-Processors based on the Zen microarchitecture support IOPORT based deeper
-C-states. The idle driver reads the acpi_gbl_FADT.xpm_timer_block.address
-in the IOPORT based C-state exit path which is claimed to be a
-"Dummy wait op" and has been around since ACPI introduction to Linux
-dating back to Andy Grover's Mar 14, 2002 posting [1].
-The comment above the dummy operation was elaborated by Andreas Mohr back
-in 2006 in commit b488f02156d3d ("ACPI: restore comment justifying 'extra'
-P_LVLx access") [2] where the commit log claims:
-"this dummy read was about: STPCLK# doesn't get asserted in time on
-(some) chipsets, which is why we need to have a dummy I/O read to delay
-further instruction processing until the CPU is fully stopped."
-
-However, sampling certain workloads with IBS on AMD Zen3 system shows
-that a significant amount of time is spent in the dummy op, which
-incorrectly gets accounted as C-State residency. A large C-State
-residency value can prime the cpuidle governor to recommend a deeper
-C-State during the subsequent idle instances, starting a vicious cycle,
-leading to performance degradation on workloads that rapidly switch
-between busy and idle phases.
-
-One such workload is tbench where a massive performance degradation can
-be observed during certain runs. Following are some statistics gathered
-by running tbench with 128 clients, on a dual socket (2 x 64C/128T) Zen3
-system with the baseline kernel, baseline kernel keeping C2 disabled,
-and baseline kernel with this patch applied keeping C2 enabled:
-
-baseline kernel was tip:sched/core at
-commit f3dd3f674555 ("sched: Remove the limitation of WF_ON_CPU on
-wakelist if wakee cpu is idle")
-
-Kernel : baseline baseline + C2 disabled baseline + patch
-
-Min (MB/s) : 2215.06 33072.10 (+1393.05%) 33016.10 (+1390.52%)

-AMean CoefVar : 78.07% 2.02% 2.60%
-
-The data shows there are edge cases that can cause massive regressions
-in case of tbench. Profiling the bad runs with IBS shows a significant
-amount of time being spent in acpi_idle_do_entry method:
-
-Overhead Command Shared Object Symbol

- ...
-
-Annotation of acpi_idle_do_entry method reveals almost all the time in
-acpi_idle_do_entry is spent on the port I/O in wait_for_freeze():
-
- 0.14 │ in (%dx),%al # <------ First "in" corresponding to inb(cx->address)
- 0.51 │ mov 0x144d64d(%rip),%rax
- 0.00 │ test $0x80000000,%eax

- 0.00 │62: mov -0x8(%rbp),%r12
- 0.00 │ leave
- 0.00 │ ← ret
-
-This overhead is reflected in the C2 residency on the test system where
-C2 is an IOPORT based C-State. The total C-state residency reported by
-"cpupower idle-info" on CPU0 for good and bad case over the 80s tbench
-run is as follows (all numbers are in microseconds):
-
- Good Run Bad Run
- (Baseline)
-
-POLL: 43338 6231 (-85.62%)
-C1 (MWAIT Based): 23576156 363861 (-98.45%)
-C2 (IOPORT Based): 10781218 77027280 (+614.45%)
-
-The larger residency value in bad case leads to the system recommending
-C2 state again for subsequent idle instances. The pattern lasts till the
-end of the tbench run. Following is the breakdown of "entry_method"
-passed to acpi_idle_do_entry during good run and bad run:
-
- Good Run Bad Run
- (Baseline)
-
-Number of times acpi_idle_do_entry was called: 6149573 6149050 (-0.01%)
- |-> Number of times entry_method was "ACPI_CSTATE_FFH": 6141494 88144 (-98.56%)
- |-> Number of times entry_method was "ACPI_CSTATE_HALT": 0 0 (+0.00%)
- |-> Number of times entry_method was "ACPI_CSTATE_SYSTEMIO": 8079 6060906 (+74920.49%)
-
-For processors based on the Zen microarchitecture, this dummy wait op is
-unnecessary and can be skipped when choosing IOPORT based C-States to
-avoid polluting the C-state residency information.

