Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:
perf trace: (Arnaldo Carvalho de Melo)
- Do not require --no-syscalls to suppress strace like output, i.e.
# perf trace -e sched:*switch
will show just sched:sched_switch events, not strace-like formatted
syscall events, use --syscalls to get the previous behaviour.
If instead:
# perf trace
is used, i.e. no events specified, then --syscalls is implied and
system wide strace like formatting will be applied to all syscalls.
The behaviour when just a syscall subset is used with '-e' is unchanged:
# perf trace -e *sleep,sched:*switch
will work as before: just the 'nanosleep' syscall will be strace-like
formatted plus the sched:sched_switch tracepoint event, system wide.
- Allow string table generators to use a default header dir, allowing
use of them without parameters to see the table it generates on
stdout, e.g.:
$ tools/perf/trace/beauty/kvm_ioctl.sh
static const char *kvm_ioctl_cmds[] = {
[0x00] = "GET_API_VERSION",
[0x01] = "CREATE_VM",
[0x02] = "GET_MSR_INDEX_LIST",
[0x03] = "CHECK_EXTENSION",
<BIG SNIP>
[0xe0] = "CREATE_DEVICE",
[0xe1] = "SET_DEVICE_ATTR",
[0xe2] = "GET_DEVICE_ATTR",
[0xe3] = "HAS_DEVICE_ATTR",
};
$
See 'ls tools/perf/trace/beauty/*.sh' to see the available string
table generators.
- Add a generator for IPPROTO_ socket's protocol constants.
perf record: (Kan Liang)
- Fix error out while applying initial delay and using LBR, due to
the use of a PERF_TYPE_SOFTWARE/PERF_COUNT_SW_DUMMY event to track
PERF_RECORD_MMAP events while waiting for the initial delay. Such
events fail when configured asking PERF_SAMPLE_BRANCH_STACK in
perf_event_attr.sample_type.
perf c2c: (Jiri Olsa)
- Fix report crash for empty browser, when processing a perf.data file
without events of interest, either because not asked for in
'perf record' or because the workload didn't triggered such events.
perf list: (Michael Petlan)
- Align metric group description format with PMU event description.
perf tests: (Sandipan Das)
- Fix indexing when invoking subtests, which caused BPF tests to
get results for the next test in the list, with the last one
reporting a failure.
eBPF:
- Fix installation directory for header files included from eBPF proggies,
avoiding clashing with relative paths used to build other software projects
such as glibc. (Thomas Richter)
- Show better message when failing to load an object. (Arnaldo Carvalho de Melo)
General: (Christophe Leroy)
- Allow overriding MAX_NR_CPUS at compile time, to make the tooling
usable in systems with less memory, in time this has to be changed
to properly allocate based on _NPROCESSORS_ONLN.
Architecture specific:
- Update arm64's ThunderX2 implementation defined pmu core events (Ganapatrao Kulkarni)
- Fix complex event name parsing in 'perf test' for PowerPC, where the 'umask' event
modifier isn't present. (Sandipan Das)
CoreSight ARM hardware tracing: (Leo Yan)
- Fix start tracing packet handling.
- Support dummy address value for CS_ETM_TRACE_ON packet.
- Generate branch sample when receiving a CS_ETM_TRACE_ON packet.
- Generate branch sample for CS_ETM_TRACE_ON packet.

The periphery can't be accessed before we set the
INIT_DONE bit which initializes the device.
A previous patch added a reconfiguration of the MSI-X
tables upon resume, but at that point in the flow,
INIT_DONE wasn't set. Since the reconfiguration of the
MSI-X tables require periphery access, it failed.
The difference between WoWLAN and without WoWLAN is that
in WoWLAN, iwl_trans_pcie_d3_suspend clears the INIT_DONE
without clearing the STATUS_DEVICE_ENABLED bit in the
software status. Because of that, the resume code thinks
that the device is enabled, but the INIT_DONE bit has been
cleared.
To fix this, don't reconfigure the MSI-X tables in case
WoWLAN is enabled. It will be done in
iwl_trans_pcie_d3_resume anyway.

The rfh for 22560 devices has changed so it supports now
the same arch of using used and free lists, but different
structures to support the last.
Use the new structures, hw dependent, to manage the lists.
bd, the free list, uses the iwl_rx_transfer_desc,
in which the vid is stored in the structs' rbid
field, and the page address in the addr field.
used_bd, the used list, uses the iwl_rx_completion_desc
struct, in which the vid is stored in the structs' rbid
field.
rb_stts, the hw "write" pointer of rx is stored in a
__le16 array, in which each entry represents the write
pointer per queue.

The union TSPEC_BODY is never used as a union. The union comprises an
array of bytes and a bitfield structure, both of which are 55 bytes in
length, but the byte array is never used. As a result the union has
been truncated to the bitfield struct, which is actually used.
Additionally the typedef has been removed from the structure to clear
the checkpatch issue with defining new types. Additionally the name has
been changed to lowercase to comply with coding style.

The union is never used as a union but only as a bitfield struct.
One side of the union (u8 charData[3];) Only seems to be present to
ensure that the structures size is 3 bytes in length. That length, of
the structure is dictated by the largest element of the union, so the
byte array only dictates size if it's the largest element of the union.
The byte array and union add nothing.
The union has therefore been removed and the structure and access to
the structure simplified.
Additionally since one of the bitfield variables (ucAccessPolicy)
spans a byte boundary the base type of the bitfield has been changed
from u8 to u16. Compilers have probably moved on from having an issue
with this, call it OCD.
The changes are coding style in nature and should not impact runtime
code execution.
