[HACK QEMU PATCH v1 0/1] CXL MCTP FMAPI Binding Fix for MCTP over i2c/USB

Posted by anisa.su887@gmail.com 4 months, 3 weeks ago

From: Anisa Su <anisa.su@samsung.com>

The FMAPI DCD Management patchset (https://lore.kernel.org/linux-cxl/20250626222743.1766404-1-anisa.su887@gmail.com/T/#t)
is based on upstream, which does not include the i2c MCTP hack or the new MCTP
USB support carried in Jonathan's tree.

The commands are accessible upstream through a switch-cci. Thus, to break the
dependence on the MCTP support patches, the commands are sent separately
from this patch.

This patch is based on Jonathan's latest branch
(https://gitlab.com/jic23/qemu/-/tree/cxl-2025-06-10) and fixes the if condition in
i2c_mctp_cxl.c and dev-mctp.c to allow FMAPI DCD commands to be processed.

For more info, refer to previous thread from v2 of the FMAPI DCD patchset:
