9fcef1e37d iommu/arm-smmu-v3: Acknowledge pri/event queue overflow if any
[ Upstream commit 67ea0b7ce41844eae7c10bb04dfe66a23318c224 ]

When an overflow occurs in the PRI queue, the SMMU toggles the overflow
flag in the PROD register. To exit the overflow condition, the PRI thread
is supposed to acknowledge it by toggling this flag in the CONS register.
Unacknowledged overflow causes the queue to stop adding anything new.

Currently, the priq thread always writes the CONS register back to the
SMMU after clearing the queue.

The writeback is not necessary if the OVFLG in the PROD register has not
been changed, no overflow has occured.

This commit checks the difference of the overflow flag between CONS and
PROD register. If it's different, toggles the OVACKFLG flag in the CONS
register and write it to the SMMU.

The situation is similar for the event queue.
The acknowledge register is also toggled after clearing the event
queue but never propagated to the hardware. This would only be done the
next time when executing evtq thread.

Unacknowledged event queue overflow doesn't affect the event
queue, because the SMMU still adds elements to that queue when the
overflow condition is active.
But it feel nicer to keep SMMU in sync when possible, so use the same
way here as well.

fe4d708668 iommu: Add gfp parameter to iommu_ops::map
[ Upstream commit 781ca2de89bae1b1d2c96df9ef33e9a324415995 ]

Add a gfp_t parameter to the iommu_ops::map function.
Remove the needless locking in the AMD iommu driver.

The iommu_ops::map function (or the iommu_map function which calls it)
was always supposed to be sleepable (according to Joerg's comment in
this thread: https://lore.kernel.org/patchwork/patch/977520/ ) and so
should probably have had a "might_sleep()" since it was written. However
currently the dma-iommu api can call iommu_map in an atomic context,
which it shouldn't do. This doesn't cause any problems because any iommu
driver which uses the dma-iommu api uses gfp_atomic in it's
iommu_ops::map function. But doing this wastes the memory allocators
atomic pools.

ea057ac8c9 iommu/arm-smmu-v3: fix event handling soft lockup
[ Upstream commit 30de2b541af98179780054836b48825fcfba4408 ]

During event processing, events are read from the event queue one
by one until the queue is empty.If the master device continuously
requests address access at the same time and the SMMU generates
events, the cyclic processing of the event takes a long time and
softlockup warnings may be reported.

arm-smmu-v3 arm-smmu-v3.34.auto: event 0x0a received:
arm-smmu-v3 arm-smmu-v3.34.auto: 	0x00007f220000280a

Kernel panic - not syncing: softlockup: hung tasks

Fix this by calling cond_resched() after the event information is
printed.

480494e28a iommu/arm-smmu-v3: Use WRITE_ONCE() when changing validity of an STE
[ Upstream commit d71e01716b3606a6648df7e5646ae12c75babde4 ]

If, for some bizarre reason, the compiler decided to split up the write
of STE DWORD 0, we could end up making a partial structure valid.

Although this probably won't happen, follow the example of the
context-descriptor code and use WRITE_ONCE() to ensure atomicity of the
write.

53fa56f06e FROMGIT: drivers/iommu: Initialise module 'owner' field in iommu_device_set_ops()
Requiring each IOMMU driver to initialise the 'owner' field of their
'struct iommu_ops' is error-prone and easily forgotten. Follow the
example set by PCI and USB by assigning THIS_MODULE automatically when
registering the ops structure with IOMMU core.

6b1400f260 iommu/arm-smmu-v3: Don't display an error when IRQ lines are missing
[ Upstream commit f7aff1a93f52047739af31072de0ad8d149641f3 ]

Since commit 7723f4c5ec ("driver core: platform: Add an error message
to platform_get_irq*()"), platform_get_irq_byname() displays an error
when the IRQ isn't found. Since the SMMUv3 driver uses that function to
query which interrupt method is available, the message is now displayed
during boot for any SMMUv3 that doesn't implement the combined
interrupt, or that implements MSIs.

[   20.700337] arm-smmu-v3 arm-smmu-v3.7.auto: IRQ combined not found
[   20.706508] arm-smmu-v3 arm-smmu-v3.7.auto: IRQ eventq not found
[   20.712503] arm-smmu-v3 arm-smmu-v3.7.auto: IRQ priq not found
[   20.718325] arm-smmu-v3 arm-smmu-v3.7.auto: IRQ gerror not found

Use platform_get_irq_byname_optional() to avoid displaying a spurious
error.

e83861a6a0 FROMLIST: iommu/arm-smmu: Prevent forced unbinding of Arm SMMU drivers
Forcefully unbinding the Arm SMMU drivers is a pretty dangerous operation,
since it will likely lead to catastrophic failure for any DMA devices
mastering through the SMMU being unbound. When the driver then attempts
to "handle" the fatal faults, it's very easy to trip over dead data
structures, leading to use-after-free.

