| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hi, Reading the Intel VSC and AHCI it seems like writing 0x302 is incorrect.

* | | | [PATCH] libata: implement dummy portTejun Heo2006-08-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <htejun@gmail.com>

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <uchang@tw.ibm.com>.

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.
