3 Older Version : 00.00.03.16
|
|
|
|
1. Rollback the sense info implementation
|
|
Sense buffer ptr data type in the ioctl path is reverted back
|
|
to u32 * as in previous versions of driver.
|
|
|
|
2. Fixed the driver frame count.
|
|
When Driver sent wrong frame count to firmware. As this
|
|
particular command is sent to drive, FW is seeing continuous
|
|
chip resets and so the command will timeout.
|
|
|
|
3. Add the new controller(1078DE) support to the driver
|
|
and Increase the max_wait to 60 from 10 in the controller
|
|
operational status. With this max_wait increase, driver will
|
|
make sure the FW will finish the pending cmd for KDUMP case.

|
|
|
1. Added module parameter "poll_mode_io" to support for "polling"
|
|
(reduced interrupt operation). In this mode, IO completion
|
|
interrupts are delayed. At the end of initiating IOs, the
|
|
driver schedules for cmd completion if there are pending cmds
|
|
to be completed. A timer-based interrupt has also been added
|
|
to prevent IO completion processing from being delayed
|
|
indefinitely in the case that no new IOs are initiated.

|
|
|
1. Setting the max_sectors_per_req based on max SGL supported by the
|
|
FW. Prior versions calculated this value from controller info
|
|
(max_sectors_1, max_sectors_2). For certain controllers/FW,
|
|
this was resulting in a value greater than max SGL supported
|
|
by the FW. Issue was first reported by users running LUKS+XFS
|
|
with megaraid_sas. Thanks to RB for providing the logs and
|
|
duplication steps that helped to get to the root cause of the
|
|
issue. 2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from
|
|
10. FW may take a max of 60 seconds to respond to the INIT
|
|
cmd.

1. When MegaSAS driver receives reset call from OS, driver waits in reset
|
|
routine for max 3 minutes for all pending command completion. Now driver will
|
|
call completion routine every 5 seconds from the reset routine instead of
|
|
waiting for depending on cmd completion from isr path.

change there is no need of memory manager in the driver code

It does, but the DMA API was expanded to cope with this exact case, so
|
|
use dma_alloc_coherent() directly in the megaraid code instead. The dev
|
|
is just &pci_dev->dev.

|
|
3. SYNCHRONIZE_CACHE is not supported by FW and thus blocked by driver.
|
|
4. Hibernation support added
|
|
5. Performing diskdump while running IO in RHEL 4 was failing. Fixed.

i. Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors

The driver now waits for 10 seconds to elapse instead of 5 (as in

previous release) to resume IO.

|
i. Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
|
|
|
|
Fix: The driver is now throttling IO.
|
|
Checks added in megasas_queue_command to know if FW is able to
|
|
process commands within timeout period. If number of retries
|
|
is 2 or greater,the driver stops sending cmd to FW temporarily. IO is
|
|
resumed if pending cmd count reduces to 16 or 5 seconds has elapsed
|
|
from the time cmds were last sent to FW.
|
|
|
|
ii. FW enables WCE bit in Mode Sense cmd for drives that are configured
|
|
as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical
|
|
Disks are exposed with WCE=1. User is advised to enable Write Back
|
|
mode only when the controller has battery backup. At this time
|
|
Synhronize cache is not supported by the FW. Driver will short-cycle
|
|
the cmd and return success without sending down to FW.

1. Added new memory management module to support the IOCTL memory allocation. For IOCTL we try to allocate from the memory pool created during driver initialization. If mem pool is empty then we allocate at run time.
|
|
2. Added check in megasas_queue_command and dpc/isr routine to see if we have already declared adapter dead
|
|
(hw_crit_error=1). If hw_crit_error==1, now we donot accept any processing of pending cmds/accept any cmd from OS

Interrupt is enabled after required initialization is over.
|
|
This is done to ensure that driver is ready to handle interrupts when
|
|
it is generated by the controller.
