-Subject: [PATCH 02/12] chardev: connect socket to a spawned command
-
-The command is started in a shell (sh -c) with stdin connect to QEMU
-via a Unix domain stream socket. QEMU then exchanges data via its own
-end of the socket, just like it normally does.
-
-"-chardev socket" supports some ways of connecting via protocols like
-telnet, but that is only a subset of the functionality supported by
-tools socat. To use socat instead, for example to connect via a socks
-proxy, use:
-
-  -chardev 'socket,id=socat,cmd=exec socat FD:0 SOCKS4A:socks-proxy.localdomain:example.com:9999,,socksuser=nobody' \
-  -device usb-serial,chardev=socat
-
-Beware that commas in the command must be escaped as double commas.
-
-Or interactively in the console:
-   (qemu) chardev-add socket,id=cat,cmd=cat
-   (qemu) device_add usb-serial,chardev=cat
-   ^ac
-   # cat >/dev/ttyUSB0
-   hello
-   hello
-
-Another usage is starting swtpm from inside QEMU. swtpm will
-automatically shut down once it looses the connection to the parent
-QEMU, so there is no risk of lingering processes:
-
-  -chardev 'socket,id=chrtpm0,cmd=exec swtpm socket --terminate --ctrl type=unixio,,clientfd=0 --tpmstate dir=... --log file=swtpm.log' \
-  -tpmdev emulator,id=tpm0,chardev=chrtpm0 \
-  -device tpm-tis,tpmdev=tpm0
-
-The patch was discussed upstream, but QEMU developers believe that the
-code calling QEMU should be responsible for managing additional
-processes. In OE-core, that would imply enhancing runqemu and
-oeqa. This patch is a simpler solution.
-
-Because it is not going upstream, the patch was written so that it is
-as simple as possible.
-
-Upstream-Status: Inappropriate [embedded specific]
