Without a quirk they report a wrong button set and the x/y coordinates through ABS_Z/ABS_RX, confusing the higher levels (most notably X.Org's evdev driver). Device id 0x003 covers models 1900, 2150, and 2700 [1] though testing could only be performed on a model 1900.

According to NCR developers, the devices get confused when queried for reports in a standard way, rendering them unusable. NCR is shipping application called "RPSL" that can be used to drive these devices through hiddev, under the assumption that in-kernel driver doesn't perform initial report query. If it does, neither in-kernel nor hiddev-based driver can operate with these devices any more. Introduce a quirk that skips the report query for all NCR devices. The previous NOGET quirk was wrong and had been introduced because I misunderstood the nature of brokenness of these devices. Signed-off-by: Jiri Kosina <jkosina@suse.cz>

| * | | [SCSI] zfcp: Remove flag ZFCP_STATUS_FSFREQ_TMFUNCNOTSUPPChristof Schmitt2009-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The flag ZFCP_STATUS_FSFREQ_TMFUNCNOTSUPP is never set and hence can be removed. This is a leftover from the time when zfcp had to decide whether the target supports a "logical unit reset" or not. Nowadays, the SCSI midlayer calls the eh_device_reset_handler or the eh_target_reset_handler and zfcp simply maps this to a "logical unit reset" or a "target reset".

To prevent this, call the FC transport function fc_block_scsi_eh which waits until the rport leaves the BLOCKED state. This guarantees that communication is possible if the rport is ONLINE, or the SCSI devices will be removed if the rport state switches to NOT_PRESENT.

There is also no need in special treatment of ABORTED commands, so remove the ZFCP_STATUS_FSFREQ_ABORTED, the commands are then returned with DID_TRANSPORT_DISRUPTED. Also remove the ZFCP_STATUS_FSFREQ_RETRY: It is useless, no retry is happening in the FSF layer and nobody checks the state of this flag.

The SCSI midlayer will retry the commands and fc_remote_port_chkready will return the correct status code. But with the delay between calling scsi_done in softirq context and the call to fc_remote_port_delete from the workqueue, there is a window where zfcp returns DID_ERROR. This leads to SCSI error recovery which then leads to offline SCSI devices since all recovery actions will fail with the rport now being blocked. In this window, zfcp has to return DID_IMM_RETRY just as the FC transport class would do in fc_remote_port_chkready for the blocked fc_rport. As soon as the fc_rport is BLOCKED, fc_remote_port_chkready will do the right thing. Additionally, there are two more cases to catch in zfcp_scsi_queuecommand: - After the port has been opened, the unit has to be opened. During this period I/O has to be retried. This can also be handled with DID_IMM_RETRY. - If the access to the unit fails, but the port is good, then this single unit cannot be accessed and I/O to this unit has to fail without involving the FC transport class.

| * | | [SCSI] fcoe: allow SCSI-FCP to be processed directly in softirq contextChris Leech2009-12-04

This preserves the queuing to threads for scaling out receive processing to multiple CPUs, but allows FCoE-aware multi-queue network drivers that direct frames to the originating CPUs to handle FCP processing with less scheduling latency. Only FCP is handled directly, because libfc makes use of mutexes in ELS handling routines. The bulk of this change is just moving the FCoE receive processing out of the receive thread function, leaving behind just the thread and queue management.
