66dc50f705 s390x: improve error handling for SSCH and RSCH
Simplify the error handling of the SSCH and RSCH handler avoiding
arbitrary and cryptic error codes being used to tell how the instruction
is supposed to end.  Let the code detecting the condition tell how it's
to be handled in a less ambiguous way.  It's best to handle SSCH and RSCH
in one go as the emulation of the two shares a lot of code.

For passthrough this change isn't pure refactoring, but changes the way
kernel reported EFAULT is handled. After clarifying the kernel interface
we decided that EFAULT shall be mapped to unit exception.  Same goes for
unexpected error codes and absence of required ORB flags.

e443ef9f21 s390x/css: IO instr handler ending control
CSS code needs to tell the IO instruction handlers located in ioinst.c
how the emulated instruction should be ended. Currently this is done by
returning generic (POSIX) error codes, and mapping them to outcomes like
condition codes. This makes bugs easy to create and hard to recognize.

As a preparation for moving away from (mis)using generic error codes for
flow control let us introduce a type which tells the instruction
handler function how to end the instruction, in a more straight-forward
and less ambiguous way.

67915de9f0 s390x/event-facility: variable-length event masks
The architecture supports masks of variable length for sclp write
event mask. We currently only support 4 byte event masks, as that
is what Linux uses.

Let's extend this to the maximum mask length supported by the
architecture and return 0 to the guest for the mask bits we don't
support in core.

04162f8f4b qdev: store DeviceState's canonical path to use when unparenting
device_unparent(dev, ...) is called when a device is unparented,
either directly, or as a result of a parent device being
finalized, and handles some final cleanup for the device. Part
of this includes emiting a DEVICE_DELETED QMP event to notify
management, which includes the device's path in the composition
tree as provided by object_get_canonical_path().

object_get_canonical_path() assumes the device is still connected
to the machine/root container, and will assert otherwise, but
in some situations this isn't the case:

If the parent is finalized as a result of object_unparent(), it
will still be attached to the composition tree at the time any
children are unparented as a result of that same call to
object_unparent(). However, in some cases, object_unparent()
will complete without finalizing the parent device, due to
lingering references that won't be released till some time later.
One such example is if the parent has MemoryRegion children (which
take a ref on their parent), who in turn have AddressSpace's (which
take a ref on their regions), since those AddressSpaces get cleaned
up asynchronously by the RCU thread.

In this case qdev:device_unparent() may be called for a child Device
that no longer has a path to the root/machine container, causing
object_get_canonical_path() to assert.

Fix this by storing the canonical path during realize() so the
information will still be available for device_unparent() in such
cases.

4a12c699d3 ppc: pnv: use generic cpu_model parsing
use common cpu_model prasing in vl.c and set default cpu_model
using generic MachineClass::default_cpu_type.

Beside of switching to generic infrastructure it solves several
issues.

 * ppc_cpu_class_by_name() is used to deal with lower/upper case
   and alias translations into actual cpu type, which fixes
    '-M powernv -cpu power8' and '-M powernv -cpu power9_v1.0'
   usecases which error out with:
    'invalid CPU model 'FOO' for powernv machine'
 * allows to switch to lower-case typenames in pnv chip/core name
   (by convention typnames should be lower-case)
 * replace aliased names /power8, power9, .../ with exact cpu model
   names (i.e. typenames should be stable but aliases might decide to
   point to other cpu model withi family or changed by kvm). It will
   also help to simplify pnv_chip/core code and get rid of dependency
   on cpu_model parsing.

  * drop cpu_parse_cpu_model() from hw/ppc/spapr.c and reuse

there is a dedicated callback CPUClass::parse_features
which purpose is to convert -cpu features into a set of

that couldn't be directly translated into CPU's properties.

Create ppc variant of it (ppc_cpu_parse_featurestr) and
move 'compat=val' handling from spapr_cpu_core.c into it.
That removes a dependency of board/core code on cpu_model
parsing and would let to reuse common -cpu parsing
introduced by 6063d4c0

Set "max-cpu-compat" property only if it exists, in practice
it should limit 'compat' hack to spapr machine and allow

        type_register_static(&type_infos[i]);

 }

 type_init(foo_register_types)

with a single line

 DEFINE_TYPES(type_infos)

where types have static definition which could be consolidated in
a single array of TypeInfo structures.
It saves us ~6-10LOC per use case and would help to replace
imperative foo_register_types() there with declarative style of

8dfd5f9651 io: get rid of bounce buffering in websock write path
Currently most outbound I/O on the websock channel gets copied into the
rawoutput buffer, and then immediately copied again into the encoutput
buffer, with a header prepended. Now that qio_channel_websock_encode
accepts a struct iovec, we can trivially remove this bounce buffering
and write directly to encoutput.

