| * [SCSI] megaraid_sas: FW transition and q size changesSumant Patro2006-10-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch has the following enhancements : a. handles new transition states of FW to support controller hotplug. b. It reduces by 1 the maximum cmds that the driver may send to FW. c. Sends "Stop Processing" cmd to FW before returning failure from reset routine d. Adds print in megasas_transition routine e. Sends "RESET" flag to FW to do a soft reset of controller to move from Operational to Ready state. f. Sending correct pointer (cmd->sense) to pci_pool_free Signed-off-by: Sumant Patro <Sumant.Patro@lsil.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

| * [SCSI] qla2xxx: Add iIDMA support.Andrew Vasquez2006-10-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | iIDMA (Intelligent Interleaved Direct Memory Access) allows for the HBA hardware to send FC frames at the rate at which they can be received by a target device. By taking advantage of the higher link rate, the HBA can maximize bandwidth utilization in a heterogeneous multi-speed SAN. Within a fabric topology, port speed detection is done via a Name Server command (GFPN_ID) followed by a Fabric Management command (GPSC). In an FCAL/N2N topology, port speed is based on the HBA link-rate. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

| * [SCSI] enable clustering for tmscsimGuennadi Liakhovetski2006-10-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | following an email from John Adams <johna@onevista.com> to me with a patch to enable tmscsim to use blocks up to 1MB and a discussion on linux-scsi, below is a patch to enable clustering for tmscsim. I made it switchable with a module parameter, with default "enable" - in case somebody gets problems with it. Unfortunately, I was not able to check if this alone lets you use any bigger blocks with a tape, as my tape seems to only support 1 block size - only "mt setblk 1" is successful, any other value fails. OTOH, testing on a P-133 showed that enabling clustering alone improves throughput by 10% and reduces CPU load by another 10%, so, seems a worthy thing to do. As for setting max_sectors, that might become a separate patch... Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

| * [SCSI] megaraid: Use the proper type to hold the irq number.Eric W. Biederman2006-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When testing on a Unisys machine it was discovered that the megaraid driver would not initialize as it was requesting irq 162 instead of irq 1442 it was assigned. The problem was the irq number had been truncated by being stored in an unsigned char. This patches fixes that problem and the driver now appears to work. The ioctl interface appears fundamentally broken as it exports the irq number to user space in an unsigned char. Signed-off-by: Eric W.

Set command timeout as specified by the SCSI layer rather than hardcode it to 30 seconds.

| * [SCSI] sg: fixes for large page_sizeDouglas Gilbert2006-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This sg driver patch addresses the problem with larger page sizes reported by Brian King in this post: http://marc.theaimsgroup.com/?l=linux-scsi&m=115867718623631&w=2 Some other related matters are also addressed. Some of these prevent oopses when the SG_SCATTER_SZ or scatter_elem_sz are set to inappropriate values. The scatter_elem_sz has been tested up to 4 MB which should make the largest data transfer with one SCSI command, 32 MB less one block, achievable with a relatively small number of elements in the scatter gather list. ChangeLog: - add scatter_elem_sz boot time parameter and sysfs module parameter that is initialized to SG_SCATTER_SZ - the driver will then adjust scatter_elem_sz to be the max(given(scatter_elem_sz), PAGE_SIZE) It will also round it up, if necessary, to be a power of two - clean up sg.h header, correct bad urls and some statements that are no longer valid - make the def_reserved_size sysfs module attribute writable Signed-off-by: Douglas Gilbert <dougg@torque.net> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
