2015-06-02target-arm: Add GIC phandle to VirtBoardInfoChristoffer Dall1-15/+11
Instead of passing the GIC phandle around between functions, add it to the VirtBoardInfo just like we do for the clock_phandle. We are about to add the v2m phandle as well, and it's easier not having to pass around a bunch of phandles, return multiple values from functions, etc. Reviewed-by: Eric Auger <eric.auger@linaro.org> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Christoffer Dall <christoffer.dall@linaro.org> Message-id: 1432897270-7780-2-git-send-email-christoffer.dall@linaro.org Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

On migration a full 64bit guest_features field is sent if one of the high bits is set, in addition to the lower 32bit guest_features field which must stay for compatibility reasons. That way we send the lower 32 feature bits twice, but the code is simpler because we don't have to split and compose the 64bit features into two 32bit fields.

Following the recent upgrade to version 1.3, extend the TPM TIS interface with capabilities introduced for support of a TPM 2. TPM TIS for TPM 2 introduced the following extensions beyond the TPM TIS 1.3 (used for TPM 1.2): - A new 32bit interface Id register was introduced. - New flags for the status (STS) register were defined. - New flags for the capability flags were defined. Support the above if a TPM TIS 1.3 for TPM 2 is used with a TPM 2 on the backend side. Support the old TPM TIS 1.3 configuration if a TPM 1.2 is being used. A subsequent patch will then determine which TPM version is being used in the backend. Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Reviewed-by: Michael S.

2015-05-31i386/pc_q35: don't insist on board FDC if there's no default floppyLaszlo Ersek1-2/+2
The "no_floppy = 1" machine class setting causes "default_floppy" in main() to become zero. Consequently, default_drive() will not call drive_add() and drive_new() for IF_FLOPPY, index=0, meaning that no default floppy drive will be created for the virtual machine. In that case, board code should also not insist on the creation of the board-default FDC. The board-default FDC will still be created if the user requests a floppy drive with "-drive if=floppy". Additionally, separate FDCs can be specified manually with "-device isa-fdc". They allow the -device isa-fdc,driveA=... syntax that is more flexible than the one required by the board-default FDC: -global isa-fdc.driveA=... This patch doesn't change the behavior observably, as all Q35 machine types have "no_floppy = 0".

2015-05-31i386/pc: pc_basic_device_init(): delegate FDC creation requestLaszlo Ersek4-3/+5
This patch introduces no observable change, but it allows the callers of pc_basic_device_init(), ie. pc_init1() and pc_q35_init(), to request (or not request) the creation of the FDC explicitly. At the moment both callers pass constant create_fdctrl=true (hence no observable change). Assuming a board passes create_fdctrl=false, "floppy" will be NULL on output, and (beyond the FDC not being created) that NULL will be passed on to pc_cmos_init(). Luckily, pc_cmos_init() already handles that case.

2015-05-31virtio: device_plugged() can failJason Wang5-8/+12
This patch passes error pointer to transport specific device_plugged() callback. Through this way, device_plugged() can do some transport specific check and fail. This will be uesd by following patches that check the number of virtqueues against the transport limitation.

2015-05-31virtio: move VIRTIO_F_NOTIFY_ON_EMPTY into coreCornelia Huck4-18/+6
Nearly all transports have been offering VIRTIO_F_NOTIFY_ON_EMPTY, s390-virtio being the exception. There's no reason why it shouldn't offer it as well, though (handling is done in core anyway), so let's move it to the common virtio features. While we're changing it anyway, fix the indentation for the DEFINE_VIRTIO_COMMON_FEATURES macro. Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com> Reviewed-by: Michael S.
