From: Sjur Br?ndeland <sjur.brandeland at stericsson.com> This reverts commit 8078db789a92b10ff6e2d713231b5367e014c53b. The reverted patch caused opening of ports to fail for rproc_serial. In probe guest_connected was set to true, but port_fops_open() fails with -EMFILE if guest_connected already is true. Signed-off-by: Sjur Br?ndeland <sjur.brandeland at stericsson.com> --- Hi Rusty, Here is a fix intended for 3.9. Sorry for the churn here :-( Regards, Sjur drivers/cha...

From: Sjur Br?ndeland <sjur.brandeland at stericsson.com> When rproc_serial is initialized, guest_connected should be set to true.

From: Sjur Br?ndeland <sjur.brandeland at stericsson.com> This patch-set introduces a new virtio type "rproc_serial" for communicating with remote processors over shared memory. The driver depends on the the remoteproc framework. As preparation for introducing "rproc_serial" I've done a refactoring of the transmit buffer handling. Changes since v7: - Rebased to virtio-next branch. - Removed...

From: Sjur Br?ndeland <sjur.brandeland at stericsson.com> I thought rebasing rproc_serial to linux-next was going to be trivial. But when starting the merge I realized that I had to refactor the the patches from Masami Hiramatsu. The splice support has the same issue as I faced, with different type of buffers in the out_vq. So I ended up refactoring the splice functionality. The code...

Rproc_serial communicates with remote processors that may crash and leave buffers in the out-queue. The virtio serial ports may have buffers in the out-queue as well, e.g. for non-blocking ports and the host didn't consume them yet.
