* [PATCH v4 1/4] ocxl: Rename struct link to ocxl_link
From: Alastair D'Silva @ 2019-03-25 5:34 UTC (permalink / raw)
To: alastair

In-Reply-To: <20190325053456.14599-1-alastair@au1.ibm.com>
From: Alastair D'Silva <alastair@d-silva.org>
The term 'link' is ambiguous (especially when the struct is used for a
list), so rename it for clarity.

* [PATCH v4 0/4] ocxl: OpenCAPI Cleanup

In-Reply-To: <20190320053448.2098-1-alastair@au1.ibm.com>
From: Alastair D'Silva <alastair@d-silva.org>
Some minor cleanups for the OpenCAPI driver as a prerequisite
for an ocxl driver refactoring to allow the driver core to
be utilised by external drivers.
Changelog:
V4:
- Drop printf format changes as they omit the format indicator for '0'
V3:
- Add missed header in 'ocxl: Remove some unused exported symbols'.
This addresses the introduced sparse warnings
V2:
- remove intermediate assignment of 'link' var in
'Rename struct link to ocxl_link'
- Don't shift definition of ocxl_context_attach in
'Remove some unused exported symbols'
Alastair D'Silva (4):
ocxl: Rename struct link to ocxl_link
ocxl: read_pasid never returns an error, so make it void
ocxl: Remove superfluous 'extern' from headers
ocxl: Remove some unused exported symbols

Um.. I'm not sure what you mean by this. As far as I'm concerned
there is always a guest-visible (paravirtualized) IOMMU, and that will
be backed onto the host IOMMU when necessary.
[Actually there is an IOMMU bypass hack that's used by the guest
firmware, but I don't think we want to expose that]

I assume that CONFIG_SPARSEMEM is the default for a good reason.
What I don't know is how strong that reason is (I am not a Power expert
at all). Looking a bit further, it seems to be related to CONFIG_NUMA
in that you can enable CONFIG_FLATMEM if and only if that's disabled.
So I suppose the configuration you used works for non-NUMA systems.
Anyway, does the patch I sent work for you?
Ben.

* Regression in 5.1.0-rc2: PowerBook G4 Aluminum fails to boot - bisected to commit 0df977eafc792
From: Larry Finger @ 2019-03-25 0:49 UTC (permalink / raw)
To: Christophe Leroy, Michael Ellerman, Benjamin Herrenschmidt,

A build of kernel 5.1.0-rc2 resulted in a failure to boot on my PowerBook G4
Aluminum. The bootstrap loads the initial kernel and issues the appropriate
start, but the machine hangs at that point.
The problem does not depend on the choice of PPC32 processor type. This machine
has a 7447A according to /proc/cpuinfo.
The problem was bisected to the following:
commit 0df977eafc792a5365a7f81d8d5920132e03afad
Author: Christophe Leroy <christophe.leroy@c-s.fr>
Date: Thu Feb 21 10:37:54 2019 +0000
powerpc/6xx: Don't use SPRN_SPRG2 for storing stack pointer while in RTAS
When calling RTAS, the stack pointer is stored in SPRN_SPRG2
in order to be able to restore it in case of machine check in RTAS.
As machine check is not a perfomance critical path, this patch
frees SPRN_SPRG2 by using a field in thread struct instead.
Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>
Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
I reverted this patch and found that the system began execution, and then
failed, likely due to the reassignment of SPRN_SPRG2.
I had found this problem with 5.1.0-rc1, but -rc2 was out by the time I finished
the bisection. Unfortunately, none of the changes in -rc2 fixed the problem.
Attached is the .config that I used.
Thanks,
Larry

Presumably you have CONFIG_PPC_BOOK3S_64 enabled and CONFIG_SPARSEMEM
disabled? Was this configuration actually usable?
I think this would fix the build failure:

but whether the result will actually *work*, I don't know.

