This series aims to do two main things:
(1) Eliminate global state out of the ahci-test file so that
the tests are more functional. This will allow me to write
migration tests more easily. These tests are already written
and will be submitted upstream after these refactor series.
(2) With global state removed from ahci-test, factor out functions
that would be useful to manipulate ahci devices into libqos/ahci.o,
to allow other testwriters to capitalize on the functional
refactoring.
So, as an overview, we do a few things:
- Clean up the malloc interface to have a clear pc-specific interface
that uses an architecture independent core.
- Add some new structures to help keep track of AHCI and libqos state.
- Rewrite existing AHCI helpers and routines to use the new structures
and helper routines.
- Excise any commonly valuable code to libqos/ahci.h and libqos/ahci.c.
This series therefore introduces no new functionality itself, but I was
trying to keep the series small and reviewable. The real necessity here
in jumbling malloc and ahci functions around is to create a functional
interface that can be bundled into a single structure to help facilitate
migration testing inside of qtests, for which I intend to export to all
of qtests to be re-used for other tests.
>From this point forward, the churn to my AHCI refactor series should be
significantly reduced and more pleasant to read.
Thanks,
John.
V2:
- #6 Made QGuestAllocator object opaque, in a new patch.
- Created page_size setter method.
- #7 Renamed "QOSOperations" to "QOSOps" and added Paolo's R-b.
- #12 Dropped GCC attributes from static inline helpers (ahci.h)
- #15 Adjusted assertion to not compare void ptr to int 0
- #15 Share ahci.o with libqos-obj-pc-y instead of only ahci-test
* ahci.o is pc-only for now.
