[Qemu-devel] [PATCH v3 00/19] qtest/ahci: add dma test

[John Snow <jsnow@redhat.com>]

Add a simple DMA r/w test to ahci-test.

Oh, and for the first 18 patches, refactor everything into helpers so
that each ahci_test isn't a thousand lines long.

This patch depends upon the "ahci test preliminary refactoring" series
upstream, which shuffled a lot of libqos and malloc facilities to
support this series.

This patchset is a necessary step in checking in AHCI/DMA migration
tests that I will later use as proof as suitability of enabling the
ICH9 and AHCI migration flags.

V3:
 (04) Changed "px" to "port" and "cx" to "slot" In this and all other patches.
      Kept R-Bys in other patches as this is a non-functional change.
 (10) Modified aux to be an array of four bytes, and added a note
      explaining that they are for NCQ and not currently used in libqos.
 (12) Minor formatting and updating aux initialization. Kept R-B.

V2:
 (03) Added cpu_to_le16 into intermediary code.
 (04) Fixed assignment to be or-equals.
      ahci_set_command_header no longer modifies its argument.
 (09) Fixed assignment to be or-equals in the helper refactor.
 (10) New patch. Writes an FIS to guest memory, handling endianness.
 (11) Remove the property table sentinel
      update find_command to use the array size instead.
 (12) Remove cpu_to_le16 from ahci_command_commit,
      leave endianness to ahci_write_fis.
 (14) Remove cpu_to_le16 from ahci_set_sizes,
      leave endianness to ahci_write_fis.
 (19) qmemset the buffer to zeroes between IO calls,
      just to make sure.
 (--) Removed the ahci_macro_boot function patch
      (...for now...)
 (--) Retested entire stack of patches on F20/PPC.
