  • c86c7fbc8   x86: disable hpet on shutdown ... Browse Code »

    If HPET was enabled by pci quirks, we use i8253 as initial clockevent
    because pci quirks doesn't run until pci is initialized.

    The above means the kernel (or something) is assuming HPET legacy
    replacement is disabled and can use i8253 at boot.

    If we used kexec, it isn't true. So, this patch disables HPET legacy
    replacement for kexec in machine_shutdown().

    add force_hpet boot option.

    (this will be useful to make the forced-enable quirks depend on.)

    Enable HPET later during boot, after the force detect in PCI quirks. Also add
    a call to repeat the force enabling at resume time.

  • d54bd57d6   x86: HPET force enable o ICH7 and later ... Browse Code »

    Force detect and/or enable HPET on ICH chipsets. This patch just handles the
    detection part and following patches use this information. Adds a function to
    repeat the force enabling during resume time.

    Using HPET this way, instead of PIT increases the time CPUs can reside in
    C-state when system is totally idle. On my test system with Core 2 Duo,
    average C-state residency goes up from ~20mS to ~80mS.
