Introduce support for Qualcomm new video acceleration hardware i.e. 
iris, used for video stream decoding.

Iris is a multi pipe based hardware that offloads video stream decoding 
from the application processor (AP). It supports H.264 decoding. The AP 
communicates with hardware through a well defined protocol, called as 
host firmware interface (HFI), which provides fine-grained and 
asynchronous control over individual hardware features.

This driver implements upgraded HFI gen2 to communicate with firmware.
It supports SM8550 which is based out of HFI gen 2. It also supports 
SM8250 which is based out of HFI gen1.

This driver comes with below capabilities:
- V4L2 complaint video driver with M2M and STREAMING capability.
- Supports H264 decoder.

This driver comes with below features:
- Centralized resource management.
- Centralized management of core and instance states.
- Defines platform specific capabilities and features. As a results, it 
  provides a single point of control to enable/disable a given feature 
  depending on specific platform capabilities.
- Handles various video recommended sequences, like DRC, Drain, Seek, 
  EOS.
- Implements asynchronous communication with hardware to achieve better 
  experience in low latency usecases.
- Output and capture planes are controlled independently. Thereby
  providing a way to reconfigure individual plane.
- Native hardware support of LAST flag which is mandatory to align with 
  port reconfiguration and DRAIN sequence as per V4L guidelines.

Changes since v4:
- Fixed commit message length for all patches (Krzysztof)
- Migrated back to remove from remove_new (Uwe Kleine-König)
- Removed support for g_volatle_ctrl (Hans)
- Added changes to update minimum buffer count whenever the hardware 
  requirement changes (Hans)

- Link to v4: https://lore.kernel.org/r/20241014-qcom-video-iris-v4-v4-0-c5eaa4e9ab9e@quicinc.com

Changes since v3:
- Fixed the style issues with dt binding (Krzysztof)
- Pushed  the patch to add maintainers to end of the series (Krzysztof, 
  Dmitry)
- Moved the resource initialization next to probe in iris_probe.c and 
  squashed the patch of probe and resource initialization (Krzysztof)
- Removed error prints from probe function (Krzysztof)
- Defined bit fields used for register read/write with macros for better 
  context (Bryan)
- Converted if/else to switch/case wherever applicable (Bryan)
- Removed defensive NULL checks wherever not required (Bryan, Krzysztof)
- Removed core->state checks except for below scenarios (Bryan)
  - When reverse thread (firmware) can move the state of the core to 
    error state.
  - When client can force close the driver and there are still pending 
    firmware responses to be read from shared queues (msg and dbg)
  - For PM operations, since its a delayed autosuspend work and sys 
    error handler from the reverse thread can move the state to core 
    deinit state anytime.
- Acquiring core->lock only for below scenarios (Bryan)
  - Writing to registers.
- Reading/Writing from/to shared queues.
  - Traversing the instance list of core.
  - To protect the core->state when it can changed by reverse thread.
- Acquiring inst->lock only for below scenario which is needed (Bryan)
  - Serializing the forward and reverse thread
  - To protect the inst structure where the values can be modified by
    firmware.
- Removed usage of core->power_enabled (Krzysztof, Bryan)
- Removed usage of mutex_is_locked  (Krzysztof, Bryan)
- Use C structure for instance caps (Dmitry)
- Split the ctrl ops patch by keeping only the defines, struct and caps 
  needed to intialize the ctrl handler and to implement s/g_ctrl
  (Dmitry)
- Removed the instance state checks to allow v4l2-ctl, relying on
  standard vb2 checks instead. (Hans)
- Converted APIs to void wherever applicable except for below (Bryan)
  - iris_hfi_gen2_handle_session_error and
    iris_hfi_gen2_handle_session_property cannot be converted to void
    even though they always return 0.
    Because these are two of the handlers invoked from
    iris_hfi_gen2_handle_session_response and are of
    iris_hfi_gen2_inst_hfi_range struct type, where same prototype is
    followed for all handlers and return type of all handers should be
    'int'.
    And we cannot have a switch case/if else to handle these
    responses from firmware because we need to parse the responses in a
    particular sequence.
    That's why we opted for this handler based design instead of
    introducing multiple for loop with code duplication.
- Fixed issues reported by kernel bot.
- Fixed v4l2 compliance issue reported with "-s" options based on the 
  inputs from Hans.
- Addressed all other review comments and made some code improvements.

