[PATCH for-9.0 0/4] target/riscv: add RVV CSRs

Posted by Daniel Henrique Barboza 12 months ago

Hi,

This series adds RVV, vstart, vl and vtype regs to the KVM driver.

But first we need a couple of things done. We need 'ptrace.h' RISC-V
linux-header to be able to read/write RVV CSRs. This is done in patch 2.
Patch 1 is the usual linux-header bump for all archs.

Patch 3 is adding a realize() callback for the KVM driver because we're
doing a prctl() to enable Vector support for the thread.

Patches are based on master. You'll need the following KVM fix to be
able to build:

[PATCH for-8.2] target/riscv/kvm: fix shadowing in kvm_riscv_(get|put)_regs_csr


Daniel Henrique Barboza (4):
  linux-headers: Update to Linux v6.7-rc3
  linux-headers: riscv: add ptrace.h
  target/riscv/kvm: do PR_RISCV_V_SET_CONTROL during realize()
  target/riscv/kvm: add RVV and Vector CSR regs
