| |
| skiboot 5.9.7 was released on Friday December 22nd, 2017. It replaces |
| :ref:`skiboot-5.9.6` as the current stable release in the 5.9.x series. |
| |
| Over :ref:`skiboot-5.9.6`, we have two bug fixes, they are: |
| |
| - phb4: Change PCI MMIO timers |
| |
| Currently we have a mismatch between the NCU and PCI timers for MMIO |
| accesses. The PCI timers must be lower than the NCU timers otherwise |
| it may cause checkstops. |
| |
| This changes PCI timeouts controlled by skiboot to 33-50ms. It should |
| be forwards and backwards compatible with expected hostboot changes to |
| the NCU timer. |
| - p8-i2c: Limit number of retry attempts |
| |
| Currently we will attempt to start an I2C transaction until it succeeds. |
| In the event that the OCC does not release the lock on an I2C bus this |
| results in an async token being held forever and the kernel thread that |
| started the transaction will block forever while waiting for an async |
| completion message. Fix this by limiting the number of attempts to |
| start the transaction. |
