2021-05-04tools/power/turbostat: Remove Package C6 Retention on Ice Lake ServerChen Yu1-6/+30
Currently the turbostat treats ICX the same way as SKX and shares the code among them. But one difference is that ICX does not support Package C6 Retention, unlike SKX and CLX. So this patch: 1. Splitting SKX and ICX in turbostat. 2. Removing Package C6 Rentention for ICX. And after this split, it would be easier to cutomize Ice Lake Server in turbostat in the future.

2021-05-04tools/power turbostat: Fix offset overflow issue in index convertingCalvin Walton1-5/+6
The idx_to_offset() function returns type int (32-bit signed), but MSR_PKG_ENERGY_STAT is u32 and would be interpreted as a negative number. The end result is that it hits the if (offset < 0) check in update_msr_sum() which prevents the timer callback from updating the stat in the background when long durations are used. The similar issue exists in offset_to_idx() and update_msr_sum(). Fix this issue by converting the 'int' to 'off_t' accordingly.

2021-05-04tools/power/turbostat: Fix turbostat for AMD Zen CPUsBas Nieuwenhuizen1-2/+6
It was reported that on Zen+ system turbostat started exiting, which was tracked down to the MSR_PKG_ENERGY_STAT read failing because offset_to_idx wasn't returning a non-negative index. This patch combined the modification from Bingsong Si and Bas Nieuwenhuizen and addd the MSR to the index system as alternative for MSR_PKG_ENERGY_STATUS.

2021-05-04tools/power turbostat: add built-in-counter for IPC -- Instructions per CycleLen Brown1-0/+84
Use linux-perf to access the hardware instructions-retired counter. This is necessary because the counter is not enabled by default, and also the counter is prone to roll-over -- both of which perf manages. It is not necessary to use perf for the cycle counter, because turbostat already needs to collect delta-aperf to calcuate frequency. Signed-off-by: Len Brown <len.brown@intel.com>

I *believed* the maintainers would pull it, given it was already under Greg's list. The patch does not introduce any bugs but is pointless and is stupid.

2021-04-23mm/filemap: fix mapping_seek_hole_data on THP & 32-bitHugh Dickins1-10/+11
No problem on 64-bit, or without huge pages, but xfstests generic/285 and other SEEK_HOLE/SEEK_DATA tests have regressed on huge tmpfs, and on 32-bit architectures, with the new mapping_seek_hole_data(). Several different bugs turned out to need fixing. u64 cast to stop losing bits when converting unsigned long to loff_t (and let's use shifts throughout, rather than mixed with * and /). Use round_up() when advancing pos, to stop assuming that pos was already THP-aligned when advancing it by THP-size. (This use of round_up() assumes that any THP has THP-aligned index: true at present and true going forward, but could be recoded to avoid the assumption.) Use xas_set() when iterating away from a THP, so that xa_index stays in synch with start, instead of drifting away to return bogus offset. Check start against end to avoid wrapping 32-bit xa_index to 0 (and to handle these additional cases, seek_data or not, it's easier to break the loop than goto: so rearrange exit from the function).

Since commit 0cc3b0ec23ce ("Clarify (and fix) in 4.13 MAX_LFS_FILESIZE macros"), MAX_LFS_FILESIZE is only a PAGE_SIZE away from wrapping 32-bit xa_index to 0, so the new find_lock_entries() has to be extra careful when handling a THP.

2021-04-22perf/x86/kvm: Fix Broadwell Xeon stepping in isolation_ucodes[]Jim Mattson1-1/+1
The only stepping of Broadwell Xeon parts is stepping 1. Fix the relevant isolation_ucodes[] entry, which previously enumerated stepping 2. Although the original commit was characterized as an optimization, it is also a workaround for a correctness issue. If a PMI arrives between kvm's call to perf_guest_get_msrs() and the subsequent VM-entry, a stale value for the IA32_PEBS_ENABLE MSR may be restored at the next VM-exit. This is because, unbeknownst to kvm, PMI throttling may clear bits in the IA32_PEBS_ENABLE MSR. CPUs with "PEBS isolation" don't suffer from this issue, because perf_guest_get_msrs() doesn't report the IA32_PEBS_ENABLE value.

2021-04-22arm64: dts: allwinner: Revert SD card CD GPIO for Pine64-LTSAndre Przywara1-1/+1
Commit 941432d00768 ("arm64: dts: allwinner: Drop non-removable from SoPine/LTS SD card") enabled the card detect GPIO for the SOPine module, along the way with the Pine64-LTS, which share the same base .dtsi. This was based on the observation that the Pine64-LTS has as "push-push" SD card socket, and that the schematic mentions the card detect GPIO. After having received two reports about failing SD card access with that patch, some more research and polls on that subject revealed that there are at least two different versions of the Pine64-LTS out there: - On some boards (including mine) the card detect pin is "stuck" at high, regardless of an microSD card being inserted or not. - On other boards the card-detect is working, but is active-high, by virtue of an explicit inverter circuit, as shown in the schematic. To cover all versions of the board out there, and don't take any chances, let's revert the introduction of the active-low CD GPIO, but let's use the broken-cd property for the Pine64-LTS this time. That should avoid regressions and should work for everyone, even allowing SD card changes now. The SOPine card detect has proven to be working, so let's keep that GPIO in place.

2021-04-22pinctrl: core: Show pin numbers for the controllers with base = 0Andy Shevchenko1-6/+8
The commit f1b206cf7c57 ("pinctrl: core: print gpio in pins debugfs file") enabled GPIO pin number and label in debugfs for pin controller. However, it limited that feature to the chips where base is positive number. This, in particular, excluded chips where base is 0 for the historical or backward compatibility reasons. Refactor the code to include the latter as well.
