x86: hpet clock enable quirk on nVidia nForce 430
this patch allows hpet=force on nVidia nForce 430 southbridge. This patch was tested by me on my old Asus A8N-VM CSM (where bios does not support hpet and does not advertise it via acpi entry). My nForce430 version: lspci -nn | grep LPC 00:0a.0 ISA bridge [0601]: nVidia Corporation MCP51 LPC Bridge [10de:0260] (rev a2) Kernel 2.6.24.3 after patching and using hpet=force reports this: dmesg | grep -i hpet Kernel command line: root=/dev/sda8 ro vga=773 video=vesafb:mtrr:4,ywrap vt.default_utf8=0 hpet=force Force enabled HPET at base address 0xfed00000 hpet clockevent registered Time: hpet clocksource has been installed. grep -i hpet /proc/timer_list Clock Event Device: hpet set_next_event: hpet_legacy_next_event set_mode: hpet_legacy_set_mode grep Clock /proc/timer_list (before patching) Clock Event Device: pit Clock Event Device: lapic grep Clock /proc/timer_list (after patching) Clock Event Device: hpet Clock Event Device: lapic Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
