The patch has added an 'enter_hyp' call into the chunk of code which is relocated to some random address, which means the code is now too long and we only relocate half of it. So when the primary CPU wakes up the secondaries they just run off into the weeds. Solution: move the enter_hyp to before the secondary-CPU pen code rather than after it. Unless anybody objects I propose to commit these three bootwrapper patches (with the above one-line fix) tomorrow. -- PMM _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/cucslists/listinfo/kvmarm
