From 7d6c40da198ac18bd5dd2cd18628d5b4c615d842 Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Sat, 28 Mar 2015 14:21:09 +1100 Subject: [PATCH] KVM: PPC: Book3S HV: Use bitmap of active threads rather than count Currently, the entry_exit_count field in the kvmppc_vcore struct contains two 8-bit counts, one of the threads that have started entering the guest, and one of the threads that have started exiting the guest. This changes it to an entry_exit_map field which contains two bitmaps of 8 bits each. The advantage of doing this is that it gives us a bitmap of which threads need to be signalled when exiting the guest. That means that we no longer need to use the trick of setting the HDEC to 0 to pull the other threads out of the guest, which led in some cases to a spurious HDEC interrupt on the next guest entry.
