Pass through mode is to allow packets in MAP format to be passed
on to the stack. rmnet driver can be used to process and demultiplex
these packets.
Pass through mode can be enabled when the device is in raw ip mode only.
Conversely, raw ip mode cannot be disabled when pass through mode is
enabled.
Userspace can use pass through mode in conjunction with rmnet driver
through the following steps-
1. Enable raw ip mode on qmi_wwan device
2. Enable pass through mode on qmi_wwan device
3. Create a rmnet device with qmi_wwan device as real device using netlink

While we do handle the additional cursor sizes introduced in NVE4, it looks
like we accidentally broke this when converting over to use Nvidia's
display headers. Since we now use NVVAL in dispnv50/head907d.c in order to
format the value for the cursor layout and NVD9 only had one byte reserved
vs. the 2 bytes reserved in later generations, we end up accidentally
stripping the second bit in the cursor layout format parameter - causing us
to set the wrong cursor size.
This fixes that by adding our own curs_set hook for 917d which uses the
NV917D headers.

Commit f844eb485eb056ad3b67e49f95cbc6c685a73db4 introduced a regression for
NV50, which lead to visual artifacts, tearing and eventual crashes.
In the changes of f844eb485eb056ad3b67e49f95cbc6c685a73db4 only the first line
was correctly translated to the new NVIDIA header macros:
- PUSH_NVSQ(push, NV827C, 0x0110, 0,
- 0x0114, 0);
+ PUSH_MTHD(push, NV827C, SET_PROCESSING,
+ NVDEF(NV827C, SET_PROCESSING, USE_GAIN_OFS, DISABLE));
The lower part ("0x0114, 0") was probably omitted by accident.
This patch restores the push of the missing data and fixes the regression.

====================
mlx5 subfunction support
Parav Pandit says:
This patchset introduces support for mlx5 subfunction (SF).
A subfunction is a lightweight function that has a parent PCI function on
which it is deployed. mlx5 subfunction has its own function capabilities
and its own resources. This means a subfunction has its own dedicated
queues(txq, rxq, cq, eq). These queues are neither shared nor stolen from
the parent PCI function.
When subfunction is RDMA capable, it has its own QP1, GID table and rdma
resources neither shared nor stolen from the parent PCI function.
A subfunction has dedicated window in PCI BAR space that is not shared
with the other subfunctions or parent PCI function. This ensures that all
class devices of the subfunction accesses only assigned PCI BAR space.
A Subfunction supports eswitch representation through which it supports tc
offloads. User must configure eswitch to send/receive packets from/to
subfunction port.
Subfunctions share PCI level resources such as PCI MSI-X IRQs with
their other subfunctions and/or with its parent PCI function.
Subfunction support is discussed in detail in RFC [1] and [2].
RFC [1] and extension [2] describes requirements, design and proposed
plumbing using devlink, auxiliary bus and sysfs for systemd/udev
support. Functionality of this patchset is best explained using real
examples further below.
overview:
--------
A subfunction can be created and deleted by a user using devlink port
add/delete interface.
A subfunction can be configured using devlink port function attribute
before its activated.
When a subfunction is activated, it results in an auxiliary device on
the host PCI device where it is deployed. A driver binds to the
auxiliary device that further creates supported class devices.
example subfunction usage sequence:
-----------------------------------
Change device to switchdev mode:
$ devlink dev eswitch set pci/0000:06:00.0 mode switchdev
Add a devlink port of subfunction flavour:
$ devlink port add pci/0000:06:00.0 flavour pcisf pfnum 0 sfnum 88
Configure mac address of the port function:
$ devlink port function set ens2f0npf0sf88 hw_addr 00:00:00:00:88:88
Now activate the function:
$ devlink port function set ens2f0npf0sf88 state active
Now use the auxiliary device and class devices:
$ devlink dev show
pci/0000:06:00.0
auxiliary/mlx5_core.sf.4
$ ip link show
127: ens2f0np0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
link/ether 24:8a:07:b3:d1:12 brd ff:ff:ff:ff:ff:ff
altname enp6s0f0np0
129: p0sf88: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
link/ether 00:00:00:00:88:88 brd ff:ff:ff:ff:ff:ff
$ rdma dev show
43: rdmap6s0f0: node_type ca fw 16.29.0550 node_guid 248a:0703:00b3:d112 sys_image_guid 248a:0703:00b3:d112

