This patch adds function to print the pending frame details before returning failure from the reset routine. It also exposes a new variable megasas_dbg_lvl that allows the user to set the debug level for logging. Signed-off-by:

This patch adds function pointer to invoke disable interrupt for xscale and ppc IOP based controllers. Removes old implementation that checks for controller type in megasas_disable_intr. Signed-off-by:

This patch removes duplicated code in frame calculation & adds megasas_get_frame_count() that also takes into account the number of frames that can be contained in the Main frame. FW uses the frame count to pull sufficient number of frames from host memory. Signed-off-by:

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:

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:

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:

This is from RHEL4. I do not have any info from our bugzilla. All I could find was something like this thread http://lkml.org/lkml/2005/1/7/346 Report lun for linux does not work. It may be our lun format code or it may be the device. It is probably not worth it to add anything special for this device, so the patch just adds BLIST_NOREPORTLUN. Signed-off-by:

A new device (id 0x8650, nickname 'yosemite') support is added. It's basically the same, except for following items: - mapping of id and lun by firmware - special handling for some commands in interrupt routine - change of internal copy function for these special commands - different reset handling code - different shutdown notification command Signed-off-by:

Comment says "Read high byte first as some registers increment..." but code doesn't guarantee that, I think: return ((ahd_inb(ahd, port+1) << 8) | ahd_inb(ahd, port)); Compiler can reorder it. Make the order explicit. Signed-off-by:

gcc 4.1 with some extra warnings show the following: drivers/scsi/ipr.c:6361: warning: comparison of unsigned expression < 0 is always false drivers/scsi/ipr.c:6385: warning: comparison of unsigned expression < 0 is always false drivers/scsi/ipr.c:6415: warning: comparison of unsigned expression < 0 is always false The problem is that rc is of the type u32, which can never be smaller than zero, therefore all three error handling checks get useless. This patch changes it to a normal int, because all usages / all functions it get used with expect an int. Signed-off-by:

another signdness warning from gcc 4.1 drivers/scsi/osst.c:5154: warning: comparison of unsigned expression < 0 is always false The problem is that blk is defined as unsigned, but all usages of it are normal int cases. osst_get_frame_position() and osst_get_sector() return ints and can return negative values. If blk stays an unsigned int, the error check is useless. Signed-off-by:

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:
