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

[1] git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux.git kvm_spe

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