Changes since v2:
- introduced support for HFI gen1.
- deprecated Encoder and HEVC, VP9 codecs.
- removed custom vb2 mem ops and used standard framework instead.
- added support for mmap streaming mode.
- migrated all the buffer APIs to mem2mem helper functions.
- registered iris buffer with vb2 framework.
- migrated to clk_bulk, reset_bulk and icc_bulk APIs.
- used pm_domain_attach/detach_list APIs.
- migrated to read/writel and other available helpers for register
  access instead of custom wrappers.
- added documentation for various structures.
- addressed many other review comments from v2.

Note: A harmless onetime error log "Lucid PLL latch failed. Output may
be unstable!" is seen during bootup.  It doesn't impact any video 
usecase and is currently under discussion.

Static tools like checkpatch, smatch, dt_binding_check, sparse and
Coccinelle run successfully with this driver.

This driver is tested with v4l2-ctl[1] and Gstreamer[2].

Implement open, close and poll ops.

Open:
Configure the vb2 queue and v4l2 file handler. Allocate a video instance
and add the instance to core instance list.

Close:
Free the instance and remove it from core instance list.

Poll:
Wait for an event on vb2 src and vb2 dst queues.

Introduce core state management for iris driver with necessary queues
needed for host firmware communication.

There are 3 types of queues:
Command queue - driver to write any command to firmware.
Message queue - firmware to send any response to driver.
Debug queue - firmware to write debug messages.
Initialize and configire shared queues during probe.

Different states for core:
IRIS_CORE_DEINIT - default state.
IRIS_CORE_INIT - core state with core initialized. FW loaded and HW
brought out of reset, shared queues established between host driver and
firmware.
IRIS_CORE_ERROR - error state.

Host firmware interface (HFI) is well defined set of interfaces for
communication between host driver and firmware. The commands and
responses are exchanged in form of packets. One or multiple packets are
grouped under packet header. Each packet has packet type which describes
the specific HFI and payload which holds the corresponding value for
that HFI.

capabilities. Capabilities are features supported by a specific platform
(SOC). Each capability is defined with min, max, range, default value
and corresponding HFI. Implement s_ctrl and g_volatile_ctrl ctrl ops.

In stream on, send HFI_CMD_START on capture and output planes to start
the processing on respective planes.

During stream off, send HFI_CMD_STOP to firmware which is a synchronous
command. After the response is received from firmware, the session is
closed on firmware.

Introduce different states for instance and state transitions.

IRIS_INST_INIT - video instance is opened.
IRIS_INST_INPUT_STREAMING - stream on is completed on output plane.
IRIS_INST_OUTPUT_STREAMING - stream on is completed on capture plane.
IRIS_INST_STREAMING - stream on is completed on both output and capture
planes.
IRIS_INST_DEINIT - video instance is closed.
IRIS_INST_ERROR - error state.

During stream on, set some mandatory properties to firmware to start a
session. Set all v4l2 properties set by client, to firmware prepared
with the dependency graph.

Implement vb2 ops for buf queue. Below are the different buffer
attributes:
BUF_ATTR_DEFERRED - buffer queued by client but not submitted to
firmware.
BUF_ATTR_PENDING_RELEASE - buffers requested to be released from
firmware.
BUF_ATTR_QUEUED - buffers submitted to firmware.
BUF_ATTR_DEQUEUED - buffers received from firmware.
BUF_ATTR_BUFFER_DONE - buffers sent back to vb2.

Handle the response sent by firmware, when source change is detected by
firmware. Read the parameter subscribed to firmware for source change to
detect the parameter with changed value. Raise the source change event
to client and update the instance sub state.

Mark the last buffer from before the source change with the
V4L2_BUF_FLAG_LAST flag and return to client.

The decoder is stopped after it completes the dynamic resolution change
sequence. Handle VIDIOC_STREAMOFF() and VIDIOC_STREAMON() on the CAPTURE
queue by client to resume the decoding process.

handle the V4L2_DEC_CMD_STOP by initiating drain sequence to firmware.
Process and decode all OUTPUT buffers queued by the client before the
VIDIOC_DECODER_CMD() was issued and mark the last buffer with
V4L2_BUF_FLAG_LAST flag. Decoder is stopped after processing the last
buffer.

