Hmm, does venus not support the combined firmware yet?  Elsewhere
we've moved away from split fw to using a single ELF file..

Actually, isn't the .mbn the joined fw?  If so all you need to do is
remove the other files?

.mbn is the complete firmware image. We have migrated to .mbn for sc7280, while the
Initial days of sc7280 was with .mdt binaries (split ones). So to support the boards which
Have not upgraded the driver, we are retaining all binaries.

Thanks for the feedback (on and off-list). I will push a V2 of the pull request
with the following changes:

1. Update both split and non-split binaries for venus-5.4 (SC7180). Also,
update the version in WHENCE. We can remove the legacy split images in a later
commit if it is feasible to do so.
2. Remove the split firmware images for vpu-2.0 (SC7280). There is no released
device that uses the older firmware loader. I have tested to make sure the
non-split image can be loaded and that the venus media functions work on a
SC7280 device using a ChromeOS kernel based on 5.15.
3. Update the VPU-2.0 non-split binaries to the latest version and update the
version in the WHENCE file.

The mdt loader doesn't care about the file extension, the mdt loader
will determine the type of the file based on the file contents. Thus
I'd suggest adding only mbn files and adding a compat symlinks
pointing from venus.mdt to venus.mbn

sc7180 is using venus-5.4 firmware and currently the name is passed as "qcom/venus-5.4/venus.mdt" while making call to "request_firmware()"
https://elixir.bootlin.com/linux/latest/source/drivers/media/platform/qcom/venus/core.c#L765
https://elixir.bootlin.com/linux/latest/source/drivers/media/platform/qcom/venus/firmware.c#L104

IIUC, before we remove the split files (.mdt), we should also make change in driver to update the name from .mdt to .mbn.
Please help to clarify if we can remove the split files with driver still referring to "qcom/venus-5.4/venus.mdt" in call to request_firmware().

Thanks for the code links! That is helpful.

I think Dmitry is saying that we could remove the venus.b0* files and
replace the venus.mdt
file with a symbolic link to venus.mbn. This would achieve the goal of
reducing the size of the
files that are stored and deployed, while staying compatible with the
existing driver code.

The best solution would probably be to change the driver to load the
.mbn files, but using the
symbolic link seems like a good intermediate solution. If there is no
complaint about Dmitiry's
suggestion, I will make a PR V3 with an additional commit to remove
the split files and use a
symbolic link linking venus.mdt to venus.mbn. This commit will precede
the commit to update
venus 5.4 firmware.
