2024-09-05iio: adc: standardize on formatting for id match tablesJonathan Cameron64-169/+169
This is a frequent minor comment in reviews, so start cleaning up existing drivers in the hope we get fewer cases of cut and paste. There are not kernel wide rules for these, but for IIO the style that I prefer (and hence most common) is: - Space after { and before } - No comma after terminator { } This may cause merge conflicts but they should be trivial to resolve hence I have not broken this into per driver patches.

2024-09-03iio: imu: st_lsm6dsx: Remove useless dev_fwnode() callsAndy Shevchenko1-17/+6
The device property APIs designed that way that they will return an error when there is no valid fwnode provided. Moreover, the check for NULL of dev_fwnode() is not fully correct as in some (currently rare) cases it may contain an error pointer. This is not a problem anyway (see keyword 'valid' above) that's why the code works properly even without this change.

2024-09-03iio: adc: mcp320x: Drop vendorless compatible stringsRob Herring (Arm)1-10/+0
The vendorless compatible strings are deprecated and weren't retained when the binding was converted to schema. As a result, they are listed as undocumented when running "make dt_compatible_check". Rather than add them back to the schema, let's just drop them as they are unnecessary. Furthermore, they are unnecessary as the SPI matching will strip the vendor prefix on compatible string and match that against the spi_device_id table.

Perf currently errors out if it sees a newer packet version so instead of bumping it, add a new minor version field. This can be used to signify new versions that have backwards compatible fields.

2024-08-20coresight: Remove pending trace ID release mechanismJames Clark3-75/+41
Pending the release of IDs was a way of managing concurrent sysfs and Perf sessions in a single global ID map. Perf may have finished while sysfs hadn't, and Perf shouldn't release the IDs in use by sysfs and vice versa. Now that Perf uses its own exclusive ID maps, pending release doesn't result in any different behavior than just releasing all IDs when the last Perf session finishes. As part of the per-sink trace ID change, we would have still had to make the pending mechanism work on a per-sink basis, due to the overlapping ID allocations, so instead of making that more complicated, just remove it.

2024-08-20coresight: Use per-sink trace ID maps for Perf sessionsJames Clark8-17/+38
This will allow sessions with more than CORESIGHT_TRACE_IDS_MAX ETMs as long as there are fewer than that many ETMs connected to each sink. Each sink owns its own trace ID map, and any Perf session connecting to that sink will allocate from it, even if the sink is currently in use by other users. This is similar to the existing behavior where the dynamic trace IDs are constant as long as there is any concurrent Perf session active. It's not completely optimal because slightly more IDs will be used than necessary, but the optimal solution involves tracking the PIDs of each session and allocating ID maps based on the session owner. This is difficult to do with the combination of per-thread and per-cpu modes and some scheduling issues. The complexity of this isn't likely to worth it because even with multiple users they'd just see a difference in the ordering of ID allocations rather than hitting any limits (unless the hardware does have too many ETMs connected to one sink).

The global CPU ID mappings won't work for per-sink ID maps so move it to the ID map struct. coresight_trace_id_release_all_pending() is hard coded to operate on the default map, but once Perf sessions use their own maps the pending release mechanism will be deleted.

2024-08-20coresight: Clarify comments around the PID of the sink ownerJames Clark2-4/+6
"Process being monitored" and "pid of the process to monitor" imply that this would be the same PID if there were two sessions targeting the same process. But this is actually the PID of the process that did the Perf event open call, rather than the target of the session. So update the comments to make this clearer.