After use inactivate the function:
$ devlink port function set ens2f0npf0sf88 state inactive
Now delete the subfunction port:
$ devlink port del ens2f0npf0sf88

The Ubiquiti U-Fiber Instant SFP GPON module has nonsensical information
stored in its EEPROM. It claims to support all transceiver types including
10G Ethernet. Clear all claimed modes and set only 1000baseX_Full, which is
the only one supported.
This module has also phys_id set to SFF, and the SFP subsystem currently
does not allow to use SFP modules detected as SFFs. Add exception for this
module so it can be detected as supported.
This change finally allows to detect and use SFP GPON module Ubiquiti
U-Fiber Instant on Linux system.
EEPROM content of this SFP module is (where XX is serial number):

The workaround for VSOL V2801F brand based GPON SFP modules added in commit
0d035bed2a4a ("net: sfp: VSOL V2801F / CarlitoxxPro CPGOS03-0490 v2.0
workaround") works only for IDs added explicitly to the list. Since there
are rebranded modules where OEM vendors put different strings into the
vendor name field, we cannot base workaround on IDs only.
Moreover the issue which the above mentioned commit tried to work around is
generic not only to VSOL based modules, but rather to all GPON modules
based on Realtek RTL8672 and RTL9601C chips.
These include at least the following GPON modules:
* V-SOL V2801F
* C-Data FD511GX-RM0
* OPTON GP801R
* BAUDCOM BD-1234-SFM
* CPGOS03-0490 v2.0
* Ubiquiti U-Fiber Instant
* EXOT EGS1
These Realtek chips have broken EEPROM emulator which for N-byte read
operation returns just the first byte of EEPROM data, followed by N-1
zeros.
Introduce a new function, sfp_id_needs_byte_io(), which detects SFP modules
with broken EEPROM emulator based on N-1 zeros and switch to 1 byte EEPROM
reading operation.
Function sfp_i2c_read() now always uses single byte reading when it is
required and when function sfp_hwmon_probe() detects single byte access,
it disables registration of hwmon device, because in this case we cannot
reliably and atomically read 2 bytes as is required by the standard for
retrieving values from diagnostic area.
(These Realtek chips are broken in a way that violates SFP standards for
diagnostic interface. Kernel in this case simply cannot do anything less
of skipping registration of the hwmon interface.)
This patch fixes reading of EEPROM content from SFP modules based on
Realtek RTL8672 and RTL9601C chips. Diagnostic interface of EEPROM stays
broken and cannot be fixed.

The purpose of the delayed work in the SPAN module is to potentially
update the destination port and various encapsulation parameters of SPAN
agents that point to a VLAN device or a GRE tap. The destination port
can change following the insertion of a new route, for example.
SPAN agents that point to a physical port or the CPU port are static and
never change throughout the lifetime of the SPAN agent. Therefore, skip
over them in the delayed work.
This fixes an issue where the delayed work overwrites the policer
that was set on a SPAN agent pointing to the CPU. Modifying the delayed
work to inherit the original policer configuration is error-prone, as
the same will be needed for any new parameter.

Although it's neat to avoid the suffix for the typical case of a
single PMU, it means systems with multiple CMN instances end up with
inconsistent naming. I think it also breaks perf tool's "uncore alias"
logic if the common instance prefix is also the full name of one.
Avoid any surprises by not trying to be clever and simply numbering
every instance, even when it might technically prove redundant.

- Fix pcf2127 reset for imx7d-flex-concentrator board.
- Fix i.MX6 suspend with Thumb-2 kernel.
- Fix ethernet-phy address issue on imx6qdl-sr-som board.
- Fix GPIO3 `gpio-ranges` on i.MX8MP.
- Select SOC_BUS for IMX_SCU driver to fix build issue.
- Fix backlight pwm on imx6qdl-kontron-samx6i which is lost from
#pwm-cells conversion.
- Fix duplicated bus node name for i.MX8MN SoC.
- Fix reset register offset on LS1028A SoC.
- Rename MMC node aliases for imx6q-tbs2910 to keep the MMC device
index consistent with previous kernel version.
- Selecting ARM_GIC_V3 on non-CP15 processors to fix one build
failure with i.MX8M SoC driver.
- Fix typos with status property on imx6qdl-kontron-samx6i board.
- Fix duplicated regulator-name on imx6qdl-gw52xx board.
Aside from i.MX, the bugfixes are all over the place:
- Coccinelle found a refcount imbalance on integrator

