Christian, I'm pulling back this v4 and ask for v3 to be re-applied as it turned out that the described issue is related to kvm_s390_set_tod_clock() being called in SIE intercepted context. > > Changes in v3: > - cache and test GISA descriptor only once in kvm_s390_gisa_enable() > - modified some comments > - removed some whitespace issues > > Changes in v2: > - moved GISA disable into "put CPUs in PV mode" routine > - moved GISA enable into "pull CPUs out of PV mode" routine > > [1] https://lore.kernel.org/lkml/ae7c65d8-f632-a7f4-926a-50b9660673a1@linux.ibm.com/T/#mcb67699bf458ba7482f6b7529afe589d1dbb5930 > [2] https://lore.kernel.org/all/20220208165310.3905815-1-mimu@linux.ibm.com/ > [3] https://lore.kernel.org/all/20220209152217.1793281-2-mimu@linux.ibm.com/ > > Michael Mueller (2): > KVM: s390: pv: pull all vcpus out of SIE before converting to/from pv > vcpu > KVM: s390: pv: make use of ultravisor AIV support > > arch/s390/include/asm/uv.h | 1 + > arch/s390/kvm/interrupt.c | 54 +++++++++++++++++++++++++++++++++----- > arch/s390/kvm/kvm-s390.c | 19 +++++++++----- > arch/s390/kvm/kvm-s390.h | 11 ++++++++ > 4 files changed, 72 insertions(+), 13 deletions(-) >
This patch enables the ultravisor adapter interruption vitualization support. Changes in v4: - All vcpus are pulled out of SIE and disbled before the control blocks are changed to disable/enable the gisa and re-enabled afterwards instead of taking the vcpu specific lock. Changes in v3: - cache and test GISA descriptor only once in kvm_s390_gisa_enable() - modified some comments - removed some whitespace issues Changes in v2: - moved GISA disable into "put CPUs in PV mode" routine - moved GISA enable into "pull CPUs out of PV mode" routine [1] https://lore.kernel.org/lkml/ae7c65d8-f632-a7f4-926a-50b9660673a1@linux.ibm.com/T/#mcb67699bf458ba7482f6b7529afe589d1dbb5930 [2] https://lore.kernel.org/all/20220208165310.3905815-1-mimu@linux.ibm.com/ [3] https://lore.kernel.org/all/20220209152217.1793281-2-mimu@linux.ibm.com/ Michael Mueller (2): KVM: s390: pv: pull all vcpus out of SIE before converting to/from pv vcpu KVM: s390: pv: make use of ultravisor AIV support arch/s390/include/asm/uv.h | 1 + arch/s390/kvm/interrupt.c | 54 +++++++++++++++++++++++++++++++++----- arch/s390/kvm/kvm-s390.c | 19 +++++++++----- arch/s390/kvm/kvm-s390.h | 11 ++++++++ 4 files changed, 72 insertions(+), 13 deletions(-)
