Hi everyone, When I set CONFIG_ACPI_PROCESSOR, CONFIG_CPU_IDLE and CONFIG_INTEL_IDLE to y then I cannot boot Xen; there is a crash. If I turn CONFIG_INTEL_IDLE off then the boot goes well and, after dom0 has booted, xenpm works and gives some sane output, see below. I have tested this with kernels 3.2 to 3.4.6. Is it impossible to use INTEL_...

...as to be parsed by domain0 kernel ACPI sub-system, and then passed to hypervisor by hypercall. To make this happen, the key point is to add hook in the kernel ACPI sub-system. Fortunately, kernel already has good abstraction, and only several places need to add hook. To be more detail, there is an acpi_processor_driver (in drivers/acpi/processor_core.c) , which all the Cx/Px parsing event will go to. This driver will call its acpi processor event handler, e.g. add/remove, start/stop, notify to handle these events. These event handlers in turn will call some library functions (in drivers/acpi/processor_perf...

Set ACPI_PROCESSOR to 'n' or not set # CONFIG_ACPI_PROCESSOR is not set" Does this mean I have acpi=none in the kernel line? I really hope not. "5.

I am working on some other bugs and perf issues - and while working I noticed that both sparse and Coverity have reported some issues with Xen drivers. Please see attached various bug-fixes that I am proposing for 3.6.

Hi, i have big trouble with a Debian Lenny dom0 and latest kernel 2.6.32.19 with xen-4.0.1rc5. Due some reason the system freezes from time to time. I used kernel 2.6.31.9 with xen-3.4.2 before. The machine doesn''t write anything to serial console so there are no errors or something like that. Perhaps there is something to see from the logs ... Hardware Board: Intel DQ45CB CPU:
