Subject: [PATCH] tpm: use tpm_msleep() value as max delay
|
|
|
|
Currently, tpm_msleep() uses delay_msec as the minimum value in
|
|
usleep_range. However, that is the maximum time we want to wait.
|
|
The function is modified to use the delay_msec as the maximum
|
|
value, not the minimum value.
|
|
|
|
After this change, performance on a TPM 1.2 with an 8 byte
|
|
burstcount for 1000 extends improved from ~9sec to ~8sec.
