Subject: [RFC PATCH v4 00/15] target/arm: Allow CONFIG_TCG=n builds
Date: Thu, 19 Jan 2023 10:54:09 -0300	[thread overview]
Message-ID: <20230119135424.5417-1-farosas@suse.de> (raw)

This series makes the necessary changes to allow the use of
--disable-tcg for arm.

Based on "target/arm: CONFIG_TCG=n part 1":
https://lore.kernel.org/r/20230118193518.26433-1-farosas@suse.de

Since v3:

Aside from minor review comments, the larger changes in this version
are:

- The split of 64-bit CPUs into tcg/cpu64.c. I have moved everything
  aside from the cortex-a53 and cortex-a57 cpus which could in theory
  be used with KVM.

- qtest vs. default cpu. By removing the default CPU for KVM we now
  need to make sure the tests pass a -cpu option.

  I don't think allowing tests without -cpu would be feasible because
  we'd have to go searching for every piece of code that assumes a cpu
  is always present.
