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.