BCACHE_SB_VERSION_CDEV_WITH_FEATURES
For super block version < BCACHE_SB_VERSION_CDEV_WITH_FEATURES, it
doesn't make sense to check the feature sets. This patch checks

When an Intel IOMMU is virtualized, and a physical device is
passed-through to the VM, changes of the virtual IOMMU need to be
propagated to the physical IOMMU. The hypervisor therefore needs to
monitor PTE mappings in the IOMMU page-tables. Intel specifications
provide "caching-mode" capability that a virtual IOMMU uses to report
that the IOMMU is virtualized and a TLB flush is needed after mapping to
allow the hypervisor to propagate virtual IOMMU mappings to the physical
IOMMU. To the best of my knowledge no real physical IOMMU reports
"caching-mode" as turned on.
Synchronizing the virtual and the physical IOMMU tables is expensive if
the hypervisor is unaware which PTEs have changed, as the hypervisor is
required to walk all the virtualized tables and look for changes.
Consequently, domain flushes are much more expensive than page-specific
flushes on virtualized IOMMUs with passthrough devices. The kernel
therefore exploited the "caching-mode" indication to avoid domain
flushing and use page-specific flushing in virtualized environments. See
commit 78d5f0f500e6 ("intel-iommu: Avoid global flushes with caching
mode.")
This behavior changed after commit 13cf01744608 ("iommu/vt-d: Make use
of iova deferred flushing"). Now, when batched TLB flushing is used (the
default), full TLB domain flushes are performed frequently, requiring
the hypervisor to perform expensive synchronization between the virtual
TLB and the physical one.
Getting batched TLB flushes to use page-specific invalidations again in
such circumstances is not easy, since the TLB invalidation scheme
assumes that "full" domain TLB flushes are performed for scalability.
Disable batched TLB flushes when caching-mode is on, as the performance
benefit from using batched TLB invalidations is likely to be much
smaller than the overhead of the virtual-to-physical IOMMU page-tables
synchronization.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/fixes
Fixes for omaps for v5.11-rc cycle
The recent changes to switch SoCs to boot with ti-sysc interconnect
target module driver and genpd caused few regressions:
- The omap_prm reset driver needs to clear any reset bits deasserted by
the bootloader or kexec boot for the three reset bit cases. Otherwise
we can have an oops with accelerators starting to boot with potentially
unconfigured MMU for example
- Custom kernel configs are not automatically selecting simple-pm-bus
driver that we now need to probe interconnects so we need to select it
always
- We are not passing legacy platform data in auxdata with simple-pm-bus
like we do for simple-bus. We need to pass auxdata to simple-pm-bus so
it can pass it to of_platform_populate()
Then recent RCU changes started causing splats for cpuidle44xx that now
need RCU_NONIDLE added to the calls in several places
And then we have few device specific fixes:
- We need to remove legacy spi-cs-hig for gta04 display to work, and
set the gpio to active low
- Omap1 specific ohci-omap needs to call gpio_free()
- Droid4 needs to use padconf interrupt for the slider as the edge
gpio interrupts may be lost for deeper idle states

IOMMU Extended Feature Register (EFR) is used to communicate
the supported features for each IOMMU to the IOMMU driver.
This is normally read from the PCI MMIO register offset 0x30,
and used by the iommu_feature() helper function.
However, there are certain scenarios where the information is needed
prior to PCI initialization, and the iommu_feature() function is used
prematurely w/o warning. This has caused incorrect initialization of IOMMU.
This is the case for the commit 6d39bdee238f ("iommu/amd: Enforce 4k
mapping for certain IOMMU data structures")
Since, the EFR is also available in the IVHD header, and is available to
the driver prior to PCI initialization. Therefore, default to using
the IVHD EFR instead.

drm hotplug handling code (drm_client_dev_hotplug()) can wait on mutex,
thus delaying further lt9611uxc IRQ events processing. It was observed
occasionally during bootups, when drm_client_modeset_probe() was waiting
for EDID ready event, which was delayed because IRQ handler was stuck
trying to deliver hotplug event.
Move hotplug notifications from IRQ handler to separate work to be able
to process IRQ events without delays.
