Add documentation for the newly added attributes: fine_grain_control fan_speed_rpm Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>

Add additional attributes, which helps in implementing algorithm in the user space to optimize fan control. These attributes are presented in the same directory as the existing performance state attributes. Additional attributes: 1. Support of fine grain control Publish support of presence of fine grain control so that fan speed can be tuned correctly. This attribute is called "fine_grain_control". 2. fan speed Publish the actual fan rpm in sysfs. Knowing fan rpm is helpful to reduce noise level and use passive control instead. Also fan performance may not be same over time, so the same control value may not be enough to run the fan at a speed. So a feedback value of speed is helpful. This sysfs attribute is called "fan_speed_rpm". Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>

When _FIF object specifies support for fine grain control, then fan speed can be set from 0 to 100% with the recommended minimum "step size" via _FSL object. Here the control value doesn't need to match any value from _FPS object. Currently we have a simple solution implemented which just pick maximum control value from _FPS to display the actual state, but this is not optimal when there is a big window between two control values in _FPS. Also there is no way to set to any speed which doesn't match control values in _FPS. The system firmware can start the fan at speed which doesn't match any control value. To support fine grain control (when supported) via thermal sysfs: - cooling device max state is not _FPS state count but it will be 100 / _FIF.step_size Step size can be from 1 to 9. - cooling device current state is _FST.control / _FIF.step_size - cooling device set state will set the control value cdev.curr_state * _FIF.step_size plus any adjustment for 100%. By the spec, when control value do not sum to 100% because of _FIF.step_size, OSPM may select an appropriate ending Level increment to reach 100%. There is no rounding during calculation. For example if step size is 6: thermal sysfs cooling device max_state = 100/6 = 16 So user can set any value from 0-16. If the system boots with a _FST.control which is not multiples of step_size, the thermal sysfs cur_state will be based on the range. For example for step size = 6: _FST.control thermal sysfs cur_state ------------------------------------------------ 0-5 0 6-11 1 .. .. 90-95 15 96-100 16 While setting the _FST.control, the compensation will be at the last step for cur_state = 16, which will set the _FST.control to 100.

We don't need u64 to store the information about _FIF. There are two booleans (fine_grain_ctrl and low_speed_notification) and one field step_size which can take value from 1-9. There are no internal users of revision field. So convert all fields to u8, by not directly extracting the _FIF info the struct. Use an intermediate buffer to extract and assign. This will help to do u32 math using these fields. No functional changes are expected. Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>

Move the functionality of creation of sysfs attributes under acpi device to a new file fan_attr.c. This cleans up the core fan code, which just use thermal sysfs interface. The original fan.c is renamed to fan_core.c. No functional changes are expected. Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>

When user get/set cur_state fails, it should be some negative error value instead of whatever returned by acpi_evaluate_object() or from acpi_execute_simple_method(). The return value from these apis is some positive values greater than 0. For example if AE_NOT_FOUND is returned it will be "5". In other ACPI drivers, -ENODEV is returned when ACPI_FAILURE(status) is true. Do the same thing here for thermal sysfs callbacks for get and set for failures.

… systems" Commit 7f7b423 ("x86/PCI: Ignore E820 reservations for bridge windows on newer systems") fixes the touchpad not working on laptops like the Lenovo IdeaPad 3 15IIL05 and the Lenovo IdeaPad 5 14IIL05, as well as fixing thunderbolt hotplug issues on the Lenovo Yoga C940. Unfortunately it turns out that this is causing issues with suspend/resume on Lenovo ThinkPad X1 Carbon Gen 2 laptops. So, per the no regressions policy, rever this. Note I'm looking into another fix for the issues this fixed.

