The Voltorb device uses a speaker codec different from the original
Corsola device. When the Voltorb device tree was first added, the new
codec was added as a separate node when it should have just replaced the
existing one.
Merge the two nodes. The only differences are the compatible string and
the GPIO line property name. This keeps the device node path for the
speaker codec the same across the MT8186 Chromebook line. Also rename
the related labels and node names from having rt1019p to speaker codec.

It is impossible to add each and every possible DDP path combination
for each and every possible combination of SoC and board: right now,
this driver hardcodes configuration for 10 SoCs and this is going to
grow larger and larger, and with new hacks like the introduction of
mtk_drm_route which is anyway not enough for all final routes as the
DSI cannot be connected to MERGE if it's not a dual-DSI, or enabling
DSC preventively doesn't work if the display doesn't support it, or
others.
Since practically all display IPs in MediaTek SoCs support being
interconnected with different instances of other, or the same, IPs
or with different IPs and in different combinations, the final DDP
pipeline is effectively a board specific configuration.
Implement OF graphs support to the mediatek-drm drivers, allowing to
stop hardcoding the paths, and preventing this driver to get a huge
amount of arrays for each board and SoC combination, also paving the
way to share the same mtk_mmsys_driver_data between multiple SoCs,
making it more straightforward to add support for new chips.
Note that the OVL_ADAPTOR software component driver needs relatively
big changes in order to fully support OF Graphs (and more SoCs anyway)
and such changes will come at a later time.
As of now, the mtk_disp_ovl_adaptor driver takes the MERGE components
(for example, on mt8195, merge 1 to 4) dynamically so, even though
later updates to the ovl-adaptor driver will *not* require bindings
changes, the merge1-4 will be temporarily omitted in the graph for the
MT8195 SoC.
This means that an example graph for this SoC looks like:
mdp_rdma (0 ~ 7) -> padding (0 ~ 7) -> ethdr -> merge5
and the resulting path in this driver will be `ovl_adaptor -> merge5`
Later updates to the ovl adaptor will expand it to support more SoCs
and, in turn, to also fully support graphs.

The display IPs in MediaTek SoCs support being interconnected with
different instances of DDP IPs (for example, merge0 or merge1) and/or
with different DDP IPs (for example, rdma can be connected with either
color, dpi, dsi, merge, etc), forming a full Display Data Path that
ends with an actual display.
The final display pipeline is effectively board specific, as it does
depend on the display that is attached to it, and eventually on the
sensors supported by the board (for example, Adaptive Ambient Light
would need an Ambient Light Sensor, otherwise it's pointless!), other
than the output type.
Add support for OF graphs to most of the MediaTek DDP (display) bindings
to add flexibility to build custom hardware paths, hence enabling board
specific configuration of the display pipeline and allowing to finally
migrate away from using hardcoded paths.
Please note that - while this commit retains retro-compatibility with
old device trees - it will break the ABI for mediatek,dsi and for
mediatek,dpi for the sake of consistency between the `ports` in all
MediaTek DRM drivers versus DRM bridge drivers as in the previous
binding, MediaTek was using `port` (implicitly, port@0) as an OUTPUT,
while now the first port is an INPUT, and the second one is an OUTPUT,
which is consistent with other DRM drivers which can be chained to
drm/mediatek.
As for maintainability concerns, I am aware that the old device tree
will not be actively tested anymore, but retrocompatibility breakages
will *not* be more likely to happen in the future because any addition
to the graph (new drivers) will be done only for features present on
newer SoCs, keeping the old ones (and their default pipeline) untouched.

Allison Karlitskaya <allison.karlitskaya@redhat.com> says:
In context of my work on composefs/bootc I've been testing the new support
for directly mounting files with erofs (ie: without a loopback device) and
it's working well. Thanks for adding this feature --- it's a huge quality
of life improvement for us.
I've observed a strange behaviour, though: when mounting a file as an
erofs, if you read() the filesystem context fd, you always get the
following error message reported: Can't lookup blockdev.
That's caused by the code in erofs_fc_get_tree() trying to call
get_tree_bdev() and recovering from the error in case it was ENOTBLK and
CONFIG_EROFS_FS_BACKED_BY_FILE. Unfortunately, get_tree_bdev() logs the
error directly on the fs_context, so you get the error message even on
successful mounts.
It looks something like this at the syscall level:
fsopen("erofs", FSOPEN_CLOEXEC) = 3
fsconfig(3, FSCONFIG_SET_FLAG, "ro", NULL, 0) = 0
fsconfig(3, FSCONFIG_SET_STRING, "source", "/home/lis/src/mountcfs/cfs", 0)
= 0
fsconfig(3, FSCONFIG_CMD_CREATE, NULL, NULL, 0) = 0
fsmount(3, FSMOUNT_CLOEXEC, 0) = 5
move_mount(5, "", AT_FDCWD, "/tmp/composefs.upper.KuT5aV",
MOVE_MOUNT_F_EMPTY_PATH) = 0
read(3, "e /home/lis/src/mountcfs/cfs: Can't lookup blockdev\n", 1024) = 52
This is kernel 6.12.0-0.rc0.20240926git11a299a7933e.13.fc42.x86_64 from

