With the floating-point extension facility - CONVERT FROM LOGICAL - CONVERT TO LOGICAL - CONVERT TO FIXED - CONVERT FROM FIXED - LOAD FP INTEGER have both, a rounding mode specification and the inexact-exception control (XxC). Other instructions will be handled separatly. Check for valid rounding modes and forward also the XxC (via m4). To avoid a lot of boilerplate code and changes to the helpers, combine both, the m3 and m4 field in a combined 32 bit TCG variable. Perform checks at a central place, taking in account if the m3 or m4 field was ignore before the floating-point extension facility was introduced.

Some instructions allow to suppress IEEE inexact exceptions. z14 PoP, 9-23, "Suppression of Certain IEEE Exceptions" IEEE-inexact-exception control (XxC): Bit 1 of the M4 field is the XxC bit. If XxC is zero, recogni- tion of IEEE-inexact exception is not suppressed; if XxC is one, recognition of IEEE-inexact excep- tion is suppressed. Especially, handling for overflow/unerflow remains as is, inexact is reported along z14 PoP, 9-23, "Suppression of Certain IEEE Exceptions" For example, the IEEE-inexact-exception control (XxC) has no effect on the DXC; that is, the DXC for IEEE- overflow or IEEE-underflow exceptions along with the detail for exact, inexact and truncated, or inexact and incremented, is reported according to the actual con- dition. Follow up patches will wire it correctly up for the applicable instructions.

Let's split handling of BFP/DFP rounding mode configuration. Also, let's not reuse the sfpc handler, use a separate handler so we can properly check for specification exceptions for SRNMB.

We already forward the 3 bits correctly in the translation functions. We also have to handle them properly and check for specification exceptions. Setting an invalid rounding mode (BFP only, all DFP rounding modes) results in a specification exception. Setting unassigned bits in the fpc, results in a specification exception. This fixes LOAD FPC (AND SIGNAL), SET FPC (AND SIGNAL). Also for, SET BFP ROUNDING MODE, 3-bit rounding mode is now explicitly checked. Note: TCG_CALL_NO_WG is required for sfpc handler, as we now inject exceptions. We won't be modeling abscence of the "floating-point extension facility" for now, not necessary as most take the facility for granted without checking. z14 PoP, 9-23, "LOAD FPC" When the floating-point extension facility is installed, bits 29-31 of the second operand must specify a valid BFP rounding mode and bits 6-7, 14-15, 24, and 28 must be zero; otherwise, a specification exception is recognized.

IEEE underflows are not reported when the mask bit is off and we don't also have an inexact exception. z14 PoP, 9-20, "IEEE Underflow": An IEEE-underflow exception is recognized for an IEEE target when the tininess condition exists and either: (1) the IEEE-underflow mask bit in the FPC register is zero and the result value is inexact, or (2) the IEEE-underflow mask bit in the FPC register is one.

Many things are wrong and some parts cannot be fixed yet. Fix what we can fix easily and add two FIXMEs: The fpc flags are not updated in case an exception is actually injected. Inexact exceptions have to be handled separately, as they are the only exceptions that can coexist with underflows and overflows. I reread the horribly complicated chapters in the PoP at least 5 times and hope I got it right.

Let's detect normal and denormal ("subnormal") numbers reliably. Also test for quiet NaN's. As only one class is possible, test common cases first. While at it, use a better check to test for the mask bits in the data class mask. The data class mask has 12 bits, whereby bit 0 is the leftmost bit and bit 11 the rightmost bit. In the PoP an easy to read table with the numbers is provided for the VECTOR FP TEST DATA CLASS IMMEDIATE instruction, the table for TEST DATA CLASS is more confusing as it is based on 64 bit values. Factor the checks out into separate functions, as they will also be needed for floating point vector instructions. We can use a makro to generate the functions.

Use a new CC helper to calculate the CC lazily if needed. While the PoP mentions that "A 32-bit unsigned binary integer" is placed into the first operand, there is no word telling that the other 32 bits (high part) are left untouched. Maybe the other 32-bit are unpredictable. So store 64 bit for now. Bit magic courtesy of Richard.

Introduces hot plug/unplug support for the vfio-ap device. To hot plug a vfio-ap device using the QEMU device_add command: (qemu) device_add vfio-ap,sysfsdev=$path-to-mdev Where $path-to-mdev is the absolute path to the mediated matrix device to which AP resources to be used by the guest have been assigned. A vfio-ap device can be hot plugged only if: 1. A vfio-ap device has not been attached to the virtual machine's ap-bus via the QEMU command line or a prior hot plug action. 2. The guest was started with the CPU model feature for AP enabled (e.g., -cpu host,ap=on) To hot unplug a vfio-ap device using the QEMU device_del command: (qemu) device_del vfio-ap,sysfsdev=$path-to-mdev Where $path-to-mdev is the absolute path to the mediated matrix device specified when the vfio-ap device was attached to the virtual machine's ap-bus. A vfio-ap device can be hot unplugged only if: 1. A vfio-ap device has been attached to the virtual machine's ap-bus via the QEMU command line or a prior hot plug action. 2. The guest was started with the CPU model feature for AP enabled (e.g., -cpu host,ap=on) Please note that a hot plug handler is not necessary for the vfio-ap device because the AP matrix configuration for the guest is performed by the kernel device driver when the vfio-ap device is realized. The vfio-ap device represents a VFIO mediated device created in the host sysfs for use by a guest. The mdev device is configured with an AP matrix (i.e., adapters and domains) via its sysfs attribute interfaces prior to starting the guest or plugging a vfio-ap device in. When the device is realized, a file descriptor is opened on the mdev device which results in a callback to the vfio_ap kernel device driver. The device driver then configures the AP matrix in the guest's SIE state description from the AP matrix assigned via the mdev device's sysfs interfaces. The AP devices will be created for the guest when the AP bus running on the guest subsequently performs its periodic scan for AP devices. The qdev_simple_device_unplug_cb() callback function is used for the same reaons; namely, the vfio_ap kernel device driver will perform the AP resource de-configuration for the guest when the vfio-ap device is unplugged. When the vfio-ap device is unrealized, the mdev device file descriptor is closed which results in a callback to the vfio_ap kernel device driver. The device driver then clears the AP matrix configuration in the guest's SIE state description and resets all of the affected queues. The AP devices created for the guest will be removed when the AP bus running on the guest subsequently performs its periodic scan and finds there are no longer any AP resources assigned to the guest.

The locally allocated QDict-s need to be freed. ('file_layer' will be freed implicitly since it is added as an object to 'driver_layer'). Spotted by Coverity: CID 1398649 While in the neighbourhood free 'driver' and 'filename' as soon as they are added to the QDicts. Freeing after the 'done' label doesn't make that much sense as, if the error path jumps to that label, the values would be NULL anyway. This patch also makes that more obvious by taking the error path if 'params' is NULL and then asserting that both driver and filename are non-NULL in the normal path.

The function needs to make sure it is passed a valid disk name. This is easily done by making sure that the parsing loop results in a non-zero value.

The assignment to 'p' is unnecessary as the code will either goto 'invalid' or p will get overwritten.
