On ARM hosts with CTR_EL0.DIC and CTR_EL0.IDC set, this would only cause
an ISB to be executed during cache maintenance, which could lead to QEMU
executing TBs containing garbage instructions.
This seems to be because the ISB finishes executing instructions and
flushes the pipeline, but the ISB do
Support asynchronous fencing feature of virglrenderer. It allows Qemu to
handle fence as soon as it's signalled instead of periodically polling
the fence status. This feature is required for enabling DRM context
support in Qemu because legacy fencing mode isn't supported for DRM
contexts in virglre
Register an event notifier handler to process AP configuration
change events by queuing the event and generating a CRW to let
the guest know its AP configuration has changed

Updated Aspeed27x0SoCState to include an intc[2] array instead of a single
AspeedINTCState instance. Modified aspeed_soc_ast2700_get_irq and
aspeed_soc_ast2700_get_irq_index to correctly reference the corresponding
interrupt controller instance and OR gate index.
Currently, only GIC 192 to 201 are

Hello,
So far I've figured out that I need to add a member called SplitIRQ
in the BCMSocPeripheralBaseState struct, which is of size defined
by `BCM2835_NUM_SPLITTERS`. Then from what I can tell through
reading through the codebase, I should do something similar to
what happens in `exynos4210.c`

Migrate the tick_offset directly, adding it as a version-dependent field

Is this a qemu-stable material?
It is proba

At this point, we finished to extract memory API from cpu-all.h, and it
can be called from any common or target dependent code.
