Sumit GargandAbel Vesa c89eb978c9 firmware: qcom_scm: Migrate to generic PAS service
With the availability of generic PAS service, let's add SCM calls as
a backend to keep supporting legacy QTEE interfaces. The exported
qcom_scm* wrappers will get dropped once all the client drivers get
migrated as part of future patches.

Sumit GargandAbel Vesa 10cb128d7a firmware: qcom: Add a generic PAS service
Qcom platforms has the legacy of using non-standard SCM calls
splintered over the various kernel drivers. These SCM calls aren't
compliant with the standard SMC calling conventions which is a
prerequisite to enable migration to the FF-A specifications from Arm.

OP-TEE as an alternative trusted OS to Qualcomm TEE (QTEE) can't
support these non-standard SCM calls. And even for newer architectures
using S-EL2 with Hafnium support, QTEE won't be able to support SCM
calls either with FF-A requirements coming in. And with both OP-TEE
and QTEE drivers well integrated in the TEE subsystem, it makes further
sense to reuse the TEE bus client drivers infrastructure.

The added benefit of TEE bus infrastructure is that there is support
for discoverable/enumerable services. With that client drivers don't
have to manually invoke a special SCM call to know the service status.

So enable the generic Peripheral Authentication Service (PAS) provided
by the firmware. It acts as the common layer with different TZ
backends plugged in whether it's an SCM implementation or a proper
TEE bus based PAS service implementation.

The HP EliteBook X G2q 14" Next Gen AI PC is a Snapdragon X2 Elite
(Glymur) laptop whose firmware exposes EFI variables through QSEECOM.
Add its board compatible to the QSEECOM allowlist so that EFI variable
access (efivarfs) works on this machine.

Without it the kernel reports "qseecom: untested machine, skipping" and
efivarfs is empty.

Fix the FF-A driver RX/TX buffer sizing logic to respect the maximum
buffer size advertised by firmware, while retaining compatibility with
older implementations that may reject PAGE_SIZE-rounded buffers.
Also fix a NULL pointer dereference in ffa_partition_info_get() by

Adrian Ng Ho YinandDinh Nguyen bba85375f8 firmware: stratix10-svc: fix teardown order in remove to prevent race
In stratix10_svc_drv_remove(), stratix10_svc_async_exit() was called
before client devices were unregistered. This created a race window
where child devices could still be issuing service requests through
the async channels after the async infrastructure had already been
torn down.

Unregister client devices before tearing down the async threads and
channels to ensure all in-flight service calls drain before the
underlying infrastructure is destroyed.

Define INTEL_SIP_SMC_STATUS_NO_RESPONSE (0x3) and handle it in
stratix10_svc_async_poll() the same way as INTEL_SIP_SMC_STATUS_BUSY,

a hard failure.

When the Secure Device Manager has not yet produced a response for an
asynchronous transaction, ATF is expected to return
INTEL_SIP_SMC_STATUS_NO_RESPONSE. Without this handling, the service
layer maps the status to -EINVAL and async clients cannot distinguish
"not ready yet" from a real error.

Pushpendra SinghandSudeep Holla a4447c0693 firmware: arm_scmi: Rate-limit queue-full warnings in IRQ context
The scmi_notify() function is called from interrupt context to queue
received notification events onto a per-protocol kfifo. When the kfifo
is full, it logs a warning via dev_warn() for every dropped event.

Under conditions where the platform sends a burst of SCMI notifications
faster than the deferred worker can drain the queue, this results in a
flood of dev_warn() calls from IRQ context. Each call acquires the
console lock and may execute blocking console writes, causing the CPU
to be held in interrupt context for an extended period and leading to
observable system stalls.

Fix this by switching to dev_warn_ratelimited() to limit the frequency
of log messages when the notification queue is full. This reduces
console overhead in interrupt context and prevents CPU stalls caused by
excessive logging, while still preserving diagnostic visibility.

Steve DunnaganandSudeep Holla bf1deecccf firmware: arm_scmi: Use 64-bit division for clock rate rounding
SCMI clock range descriptors report rates as 64-bit values. When handling
a range clock, scmi_clock_determine_rate() rounds the requested rate up to
the next supported step using the SCMI RATE_STEP value.

The current code uses div64_ul() for this calculation. Since div64_ul()
takes an unsigned long divisor, the 64-bit RATE_STEP value can be truncated
on 32-bit builds. In the worst case, a non-zero 64-bit step can be narrowed
to zero before the division.

Store RATE_STEP in a u64, reject a malformed zero step, and use
DIV64_U64_ROUND_UP() so the divisor is handled as a 64-bit value.

This does not change behavior for valid firmware reporting a non-zero step
that fits in unsigned long.

Tested on Xunlong Orange Pi 5 Plus / RK3588 with SCMI over SMC. SCMI
clocks probed successfully before and after the change. SCMI-backed CPU
clocks were exercised through cpufreq-dt by switching each CPU policy
between its lowest and highest available OPP.

   while reserved has an offset of 24.
   Instead of zeroing fields, memset the struct to zero first based on

2) Make sure there is enough size to write constituents.

Seth ForsheeandSudeep Holla 53716a4d74 firmware: arm_ffa: Respect firmware advertised RX/TX buffer size limits
FFA_FEATURES reports the minimum size and alignment boundary required
for RXTX_MAP. In FF-A v1.2 and later it can also report a maximum buffer
size, with zero meaning that no maximum is enforced.

The driver only used the minimum value and then rounded it up to PAGE_SIZE
before invoking RXTX_MAP after commit 83210251fd ("firmware: arm_ffa:
Use the correct buffer size during RXTX_MAP"). On systems where PAGE_SIZE
is larger than the advertised minimum, this can exceed a non-zero maximum
reported by firmware. Older implementations do not advertise a maximum and
may also reject the rounded-up size.

Decode the maximum size and clamp the page-aligned minimum to it when it
is present. If no maximum is advertised and RXTX_MAP rejects the rounded
size with INVALID_PARAMETERS, retry with the advertised minimum size.
Record drv_info->rxtx_bufsz only after RXTX_MAP succeeds so it reflects
the size registered with firmware.

While there, also update RXTX_MAP_MIN_BUFSZ() to use FIELD_GET() for
consistency.

Linus Torvalds 9d0d4d12e4 Merge tag 'rproc-v7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux
Pull remoteproc updates from Bjorn Andersson:

 - Add i.MX94 support to the i.MX remoteproc driver, covering the
   Cortex-M7 and Cortex-M33 Sync cores. This also fixes programming of
   non-zero System Manager CPU/LMM reset vectors.

 - Move the remoteproc resource table definitions to a separate header,
   so they can be used by clients that do not otherwise depend on
   remoteproc. Switch the firmware resource handling over to the common
   iterator.

 - Update the Xilinx R5F remoteproc driver to check the remote core
   state before attaching, drop a binding header dependency, and add
   firmware-name based auto boot support.

 - Add Qualcomm Hawi ADSP/CDSP bindings, together with Shikra RPM
   bindings and CDSP, LPAICP, and MPSS PAS support. Fix a Qualcomm
   minidump leak, clean up PAS and WCSS reset handling, and make the
   user-visible Qualcomm naming consistent.

 - Remove a duplicate STM32_RPROC Kconfig dependency and make i.MX
   remoteproc instances use the device node name so multiple processors
   can be distinguished in sysfs.
