Subject: [PATCH 0/5] cxl/hdm: Decoder enumeration fixes
Date: Fri, 14 Apr 2023 11:53:49 -0700 [thread overview]
Message-ID: <168149842935.792294.13212627946146993066.stgit@dwillia2-xfh.jf.intel.com> (raw)
While testing region autodetect with physical hardware a few fixes fell
out. The most interesting being evidence that a device is sensitive to
8-byte reads of 2 consecutive 4-byte registers. The other is a long
reported issue by Jonathan on how "passthrough" decoders are detected,
and having an example with physical hardware to reinforce the
observation from QEMU.
The rest are ancillary fixes and new debug messages.

Dan Williams (5):
cxl/hdm: Fail upon detecting 0-sized decoders
cxl/hdm: Use 4-byte reads to retrieve HDM decoder base+limit
cxl/core: Drop unused io-64-nonatomic-lo-hi.h
cxl/port: Scan single-target ports for decoders
cxl/hdm: Add more HDM decoder debug messages at startup
