Subject: [PATCH v1 00/11] KVM: x86: break the xAPIC barrier
Date: Thu, 30 Jun 2016 22:54:18 +0200 [thread overview]
Message-ID: <20160630205429.16480-1-rkrcmar@redhat.com> (raw)
RFC: http://www.spinics.net/lists/kvm/msg132036.html
This series allows userspace to create and send interrupts to VCPUs with
APIC ID > 255.
v1: 32 bit API extensions now use a toggleable capability called
KVM_CAP_X2APIC_API.
* new [1/11], loosely related and should have been posted long ago
* [2/11] improved comment for kvm_apic_map_get_dest_lapic() [Peter]
* [3/11] use round_up [Peter]
* [6/11] drop big endian format in lapic get/set ioctl [Paolo]
* [6/11] exclude APICv optimization of APIC ID register
* [6/11] rename __kvm_apic_state_fixup() parameter
* new [7/11], split from the previous patch
* [8/11] added r-b [Peter]
* [10/11] rewritten with a toggleable capability [Paolo]
* [10/11] dropped MSI_ADDR_EXT_DEST_ID to enforce reserved bits
Latest Linux, FreeBSD, and Windows run fine, but I haven't tested VFIO.
Linux works even with APIC ID over 255. (QEMU and seabios patches to
achieve that are not yet posted.)
Radim Krčmář (11):
KVM: x86: bump KVM_SOFT_MAX_VCPUS to 240

KVM: x86: use generic function for MSI parsing
KVM: x86: use hardware-compatible format for APIC ID register
KVM: VMX: optimize APIC ID read with APICv
KVM: x86: directly call recalculate_apic_map on lapic restore
KVM: x86: reset lapic base in kvm_lapic_reset
KVM: x86: add KVM_CAP_X2APIC_API
KVM: x86: bump MAX_VCPUS to 288
