[PATCH v2 0/6] target/arm: Fixes for RME

Posted by Jean-Philippe Brucker 9 months, 1 week ago

A few patches to fix RME support and allow booting a realm guest, based
on https://lore.kernel.org/qemu-devel/20230714154648.327466-1-peter.maydell@linaro.org/

Since v1 I fixed patches 1, 2 and 6 following Peter's comments, and
added patch 5. Patch 6 now factors the timer IRQ update into a new
function, which is a bit invasive but seems cleaner.

v1: https://lore.kernel.org/qemu-devel/20230719153018.1456180-2-jean-philippe@linaro.org/

  target/arm/ptw: Load stage-2 tables from realm physical space
