For L2 HPT guests, the old hcall is expected to work after it adds
support for R=0 case?
The new hcall should be advertised via ibm,hypertas-functions only
for radix guests I suppose.

0day had one crash on the last round, I think Steve send a fix for that
last night and I'll go look at it.
That said, the last posting got 0 feedback, so either everybody is
really happy with it, or not interested. So let us know in the thread,
with some review feedback.
Once I get through enough of the inbox to actually find the fix and test
it, I'll also update the thread, and maybe threaten to merge it if
everybody stays silent :-)

The original implementation of relocation doesn't move the kernel's linear map
to the vmalloc region, and I also give the KASLR RFC patch [1] based on that.
In original, we relocate the kernel in the linear map region, we would
calculate a
random value first as the offset, then we move the kernel image to the
new target
address which is obtained by adding this offset to it's VA and PA.
It's enough for
randomizing the kernel, but it seems to me if we want to decouple the kernel's
linear mapping, the physical mapping of RAM and virtual mapping of RAM,
it might be good to move the kernel's mapping out from the linear region.
Even so, it is still an intrusive change. As far as I know, only arm64
does something
like that.

Using the 'extern' keyword on function declaration is pointless and
should be avoided in new patches. (checkpatch.pl --strict usually
complains about it).

generated a memory error to nvdimm bad range.

Introduce notification chain which lets know about uncorrected memory
errors(UE). This would help prospective users in pmem or nvdimm subsystem
to track bad blocks for better handling of persistent memory allocations.

The ioreadX() helpers have inconsistent interface. On some architectures
void *__iomem address argument is a pointer to const, on some not.
Implementations of ioreadX() do not modify the memory under the address
so they can be converted to a "const" version for const-safety and
consistency among architectures.

* [PATCH v3 0/4] iomap: Constify ioreadX() iomem argument

Cc: Krzysztof Kozlowski
Hi,
Multiple architectures are affected in the first patch and all further
patches depend on the first.
Maybe this could go in through Andrew Morton's tree?
Changes since v2
================
1. Drop all non-essential patches (cleanups),
2. Update also drivers/sh/clk/cpg.c .
Changes since v1
================
https://lore.kernel.org/lkml/1578415992-24054-1-git-send-email-krzk@kernel.org/
1. Constify also ioreadX_rep() and mmio_insX(),
2. Squash lib+alpha+powerpc+parisc+sh into one patch for bisectability,
3. Add acks and reviews,
4. Re-order patches so all optional driver changes are at the end.
Description
===========
The ioread8/16/32() and others have inconsistent interface among the
architectures: some taking address as const, some not.
It seems there is nothing really stopping all of them to take
pointer to const.
Patchset was only compile tested on affected architectures. No real
testing.
volatile
========
There is still interface inconsistency between architectures around
"volatile" qualifier:
- include/asm-generic/io.h:static inline u32 ioread32(const volatile void __iomem *addr)
- include/asm-generic/iomap.h:extern unsigned int ioread32(const void __iomem *);
This is still discussed and out of scope of this patchset.
Best regards,
Krzysztof

This is defined in patch 8 "powerpc/perf: Add support for outputting extended regs in perf intr_regs”,
which adds the base support for extended regs in powerpc. Current patch covers changes to support
It for power10.
`mask_var` is used to define `PERF_REG_EXTENDED_MASK` at run time.
`PERF_REG_EXTENDED_MASK` basically contains mask value of supported extended registers.
And since supported registers may differ between processor versions, we are defining this mask at runtime.
The #define is done in arch/powerpc/include/asm/perf_event_server.h ( in patch 8 ).
In the PMU driver init, we will set the respective mask value ( in the below code ). Hence it is extern
Sorry for the confusion here.
Thanks

* [PATCH v5 2/2] powerpc/hv-24x7: Add sysfs files inside hv-24x7 device to show cpumask
From: Kajol Jain @ 2020-07-09 5:18 UTC (permalink / raw)
To: linuxppc-dev, mpe; +Cc: nathanl, ego, maddy, kjain, suka, anju
In-Reply-To: <20200709051836.723765-1-kjain@linux.ibm.com>
Patch here adds a cpumask attr to hv_24x7 pmu along with ABI documentation.
Primary use to expose the cpumask is for the perf tool which has the
capability to parse the driver sysfs folder and understand the
cpumask file. Having cpumask file will reduce the number of perf command
line parameters (will avoid "-C" option in the perf tool
command line). It can also notify the user which is
the current cpu used to retrieve the counter data.