* acpi-pm: PM: s2idle: ACPI: Fix wakeup interrupts handling ACPI: PM: s2idle: Cancel wakeup before dispatching EC GPE ACPI: PM: Revert "Only mark EC GPE for wakeup on Intel systems"

After commit e3728b5 ("ACPI: PM: s2idle: Avoid possible race related to the EC GPE") wakeup interrupts occurring immediately after the one discarded by acpi_s2idle_wake() may be missed. Moreover, if the SCI triggers again immediately after the rearming in acpi_s2idle_wake(), that wakeup may be missed too. The problem is that pm_system_irq_wakeup() only calls pm_system_wakeup() when pm_wakeup_irq is 0, but that's not the case any more after the interrupt causing acpi_s2idle_wake() to run until pm_wakeup_irq is cleared by the pm_wakeup_clear() call in s2idle_loop(). However, there may be wakeup interrupts occurring in that time frame and if that happens, they will be missed. To address that issue first move the clearing of pm_wakeup_irq to the point at which it is known that the interrupt causing acpi_s2idle_wake() to tun will be discarded, before rearming the SCI for wakeup. Moreover, because that only reduces the size of the time window in which the issue may manifest itself, allow pm_system_irq_wakeup() to register two second wakeup interrupts in a row and, when discarding the first one, replace it with the second one. [Of course, this assumes that only one wakeup interrupt can be discarded in one go, but currently that is the case and I am not aware of any plans to change that.] Fixes: e3728b5 ("ACPI: PM: s2idle: Avoid possible race related to the EC GPE") Cc: 5.4+ <stable@vger.kernel.org> # 5.4+ Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Commit 4a9af6c ("ACPI: EC: Rework flushing of EC work while suspended to idle") made acpi_ec_dispatch_gpe() check pm_wakeup_pending(), but that is before canceling the SCI wakeup, so pm_wakeup_pending() is always true. This causes the loop in acpi_ec_dispatch_gpe() to always terminate after one iteration which may not be correct. Address this issue by canceling the SCI wakeup earlier, from acpi_ec_dispatch_gpe() itself. Fixes: 4a9af6c ("ACPI: EC: Rework flushing of EC work while suspended to idle") Signed-off-by: Rafael J.

Testing on various upcoming OEM systems shows commit 7b167c4 ("ACPI: PM: Only mark EC GPE for wakeup on Intel systems") was short sighted and the symptoms were indicative of other problems. Some OEMs do have the dedicated GPIOs for the power button but also rely upon an interrupt to the EC SCI to let the lid work. The original commit showed spurious activity on Lenovo systems: * On both Lenovo T14 and P14s the keyboard wakeup doesn't work, and sometimes the power button event doesn't work. This was confirmed on my end at that time. However further development in the kernel showed that the issue was actually the IRQ for the GPIO controller was also shared with the EC SCI. This was actually fixed by commit 2d54067 ("pinctrl: amd: Fix wakeups when IRQ is shared with SCI"). The original commit also showed problems with AC adapter: * On HP 635 G7 detaching or attaching AC during suspend will cause the system not to wakeup * On Asus vivobook to prevent detaching AC causing resume problems * On Lenovo 14ARE05 to prevent detaching AC causing resume problems * On HP ENVY x360 to prevent detaching AC causing resume problems Detaching AC adapter causing problems appears to have been a problem because the EC SCI went off to notify the OS of the power adapter change but the SCI was ignored and there was no other way to wake up this system since GPIO controller wasn't properly enabled. The wakeups were fixed by enabling the GPIO controller in commit acd47b9 ("pinctrl: amd: Handle wake-up interrupt"). I've confirmed on a variety of OEM notebooks with the following test 1) echo 1 | sudo tee /sys/power/pm_debug_messages 2) sudo systemctl suspend 3) unplug AC adapter, make sure system is still asleep 4) wake system from lid (which is provided by ACPI SCI on some of them) 5) dmesg a) see the EC GPE dispatched, timekeeping for X seconds (matching ~time until AC adapter plug out) b) see timekeeping for Y seconds until woke (matching ~time from AC adapter until lid event) 6) Look at /sys/kernel/debug/amd_pmc/s0ix_stats "Time (in us) in S0i3" = X + Y - firmware processing time Signed-off-by: Mario Limonciello <mario.limonciello@amd.com> Tested-by: Kai-Heng Feng <kai.heng.feng@canonical.com> Signed-off-by: Rafael J.

An event may have a number of uncore aliases that when added to the evlist are consecutive. If there are multiple uncore events in a group then parse_events__set_leader_for_uncore_aliase will reorder the evlist so that events on the same PMU are adjacent. The collect_all_aliases function assumes that aliases are in blocks so that only the first counter is printed and all others are marked merged. The reordering for groups breaks the assumption and so all counts are printed. This change removes the assumption from collect_all_aliases that the events are in blocks and instead processes the entire evlist.
