[Qemu-devel] [PATCH v1 00/12] arm: Add first models of Xilinx Versal SoC

["Edgar E. Iglesias" <edgar.iglesias@gmail.com>]

From: "Edgar E. Iglesias" <edgar.iglesias@xilinx.com>

This patch series adds initial support for Xilinx's Versal SoC.
Xilinx is introducing Versal, an adaptive compute acceleration platform
(ACAP), built on 7nm FinFET process technology. Versal ACAPs combine Scalar
Processing Engines, Adaptable Hardware Engines, and Intelligent Engines with
leading-edge memory and interfacing technologies to deliver powerful
heterogeneous acceleration for any application. The Versal AI Core series has
five devices, offering 128 to 400 AI Engines. The series includes dual-core Arm
Cortex-A72 application processors, dual-core Arm Cortex-R5 real-time
processors, 256KB of on-chip memory with ECC, more than 1,900 DSP engines
optimized for high-precision floating point with low latency.

In QEMU we'd like to have a virtual developer board with the Versal SoC
and a selected set of peripherals under the control of QEMU.
We'd like to gradually extend this board as QEMU gains more support
for Versal hardware components. QEMU will generate a device-tree
describing only the components it supports and includes in the virtual
dev board.

Before adding Versal support, this series starts with a few fixes to the
GEM that I ran into when running recent kernels on the Versal and ZynqMP
models.

I also noticed a problem with HVC insns not being enabled when using
QEMU's PSCI implementation on CPU's with EL2 and EL3 enabled. This causes
problems for Linux/KVM guests, also fixed in this series.

Best regards,
Edgar
