2015-09-28xen: use correct type for HYPERVISOR_memory_op()Juergen Gross2-3/+3
HYPERVISOR_memory_op() is defined to return an "int" value. This is wrong, as the Xen hypervisor will return "long". The sub-function XENMEM_maximum_reservation returns the maximum number of pages for the current domain. An int will overflow for a domain configured with 8TB of memory or more. Correct this by using the correct type. Signed-off-by: Juergen Gross <[email protected]> Signed-off-by: David Vrabel <[email protected]>
2015-09-28Revert "KVM: x86: zero kvmclock_offset when vcpu0 initializes kvmclock ↵Radim Krčmář2-4/+1
system MSR" Shifting pvclock_vcpu_time_info.system_time on write to KVM system time MSR is a change of ABI. Probably only 2.6.16 based SLES 10 breaks due to its custom enhancements to kvmclock, but KVM never declared the MSR only for one-shot initialization. (Doc says that only one write is needed.) This reverts commit b7e60c5aedd2b63f16ef06fde4f81ca032211bc5. And adds a note to the definition of PVCLOCK_COUNTS_FROM_ZERO.

2015-09-28watchdog: iTCO: Fix dependencies on I2CGuenter Roeck1-1/+2
If I2C is built as module, the iTCO watchdog driver must be built as module as well. I2C_I801 must only be selected if I2C is configured. This fixes the following build errors, seen if I2C=m and ITCO_WDT=y. i2c-i801.c:(.text+0x2bf055): undefined reference to `i2c_del_adapter' i2c-i801.c:(.text+0x2c13e0): undefined reference to `i2c_add_adapter' i2c-i801.c:(.text+0x2c17bd): undefined reference to `i2c_new_device' Fixes: 2a7a0e9bf7b3 ("watchdog: iTCO_wdt: Add support for TCO on Intel Sunrisepoint") Reviewed-by: Matt Fleming <[email protected]> Cc: Lee Jones <[email protected]> Signed-off-by: Guenter Roeck <[email protected]> Signed-off-by: Wim Van Sebroeck <[email protected]>
2015-09-28watchdog: bcm2835: Fix poweroff behaviourNoralf Trønnes1-2/+8
Currently poweroff/halt results in a reboot on the Raspberry Pi. The firmware uses the RSTS register to know which partiton to boot from. The partiton value is spread into bits 0, 2, 4, 6, 8, 10. Partiton 63 is a special partition used by the firmware to indicate halt. The firmware made this change in 19 Aug 2013 and was matched by the downstream commit: Changes for new NOOBS multi partition booting from gsh Signed-off-by: Noralf Trønnes <[email protected]> Tested-by: Stephen Warren <[email protected]> Acked-by: Stephen Warren <[email protected]> Reviewed-by: Guenter Roeck <[email protected]> Signed-off-by: Wim Van Sebroeck <[email protected]>

2015-09-28m68k: Define asmlinkage_protectAndreas Schwab1-0/+30
Make sure the compiler does not modify arguments of syscall functions. This can happen if the compiler generates a tailcall to another function. For example, without asmlinkage_protect sys_openat is compiled into this function: sys_openat: clr.l %d0 move.w 18(%sp),%d0 move.l %d0,16(%sp) jbra do_sys_open Note how the fourth argument is modified in place, modifying the register %d4 that gets restored from this stack slot when the function returns to user-space. The caller may expect the register to be unmodified across system calls. Signed-off-by: Andreas Schwab <[email protected]> Signed-off-by: Geert Uytterhoeven <[email protected]> Cc: [email protected]

2015-09-27MIPS: Initialise MAARs on secondary CPUsPaul Burton3-3/+36
MAARs should be initialised on each CPU (or rather, core) in the system in order to achieve consistent behaviour & performance. Previously they have only been initialised on the boot CPU which leads to performance problems if tasks are later scheduled on a secondary CPU, particularly if those tasks make use of unaligned vector accesses where some CPUs don't handle any cases in hardware for non-speculative memory regions. Fix this by recording the MAAR configuration from the boot CPU and applying it to secondary CPUs as part of their bringup.

2015-09-27irqchip: mips-gic: Fix pending & mask reads for MIPS64 with 32b GIC.Paul Burton1-0/+8
gic_handle_shared_int reads the GIC interrupt pending & mask registers directly into a bitmap, which is defined as an array of unsigned longs. The GIC pending registers may be 32 bits wide if the CM is older than CM3, regardless of the bit width of the CPU, but for MIPS64 kernels the unsigned longs in the bitmap will be 64 bits wide. In this case we need to perform 2 x 32 bit reads per 64 bit unsigned long in order to avoid missing interrupts.

The VP ID of a given CPU may not match up with the CPU number used by Linux. For example, if the width of the VP part of the VP ID is wider than log2(number of VPs per core) and the system has multiple cores then this will be the case. Alternatively, if a pre-r6 system implements the MT ASE with multiple VPEs per core and Linux is built without support for the MT ASE then the numbers won't match up either.

2015-09-26tools/power turbostat: SKL: Adjust for TSC difference from base frequencyLen Brown1-2/+20
On a Skylake with 1500MHz base frequency, the TSC runs at 1512MHz. This is because the TSC is no longer in the n*100 MHz BCLK domain, but is now in the m*24MHz crystal clock domain. (24 MHz * 63 = 1512 MHz) This adds error to several calculations in turbostat, unless the TSC sample sizes are adjusted for this difference. Note that calculations in the time domain are immune from this issue, as the timing sub-system has already calibrated the TSC against a known wall clock. AVG_MHz = APERF_delta/measurement_interval need no adjustment. APERF_delta is in the BCLK domain, and measurement_interval is in the time domain. TSC_MHz = TSC_delta/measurement_interval needs no adjustment -- as we really do want to report the actual measured TSC delta here, and measurement_interval is in the accurate time domain. %Busy = MPERF_delta/TSC_delta needs adjustment to use TSC_BCLK_DOMAIN_delta. TSC_BCLK_DOMAIN_delta = TSC_delta * base_hz / tsc_hz Bzy_MHz = TSC_delta/APERF_delta/MPERF_delta/measurement_interval need adjustment as above. No other metrics in turbostat need to be adjusted. Before: CPU Avg_MHz %Busy Bzy_MHz TSC_MHz - 550 24.84 2216 1512 0 2191 98.73 2219 1514 2 0 0.01 2130 1512 1 9 0.43 2016 1512 3 2 0.08 2016 1512 After: CPU Avg_MHz %Busy Bzy_MHz TSC_MHz - 550 25.05 2198 1512 0 2190 99.62 2199 1512 2 0 0.01 2152 1512 1 9 0.46 2000 1512 3 2 0.10 2000 1512 Note that in this example, the "Before" Bzy_MHz was reported as exceeding the 2200 max turbo rate. Also, even a pinned spin loop would not be reported as over 99% busy. Signed-off-by: Len Brown <[email protected]>
2015-09-26tools/power turbostat: KNL workaround for %Busy and Avg_MHzHubert Chrzaniuk1-0/+13
KNL increments APERF and MPERF every 1024 clocks. This is compliant with the architecture specification, which requires that only the ratio of APERF/MPERF need be valid. However, turbostat takes advantage of the fact that these two MSRs increment every un-halted clock at the actual and base frequency: AVG_MHz = APERF_delta/measurement_interval %Busy = MPERF_delta/TSC_delta This quirk is needed for these calculations to also work on KNL, which would otherwise show a value 1024x smaller than expected.
