Hello,

I am running qemu-system-x86_64

qemu-system-x86_64 --version
QEMU emulator version 8.0.92 (v8.1.0-rc2-80-g0450cf0897)

qemu-system-x86_64 \
-m 2G,slots=4,maxmem=4G \
-smp 4 \
-machine type=q35,accel=kvm,cxl=on \
-enable-kvm \
-nographic \
-device pxb-cxl,id=cxl.0,bus=pcie.0,bus_nr=52 \
-device cxl-rp,id=rp0,bus=cxl.0,chassis=0,port=0,slot=0 \
-object memory-backend-file,id=mem0,mem-path=/tmp/mem0,size=1G,share=true \
-device cxl-type3,bus=rp0,volatile-memdev=mem0,id=cxl-mem0 \
-M cxl-fmw.0.targets.0=cxl.0,cxl-fmw.0.size=1G


I was expecting the CXL memory to be listed in "System Ram", the lsmem
shows only 2G memory which is System RAM, it's not listing the CXL
memory.

Do I need to pass any particular parameter in the kernel command line?

Is there any documentation available? I followed the inputs provided in

https://lore.kernel.org/linux-mm/y+csoehvlkudn...@kroah.com/T/

Is there any documentation/blog listed?
