2017-08-22perf tools: Expression parser enhancements for metricsAndi Kleen
Enhance the expression parser for more complex metric formulas. - Support python style IF ELSE operators - Add an #SMT_On magic variable for formulas that depend on the SMT status. Example: 4 *( CPU_CLK_UNHALTED.THREAD_ANY / 2 ) if #SMT_on else cycles - Support MIN/MAX operations Example: min(1 , IDQ.MITE_UOPS / ( UPI * 16 * ( ICACHE.HIT + ICACHE.MISSES ) / 4.0 ) ) This is useful to fix up problems caused by multiplexing. - Support | & ^ operators - Minor cleanups and fixes - Support an \ escape for operators. This allows to specify event names like c2-residency - Support @ as an alternative for / to be able to specify pmus without conflicts with operators (like msr/tsc/ as msr@tsc@) Example: (cstate_core@c3\\-residency@ / msr@tsc@) * 100 Signed-off-by: Andi Kleen <ak@linux.intel.com> Acked-by: Jiri Olsa <jolsa@kernel.org> Link: http://lkml.kernel.org/r/20170811232634.30465-8-andi@firstfloor.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2017-08-22perf bpf: Tighten detection of BPF eventsAndi Kleen
perf stat -e cpu/uops_executed.core,cmask=1/ would be detected as a BPF source event because the .c matches the .c source BPF pattern. v2: Originally I tried to use lex lookahead, but it doesn't seem to work. This now extends the BPF pattern to match longer events, but then does an extra check in the C code to reject BPF matches that do not end with .c/.o/.obj This uses REJECT, which makes the flex scanner slower, but that shouldn't be a big problem for the perf events. Committer testing: # perf trace -e write -e /home/acme/bpf/tracepoint.c cat /etc/passwd > /dev/null 0.000 ( 0.006 ms): cat/18485 write(fd: 1, buf: 0x7f59eebe1000, count: 3494 ) ... 0.006 ( ): raw_syscalls:sys_enter:NR 1 (1, 7f59eebe1000, da6, 22, 7f59eebe0010, 0)) 0.008 ( ): perf_bpf_probe:_write:(ffffffff9626b2c0)) 0.000 ( 0.010 ms): cat/18485 ...

2017-08-22ALSA: core: Fix unexpected error at replacing user TLVTakashi Iwai
When user tries to replace the user-defined control TLV, the kernel checks the change of its content via memcmp(). The problem is that the kernel passes the return value from memcmp() as is. memcmp() gives a non-zero negative value depending on the comparison result, and this shall be recognized as an error code. The patch covers that corner-case, return 1 properly for the changed TLV.

2017-08-22drm: Release driver tracking before making the object available againChris Wilson
This is the same bug as we fixed in commit f6cd7daecff5 ("drm: Release driver references to handle before making it available again"), but now the exposure is via the PRIME lookup tables. If we remove the object/handle from the PRIME lut, then a new request for the same object/fd will generate a new handle, thus for a short window that object is known to userspace by two different handles. Fix this by releasing the driver tracking before PRIME.

2017-08-22ASoC: rt5670: Fix GPIO headset detection regressionTakashi Iwai
RT5670 codec driver and its machine driver for Intel CHT assume the implicit GPIO mapping on the index 0 while BIOS on most devices don't provide it. The recent commit f10e4bf6632b ("gpio: acpi: Even more tighten up ACPI GPIO lookups") restricts such cases and it resulted in a regression where the headset jack setup fails like: rt5670 i2c-10EC5672:00: ASoC: Cannot get gpio at index 0: -2 rt5670 i2c-10EC5672:00: Adding jack GPIO failed For fixing this, we need to provide the GPIO mapping explicitly in the machine driver.

We assume that each board has 4 heads for GF119+. However this is not necessarily true - in the case of a GP108 board, the register indicated that there were only 2.
