perf/x86/intel/uncore: propose to support IIO free-running counters in 4.14

by Jin, Yao

Hi, The upstream kernel has supported IIO free-running counters on Skylake server. As of Skylake Server, there are a number of free running counters in each IIO Box that collect counts of per-box IO clocks and per-port Input/Output x BW/Utilization. There are three types of IIO free-running counters on Skylake server: 1. IO CLOCKS counter: a clock of IIO box. 2. BANDWIDTH counters: count inbound(PCIe->CPU)/outbound(CPU->PCIe) bandwidth. 3. UTILIZATION counters: count input/output utilization. With these IIO free-running counters, we can get good observation for IIO traffic on Skylake server. For example, we can see the IIO inbound bandwidth (PCIe->CPU). root@skx /sys/devices# perf stat -a -e uncore_iio_free_running_2/bw_in_port0/ ^C Performance counter stats for 'system wide': 153.19 MiB uncore_iio_free_running_2/bw_in_port0/ 8.037701069 seconds time elapsed I propose to backport the patches which support IIO free-running counters to 4.14 stable kernel. perf/x86/intel/uncore: Introduce customized event_read() for client IMC uncore 2da331465f44f9618abe8837d1a68405d550b66e perf/x86/intel/uncore: Add new data structures for free running counters 927b2deb067b8b4753fc09c7a42092f43fc0c1f6 perf/x86/intel/uncore: Add infrastructure for free running counters 0e0162dfcd1fbe4c711ee86f24f966c318999603 perf/x86/intel/uncore: Support IIO free-running counters on SKX 0f519f0352e37e7d71bdce5559517c74a35f6e33 perf/x86/intel/uncore: Expose uncore_pmu_event*() functions 5a6c9d94e9ed7410142bc6fcb638a4db1895aa0c perf/x86/intel/uncore: Clean up client IMC uncore 9aae1780e7e81e54edfb70ba33ead5b0b48be009 Thanks Jin Yao

[PATCH v2 3/3] x86/kvm: use __decrypted attribute when declaring shared variables

by Brijesh Singh

The following commit: 368a540e0232 (x86/kvmclock: Remove memblock dependency) caused SEV guest regression. When SEV is active, we map the shared variables (wall_clock and hv_clock_boot) with C=0 to ensure that both the guest and the hypervisor is able to access the data. To map the variables we use kernel_physical_mapping_init() to split the large pages, but this routine fails to allocate a new page. Before the above commit, kvmclock initialization was called after memory allocator was available but now its called very early in the boot process. Recently we added a special .data..decrypted section to hold the shared variables. This section is mapped with C=0 very early. Use __decrypted attribute to put the wall_clock and hv_clock_boot in .data..decrypted section so that they are mapped with C=0.
