clocksource/drivers: Continue making Hyper-V clocksource ISA agnostic

2019-07-03T09:00:59+00:00

Continue consolidating Hyper-V clock and timer code into an ISA
independent Hyper-V clocksource driver.

Move the existing clocksource code under drivers/hv and arch/x86 to the new
clocksource driver while separating out the ISA dependencies. Update
Hyper-V initialization to call initialization and cleanup routines since
the Hyper-V synthetic clock is not independently enumerated in ACPI.

Update Hyper-V clocksource users in KVM and VDSO to get definitions from
the new include file.

No behavior is changed and no new functionality is added.

clocksource/drivers: Make Hyper-V clocksource ISA agnostic

2019-07-03T09:00:59+00:00

Hyper-V clock/timer code and data structures are currently mixed
in with other code in the ISA independent drivers/hv directory as
well as the ISA dependent Hyper-V code under arch/x86.

Consolidate this code and data structures into a Hyper-V clocksource driver
to better follow the Linux model. In doing so, separate out the ISA
dependent portions so the new clocksource driver works for x86 and for the
in-process Hyper-V on ARM64 code.

To start, move the existing clockevents code to create the new clocksource
driver. Update the VMbus driver to call initialization and cleanup routines
since the Hyper-V synthetic timers are not independently enumerated in
ACPI.

No behavior is changed and no new functionality is added.

Merge branch 'timers/vdso' into timers/core

2019-07-03T08:50:21+00:00

so the hyper-v clocksource update can be applied.

clocksource/drivers/davinci: Add support for clockevents

2019-06-25T18:46:14+00:00

Currently the clocksource and clockevent support for davinci platforms
lives in mach-davinci. It hard-codes many things, uses global variables,
implements functionalities unused by any platform and has code fragments
scattered across many (often unrelated) files.

Implement a new, modern and simplified timer driver and put it into
drivers/clocksource. We still need to support legacy board files so
export a config structure and a function that allows machine code to
register the timer.

The timer we're using is 64-bit but can be programmed in dual 32-bit
mode (both chained and unchained).

On all davinci SoCs except for da830 we're using both halves. Lower half
for clockevents and upper half for clocksource. On da830 we're using the
lower half for both with the help of a compare register.

This patch contains the core code and support for clockevent. The
clocksource code will be included in a subsequent patch.

clocksource/arm_arch_timer: Store physical timer IRQ number for KVM on VHE

2019-02-19T21:05:22+00:00

A host running in VHE mode gets the EL2 physical timer as its time
source (accessed using the EL1 sysreg accessors, which get re-directed
to the EL2 sysregs by VHE).

The EL1 physical timer remains unused by the host kernel, allowing us to
pass that on directly to a KVM guest and saves us from emulating this
timer for the guest on VHE systems.

Store the EL1 Physical Timer's IRQ number in
struct arch_timer_kvm_info on VHE systems to allow KVM to use it.

Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2018-04-06T04:21:08+00:00

Pull ARM SoC platform updates from Arnd Bergmann:
 "This release brings up a new platform based on the old ARM9 core: the
  Nuvoton NPCM is used as a baseboard management controller, competing
  with the better known ASpeed AST2xx series.

  Another important change is the addition of ARMv7-A based chips in
  mach-stm32. The older parts in this platform are ARMv7-M based
  microcontrollers, now they are expanding to general-purpose workloads.

  The other changes are the usual defconfig updates to enable additional
  drivers, lesser bugfixes. The largest updates as often are the ongoing
  OMAP cleanups, but we also have a number of changes for the older PXA
  and davinci platforms this time.

  For the Renesas shmobile/r-car platform, some new infrastructure is
  needed to make the watchdog work correctly.

  Supporting Multiprocessing on Allwinner A80 required a significant
  amount of new code, but is not doing anything unexpected"
