|
|
|
+ sata_mv TODO list:
|
|
|
+
|
|
|
+ 1) Needs a full errata audit for all chipsets. I implemented most
|
|
|
+ of the errata workarounds found in the Marvell vendor driver, but
|
|
|
+ I distinctly remember a couple workarounds (one related to PCI-X)
|
|
|
+ are still needed.
|
|
|
+
|
|
|
+ 2) Convert to LibATA new EH. Required for hotplug, NCQ, and sane
|
|
|
+ probing/error handling in general. MUST HAVE.
|
|
|
+
|
|
|
+ 3) Add hotplug support (easy, once new-EH support appears)
|
|
|
+
|
|
|
+ 4) Add NCQ support (easy to intermediate, once new-EH support appears)
|
|
|
+
|
|
|
+ 5) Investigate problems with PCI Message Signalled Interrupts (MSI).
|
|
|
+
|
|
|
+ 6) Add port multiplier support (intermediate)
|
|
|
+
|
|
|
+ 7) Test and verify 3.0 Gbps support
|
|
|
+
|
|
|
+ 8) Develop a low-power-consumption strategy, and implement it.
|
|
|
+
|
|
|
+ 9) [Experiment, low priority] See if ATAPI can be supported using
|
|
|
+ "unknown FIS" or "vendor-specific FIS" support, or something creative
|
|
|
+ like that.
|
|
|
+
|
|
|
+ 10) [Experiment, low priority] Investigate interrupt coalescing.
|
|
|
+ Quite often, especially with PCI Message Signalled Interrupts (MSI),
|
|
|
+ the overhead reduced by interrupt mitigation is quite often not
|
|
|
+ worth the latency cost.
|
|
|
+
|
|
|
+ 11) [Experiment, Marvell value added] Is it possible to use target
|
|
|
+ mode to cross-connect two Linux boxes with Marvell cards? If so,
|
|
|
+ creating LibATA target mode support would be very interesting.
|
|
|
+
|
|
|
+ Target mode, for those without docs, is the ability to directly
|
|
|
+ connect two SATA controllers.
|
|
|
+
|
|
|
+ 13) Verify that 7042 is fully supported. I only have a 6042.
