Change Details

Add driver for Intel Power Management Controller (PMC) found on Sunrise Point PCH chipsets. This device exposes S0ix sleep state residency counters and power management status. Sysctls provided: dev.intel_pmc_core.0.slp_s0_residency_us - Time in deepest sleep (us) dev.intel_pmc_core.0.ltr_ignore - LTR ignore mask dev.intel_pmc_core.0.pm_cfg - PM configuration register dev.intel_pmc_core.0.pm_sts - PM status register dev.intel_pmc_core.0.access_denied - Firmware lock status Supported devices for now: - Sunrise Point-LP (0x9D21) - Sunrise Point-H (0xA121) Note: Later PCH generations (Cannon Lake, Tiger Lake, ect.) have different PMC register layouts according to the datasheet and would need per-generation tables. I avoided adding untested hardware in case they have a quirk.
