Pull pci fixes from Bjorn Helgaas:
- Restructure j721e_pcie_probe() so we don't dereference a NULL pointer
(Bjorn Helgaas)
- Add a kirin_pcie_data struct to identify different Kirin variants to
fix probe failure for controllers with an internal PHY (Bjorn
Helgaas)

PCI: kirin: Add dev struct for of_device_get_match_data()
PCI: j721e: Initialize pcie->cdns_pcie before using it
|
|
Bean reported that a622435fbe1a ("PCI: kirin: Prefer
of_device_get_match_data()") broke kirin_pcie_probe() because it assumed
match data of 0 was a failure when in fact, it meant the match data was
"(void *)PCIE_KIRIN_INTERNAL_PHY".
Therefore, probing of "hisilicon,kirin960-pcie" devices failed with -EINVAL
and an "OF data missing" message.
Add a struct kirin_pcie_data to encode the PHY type. Then the result of
of_device_get_match_data() should always be a non-NULL pointer to a struct
kirin_pcie_data that contains the PHY type.
Fixes: a622435fbe1a ("PCI: kirin: Prefer of_device_get_match_data()")

crng_finalize_init() returns instantly if it is called for another pool
than primary_crng. The test whether crng_finalize_init() is still required
can be moved to the relevant caller in crng_reseed(), and
crng_need_final_init can be reset to false if crng_finalize_init() is
called with workqueues ready. Then, no previous callsite will call
crng_finalize_init() unless it is needed, and we can get rid of the
superfluous function parameter.

When account() is called, and the amount of entropy dips below
random_write_wakeup_bits, we wake up the random writers, so that they
can write some more in. However, the RNDZAPENTCNT/RNDCLEARPOOL ioctl
sets the entropy count to zero -- a potential reduction just like
account() -- but does not unblock writers. This commit adds the missing
logic to that ioctl to unblock waiting writers.

The rngd kernel thread may sleep indefinitely if the entropy count is
kept above random_write_wakeup_bits by other entropy sources. To make
best use of multiple sources of randomness, mix entropy from hardware
RNGs into the pool at least once within CRNG_RESEED_INTERVAL.

The polling loop for the register change in iommu_ga_log_enable() needs
to have a udelay() in it. Otherwise the CPU might be faster than the
IOMMU hardware and wrongly trigger the WARN_ON() further down the code
stream. Use a 10us for udelay(), has there is some hardware where
activation of the GA log can take more than a 100ms.
A future optimization should move the activation check of the GA log
to the point where it gets used for the first time. But that is a
bigger change and not suitable for a fix.

From 4.17 onwards the ixgbevf driver uses build_skb() to build an skb
around new data in the page buffer shared with the ixgbe PF.
This uses either a 2K or 3K buffer, and offsets the DMA mapping by
NET_SKB_PAD + NET_IP_ALIGN. When using a smaller buffer RXDCTL is set to
ensure the PF does not write a full 2K bytes into the buffer, which is
actually 2K minus the offset.
However on the 82599 virtual function, the RXDCTL mechanism is not
available. The driver attempts to work around this by using the SET_LPE
mailbox method to lower the maximm frame size, but the ixgbe PF driver
ignores this in order to keep the PF and all VFs in sync[0].
This means the PF will write up to the full 2K set in SRRCTL, causing it
to write NET_SKB_PAD + NET_IP_ALIGN bytes past the end of the buffer.
With 4K pages split into two buffers, this means it either writes
NET_SKB_PAD + NET_IP_ALIGN bytes past the first buffer (and into the
second), or NET_SKB_PAD + NET_IP_ALIGN bytes past the end of the DMA
mapping.
Avoid this by only enabling build_skb when using "large" buffers (3K).
These are placed in each half of an order-1 page, preventing the PF from
writing past the end of the mapping.
[0]: Technically it only ever raises the max frame size, see
ixgbe_set_vf_lpe() in ixgbe_sriov.c

The recent overhaul of pci_irq_get_affinity() introduced a regression when
pci_irq_get_affinity() is called for an MSI-X interrupt which was not
allocated with affinity descriptor information.
The original code just returned a NULL pointer in that case, but the rework
added a WARN_ON() under the assumption that the corresponding WARN_ON() in
the MSI case can be applied to MSI-X as well.
In fact the MSI warning in the original code does not make sense either
because it's legitimate to invoke pci_irq_get_affinity() for a MSI
interrupt which was not allocated with affinity descriptor information.
Remove it and just return NULL as the original code did.

