| Description: | |
| The optional "hw_counters" subdirectory can be under either the | |
| parent device or the port subdirectories or both. If present, | |
| there are a list of counters provided by the hardware. They may | |
| match some of the counters in the counters directory, but they | |
| often include many other counters. In addition to the various | |
| counters, there will be a file named "lifespan" that configures | |
| how frequently the core should update the counters when they are | |
| being accessed (counters are not updated if they are not being | |
| accessed). The lifespan is in milliseconds and defaults to 10 | |
| unless set to something else by the driver. Users may echo a | |
| value between 0-10000 to the lifespan file to set the length | |
| of time between updates in milliseconds. | |

| one device of each type (for switch port 0). | |

| Description: | |
| The sysfs iov directory is used to manage and examine the port | |
| P_Key and guid paravirtualization. This directory is added only | |
| for the master -- slaves do not have it. | |
| Under iov/ports, the administrator may examine the gid and P_Key | |
| tables as they are present in the device (and as are seen in the | |
| "network view" presented to the SM). | |
| The "pkeys" and "gids" subdirectories contain one file for each | |
| entry in the port's P_Key or GID table respectively. For | |
| example, ports/1/pkeys/10 contains the value at index 10 in port | |
| 1's P_Key table. | |
| ======================= ========================================== | |
| gids/<n>: (RO) The physical port gids n = 0..127 | |
| admin_guids/<n>: (RW) Allows examining or changing the | |
| administrative state of a given GUID | |
| n = 0..127 | |
| pkeys/<n>: (RO) Displays the contents of the physical | |
| key table n = 0..126 | |
| mcgs/: (RO) Multicast group table | |
| <m>/gid_idx/0: (RO) Display the GID mapping m = 1..2 | |
| <m>/pkey_idx/<n>: (RW) Writable except for RoCE pkeys. | |
| m = 1..2, n = 0..126 | |
| Under the iov/<pci slot number> | |
| directories, the admin may map the index | |
| numbers in the physical tables (as under | |
| iov/ports) to the paravirtualized index | |
| numbers that guests see. | |
| For example, if the administrator, for | |
| port 1 on guest 2 maps physical pkey | |
| index 10 to virtual index 1, then that | |
| guest, whenever it uses its pkey index | |
| 1, will actually be using the real pkey | |
| index 10. | |

| =============== ============================================== | |
| cpu_list: (RW) List of cpus for user-process to sdma | |
| engine assignment. | |
| vl: (RO) Displays the virtual lane (vl) the sdma | |
| engine maps to. | |
| =============== ============================================== | |
| This interface gives the user control on the affinity settings | |
| for the device. As an example, to set an sdma engine irq | |
| affinity and thread affinity of a user processes to use the | |
| sdma engine, which is "near" in terms of NUMA configuration, or | |
| physical cpu location, the user will do:: | |
| echo "3" > /proc/irq/<N>/smp_affinity_list | |
| echo "4-7" > /sys/devices/.../sdma3/cpu_list | |
| cat /sys/devices/.../sdma3/vl | |
| 0 | |
| echo "8" > /proc/irq/<M>/smp_affinity_list | |
| echo "9-12" > /sys/devices/.../sdma4/cpu_list | |
| cat /sys/devices/.../sdma4/vl | |
| 1 | |
| to make sure that when a process runs on cpus 4,5,6, or 7, and | |
| uses vl=0, then sdma engine 3 is selected by the driver, and | |
| also the interrupt of the sdma engine 3 is steered to cpu 3. | |
| Similarly, when a process runs on cpus 9,10,11, or 12 and sets | |
| vl=1, then engine 4 will be selected and the irq of the sdma | |
| engine 4 is steered to cpu 8. This assumes that in the above N | |
| is the irq number of "sdma3", and M is irq number of "sdma4" in | |
| the /proc/interrupts file. | |
