Yes, it must trap the IOCTL_STORAGE_MA
Hi paolo,
With -M pc,trim works well in windows guest with ide device and ahci bus.
About the filter driver,you mean do something in windows virtio-scsi
driver,let it send unmap command to qemu?

Hi paolo,
I test window guest with ide device with the following config,trim with ide
drive failed.
1 The host fs is ext4 with discard option:
/dev/sdb1 on /home/sdb type ext4 (rw,relatime,discard,data=ordered)
2 qemu config : ide drive with discard open
x86_64-softmm

Hi paolo,
Recently I test trim function,and it works well in linux guest with ext4 fs.
How to test it in windows guest? I got some info like this:
1 windows7 can send discard command when the storage device is ssd;
2 find a tool like 'fstrim', 'TRIM' the volume manually.
