Correctly reduce the number of VLs when limited by the number of SDMA engines. The hardware has multiple egress mechanisms, SDMA and pio, and multiples of those. These mechanisms are chosen using the VL (8) The fix corrects a panic issue with one of the platforms that doesn't have enough SDMA (4) mechanisms for the typical number of VLs. Reviewed-by:

Add aeth name syndrome decode to enhance debugging. The IBTA RC ACK contains an ACK extended transport header. Part of that header is the syndrome field that qualifies the RC ACK as an ACK, NAK, or RNR NAK. Without the patch here is the syndrome decode: aeth syn 0x00 Here is the decode with the fix: aeth syn 0x00 ACK Reviewed-by:

hfi1 driver build fails with the following error: In function ‘handle_receive_interrupt’: error: implicit declaration of function ‘skip_rcv_packet’ [-Werror=implicit-function-declaration] last = skip_rcv_packet(&packet, thread); ^ This is due to the inclusion of the skip_rcv_packet() in the CONFIG_PRESCAN_RXQ ifdef block. This function is independent of CONFIG_PRESCAN_RXQ and should be outside this block. Fixes: 82c2611d ("staging/rdma/hfi1: Handle packets with invalid RHF on context 0") Reviewed-by: -

A link downgrade can race with link up. Avoid the race in two ways. First, by having the downgrade application logic take the link state mutex for all of its checking. Second, by waiting for the link to move out of the going up state. Reviewed-by:

Using fence->status to determine whether or not there are callbacks remaining on the sync_fence is racy since fence->status may have been decremented to 0 on another CPU before fence_check_cb_func() has completed. By unconditionally calling fence_remove_callback() for each fence in the sync_fence, we guarantee that each callback has either completed (since fence_remove_callback() grabs the fence lock) or been removed.

Pass index of vif instead of hif_drv. wilc_get_vif_idx is used to get correct index of vif. In the handler function handle_set_wfi_drv_handler, use vif instead of hif_drv, and use hif_drv_handler->handler instead of hif_drv when deinitialize wilc device. Signed-off-by:

We now have vif index in all functions related with host interface thread. wilc_get_vif_idx and wilc_get_vif_from_idx are added to get id and vif respectively. Relace get_id_from_handler with wilc_get_vif_idx and get_handler_from_id with wilc_get_vif_from_idx. Remove unused function get_handler_from_id as well. We get vif where wilc_get_vif_from_idx is called, so pass vif to msg.vif. There are two get_id_from_handler left. They will be removed in later patch. Signed-off-by:

In the first patch, we sent vif to hostIFthread. we can use vif instead of drv in the all functions which handle the commands from cfg operations. Change first argument host_if_drv with wilc_vif and use hif_drv of wilc_vif. Pass vif to the functions as well. In case of timer callback functions, set vif to the data and use vif instead of hif_drv. Lastly, initialize u32RcvdAssocRespInfoLen since changing hif_drv with vif causes one uninitialied build warning. Now we have vif that currently being used so we can use interface index of wilc_vif to send to wilc device. Signed-off-by:

We will pass vif, which is currently being used as net_device, instead of hif_dev. This is the first step to use index of vif to pass to the driver. Add new argument vif to all the functions that send message to hostIFthread and set vif to msg.vif. As a result, hostIfthread will get vif. In later patch, we will remove drv of host_if_msg and use vif instead of it. Signed-off-by:
