.. _skiboot-5.4.7: | ||
|
||
============= | ||
skiboot-5.4.7 | ||
============= | ||
|
||
skiboot-5.4.7 was released on Tuesday September 19th, 2017. It replaces | ||
:ref:`skiboot-5.4.6` as the current stable release in the 5.4.x series. | ||
|
||
Over :ref:`skiboot-5.4.6`, we have two backported bug fixes for FSP platforms: | ||
|
||
- FSP: Add check to detect FSP Reset/Reload inside fsp_sync_msg() | ||
|
||
During FSP Reset/Reload we move outstanding MBOX messages from msgq to | ||
rr_queue including inflight message (fsp_reset_cmdclass()). But we are not | ||
resetting inflight message state. | ||
|
||
In extreme corner case where we sent message to FSP via fsp_sync_msg() path | ||
and FSP Reset/Reload happens before getting respose from FSP, then we will | ||
endup waiting in fsp_sync_msg() until everything becomes normal. | ||
|
||
This patch adds fsp_in_rr() check to fsp_sync_msg() and return error to | ||
caller if FSP is in R/R. | ||
|
||
- platforms/ibm-fsp/firenze: Fix PCI slot power-off pattern | ||
|
||
When powering off the PCI slot, the corresponding bits should | ||
be set to 0bxx00xx00 instead of 0bxx11xx11. Otherwise, the | ||
specified PCI slot can't be put into power-off state. Fortunately, | ||
it didn't introduce any side-effects so far. |
