[PATCH 07/19] hw/misc/bcm2835_mbox: Add trace events |
Date: |
Thu, 26 Sep 2019 19:34:15 +0200 |
Add trace events for read/write accesses and IRQ.
Properties are structures used for the ARM particular MBOX.
Since one call in bcm2835_property.c concerns the mbox block,
name this trace event in the same bcm2835_mbox* namespace.
