The ASIC block is shared between two HFIs. Individual devices should not initialize registers there. Retain the power-on values. Individual users set registers as needed with one exception. Clear sbus fast mode on "slow" calls. Reviewed-by:

Fix 3 memory leaks reported by the LeakCheck tool in the KEDR framework. The following resources were allocated memory during their respective initializations but not freed during cleanup: 1. SDMA map elements 2. PIO map elements 3. HW send context to SW index map This patch fixes the memory leaks by freeing the allocated memory in the cleanup path. Reviewed-by:

The LedInfo SMA attribute is redefined to control the LED beaconing state machine instead of the LED directly. In accordance, we now return the state of LED beaconing, represented by whether the beaconing timer is active, instead of the state of the LED itself for SMA queries Get(LedInfo) and Get(PortInfo). While we are at it, we fix the beaconing timer control code so that the state of the timer is accurately updated. Reviewed-by:

This patch tests the interrupt registers when the driver has no access to its upstream component. In this case, it is highly likely that it is running in a virtual machine (eg, Qemu-kvm guest). If the interrupt registers are not mapped properly by the virtual machine monitor, an error message will be printed and the probing will be terminated. This will help the user identify the issue. On the other hand, if the driver is running in a host or has access to its upstream component in some other VM, it will do nothing. Reviewed-by:

When the hfi1 device is assigned to a VM (eg KVM), the hfi1 driver has no access to the upstream component and therefore cannot use it to perform some operations, such as secondary bus reset. As a result, the hfi1 driver cannot perform the pcie Gen3 transition. Instead, those operation should be done in the host environment, preferrably done during the Option ROM initialization. Similarly, the hfi1 driver cannot support ASPM and tune the pcie capability under this circumstance. Reviewed-by:

There is a header size counter in both the QP struture and the txreq structure. The counter in the txreq structure is not updated properly for RC and UC queue pairs with GRH enabled, and thus causing SDMA send to fail. This patch fixes the RC and UC path. Reviewed-by:

The lkey_table_size driver specific parameter value is used before its value is sanity checked and restricted to RVT_MAX_LKEY_TABLE_BITS. This causes a vmalloc allocation failure for large values. Fix this by moving the value check before the first usage of the value. Reviewed-by:

A cp or cat of /sys/kernel/debug/hfi1/hfi1_0/port1counters produces the following message: hfi1 0000:81:00.0: hfi1_0: index not supported hfi1 0000:81:00.0: hfi1_0: read_cntrs does not support indexing Fix by removing the file position logic and the associated messages and make the file positioning the responsibility of the caller. The port counter read function argument is changed to the per port data structure since the counters are relative to the port and not the device. Reviewed-by:
