Subject: [GIT PULL] Compute Express Link (CXL) for 6.10
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 7bit

Hi Linus, please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl.git tags/cxl-for-6.10

..to receive 3 feature updates and some fixes and cleanups for CXL.

Three CXL mailbox passthrough commands are added to support the populating and clearing
of vendor debug logs.

The second feature is adding support of Device Phyiscal Address (DPA) to Host Physical
Address (HPA) translation for CXL events of cxl_dram and cxl_general media. The support
allows user space to figure out which CXL region the event occured via trace event.

The third feature connects CXL to CPER reporting. If a device is configured for firmware
first, CXL event records are not sent directly to the host. Those records are reported
through EFI Common Platform Error Records (CPER). Support is added to route the CPER
records through the CXL sub-system in order to provide DPA to HPA translation and also
event decoding and tracing. This is useful for users to determine which system issues
may correspond to specific hardware events.

A number of misc cleanups and fixes are also included in this pull request.

The following commits have late tags that were submitted after the commits have been
pushed to cxl/next branch:
