2019-02-28hw/misc/armsse-mhu.c: Model the SSE-200 Message Handling UnitPeter Maydell3-0/+203
Implement a model of the Message Handling Unit (MHU) found in the Arm SSE-200. This is a simple device which just contains some registers which allow the two cores of the SSE-200 to raise interrupts on each other.

2019-02-25virtio-blk: Increase in_flight for request restart BHKevin Wolf1-0/+4
virtio_blk_dma_restart_bh() submits new requests, so in order to make sure that these requests are not started inside a drained section of the attached BlockBackend, we need to make sure that draining the BlockBackend waits for the BH to be executed. This BH is still questionable because its scheduled in the main thread instead of the configured iothread. Leave a FIXME comment for this. But with this fix, enabling the data plane at least waits for these requests (in bdrv_set_aio_context()) instead of changing the AioContext under their feet and making them run in the wrong thread, causing crashes and failures (e.g. due to missing locking).

2019-02-21vfio/common: Work around kernel overflow bug in DMA unmapAlex Williamson2-1/+20
A kernel bug was introduced in v4.15 via commit 71a7d3d78e3c which adds a test for address space wrap-around in the vfio DMA unmap path. Unfortunately due to overflow, the kernel detects an unmap of the last page in the 64-bit address space as a wrap-around. In QEMU, a Q35 guest with VT-d emulation and guest IOMMU enabled will attempt to make such an unmap request during VM system reset, triggering an error: qemu-kvm: VFIO_UNMAP_DMA: -22 qemu-kvm: vfio_dma_unmap(0x561f059948f0, 0xfef00000, 0xffffffff01100000) = -22 (Invalid argument) Here the IOVA start address (0xfef00000) and the size parameter (0xffffffff01100000) add to exactly 2^64, triggering the bug. A kernel fix is queued for the Linux v5.0 release to address this. This patch implements a workaround to retry the unmap, excluding the final page of the range when we detect an unmap failing which matches the requirements for this issue. This is expected to be a safe and complete workaround as the VT-d address space does not extend to the full 64-bit space and therefore the last page should never be mapped. This workaround can be removed once all kernels with this bug are sufficiently deprecated.

2019-02-21target/mips: fulong2e: Dynamically generate SPD EEPROM dataBALATON Zoltan1-18/+13
The machine comes with 256M memory module by default but it's upgradable so it could have different memory size. There was a TODO comment to replace static SPD EEPROM data with dynamically generated one to support this. Now that we have a function for that, it's easy to do. Although this would allow larger RAM sizes, the peculiar memory map of the machine may need some special handling to map it as low and high memory. Because I don't know what the correct place would be for highmem, I've left memory size fixed at 256M for now and TODO is moved there instead.

2019-02-21hw/arm/armsse: Make 0x5... alias region work for per-CPU devicesPeter Maydell1-10/+16
The region 0x40010000 .. 0x4001ffff and its secure-only alias at 0x50010000... are for per-CPU devices. We implement this by giving each CPU its own container memory region, where the per-CPU devices live. Unfortunately, the alias region which makes devices mapped at 0x4... addresses also appear at 0x5... is only implemented in the overall "all CPUs" container. The effect of this bug is that the CPU_IDENTITY register block appears only at 0x4001f000, but not at the 0x5001f000 alias where it should also appear. Guests (like very recent Arm Trusted Firmware-M) which try to access it at 0x5001f000 will crash. Fix this by moving the handling for this alias from the "all CPUs" container to the per-CPU container. (We leave the aliases for 0x1... and 0x3... in the overall container, because there are no per-CPU devices there.)

The Musca board puts its SRAM and flash behind TrustZone Memory Protection Controllers (MPCs). Each MPC sits between the CPU and the RAM/flash, and also has a set of memory mapped control registers. Wire up the MPCs, and the memory behind them. For the moment we implement the flash as simple ROM, which cannot be reprogrammed by the guest.

2019-02-21hw/misc/tz-ppc: Support having unused ports in the middle of the rangePeter Maydell1-0/+32
The Peripheral Protection Controller's handling of unused ports is that if there is nothing connected to the port's downstream then it does not create the sysbus MMIO region for the upstream end of the port. This results in odd behaviour when there is an unused port in the middle of the range: since sysbus MMIO regions are implicitly consecutively allocated, any used ports above the unused ones end up with sysbus MMIO region numbers that don't match the port number. Avoid this numbering mismatch by creating dummy MMIO regions for the unused ports. This doesn't change anything for our existing boards, which don't have any gaps in the middle of the port ranges they use; but it will be needed for the Musca board.
