* ARM: 8938/1: kernel: initialize broadcast hrtimer based clock event deviceBenjamin Gaignard2019-11-161-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On platforms implementing CPU power management, the CPUidle subsystem can allow CPUs to enter idle states where local timers logic is lost on power down. To keep the software timers functional the kernel relies on an always-on broadcast timer to be present in the platform to relay the interrupt signalling the timer expiries. For platforms implementing CPU core gating that do not implement an always-on HW timer or implement it in a broken way, this patch adds code to initialize the kernel hrtimer based clock event device upon boot (which can be chosen as tick broadcast device by the kernel). It relies on a dynamically chosen CPU to be always powered-up. This CPU then relays the timer interrupt to CPUs in deep-idle states through its HW local timer device. Having a CPU always-on has implications on power management platform capabilities and makes CPUidle suboptimal, since at least a CPU is kept always in a shallow idle state by the kernel to relay timer interrupts, but at least leaves the kernel with a functional system with some working power management capabilities. The hrtimer based clock event device is unconditionally registered, but has the lowest possible rating such that any broadcast-capable HW clock event device present will be chosen in preference as the tick broadcast device.

* ARM: call of_clk_init from default time_init handlerSebastian Hesselbarth2013-09-291-12/+17
| | | | | | | | | | | | | Most DT ARM machs require common clock providers initialized before timers. Currently, arch/arm machs use .init_time to call of_clk_init right before clocksource_of_init. This prevents to remove that callback and use the default one instead. This patch adds a call to of_clk_init() to the default .init_time callback for COMMON_CLK enabled machs to allow to remove custom callbacks where applicable. While at it, also reorder includes alphabetically. Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com>

This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

* time: convert arch_gettimeoffset to a pointerStephen Warren2012-12-241-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, whenever CONFIG_ARCH_USES_GETTIMEOFFSET is enabled, each arch core provides a single implementation of arch_gettimeoffset(). In many cases, different sub-architectures, different machines, or different timer providers exist, and so the arch ends up implementing arch_gettimeoffset() as a call-through-pointer anyway. Examples are ARM, Cris, M68K, and it's arguable that the remaining architectures, M32R and Blackfin, should be doing this anyway. Modify arch_gettimeoffset so that it itself is a function pointer, which the arch initializes. This will allow later changes to move the initialization of this function into individual machine support or timer drivers. This is particularly useful for code in drivers/clocksource which should rely on an arch-independant mechanism to register their implementation of arch_gettimeoffset(). This patch also converts the Cris architecture to set arch_gettimeoffset directly to the final implementation in time_init(), because Cris already had separate time_init() functions per sub-architecture. M68K and ARM are converted to set arch_gettimeoffset to the final implementation in later patches, because they already have function pointers in place for this purpose.

| | | | | | | | | | | | | | sched_clock is supposed to be initialized early - in the recently added init_early platform hook. However, in doing so we end up calling mod_timer() before the timer lists are initialized, resulting in an oops.

| | | | | | | | | | | | | | | | | | Fix build glitches on ARM ... the only user of "rtc_lock" today is the optional PC-style "CMOS" RTC driver, the legacy SA1100 RTC driver is not even in the tree any more.

* [ARM] Provide basic printk_clock() implementationRussell King2007-01-081-0/+11
| | | | | | | | | Current sched_clock() implementations on ARM cause unbootable kernels with PRINTK_TIME support enabled. To avoid this, provide a basic printk_clock() implementation which avoids sched_clock() being called before the page tables have been set up. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [ARM] 3926/1: make timer led handle HZ != 100David Brownell2006-11-071-2/+2
| | | | | | | | | | The timer LED is unusable at HZ=large, since it's got a hard-wired value of 100 ticks per cycle; when HZ=1024 (for example) it's essentially always-on. This patch just makes that be HZ ticks per cycle. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] Fix SMP irqflags supportRussell King2006-10-281-2/+1
| | | | | | | | | The IRQ changes a while back broke the build for SMP machines. Fix up the SMP code to use set_irq_regs/get_irq_regs as appropriate. Also, fix a warning in arch/arm/kernel/time.c where 'regs' becomes unused for SMP builds. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
