This submission does not re-send patches 1-24, which are identical
to the v2 submission and have already been pulled onto
stefanha's block staging branch.
This patch series introduces a number of small fixes and tweaks to
help support an AHCI test suite that in the future I hope to expand
to a fuller regression suite to help guide the development of the
AHCI device support under, in particular, the Q35 machine type in QEMU.
Paolo Bonzini has contributed a number of cleanup and refactoring patches
that support changes to the PIO setup FIS packet construction code, which
is necessary for testing ths specification adherence of the IDENTIFY command,
which issues its data exclusively via PIO mechanisms.
The ahci-test code being checked in represents a minimum of functionality
needed in order to issue and receive commands from the AHCI HBA under the
libqos / qtest environment.
In V3, there is one assertion for incorrect behavior that is expected to
be fixed in a future patch set, where the Descriptor Processed interrupt
is not set or posted within the identify test.
V3:
- All tests complete successfully.
- Fixed the PCI capabilities ordering for AHCI.
- Corrected the boot-time values of the PxTFD and PxSIG registers
- Corrected PxTFD register being updated prior to PxCMD.FRE being set
V2:
"ide-test: add test for werror=stop"
- changed filename variable name
- altered the QMP event polling to avoid sleep
- debug_path file cleanup on exit.
"ide: stop PIO transfer on errors"
- Modified logic to be unconditional.
"ahci: construct PIO Setup FIS for PIO commands"
- Added in dma_memory_map success checks and error pathways.
"libqtest: Correct small memory leak."
- Corrected raw usage of free()
"ahci: Adding basic functionality qtest."
- Removed HBA type.
- Corrected cleanup order.
- Corrected raw usage of free()
- Removed needless conditional around g_free()
- Altered ahci_boot to return by value instead of parameter.
"ahci: Add test_pci_spec to ahci-test."
- Removed all ifdef logic in favor of runtime tuning. (--pedantic)
- Removed all warnings, all infractions are now hard assertions.
- Replaced g_assert with g_assert_cmphex in many cases
"ahci: add test_pci_enable to ahci-test."
- Removed MSI codepaths, as it was incomplete and unused.
"ahci: Add test_hba_spec to ahci-test."
- Removed unneeded macros
- Added in an optional bar_size return parameter to qpci_iomap
"ahci: Add test_identify case to ahci-test."
- Corrected raw usage of free()
