Calling scsi_remove_device later lets the sd driver issue a SYNCHRONIZE_CACHE command. This command stays on the "stopped" request requeue because the SCSI device is blocked. Fix this by first removing the scsi and fc hosts which removes all scsi devices and do not use scsi_remove_device.

| | | | | | | | | | | | | | | | firmware to ACK. Following a diag_reset, a request to send an ioc_init is timing out. The timeout occurred within the HANDSHAKE logic while waiting on firmware to acknowledge that the driver had wrote to the doorbell register. This was root caused to a logic timeout in the firmware code. The proposed solution is for the driver to call the udelay instead of msleep API in function where its looping reading the interrupt status. In addition to this change, there were two additional cases where we deleted the clearing interrupt status outside handshake context.

This code will create a link list of pending target resets if there is no more available request in the hipriority request queue. The list is stored in ioc->delayed_tr_list. (2) All callback handler return type is changed from void to u8. Now _base_interrupt will check for return type of callback handlers to take decision of message frame is already freed or not. In genral, Return 1 meaning mf should be freed from _base_interrupt 0 means the mf is freed from function.

The modifications are in _base_allocate_memory_pools. Also create a seperate pool of memory for internal commands located near the same region of memory. The pool of high priority message frames is restriced by the facts->HighPriorityCredit. 2) Create additional API for accessing request message frames. New function mpt2sas_base_get_smid_hpr is for highpriority request. New function mpt2sas_base_get_smid_scsiio for SCSI_IO, passing in the scsi command pointer. The mpt2sas_base_get_smid function is for requesting internal commands. 3) Added new function _base_get_cb_idx to obtain the callback index from one of the three pools of request message frames. 4) Removed wrapper functions _scsih_scsi_lookup_set and _scsih_scsi_lookup_getclear. These were removed because this handling was moved into mpt2sas_base_get_smid_scsiio and mpt2sas_base_free_smid. 5) The function mpt2sas_base_free_smid is modified so the request message frames are put back on one of the three pools of request message frames.

Current drivers do not program this register based on architecture type (e.g. x86 = 4K, IA64 = 16K) and by choice lets device use the defaults. So while mapping connection context memory (doorebll registers), driver has to match page size used by the device.

The last register in a channel can be skipped since it's read-only (at offset 0x18).

This combines them. [Ralf: The issue was originally introduced by commit be4894196d79455f420dd7bb78be7dc73bec115c (linux-mips.org) rsp. 033890b084adfa367c544864451d7730552ce8bf (kernel.org). The original intention of the code was to initialize .flags with both flags ored together. The broken C code as actually implemented will be compiled by an equally broken gcc to use only the last initialization, that is IRQF_PERCPU which means this turned into an SMTC bug for 2.6.23 and newer.] The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ identifier I, s, fld; position p0,p; expression E; @@ struct I s =@p0 { ... .fld@p = E, ...}; @s@ identifier I, s, r.fld; position r.p0,p; expression E; @@ struct I s =@p0 { ... .fld@p = E, ...}; @script:python@ p0 << r.p0; fld << r.fld; ps << s.p; pr << r.p; @@ if int(ps[0].line)!=int(pr[0].line) or int(ps[0].column)!=int(pr[0].column): cocci.print_main(fld,p0) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
