The latency tracking is done with ranges of bucket arrays.
The bucket for any given I/O is determined solely by TSC
deltas - any translation to microseconds is only done after
the test is finished and statistics are printed.
Each range has a number of buckets determined by a
NUM_BUCKETS_PER_RANGE value which is currently set to 128.
The buckets in ranges 0 and 1 each map to one specific TSC
delta. The buckets in subsequent ranges each map to twice
as many TSC deltas as buckets in the previous range:
Range 0: 1 TSC each - 128 buckets cover deltas 0 to 127
Range 1: 1 TSC each - 128 buckets cover deltas 128 to 255
Range 2: 2 TSC each - 128 buckets cover deltas 256 to 511
Range 3: 4 TSC each - 128 buckets cover deltas 512 to 1023
Range 4: 8 TSC each - 128 buckets cover deltas 1024 to 2047
Range 5: 16 TSC each - 128 buckets cover deltas 2048 to 4095
etc.
While here, change some variable names and usage
messages to differentiate between the existing latency
tracking via vendor-specific NVMe log pages on Intel
NVMe SSDs, and the newly added latency tracking done
in software.

Core dumps stop working if the path is longer than 64 bytes.
Use readlink to shorten some of the very long relative paths.

It has been discovered that some devices require
a very small delay before writing CC.EN to 1 after
CSTS.RDY goes to 0.

In the cache_append_no_cache test case, we need to
sync the file first, before calling cache_free_buffers().
Otherwise the buffers do not really get freed since they
contain dirty data.
This fixes a couple of memory leak bugs detected with
CONFIG_ASAN=y.

This parameter is not actually used by the unit
tests using the bdev, but setting it to a non-zero
value silences a couple of static analysis errors.

Negative queue depths, I/O sizes or time durations do
not make sense, so exit() if user input contains any of
those cases.

This is the initial commit for "blobfs", a lightweight
filesystem built on top of the SPDK blobstore.
Also included in this patch:
1) a shim for using SPDK bdevs as the backing store for
SPDK blobstore/blobfs
2) documentation for using blobfs as the storage engine
with RocksDB
3) scripts for running a set of workloads and collecting
profiling data with RocksDB and blobfs
See doc/blobfs/getting_started.md included in this commit
for more details on blobfs, including some of the current
limitations.

A few instances of DPDK_INC were added after the env library abstraction
was introduced; replace them with the correct ENV_CFLAGS variable
defined by env.mk.

This is the initial commit for the "blobstore", a lightweight,
highly parallel, persistent, power-fail safe block allocator.
Documentation will be added in future patches.

After checking the code, aerl in our session is 0,
so there will be only 1 AER. So currently,
we will only handle 1 AER case.
When the AER event is triggered by real NVMe device owned
by the subsystem, it notifies all sessions belonging to
the subsystem.

vtophys_get_paddr() and vtophys_get_dpdk_paddr() are doing similar
things; combine them into one function that works for all DPDK
memory addresses.
Part of the vtophys test is temporarily disabled until the next commit,
which will register all DPDK memory at startup and stop lookiing up
addresses at runtime.
