(Rusty, would it improve the chances of getting this patch in your tree if this description were written with latex instead of without it?) Here is a new iteration of the patch series that implements a transport for guest and host communications. I've tested for compatibility (old qemu & new kernel, new qemu & old kernel, new qemu & new kernel) and it all works fine. To maintain backward compatibility, the first port to be spawned (port at id 0) is to be a console port, to be bound to hvc. This keeps new host, old guest happy. A testsuite is put up at the following site that has an interactive test program that can be run in the guest. It also has an automated test suite that tests the major functionalities presented here: http://fedorapeople.org/gitweb?p=amitshah/public_git/test-virtserial.git This version passes all the automated tests there. Christian has tested the console functionality on s390. v10: - only one process can open a port in the guest - minor fixes for throttling and caching cases Please review and apply, Amit Amit Shah (1): virtio_console: Add support for multiple ports for generic guest and host communication drivers/char/Kconfig | 6 + drivers/char/virtio_console.c | 1412 ++++++++++++++++++++++++++++++++++++---- include/linux/virtio_console.h | 50 ++- 3 files changed, 1332 insertions(+), 136 deletions(-) _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/virtualization
