From 85d22bbf6787c240921539bba224eb221bfb8ee1 Mon Sep 17 00:00:00 2001 From: Mahesh Rajashekhara Date: Sat, 14 Jul 2012 18:18:51 +0530 Subject: [SCSI] aacraid: Series 7 Async. (performance) mode support - Series 7 Async. (performance) mode support added - New scatter/gather list format for Series 7 - Driver converts s/g list to a firmware suitable list for best performance on Series 7, this can be disabled with driver parameter "aac_convert_sgl" for testing purposes - New container read/write command structure for Series 7 - Fast response support for the SCSI pass-through path added - Async. status response buffer changes Signed-off-by: Mahesh Rajashekhara Signed-off-by: James Bottomley --- drivers/scsi/aacraid/commsup.c | 22 +++++++++++++--------- 1 file changed, 13 insertions(+), 9 deletions(-) (limited to 'drivers/scsi/aacraid/commsup.c') diff --git a/drivers/scsi/aacraid/commsup.c b/drivers/scsi/aacraid/commsup.c index 906a5013eda..1be0776a80c 100644 --- a/drivers/scsi/aacraid/commsup.c +++ b/drivers/scsi/aacraid/commsup.c @@ -136,6 +136,7 @@ int aac_fib_setup(struct aac_dev * dev) i < (dev->scsi_host_ptr->can_queue + AAC_NUM_MGT_FIB); i++, fibptr++) { + fibptr->flags = 0; fibptr->dev = dev; fibptr->hw_fib_va = hw_fib; fibptr->data = (void *) fibptr->hw_fib_va->data; @@ -240,11 +241,11 @@ void aac_fib_init(struct fib *fibptr) { struct hw_fib *hw_fib = fibptr->hw_fib_va; + memset(&hw_fib->header, 0, sizeof(struct aac_fibhdr)); hw_fib->header.StructType = FIB_MAGIC; hw_fib->header.Size = cpu_to_le16(fibptr->dev->max_fib_size); hw_fib->header.XferState = cpu_to_le32(HostOwned | FibInitialized | FibEmpty | FastResponseCapable); - hw_fib->header.SenderFibAddress = 0; /* Filled in later if needed */ - hw_fib->header.ReceiverFibAddress = cpu_to_le32(fibptr->hw_fib_pa); + hw_fib->header.u.ReceiverFibAddress = cpu_to_le32(fibptr->hw_fib_pa); hw_fib->header.SenderSize = cpu_to_le16(fibptr->dev->max_fib_size); } @@ -259,7 +260,6 @@ void aac_fib_init(struct fib *fibptr) static void fib_dealloc(struct fib * fibptr) { struct hw_fib *hw_fib = fibptr->hw_fib_va; - BUG_ON(hw_fib->header.StructType != FIB_MAGIC); hw_fib->header.XferState = 0; } @@ -370,7 +370,7 @@ int aac_queue_get(struct aac_dev * dev, u32 * index, u32 qid, struct hw_fib * hw entry->size = cpu_to_le32(le16_to_cpu(hw_fib->header.Size)); entry->addr = hw_fib->header.SenderFibAddress; /* Restore adapters pointer to the FIB */ - hw_fib->header.ReceiverFibAddress = hw_fib->header.SenderFibAddress; /* Let the adapter now where to find its data */ + hw_fib->header.u.ReceiverFibAddress = hw_fib->header.SenderFibAddress; /* Let the adapter now where to find its data */ map = 0; } /* @@ -450,7 +450,7 @@ int aac_fib_send(u16 command, struct fib *fibptr, unsigned long size, */ hw_fib->header.SenderFibAddress = cpu_to_le32(((u32)(fibptr - dev->fibs)) << 2); - hw_fib->header.SenderData = (u32)(fibptr - dev->fibs); + hw_fib->header.Handle = (u32)(fibptr - dev->fibs) + 1; /* * Set FIB state to indicate where it came from and if we want a * response from the adapter.