+Subject: [PATCH] ACPI: processor idle: Practically limit "Dummy wait"
+ workaround to old Intel systems
+
+Old, circa 2002 chipsets have a bug: they don't go idle when they are
+supposed to. So, a workaround was added to slow the CPU down and
+ensure that the CPU waits a bit for the chipset to actually go idle.
+This workaround is ancient and has been in place in some form since
+the original kernel ACPI implementation.
+
+But, this workaround is very painful on modern systems. The "inl()"
+can take thousands of cycles (see Link: for some more detailed
+numbers and some fun kernel archaeology).
+
+First and foremost, modern systems should not be using this code.
+Typical Intel systems have not used it in over a decade because it is
+horribly inferior to MWAIT-based idle.
+
+Despite this, people do seem to be tripping over this workaround on
+AMD system today.
+
+Limit the "dummy wait" workaround to Intel systems. Keep Modern AMD
+systems from tripping over the workaround. Remotely modern Intel
+systems use intel_idle instead of this code and will, in practice,
+remain unaffected by the dummy wait.

-Subject: [PATCH] bump the sensitivity of AMD SFH
-
-Bumps the sensitivity of AMD sfh gyro and accelerometers by removing the division
-operation and rebasing the units in the hid descriptor.
-This helps with the gyro deadzone of the Legion Go. Should not affect existing
-devices.
-
-Since most of the magic happens in firmware thej SFH 1.0 HID report descriptor is left untouched.

