It updates input word in the same way. For the moment it works well while we don't mix serial port console with VGA console or virtio-console (there is a special case for VGA console that overwrite without condition the emit word, see 9b89b28 "Add support for qemu standard VGA". Im' working on this). You can test it with: qemu-system-ppc64 -nodefaults -nographic \ -chardev socket,id=serial_id_serial0,host=localhost,port=4441,telnet,server,wait \ -device spapr-vty,chardev=serial_id_serial0 \ -chardev socket,id=serial_id_serial1,host=localhost,port=4442,telnet,server,wait \ -device spapr-vty,chardev=serial_id_serial1 \ -monitor stdio Connect on the two ports with "telnet localhost 4441" and "telnet 4442". Once it is done you will see on the first console the SLOF logs. Then, in the first console: " /vdevice/vty@71000002" input Now what you write on second console is written on the first one. To send the characters to the second one, we should use: " /vdevice/vty@71000002" output but it doesn't work and this patch fixes that. A shortcut for these two commands is: " /vdevice/vty@71000002" io v5: - close previous ihandle in set-stdin and set-stdout v4: - use variables to store stdin and stdout ihandle (rename them) - introduce set-stdin and set-stdout - update error message v3: - code cleanup and re-order - store ihandle and xt handle for input too v2: - resolve ihandle and xt handle in the output command to speed up emit function milliseconds 2000 0 do 41 emit loop milliseconds swap - cr .d cr original: 770 v1: 4710 v2: 1721 Laurent Vivier (2): Fix output word resolve ihandle and xt handle in the input command (like for the output) slof/fs/term-io.fs | 122 ++++++++++++++++++++++++++++++++--------------------- 1 file changed, 74 insertions(+), 48 deletions(-)
