2 Current Version : 00.00.03.05
|
||||
3 Older Version : 00.00.03.04
|
||||
|
||||
i. PCI_DEVICE macro used
|
||||
|
||||
Convert the pci_device_id-table of the megaraid_sas-driver to the PCI_DEVICE-macro, to safe some lines.
|
||||
|
||||
- Henrik Kretzschmar <henne@nachtwindheim.de>
|
||||
ii. All compiler warnings removed
|
||||
iii. megasas_ctrl_info struct reverted to 3.02 release
|
||||
iv. Default value of megasas_dbg_lvl set to 0
|
||||
v. Removing in megasas_exit the sysfs entry created for megasas_dbg_lvl
|
||||
vi. In megasas_teardown_frame_pool(), cmd->frame was passed instead of
|
||||
cmd->sense to pci_pool_free. Fixed. Bug was pointed out by
|
||||

2 Current Version : 00.00.03.04
|
||||
3 Older Version : 00.00.03.03
|
||||
|
||||
i. Added Reboot notify
|
||||
ii. Reduced by 1 max cmds sent to FW from Driver to make the reply_q_sz same
|
||||
as Max Cmds FW can support

2 Current Version : 00.00.03.03
|
||||
3 Older Version : 00.00.03.02
|
||||
|
||||
i. Send stop adapter to FW & Dump pending FW cmds before declaring adapter dead.
|
||||
New varible added to set dbg level.
|
||||
ii. Disable interrupt made as fn pointer as they are different for 1068 / 1078
|
||||
iii. Frame count optimization. Main frame can contain 2 SGE for 64 bit SGLs and
|
||||
3 SGE for 32 bit SGL
|
||||
iv. Tasklet added for cmd completion
|
||||
v. If FW in operational state before firing INIT, now we send RESET Flag to FW instead of just READY. This is used to do soft reset.
|
||||
vi. megasas_ctrl_prop structure updated (based on FW struct)
|
||||
vii. Added print : FW now in Ready State during initialization

the double handling of data. There are two methods offered to remove the

redundant copy: 1) direct IO which uses the kernel kiobuf mechanism and

In terms of absolute speed mmap() is faster. If speed is not a concern,

indirect IO should be fine. Read the documentation for more information.