Resume the decoder when one of below are issued by client:
- V4L2_DEC_CMD_START
- pair of VIDIOC_STREAMOFF() and VIDIOC_STREAMON() on the CAPTURE queue
- pair of VIDIOC_STREAMOFF() and VIDIOC_STREAMON() on the OUTPUT queue

> - Removed state checks from try/g/s_fmt ioctls (Hans)
> - Removed wait_prepare() and wait_finish callbacks (Hans)
> - Added support for remove_bufs (Hans)
> - Added module param based configurability to select between venus and

> 
> Changes since v3:
> - Fixed the style issues with dt binding (Krzysztof)
> - Pushed  the patch to add maintainers to end of the series (Krzysztof,
>    Dmitry)
> - Moved the resource initialization next to probe in iris_probe.c and
>    squashed the patch of probe and resource initialization (Krzysztof)
> - Removed error prints from probe function (Krzysztof)
> - Defined bit fields used for register read/write with macros for better
>    context (Bryan)
> - Converted if/else to switch/case wherever applicable (Bryan)
> - Removed defensive NULL checks wherever not required (Bryan, Krzysztof)
> - Removed core->state checks except for below scenarios (Bryan)
>    - When reverse thread (firmware) can move the state of the core to
>      error state.
>    - When client can force close the driver and there are still pending
>      firmware responses to be read from shared queues (msg and dbg)
>    - For PM operations, since its a delayed autosuspend work and sys
>      error handler from the reverse thread can move the state to core
>      deinit state anytime.
> - Acquiring core->lock only for below scenarios (Bryan)
>    - Writing to registers.
> - Reading/Writing from/to shared queues.
>    - Traversing the instance list of core.
>    - To protect the core->state when it can changed by reverse thread.
> - Acquiring inst->lock only for below scenario which is needed (Bryan)
>    - Serializing the forward and reverse thread
>    - To protect the inst structure where the values can be modified by
>      firmware.
> - Removed usage of core->power_enabled (Krzysztof, Bryan)
> - Removed usage of mutex_is_locked  (Krzysztof, Bryan)
> - Use C structure for instance caps (Dmitry)
> - Split the ctrl ops patch by keeping only the defines, struct and caps
>    needed to intialize the ctrl handler and to implement s/g_ctrl
>    (Dmitry)
> - Removed the instance state checks to allow v4l2-ctl, relying on
>    standard vb2 checks instead. (Hans)
> - Converted APIs to void wherever applicable except for below (Bryan)
>    - iris_hfi_gen2_handle_session_error and
>      iris_hfi_gen2_handle_session_property cannot be converted to void
>      even though they always return 0.
>      Because these are two of the handlers invoked from
>      iris_hfi_gen2_handle_session_response and are of
>      iris_hfi_gen2_inst_hfi_range struct type, where same prototype is
>      followed for all handlers and return type of all handers should be
>      'int'.
>      And we cannot have a switch case/if else to handle these
>      responses from firmware because we need to parse the responses in a
>      particular sequence.
>      That's why we opted for this handler based design instead of
>      introducing multiple for loop with code duplication.
> - Fixed issues reported by kernel bot.
> - Fixed v4l2 compliance issue reported with "-s" options based on the
>    inputs from Hans.
> - Addressed all other review comments and made some code improvements.
> 
> Changes since v2:
> - introduced support for HFI gen1.
> - deprecated Encoder and HEVC, VP9 codecs.
> - removed custom vb2 mem ops and used standard framework instead.
> - added support for mmap streaming mode.
> - migrated all the buffer APIs to mem2mem helper functions.
> - registered iris buffer with vb2 framework.
> - migrated to clk_bulk, reset_bulk and icc_bulk APIs.
> - used pm_domain_attach/detach_list APIs.
> - migrated to read/writel and other available helpers for register
>    access instead of custom wrappers.
> - added documentation for various structures.
> - addressed many other review comments from v2.
>

Setting a mask to GENMASK() - 1 sounds weird. Is it really what you want?
I so, why?

Thanks,

Hi Mauro,

the value of this dma mask should be 0xe0000000 -1.

The background for the same is, 0xe0000000 onward memory space is allocated
for IO register space so we are restricting the driver buffer allocations
to 0xe0000000 - 1.

