skiboot-5.6.0-rc2
|
|||
|
|
=================
|
|||
|
|
|
|||
|
|
skiboot-5.6.0-rc2 was released on Friday May 19th 2017. It is the second
|
|||
|
|
release candidate of skiboot 5.6, which will become the new stable release
|
|||
|
|
of skiboot following the 5.5 release, first released April 7th 2017.
|
|||
|
|
|
|||
|
|
skiboot-5.6.0-rc2 contains all bug fixes as of :ref:`skiboot-5.4.4`
|
|||
|
|
and :ref:`skiboot-5.1.19` (the currently maintained stable releases). We
|
|||
|
|
do not currently expect to do any 5.5.x stable releases.
|
|||
|
|
|
|||
|
|
For how the skiboot stable releases work, see :ref:`stable-rules` for details.
|
|||
|
|
|
|||
|
|
The current plan is to cut the final 5.6.0 by May 22nd, with skiboot 5.6.0
|
|||
|
|
being for all POWER8 and POWER9 platforms in op-build v1.17 (Due May 24th).
|
|||
|
|
This is a short cycle as this release is mainly targetted towards POWER9
|
|||
|
|
bringup efforts.
|
|||
|
|
|
|||
|
|
With skiboot 5.6.0, we are moving to a regular six week release cycle,
|
|||
|
|
similar to op-build, but slightly offset to allow for a short stabilisation
|
|||
|
|
period. Expected release dates and contents are tracked using GitHub milestone
|
|||
|
|
and issues: https://github.com/open-power/skiboot/milestones
|
|||
|
|
|
|||
|
|
Over :ref:`skiboot-5.6.0-rc1`, we have the following changes:
|
|||
|
|
|
|||
|
|
- hw/i2c: Fix early lock drop
|
|||
|
|
|
|||
|
|
When interacting with an I2C master the p8-i2c driver (common to p9)
|
|||
|
|
aquires a per-master lock which it holds for the duration of it's
|
|||
|
|
interaction with the master. Unfortunately, when
|
|||
|
|
p8_i2c_check_initial_status() detects that the master is busy with
|
|||
|
|
another transaction it drops the lock and returns OPAL_BUSY. This is
|
|||
|
|
contrary to the driver's locking strategy which requires that the
|
|||
|
|
caller aquire and drop the lock. This leads to a crash due to the
|
|||
|
|
double unlock(), which skiboot treats as fatal.
|
|||
|
|
|
|||
|
|
- mambo: Add skiboot/linux symbol lookup
|
|||
|
|
|
|||
|
|
Adds the skisym and linsym commands which can be used to find the
|
|||
|
|
address of a Linux or Skiboot symbol. To function this requires
|
|||
|
|
the user to provide the SKIBOOT_MAP and VMLINUX_MAP environmental
|
|||
|
|
variables which indicate which skiboot.map and System.map files
|
|||
|
|
should be used.
|
|||
|
|
|
|||
|
|
Examples:
|
|||
|
|
|
|||
|
|
- Look up a symbol address: ::
|
|||
|
|
|
|||
|
|
systemsim % skisym .load_and_boot_kernel
|
|||
|
|
0x0000000030013a08
|
|||
|
|
|
|||
|
|
- Set a breakpoint there: ::
|
|||
|
|
|
|||
|
|
systemsim % b [skisym .load_and_boot_kernel]
|
|||
|
|
breakpoint set at [0:0]: 0x0000000030013a08 (0x0000000030013A08) Enc:0x7D800026 : mfcr r12
|
|||
|
|
|
|||
|
|
|
|||
|
|
- libstb: Fix build in OpenSSL 1.1
|
|||
|
|
|
|||
|
|
The build failure was as follows: ::
|
|||
|
|
|
|||
|
|

|||
|
|
