This is not really a firmware error. We need to reload the firmware, but
this doesn't mean that we should consider this as a firmware error.
When the firmware was restarted upon resume, this wasn't felt by the
driver. Now that we keep the firmware running during suspend even if we
don't have wowlan, this started to pop-up.

If the firmware fails to start the session protection, then we
do call iwl_mvm_roc_finished() here, but that won't do anything
at all because IWL_MVM_STATUS_ROC_P2P_RUNNING was never set.
Set IWL_MVM_STATUS_ROC_P2P_RUNNING in the failure/stop path.
If it started successfully before, it's already set, so that
doesn't matter, and if it didn't start it needs to be set to
clean up.
Not doing so will lead to a WARN_ON() later on a fresh remain-
on-channel, since the link is already active when activated as
it was never deactivated.

iwl_fwrt_read_err_table can return true also when it failed to read
the memory. In this case, err_id argument is not initialized,
but the callers are still using it.
Simply initialize it to 0. If the error table was read successfully it'll
be overridden.

The firmware dumps can be pretty big, and since we use single
pages for each SG table entry, even the table itself may end
up being an order-5 allocation. Build chained tables so that
we need not allocate a higher-order table here.
This could be improved and cleaned up, e.g. by using the SG
pool code or simply kvmalloc(), but all of that would require
also updating the devcoredump first since that frees it all,
so we need to be more careful. SG pool might also run against
the CONFIG_ARCH_NO_SG_CHAIN limitation, which is irrelevant
here.
Also use _devcd_free_sgtable() for the error paths now, much
simpler especially since it's in two places now.

vmclock_probe() uses an "out:" label to return from the function on
error. This indicates that some cleanup operation is necessary.
However the label does not do anything as all resources are managed
through devres, making the code slightly harder to read.
Remove the label and just return directly.

vmclock_remove() tries to detect the successful registration of the misc
device based on the value of its minor value.
However that check is incorrect if the misc device registration was not
attempted in the first place.
Always initialize the minor number, so the check works properly.

If vmclock_ptp_register() fails during probing, vmclock_remove() is
called to clean up the ptp clock and misc device.
It uses dev_get_drvdata() to access the vmclock state.
However the driver data is not yet set at this point.

The settings for all GPIOs are locked by default in bcm_kona_gpio_reset.
The settings for a GPIO are unlocked when requesting it as a GPIO, but
not when requesting it as an interrupt, causing the IRQ settings to not
get applied.
Fix this by making sure to unlock the right bits when an IRQ is requested.
To avoid a situation where an IRQ being released causes a lock despite
the same GPIO being used by a GPIO request or vice versa, add an unlock
counter and only lock if it reaches 0.

The GPIO lock/unlock functions clear/write a bit to the relevant
register for each bank. However, due to an oversight the bit that
was being written was based on the total GPIO number, not the index
of the GPIO within the relevant bank, causing it to fail for any
GPIO above 32 (thus any GPIO for banks above bank 0).
Fix lock/unlock for these banks by using the correct bit.

Commit df542f669307 ("net: stmmac: Switch to zero-copy in
non-XDP RX path") makes DMA write received frame into buffer at offset
of NET_SKB_PAD and sets page pool parameters to sync from offset of
NET_SKB_PAD. But when Header Payload Split is enabled, the header is
written at offset of NET_SKB_PAD, while the payload is written at
offset of zero. Uncorrect offset parameter for the payload breaks dma
coherence [1] since both CPU and DMA touch the page buffer from offset
of zero which is not handled by the page pool sync parameter.
And in case the DMA cannot split the received frame, for example,
a large L2 frame, pp_params.max_len should grow to match the tail
of entire frame.

Rework the workaround as the lookup tables always fits into the bitfield,
and the default values are defined by the hardware and cannot be 0:
Guard against false positive with a WARN_ON check to make the compiler
happy: The offset range is pre-checked against the sorted imp_lookup_table
values and overflow should not happen and would be caught by a warning and
return in error.
Also guard against a true positive found during the max_vswing lookup, as a
max vswing value can be 802000 or 803000 microvolt depending on the current
impedance. Therefore set the default impedence index.

