ide: model HOB correctly

I have been staring at this FIXME for years and I never knew what it
meant. I finally stumbled across it!

When writing to the command registers, the old value is shifted into a
HOB copy of the register and the new value is written into the primary
register. When reading registers, the value retrieved is dependent on
the HOB bit in the CONTROL register.

By setting bit 7 (0x80) in CONTROL, any register read will, if it has
one, yield the HOB value for that register instead.

Our code has a problem: We were using bit 7 of the DEVICE register to
model this. We use bus->cmd roughly as the control register already, as
it stores the value from ide_ctrl_write.

Lastly, all command register writes reset the HOB, so fix that, too.

migration.

Switch to creating kvmclock QEMU device unconditionally, it seems

7 months agochar: fix logging when chardev write fails
Daniel P. Berrangé [Mon, 14 Sep 2020 10:31:09 +0000 (12:31 +0200)] 
char: fix logging when chardev write fails

The qemu_chr_write_buffer() method sends data to the chardev backend for
writing, and then also writes to the log file. In case the chardev
backend only writes part of the data buffer, we need to make sure we
only log the same subset. qemu_chr_write_buffer() will be invoked again
later to write the rest of the buffer.

In the case the chardev backend returns an error though, no further
attempts to likely to be made to write the data. We must therefore write
the entire buffer to the log immediately.

An example where this is important is with the socket backend. This will
return -1 for all writes if no client is currently connected. We still
wish to write data to the log file when no client is present though.
This used to work because the chardev would return "len" to pretend it
had written all data when no client is connected, but this changed to
return an error in

  commit 271094474b65de1ad7aaf729938de3d9b9d0d36f
  Author: Dima Stepanov <dimastep@yandex-team.ru>
  Date: Thu May 28 12:11:18 2020 +0300

    char-socket: return -1 in case of disconnect during tcp_chr_write

and this broke the logging, resulting in all data being discarded when
no client is present.
