2019-11-10libbpf: Support XDP_SHARED_UMEM with external XDP programMagnus Karlsson1-10/+17
Add support in libbpf to create multiple sockets that share a single umem. Note that an external XDP program need to be supplied that routes the incoming traffic to the desired sockets. So you need to supply the libbpf_flag XSK_LIBBPF_FLAGS__INHIBIT_PROG_LOAD and load your own XDP program.

2019-11-10libbpf: Add getter for program sizeToke Høiland-Jørgensen3-0/+9
This adds a new getter for the BPF program size (in bytes). This is useful for a caller that is trying to predict how much memory will be locked by loading a BPF object into the kernel.

2019-11-10libbpf: Add bpf_get_link_xdp_info() function to get more XDP informationToke Høiland-Jørgensen3-28/+67
Currently, libbpf only provides a function to get a single ID for the XDP program attached to the interface. However, it can be useful to get the full set of program IDs attached, along with the attachment mode, in one go. Add a new getter function to support this, using an extendible structure to carry the information. Express the old bpf_get_link_id() function in terms of the new function.

2019-11-10libbpf: Use pr_warn() when printing netlink errorsToke Høiland-Jørgensen2-6/+7
The netlink functions were using fprintf(stderr, ) directly to print out error messages, instead of going through the usual logging macros. This makes it impossible for the calling application to silence or redirect those error messages. Fix this by switching to pr_warn() in nlattr.c and netlink.c.

2019-11-10libbpf: Propagate EPERM to caller on program loadToke Høiland-Jørgensen1-16/+11
When loading an eBPF program, libbpf overrides the return code for EPERM errors instead of returning it to the caller. This makes it hard to figure out what went wrong on load. In particular, EPERM is returned when the system rlimit is too low to lock the memory required for the BPF program. Previously, this was somewhat obscured because the rlimit error would be hit on map creation (which does return it correctly). However, since maps can now be reused, object load can proceed all the way to loading programs without hitting the error; propagating it even in this case makes it possible for the caller to react appropriately (and, e.g., attempt to raise the rlimit before retrying).

2019-11-10libbpf: Unpin auto-pinned maps if loading failsToke Høiland-Jørgensen1-1/+8
Since the automatic map-pinning happens during load, it will leave pinned maps around if the load fails at a later stage. Fix this by unpinning any pinned maps on cleanup. To avoid unpinning pinned maps that were reused rather than newly pinned, add a new boolean property on struct bpf_map to keep track of whether that map was reused or not; and only unpin those maps that were not reused.

Here the change are: - When there is no support of CONFIG_TDP_GET_LEVELS_INFO, then instead of treating this as fatal error, treat this with number of config levels = 0, that means only base level 0 is present. - There is no support of mail box commands to get base frequencies or turbo frequencies.

To be consistant with the other frequency units, change the CLOS unit to MHz instead of ratios. Signed-off-by: Srinivas Pandruvada <[email protected]> Signed-off-by: Andy Shevchenko <[email protected]>
2019-11-07tools/power/x86/intel-speed-select: Use mailbox for CLOS_PM_QOS_CONFIGSrinivas Pandruvada1-6/+0
Use mailbox to read/write CLOS_PM_QOS_CONFIG instead of read/write to MMIO offset. Signed-off-by: Srinivas Pandruvada <[email protected]> Signed-off-by: Andy Shevchenko <[email protected]>
2019-11-07tools/power/x86/intel-speed-select: Auto mode for CLXSrinivas Pandruvada1-12/+100
There is an expectation in the CLX platform for SST base-freq feature that Scaling min frequency be different for high and low priority cores. This is the way the firmware will understand the priority. So this change will look at high priority and low priority cores, and set scaling_min_freq to P1High for high priority cores and P1Low to low priority cores.

2019-11-07tools/power/x86/intel-speed-select: Correct CLX-N frequency unitsSrinivas Pandruvada1-3/+3
In CLX_N base_frequency is read from cpufreq sysfs, where units are in KHz. The internal units in the code matches the real ratios which are in 100MHz scale. So when storing units for CLX-N frequencies, convert to 100MHz scale. Signed-off-by: Srinivas Pandruvada <[email protected]> Signed-off-by: Andy Shevchenko <[email protected]>