For example, one of the benefits is to signal to host that driver does
not expect ability to access all memory. If it does, host can
fail initialization gracefully.

I presume legacy guests don't use encrypted memory so why do we

Well it's not just the reality, virt setups need something that
emulated IOMMUs don't provide. That is not uncommon, e.g.
intel's VTD has a "cache mode" field which AFAIK is only used for virt.

Hey Steve,
Here's a diff of output from 'make V=1 kernel/trace/trace_selftest_dynamic.o'
with stock v5.0 vs. v5.0 and that commit reverted. The part that I
think is interesting is where it decides to invoke recordmcount.pl
I can send or pastebin the entire output from make if that is easier to
read.

But you see it running the script if you remove that commit? Do you
happen to see -mrecord-mcount at all in a V=1 make?

* ppc64le: ftrace self-tests and $(CC_FLAGS_FTRACE) broken?
From: Joe Lawrence @ 2019-03-23 13:19 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Nicholas Piggin, Steven Rostedt
Hi Steve, Nicholas,
I stumbled across this while working on livepatch self-tests, which like
the ftrace self-tests, specify $(CC_FLAGS_FTRACE) to ensure that target
functions are indeed trace-able.
On ppc64le, v5.0 fails the self-tests on my machine:
% gcc --version
gcc (GCC) 8.2.1 20180905 (Red Hat 8.2.1-3)
% git checkout v5.0
% grep FTRACE_SELFTEST .config
CONFIG_FTRACE_SELFTEST=y
After building the kernel, I noticed no mcount sections and of course
the self-tests fail as it can't hook functions:
% readelf --sections kernel/trace/trace_selftest_dynamic.o | grep mcount
(nothing)

[ 126.390822] Failed to enable function tracer for event tests
I git bisected to 6977f95e63b9 ("powerpc: avoid -mno-sched-epilog on GCC
4.9 and newer"). Reverting this change and rebuilding, I could see the
mcount sections once again:
% readelf --sections kernel/trace/trace_selftest_dynamic.o | grep mcount
[ 3] __mcount_loc PROGBITS 0000000000000000 00000060
[ 4] .rela__mcount_loc RELA 0000000000000000 000258c8
Reboot and the self-test now passes.
Perhaps this is gcc version specific? I didn't see any other reports,
so maybe its specific to my config. If I run make V=1, I can see that
gcc is called with '-pg -mprofile-kernel', but then the record_mcount
script is skipped. Any ideas?

The arch fixups can be done regardless of the Kconfig change as far as
they are done before.
I guess it would then be easier to manage and review with a series of
small patches addressing each arch independently

Wouldn't it be useful to activate -Winline gcc warning to ease finding
out problematic usage of inline keyword ?

Thank you very much.
This problem existed before this commit (a8db8cf0d894).
and the SmPL we used is:
https://lkml.org/lkml/2019/3/14/880
We are still improving this SmPL, and it is somewhat different from the script
used by b1725c9319aa ("[POWERPC] arch/powerpc/sysdev: Add missing of_node_put").

OK.
Thank you.

* [PATCH 2/2] pci: rpaphp: get/put device node reference during slot alloc/dealloc
From: Tyrel Datwyler @ 2019-03-22 18:27 UTC (permalink / raw)

When allocating the slot structure we store a pointer to the associated
device_node. We really should be incrementing the reference count, so
add an of_node_get() during slot alloc and an of_node_put() during slot
dealloc.

* [PATCH 1/2] pci: rpadlpar: fix leaked device_node references in add/remove paths
From: Tyrel Datwyler @ 2019-03-22 18:27 UTC (permalink / raw)
To: bhelgaas; +Cc: linux-pci, linuxppc-dev, linux-kernel, Tyrel Datwyler
The find_dlpar_node() helper returns a device node with its reference
incremented. Both the add and remove paths use this helper for find the
appropriate node, but fail to release the reference when done.
Annotate the find_dlpar_node() helper with a comment about the incremented
reference count, and call of_node_put() on the obtained device_node in the
add and remove paths. Also, fixup a reference leak in the find_vio_slot()
helper where we fail to call of_node_put() on the vdevice node after we
iterate over its children.

