PowerPC provides HW compression with NX coprocessor. This feature
is available on both PowerNV and PowerVM and included in Linux.
Since each powerpc chip has one NX coprocessor, the VAS introduces
the concept of windows / credits to manage access to this hardware
resource. On powerVM, these limit
Hi,
This patchset enables MOVE_PMD/MOVE_PUD support on power. This requires
the platform to support updating higher-level page tables without
updating page table entries. This also needs to invalidate the Page Walk
Cache on architecture supporting the same.
Changes from v3:
* Fix build error repo
Power9 processor supports Virtual Accelerator Switchboard (VAS) which
allows kernel and userspace to send compression requests to Nest
Accelerator (NX) directly. The NX unit comprises of 2 842 compression
engines and 1 GZIP engine. Linux kernel already has 842 compression
support on kernel. This
This is a repost of patch series from Peter with the arch specific changes
except ppc64 dropped.
ppc64 changes are added here because we are redoing the patch series on top of
ppc64 changes. This makes it
easy to backport these changes. Only the first 2 patches need to be backported
to stable.
Hi all,
Here is v4, with only a fix for a warning when CONFIG_IOV isn't defined.
Cover letter:
This patch set adds support for EEH recovery of hot plugged devices on pSeries
machines. Specifically, devices discovered by PCI rescanning using
/sys/bus/pci/rescan, which includes devices hotplugged

The purpose of this serie is to activate CONFIG_THREAD_INFO_IN_TASK which
moves the thread_info into task_struct.
Moving thread_info into task_struct has the following advantages:
- It protects thread_info from corruption in the case of stack
overflows.
- Its address is harder to determine if stac
This series addresses a couple of issues I have with building dts files.
First, the ability to build all the dts files in the tree. This has been
supported on most arches for some time with powerpc being the main
exception. The reason powerpc wasn't supported was it needed a change
in the location

These patches enable RX mappings of kernel text.
rodata is mapped RX as well as a trade-off, there
are more details in the patch description
As a prerequisite for R/O text, patch_instruction

The TPM PCRs are only reset on a hard reboot. In order to validate a
TPM's quote after a soft reboot (eg. kexec -e), the IMA measurement list
of the running kernel must be saved and then restored on the subsequent
boot, possibly of a different architecture.

Hello,
Note: We are currently discussing whether we need a new syscall so that
userspace can provide a custom device tree for the new kernel. Even if
that ends up being the way forward, it would affect only patches 7 and 8,
and even in those patches a significant part of the code would stay

Major changes since v3:
* the graph tracer works now.
It turned out the stack frame it tried to manipulate does not
exist at that point.
* changes only needed in order to support -mprofile-kernel are now
in a separate patch, prepended.
* Kconfig cleanup so this is only selectable
Whenever an interrupt is received for opal the linux kernel gets a
bitfield indicating certain events that have occurred and need handling
by the various device drivers. Currently this is handled using a
notifier interface where we call every device driver that has
registered to receive opal events
On PowerPC, when CPUs enter certain deep idle states, the local timers stop and
the
time base could go out of sync with the rest of the cores in the system.
This patchset adds support to wake up CPUs in such idle states by broadcasting
IPIs to them at their next timer events. We refer to these IP
