[Qemu-devel] [PATCH v7 0/8] memory API improvements and bug fixes for memory backends

[Hu Tao]

This series includes two parts:
 
  1. part 1 includes patches 1-4, which improves error handling of
     memory_region_init_ram, memory_region_init_ram_ptr and
     memory_region_init_rom_device
 
  2. part 2 includes patches 5-8, each fixes a bug of memory backend.
 
changes:

  v7:
  - split the memory-file preallocation fix into its own patch(patch 6)
  - some commit messages tweaks

  v6:
  - split patch 6 in v5 into 2
  - use local_err instead of errp
  - typo fixes

  v5:
  - don't introduce _may_fail and _nofail versions of memory API
  - the patches order of bug fix and memory API change is exchanged, first
    comes the API change, then bug fix.

  v4:
  - fix build on 32bit host
  - add memory API renaming
  - rebase on latest master

  v3:
  - introduce memory_region_init_ram_may_fail and
    memory_region_init_ram_ptr_may_fail
  - address comments by MST
  - missing the functions renaming. will send later.

  v2:
  - split patch 1 in v1 into 2 patches
  - don't rely on ram_block_add to return -1
  - error message tweak in file_ram_alloc
  - add error messages reported by qemu to commit message of patch 3

  v1:
  - initial version

Hu Tao (8):
  exec: add parameter errp to qemu_ram_alloc and qemu_ram_alloc_from_ptr
  memory: add parameter errp to memory_region_init_ram
  memory: add parameter errp to memory_region_init_ram_ptr
  memory: add parameter errp to memory_region_init_rom_device
  hostmem-ram: don't exit qemu if size of memory-backend-ram is way too
    big
  exec: file_ram_alloc: don't exit if failed to preallocate memory
  exec: report error when memory < hpagesize
  exec: add parameter errp to gethugepagesize
