| skiboot-5.1.19 |
| -------------- |
| |
| skiboot-5.1.19 was released on Monday 16th January 2017. |
| |
| skiboot-5.1.19 is the 20th stable release of 5.1, it follows skiboot-5.1.18 |
| (which was released 26th August 2016). |
| |
| This release contains a few minor bug fixes. |
| |
| Changes are: |
| |
| Generic: |
| |
| - Makefile: Disable stack protector due to gcc problems |
| - stack: Don't recurse into __stack_chk_fail |
| - Makefile: Use -ffixed-r13 |
| We did not find evidence of this ever being a problem, but this fix |
| is good and preventative. |
| - 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. |
| Limit it to 16 times, because 16 is a nice number. |
| |
| FSP based Systems: |
| |
| - fsp: Don't recurse pollers in ibm_fsp_terminate |
| If we were to terminate in a poller, we'd call op_display() which |
| called pollers which hit the recursive poller warning, which ended |
| in not much fun at all. |
| |
| PCI: |
| |
| - hw/phb3: set PHB retry state correctly when fresetting during a creset |
| - phb3: Lock the PHB on set_xive callbacks |
| Those are called by the interrupts core and thus skip the locking |
| implicit in the PCI opal calls. |
| - hw/{phb3, p7ioc}: Return success for freset on empty PHB |
| OPAL_CLOSED is returned when fundamental reset is issued on the |
| PHB who doesn't have subordinate devices (root port excluded). |
| The kernel raises an error message, which is unnecessary. This |
| returns OPAL_SUCCESS for this case to avoid the error message. |
| - hw/phb3: fix error handling in complete reset |
| During a complete reset, when we get a timeout waiting for pending |
| transaction in state PHB3_STATE_CRESET_WAIT_CQ, we mark the PHB as broken |
| and return OPAL_PARAMETER. |
| Change the return code to OPAL_HARDWARE which is way more sensible, and set |
| the state to PHB3_STATE_FENCED so that the kernel can retry the complete |
| reset. |