I don't see that we can presume the user's intentions. This sounds
like we're putting the kernel into the position of deciding policy.

Is a user really indicating "I don't care about isolation" by placing
groups within the same container or just taking advantage of a shared
IOMMU context? Again, we're presuming a policy decision that's never
been defined in the API. It is possible to have both isolation and
performance, for instance ACS includes a direct translated p2p feature
that allows translated requests a direct path between devices, at least
on the PCIe fabric (where supported by hardware).

pci=option[,option...] [PCI] various PCI subsystem options.
Some options herein operate on a specific device
or a set of devices (<pci_dev>). These are
specified in one of the following formats:
[<domain>:]<bus>:<dev>.<func>[/<dev>.<func>]*
pci:<vendor>:<device>[:<subvendor>:<subdevice>]
...
disable_acs_redir=<pci_dev>[; ...]
Specify one or more PCI devices (in the format
specified above) separated by semicolons.
Each device specified will have the PCI ACS
redirect capabilities forced off which will
allow P2P traffic between devices through
bridges without forcing it upstream. Note:
this removes isolation between devices and
may put more devices in an IOMMU group.
AIUI, GPU and RDMA were primary use cases for this. As noted, IOMMU
groups take this into account since it's done at boot time and static,
we're simply disabling isolation switches that would have otherwise
been enabled at points in the topology (specifically enabling p2p as
much as possible), and the IOMMU group grows to match.
The NVLink problem is rather the opposite of this, rather than simply
disabling isolation for a sub-hierarchy and growing the IOMMU group, we
need to enable isolation and then actively, and repeatedly maintain
that configuration as it represents a finer granularity isolation
promise to the system. And of course we're trying to manage the
isolation of an interconnect for which we have no visibility.

The IOMMU driver is ultimately responsible for deciding the isolation,
but we have shared code that understands the PCI/e topology. That code
looks at the actual, current ACS settings to decide the highest point
in the topology where we might have p2p.

The iommu-core is incorporating more group-aware support, I believe
default domains are group based and we might have per group reserved
ranges, I'm not sure about that.

It might be a control point, yes, but I don't see that we can presume
it. If we were to automatically enable redirection within a container,
we could wreak havoc on the IOVA space for the user. ACS also
theoretically provides a hardware path to enable this via direct
translated p2p as well.

So it's therefore OK to intentionally pollute the container IOVA
space? I believe we'd like to think that hardware is headed towards
being more isolation-aware and will evolve to the point where we have
typically singleton group. Perhaps we'll also evolve to supporting ACS
direct translated p2p so that we have both a pristine IOVA space and
direct routes between devices. There are current issues with
non-singleton groups that userspace doesn't handle (see "fumble
through" comment above), but I'm not willing to say "this is
userspace's problem anyway, therefore it's ok it make it worse".

What is the value of this idea of potential isolation? Any device
might be considered potentially isolated, simply disable all the
devices around it. So now we have a "potentially isolated" group at
each device. What have we accomplished? How do we build that into a
user interface? Who decides where the actual isolation lines are
drawn? Not that it didn't happen, but I don't recall this design idea
and I don't see how it's practical.

Renaming everything doesn't help. AFAIK, there's nothing in vfio that
prevents groups from being dynamic (changing them while in use might be
unkind though), but they must be isolated from other groups. We can't
move the line where we have isolation to anything above the group.
Groups are currently not dynamic because "it's hard" (tm), but
obviously it can be done with device removal and rediscovery.

As above, groups are the unit of userspace ownership and therefore must
be isolated.

Groups must be isolated in the vfio API. What happens underneath a
group might be fungible, but the exposed group must be isolated.

Looks good modulo potential __get_user_pages_fast() suggestion.
