2019-11-11hw/arm/boot: Set NSACR.{CP11, CP10} in dummy SMC setup routinepull-target-arm-20191111Clement Deschamps
The boot.c code usually puts the CPU into NS mode directly when it is booting a kernel. Since fc1120a7f5f2d4b6 this has included a requirement to set NSACR to give NS state access to the FPU; we fixed that for the usual code path in ece628fcf6. However, it is also possible for a board model to request an alternative mode of booting, where its 'board_setup' code hook runs in Secure state and is responsible for doing the S->NS transition after it has done whatever work it must do in Secure state. In this situation the board_setup code now also needs to update NSACR. This affects all boards which set info->secure_board_setup, which is currently the 'raspi' and 'highbank' families. They both use the common arm_write_secure_board_setup_dummy_smc(). Set the NSACR CP11 and CP10 bits in the code written by that function, to allow FPU access in Non-Secure state when using dummy SMC setup routine. Otherwise an AArch32 kernel booted on the highbank or raspi boards will UNDEF as soon as it tries to use the FPU. Update the comment describing secure_board_setup to note the new requirements on users of it. This fixes a kernel panic when booting raspbian on raspi2.

2019-11-11Remove unassigned_access CPU hookPeter Maydell
All targets have now migrated away from the old unassigned_access hook to the new do_transaction_failed hook. This means we can remove the core-code infrastructure for that hook and the code that calls it.

2019-11-11ptimer: Remove old ptimer_init_with_bh() APIPeter Maydell
Now all the users of ptimers have converted to the transaction-based API, we can remove ptimer_init_with_bh() and all the code paths that are used only by bottom-half based ptimers, and tidy up the documentation comments to consider the transaction-based API the only possibility.

2019-11-06linux-user/sparc: Use WREG constants in sparc/target_cpu.hRichard Henderson
This fixes a naming bug wherein we used "UREG_FP" to access the stack pointer. OTOH, the "UREG_FP" constant was also defined incorrectly such that it *did* reference the stack pointer. Note that the kernel legitimately uses the name "FP", because it utilizes the rolled stack window in processing the system call.

2019-11-06virtio: notify virtqueue via host notifier when availableStefan Hajnoczi
Host notifiers are used in several cases: 1. Traditional ioeventfd where virtqueue notifications are handled in the main loop thread. 2. IOThreads (aio_handle_output) where virtqueue notifications are handled in an IOThread AioContext. 3. vhost where virtqueue notifications are handled by kernel vhost or a vhost-user device backend. Most virtqueue notifications from the guest use the ioeventfd mechanism, but there are corner cases where QEMU code calls virtio_queue_notify(). This currently honors the host notifier for the IOThreads aio_handle_output case, but not for the vhost case. The result is that vhost does not receive virtqueue notifications from QEMU when virtio_queue_notify() is called. This patch extends virtio_queue_notify() to set the host notifier whenever it is enabled instead of calling the vq->(aio_)handle_output() function directly. We track the host notifier state for each virtqueue separately since some devices may use it only for certain virtqueues. This fixes the vhost case although it does add a trip through the eventfd for the traditional ioeventfd case. I don't think it's worth adding a fast path for the traditional ioeventfd case because calling virtio_queue_notify() is rare when ioeventfd is enabled.

2019-11-06hw/rdma: Utilize ibv_reg_mr_iova for memory registrationYuval Shaia
The virtual address that is provided by the guest in post_send and post_recv operations is related to the guest address space. This address space is unknown to the HCA resides on host so extra step in these operations is needed to adjust the address to host virtual address. This step, which is done in data-path affects performances. An enhanced verion of MR registration introduced here https://patchwork.kernel.org/patch/11044467/ can be used so that the guest virtual address space for this MR is known to the HCA in host. This will save the data-path adjustment.
