* SCSI host lock push-downJeff Garzik2010-11-161-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Move the mid-layer's ->queuecommand() invocation from being locked with the host lock to being unlocked to facilitate speeding up the critical path for drivers who don't need this lock taken anyway. The patch below presents a simple SCSI host lock push-down as an equivalent transformation. No locking or other behavior should change with this patch. All existing bugs and locking orders are preserved. Additionally, add one parameter to queuecommand, struct Scsi_Host * and remove one parameter from queuecommand, void (*done)(struct scsi_cmnd *) Scsi_Host* is a convenient pointer that most host drivers need anyway, and 'done' is redundant to struct scsi_cmnd->scsi_done. Minimal code disturbance was attempted with this change. Most drivers needed only two one-line modifications for their host lock push-down.

* [SCSI] advansys: fix narrow board error pathHerton Ronaldo Krzesinski2010-05-011-14/+36
| | | | | | | | | | | | | Error handling on advansys_board_found is fixed, because it's buggy in the case we have an ASC_NARROW_BOARD set and failure happens on AscInitAsc1000Driver step: it was freeing items of wrong struct in the dvc_var union of struct asc_board, which could lead to an oops in the case we set some of the fields in struct of narrow board as code was choosing to always freeing wide board fields, and not everything was being freed/released properly.

* [SCSI] advansys: fix regression with request_firmware changeHerton Ronaldo Krzesinski2010-03-271-0/+8
| | | | | | | | | | | | | | | | | | | On newer kernels users of advansys module are reporting system hang when trying to load it without firmware files present. After looking closely at description on https://qa.mandriva.com/show_bug.cgi?id=53220, I think this is related to commit "[SCSI] advansys: use request_firmware". The problem is that after switch to request_firmware, asc_dvc->err_code isn't being set when firmware files aren't found or loading fails. err_code is used by the driver to judge if there was a fatal error or not, as can be seen for example on advansys_board_found, which will only return -ENODEV when err_code is set. Because err_code isn't being set when request_firmware fails, this is a change of behaviour of the code before request_firmware addition, making it continue to load and it fails later as the firmware wasn't really loaded.

* advansys fix on ISA-less configsAl Viro2008-11-301-0/+4
| | | | | | | | | | | | | | | | | | | The code if (shost->dma_channel != NO_ISA_DMA) free_dma(shost->dma_channel); in there is triggerable only if we have CONFIG_ISA (we only set ->dma_channel to something other than NO_ISA_DMA under #ifdef CONFIG_ISA). OTOH, free_dma() is not guaranteed to be there in absense of CONFIG_ISA. IOW, driver runs into undefined symbols on PCI-but-not-ISA configs (e.g. on frv) and it's a false positive. Fix: put the entire if () under #ifdef CONFIG_ISA; behaviour doesn't change and dependency on free_dma() disappears for !CONFIG_ISA.

* [SCSI] advansys: fix overrun_buf aligned bugFUJITA Tomonori2008-02-111-2/+11
| | | | | | | | | | | | | | | | | | | | | | struct asc_dvc_var needs overrun buffer to be placed on an 8 byte boundary. advansys defines struct asc_dvc_var: struct asc_dvc_var { ... uchar overrun_buf[ASC_OVERRUN_BSIZE] __aligned(8); The problem is that struct asc_dvc_var is placed on shost->hostdata. So if the hostdata is not on an 8 byte boundary, the advansys crashes. The hostdata is placed on a sizeof(unsigned long) boundary so the 8 byte boundary is not garanteed with x86_32. With 2.6.23 and 2.6.24, the hostdata is on an 8 byte boundary by chance, but with the current git, it's not. This patch removes overrun_buf static array and use kzalloc.

* [SCSI] advansys: Sort out irq number messMatthew Wilcox2007-10-121-198/+189
| | | | | | | | | | | | | | | | | | | The interrupt number was being stored in 4-5 different places, each with its own type, rules and usage. Fix this by keeping an unsigned int in the struct asc_board, and filling it in from the bus probe functions (since it's different for each of the four bus types). In order to do this, we have to allocate the Scsi_Host in the bus probe functions too. Then we can return an error from advansys_board_found, which requires a little rearranging of code (and removing of the err_code variable). Move the Wide Board flag setting into the PCI bus probe function. Split the AscGetChipIRQ function into three functions (one for each bus type that needs it) and add some commentary to explain what's going on. Also get rid of the AscSetChipIRQ function as we only ever set the interrupt number to the same value it already had.

The comment was wrong; scsi_done cannot enable interrupts. - All other places which queued an scp on the done list are error paths for queuecommand, and so we can just call asc_scsi_done() in queuecommand if we receive an error. - We no longer need to keep a list of done requests in advansys_interrupt Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] advansys: Remove a check for an impossible conditionMatthew Wilcox2007-10-121-19/+0

* [SCSI] advansys: Remove `waiting' queueMatthew Wilcox2007-10-121-177/+9
| | | | | | | | | If the adapter is busy, return the request to the midlayer rather than queueing it in the driver. asc_execute_queue() and asc_dequeue() become unused, and we don't need to print out stats on the waiting queue any more.
