As it is optional and no platform is actually using the secondary bus,
deprecate the qcom,bus-id property. For newer platforms that implement
SPMI PMIC ARB v7 in HW, the X1E80100 approach should be used.

I'd probably split that part off.

I think we usually say "Any context.". But I would just do it like idr.h:
"Any context. It is safe to call this function without locking in your
code."
... but is this true? We really want to say "without page table lock".
Because there must be some way to prevent against concurrent page table
freeing. For example, GUP-fast disables IRQs, whereby page table freeing
code frees using RCU.

Hm, I think you mentioned that we want to be careful with vmf.orig_pte.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark

Yes. Especially as we have these pte_same() checks that might just fail
now because of wrong accessed/dirty bits?
Likely, we just want to read "the real deal" on both sides of the
pte_same() handling.

Not a native speaker; works for me.

Yes, sounds good to me.

* [PATCH v3 5/5] arm64: dts: exynos: gs101: define all PERIC USI nodes

Universal Serial Interface (USI) supports three types of serial
interface such as UART, SPI and I2C. Each protocol works independently.
USI can be configured to work as one of these protocols. Define all the
USI nodes from the PERIC blocks (USI0-14), in all their possible
configurations. These blocks have the TX/RX FIFO depth of 64 bytes.

Right... We'd need to change that too :) Although I suppose table
invalidations are relatively infrequent when compared to leaf
invalidations.

And I'm sure there's plenty more to be found too, heh.

Hmm, but doesn't the deferred TLBI still happen after the RCU critical
section?
I also think I found another bug, so I'll send a v2 with an extra patch...

Ok, long shot after eyeballing the vhost code, but does the diff below
help at all? It looks like vhost_vq_avail_empty() can advance the value
saved in 'vq->avail_idx' but without the read barrier, possibly confusing
vhost_get_vq_desc() in polling mode.

* [PATCH v11 25/28] drm/vc4: tests: Remove vc4_dummy_plane structure
From: Maxime Ripard @ 2024-03-26 15:40 UTC (permalink / raw)
To: Maarten Lankhorst, Thomas Zimmermann, David Airlie, Daniel Vetter,
Jonathan Corbet, Sandy Huang, Heiko Stübner, Chen-Yu Tsai,
Jernej Skrabec, Samuel Holland
Cc: Hans Verkuil, Sebastian Wick, Ville Syrjälä, dri-devel,

In-Reply-To: <20240326-kms-hdmi-connector-state-v11-0-c5680ffcf261@kernel.org>
The vc4_dummy_plane structure was introduced as a mean to add
mock-specific fields.
However, we never really used it and it's still strictly equivalent to
vc4_plane (which is in the same situation vs drm_plane), so we can
simply remove the vc4_dummy_plane structure and make the mock code
cleaner.

* [PATCH v11 23/28] drm/connector: hdmi: Create Infoframe DebugFS entries

In-Reply-To: <20240326-kms-hdmi-connector-state-v11-0-c5680ffcf261@kernel.org>
There has been some discussions recently about the infoframes sent by
drivers and if they were properly generated.
In parallel, there's been some interest in creating an infoframe-decode
tool similar to edid-decode.
Both would be much easier if we were to expose the infoframes programmed
in the hardware. It won't be perfect since we have no guarantee that
it's actually what goes through the wire, but it's the best we can do.

* [PATCH v11 18/28] drm/tests: Add tests for Broadcast RGB property

In-Reply-To: <20240326-kms-hdmi-connector-state-v11-0-c5680ffcf261@kernel.org>
This had a bunch of kunit tests to make sure our code to handle the
Broadcast RGB property behaves properly.
This requires bringing a bit of infrastructure to create mock HDMI
connectors, with custom EDIDs.

* [PATCH v11 17/28] drm/connector: hdmi: Add Broadcast RGB property

In-Reply-To: <20240326-kms-hdmi-connector-state-v11-0-c5680ffcf261@kernel.org>
The i915 driver has a property to force the RGB range of an HDMI output.
The vc4 driver then implemented the same property with the same
semantics. KWin has support for it, and a PR for mutter is also there to
support it.
Both drivers implementing the same property with the same semantics,
plus the userspace having support for it, is proof enough that it's
pretty much a de-facto standard now and we can provide helpers for it.
Let's plumb it into the newly created HDMI connector.

In-Reply-To: <20240326-kms-hdmi-connector-state-v11-0-c5680ffcf261@kernel.org>
The previous patch added the bpc and format an HDMI connector needs to
be set up with for a given connector state.
Let's add a few tests to make sure it works as expected.

* [PATCH v11 15/28] drm/connector: hdmi: Compute bpc and format automatically
From: Maxime Ripard @ 2024-03-26 15:40 UTC (permalink / raw)
To: Maarten Lankhorst, Thomas Zimmermann, David Airlie, Daniel Vetter,
Jonathan Corbet, Sandy Huang, Heiko Stübner, Chen-Yu Tsai,

In-Reply-To: <20240326-kms-hdmi-connector-state-v11-0-c5680ffcf261@kernel.org>
Now that we have all the infrastructure needed, we can add some code
that will, for a given connector state and mode, compute the best output
format and bpc.
The algorithm is equivalent to the one already found in i915 and vc4.

The previous patch adds a new hook for HDMI connectors to filter out
configurations based on the TMDS character rate. Let's add some tests to
make sure it works as expected.

* [PATCH v11 13/28] drm/connector: hdmi: Add custom hook to filter TMDS character rate
From: Maxime Ripard @ 2024-03-26 15:40 UTC (permalink / raw)

In-Reply-To: <20240326-kms-hdmi-connector-state-v11-0-c5680ffcf261@kernel.org>
Most of the HDMI controllers have an upper TMDS character rate limit
they can't exceed. On "embedded"-grade display controllers, it will
typically be lower than what high-grade monitors can provide these days,
so drivers will filter the TMDS character rate based on the controller
capabilities.
To make that easier to handle for drivers, let's provide an optional
hook to be implemented by drivers so they can tell the HDMI controller
helpers if a given TMDS character rate is reachable for them or not.
This will then be useful to figure out the best format and bpc count for
a given mode.

* [PATCH v11 11/28] drm/connector: hdmi: Calculate TMDS character rate

Most HDMI drivers have some code to calculate the TMDS character rate,
usually to adjust an internal clock to match what the mode requires.
Since the TMDS character rates mostly depends on the resolution, whether
we need to repeat pixels or not, the bpc count and the format, we can
now derive it from the HDMI connector state that stores all those infos
and remove the duplication from drivers.

A lot of HDMI drivers have some variation of the formula to calculate
the TMDS character rate from a mode, but few of them actually take all
parameters into account.
Let's create a helper to provide that rate taking all parameters into
account.

In-Reply-To: <20240326-kms-hdmi-connector-state-v11-0-c5680ffcf261@kernel.org>
Just like BPC, we'll add support for automatic selection of the output
format for HDMI connectors.
Let's add the needed defaults and fields for now.