Based on the comments received in the past, we are using GENMASK to
generate 0xe0000000.

Does this answer your query or I missed something?

Thanks,
Dikshita

I tested this on an x1e based machine, a Surface Laptop 7. I had some
errors with loading the firmware which triggered some warnings when
trying to tear down the driver. I've pasted the WARNs at the end of
this mail.

I was using the firmware from linux-firmware, as packaged by distros:

4d2dae9a8187b728939e9c79fa68012b  qcom/vpu/vpu30_p4.mbn

It appears to be signed by a test key, which I assume was the cause of
the failure. Replacing it with a properly signed version worked, and I
was able successfully decode a test video with ffplay:

$ ffplay -codec:v h264_v4l2m2m test.mp4
...
[h264_v4l2m2m @ 0xffff500054b0] Using device /dev/video0

It might be new behavior triggered by this series:

https://lore.kernel.org/all/0-v3-b3a5b5937f56+7bb-arm_no_split_jgg@nvidia.com/

Your allocation:

        queue_size = ALIGN((sizeof(*q_tbl_hdr) + (IFACEQ_QUEUE_SIZE *
IFACEQ_NUMQ)), SZ_4K);
        core->iface_q_table_vaddr = dma_alloc_attrs(core->dev, queue_size,
                                                    &core->iface_q_table_daddr,
                                                    GFP_KERNEL,
DMA_ATTR_WRITE_COMBINE);


and the free:

        dma_free_attrs(core->dev, sizeof(struct iris_hfi_queue_table_header),
                       core->iface_q_table_vaddr, core->iface_q_table_daddr,
                       DMA_ATTR_WRITE_COMBINE);

So probably your bug, but hidden until Jason's change caused it to WARN.

I'm not sure it will do what you want. (0xe0000000 -1) matches ~BIT(29). Perhaps
you wanted to use ~0xe0000000.

value of dma mask is coming as expected with GENMASK(31, 29) - 1

qcom-iris aa00000.video-codec: dma_mask DFFFFFFF (0xe0000000 -1)

Isn't this just the equivalent of GENMASK(28, 0)? Can't you use that?

It's much easier to understand than GENMASK()-1.

Sure, I can use either ~GENMASK(29, 29) or ~BIT(29),
Please let me know which would be better?

Too early in the morning, this suggestion was clearly wrong.

~BIT(29).

It's really weird to just disable a single bit, so I think some comments
explaining why this mask is needed would be good (if there aren't comments
already).

Hi Joel,

I tried again with firmware (qcom/vpu/vpu30_p4.mbn) available in
linux-firmware[1] on my setup i.e SM8550 MTP and don't see any issue with
firmware load.
could you pls share from where you are taking the firmware?

[1] git clone
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git

Thanks,
Dikshita

I tested this some more, and seems ~BIT(29) doesn't work, as its still
conflicting with the register space.
Correct value would be GENMASK(31,30) + GENMASK(28,0) to set the exact bits
to get the desired value i.e 0xe0000000 -1

Odd, perhaps a 64 vs 32 bit issue?

Honestly, in this case I would prefer to just go with the actual hex value
0xdfffffff together with an explanatory comment.

Of course. MTP is not fused to reject firmware not signed by a
particular vendor key. Production devices are. Please test that the
driver works correctly if the firmware gets rejected by TZ.

We moved to GENMASK way to address comment on previous version, but sure

If I understood it right, bits 0-31 can be used, but the hardware has some
issue using bit 29 at the mask. Could you please comment why it can't be
used?

Btw, as this is a mask, IMO the better would be to document that all bits
except for BIT(29) can be used with something like:

	/* Bit 29 can't be used because ... */
	 .dma_mask = GENMASK(31, 0) - BIT(29)

Thanks,
Mauro

That would not be a correct statement, We don't have issue with using BIT
29 with mask but upper limit of DMA address available to use is 0xdfffffff.

I'd keep the original representation of the DMA address mask. This is
not an register to represent it via GENMASK. It is used by the driver to
set the hardware limitation on the upper bound of DMA address range.

.dma_mask = 0xe0000000 - 1

because we set it through dma_set_mask_and_coherent() which expects a
mask we subtract 1.

Yes, I agree. I see the venus driver does the same thing, so let's follow
that example for consistency.