The iopf_queue_remove_device() helper removes a device from the per-iommu
iopf queue when PRI is disabled on the device. It responds to all
outstanding iopf's with an IOMMU_PAGE_RESP_INVALID code and detaches the
device from the queue.
However, it fails to release the group structure that represents a group
of iopf's awaiting for a response after responding to the hardware. This
can cause a memory leak if iopf_queue_remove_device() is called with
pending iopf's.
Fix it by calling iopf_free_group() after the iopf group is responded.

Commit 8c87215dd3a2 ("ata: libahci_platform: support non-consecutive
port numbers") modified ahci_platform_get_resources() to allow
identifying the ports of a controller that are defined as child nodes of
the controller node in order to support non-consecutive port numbers (as
defined by the platform device tree).
However, this commit also erroneously sets bit 0 of
hpriv->mask_port_map when the platform devices tree does not define port
child nodes, to match the fact that the temporary default number of
ports used in that case is 1 (which is also consistent with the fact
that only index 0 of hpriv->phys[] is initialized with the call to
ahci_platform_get_phy(). But doing so causes ahci_platform_init_host()
to initialize and probe only the first port, even if this function
determines that the controller has in fact multiple ports using the
capability register of the controller (through a call to
ahci_nr_ports()). This can be seen with the ahci_mvebu driver (Armada
385 SoC) with the second port declared as "dummy":
ahci-mvebu f10a8000.sata: masking port_map 0x3 -> 0x1
ahci-mvebu f10a8000.sata: AHCI vers 0001.0000, 32 command slots, 6 Gbps, platform mode

Fix this issue by removing setting bit 0 of hpriv->mask_port_map when

"Fix a recently introduced kernel crash due to a NULL pointer
dereference during system-wide suspend (Rafael Wysocki)"
* tag 'pm-6.14-rc2-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
PM: sleep: core: Restrict power.set_active propagation
|
|
Commit 3775fc538f53 ("PM: sleep: core: Synchronize runtime PM status of
parents and children") exposed an issue related to simple_pm_bus_pm_ops
that uses pm_runtime_force_suspend() and pm_runtime_force_resume() as
bus type PM callbacks for the noirq phases of system-wide suspend and
resume.
The problem is that pm_runtime_force_suspend() does not distinguish
runtime-suspended devices from devices for which runtime PM has never
been enabled, so if it sees a device with runtime PM status set to
RPM_ACTIVE, it will assume that runtime PM is enabled for that device
and so it will attempt to suspend it with the help of its runtime PM
callbacks which may not be ready for that. As it turns out, this
causes simple_pm_bus_runtime_suspend() to crash due to a NULL pointer
dereference.
Another problem related to the above commit and simple_pm_bus_pm_ops is
that setting runtime PM status of a device handled by the latter to
RPM_ACTIVE will actually prevent it from being resumed because
pm_runtime_force_resume() only resumes devices with runtime PM status
set to RPM_SUSPENDED.
To mitigate these issues, do not allow power.set_active to propagate
beyond the parent of the device with DPM_FLAG_SMART_SUSPEND set that
will need to be resumed, which should be a sufficient stop-gap for the
time being, but they will need to be properly addressed in the future
because in general during system-wide resume it is necessary to resume
all devices in a dependency chain in which at least one device is going
to be resumed.

If a QP is modified to error state and a flush CQE process is triggered,
the subsequent QP destruction mbox can still be successfully posted but
will be blocked in HW until the flush CQE process finishes. This causes
further mbox posting timeouts in driver. The blocking time is related
to QP depth. Considering an extreme case where SQ depth and RQ depth
are both 32K, the blocking time can reach about 135ms.
This patch adds a retry mechanism for mbox posting. For each try, FW
waits 15ms for HW to complete the previous mbox, otherwise return a
timeout error code to driver. Counting other time consumption in FW,
set 8 tries for mbox posting and a 5ms time gap before each retry to
increase to a sufficient timeout limit.

When a weak pull-up is present on the SDO line, regmap_update_bits fails
to write both the SOFTRESET and SDOACTIVE bits because it incorrectly
reads them as already set.
Since the soft reset disables the SDO line, performing a
read-modify-write operation on ADI_SPI_CONFIG_A to enable the SDO line
doesn't make sense. This change directly writes to the register instead
of using regmap_update_bits.
