The SHM bridge makes the Qualcomm RB3 and SM8150-HDK reset while probing
the RMTFS (in qcom_scm_assign_mem()). Blacklist the SHM Bridge on
corresponding platforms using SoC-level compat string. If later it's
found that the bad behaviour is limited just to the particular boards
rather than SoC, the compat strings can be adjusted.

When using /proc/interrupts to collect statistics on smp2p interrupt
counts, it is hard to distinguish the different instances of smp2p from
each other. For example to debug a processor boot issue, the ready and
handover interrupts are checked for sanity to ensure the firmware
reached a specific initialization stage.
Remove "smp2p" string from the irq request so that the irq will default
to the device name. Add an .irq_print_chip() callback to print the irq
chip name as the device name. These two changes allow for a unique name
to be used in /proc/interrupts as shown below.
/ # cat /proc/interrupts | grep smp2p
18: ... ipcc 196610 Edge smp2p-adsp
20: ... ipcc 131074 Edge smp2p-modem

The multiple BWMONv4 instances available on the X1E80100 SoC use the
same interrupt number. Mark them are shared to allow for re-use across
instances.
Using IRQF_SHARED coupled with devm_request_threaded_irq implies that
the irq can still trigger during/after bwmon_remove due to other active
bwmon instances. Handle this race by relying on bwmon_disable to disable
the interrupt and coupled with explicit request/free irqs.

drivers-for-6.11
Merge the in-kernel protection-domain mapper implementation through a
feature branch, to allow sharing with the remoteproc tree.
|
|
Existing userspace protection domain mapper implementation has several
issue. It doesn't play well with CONFIG_EXTRA_FIRMWARE, it doesn't
reread JSON files if firmware location is changed (or if firmware was
not available at the time pd-mapper was started but the corresponding
directory is mounted later), etc.
Provide in-kernel service implementing protection domain mapping
required to work with several services, which are provided by the DSP
firmware.
This module is loaded automatically by the remoteproc drivers when
necessary via the symbol dependency. It uses a root node to match a
protection domains map for a particular board. It is not possible to
implement it as a 'driver' as there is no corresponding device.

SHM Bridge is a safety mechanism allowing to limit the amount of memory
shared between the kernel and the TrustZone to regions explicitly marked
as such.
Add a variant of the tzmem allocator that configures the memory pools as
SHM bridges. It also enables the SHM bridge globally so non-SHM bridge
memory will no longer work with SCM calls.
If enabled at build-time, it will still be checked for availability at
run-time. If the architecture doesn't support SHM Bridge, the allocator
will fall back to the generic mode.

Select the TrustZone memory allocator in Kconfig and create a pool of
memory shareable with the TrustZone when probing the SCM driver.
This will allow a gradual conversion of all relevant SCM calls to using
the dedicated allocator.
The policy used for the pool is "on-demand" and the initial size is 0
as - depending on the config - it's possible that no SCM calls needing
to allocate memory will be called. The sizes of possible allocations also
vary substiantially further warranting the "on-demand" approach.

We have several SCM calls that require passing buffers to the TrustZone
on top of the SMC core which allocates memory for calls that require
more than 4 arguments.
Currently every user does their own thing which leads to code
duplication. Many users call dma_alloc_coherent() for every call which
is terribly unperformant (speed- and size-wise).
Provide a set of library functions for creating and managing pools of
memory which is suitable for sharing with the TrustZone, that is:
page-aligned, contiguous and non-cachable as well as provides a way of
mapping of kernel virtual addresses to physical space.
Make the allocator ready for extending with additional modes of operation
which will allow us to support the SHM bridge safety mechanism once all
users convert.
