hwtracing: hisi_ptt: Fix potential sleep in atomic context
We're using pci_irq_vector() to obtain the interrupt number and then
bind it to the CPU start perf under the protection of spinlock in
pmu::start(). pci_irq_vector() might sleep since [1] because it will
call msi_domain_get_virq() to get the MSI interrupt number and it
needs to acquire dev->msi.data->mutex. Getting a mutex will sleep on

coresight: dummy: Update type of mode parameter in dummy_{sink,source}_enable()

matches the expected type of the call and trapping if they do not match

to catch these issues at compile time, which reveals:
drivers/hwtracing/coresight/coresight-dummy.c:53:12: error: incompatible function pointer types initializing 'int (*)(struct coresight_device *, struct perf_event *, enum cs_mode)' with an expression of type 'int (struct coresight_device *, struct perf_event *, u32)' (aka 'int (struct coresight_device *, struct perf_event *, unsigned int)') [-Werror,-Wincompatible-function-pointer-types-strict]

2 errors generated.
Commit 9fa3682869d4 ("coresight: Use enum type for cs_mode wherever
possible") updated the type of the mode parameter in the prototype but
this driver was not introduced until commit 9d3ba0b6c056 ("Coresight:
Add coresight dummy driver") and 'int' is ABI compatible with 'enum
cs_mode', so there is no warning from regular
-Wincompatible-function-pointer-types.
Adjust the type of the mode parameter in the callback implementations in
the coresight dummy driver to match the prototype, clearing up the
warning and avoiding kCFI failures at runtime.
char: xilinx_hwicap: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() is renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.
char: xilinx_hwicap: Drop if block with always false condition
hwicap_drv_remove() is only called for a device after hwicap_drv_probe()
returned 0. In that case dev_set_drvdata() was called (by hwicap_setup())
with a non-NULL value and so dev_get_drvdata() won't return NULL.

misc: tps6594-esm: Add driver for TI TPS6594 ESM
This patch adds support for TPS6594 ESM (Error Signal Monitor).
This device monitors the SoC error output signal at its nERR_SOC input pin.
In error condition, ESM toggles its nRSTOUT_SOC pin to reset the SoC.

Coresight: Add coresight dummy driver

Coresight devices. The module may also be used to define components that

in the driver. It provides Coresight API for operations on dummy devices,

counter: i8254: Introduce the Intel 8254 interface library module
Exposes consumer library functions providing support for interfaces
compatible with the venerable Intel 8254 Programmable Interval Timer
(PIT).
The Intel 8254 PIT first appeared in the early 1980s and was used
initially in IBM PC compatibles. The popularity of the original Intel
825x family of chips led to many subsequent variants and clones of the
interface in various chips and integrated circuits. Although still
popular, interfaces compatible with the Intel 8254 PIT are nowdays
typically found embedded in larger VLSI processing chips and FPGA
components rather than as discrete ICs.
A CONFIG_I8254 Kconfig option is introduced by this patch. Modules
wanting access to these i8254 library functions should select this
Kconfig option, and import the I8254 symbol namespace.

matching to match the PIDR2:JEDEC, BIT[3], which must be 1 (RAO) always.

The Zynq platform has PCAP, ICAP and JTAG interfaces for configuring
programmable logic (PL). The existing driver implementation uses the
PCAP interface to configure the PL. Before switching the PL configuration
interface from PCAP to ICAP make sure that all outstanding Transactions
relevant to the PL configuration should be completed by the PCAP interface
otherwise it may lead to PL configuration issues.
This patch provides a required fix to ensure that all existing PL

coresight: Enable and disable helper devices adjacent to the path
Currently CATU is the only helper device, and its enable and disable
calls are hard coded. To allow more helper devices to be added in a
generic way, remove these hard coded calls and just enable and disable
all helper devices.
This has to apply to helpers adjacent to the path, because they will
never be in the path. CATU was already discovered in this way, so
there is no change there.
One change that is needed is for CATU to call back into ETR to allocate
the buffer. Because the enable call was previously hard coded, it was
done at a point where the buffer was already allocated, but this is no
longer the case.

coresight: Make refcount a property of the connection
This removes the need to do an additional lookup for the total number
of ports used and also removes the need to allocate an array of
refcounts which is just another representation of a connection array.
This was only used for link type devices, for regular devices a single
refcount on the coresight device is used.
There is a both an input and output refcount in case two link type
devices are connected together so that they don't overwrite each other's
counts.
James Clark [Tue, 25 Apr 2023 14:35:36 +0000 (15:35 +0100)]
coresight: Store in-connections as well as out-connections
This will allow CATU to get its associated ETR in a generic way where
currently the enable path has some hard coded searches which avoid
the need to store input connections.
This also means that the full search for connected devices on removal
can be replaced with a loop through only the input and output devices.

There is some duplication between coresight_fixup_device_conns() and

the fact that coresight_fixup_orphan_conns() can't handle iterating over

By making it able to handle fixing up it's own connections the other
function can be removed.

coresight: Dynamically add connections
Add a function for adding connections dynamically. This also removes
the 1:1 mapping between port number and the index into the connections
array. The only place this mapping was used was in the warning for
duplicate output ports, which has been replaced by a search. Other
uses of the port number already use the port member variable.
Being able to dynamically add connections will allow other devices like
CTI to re-use the connection mechanism despite not having explicit
connections described in the DT.
The connections array is now no longer sparse, so child_fwnode doesn't
need to be checked as all connections have a target node. Because the
array is no longer sparse, the high in and out port numbers are required
for the refcount arrays. But these will also be removed in a later
commit when the refcount is made a property of the connection.

coresight: Fix loss of connection info when a module is unloaded
child_fwnode should be a read only property based on the DT or ACPI. If
it's cleared on the parent device when a child is unloaded, then when
the child is loaded again the connection won't be remade.
child_dev should be cleared instead which signifies that the connection
should be remade when the child_fwnode registers a new coresight_device.
Similarly the reference count shouldn't be decremented as long as the
parent device exists. The correct place to drop the reference is in
coresight_release_platform_data() which is already done.
Reproducible on Juno with the following steps:
