Subject: [PATCH 00/65]target/riscv: Support XTheadVector extension
Date: Fri, 12 Apr 2024 15:36:30 +0800	[thread overview]
Message-ID: <20240412073735.76413-1-eric.huang@linux.alibaba.com> (raw)

This patchset implements the XTheadVector extension for RISC-V on QEMU.

You can find the full description of the XTheadVector extension at:
https://github.com/RISCV-SPEC/thead-extension-spec/blob/master/xtheadvector.adoc

The XTheadvector extension is a non-standard extension for RISC-V. The
encoding space of the XTheadVector instructions overlaps with those of
the V extension.

The XTheadVector is similar to the V extension v0.7.1, so it has several
differences with the current V extension v1.0 which is supported by
QEMU.

Here is a simple list of the differences:
  * Different instructions
  * Different CSR behaviors
  * Different mask register layout
  * Different overlap policy
  * Different masked/tail element processing policy
  * Same instructions have different behaviors in detail

This patchset is based on https://github.com/alistair23/qemu/tree/riscv-to-apply.next,
relay on some former patches which are not merged into upstream yet:
  * target/riscv: Implement dynamic establishment of custom decoder
  (https://patchew.org/QEMU/20240314092158.65866-1-eric.huang@linux.alibaba.com/)
  * riscv: set vstart_eq_zero on vector insns
  (https://patchew.org/QEMU/20240313220141.427730-1-dbarboza@ventanamicro.com/)
  * riscv: thead: Add th.sxstatus CSR emulation
  (https://patchew.org/QEMU/20240329120427.684677-1-christoph.muellner@vrull.eu/)


The patch 'riscv: thead: Add th.sxstatus CSR emulation' is included in the patchset
for we need to change it to support XTheadVector csrs.
