My previous patch set for replacing feature bits with id registers failed to consider that these id registers are beginning to control migration, and thus we must fill them in for KVM as well.
Thus, we want to initialize these values within CPU from the host. Finally, re-send the T32EE conversion patch, fixing the build failure on an arm32 host in kvm32.c. Changes, v2->v3: * Work around sysreg read failures from old host kernels. Changes, v1->v2: * Remove assert that AArch32 sysreg <= UINT32_MAX. * Remove unused local variable. * Add commentary for AArch32 sysregs vs missing AArch32 support. r~ Richard Henderson (5): target/arm: Install ARMISARegisters from kvm host target/arm: Fill in ARMISARegisters for kvm64 target/arm: Introduce read_sys_reg32 for kvm32 target/arm: Fill in ARMISARegisters for kvm32 target/arm: Convert t32ee from feature bit to isar3 test target/arm/cpu.h | 6 ++- target/arm/kvm_arm.h | 1 + linux-user/elfload.c | 2 +- target/arm/cpu.c | 4 -- target/arm/helper.c | 2 +- target/arm/kvm.c | 1 + target/arm/kvm32.c | 75 ++++++++++++++++++++---------------- target/arm/kvm64.c | 90 +++++++++++++++++++++++++++++++++++++++++++- target/arm/machine.c | 3 +- 9 files changed, 141 insertions(+), 43 deletions(-) -- 2.17.2
