··· 21 21 * 22 22 */ 23 23 24 + /* 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. 64 + 65 + */ 66 + 67 + 24 68 #include <linux/kernel.h> 25 69 #include <linux/module.h> 26 70 #include <linux/pci.h>
