* x86/platform/intel-mid: Allocate RTC interrupt for MerrifieldAndy Shevchenko2017-01-203-14/+49
| | | | | | | | | | | | | | | | | | | | | Legacy RTC requires interrupt line 8 to be dedicated for it. On Intel MID platforms the legacy PIC is absent and in order to make RTC work we need to allocate interrupt separately. Current solution brought by commit de1c2540aa4f does it in a wrong place, and since it's done unconditionally for all x86 devices, some of them, e.g. PNP based, might get it wrong because they execute the MID specific code due to x86_platform.legacy.rtc flag being set. Move intel_mid_legacy_rtc_init() to its own module and call it before x86 RTC CMOS initialization.

It got delayed due to a newly reported and anlyzed variant of BIOS bug and the resulting wreckage: - Seperation of TSC being marked realiable and the fact that the platform provides the TSC frequency via CPUID/MSRs and making use for it for GOLDMONT. - TSC adjust MSR validation and sanitizing: The TSC adjust MSR contains the offset to the hardware counter. The sum of the adjust MSR and the counter is the TSC value which is read via RDTSC. On at least two machines from different vendors the BIOS sets the TSC adjust MSR to negative values. This happens on cold and warm boot. While on cold boot the offset is a few milliseconds, on warm boot it basically compensates the power on time of the system. The BIOSes are not even using the adjust MSR to set all CPUs in the package to the same offset. The offsets are different which renders the TSC unusable, What's worse is that the TSC deadline timer has a HW feature^Wbug. It malfunctions when the TSC adjust value is negative or greater equal 0x80000000 resulting in silent boot failures, hard lockups or non firing timers. This looks like some hardware internal 32/64bit issue with a sign extension problem. Intel has been silent so far on the issue. The update contains sanity checks and keeps the adjust register within working limits and in sync on the package. As it looks like this disease is spreading via BIOS crapware, we need to address this urgently as the boot failures are hard to debug for users" * 'x86-timers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/tsc: Limit the adjust value further x86/tsc: Annotate printouts as firmware bug x86/tsc: Force TSC_ADJUST register to value >= zero x86/tsc: Validate TSC_ADJUST after resume x86/tsc: Validate cpumask pointer before accessing it x86/tsc: Fix broken CONFIG_X86_TSC=n build x86/tsc: Try to adjust TSC if sync test fails x86/tsc: Prepare warp test for TSC adjustment x86/tsc: Move sync cleanup to a safe place x86/tsc: Sync test only for the first cpu in a package x86/tsc: Verify TSC_ADJUST from idle x86/tsc: Store and check TSC ADJUST MSR x86/tsc: Detect random warps x86/tsc: Use X86_FEATURE_TSC_ADJUST in detect_art() x86/tsc: Finalize the split of the TSC_RELIABLE flag x86/tsc: Set TSC_KNOWN_FREQ and TSC_RELIABLE flags on Intel Atom SoCs x86/tsc: Mark Intel ATOM_GOLDMONT TSC reliable x86/tsc: Mark TSC frequency determined by CPUID as known x86/tsc: Add X86_FEATURE_TSC_KNOWN_FREQ flag

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TSC on Intel Atom SoCs capable of determining TSC frequency by MSR is reliable and the frequency is known (provided by HW).

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit cc7cc02bada8 ("PCI: Query platform firmware for device power state") augmented struct pci_platform_pm_ops with a ->get_state hook and implemented it for acpi_pci_platform_pm, the only pci_platform_pm_ops existing till v4.7. However v4.8 introduced another pci_platform_pm_ops for Intel Mobile Internet Devices with commit 5823d0893ec2 ("x86/platform/intel-mid: Add Power Management Unit driver"). It is missing the ->get_state hook, which is fatal since pci_set_platform_pm() enforces its presence. Andy Shevchenko reports that without the present commit, such a device "crashes without even a character printed out on serial console and reboots (since watchdog)". Retrofit mid_pci_platform_pm with the missing callback to fix the breakage.

| * rtc: cmos: move mc146818rtc code out of asm-generic/rtc.hArnd Bergmann2016-06-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drivers should not really include stuff from asm-generic directly, and the PC-style cmos rtc driver does this in order to reuse the mc146818 implementation of get_rtc_time/set_rtc_time rather than the architecture specific one for the architecture it gets built for. To make it more obvious what is going on, this moves and renames the two functions into include/linux/mc146818rtc.h, which holds the other mc146818 specific code. Ideally it would be in a .c file, but that would require extra infrastructure as the functions are called by multiple drivers with conflicting dependencies. With this change, the asm-generic/rtc.h header also becomes much more generic, so it can be reused more easily across any architecture that still relies on the genrtc driver. The only caller of the internal __get_rtc_time/__set_rtc_time functions is in arch/alpha/kernel/rtc.c, and we just change those over to the new naming.

* | x86/platform: Audit and remove any unnecessary uses of module.hPaul Gortmaker2016-07-143-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Historically a lot of these existed because we did not have a distinction between what was modular code and what was providing support to modules via EXPORT_SYMBOL and friends. That changed when we forked out support for the latter into the export.h file. This means we should be able to reduce the usage of module.h in code that is obj-y Makefile or bool Kconfig. The advantage in doing so is that module.h itself sources about 15 other headers; adding significantly to what we feed cpp, and it can obscure what headers we are effectively using. Since module.h was the source for init.h (for __init) and for export.h (for EXPORT_SYMBOL) we consider each obj-y/bool instance for the presence of either and replace as needed. One module.h was converted to moduleparam.h since the file had multiple module_param() in it, and another file had an instance of MODULE_DEVICE_TABLE deleted, since that is a no-op when builtin. Finally, the 32 bit build coverage of olpc_ofw revealed a couple implicit includes, which were pretty self evident to fix based on what gcc was complaining about.

This series of commits converts non-modular code that is using the module_init() call to hook itself into the system to instead use device_initcall(). The conversion is a runtime no-op, since module_init actually becomes __initcall in the non-modular case, and that in turn gets mapped onto device_initcall. A couple files show a larger negative diffstat, representing ones that had a module_exit function that we remove here vs previously relying on the linker to dispose of it. We make this conversion now, so that we can relocate module_init from init.h into module.h in the future.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The X86_INTEL_MID option is bool, and hence this code is either present or absent. It will never be modular, so using module_init as an alias for __initcall is rather misleading. Fix this up now, so that we can relocate module_init from init.h into module.h in the future. If we don't do this, we'd have to add module.h to obviously non-modular code, and that would be a worse thing. Note that direct use of __initcall is discouraged, vs. one of the priority categorized subgroups. As __initcall gets mapped onto device_initcall, our use of device_initcall directly in this change means that the runtime impact is zero -- it will remain at level 6 in initcall ordering.
