tools headers: Synchronize linux/bits.h with the kernel sources

2020-04-14T14:40:05+00:00

To pick up the changes in these csets:

  295bcca84916 ("linux/bits.h: add compile time sanity check of GENMASK inputs")
  3945ff37d2f4 ("linux/bits.h: Extract common header for vDSO")

To address this tools/perf build warning:

  Warning: Kernel ABI header at 'tools/include/linux/bits.h' differs from latest version at 'include/linux/bits.h'
  diff -u tools/include/linux/bits.h include/linux/bits.h

This clashes with usage of userspace's static_assert(), that, at least
on glibc, is guarded by a ifnded/endif pair, do the same to our copy of
build_bug.h and avoid that diff in check_headers.sh so that we continue
checking for drifts with the kernel sources master copy.

This will all be tested with the set of build containers that includes
uCLibc, musl libc, lots of glibc versions in lots of distros and cross
build environments.

The tools/objtool, tools/bpf, etc were tested as well.

tools headers: Adopt verbatim copy of compiletime_assert() from kernel sources

2020-04-14T14:39:28+00:00

Will be needed when syncing the linux/bits.h header, in the next cset.

tools headers UAPI: Sync drm/i915_drm.h with the kernel sources

To pick the change in:

  88be76cdafc7 ("drm/i915: Allow userspace to specify ringsize on construction")

That don't result in any changes in tooling, just silences this perf
build warning:

tools headers UAPI: Update tools's copy of drm.h headers

2020-04-14T14:02:52+00:00

Picking the changes from:

  455e00f1412f ("drm: Add getfb2 ioctl")

Silencing these perf build warnings:

  Warning: Kernel ABI header at 'tools/include/uapi/drm/drm.h' differs from latest version at 'include/uapi/drm/drm.h'
  diff -u tools/include/uapi/drm/drm.h include/uapi/drm/drm.h

Now 'perf trace' and other code that might use the
tools/perf/trace/beauty autogenerated tables will be able to translate
this new ioctl code into a string:

  $ tools/perf/trace/beauty/drm_ioctl.sh > before
  $ cp include/uapi/drm/drm.h tools/include/uapi/drm/drm.h

tools headers kvm: Sync linux/kvm.h with the kernel sources

2020-04-14T14:02:52+00:00

To pick up the changes from:

  9a5788c615f5 ("KVM: PPC: Book3S HV: Add a capability for enabling secure guests")
  3c9bd4006bfc ("KVM: x86: enable dirty log gradually in small chunks")

  29b40f105ec8 ("KVM: s390: protvirt: Add initial vm and cpu lifecycle handling")

So far we're ignoring those arch specific ioctls, we need to revisit
this at some time to have arch specific tables, etc:

  $ grep S390 tools/perf/trace/beauty/kvm_ioctl.sh
      egrep -v " ((ARM|PPC|S390)_|[GS]ET_(DEBUGREGS|PIT2|XSAVE|TSC_KHZ)|CREATE_SPAPR_TCE_64)" | \
  $

This addresses these tools/perf build warnings:

tools headers UAPI: Sync linux/fscrypt.h with the kernel sources

2020-04-14T14:02:52+00:00

To pick the changes from:

  e98ad464750c ("fscrypt: add FS_IOC_GET_ENCRYPTION_NONCE ioctl")

That don't trigger any changes in tooling.

This silences this perf build warning:

  diff -u tools/include/uapi/linux/fscrypt.h include/uapi/linux/fscrypt.h

In time we should come up with something like:

  $ tools/perf/trace/beauty/fsconfig.sh
  static const char *fsconfig_cmds[] = {
  	[0] = "SET_FLAG",
  	[1] = "SET_STRING",
  	[2] = "SET_BINARY",
  	[3] = "SET_PATH",
  	[4] = "SET_PATH_EMPTY",
  	[5] = "SET_FD",
  	[6] = "CMD_CREATE",
  	[7] = "CMD_RECONFIGURE",
  };
  $

And:

  $ tools/perf/trace/beauty/drm_ioctl.sh | head
  #ifndef DRM_COMMAND_BASE
  #define DRM_COMMAND_BASE                0x40
  #endif
  static const char *drm_ioctl_cmds[] = {
  	[0x00] = "VERSION",
  	[0x01] = "GET_UNIQUE",
  	[0x02] = "GET_MAGIC",
  	[0x03] = "IRQ_BUSID",
  	[0x04] = "GET_MAP",
  	[0x05] = "GET_CLIENT",
  $

For fscrypt's ioctls.

tools include UAPI: Sync linux/vhost.h with the kernel sources