On John's machine, he reports that the machine was "unusable" due to
loss of the storage controller following a forced unbind of the SMMUv3
driver:

  | # cd ./bus/platform/drivers/arm-smmu-v3
  | # echo arm-smmu-v3.0.auto > unbind
  | hisi_sas_v2_hw HISI0162:01: CQE_AXI_W_ERR (0x800) found!
  | platform arm-smmu-v3.0.auto: CMD_SYNC timeout at 0x00000146
  | [hwprod 0x00000146, hwcons 0x00000000]

Prevent this forced unbinding of the drivers by setting "suppress_bind_attrs"
to true.

Pull LED updates from Jacek Anaszewski:
 "In this cycle we've finally managed to contribute the patch set
  sorting out LED naming issues. Besides that there are many changes
  scattered among various LED class drivers and triggers.

  LED naming related improvements:

   - add new 'function' and 'color' fwnode properties and deprecate
     'label' property which has been frequently abused for conveying
     vendor specific names that have been available in sysfs anyway

   - introduce a set of standard LED_FUNCTION* definitions

   - introduce a set of standard LED_COLOR_ID* definitions

   - add a new {devm_}led_classdev_register_ext() API with the
     capability of automatic LED name composition basing on the
     properties available in the passed fwnode; the function is
     backwards compatible in a sense that it uses 'label' data, if
     present in the fwnode, for creating LED name

   - add tools/leds/get_led_device_info.sh script for retrieving LED
     vendor, product and bus names, if applicable; it also performs
     basic validation of an LED name

   - update following drivers and their DT bindings to use the new LED
     registration API:

        - leds-an30259a, leds-gpio, leds-as3645a, leds-aat1290, leds-cr0014114,
          leds-lm3601x, leds-lm3692x, leds-lp8860, leds-lt3593, leds-sc27xx-blt

  Other LED class improvements:

   - replace {devm_}led_classdev_register() macros with inlines

   - allow to call led_classdev_unregister() unconditionally

   - switch to use fwnode instead of be stuck with OF one

  LED triggers improvements:

   - led-triggers:
        - fix dereferencing of null pointer
        - fix a memory leak bug

   - ledtrig-gpio:
        - GPIO 0 is valid

  Drop superseeded apu2/3 support from leds-apu since for apu2+ a newer,
  more complete driver exists, based on a generic driver for the AMD
  SOCs gpio-controller, supporting LEDs as well other devices:

   - drop profile field from priv data

   - drop iosize field from priv data

   - drop enum_apu_led_platform_types

   - drop superseeded apu2/3 led support

   - add pr_fmt prefix for better log output

   - fix error message on probing failure

  Other misc fixes and improvements to existing LED class drivers:

   - leds-ns2, leds-max77650:
        - add of_node_put() before return

   - leds-pwm, leds-is31fl32xx:
        - use struct_size() helper

   - leds-lm3697, leds-lm36274, leds-lm3532:
        - switch to use fwnode_property_count_uXX()

   - leds-lm3532:
        - fix brightness control for i2c mode
        - change the define for the fs current register
        - fixes for the driver for stability
        - add full scale current configuration
        - dt: Add property for full scale current.
        - avoid potentially unpaired regulator calls
        - move static keyword to the front of declarations
        - fix optional led-max-microamp prop error handling

   - leds-max77650:
        - add of_node_put() before return
        - add MODULE_ALIAS()
        - Switch to fwnode property API

   - leds-as3645a:
        - fix misuse of strlcpy

   - leds-netxbig:
        - add of_node_put() in netxbig_leds_get_of_pdata()
        - remove legacy board-file support

   - leds-is31fl319x:
        - simplify getting the adapter of a client

   - leds-ti-lmu-common:
        - fix coccinelle issue
        - move static keyword to the front of declaration

   - leds-syscon:
        - use resource managed variant of device register

   - leds-ktd2692:

cdb8a3c346 iommu/arm-smmu-v3: Avoid locking on invalidation path when not using ATS
When ATS is not in use, we can avoid taking the 'devices_lock' for the
domain on the invalidation path by simply caching the number of ATS
masters currently attached. The fiddly part is handling a concurrent
->attach() of an ATS-enabled master to a domain that is being
invalidated, but we can handle this using an 'smp_mb()' to ensure that
our check of the count is ordered after completion of our prior TLB
invalidation.

This also makes our ->attach() and ->detach() flows symmetric wrt ATS
interactions.

353e3cf859 iommu/arm-smmu-v3: Fix ATC invalidation ordering wrt main TLBs
When invalidating the ATC for an PCIe endpoint using ATS, we must take
care to complete invalidation of the main SMMU TLBs beforehand, otherwise
the device could immediately repopulate its ATC with stale translations.

Hooking the ATC invalidation into ->unmap() as we currently do does the
exact opposite: it ensures that the ATC is invalidated *before*  the
main TLBs, which is bogus.

Move ATC invalidation into the actual (leaf) invalidation routines so
that it is always called after completing main TLB invalidation.

b5e86196b8 iommu/arm-smmu-v3: Disable detection of ATS and PRI
Detecting the ATS capability of the SMMU at probe time introduces a
spinlock into the ->unmap() fast path, even when ATS is not actually
in use. Furthermore, the ATC invalidation that exists is broken, as it
occurs before invalidation of the main SMMU TLB which leaves a window
where the ATC can be repopulated with stale entries.

