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

From: John Snow
Subject: [Qemu-devel] [PATCH v3 00/19] qtest/ahci: add dma test
Date: Thu, 5 Feb 2015 12:41:11 -0500

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.

 (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.

 (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.
