9 years agoqapi-types: add C99 index names to arrays
Michael S. Tsirkin [Thu, 19 Feb 2015 10:13:10 +0000 (11:13 +0100)]
qapi-types: add C99 index names to arrays

It's not easy to figure out how monitor translates
strings: most QEMU code deals with translated indexes,
these are translated using _lookup arrays,
so you need to find the array name, and find the
appropriate offset.

This patch adds C99 indexes to lookup arrays, which makes it possible to
find the correct key using simple grep, and see that the matching is
correct at a glance.

Example:

Before:

const char *MigrationCapability_lookup[] = {
    "xbzrle",
    "rdma-pin-all",
    "auto-converge",
    "zero-blocks",
    NULL,
};

After:

const char *MigrationCapability_lookup[] = {
    [MIGRATION_CAPABILITY_XBZRLE] = "xbzrle",
    [MIGRATION_CAPABILITY_RDMA_PIN_ALL] = "rdma-pin-all",
    [MIGRATION_CAPABILITY_AUTO_CONVERGE] = "auto-converge",
    [MIGRATION_CAPABILITY_ZERO_BLOCKS] = "zero-blocks",
    [MIGRATION_CAPABILITY_MAX] = NULL,
};

9 years agousb: Suppress bogus error when automatic usb-hub creation fails
Markus Armbruster [Wed, 4 Feb 2015 12:28:11 +0000 (13:28 +0100)]
usb: Suppress bogus error when automatic usb-hub creation fails

USBDevice's realize method usb_qdev_realize() automatically creates a
usb-hub when only one port is left.  Creating devices in realize
methods is questionable, but works.

If usb-hub creation fails, an error is reported to stderr, but the
failure is otherwise ignored.  We then create the actual device using
the last port, which may well succeed.

Example:

    $ qemu -nodefaults -S -display none -machine usb=on -monitor stdio
    QEMU 2.2.50 monitor - type 'help' for more information
    (qemu) device_add usb-mouse
    [Repeat 36 times]
    (qemu) info usb
      Device 0.0, Port 1, Speed 12 Mb/s, Product QEMU USB Mouse
      Device 0.0, Port 2, Speed 12 Mb/s, Product QEMU USB Hub
      Device 0.0, Port 2.1, Speed 12 Mb/s, Product QEMU USB Mouse
    [More mice and hubs omitted...]
      Device 0.0, Port 2.8.8.8.8.7, Speed 12 Mb/s, Product QEMU USB Mouse
    (qemu) device_add usb-mouse
    usb hub chain too deep
    Failed to initialize USB device 'usb-hub'
    (qemu) info usb
    [...]
      Device 0.0, Port 2.8.8.8.8.7, Speed 12 Mb/s, Product QEMU USB Mouse
      Device 0.0, Port 2.8.8.8.8.8, Speed 12 Mb/s, Product QEMU USB Mouse

Despite the "Failed" message, the command actually succeeded.

In QMP, it's worse.  When adding the 37th mouse via QMP, the command
fails with

    {"error": {"class": "GenericError", "desc": "usb hub chain too deep"}}

Additionally, "Failed to initialize USB device 'usb-hub'" is reported
on stderr.  Despite the command failure, the device was created.  This
is wrong.

Fix by avoiding qdev_init() for usb-hub creation, so we can ignore
errors cleanly.

somewhat brittle.

usb_msd_init() and usb_bt_init() call qdev_init().  The latter
additionally reports an error when qdev_init() fails.

Realization failure produces multiple error reports: a specific one
from qdev_init(), and generic ones from usb_bt_init(),
usb_create_simple(), usbdevice_create() and usb_parse().

Remove realization from the usbdevice_init() methods.  Realize in

vhost-scsi: Improve error reporting for invalid vhostfd

another one from vhost_scsi_realize().  The second one gets suppressed
in QMP context.

That's because monitor_handle_fd_param() calls qerror_report_err().
Calling qerror_report_err() is always inappropriate in realize
methods, because it doesn't return the Error object.  It either
reports the error to stderr or the human monitor, or it stores it in
the QMP monitor, where it makes the QMP command fail even when the
realize method ignores the error and succeeds.  Fortunately,
vhost_scsi_realize() doesn't do that.

The command is not implemented correctly yet. The documentation allows
to not pass any value to set, in which case the time is re-read from
RTC. However, reading CMOS on Windows is not trivial to implement. So
instead of pretending we've set the correct time, fail explicitly.

qga: implement file commands for Windows guest

- guest_file_open
- guest_file_close
- guest_file_write
- guest_file_read
- guest_file_seek
- guest_file_flush

Motivation is quite simple: Windows guests should be supported with the
same set of features as Linux one. Also this patch is a prerequisite for
Windows guest-exec command support.