Given that ATS is both a new feature and a specialist sport, disable it
for now whilst we fix it properly in subsequent patches. Since PRI
requires ATS, disable that too.

It turns out that we've always relied on some subtle ordering guarantees
when inserting commands into the SMMUv3 command queue. With the recent
changes to elide locking when possible, these guarantees become more
subtle and even more important.

that we don't have to derive the behaviour from scratch each time it
comes up on the list.

functional change since the extra parameter is ignored for now.

298f78895b iommu/io-pgtable: Rename iommu_gather_ops to iommu_flush_ops
In preparation for TLB flush gathering in the IOMMU API, rename the
iommu_gather_ops structure in io-pgtable to iommu_flush_ops, which
better describes its purpose and avoids the potential for confusion
between different levels of the API.

f632a8170a Driver Core and debugfs changes for 5.3-rc1
Here is the "big" driver core and debugfs changes for 5.3-rc1
 
 It's a lot of different patches, all across the tree due to some api
 changes and lots of debugfs cleanups.  Because of this, there is going
 to be some merge issues with your tree at the moment, I'll follow up
 with the expected resolutions to make it easier for you.
 
 Other than the debugfs cleanups, in this set of changes we have:
 	- bus iteration function cleanups (will cause build warnings
 	  with s390 and coresight drivers in your tree)
 	- scripts/get_abi.pl tool to display and parse Documentation/ABI
 	  entries in a simple way
 	- cleanups to Documenatation/ABI/ entries to make them parse
 	  easier due to typos and other minor things
 	- default_attrs use for some ktype users
 	- driver model documentation file conversions to .rst
 	- compressed firmware file loading
 	- deferred probe fixes
 
 All of these have been in linux-next for a while, with a bunch of merge
 issues that Stephen has been patient with me for.  Other than the merge
 issues, functionality is working properly in linux-next :)

8dd8f005bd iommu/arm-smmu-v3: Invalidate ATC when detaching a device
We make the invalid assumption in arm_smmu_detach_dev() that the ATC is
clear after calling pci_disable_ats(). For one thing, only enabling the
PCIe ATS capability constitutes an implicit invalidation event, so the
comment was wrong. More importantly, the ATS capability isn't necessarily
disabled by pci_disable_ats() in a PF, if the associated VFs have ATS
enabled. Explicitly invalidate all ATC entries in arm_smmu_detach_dev().
The endpoint cannot form new ATC entries because STE.EATS is clear.

900a85ca43 iommu/arm-smmu-v3: Fix compilation when CONFIG_CMA=n
When compiling a kernel without support for CMA, CONFIG_CMA_ALIGNMENT

 #define Q_MAX_SZ_SHIFT   (PAGE_SHIFT + CONFIG_CMA_ALIGNMENT)

Fix the breakage by capping the maximum queue size based on MAX_ORDER
when CMA is not enabled.

4f41845b34 iommu/io-pgtable: Replace IO_PGTABLE_QUIRK_NO_DMA with specific flag
IO_PGTABLE_QUIRK_NO_DMA is a bit of a misnomer, since it's really just
an indication of whether or not the page-table walker for the IOMMU is
coherent with the CPU caches. Since cache coherency is more than just a
quirk, replace the flag with its own field in the io_pgtable_cfg
structure.

92ce7e83b4 driver_find_device: Unify the match function with class_find_device()
The driver_find_device() accepts a match function pointer to
filter the devices for lookup, similar to bus/class_find_device().
However, there is a minor difference in the prototype for the
match parameter for driver_find_device() with the now unified
version accepted by {bus/class}_find_device(), where it doesn't
accept a "const" qualifier for the data argument. This prevents
us from reusing the generic match functions for driver_find_device().

For this reason, change the prototype of the driver_find_device() to
make the "match" parameter in line with {bus/class}_find_device()
and adjust its callers to use the const qualifier. Also, we could
now promote the "data" parameter to const as we pass it down
as a const parameter to the match functions.

d25f6ead16 iommu/arm-smmu-v3: Increase maximum size of queues
We've been artificially limiting the size of our queues to 4k so that we
don't end up allocating huge amounts of physically-contiguous memory at
probe time. However, 4k is only enough for 256 commands in the command
queue, so instead let's try to allocate the largest queue that the SMMU
supports, retrying with a smaller size if the allocation fails.

The caveat here is that we have to limit our upper bound based on
CONFIG_CMA_ALIGNMENT to ensure that our queue allocations remain
natually aligned, which is required by the SMMU architecture.

3f54c447df iommu/arm-smmu-v3: Don't disable SMMU in kdump kernel
Disabling the SMMU when probing from within a kdump kernel so that all
incoming transactions are terminated can prevent the core of the crashed
kernel from being transferred off the machine if all I/O devices are
behind the SMMU.

Instead, continue to probe the SMMU after it is disabled so that we can
reinitialise it entirely and re-attach the DMA masters as they are reset.
Since the kdump kernel may not have drivers for all of the active DMA
masters, we suppress fault reporting to avoid spamming the console and
swamping the IRQ threads.
