12/31/2022 0 Comments Silicon image 3132 driver![]() ![]() ![]() The PCI-X variant (3124) on 32 bit PCI 33MHz can reach the PCI bus limit.It generally works quite well but there are some known bandwidth limitations which show up with the higher bandwidth requirements from PMP. Sata_sil24 has FIS-switching Port Multiplier support. Summary: Full TCQ/NCQ support, with full SATA control including hotplug and PM. Looks like a PATA controller, but with full SATA control including hotplug and PM. Needs ATAPI support, so it may wind up using libata after all, for the non-disk devices. Not suited to libata architecture, a separate block driver "sx8" has been written for this hardware. Summary: Per-host queues, mostly full SATA control via firmware, including hotplug, PM, TCQ and NCQ support. Issue #7: With certain DIMMs (make sure they are top-quality ECC registered), there have been reports of data corruption. Users may wish to use the Promise driver to fully utilize the hardware. SX4 hardware is very "RAID friendly", particularly RAID1/5. Using the on-board DIMM as cache, and issuing each RAID transaction once (instead of once for each disk), will result in increased performance, but the driver doesn't do that yet. The SX4 hardware includes an on-board DIMM and hardware XOR offload. Issue #6: The SX4 hardware is not fully utilized by the Linux kernel driver. No SATA control (bridged PATA solution), so hotplug and SATA PM are not possible. Full SATA control including hotplug and PM on all. NOTE2: ATI, Intel, JMicron, NVIDIA, SiS, ULi and VIA are currently known to have deployed AHCI in their chipsets. NOTE1: AHCI specification is completely open. Summary: Full NCQ support, full SATA control including hotplug and PM. Update: Hotplug and NCQ are not yet supported by the driverģ100, CE 3100, ICH6 ~ ICH10, ESB2, NM10, PCH and Tolapai, "6 Series" (P67, H67, Q67 etc.) Looks like a standard AHCI controller, but with a few differences requiring a different driver. Summary: Full NCQ and full SATA control including hotplug and PM. Update: ICH5 includes support for MSI at its SATA controller in non combined mode. This is not yet supported in Linux, mainly because some BIOS do not fill in the necessary (PCI BAR) resources. Update: ICH6/7/8/9/10, PCH include support for addressing the SATA PHY registers. Looks like a PATA controller, but with a few added, non-standard SATA port controls. Information on the capabilites of the devices themselves is present in the list of hardware features. Link Power Management support for AHCI capable hardware is maturing, though a few devices have issues. 2.17 ADMA (including Pacific Digital Talon SATA).2.3 AHCI (newer Intel ICH, ULi, others). ![]()
