Currently, only MTUs of VLs 0-7 are checked when calculating the maximum VL MTU which is used to set the port MTU capability in DCC_CFG_PORT_CONFIG CSR This can cause a port MTU capability to be set to 0 if MTUs of VLs 0-7 is 0 This would affect the VL15 traffic. Reviewed-by:

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:

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.

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.
