+ prompt "CPU Jitter RNG Memory Size"
+ default CRYPTO_JITTERENTROPY_MEMSIZE_2
+ help
+ The Jitter RNG measures the execution time of memory accesses.
+ Multiple consecutive memory accesses are performed. If the memory
+ size fits into a cache (e.g. L1), only the memory access timing
+ to that cache is measured. The closer the cache is to the CPU
+ the less variations are measured and thus the less entropy is
+ obtained. Thus, if the memory size fits into the L1 cache, the
+ obtained entropy is less than if the memory size fits within
+ L1 + L2, which in turn is less if the memory fits into
+ L1 + L2 + L3. Thus, by selecting a different memory size,
+ the entropy rate produced by the Jitter RNG can be modified.

+ range 1 15
+ default 3
+ help
+ The Jitter RNG allows the specification of an oversampling rate (OSR).
+ The Jitter RNG operation requires a fixed amount of timing
+ measurements to produce one output block of random numbers. The
+ OSR value is multiplied with the amount of timing measurements to
+ generate one output block. Thus, the timing measurement is oversampled
+ by the OSR factor. The oversampling allows the Jitter RNG to operate
+ on hardware whose timers deliver limited amount of entropy (e.g.
+ the timer is coarse) by setting the OSR to a higher value. The
+ trade-off, however, is that the Jitter RNG now requires more time
+ to generate random numbers.
+
+config CRYPTO_JITTERENTROPY_TESTINTERFACE
+ bool "CPU Jitter RNG Test Interface"
+ help
+ The test interface allows a privileged process to capture
+ the raw unconditioned high resolution time stamp noise that
+ is collected by the Jitter RNG for statistical analysis. As
+ this data is used at the same time to generate random bits,
+ the Jitter RNG operates in an insecure mode as long as the
+ recording is enabled. This interface therefore is only
+ intended for testing purposes and is not suitable for
+ production systems.
+
+ The raw noise data can be obtained using the jent_raw_hires
+ debugfs file. Using the option
+ jitterentropy_testing.boot_raw_hires_test=1 the raw noise of
+ the first 1000 entropy events since boot can be sampled.
