rewrites a lot of the common
device agnostic engine management code.
With the new top HAL parsing one device at a time, it is now more
easily possible to tie the vGPU into the new common device framework
by implementing the top HAL but with the vGPU engine list backend.
This lets the vGPU inherit all the common engine and device
management code. By doing so the vGPU HAL need only implement a
trivial and simple HAL.
This also gets us a step closer to merging all of the CE init
code: logically it just iterates through all CE engines whatever
they may be. The only reason this differs between chips is because
of the swap from CE0-2 to LCEs in the Pascal generation. This could
be abstracted by the unit code easily enough.
Also, the pbdma_id for each engine has to be added to the device
struct. Eventually this was going to happen anyway, since the
device struct will soon replace the nvgpu_engine_info struct.
It's a little bit of an abuse but might be worth it long term. If
not, it should not be difficult to replace uses of dev->pbdma_id
with a proper lookup of PBDMA ID based on the device info.

The FIFO pbdma map is an array of bit maps that link PBDMAs to runlists.
This array allows other software to query what PBDMA(s) serves a given
runlist. The PBDMA map is read verbatim from an array of host registers.
These registers are stored in a kmalloc()'ed array.
This causes a problem for the device management code. The device
management initialization executes well before the rest of the FIFO
PBDMA initialization occurs. Thus, if the device management code
queries the PBDMA mapping for a given device/runlist, the mapping has
yet to be populated.
In the next patches in this series the engine management code is subsumed
into the device management code. In other words the device struct is
reused by the engine management and all host SW does is pull pointers to
the host managed devices from the device manager. This means that all
engine initialization that used to be done on top of the device
management needs to move to the device code.
So, long story short, the PBDMA map needs to be read from the registers
directly, instead of an array that gets allocated long after the device
code has run.
This patch removes the pbdma map array, deletes two HALs that managed
that, and instead provides a new HAL to query this map directly from
the registers so that the device code can use it.

Nvgpu does not support nested interrupts and as a result priv/pbus
interrupt do not reach cpu while other interrupts on intr_0 (stall)
tree are being processed. This issue is not specific to priv/pbus
but since pbus errors are critical, it is important to detect it
early on.
Below is the snippet from one of the failing logs where nvgpu
is doing recovery to process gr interrupt.
Right after GR engine is reset (PGRAPH of PMC_ENABLE), failing priv
accesses should have triggered pbus interrupt but it does not reach cpu
until gr interrupt is handled. Any interrupt that requires recovery will
take longer to finish isr as recovery is done as part of isr.
Also intr_0 (stall) interrupts are paused while stall interrupt is being
processed.
gm20b_gr_falcon_bind_instblk:147 [ERR] arbiter idle timeout, status: badf1020
gm20b_gr_falcon_wait_for_fecs_arb_idle:125 [ERR] arbiter idle timeout, fecs ctxsw status: 0xbadf1020
Fix to detect pbus intr while other stall interrupts are being processed
is to move pbus intr enable/disable/clear/handle to nonstall (intr_1)
tree. Configure pbus_intr_en_1 to route pbus to nostall tree.
Priv interrupts cannot be moved to nonstall (intr_1) tree due
to h/w not supporting this.
In Turing, moving pbus intr to nonstall is not feasible as mc_intr(1)
tree is deprecated. Add Turing specific stall intr handler hals with
original logic to route pbus intr to mc_intr(0).

Fix what unit tests can be easily fixed, but disable some others. It's
not clear why the MM related tests started failing - there's really zero
reason for this. The list of disable tests are primarily engine related

This adds a new device management unit in the common code responsible
for facilitating the parsing of the GPU top device list and providing
that info to other units in nvgpu.
The basic idea is to read this list once from HW and store it in a
set of lists corresponding to each device type (graphics, LCE, etc).
Many of the HALs in top can be deleted and instead implemented using
common code parsing the SW representation.
Every time the driver queries the device list it does so using a
device type and instance ID. This is common code. The HAL is responsible
for populating the device list in such a way that the driver can
query it in a chip agnostic manner.
Also delete some of the unit tests for functions that no longer
exist. This code will require new unit tests in time; those should be
quite simple to write once unit testing is needed.
