Peter Maydell 4fbf55568b hw/pl110: Model the PL111 CLCD controller
Model the PL111 CLCD controller. This is a minor variation
on the PL110; the major programmer visible differences are
support for hardware cursor (unimplemented) and two new
pixel formats.

Since syborg_fb.c borrows the pl11x pixel drawing routines,
we also update it to cope with the new slightly larger array
of function pointers.

Paolo Bonzini 8b2a04eeb9 scsi: do not overwrite memory on REQUEST SENSE commands with a large buffer
Other scsi_target_reqops commands were careful about not using r->cmd.xfer
directly, and instead always cap it to a fixed length.  This was not done
for REQUEST SENSE, and this patch fixes it.

Paolo Bonzini c39ce112b6 scsi: pass cdb already to scsi_req_new
Right now the CDB is not passed to the SCSIBus until scsi_req_enqueue.
Passing it to scsi_req_new will let scsi_req_new dispatch common requests
through different reqops.

Moving the memcpy to scsi_req_new is a hack that will go away as
soon as scsi_req_new will also take care of the parsing.

Paolo Bonzini b45ef674f4 scsi: move sense handling to generic code
With this patch, sense data is stored in the generic data structures
for SCSI devices and requests.  The SCSI layer takes care of storing
sense data in the SCSIDevice for the subsequent REQUEST SENSE command.

At the same time, get_sense is removed and scsi_req_get_sense can use
an entirely generic implementation.

Paolo Bonzini 05751d3ff7 vscsi: always use get_sense
vscsi supports autosensing by providing sense data directly in the
response.  When get_sense was added, the older state machine approach
that sent REQUEST SENSE commands separately was left in place.  Remove
it, all existing SCSIDevices do support autosensing and the next patches
will make the support come for free from the SCSIBus.

Paolo Bonzini e44089c79d scsi-disk: no need to call scsi_req_data on a short read
In fact, if the HBA's transfer_data callback goes on with scsi_req_continue
the request will be completed successfully instead of showing a failure.
It can even cause a segmentation fault.

An easy way to trigger it is "eject -f cd" during installation (during media
test if the installer does something like that).

Anthony Liguori 4333979e3d pc: make vgabios exit port more useful
We've always listened on port 501 for vgabios panic messages.  In the entire
time I've worked on QEMU, I've never actually seen a vgabios panic message :-)

If we change the semantics of this port a little bit, it makes it possible to
use it for more interesting use-cases.  I chose this approach instead of adding
a new I/O port because it avoids having a guest visible change.

This change allows single-byte access to port 501 and also uses the value
written to construct an exit code.

Gerd Hoffmann 21635e121a usb/hid: add hid_pointer_activate, use it
HID reorganziation broke the usb tablet in windows xp.  The reason is
that xp activates idle before it starts polling, which creates a
chicken-and-egg issue:  We don't call hid_pointer_poll because there are
no pending events.  We don't get any events because the activation code
in hid_pointer_poll is never executed and thus all pointer events are
routed to the PS/2 mouse by qemu.

Fix this by creating a hid_pointer_activate function and call it from
usb-hid when the guest sets the idle state.
