memory: avoid updating ioeventfds for some address_space (2023-09-19 10:44:44 +0200)
----------------------------------------------------------------
Hi,
"Host Memory Backends" and "Memory devices" queue ("mem"):
- Support and document VM templating with R/O files using a new "rom"
parameter for memory-backend-file
- Some cleanups and fixes around NVDIMMs and R/O file handling for guest
RAM
- Optimize ioeventfd updates by skipping address spaces that are not
applicable
----------------------------------------------------------------
David Hildenbrand (11):
nvdimm: Reject writing label data to ROM instead of crashing QEMU
softmmu/physmem: Distinguish between file access mode and mmap
protection
backends/hostmem-file: Add "rom" property to support VM templating
with R/O files
softmmu/physmem: Remap with proper protection in qemu_ram_remap()
softmmu/physmem: Bail out early in ram_block_discard_range() with
readonly files
softmmu/physmem: Fail creation of new files in file_ram_open() with
readonly=true
softmmu/physmem: Never return directories from file_ram_open()
docs: Don't mention "-mem-path" in multi-process.rst
docs: Start documenting VM templating
softmmu/physmem: Hint that "readonly=on,rom=off" exists when opening
file R/W for private mapping fails
machine: Improve error message when using default RAM backend id
