Some GFX9 devices will drop commands if ring buffer submission is less
than 64 DWORDs. Pad submission with a NOP head an trailing null
DWORDs in this case.

We don't need to keep track of specific blit engines in gang for

In ASAN builds, the compiler used is clang. The initialization of
variable sized array using assignment operator is causing compilation
failure in ASAN builds. Used memset to fix the same.

When oversubscribing SDMA gangs, a circular deadlock can occur since
gang enqueue is staggered with respect to SDMA engine leader based
on source to destination.
As a result, an enqueued leader may be waiting on a gang item that is
waiting on another enqueued leader or gang item and so on.
To prevent this, first lock the submission to ensure dma status query
and submissions are atomic. Once this is in place, be more stringent
with ganging in that all SDMA engines must be available in order to gang.
Finally, re-enable SDMA ganging by default.

xGMI for compute partitioning in non-SPX modes does not have

Fix it to at most 2 since each partition is either bounded
by the number of xGMI links or the number of available
SDMA contexts.

Use all available SDMA engines capped by xGMI bandwith for
all D2D copies within a hive.
By default, set the latency boundary copy size as 4KB and below.
Any copy size in within this boundary will not gang.
Avoid oversubscribing engines by not ganging on engines with
pending non-ganged work.
An enviroment variable HSA_ENABLE_SDMA_GANG has been provided
to override default ganging behaviour.

For xnack off, skip SVM evict tests if memory allocation size is larger
than 15/16 total system memory, because the test may fail to allocate
CWSR svm range to create queue after allocating test memory.
Limit eviction size from total VRAM size to 1/2 total VRAM size,
because for 192GB VRAM, evict 192GB may takes more than 120 seconds
and cause test timeout failed.
