2016-04-08devlink: share user_ptr pointer for both devlink and devlink_portJiri Pirko1-8/+13
Ptr to devlink structure can be easily obtained from devlink_port->devlink. So share user_ptr[0] pointer for both and leave user_ptr[1] free for other users.

2016-04-08nfp: convert .ndo_change_mtu() to prepare/commit paradigmJakub Kicinski1-6/+102
When changing MTU on running device first allocate new rings and buffers and once it succeeds proceed with changing MTU. Allocation of new rings is not really necessary for this operation - it's done to keep the code simple and because size of the extra ring memory is quite small compared to the size of buffers. Operation can still fail midway through if FW communication times out. In that case we retry with old MTU (rings). Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S.

2016-04-08nfp: sync ring state during FW reconfigurationJakub Kicinski1-29/+16
FW reconfiguration in .ndo_open()/.ndo_stop() should reset/ restore queue state. Since we need IRQs to be disabled when filling rings on RX path we have to move disable_irq() from .ndo_open() all the way up to IRQ allocation. nfp_net_start_vec() becomes trivial now so it's inlined.

2016-04-08nfp: move filling ring information to FW configJakub Kicinski1-18/+32
nfp_net_[rt]x_ring_{alloc,free} should only allocate or free ring resources without touching the device. Move setting parameters in the BAR to separate functions.

2016-04-08nfp: preallocate RX buffers early in .ndo_openJakub Kicinski1-23/+11
We want the .ndo_open() to have following structure: - allocate resources; - configure HW/FW; - enable the device from stack perspective. Therefore filling RX rings needs to be moved to the beginning of .ndo_open(). Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-04-08nfp: reorganize initial filling of RX ringsJakub Kicinski1-41/+78
Separate allocation of buffers from giving them to FW, thanks to this it will be possible to move allocation earlier on .ndo_open() path and reuse buffers during runtime reconfiguration. Similar to TX side clean up the spill of functionality from flush to freeing the ring. Unlike on TX side, RX ring reset does not free buffers from the ring. Ring reset means only that FW pointers are zeroed and buffers on the ring must be placed in [0, cnt - 1) positions.

We need to be able to disable the link state interrupt when the device is brought down. We used to just free the IRQ at the beginning of .ndo_stop(). As we now move towards more ordered .ndo_open()/.ndo_stop() paths LSC allocation should be placed in the "allocate resource" section. Since the IRQ can't be freed early in .ndo_stop(), it is disabled instead. Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-04-07samples/bpf: add tracepoint vs kprobe performance testsAlexei Starovoitov4-0/+244
the first microbenchmark does fd=open("/proc/self/comm"); for() { write(fd, "test"); } and on 4 cpus in parallel: writes per sec base (no tracepoints, no kprobes) 930k with kprobe at __set_task_comm() 420k with tracepoint at task:task_rename 730k For kprobe + full bpf program manully fetches oldcomm, newcomm via bpf_probe_read. For tracepint bpf program does nothing, since arguments are copied by tracepoint. 2nd microbenchmark does: fd=open("/dev/urandom"); for() { read(fd, buf); } and on 4 cpus in parallel: reads per sec base (no tracepoints, no kprobes) 300k with kprobe at urandom_read() 279k with tracepoint at random:urandom_read 290k bpf progs attached to kprobe and tracepoint are noop.

2016-04-07perf, bpf: allow bpf programs attach to tracepointsAlexei Starovoitov3-5/+19
introduce BPF_PROG_TYPE_TRACEPOINT program type and allow it to be attached to the perf tracepoint handler, which will copy the arguments into the per-cpu buffer and pass it to the bpf program as its first argument. The layout of the fields can be discovered by doing 'cat /sys/kernel/debug/tracing/events/sched/sched_switch/format' prior to the compilation of the program with exception that first 8 bytes are reserved and not accessible to the program. This area is used to store the pointer to 'struct pt_regs' which some of the bpf helpers will use: +---------+ | 8 bytes | hidden 'struct pt_regs *' (inaccessible to bpf program) +---------+ | N bytes | static tracepoint fields defined in tracepoint/format (bpf readonly) +---------+ | dynamic | __dynamic_array bytes of tracepoint (inaccessible to bpf yet) +---------+ Not that all of the fields are already dumped to user space via perf ring buffer and broken application access it directly without consulting tracepoint/format. Same rule applies here: static tracepoint fields should only be accessed in a format defined in tracepoint/format. The order of fields and field sizes are not an ABI.

2016-04-07perf: optimize perf_fetch_caller_regsAlexei Starovoitov2-2/+1
avoid memset in perf_fetch_caller_regs, since it's the critical path of all tracepoints. It's called from perf_sw_event_sched, perf_event_task_sched_in and all of perf_trace_##call with this_cpu_ptr(&__perf_regs[..]) which are zero initialized by perpcu init logic and subsequent call to perf_arch_fetch_caller_regs initializes the same fields on all archs, so we can safely drop memset from all of the above cases and move it into perf_ftrace_function_call that calls it with stack allocated pt_regs.
