Because HVC uses the same interface for consoles and tty, and that resulted in dropped characters if the client driver returns EAGAIN because it's output buffer is full. I posted a patch that "fixes" this, but it was rejected. Here's the original patch: http://lists.ozlabs.org/pipermail/linuxppc-dev/2010-August/085136.html And here's the thread discussing our concerns: http://lists.ozlabs.org/pipermail/linuxppc-dev/2010-September/thread.html (search for "fix dropping of characters when output byte channel is full") -- Timur Tabi Linux kernel developer at Freescale -- To unsubscribe from this list: send the line "unsubscribe linux-console" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
