25 | sata_mv TODO list: | ||
26 | |||
27 | 1) Needs a full errata audit for all chipsets. I implemented most | ||
28 | of the errata workarounds found in the Marvell vendor driver, but | ||
29 | I distinctly remember a couple workarounds (one related to PCI-X) | ||
30 | are still needed. | ||
31 | |||
32 | 2) Convert to LibATA new EH. Required for hotplug, NCQ, and sane | ||
33 | probing/error handling in general. MUST HAVE. | ||
34 | |||
35 | 3) Add hotplug support (easy, once new-EH support appears) | ||
36 | |||
37 | 4) Add NCQ support (easy to intermediate, once new-EH support appears) | ||
38 | |||
39 | 5) Investigate problems with PCI Message Signalled Interrupts (MSI). | ||
40 | |||
41 | 6) Add port multiplier support (intermediate) | ||
42 | |||
43 | 7) Test and verify 3.0 Gbps support | ||
44 | |||
45 | 8) Develop a low-power-consumption strategy, and implement it. | ||
46 | |||
47 | 9) [Experiment, low priority] See if ATAPI can be supported using | ||
48 | "unknown FIS" or "vendor-specific FIS" support, or something creative | ||
49 | like that. | ||
50 | |||
51 | 10) [Experiment, low priority] Investigate interrupt coalescing. | ||
52 | Quite often, especially with PCI Message Signalled Interrupts (MSI), | ||
53 | the overhead reduced by interrupt mitigation is quite often not | ||
54 | worth the latency cost. | ||
55 | |||
56 | 11) [Experiment, Marvell value added] Is it possible to use target | ||
57 | mode to cross-connect two Linux boxes with Marvell cards? If so, | ||
58 | creating LibATA target mode support would be very interesting. | ||
59 | |||
60 | Target mode, for those without docs, is the ability to directly | ||
61 | connect two SATA controllers. | ||
62 | |||
63 | 13) Verify that 7042 is fully supported. I only have a 6042. | ||
