tools: firmware: check for distro fallback udev cancel rule

2017-11-15T14:53:19+00:00

commit afb999cdef69148f366839e74470d8f5375ba5f1 upstream.

Some distributions (Debian, OpenSUSE) have a udev rule in place to cancel
all fallback mechanism uevents immediately. This would obviously
make it hard to test against the fallback mechanism test interface,
so we need to check for this.

selftests: firmware: send expected errors to /dev/null

2017-11-15T14:53:19+00:00

commit 880444e214cfd293a2e8cc4bd3505f7ffa6ce33a upstream.

Error that we expect should not be spilled to stdout.

Without this we get:

./fw_filesystem.sh: line 58: printf: write error: Invalid argument
./fw_filesystem.sh: line 63: printf: write error: No such device
./fw_filesystem.sh: line 69: echo: write error: No such file or directory
./fw_filesystem.sh: filesystem loading works
./fw_filesystem.sh: async filesystem loading works

With it:

./fw_filesystem.sh: filesystem loading works
./fw_filesystem.sh: async filesystem loading works

tools/power turbostat: bugfix: GFXMHz column not changing

2017-10-08T08:26:11+00:00

[ Upstream commit 22048c5485503749754b3b5daf9d99ef89fcacdc ]

turbostat displays a GFXMHz column, which comes from reading
/sys/class/graphics/fb0/device/drm/card0/gt_cur_freq_mhz

But GFXMHz was not changing, even when a manual
cat /sys/class/graphics/fb0/device/drm/card0/gt_cur_freq_mhz
showed a new value.

It turns out that a rewind() on the open file is not sufficient,
fflush() (or a close/open) is needed to read fresh values.

selftests/seccomp: Support glibc 2.26 siginfo_t.h

2017-10-05T07:44:02+00:00

commit 10859f3855db4c6f10dc7974ff4b3a292f3de8e0 upstream.

The 2.26 release of glibc changed how siginfo_t is defined, and the earlier
work-around to using the kernel definition are no longer needed. The old
way needs to stay around for a while, though.

selftests/x86/fsgsbase: Test selectors 1, 2, and 3

2017-09-13T21:13:36+00:00

commit 23d98c204386a98d9ef9f9e744f41443ece4929f upstream.

Those are funny cases.  Make sure they work.

(Something is screwy with signal handling if a selector is 1, 2, or 3.
Anyone who wants to dive into that rabbit hole is welcome to do so.)

ntb: ntb_test: ensure the link is up before trying to configure the mws

2017-08-30T08:21:55+00:00

commit 0eb46345364d7318b11068c46e8a68d5dc10f65e upstream.

After the link tests, there is a race on one side of the test for
the link coming up. It's possible, in some cases, for the test script
to write to the 'peer_trans' files before the link has come up.

To fix this, we simply use the link event file to ensure both sides
see the link as up before continuning.

NTB: ntb_test: fix bug printing ntb_perf results

2017-08-30T08:21:55+00:00

commit 07b0b22b3e58824f70b9188d085d400069ca3240 upstream.

The code mistakenly prints the local perf results for the remote test
so the script reports identical results for both directions. Fix this
by ensuring we print the remote result.

perf probe: Fix --funcs to show correct symbols for offline module

2017-08-30T08:21:50+00:00

commit eebc509b20881b92d62e317b2c073e57c5f200f0 upstream.

Fix --funcs (-F) option to show correct symbols for offline module.
Since previous perf-probe uses machine__findnew_module_map() for offline
module, even if user passes a module file (with full path) which is for
other architecture, perf-probe always tries to load symbol map for
current kernel module.

This fix uses dso__new_map() to load the map from given binary as same
as a map for user applications.

perf symbols: Robustify reading of build-id from sysfs

2017-08-07T01:59:48+00:00

[ Upstream commit 7934c98a6e04028eb34c1293bfb5a6b0ab630b66 ]

Markus reported that perf segfaults when reading /sys/kernel/notes from
a kernel linked with GNU gold, due to what looks like a gold bug, so do
some bounds checking to avoid crashing in that case.
