Device tree aware platforms can make use of CMDLINE_EXTEND to extend the
kernel command line provided by the bootloader. This is particularly
useful to set parameters for built-in modules that would otherwise be
done at module insertion. Add support for this in the powerpc
architecture.
Hi,
may I also ask to provide ppc_clone3 symbol also for 32-bit powerpc? Otherwise
Michael's patch breaks build for me:
powerpc-e500v2-linux-gnuspe-ld: arch/powerpc/kernel/systbl.o: in function
`sys_call_table':
(.rodata+0x6cc): undefined reference to `ppc_clone3'

Each iteration of for_each_child_of_node puts the previous node, but
in the case of a return from the middle of the loop, there is no put,
thus causing a memory leak. Add an of_node_put before the return.
Issue found with Coccinelle.

In some cases initial bind of scm memory for an lpar can fail if
previously it wasn't released using a scm-unbind hcall. This situation
can arise due to panic of the previous kernel or forced lpar
fadump. In such cases the H_SCM_BIND_MEM return a H_OVERLAP error.
To mitigate such cases the patch
The new hcall named H_SCM_UNBIND_ALL has been introduce that can
unbind all or specific scm memory assigned to an lpar. This is
more efficient than using H_SCM_UNBIND_MEM as currently we don't
support partial unbind of scm memory.
Hence this patch proposes following changes to drc_pmem_unbind():
Update the hvcalls.h to include op-codes for new hcalls introduce to
manage SCM memory. Also update existing hcall definitions to reflect
current papr specification for SCM.
The removed hcall op-codes H_SCM_MEM_QUERY, H_SCM_BLOCK_CLEAR were
transient proposals and there support was never
This doc patch provides an initial description of the HCall op-codes
that are used by Linux kernel running as a guest operating
system (LPAR) on top of PowerVM or any other sPAPR compliant
hyper-visor (e.g qemu).
Apart from documenting the HCalls the doc-patch also provides a
rudimentary overview
Presently an error is returned in response to hcall H_SCM_BIND_MEM when a
new kernel boots on lpar via kexec. This prevents papr_scm from registering
drc memory regions with nvdimm. The error reported is of the form below:
"papr_scm ibm,persistent-memory:ibm,pmemory@4412: bind err: -68"

OK. Are we sure we're not doing anything stupid in that code to make it

The cpufreq core now takes the min/max frequency constraints via QoS
requests and the CPUFREQ_ADJUST notifier shall get removed later on.
Switch over to using the QoS request for maximum frequency constraint
for windfarm_cpufreq_clamp driver.

Hello,
Now that cpufreq core supports taking QoS requests for min/max cpu
frequencies, lets migrate rest of the users to using them instead of the
policy notifiers.
The CPUFREQ_NOTIFY and CPUFREQ_ADJUST events of the policy notifiers are
removed as a result, but we have to add
Convert existing messages, where appropriate, to use the eeh_edev_*
logging macros.
The only effect should be minor adjustments to the log messages, apart
from:
- A new message in pseries_eeh_probe() "Probing device" to match the
powernv case.
- The "Probing device" message in pnv_eeh_probe() is
On PowerNV and pSeries, devices currently acquire EEH support from
several different places: Boot-time devices from eeh_probe_devices()
and eeh_addr_cache_build(), Virtual Function devices from the pcibios
bus add device hooks and hot plugged devices from pci_hp_add_devices()
(with other platforms
Now that EEH support for all devices (on PowerNV and pSeries) is
provided by the pcibios bus add device hooks, eeh_probe_devices() and
eeh_addr_cache_build() are redundant and can be removed.
Move the EEH enabled message into it's own function so that it can be
called from multiple places.
Note
Hi all,
Here is v3, addressing feedback from v2 to do with debug logging.
It includes a new patch from Oliver O'Halloran (patch 7) and two additional
patches based on it. See those patches for details.
Cover letter:
This patch set adds support for EEH recovery of hot plugged devices on pSeries
The EEH_DEV_NO_HANDLER flag is used by the EEH system to prevent the
use of driver callbacks in drivers that have been bound part way
through the recovery process. This is necessary to prevent later stage
handlers from being called when the earlier stage handlers haven't,
which can be confusing
Also remove useless comment.
