skiboot-5.4.1
|
|
=============
|
|
|
|
skiboot-5.4.1 was released on Tuesday November 29th 2016. It replaces
|
|
:ref:`skiboot-5.4.0` as the current stable release.
|
|
|
|
Over :ref:`skiboot-5.4.0`, we have a few changes:
|
|
|
|
- Nuvoton i2c TPM driver: bug fixes and improvements, especially around
|
|
timeouts and error handling.
|
|
- Limit number of "Poller recursion detected" errors to display.
|
|
In some error conditions, we could spiral out of control on this
|
|
and spend all of our time printing the exact same backtrace.
|
|
- slw: do SLW timer testing while holding xscom lock.
|
|
In some situations without this, it could take long enough to get
|
|
the xscom lock that the 1ms timeout would expire and we'd falsely
|
|
think the SLW timer didn't work when in fact it did.
|
|
- p8i2c: Use calculated poll_interval when booting OPAL.
|
|
Otherwise we'd default to 2seconds (TIMER_POLL) during boot on
|
|
chips with a functional i2c interrupt, leading to slow i2c
|
|
during boot (or hitting timeouts instead).
|
|
- i2c: More efficiently run TPM I2C operations during boot, avoiding hitting
|
|
timeouts
|
|
- fsp: Don't recurse pollers in ibm_fsp_terminate
