2006-08-10[PATCH] libata: use dummy port for stolen legacy portsTejun Heo2-26/+17
Use dummy port for stolen legacy ports. This makes ap->port_no always equal ap->hard_port_no. Signed-off-by: Tejun Heo <[email protected]>
2006-08-10[PATCH] libata: implement dummy portTejun Heo1-10/+51
Implement dummy port which can be requested by setting appropriate bit in probe_ent->dummy_port_mask. The dummy port is used as placeholder for stolen legacy port. This allows libata to guarantee that index_of(ap) == ap->port_no == actual_device_port_no, and thus to remove error-prone ap->hard_port_no. As it's used only when one port of a legacy controller is reserved by some other entity (e.g. IDE), the focus is on keeping the added *code* complexity at minimum, so dummy port allocates all libata core resources and acts as a normal port. It just has all dummy port_ops. This patch only implements dummy port. The following patch will make libata use it for stolen legacy ports. Signed-off-by: Tejun Heo <[email protected]>
2006-08-10[PATCH] libata: rework legacy handling to remove much of the cruftAlan Cox3-96/+100
Kill host_set->next Fix simplex support Allow per platform setting of IDE legacy bases Some of this can be tidied further later on, in particular all the legacy port gunge belongs as a PCI quirk/PCI header decode to understand the special legacy IDE rules in the PCI spec. Longer term Jeff also wants to move the request_irq/free_irq out of core which will make this even cleaner. tj: folded in three followup patches - ata_piix-fix, broken-arch-fix and fix-new-legacy-handling, and separated per-dev xfermask into separate patch preceding this one. Folded in fixes are... * ata_piix-fix: fix build failure due to host_set->next removal * broken-arch-fix: add missing include/asm-*/libata-portmap.h * fix-new-legacy-handling: * In ata_pci_init_legacy_port(), probe_num was incorrectly incremented during initialization of the secondary port and probe_ent->n_ports was incorrectly fixed to 1. * Both legacy ports ended up having the same hard_port_no. * When printing port information, both legacy ports printed the first irq.

2006-08-10[PATCH] libata: implement per-dev xfermaskTejun Heo1-29/+11
Implement per-dev xfermask. libata used to determine xfermask per-port - the fastest mode of the slowest device on the port. This patch enables per-dev xfermask. Original patch is from Alan Cox <[email protected]>. The following changes are made by me. * simplex warning message is added * remove disabled device handling code which is never invoked (originally for choosing port-wide lowest PIO mode) Cc: Alan Cox <[email protected]> Signed-off-by: Tejun Heo <[email protected]>

2006-08-09[PATCH] libata: clear sdev->locked on door lock failureTejun Heo1-0/+13
SCSI EH locks door if sdev->locked is set. Sometimes door lock command fails continuously (e.g. when medium is not present) and as libata uses EH to acquire sense data, this easily creates a loop where a failed lock door invokes EH and EH issues lock door on completion. This patch clears sdev->locked on door lock failure to break this loop. This problem has been spotted and diagnosed by Unicorn Chang <[email protected]>.

2006-08-09[PATCH] libata: Add support for SATA attachment to SAS adaptersBrian King3-1/+151
The following patch enhances libata to allow SAS device drivers to utilize libata to talk to SATA devices. It introduces some new APIs which allow libata to be used without allocating a virtual scsi host. New APIs: ata_sas_port_alloc - Allocate an ata_port ata_sas_port_init - Initialize an ata_port (probe device, etc) ata_sas_port_destroy - Free an ata_port allocated by ata_sas_port_alloc ata_sas_slave_configure - configure scsi device ata_sas_queuecmd - queue a scsi command, similar to ata_scsi_queuecomand These new APIs can be used either directly by a SAS LLDD or could be used by the SAS transport class. Possible usage for a SAS LLDD would be: scsi_scan_host target_alloc ata_sas_port_alloc slave_alloc ata_sas_port_init slave_configure ata_sas_slave_configure Commands received by the LLDD for SATA devices would call ata_sas_queuecmd. Device teardown would occur with: slave_destroy port_disable target_destroy ata_sas_port_destroy Signed-off-by: Brian King <[email protected]> Signed-off-by: Jeff Garzik <[email protected]>

2006-08-06[SCSI] qla2xxx: Fix to allow to reset devices using sg interface (sg_reset).Vladislav Bolkhovitin1-9/+3
Currently it is impossible to reset provided by Qlogic QLA2xxx driver SCSI devices externally using corresponding sg devices, particularly via sg_reset utility, because qla2xxx driver in qla2xxx_eh_device_reset() function checks if the input scsi_cmnd has its private data (CMD_SP()) attached. Then the found pointer isn't used anywhere inside of qla2xxx_eh_device_reset(). If the RESET request comes from sg device, it doesn't have such private data. The attached patch removes check for non-NULL CMD_SP() from qla2xxx_eh_device_reset(), hence allows to reset QLA2xxx's devices using corresponding sg devices. AV: change applies to bus/host reset handlers as well.
