interacts with interrupts, query ACPI and use MWAIT for entrance into Cx sleep states. Support C1 "I/O then halt" mode. See Intel' document 302223-007 "Intelб╝ Processor Vendor-Specific ACPI Interface Specification" for description. Move the acpi_cpu_c1() function into x86/cpu_machdep.c and use it instead of inlining "sti; hlt" sequence in several places. In the acpi(4) man page, besides documenting the dev.cpu.N.cx_methods sysctl, correct the names for dev.cpu.N.{cx_usage,cx_lowest,cx_supported} sysctls. Both jkim and avg have some other patches implementing the mwait functionality; this work is unrelated. Linux does not rely on the ACPI to provide correct tables describing Cx modes. Instead, the driver has pre-defined knowledge of the CPU models, it was supplied by Intel. Tested by: pho (previous versions) Sponsored by: The FreeBSD Foundation |
