Drop unused mpic_set_clk_ratio() and mpic_set_serial_int().
Both functions are almost nine years old[1] but still have no chance
to be called even from out-of-tree modules because they both are __init
and of course aren't exported.

Socket filter code and other subsystems with upcoming eBPF support should
not need to deal with the fact that we have CONFIG_BPF_SYSCALL defined or
not.
Having the bpf syscall as a config option is a nice thing and I'd expect
it to stay that way for expert users (I presume
Debugging of BPF programs needs some form of printk from the program,
so let programs call limited trace_printk() with %d %u %x %p modifiers only.
Similar to kernel modules, during program load verifier checks whether program
is calling bpf_trace_printk() and if so, kernel allocates trace_printk
Hi Steven,
while I have your attention please take another look :)
V7->V8:
- split addition of kprobe flag into separate patch
- switched to __this_cpu_inc in now documented trace_call_bpf()
- converted array into standalone bpf_func_proto and switch statement
(this apporach looks cleanest,
add TRACE_EVENT_FL_KPROBE flag to differentiate kprobe type of tracepoints,
since bpf programs can only be attached to kprobe type of

this example has two probes in one C file that attach to different kprove events
and use two different maps.
1st probe is x64 specific equivalent of dropmon. It attaches to kfree_skb,
retrevies 'ip' address of kfree_skb() caller and counts number of packet drops
at that 'ip' address. User space
Perf tries to find probe function addresses from map when debuginfo
could not be found.
To the first added function, the value of ref_reloc_sym was set in
maps__set_kallsyms_ref_reloc_sym() and can be obtained from
host_machine->kmaps->maps. After that, new maps are added to
One bpf program attaches to kmem_cache_alloc_node() and remembers all allocated
objects in the map.
Another program attaches to kmem_cache_free() and deletes corresponding
object from the map.
User space walks the map every second and prints any objects which are
older than 1 second.
Usage:
$
User interface:
struct perf_event_attr attr = {.type = PERF_TYPE_TRACEPOINT, .config =
event_id, ...};
event_fd = perf_event_open(,...);
ioctl(event_fd, PERF_EVENT_IOC_SET_BPF, prog_fd);
prog_fd is a file descriptor associated with BPF program previously loaded.
event_id is an ID of created
BPF C program attaches to blk_mq_start_request/blk_update_request kprobe events
to calculate IO latency.
For every completed block IO event it computes the time delta in nsec
and records in a histogram map: map[log10(delta)*10]++
User space reads this histogram map every 2 seconds and prints it as
bpf_ktime_get_ns() is used by programs to compute time delta between events
or as a timestamp

To add trace points to msr accesses we need to include
linux/tracepoint.h. Unfortunately this causes hellish include loops
when with the msr inlines in asm/msr.h, which are included all over.
I tried to fix several of them, but eventually gave up.
This patch moves the MSR
This patchkit adds proper trace points for all MSR accesses. Very useful
for PMU (perf) debugging, but also various other CPU near areas.
Updated version:
- Now traces RDPMC too
- Add benchmarks on the overhead of moving MSR access out of line

From: Andi Kleen
For debugging low level code interacting with the CPU
it is often useful to trace the MSR read/writes. This gives
a concise summary of PMU and other operations.
perf has an ad-hoc way to do this using trace_printk,
but it's somewhat limited (and also now spews ugly
messages
From: Andi Kleen
perf uses RDPMC to read the performance counters, so it's useful to trace
that too. Add a trace point for RDPMC too, similar to the existing
MSR ones. Since there is only a single call of rdpmc in the whole kernel
(in perf)
just add the trace statement to that call, instead of

Add a minimal driver for dm816x USB. This makes USB work on dm816x
without any other changes needed as it can use the existing musb_dsps
glue layer for the USB controller.
Note that this phy is different from dm814x and am335x.

In principle I like the idea of a deferrable wheel, but this
implementation is going to go nowhere.

The mutex lock is not used at all, remove it.
The *vmmc_regulator is not necessary, use a local variable in
stw481x_vmmc_regulator_probe() instead.

It can - consider somebody doing mkdir on that name right under you.