* [PATCH v5 0/2] Add cpu hotplug support for powerpc/perf/hv-24x7
From: Kajol Jain @ 2020-07-09 5:18 UTC (permalink / raw)
To: linuxppc-dev, mpe; +Cc: nathanl, ego, maddy, kjain, suka, anju
This patchset add cpu hotplug support for hv_24x7 driver by adding
online/offline cpu hotplug function. It also add sysfs file
"cpumask" to expose current online cpu that can be used for
hv_24x7 event count.
Changelog:
v4 -> v5
- Since we are making PMU fail incase hotplug init failed, hence
directly adding cpumask attr inside if_attrs rather then creating
new attribute_group as suggested by Madhavan Srinivasan.
v3 -> v4
- Make PMU initialization fail incase hotplug init failed. Rather then
just printing error msg.
- Did some nits changes like removing extra comment and initialising
target value part as suggested by Michael Ellerman
- Retained Reviewd-by tag because the changes were fixes to some nits.
- Incase we sequentially offline multiple cpus, taking cpumask_first() may
add some latency in that scenario.
So, I was trying to test benchmark in power9 lpar with 16 cpu,
by off-lining cpu 0-14
With cpumask_last: This is what I got.
real 0m2.812s
user 0m0.002s
sys 0m0.003s
With cpulast_any:
real 0m3.690s
user 0m0.002s
sys 0m0.062s
That's why I just went with cpumask_last thing.
v2 -> v3
- Corrected some of the typo mistakes and update commit message
as suggested by Gautham R Shenoy.
- Added Reviewed-by tag for the first patch in the patchset.
v1 -> v2
- Changed function to pick active cpu incase of offline
from "cpumask_any_but" to "cpumask_last", as
cpumask_any_but function pick very next online cpu and incase where
we are sequentially off-lining multiple cpus, "pmu_migrate_context"
can add extra latency.
- Suggested by: Gautham R Shenoy.
- Change documentation for cpumask and rather then hardcode the
initialization for cpumask_attr_group, add loop to get very first
NULL as suggested by Gautham R Shenoy.

In-Reply-To: <20200709051836.723765-1-kjain@linux.ibm.com>
Patch here adds cpu hotplug functions to hv_24x7 pmu.
A new cpuhp_state "CPUHP_AP_PERF_POWERPC_HV_24x7_ONLINE" enum
is added.
The online callback function updates the cpumask only if its
empty. As the primary intention of adding hotplug support
is to designate a CPU to make HCALL to collect the
counter data.
The offline function test and clear corresponding cpu in a cpumask
and update cpumask to any other active cpu.

What are we going to use when nested KVM supports HPT guests at L2?
L1 will need to do partition-scoped tlbies with R=0 via a hypercall,
but H_RPT_INVALIDATE says in its name that it only handles radix
page tables (i.e. R=1).

I know it's been a while, but I keep opening this up to review it and just
can't get over how ugly it is to put the kernel's linear map in the vmalloc
region.
I guess I don't understand why this is necessary at all. Specifically: why
can't we just relocate the kernel within the linear map? That would let the
bootloader put the kernel wherever it wants, modulo the physical memory size we
support. We'd need to handle the regions that are coupled to the kernel's
execution address, but we could just put them in an explicit memory region
which is what we should probably be doing anyway.

Well, that's not enough to make sure this doesn't happen -- it's just enough to
make sure it doesn't happen very quickily. That's the same boat we're already
in, though, so it's not like it's worse.

At a bare minimum this is going to make a mess of the 32-bit port, as
non-relocatable kernels are now going to get linked at 1GiB which is where user
code is supposed to live. That's an easy fix, though, as the 32-bit stuff
doesn't need any module address restrictions.
