skiboot-6.0.15
|
|
==============
|
|
|
|
skiboot 6.0.15 was released on Monday December 17th, 2018. It replaces
|
|
:ref:`skiboot-6.0.14` as the current stable release in the 6.0.x series.
|
|
|
|
It is recommended that 6.0.15 be used instead of any previous 6.0.x version
|
|
due to the bug fixes it contains.
|
|
|
|
Bug fixes included in this release are:
|
|
|
|
- i2c: Fix i2c request hang during opal init if timers are not checked
|
|
|
|
If an i2c request cannot go through the first time, because the bus is
|
|
found in error and need a reset or it's locked by the OCC for example,
|
|
the underlying i2c implementation is using timers to manage the
|
|
request. However during opal init, opal pollers may not be called, it
|
|
depends in the context in which the i2c request is made. If the
|
|
pollers are not called, the timers are not checked and we can end up
|
|
with an i2c request which will not move foward and skiboot hangs.
|
|
|
|
Fix it by explicitly checking the timers if we are waiting for an i2c
|
|
request to complete and it seems to be taking a while.

|
- opal-prd: hservice: Enable hservice->wakeup() in BMC
|
|
|
|
This patch enables HBRT to use HYP special wakeup register in openBMC
|
|
which until now was only used in FSP based machines.
|
|
|
|
This patch also adds a capability check for opal-prd so that HBRT can
|
|
decide if the host special wakeup register can be used.

|
- npu2: Advertise correct TCE page size
|
|
|
|
The P9 NPU workbook says that only 4K/64K/16M/256M page size are supported
|
|
and in fact npu2_map_pe_dma_window() supports just these but in absence of
|
|
the "ibm,supported-tce-sizes" property Linux assumes the default P9 PHB4
|
|
page sizes - 4K/64K/2M/1G - so when Linux tries 2M/1G TCEs, we get lots of
|
|
"Unexpected TCE size" from npu2_tce_kill().
|
|
|
|
This advertises TCE page sizes so Linux could handle it correctly, i.e.
|
|
fall back to 4K/64K TCEs.
