fpga: dfl: fme: Fix cpu hotplug issue in performance reporting

2021-07-27T18:05:16+00:00

The performance reporting driver added cpu hotplug
feature but it didn't add pmu migration call in cpu
offline function.
This can create an issue incase the current designated
cpu being used to collect fme pmu data got offline,
as based on current code we are not migrating fme pmu to
new target cpu. Because of that perf will still try to
fetch data from that offline cpu and hence we will not
get counter data.

Patch fixed this issue by adding pmu_migrate_context call
in fme_perf_offline_cpu function.

fpga: stratix10-soc: Add missing fpga_mgr_free() call

2021-06-15T07:28:15+00:00

The stratix10-soc driver uses fpga_mgr_create() function and is therefore
responsible to call fpga_mgr_free() to release the class driver resources.
Add a missing call to fpga_mgr_free in the s10_remove() function.
