Subject: [PATCH kvm-unit-tests v3 0/8] arm/arm64: Prepare for target-efi
Date: Thu, 29 Apr 2021 18:41:22 +0200 [thread overview]
Message-ID: <20210429164130.405198-1-drjones@redhat.com> (raw)
v3:
- Picked up Alex's r-b on patch 1 and 5
- Removed useless cast in pci_host_bridge_get_paddr [Andre]
- Added XN bits when mapping I/O pages [Alex]
- Tweaks to patch 6 suggested by Alex and myself
- Improved patch 8 commit message and changed psci-invoke's input
and output parameter types
v2:
- Addressed all comments from Nikos and Alex
- The biggest changes are
* dropping the weird persistent map stuff that I never liked by taking
Alex's suggestion to just create the idmap early
* adding mem_region_add() to clean up memory region adding code, also
improved the assignment of region fields
- Also, while we found that we still have a memory map assumption
(3G-4G reserved for virtual memory allocation), I only make that
assumption clear. I've left removing it for an additional patch
for another day.
- Added psci_invoke_none() to use prior to the PSCI method being set
- Added r-b's for each patch given, unless the commit changed too much
- Didn't take Alex's suggestion to use x5 for stacktop when calling
setup from start. I prefer explicitly loading it again.
This series is a collection of patches derived from [1] that pave the
way for new targets, e.g. target-efi[2]. These patches mostly address
the elimination of memory map assumptions and they shouldn't have any
functional changes. The last two patches are a couple of patches not
related to the memory map, but they also prepare for bare metal targets.
I tossed them in since I don't think they should be too controversial.
This patch series is also available here [3].
