Subject: Re: [PATCH qemu v1 7/8] hw/cxl: Wire SVC and Dev3 capabilities to CXL Type 3 device
Date: Wed,  4 Nov 2026 11:25:27 -0600	[thread overview]
Message-ID: <20261104172527.2172366-4-junjie.cao@linux.dev> (raw)
In-Reply-To: <331418503.141793792283935.JavaMail.epsvc@epcpadp2new>

Tested Type-3 capability enumeration and UIO/SVC/flit dependency
combinations at cold boot and after system reset on q35, with the
full series on 3c99db7705c1.

Linux UIO discovery and a 1-way UIO region commit also passed with
Davidlohr's pcie-uio-rfc kernel [1]. For that kernel's UIO checks,
QEMU used hdm-db=on and CFMWS restrictions=0x2d; the guest kernel
enabled CONFIG_CXL_REGION_INVALIDATION_TEST to allow region setup
in the VM.
