Subject: [PATCH 0/5] memory: Forbid mapping AddressSpace root MemoryRegion
Date: Fri, 12 Mar 2021 19:28:46 +0100 [thread overview]
Message-ID: <20210312182851.1922972-1-f4bug@amsat.org> (raw)
Hi,
This series is the result of a long thread with Peter:
https://www.mail-archive.com/qemu-devel@nongnu.org/msg788366.html
AddressSpace are physical address view and shouldn't be using
non-zero base address. The correct way to map a MR used as AS
root is to use a MR alias.
Fix the current incorrect uses, then forbid further use.
Peter Xu (1):
memory: Make sure root MR won't be added as subregion
Philippe Mathieu-Daudé (4):
hw/arm/aspeed: Do not directly map ram container onto main address bus
hw/arm/aspeed: Do not sysbus-map mmio flash region directly, use alias
hw/pci-host/prep: Remove unuseful memory region mapping
hw/pci-host/prep: Do not directly map bus-master region onto main bus
