Subject: [GIT PULL] KVM/riscv changes for 6.10
Date: Sat, 4 May 2024 09:06:27 +0530 [thread overview]
Message-ID: <CAAhSdy3C7N11wV8U7qMWsKtT2U+_G_FsW8EVMER8fkKHPgy8rg@mail.gmail.com> (raw)
Hi Paolo,
We have the following KVM RISC-V changes for 6.10:
1) Support guest breakpoints using ebreak
2) Introduce per-VCPU mp_state_lock and reset_cntx_lock
3) Virtualize SBI PMU snapshot and counter overflow interrupts
4) New selftests for SBI PMU and Guest ebreak
Please pull.
Regards,
Anup