This could be an indication that some resources are not described
correctly and could potentially require both binding and driver changes
to address.

This is also something which could cause trouble later (e.g. during
suspend) even if you manage to get the clock running after boot.

Generally, you should not be introducing any new warnings; they are
there to let you know that something is wrong.

Where is this issue being discussed?

I think we at least need a public analysis and understanding of the
problem before merging this.

Could you please post the DT changes required for sm8550 so that people
can test this series more easily? You can do it in a separate series if
you prefer (with a link to this series in the cover letter) or as part
of this one (at the end, with a note saying that those changes should go
through the qcom SoC tree).

You should also say something in the cover letter about sm8250 now being
supported by two mainline drivers and how you propose to handle that
conflict.

Why do you want to use a module parameter for this? What would be the
default configuration? (Module parameters should generally be avoided.)

Why not simply switch to the new driver (and make sure that the new
driver is selected if the old one was enabled in the kernel config)?

Surely you don't want to have to add every new platform to two tables

AFAICT nothing is preventing venus from binding even when 'prefer_venus'

This was discussed during v4 [1] and implemented as per suggestion

Its about the platform in migration i.e sm8250. Since new driver is not yet
feature parity with old driver, choice is provided to client if it wants to use
the new driver (default being old driver for sm8250)

Because the new driver doesn't yet have feature parity with the venus
driver. So it was agreed that developers provide upgrade path to allow
users to gradually test and switch to the new driver. When the feature
parity is achieved, the plan is to switch default to point to the Iris
driver, then after a few releases start removing platforms from Venus.

I'd agree here, this list should go. We should only list platforms under
the migration.

The name should follow other names in the driver.
`video_drv_should_bind` doesn't have a common prefix.

Also export it and use it from the venus driver if Iris is enabled.

First, the background and motivation for this still needs to go in the
commit message (and be mentioned in the cover letter).

Second, what you implemented here is not even equivalent to what was
done in the mdm drm driver since that module parameter is honoured by
both drivers so that at most one driver tries to bind to the platform
device.

With this patch as it stands, which driver ends up binding depends on
things like link order and what driver has been built a module, etc. (as
I pointed out below).

This should be described in the commit message, along with details on
what the delta is so that the reasoning can be evaluated.

And I'm still not sure using a module parameter for this is the right
thing to do as it is generally something that should be avoided.

I understand your concern of using module params.
I will modify it to rely on Kconfig to select the driver (suggested by
Hans) instead of module param.
something like:
config VIDEO_QCOM_IRIS
        tristate "Qualcomm iris V4L2 decoder driver"
       ...
        depends on VIDEO_QCOM_VENUS=n || COMPILE_TEST

Please don't. This makes it impossible to perform side-by-side comparison. Also as venus and iris drivers are not completely equivalent wrt supported platforms, distributions will have to select whether to disable support for older platforms or for new platforms: Kconfig dependency will make it impossible to enable support for both kinds.

Also as venus and iris drivers are not completely equivalent wrt supported platforms, distributions will have to select whether to disable support for older platforms or for new platforms: Kconfig dependency will make it impossible to enable support for both kinds.

An alternative is that the module option is placed under

#if defined(CONFIG_VIDEO_QCOM_IRIS) && defined(CONFIG_VIDEO_QCOM_VENUS)

So it only activates if both drivers are compiled.

But the fact that both drivers can work for the same hardware is something that
must be clearly documented. Probably in a comment block before this module option.
Possibly also in the Kconfigs for the IRIS and VENUS drivers.

Things that are unusual require explanation, so in this case I'd like to see:

1) Why are there two drivers?
2) Why allow runtime-selection of which driver to use? (E.g. side-by-side comparison)
3) Which hardware supports only venus, only iris, or both?
4) What is the road forward? (I assume that venus is removed once feature parity is reached?)

	Hans

sm8250 support is to removed and all HFI_6XX platforms of which sm8250 
is one, are expected to be supported by Iris once feature parity is 
upstream.

HFI <= HFI_4XX will continue to be venus, including any new upstream 
submissions for HFI_4XX.

Unless/until Iris gets upstream feature parity, we will continue to add 
new HFI_6XX SoCs to venus.

