2020-09-11hwrng: imx-rngc - add quality to use it as kernel entropy poolMarco Felsch1-0/+1
The RNGB can generate 2^20 words (1 word == 4 byte) of 'random' data after the seed pool was initialized. The pool needs to be reseeded if more words are required. The reseeding is done automatically since commit 3acd9ea9331c ("hwrng: imx-rngc - use automatic seeding"). We can't retrieve the TRNG values directly so we need a other way to get the quality level. We know that the PRNG uses 20.000 entropy samples from the TRNG to generate 2^20 words (1MiB) and the quality level is defined as (in bits of entropy per 1024 bits of input). So the quality level can be calculated by: 20.000 * 1024 ------------- = ~ 19.5 2^20 Signed-off-by: Marco Felsch <[email protected]> Signed-off-by: Herbert Xu <[email protected]>

2020-08-21hwrng: optee - fix wait use caseJorge Ramirez-Ortiz1-2/+2
The current code waits for data to be available before attempting a second read. However the second read would not be executed as the while loop will exit. This fix does not wait if all data has been read (skips the call to msleep(0)) and reads a second time if partial data was retrieved on the first read. Worth noticing that since msleep(0) schedules a one jiffy timeout is better to skip such a call.
