* [PATCH 02/18] powerpc/{powernv,pseries}: Move PHB discovery
From: Oliver O'Halloran @ 2020-11-03 4:35 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Oliver O'Halloran
In-Reply-To: <20201103043523.916109-1-oohall@gmail.com>
Make powernv and pseries use ppc_mc.discover_phbs. These two platforms need
to be done together because they both depends on pci_dn's being created
from the DT. The pci_dn contains a pointer to the relevant pci_controller
so they need to be created after the pci_controller structures are
available, but before and before PCI devices are scanned. Currently this
ordering is provided by initcalls and the sequence is:
1. PHBs are discovered (setup_arch) (early boot, pre-initcalls)
2. pci_dn are created from the unflattended DT (core initcall)
3. PHBs are scanned pcibios_init() (subsys initcall)
The new ppc_md.discover_phbs() function is also a core_initcall so we can't
guarantee ordering between the creations of pci_controllers and the
creation of pci_dn's which require a pci_controller. We could use the
postcore, or core_sync initcall levels, but it's cleaner to just move the
pci_dn setup into the per-PHB inits which occur inside of .discover_phb()
for these platforms. This brings the boot-time path in line with the PHB
hotplug path that is used for pseries DLPAR operations too.

* [PATCH 01/18] powerpc/pci: Add ppc_md.discover_phbs()
From: Oliver O'Halloran @ 2020-11-03 4:35 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Paul Mackerras, Oliver O'Halloran
On many powerpc platforms the discovery and initalisation of
pci_controllers (PHBs) happens inside of setup_arch(). This is very early
in boot (pre-initcalls) and means that we're initialising the PHB long
before many basic kernel services (slab allocator, debugfs, a real ioremap)
are available.
On PowerNV this causes an additional problem since we map the PHB registers
with ioremap(). As of commit d538aadc2718 ("powerpc/ioremap: warn on early
use of ioremap()") a warning is printed because we're using the "incorrect"
API to setup and MMIO mapping in searly boot. The kernel does provide
early_ioremap(), but that is not intended to create long-lived MMIO
mappings and a seperate warning is printed by generic code if
early_ioremap() mappings are "leaked."
This is all fixable with dumb hacks like using early_ioremap() to setup
the initial mapping then replacing it with a real ioremap later on in
boot, but it does raise the question: Why the hell are we setting up the
PHB's this early in boot?
The old and wise claim it's due to "hysterical rasins." Aside from amused
grapes there doesn't appear to be any real reason to maintain the current
behaviour. Already most of the newer embedded platforms perform PHB
discovery in an arch_initcall and between the end of setup_arch() and the
start of initcalls none of the generic kernel code does anything PCI
related. On powerpc scanning PHBs occurs in a subsys_initcall so it should
be possible to move the PHB discovery to a core, postcore or arch initcall.
This patch adds the ppc_md.discover_phbs hook and a core_initcall stub that
calls it. The core_initcalls are the earliest to be called so this will
any possibly issues with dependency between initcalls. This isn't just an
academic issue either since on pseries and PowerNV EEH init occurs in an
arch_initcall and depends on the pci_controllers being available, similarly
the creation of pci_dns occurs at core_initcall_sync (i.e. between core and
postcore initcalls). These problems need to be addressed seperately.

* [PATCH AUTOSEL 5.4 15/24] scsi: ibmvscsi: Fix potential race after loss of transport
From: Sasha Levin @ 2020-11-03 1:19 UTC (permalink / raw)
To: linux-kernel, stable
Cc: Sasha Levin, Tyrel Datwyler, linuxppc-dev, linux-scsi,

In-Reply-To: <20201103012007.183429-1-sashal@kernel.org>
From: Tyrel Datwyler <tyreld@linux.ibm.com>
[ Upstream commit 665e0224a3d76f36da40bd9012270fa629aa42ed ]
After a loss of transport due to an adapter migration or crash/disconnect
from the host partner there is a tiny window where we can race adjusting
the request_limit of the adapter. The request limit is atomically
increased/decreased to track the number of inflight requests against the
allowed limit of our VIOS partner.
After a transport loss we set the request_limit to zero to reflect this
state. However, there is a window where the adapter may attempt to queue a
command because the transport loss event hasn't been fully processed yet
and request_limit is still greater than zero. The hypercall to send the
event will fail and the error path will increment the request_limit as a
result. If the adapter processes the transport event prior to this
increment the request_limit becomes out of sync with the adapter state and
can result in SCSI commands being submitted on the now reset connection
prior to an SRP Login resulting in a protocol violation.
Fix this race by protecting request_limit with the host lock when changing
the value via atomic_set() to indicate no transport.