One drawback to this approach is; if CONFIG_QCOM_VENUS=n and 
CONFIG_QCOM_IRIS=m you still need to-do

zcat /proc/config.gz | grep -e VENUS -e IRIS
CONFIG_VIDEO_QCOM_IRIS=m
# CONFIG_VIDEO_QCOM_VENUS is not set

rmmod iris
modprobe iris prefer_venus=0

which is awkward.

Certainly if venus is off the parameter should default to false.

Perhaps I've missed the resolution of this discussion but how exactly 
are we fixing the "racy" nature of binding here ?

Shouldn't there be a parallel venus patch which either has its own 
module parameter to quiesce binding in favour of iris ?

i.e if

CONFIG_QCOM_VENUS=m and CONFIG_QCOM_IRIS=m

rmmod iris
rmmod venus

(sleep $((RANDOM % 3600)); (modprobe iris prefer_venus=0) &> /dev/null & 
disown) &

(sleep $((RANDOM % 3600)); (modprobe venus) &> /dev/null & disown) &

Will do what exactly ?

I almost typed "either has its own variable _or_ reads the iris 
variable" but then didn't.

Shouldn't venus have its own quiescence variable caveated to the 
transition list too ?

Caveated to sm8250.

Not just the parameter. The whole function should become a stub if
either iris or venus is off.

Venus should call video_drv_should_bind() too. Possibly it's worth
separating this function and a table to a helper kernel module, so that
the venus driver doesn't suddenly get a runtime dependency on iris if
both are enabled.

Nice question. I'd add iris.prefer_venus=0 to kernel commandline and let
it live there for a transition period. It should fix the possible race
condition here.

Taniya Das proposed a patchset to reconfigure PLL in the clk-alpha-pll
which allows the videocc-sm8550 driver to configure it correctly.
https://lore.kernel.org/linux-arm-msm/20250113-support-pll-reconfigure-v1-0-1fae6bc1062d@quicinc.com/T/

I tested the Iris driver with this patchset and I am no longer seeing
the Lucid PLL latch failed warning.

Why? You can have two kernel builds and run the same tests. And you
obviously cannot run iris and venus on the same hardware at once anyway.

You shouldn't have both enabled. The only reason for keeping support
for the same hardware in both drivers is that the iris support is
incomplete and considered experimental. No one should enable that except
for development and evaluation purposes until the driver is up to par.
And then you drop support from the old driver along with the config
option.

Thanks for the pointer. Please make sure to reference this series (and
summarise the underlying issue) when resending this series.

Judging from a quick look the approach taken there seems like a bit of a
hack so it may not get merged in its current form. IIUC fixing the PLL
issue properly may depend on adding support for multiple power domains
to the clock drivers.

It would be good if you can add your comment to the PLL fix series [1] so that
the patch owner can discuss on your suggestion.

At once not. But unbindng and rebinding another driver works perfectly.

That's the plan. This modparam is a temporal thing for transition
period. And yes, as a developers / platform enablers we want to be able
to have a quick turnaround between drivers.

Please stop forcing your decisions on other people. The Linux kernel and
its development process has always been about providing a possibility,
not a policy.

That's just not true. The rule is to not have two drivers for the same
hardware (even if we very rarely have accepted some well-motivated
exceptions).

I understand that you may have an unorthodox view of this as you work on
the MSM DRM driver, but hiding incomplete and broken code behind module
parameters so that you can game the upstreaming process (e.g. like you
did for the eDP PSR feature) is simply not a model that anyone should
follow.

Let me point you the aic7xxx story, we had, if my memory is correct,
three drivers working with the same hardware at some point, during
transition period.

Regarding eDP PSR. It wasn't my implementation, so that's not correct
comparison. MDP5 -> DPU migration is mine and yes, it is implemented in
this way as we can trigger CI jobs having a single kernel, as developers
we can switch between MDP5 and DPU drivers in a quick way, etc.

As I also mentioned, there have been exceptions to the rule.

Sure, but that module parameter is still there two years later, the
functionality is still incomplete and from what I've heard has since
also bitrotted (psr_enabled).

Done right and enabled by default this feature would have been very
useful giving, for example, users of the X13s a 2 h battery boost.
Instead, as expected, no one cares about fixing the code after it was
"mainlined" or runs the bits that did work often enough to detect when
it breaks further. Everyone loses.

I don't know the backstory there, but at least the commit message didn't
mention anything about a plan to transition from one to the other.
