      Add and use remaining #defines for PCI device IDs (Stuart Brady) · a770dc7e
      由 aliguori 提交于 
      This patch adds and uses #defines for the remaining hardcoded PCI
device IDs.  It also moves definitions taken from linux/pci_ids.h
into a separate header (hw/pci_ids.h), removes the 'RTL' from
PCI_DEVICE_ID_REALTEK_RTL8029, and renames PCI_DEVICE_ID_FSL_E500
to PCI_DEVICE_ID_MPC8533E to match Linux's definition.

Changes in v2:
 * Don't use C99-style comments
 * Move definitions from linux/pci_ids.h into a separate header
 * Rename PCI_DEVICE_ID_FSL_E500 to PCI_DEVICE_ID_MPC8533E

      remove is_graphic_console from vga.c (Stefano Stabellini) · b8c18e4c
      由 aliguori 提交于 
      Hi all,
since vga_draw_graphic is only called by vga_hw_update when the console
associated with the graphic card is active, we don't need to check if
the current console is active using is_graphic_console.

I suspect I introduced these checks when the console switching mechanism
didn't work as it does now.

      DisplayAllocator interface (Stefano Stabellini) · 7b5d76da
      由 aliguori 提交于 
      Hi all,
this patch adds a DisplayAllocator interface that allows display
frontends (sdl in particular) to provide a preallocated display buffer
for the graphical backend to use.

Whenever a graphical backend cannot use
qemu_create_displaysurface_from because its own internal pixel format
cannot be exported directly (text mode or graphical mode with color
depth 8 or 24), it creates another display buffer in memory using
qemu_create_displaysurface and does the conversion.
This new buffer needs to be blitted into the sdl surface buffer every time
we need to update portions of the screen.
We can avoid this using the DisplayAllocator interace: sdl provides its
own implementation of qemu_create_displaysurface, giving back the sdl
surface buffer directly (as we used to do before the DisplayState
changes).
Since the buffer returned by sdl could be in bgr format we need to put
back in the handlers of that case.

This approach is good if the two following conditions are true:

1) the sdl surface is a software surface that resides in main memory;

2) the host display color depth is either 16 or 32 bpp.

If first condition is false we can have bad performances using sdl
and vnc together.
If the second condition is false performances are certainly not going to
improve but they shouldn't get worse either.

The first condition is always true, at least on linux/X11 systems; but I
believe is true also on other platforms.
The second condition is true in the vast majority of the cases.

This patch should also have the good side effect of solving the sdl
2D slowness malc was reporting on MacOS, because SDL_BlitSurface is not
going to be called anymore when the guest is in text mode or 24bpp.
However the root problem is still present so I suspect we may
still see some slowness on MacOS when the guest is in 32 or 16 bpp.

      Add specialized block driver scsi generic API (Avi Kivity) · 7d780669
      由 aliguori 提交于 
      When a scsi device is backed by a scsi generic device instead of an
ordinary host block device, the block API is abused in a couple of annoying
ways:

 - nb_sectors is negative, and specifies a byte count instead of a sector count
 - offset is ignored, since scsi-generic is essentially a packet protocol

This overloading makes hacking the block layer difficult.  Remove it by
introducing a new explicit API for scsi-generic devices.  The new API
is still backed by the old implementation, but at least the users are
insulated.

      monitor: Rework API (Jan Kiszka) · 376253ec
      由 aliguori 提交于 
      Refactor the monitor API and prepare it for decoupled terminals:
term_print functions are renamed to monitor_* and all monitor services
gain a new parameter (mon) that will once refer to the monitor instance
the output is supposed to appear on. However, the argument remains
unused for now. All monitor command callbacks are also extended by a mon
parameter so that command handlers are able to pass an appropriate
reference to monitor output services.

For the case that monitor outputs so far happen without clearly
identifiable context, the global variable cur_mon is introduced that
shall once provide a pointer either to the current active monitor (while
processing commands) or to the default one. On the mid or long term,
those use case will be obsoleted so that this variable can be removed
again.

Due to the broad usage of the monitor interface, this patch mostly deals
with converting users of the monitor API. A few of them are already
extended to pass 'mon' from the command handler further down to internal
functions that invoke monitor_printf.

At this chance, monitor-related prototypes are moved from console.h to
a new monitor.h. The same is done for the readline API.

      monitor: Rework modal password input (Jan Kiszka) · bb5fc20f
      由 aliguori 提交于 
      Currently, waiting for the user to type in some password blocks the
whole VM because monitor_readline starts its own I/O loop. And this loop
also screws up reading passwords from virtual console.

Patch below fixes the shortcomings by using normal I/O processing also
for waiting on a password. To keep to modal property for the monitor
terminal, the command handler is temporarily replaced by a password
handler and a callback infrastructure is established to process the
result before switching back to command mode.

      monitor: Rework early disk password inquiry (Jan Kiszka) · c0f4ce77
      由 aliguori 提交于 
      Reading the passwords for encrypted hard disks during early startup is
broken (I guess for quiet a while now):
 - No monitor terminal is ready for input at this point
 - Forcing all mux'ed terminals into monitor mode can confuse other
   users of that channels

To overcome these issues and to lay the ground for a clean decoupling of
monitor terminals, this patch changes the initial password inquiry as
follows:
 - Prevent autostart if there is some encrypted disk
 - Once the user tries to resume the VM, prompt for all missing
   passwords
 - Only resume if all passwords were accepted
