Subject: [PATCH 00/15] arm64: KVM: add SPE profiling support for guest
Date: Thu, 23 May 2019 11:34:47 +0100 [thread overview]
Message-ID: <20190523103502.25925-1-sudeep.holla@arm.com> (raw)
Hi,
This series implements support for allowing KVM guests to use the Arm
Statistical Profiling Extension (SPE).
The patches are also available on a branch[1]. The last two extra
patches are for the kvmtool if someone wants to play with it.
Regards,
Sudeep
v1->v2:
- Rebased on v5.2-rc1
- Adjusted sysreg_elx_s macros with merged clang build support

Sudeep Holla (15):
KVM: arm64: add {read,write}_sysreg_elx_s versions for new registers
dt-bindings: ARM SPE: highlight the need for PPI partitions on
heterogeneous systems
arm64: KVM: reset E2PB correctly in MDCR_EL2 when exiting the
guest(VHE)
arm64: KVM: define SPE data structure for each vcpu
arm64: KVM: add access handler for SPE system registers
arm64: KVM/VHE: enable the use PMSCR_EL12 on VHE systems
arm64: KVM: split debug save restore across vm/traps activation
arm64: KVM/debug: drop pmscr_el1 and use sys_regs[PMSCR_EL1] in
kvm_cpu_context
arm64: KVM: add support to save/restore SPE profiling buffer controls
arm64: KVM: enable conditional save/restore full SPE profiling buffer
controls
arm64: KVM/debug: trap all accesses to SPE controls at EL1
KVM: arm64: add a new vcpu device control group for SPEv1
KVM: arm64: enable SPE support
KVMTOOL: update_headers: Sync kvm UAPI headers with linux v5.2-rc1
KVMTOOL: kvm: add a vcpu feature for SPEv1 support
