[Qemu-devel] [PATCH 0/2] ide/hw/core: fix bug# 1777315, crash on short P

Subject: [Qemu-devel] [PATCH 0/2] ide/hw/core: fix bug# 1777315, crash on short PRDs
Date: Wed, 20 Jun 2018 09:59:28 +0530

The fix utilizes the existing policy QEMU has about short PRDs, and
considers the transfers that cause the crash as generated through short
PRDS.

It
- continues to allow QEMU to support multiple calls to
  prepare_buf/ide_dma_cb,
- so, continues to keep QEMU free from needing the entire sglist in one
  go;
- avoids the crash;
- but, treats the affected transfers as short, instead of allowing them
  to continue.