-Subject: [PATCH v2 0/5] acpi/x86: s2idle: move Display off/on calls outside
- suspend (fixes ROG Ally suspend)
-
-The following series moves the Display off/on calls outside of the suspend
-sequence, as they are performed in Windows. This fixes certain issues that appear
-in devices that use the calls and expect the kernel to be active during their
-call (especially in the case of the ROG Ally devices) and opens the possibility
-of implementing a "Screen Off" state in the future (which mirrors Windows).
-In addition, it adds a quirk table that will allow for adding delays between
-Modern Standby transitions, to help resolve racing conditions.
-
-This series requires a bit of background on how modern standby works in Windows.
-Fundamentally, it is composed of four states: "Active", "Screen Off", "Sleep",
-and "DRIPS". Here, I take the liberty of naming the state "Active", as it is
-implied in Windows documentation.
-
-When the user actively interacts with a device, it is in the "Active" state.
-The screen is on, all devices are connected, and desired software is running.
-The other 3 stages play a role once the user stops interacting with the device.
-This is triggered in two main ways: either by pressing the power button or by
-inactivity. Once either of those targets is met, the system enters Modern Standby.
-
-Modern Standby consists of an orchestration of the "Screen Off", "Sleep", and
-"DRIPS" states. Windows is free to move throughout these states until the user
-interacts with the device again, where the device will transition to being
-"Active". Moving between the states implies a transition, where Windows performs
-a set of actions. In addition, Windows can only move between adjacent states
-as follows:
-
-"Active" <-> "Screen Off" <-> "Sleep" <-> "DRIPS"
-
-"Screen Off" is the state where all active displays in the device (whether
-*virtual* or real; this means unrelated to DRM) are off. The user might still
-be interacting with the device or running programs (e.g., compiling a kernel).
-
-"Sleep" is a newer state, in which the device turns off its fan and pulses its
-power button, but still supports running software activities. As part of this,
-and to avoid overheating the device a lot of manufacturers lower the TDP (PLx)
-of the device [3; _DSM 9 description].
-
-Finally, DRIPS stands for Deepest Runtime Idle Power State, i.e. suspend.
-
-While Windows may transition from any state to any state, doing so implies
-performing all transitions to reach that state. All states other than DRIPS
-have a fully active kernel (Wifi, USB at least) and allow userspace activity.
-What changes is the extent of the activity, and whether some power consuming
-devices are turned off (this is done with Modern Standby aware drivers and
-firmware notifications). The Windows kernel suspends during the transition from
-the "Sleep" state to the "DRIPS" state. In all other states it is fully active.
-
-After finishing each transition, the kernel performs a firmware notification,
-described in the _DSM document [3]. Moving from left to right with function num.,
-we have Display Off (3; Active -> Screen Off), Sleep Entry (7; Screen Off -> Sleep),
-and Lowest Power State Entry Notification (5; LPSEN; Sleep -> DRIPS). Then, from
-right to left, we have Lowest Power State Exit Notification (6; DRIPS -> Sleep),
-Sleep Exit (8; Sleep -> Screen) and Display On (4; Screen Off -> Active).
-
-The Linux kernel is not currently Modern Standby aware but will still make these
-calls. So, what is the problem? The kernel calls all of the firmware notifications
-at the point LPSEN (5, 6) should be called, which is when the kernel is mostly
-suspended. This is a clear deviation from Windows, and causes undesirable
-behavior in certain devices, the main one focused in this patch series being
-the ROG Ally.
-
-The ROG Ally is a Modern Standby capable device (uses Secure Core too; really
-ticks all the MS boxes) and in it, the breakage is double: both Display 3,4
-calls and Sleep 7,8 calls cause issues.
-
-The Display 3,4 calls are responsible for the controller. The Display Off call
-disconnects (if powersave is off) or powers off (if powersave is on and on DC
-power) the MCU(s) responsible for the controller and deactivates the RGB of the
-device. Display On powers on or reconnects the controller respectively.
-This controller, in the Ally X, is composed of 6 HID devices that register to
-the kernel. As can be inferred, the handling of the calls during the suspend
-sequence leads to a set of undesirable outcomes, such as the controller
-soft-locking or only half of the HID devices coming back after resume.
-
-The Sleep 7,8 calls, in general, are responsible for setting a low power state
-that is safe to use while the device is sleeping, making the suspend light
-pulse, and turning off the fan. Due to a variety of race conditions, there is
-a rare occasion where the Ally EC can get stuck in its Sleep mode, where the
-TDP is 5W, and prevent increasing it until the device reboots. The sleep entries
-contain actions in the Ally, so there is a suspicion that calling them during
-DRIPS is causing issues. However, this is not the subject of this patch and
-has not been verified yet.
-
-This patch centers around moving the Display 3,4 calls outside the suspend
-sequence (which is the transition from Sleep to DRIPS in Modern Standby terms),
-and by implementing the proper locks necessary, opening up the possibility of
-making these calls as part of a more elaborate "Modern Standby"-like userspace
-suspend/wakelock implementation. As of this patch, they are only called before
-the suspend sequence, including with the possibility of adding a delay.
-
-This makes the intent of this patch primarily compatibility focused, as it aims
-to fix issues by the current implementation. And to that end it works.
-After moving the calls outside of the suspend sequence, my ROG Ally X test unit
-can suspend more than 50 times without rebooting, both with powersave on or off,
-regardless of whether it is plugged/unplugged during suspend, and still have the
-controller work with full reliability. Furthermore, in V2, after adding a slight
-delay prior to the Display Off call, the controller RGB fades to off, prior the
-device suspending and journalctl shows the controller disconnecting prior to
-the suspend sequence.
-
-I will note here that as part of developing Handheld Daemon, I have seen the
-suspend sequence of many devices. All of them disconnect the XInput controller
-during suspend, and all of them have it show up in the logs after suspend.
-The Ally controller after patch (3) is the first one to do it cleanly, before
-suspend. Therefore, in my eyes, the quirk table is about to get a lot bigger.
-
-In addition, moving the calls outside of the suspend sequence (and the validation
-work it implies) is an important first step in including "Modern Standby"-like
-features in Linux. For example, consider an endpoint /sys/power/standby, that
-allows for entering "active", "inactive" (for Screen Off; since the name causes
-too much confusion), "sleep" values. Those values will then in turn call the
-respective firmware notifications (and driver callbacks in the very future)
-for all transitions required to reach the entered state. Here, the value
-"suspend" (for DRIPS; another confusing name as it can refer to drivers) is
-missing, as userspace will never be able to see it. The kernel should support
-suspending at all standby states, orchestrating the required transitions to
-reach suspend/DRIPS and after suspend returning to the last state.
-
-Therefore, if userspace is not standby aware, the kernel will work the same way
-it works today. In addition, depending on hardware generation, certain power
-states might not be supported. It is important to inform userspace of this, as
-if the hardware does not support sleep, and userspace holds a wakelock for sleep,
-it will just overheat and drain the device battery.
-
-This series is worth backing this up with sources, so as part of it I reference
-Microsoft's documentation on Modern standby [1-3] that explains the whole
-process, including a document by Dell [7] and how to prepare for them and attach a
-repository of more than 15 device DSDT tables [4] from different manufacturers.
-This repository also contains instructions on how to decode the DSDT tables on
-a test laptop, to figure out what the _DSM calls will do on that device.
-
-Moreover, I conduct a short behavioral test in Windows with the Ally X to showcase
-the documentation empirically. The Ally is great for such a test, as it contains
-visual indicators for all Microsoft suspend points: "Display Off/On" calls are
-indicated with the Controller RGB turning off/on, "Screen Off" is indicated with
-the suspend light and fan being on, and Sleep is indicated with the suspend
-light blinking.
-
-Unfortunately, as part of this testing, I never found how to see if the device
-is actually suspended. As the ROG Ally X NOOPs on firmware notifications 5,6,
-and even though I disabled a Mouse from waking up a device, it still would wake
-up my Ally X dev unit.
-
-Referencing Microsoft's documentation, "Screen Off" is entered either through
-inactivity or by pressing the power button, so I conduct two tests: one by pressing
-the powerbutton, and one for entering Screen Off due to inactivity.
-
-1) Powerbutton test:
-When pressing the powerbutton, the screen of the Ally turns off, and the RGB of
-the controller faints to off within 1s. Following, depending on whether the
-system is plugged in, the power light and fan stay on for 5 seconds to 10 minutes.
-After this point, the power light begins to blink and the fan turns off, showing
-that the system has entered the "Sleep" state.
-
-2) Inactivity test:
-I set the Windows power settings to turn off the screen after 1 minute and wait.
-After one minute, the display turns off, and after 5 seconds, the controller RGB
-turns off. This indicates to me that "Screen Off" is not defined by the screen
-being off, but is rather characterized by it. During those 5 seconds while the
-RGB is on, I can use the controller to wake up the device. Afterwards it cannot.
-
-Those tests validate Microsoft's documentation and show that "Screen Off"
-seems to more closely correlate to lockscreen behavior (button locks instantly,
-inactivity after 5 seconds) than the screen being off. One other behavior I
-notice is that, as I look at my Ally X dev right now, with its screen off, I
-notice the RGB is still on, which is kind of bothersome, as in Windows the
-device would turn the RGB off. Whether as a side effect or planned, it is still
-a nice touch.
-
-This patch series is co-developed with help from Mario Limonciello, and, to be
-bisection friendly, is structured based on a patch series he made connecting the
-callbacks to the drm subsystem suspend [5]. It also references (already)
-upstream work by Luke Jones on Asus-wmi for the Ally controller quirk that is
-removed on patch (5) and an issue on amd-drm in 2023 in preparation for the
-work in that quirk [6]. Since patch (3) now uses part of the dmi table removed
-in patch (5), @Luke I can add you as Suggested-by.
-
-We will begin thorough testing on the patch series, and there will probably be
-a V3, where testing acknowledgements are added.

