* sched: simplify move_tasks()Peter Williams2007-08-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The move_tasks() function is currently multiplexed with two distinct capabilities: 1. attempt to move a specified amount of weighted load from one run queue to another; and 2. attempt to move a specified number of tasks from one run queue to another. The first of these capabilities is used in two places, load_balance() and load_balance_idle(), and in both of these cases the return value of move_tasks() is used purely to decide if tasks/load were moved and no notice of the actual number of tasks moved is taken. The second capability is used in exactly one place, active_load_balance(), to attempt to move exactly one task and, as before, the return value is only used as an indicator of success or failure. This multiplexing of sched_task() was introduced, by me, as part of the smpnice patches and was motivated by the fact that the alternative, one function to move specified load and one to move a single task, would have led to two functions of roughly the same complexity as the old move_tasks() (or the new balance_tasks()). However, the new modular design of the new CFS scheduler allows a simpler solution to be adopted and this patch addresses that solution by: 1. adding a new function, move_one_task(), to be used by active_load_balance(); and 2. making move_tasks() a single purpose function that tries to move a specified weighted load and returns 1 for success and 0 for failure. One of the consequences of these changes is that neither move_one_task() or the new move_tasks() care how many tasks sched_class.load_balance() moves and this enables its interface to be simplified by returning the amount of load moved as its result and removing the load_moved pointer from the argument list. This helps simplify the new move_tasks() and slightly reduces the amount of work done in each of sched_class.load_balance()'s implementations. Further simplification, e.g. changes to balance_tasks(), are possible but (slightly) complicated by the special needs of load_balance_fair() so I've left them to a later patch (if this one gets accepted). NB Since move_tasks() gets called with two run queue locks held even small reductions in overhead are worthwhile.

* sched: reorder update_cpu_load(rq) with the ->task_tick() callIngo Molnar2007-08-09
| | | | | | | | | Peter Williams suggested to flip the order of update_cpu_load(rq) with the ->task_tick() call. This is a NOP for the current scheduler (the two functions are independent of each other), ->task_tick() might create some state for update_cpu_load() in the future (or in PlugSched).

It went like this: 1. extra space was allocated at aha152x_scdata for mirroring scsi_cmnd members. 2. At aha152x_internal_queue() every not check_condition (REQUEST_SENSE) command was copied to above members in case of error. 3. At busfree_run() in the DONE_CS phase if a Status of SAM_STAT_CHECK_CONDITION was detected. The command was re-queued Internally using aha152x_internal_queue(,,check_condition,) The old command members are over written with the REQUEST_SENSE info. 4. At busfree_run() in the DONE_CS phase again. If it is a check_condition command, info was restored from mirror made at first call to aha152x_internal_queue() (see 2) and the command is completed. What I did is: 1. Allocate less space in aha152x_scdata only for the 16-byte original command. (which is actually not needed by scsi-ml anymore at this stage. But this is to much knowledge of scsi-ml) 2. If Status == SAM_STAT_CHECK_CONDITION, then like before re-queue a REQUEST_SENSE command. But only now save original command members. (Less of them) 3. In aha152x_internal_queue(), just like for Reset, use the check_condition hint to set differently the working members. execute the command. 4. At busfree_run() in the DONE_CS phase again. restore needed members. While at it. This patch fixes a BUG. Old code when sending a REQUEST_SENSE for a failed command. Would than return with cmd->resid == 0 which was the status of the REQUEST_SENSE. The failing command resid was lost. And when would resid be interesting if not on a failing command?

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | What Reset code was doing: Save command's important/dangerous Info on stack. NULL those members from scsi_cmnd. Issue a Reset. wait for it to finish than restore members and return. What I do is save or NULL nothing. But use the "resetting" hint in aha152x_internal_queue() to NULL out working members and leave struct scsi_cmnd alone.

But here it is used directly on status which means 0x1 which is an undefined bit in the standard. And is a status that will never return from a target. - in busfree_run at the DONE_SC phase we have 3 distinct operation: 1-if(DONE_SC->SCp.phase & check_condition) The REQUEST_SENSE command return. - Restore original command - Than continue to operation 3. 2-if(DONE_SC->SCp.Status==SAM_STAT_CHECK_CONDITION) A regular command returned with a status. - Internally re-Q a REQUEST_SENSE. - Do not do operation 3. 3- - Complete the command and return it to scsi-ml So the 0x2 in both these operations (1,2) means the scsi check-condition status, hence SAM_STAT_CHECK_CONDITION - Here the code asks about !(DONE_SC->SCp.Status & not_issued) but "not_issued" is an enum belonging to the "phase" member and not to the Status returned from target. The reason this works is because not_issued==1 and Also CHECK_CONDITION==1 (remember from hunk 1). So actually the code was asking !(DONE_SC->SCp.Status & CHECK_CONDITION). Which means "Has the status been read from target yet?" Staus is read at status_run(). "not_issued" is cleared in seldo_run() which is usually earlier than status_run(). So this patch does nothing as far as assembly is concerned but it does let the reader understand what is going on.

| * | [SCSI] ESP: Revert ESP_BUS_TIMEOUT back down to 250David Miller2007-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts d73f5222a618a91452d41c29f5996ce3d9c63673 The bug that made us increase ESP_BUS_TIMEOUT to 275 turned out to be a memset bug on 32-bit sparc. It is better to put this back at the correct timeout value than to leave it increased when there is no reason for doing so. Signed-off-by: David S.

| * | [SCSI] aic7xxx: cap maxsync according to correct card limitsJames Bottomley2007-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | Not doing this can cause cards less than u160 capable to send out PPR offers to devices they can't then deliver on ... causing some devices to get a bit confused. Fix by capping the start syncrate at the appropriate level according to the card capabilities. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

| * | [SCSI] bsg: update sg_io_v4 structureFUJITA Tomonori2007-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This updates sg_io_v4 structure (based on Doug's RFC, release 1.3). The major changes are: - add dout_resid field - increase tag size to 64 bits to comply with SAM-4 and SRP - add dout_iovec_count and din_iovec_count dout_iovec_count and din_iovec_count aren't supported now. I'm not sure whether they will be supported or not but they were added for the possible future changes.