adding indirectly accesses to the device log directory log page through
ata_log_supported(). Reading this log page causes SATADOM-ML 3ME devices

In some cases, the IPA hardware needs to request the always-on
subsystem (AOSS) to coordinate with the IPA microcontroller to
retain IPA register values at power collapse. This is done by
issuing a QMP request to the AOSS microcontroller. A similar
request ondoes that request.
We must get and hold the "QMP" handle early, because we might get
back EPROBE_DEFER for that. But the actual request should be sent
while we know the IPA clock is active, and when we know the
microcontroller is operational.

that the host can't touch the device, report RFKILL immediately
upon register() and don't wait for the CSME firmware to let us
know again about the link protection state.

enough and we'll have a window of time during which it can bring

iwlmei can trigger a hardware RFKILL when the CSME firmware
does not want the host to touch the device.
But then, iwlmvm reports RFKILL which makes cfg80211 update
iwlmvm about RFKILL. iwlmvm then thinks there is a change in
the _software_ rfkill and it calls rfkill_blocked() to fetch
the RFKILL state. This returns that RFKILL is blocked (because
of iwlmei) and iwlmvm tells iwlmei that _software_ RFKILL is
asserted.
This is a bug of course.
Fix this by checking explicitly the software RFKILL state and
not the overall RFKILL state.

The shared area is a DMA memory allocated in the host and
mapped so that the host and the CSME firmware can
exchange data. It is mapped through a dedicated PCI device
that is driven by the mei bus driver.
The bus driver is in charge of allocating and mapping this
memory. It also needs to configure the CSME firmware with
a specific set of commands, so that the CSME firmware will
know that this memory is meant to be used by its internal
WLAN module.
For this, the CSME firmware first needs to completely
initialize its WLAN module and only then get the mapping
request.
The problem is that the mei bus enumeration completes
before the WLAN is completely ready. This means that
the WLAN module's initialization is racing with iwlmei's
allocation and mapping flow.
Testing showed a problem in resume flows where iwlmei
was too fast and the DMA mapping failed.
Add a retry mechanism to make sure that we will succeed
to map the memory.

The check makes sure that we can look at the ip header.
We first need to check that the basic ip header (20 bytes)
can be pulled before we look at the field that will teach
us how long is the ip header. This is why there are two
checks.
The second check was wrong and smatch pointed that
sizeof(ip_hdrlen(skb) - sizeof(*iphdr)) can't be right.
Looking at the code again made me think that we really
need ip_hdrlen(skb) since we want to make sure all the
IP header is in the buffer header. This will allow us
to set the transport offset and from there to look
at the transport header (TCP / UDP).

There are a couple of bugs in this function:
1. It is declared as a non-static function, even though
it's only used in one file.
2. Its return value should be of type u32 but it returns
(in some cases) -1.
Fix them by making this function static and returning an
error value of type unsigned.
In addition, we're assigning the return value of this function
as the legacy rate even if the function returned an error value.
Fix this by assigning the lowest rate in this case.

Controller deletion/reset, immediately followed by or concurrent with
a reconnect, is hard failing the connect attempt resulting in a
complete loss of connectivity to the controller.
In the connect request, fabrics looks for an existing controller with
the same address components and aborts the connect if a controller
already exists and the duplicate connect option isn't set. The match
routine filters out controllers that are dead or dying, so they don't
interfere with the new connect request.
When NVME_CTRL_DELETING_NOIO was added, it missed updating the state
filters in the nvmf_ctlr_matches_baseopts() routine. Thus, when in this
new state, it's seen as a live controller and fails the connect request.
Correct by adding the DELETING_NIO state to the match checks.

The eDP link rate reported by the DP_MAX_LINK_RATE dpcd register (0xa) is
contradictory to the highest rate supported reported by
EDID (0xc = LINK_RATE_RBR2). The effects of this compounded with commit
'4a8ca46bae8a ("drm/amd/display: Default max bpc to 16 for eDP")' results
in no display modes being found and a dark panel.
For now, simply force the maximum supported link rate for the eDP attached
2018 15" Apple Retina panels.
Additionally, we must also check the firmware revision since the device ID
reported by the DPCD is identical to that of the more capable 16,1,
incorrectly quirking it. We also use said firmware check to quirk the
refreshed 15,1 models with Vega graphics as they use a slightly newer
firmware version.
