This was indeed implemented through support for the DATA_SET_MANAGEMENT
command, in hw/ide/core.c. If you are having specific issues here in
2016, please file a more specific bug.

Title:
[Feature request] Please implement ATA TRIM command
Status in QEMU:
New
Bug description:
Modern linuxes can use ATA TRIM command on block devices. It will be
very nice if qemu translates this request to underlying block driver.
1. So, if I use RAW image (on my case - lvm partition), TRIM inside qemu
should do TRIM command on my readl HDD
2. In the future, TRIM command inside qemu will free space inside qcow images.
