Subject: [PATCH 0/2] coresight: ultrasoc: Add support for System Memory Buffer device
Date: Mon, 19 Jul 2021 19:17:35 +0800 [thread overview]
Message-ID: <20210719111737.47891-1-liuqi115@huawei.com> (raw)
This patchset add support for SMB(System Memory Buffer) device, SMB
obtains CPU instructions from Coresight ETM device and stores these
messages in system memory.
SMB is developed by Ultrasoc technology, which is acquired by Siemens,
and we still use "Ultrasoc" to name document and driver.
Change since RFC:
- Move ultrasoc driver to drivers/hwtracing/coresight.
- Remove ultrasoc-axi-com.c, as AXI-COM doesn't need to be configured in
basic tracing function.
- Remove ultrasoc.c as SMB does not need to register with the ultrasoc core.
- Address the comments from Mathieu and Suzuki.