-Changes in v2:
- - Rewrote cover letter to better reflect the Windows Modern Standby sequence
- - Renamed the "screen_" callbacks to "display_" to match Microsoft's naming
- - Added attribution to Mario Limonciello and changed the text to reflect that
- - Made the screen on/off callbacks warn and bail with -EINVAL if they are
- called in the wrong order (currently impossible)
- - Changed patch 2 to not bail the suspend sequence when receiving an error
- (as these calls are not part of the suspend sequence and failing the
- suspend sequence would cause a user visible fault)
- - Fixed bug reported by Denis Benato by adding a quirk table in patch (3)
- - The ROG controllers get a slight delay after the Display Off call
- - Reworded patches to reflect that

+ Entry/Exit
+
+Add delays between the Sleep Entry and Sleep Exit calls, to avoid issues
+in devices that rely on them that need time to power off.
+
+Especially for the ROG Ally, this should allow its EC to suspend gracefully,
+avoiding issues where it is stuck in its suspend state. Since the delays
+are additive, steal some of the delay from Display On/Off.

+
+For the purposes of testing, apply the suspend delay to all devices.
+Before moving the sleep notifications outside of the suspend sequence,
+the EC NOOPed in regards to the CPU of the system (e.g., did not lower

+other Modern Standby systems are affected by the same quirk of the ROG
+Ally.
