+cpu feature selection is not affected to guest 's cpuid with whpx
+
+On windows with -accel whpx, "-cpu" is ignored without any messages.
+Guest recognizes features as same as host's.
+
+Confirmed on v5.2.0-rc1.
+
+I suggest qemu may do,
+
+- Warn with incompatible -cpu options were given.
+- Enhance cpuid handling.
+
+Background:
+I was investigated mmio and block copy issue in Linux kernel.
+I met a problem that Linux went ill for touching mmio with whpx. (not with tcg)
+I suspect erms(enhanced rep movs) might trigger.
+I tried to mask erms on qemu with -feature,erms, but it was ineffective.
+
+At last, I disabled erms manually, to tweak whpx-all.c to mask erms in cpuid.
+
+FYI, qemu with whpx from/to mmio, "rep movsb" does byte access regardless of erms.
+Linux kernel tends to choose not "rep movsq" but "rep movsb" with erms.

+The QEMU project is currently moving its bug tracking to another system.
+For this we need to know which bugs are still valid and which could be
+closed already. Thus we are setting the bug state to "Incomplete" now.
+
+If the bug has already been fixed in the latest upstream version of QEMU,
+then please close this ticket as "Fix released".
+
+If it is not fixed yet and you think that this bug report here is still
+valid, then you have two options:
+
+1) If you already have an account on gitlab.com, please open a new ticket
+for this problem in our new tracker here:
+
+    https://gitlab.com/qemu-project/qemu/-/issues
+
+and then close this ticket here on Launchpad (or let it expire auto-
+matically after 60 days). Please mention the URL of this bug ticket on
+Launchpad in the new ticket on GitLab.
+
+2) If you don't have an account on gitlab.com and don't intend to get
+one, but still would like to keep this ticket opened, then please switch
+the state back to "New" or "Confirmed" within the next 60 days (other-
+wise it will get closed as "Expired"). We will then eventually migrate
+the ticket automatically to the new system (but you won't be the reporter
+of the bug in the new system and thus you won't get notified on changes
+anymore).
+
+Thank you and sorry for the inconvenience.
+
+
+[Expired for QEMU because there has been no activity for 60 days.]
