Just enough infrastructure to get raw-bitstream writes operational. With a common decode implementation in libsas. SAS-2 support is deferred as SFF-8485 remains at v0.7 [1]. Read support and the "non-raw" tx registers are deferred until the general approach is accepted. For future patches it might be useful to register a 'sgpio' interface in sysfs for all local phys to accept IBPI commands like "identify" or "fail". Although, the driver has no way of verifying if phy0 is routed to sgpio-device0. Until then this interface just uses the sas_host bsg device as shown in patch1. -- Dan [1]: http://marc.info/?l=linux-scsi&m=130693695829154&w=2 --- Dan Williams (3): libsas: sgpio write support isci: fix sgpio register definitions isci: initial sgpio write support drivers/scsi/isci/host.c | 69 ++++++++++++++++++++ drivers/scsi/isci/host.h | 15 ++++ drivers/scsi/isci/init.c | 3 + drivers/scsi/isci/registers.h | 122 +----------------------------------- drivers/scsi/libsas/sas_host_smp.c | 103 ++++++++++++++++++++++++++++++ include/scsi/libsas.h | 11 +++ include/scsi/sas.h | 8 ++ 7 files changed, 211 insertions(+), 120 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