In doing so, we also now correctly validate the encoutput size against
the QIO_CHANNEL_WEBSOCK_MAX_BUFFER limit.

57b0cdf152 io: simplify websocket ping reply handling
We must ensure we don't get flooded with ping replies if the outbound
channel is slow. Currently we do this by keeping the ping reply in a
separate temporary buffer and only writing it if the encoutput buffer
is completely empty. This is overly pessimistic, as it is reasonable
to add a ping reply to the encoutput buffer even if it has previous
data in it, as long as that previous data doesn't include a ping
reply.

To track this better, put the ping reply directly into the encoutput
buffer, and then record the size of encoutput at this time in
pong_remain. As we write encoutput to the underlying channel, we
can decrement the pong_remain counter. Once it hits zero, we can
accept further ping replies for transmission.

bcd5ac9bcb ui: convert common input code to keycodemapdb
Replace the number_to_qcode, qcode_to_number and linux_to_qcode
tables with automatically generated tables.

Missing entries in linux_to_qcode now fixed:

  KEY_LINEFEED -> Q_KEY_CODE_LF
  KEY_KPEQUAL -> Q_KEY_CODE_KP_EQUALS
  KEY_COMPOSE -> Q_KEY_CODE_COMPOSE
  KEY_AGAIN -> Q_KEY_CODE_AGAIN
  KEY_PROPS -> Q_KEY_CODE_PROPS
  KEY_UNDO -> Q_KEY_CODE_UNDO
  KEY_FRONT -> Q_KEY_CODE_FRONT
  KEY_COPY -> Q_KEY_CODE_COPY
  KEY_OPEN -> Q_KEY_CODE_OPEN
  KEY_PASTE -> Q_KEY_CODE_PASTE
  KEY_CUT -> Q_KEY_CODE_CUT
  KEY_HELP -> Q_KEY_CODE_HELP
  KEY_MEDIA -> Q_KEY_CODE_MEDIASELECT

In addition, some fixes:

 - KEY_PLAYPAUSE now maps to Q_KEY_CODE_AUDIOPLAY, instead of
   KEY_PLAYCD. KEY_PLAYPAUSE is defined across almost all scancodes
   sets, while KEY_PLAYCD only appears in AT set1, so the former is
   a more useful mapping.

Missing entries in qcode_to_number now fixed:

  Q_KEY_CODE_AGAIN -> 0x85
  Q_KEY_CODE_PROPS -> 0x86
  Q_KEY_CODE_UNDO -> 0x87
  Q_KEY_CODE_FRONT -> 0x8c
  Q_KEY_CODE_COPY -> 0xf8
  Q_KEY_CODE_OPEN -> 0x64
  Q_KEY_CODE_PASTE -> 0x65
  Q_KEY_CODE_CUT -> 0xbc
  Q_KEY_CODE_LF -> 0x5b
  Q_KEY_CODE_HELP -> 0xf5
  Q_KEY_CODE_COMPOSE -> 0xdd
  Q_KEY_CODE_KP_EQUALS -> 0x59
  Q_KEY_CODE_MEDIASELECT -> 0xed

In addition, some fixes:

 - Q_KEY_CODE_MENU was incorrectly mapped to the compose
   scancode (0xdd) and is now mapped to 0x9e
 - Q_KEY_CODE_FIND was mapped to 0xe065 (Search) instead
   of to 0xe041 (Find)
 - Q_KEY_CODE_HIRAGANA was mapped to 0x70 (Katakanahiragana)
   instead of of 0x77 (Hirigana)
 - Q_KEY_CODE_PRINT was mapped to 0xb7 which is not a defined
   scan code in AT set 1, it is now mapped to 0x54 (sysrq)

5f9252f7cc fw_cfg: add write callback
Reintroduce the write callback that was removed when write support was
removed in commit 023e314856.

Contrary to the previous callback implementation, the write_cb
callback is called whenever a write happened, so handlers must be
ready to handle partial write as necessary.
