No reply. Is this the right address to reach the megaraid_sas maintainers? Would you be interested in making sure the 2.6.32.y-based kernels used by various Linux distributors have up-to-date hardware support and fixes? What can I do to help make that happen? Thanks, Jonathan  http://bugs.debian.org/666108  Patches on top of 2.6.32.y used to add support for the 9240 family and similar devices: > c35188377f12 Add poll mechanism to megaraid sas driver > 72c4fd36dc7f add sysfs for AEN polling > 879111224d07 Add new megaraid SAS 2 controller support to the driver > 7bebf5c79cb6 allocate the application cmds to sas2 controller > 0c79e681eef1 Fix the fix for fw hang caused by megaraid sas application  Patches used to add Dell PERC H710P support: > 81e403ce3c6a infrastructure to get PDs from FW > 7e8a75f4dfbf Add the support for updating the OS after adding/removing > the devices from FW > bdc6fb8d69fa add the logical drive list to driver > c978684254d1 driver fixed the device update issue > f4c9a1317d32 add the IEEE SGE support to SAS2 controller > 39a985547cbf Add Online Controller Reset to MegaRAID SAS drive > 0d49016bbab4 Rename megaraid_sas.c to megaraid_sas_base.c > 80d9da98b403 Add MSI-X support and msix_disable module parameter > aeab3fd7b865 make driver PCI legacy I/O port free driver > b6d5d8808b4c Use lowest memory bar for SR-IOV VF support > cd50ba8ede5c Add struct megasas_instance_template changes > 9c915a8c99bc Add 9565/9285 specific code  Patches in 3.0.y absent from the above two lists: > 8d5682532133 tape drive support fix > 044833b572b9 report system PDs to OS > 7218df69e360 use the firmware boot timeout when waiting for commands > a0b7736828f7 Update version number and documentation > 780a3762fb92 Zero pad_0 in mfi structure > 63bad45db1d4 version and documentation update > 837f5fe89c84 support devices update flag > 1fd106851698 Add input parameter for max_sectors > 707e09bd867c Add three times Online controller reset > e340c3537239 Version and documentation update > 3f1530c1e1f7 Update GPL headers. > eb1b12377376 Fix failure gotos > 53ef2bbd2068 Add missing check_and_restore_queue_depth call > 0a77066acc78 Enable MSI-X before calling megasas_init_fw > e1419191d8d3 Call tasklet_schedule for MSI-X > 66192dfe1e74 Fix probe_one to clear MSI-X flags in kdump > f51244058963 Fix megasas_build_dcdb_fusion to not filter by TYPE_DISK > eaa3c240de25 Fix megasas_build_dcdb_fusion to use correct LUN field > 4c598b23807a Add CFG_CLEARED AEN > f86c5424b027 Fix tasklet_init call > 1ac515ef3f2f Fix fault state handling > 42a8d2b34d10 Fix max_sectors for IEEE SGL > ebf054b00b0a Fix iMR OCR support to work correctly > 00fa2b191b4b Version and Changelog update > 3f1abce4aba4 Remove MSI-X black list, use MFI_REG_STATE instead > 70d031f36fa5 Remove un-used function > 7e70e7336515 Check MFI_REG_STATE.fault.resetAdapter > 46fd256e0558 Disable interrupts/free_irq() in megasas_shutdown() > 541f90b7c6df Fix bug where AENs could be lost in probe() and resume() > 495c5609700e Convert 6,10,12 byte CDB's for FastPath IO > 3cc6851f9a35 Add 1078 OCR support > 4f788dce0baf Version and Changelog update -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
