2020-06-10	vmbus: vmbus implementation	Jon Doron
	Add the VMBus infrastructure -- bus, devices, root bridge, vmbus state machine, vmbus channel interactions, etc. VMBus is a collection of technologies. At its lowest layer, it's a message passing and signaling mechanism, allowing efficient passing of messages to and from guest VMs. A layer higher, it's a mechanism for defining channels of communication, where each channel is tagged with a type (which implies a protocol) and a instance ID. A layer higher than that, it's a bus driver, serving as the basis of device enumeration within a VM, where a channel can optionally be exposed as a paravirtual device. When a server-side (paravirtual back-end) component wishes to offer a channel to a guest VM, it does so by specifying a channel type, a mode, and an instance ID. VMBus then exposes this in the guest. More information about VMBus can be found in the file vmbuskernelmodeclientlibapi.h in Microsoft's WDK. TODO: - split into smaller palatable pieces - more comments - check and handle corner cases Kudos to Evgeny Yakovlev (formerly eyakovlev@virtuozzo.com) and Andrey Smetatin (formerly asmetanin@virtuozzo.com) for research and prototyping.

2019-03-07	kconfig: introduce kconfig files	Paolo Bonzini
	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.