PRMT needs to find the correct type of block to translate the PA-VA
mapping for EFI runtime services.
The issue arises because the PRMT is finding a block of type
EFI_CONVENTIONAL_MEMORY, which is not appropriate for runtime services
as described in Section 2.2.2 (Runtime Services) of the UEFI
Specification [1]. Since the PRM handler is a type of runtime service,
this causes an exception when the PRM handler is called.
[Firmware Bug]: Unable to handle paging request in EFI runtime service
WARNING: CPU: 22 PID: 4330 at drivers/firmware/efi/runtime-wrappers.c:341
__efi_queue_work+0x11c/0x170
Call trace:
Let PRMT find a block with EFI_MEMORY_RUNTIME for PRM handler and PRM
context.
If no suitable block is found, a warning message will be printed, but
the procedure continues to manage the next PRM handler.
However, if the PRM handler is actually called without proper allocation,
it would result in a failure during error handling.
By using the correct memory types for runtime services, ensure that the
PRM handler and the context are properly mapped in the virtual address
space during runtime, preventing the paging request error.
The issue is really that only memory that has been remapped for runtime
by the firmware can be used by the PRM handler, and so the region needs
to have the EFI_MEMORY_RUNTIME attribute.

net/mlx5: Refactor esw QoS to support generalized operations
This patch series from the team to mlx5 core driver consists of one main
QoS part followed by small misc patches.
This main part (patches 1 to 11) by Carolina refactors the QoS handling
to generalize operations on scheduling groups and vports. These changes
are necessary to support new features that will extend group
functionality, introduce new group types, and support deeper
hierarchies.
Additionally, this refactor updates the terminology from "group" to
"node" to better reflect the hardware’s rate hierarchy and its use
of scheduling element nodes.
Simplify group scheduling element creation:
- net/mlx5: Refactor QoS group scheduling element creation
Refactor to support generalized operations for QoS:
- net/mlx5: Introduce node type to rate group structure
- net/mlx5: Add parent group support in rate group structure
- net/mlx5: Restrict domain list insertion to root TSAR ancestors
- net/mlx5: Rename vport QoS group reference to parent
- net/mlx5: Introduce node struct and rename group terminology to node
- net/mlx5: Refactor vport scheduling element creation function
- net/mlx5: Refactor vport QoS to use scheduling node structure
- net/mlx5: Remove vport QoS enabled flag
Support generalized operations for QoS elements:
- net/mlx5: Simplify QoS scheduling element configuration

Currently, when VFs are created, two flow tables are added for the eswitch:
the "fdb" table, which contains rules for each VF and the "vepa_fdb" table.
In the default VEB mode, the vepa_fdb table is empty. When switching to
VEPA mode, flow steering rules are added to vepa_fdb. Even though the
vepa_fdb table is empty in VEB mode, its presence adds some cost to packet
processing. In some workloads, this leads to drops which are reported by
the rx_discards_phy ethtool counter.
In order to improve performance, only create vepa_fdb when in VEPA mode.

On sync reset flow, firmware may request a PF, which already
acknowledged the unload event, to move to drop mode. Drop mode means
that this PF will reduce polling frequency, as this PF is not going to
have another active part in the reset, but only reload back after the
reset.

Simplify the configuration of QoS scheduling elements by removing the
separate functions `esw_qos_node_config` and `esw_qos_vport_config`.
Instead, directly use the existing `esw_qos_sched_elem_config` function
for both nodes and vports.
This unification helps in generalizing operations on scheduling
elements nodes.

Remove the `enabled` flag from the `vport->qos` struct, as QoS now
relies solely on the `sched_node` pointer to determine whether QoS
features are in use.
Currently, the vport `qos` struct consists only of the `sched_node`,
introducing an unnecessary two-level reference. However, the qos struct
is retained as it will be extended in future patches to support new QoS
features.

Refactor the vport QoS structure by moving group membership and
scheduling details into the `mlx5_esw_sched_node` structure.
This change consolidates the vport into the rate hierarchy by unifying
the handling of different types of scheduling element nodes.
In addition, add a direct reference to the mlx5_vport within the
mlx5_esw_sched_node structure, to ensure that the vport is easily
accessible when a scheduling node is associated with a vport.

Modify the vport scheduling element creation function to get the parent
node directly, aligning it with the group creation function.
This ensures a consistent flow for scheduling elements creation, as the
parent nodes already contain the device and parent element index.

Introduce the `mlx5_esw_sched_node` struct, consolidating all rate
hierarchy related details, including membership and scheduling
parameters.
Since the group concept aligns with the `mlx5_esw_sched_node`, replace
the `mlx5_esw_rate_group` struct with it and rename the "group"
terminology to "node" throughout the rate hierarchy.
All relevant code paths and structures have been updated to use the
"node" terminology accordingly, laying the groundwork for future
patches that will unify the handling of different types of members
within the rate hierarchy.

Rename the `group` field in the `mlx5_vport` structure to `parent` to
clarify the vport's role as a member of a parent group and distinguish
it from the concept of a general group.
Additionally, rename `group_entry` to `parent_entry` to reflect this
update.
This distinction will be important for handling more complex group
structures and scheduling elements.

Introduce a `parent` field in the `mlx5_esw_rate_group` structure to
support hierarchical group relationships.
The `parent` can reference another group or be set to `NULL`,
indicating the group is connected to the root TSAR.
This change enables the ability to manage groups in a hierarchical
structure for future enhancements.
