kconfig: introduce kconfig files The Kconfig files were generated mostly with this script: for i in `grep -ho CONFIG_[A-Z0-9_]* default-configs/* \| sort -u`; do set fnord `git grep -lw $i -- 'hw//Makefile.objs' ` shift if test $# = 1; then cat >> $(dirname $1)/Kconfig << EOF config ${i#CONFIG_} bool EOF git add $(dirname $1)/Kconfig else echo $i $ fi done sed -i '$d' hw//Kconfig for i in hw/; do if test -d $i && ! test -f $i/Kconfig; then touch $i/Kconfig git add $i/Kconfig fi done Whenever a symbol is referenced from multiple subdirectories, the script prints the list of directories that reference the symbol. These symbols have to be added manually to the Kconfig files. Kconfig.host and hw/Kconfig were created manually.

ppc64: Express dependencies of 'pseries' and 'powernv' machines with kconfig The POWERNV switch should always select ISA_IPMI_BT, then the other IPMI options are turned on automatically now. CONFIG_DIMM should always be selected by the pseries machine, which in turn depends on CONFIG_MEM_DEVICE since DIMM implements this interface. CONFIG_VIRTIO_VGA can be dropped from default-configs/ppc64-softmmu.mak completely since this device is already automatically enabled via hw/display/Kconfig now.

hw/cxl/device: Add a memory device (8.2.8.5) A CXL memory device (AKA Type 3) is a CXL component that contains some combination of volatile and persistent memory. It also implements the previously defined mailbox interface as well as the memory device firmware interface. Although the memory device is configured like a normal PCIe device, the memory traffic is on an entirely separate bus conceptually (using the same physical wires as PCIe, but different protocol). Once the CXL topology is fully configure and address decoders committed, the guest physical address for the memory device is part of a larger window which is owned by the platform. The creation of these windows is later in this series. The following example will create a 256M device in a 512M window: -object "memory-backend-file,id=cxl-mem1,share,mem-path=cxl-type3,size=512M" -device "cxl-type3,bus=rp0,memdev=cxl-mem1,id=cxl-pmem0" Note: Dropped PCDIMM info interfaces for now. They can be added if appropriate at a later date.
