Subject: Re: [Qemu-devel] [PATCH 00/16 RFC v6] ACPI memory hotplug
Date: Wed, 24 Jul 2013 17:52:50 +0800	[thread overview]
Message-ID: <20130724095249.GA26559@localhost.localdomain> (raw)

v6 doesn't work here, things are going fine until online hotplugged
memory in guest.

steps:

1. qemu cmd:

  ./x86_64-softmmu/qemu-system-x86_64 -enable-kvm -m 512,maxmem=2G,slots=1 \
  -hda /mnt/data/libvirt-images/hut-rhel6.3.img -L ../pc-bios-memhp/

  (bios is from MST's acpi tree)

2. hot-plug a dimm:

  device_adddimm,id=d0,size=1G

3. online hotplugged memory(in guest):

  echo 'onlone' > /sys/devices/system/memory/memory/32/state

then after several seconds the console prints error messages like:

  nommu_map_sg: overflow 107c15000+4096 of device mask ffffffff
  ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0
  ata1.00: cmd ca/00:10:d0:0d:a4/00:00:00:00:00/e0 tag 0 dma 8192 out
           res 50/00:00:08:09:e0/00:00:00:00:00/e0 Emask 0x40 (internal error)
  ata1.00: configured for MWDMA2
  ata1: EH complete

  (repeat)

and can't do any disk I/O.
