The closer the cache is to the CPU 1289 the less variations are measured and thus the less entropy is 1290 obtained. Thus, if the memory size fits into the L1 cache, the 1291 obtained entropy is less than if the memory size fits within 1292 L1 + L2, which in turn is less if the memory fits into 1293 L1 + L2 + L3. Thus, by selecting a different memory size, 1294 the entropy rate produced by the Jitter RNG can be modified. 1295 1296 config CRYPTO_JITTERENTROPY_MEMSIZE_2 1297 bool "2048 Bytes (default)" 1298 1299 config CRYPTO_JITTERENTROPY_MEMSIZE_128 1300 bool "128 kBytes" 1301 1302 config CRYPTO_JITTERENTROPY_MEMSIZE_1024 1303 bool "1024 kBytes" 1304 1305 config CRYPTO_JITTERENTROPY_MEMSIZE_8192 1306 bool "8192 kBytes" 1307endchoice 1308 1309config CRYPTO_JITTERENTROPY_MEMORY_BLOCKS 1310 int 1311 default 64 if CRYPTO_JITTERENTROPY_MEMSIZE_2 1312 default 512 if CRYPTO_JITTERENTROPY_MEMSIZE_128 1313 default 1024 if CRYPTO_JITTERENTROPY_MEMSIZE_1024 1314 default 4096 if CRYPTO_JITTERENTROPY_MEMSIZE_8192 1315 1316config CRYPTO_JITTERENTROPY_MEMORY_BLOCKSIZE 1317 int 1318 default 32 if CRYPTO_JITTERENTROPY_MEMSIZE_2 1319 default 256 if CRYPTO_JITTERENTROPY_MEMSIZE_128 1320 default 1024 if CRYPTO_JITTERENTROPY_MEMSIZE_1024 1321 default 2048 if CRYPTO_JITTERENTROPY_MEMSIZE_8192 1322 1323config CRYPTO_JITTERENTROPY_OSR 1324 int "CPU Jitter RNG Oversampling Rate" 1325 range 1 15 1326 default 1 1327 help 1328 The Jitter RNG allows the specification of an oversampling rate (OSR). 1329 The Jitter RNG operation requires a fixed amount of timing 1330 measurements to produce one output block of random numbers. The 1331 OSR value is multiplied with the amount of timing measurements to 1332 generate one output block. Thus, the timing measurement is oversampled 1333 by the OSR factor. The oversampling allows the Jitter RNG to operate 1334 on hardware whose timers deliver limited amount of entropy (e.g. 1335 the timer is coarse) by setting the OSR to a higher value. The 1336 trade-off, however, is that the Jitter RNG now requires more time 1337 to generate random numbers. 1338 1339config CRYPTO_JITTERENTROPY_TESTINTERFACE 1340 bool "CPU Jitter RNG Test Interface" 1341 help 1342 The test interface allows a privileged process to capture 1343 the raw unconditioned high resolution time stamp noise that 1344 is collected by the Jitter RNG for statistical analysis. As 1345 this data is used at the same time to generate random bits, 1346 the Jitter RNG operates in an insecure mode as long as the 1347 recording is enabled. This interface therefore is only 1348 intended for testing purposes and is not suitable for 1349 production systems. 1350 1351 The raw noise data can be obtained using the jent_raw_hires 1352 debugfs file.
