[BUG] - Short freezes in gameplay due to MMC_CAP_AGGRESSIVE_PM on RTS525A card reader

Posted by Matthew Schwartz 1 month, 2 weeks ago

Hello,

I have several handheld devices that have a Realtek Semiconductor Co., Ltd. RTS525A PCI Express Card Reader and I am running into an issue on all of them when I try to play games off of my SanDisk Extreme PRO Micro SD cards. 

I have two SD cards, a 1TB and a 2TB model, and while playing games off of either one there are frequent freezes in gameplay. When this happens, the kernel has some mmc and rtsx errors:

As a workaround, not setting MMC_CAP_AGGRESSIVE_PM seems to resolve the issue:

I think what's happening here is that RTS525A shuts off power to the card reader when games are idle for 10 seconds or more, and then when the game goes to load new assets it has to go through the whole re-tuning process which takes 1-2 seconds. The other brands of card readers I have keep the device powered the whole time so they do not have this issue, and that's what untagging MMC_CAP_AGGRESSIVE_PM seems to mimic. 

Should I upstream the above as a quirk or is there further debugging I can assist with to find another workaround for the gameplay stutter? I've found a couple other bugs with the card reader too but I will send out separate threads to keep things organized.

Thanks!

> I think what's happening here is that RTS525A shuts off power to the card reader when games are idle for 10 seconds or more, and then when the game goes to load new assets it has to go through the whole re-tuning process which takes 1-2 seconds. The other brands of card readers I have keep the device powered the whole time so they do not have this issue, and that's what untagging MMC_CAP_AGGRESSIVE_PM seems to mimic.

Right, MMC_CAP_AGGRESSIVE_PM does exactly what you think. If there are
an idle period of no requests for the SD card, the mmc core may decide
to power-off the card for those mmc host drivers that has set
MMC_CAP_AGGRESSIVE_PM. The idea is that we want to avoid wasting power
when the card is unused, which is typically important on some battery
driven devices.

The main problem however, is that we are lacking a common policy for
how to handle this generically for all eMMC/SD cards. Ideally it
should be independent of what mmc host drivers that is managing it,
but that's not the case.

That said, without changing the code you can use sysfs to either tweak
the idle-period or to simply prevent "runtime_suspend" (meaning
power-off) for the SD card.

For example, find the corresponding device for the mmc/sd card in
sysfs and do: echo on >.../power/control to prevent runtime suspend.

Please post a formal patch, then let's discuss what to do about it.

The other brands of card readers I have keep the device powered the whole time so they do not have this issue, and that's what untagging MMC_CAP_AGGRESSIVE_PM seems to mimic.

I tried the runtime solution during debugging, however the card reader still shuts off while idle:

deck@legion-go-2 ~> cat /sys/bus/pci/drivers/rtsx_pci/0000:c0:00.0/power/control
on

deck@legion-go-2 ~> sudo cat /sys/kernel/debug/mmc0/ios
clock:          0 Hz
vdd:            0 (invalid)
bus mode:       2 (push-pull)
chip select:    0 (don't care)
power mode:     0 (off)
bus width:      0 (1 bits)
timing spec:    0 (legacy)
signal voltage: 1 (1.80 V)
driver type:    0 (driver type B)

Only removing MMC_CAP_AGGRESSIVE_PM seemed to actually work.

Will send out that patch shortly.

Ah, I misunderstood. I should have used /sys/bus/mmc/devices/mmc0:d555/power/control, that does work at runtime.

Hi Ulf, Matthew

In our Windows card reader driver, the idle period time is set to approximately 10 seconds. 
Is there any recommended way to control or configure this idle period time?
Or is it possible to introduce a capability tag that is less aggressive than MMC_CAP_AGGRESSIVE_PM?
Since most notebooks have very strict power-saving requirements during idle states, 
we are not able to avoid using the MMC_CAP_AGGRESSIVE_PM capability.

I tried adjusting pm_schedule_suspend(device, 10000); in rtsx_pcr, but this just increases the time until you inevitably run into the issue. There are some games that can go a very long time in runtime_suspend without loading new assets, but when they inevitably go into runtime_resume after say 3 or 5 minutes, this hang in gameplay seems unavoidable with MMC_CAP_AGGRESSIVE_PM in particular. I found an old laptop of mine with an RTS5261 reader and that has the same issue unless I disable MMC_CAP_AGGRESSIVE_PM.

Full disclosure: This is my first time looking at mmc/rtsx code, so I'll defer to Ulf on this.

The only other comparison I have is from card readers in other devices of mine, a Genesys Logic GL9767 in a ROG Ally X and an O2 Micro in my Steam Deck. For both of these, the card reader drivers do not seem to implement any form of runtime power management on Linux, so the experience when playing games off of them has been flawless.

Since our driver is designed to be a general-purpose driver for all readers, 
the scenarios you mentioned — ROG Ally X and Steam Deck — are gaming handheld devices.

we would recommend disabling this power-saving function(pcr->rtd3_en) through BIOS settings/guidelines.

The drivers they use were not designed to be gaming-focused either, they are general purpose.
O2 Micro has been around since before handheld gaming PCs were even a thing. Personally,
I disagree with classifying gaming as falling outside of "general purpose" parameters.

Just to clarify, is the recommendation to disable this feature for every device with a Realtek card
reader that might be used to play games from an SD card? My MSI Raider GE67HX laptop with RTS5261 has
this same freeze in gameplay if I use an SD card. Using an SD card as a portable library is very
common.

Over the past few years, the vast majority of notebook manufacturers have placed strong emphasis on power consumption, 
requiring support for S0ix with very strict power efficiency targets.
As a result, we updated the driver to further reduce power consumption.

To address this issue, it seems necessary to provide a mechanism that allows games or user-mode applications to dynamically enable or disable the power-management (PM) functionality.

I have looped in the linux-block list and a couple of maintainers for
other block devices, to see how if they may have some input around
this topic.

Jens, Bart, Christoph, let me summarize:

For eMMC/SD, we have implemented runtime PM support for the card to
allow us to save power by putting the card into a low power state when
card has been idle for some period (3s is the default idle-period).

When we introduced this code in the mmc core several years ago, it was
kind of experimental, so we decided to have it default disabled. To
enable it, the mmc host driver needs to set a specific capability flag
(MMC_CAP_AGGRESSIVE_PM), statically at build-time (probably a not the
best idea in hindsight, but the use is still quite limited).

Now, to the problem. For the rtsx_pci_sdmmc mmc driver
MMC_CAP_AGGRESSIVE_PM is set. This works fine for most use-cases and
helps to save power, although for some gaming use-cases this fails.
More precisely, restoring the power to card introduces latency (of
course) - and this latency isn't acceptable for gaming.

To address the problem, there are a couple of ways for user space via
sysfs to control the behaviour.
1) It can prevent runtime suspend of the card via sysfs, before the
gaming use-case starts.
2) It can put a PM QoS latency constraint to prevent the lower power
state of the card (we don't obey to these constraints in the mmc core
today, but we could extend it to do it).
3) Increase the runtime PM idle period of the card (may not be
sufficient for gaming, but still an option for user space).

Another, completely different option is to change the behavior in the
mmc core, to default keep the card runtime resumed until user-space
allows runtime suspend via sysfs.

How does other block device drivers do this? What are their default
behaviors in regards to runtime PM?

[...]

Kind regards
Uffe

The role of the Linux kernel is to provide mechanisms while remaining as
policy-neutral as possible. In other words, it is up to user space to
decide whether to enable or to disable runtime PM.

For UFS devices some form of runtime PM is enabled by default for
battery-powered devices because otherwise the impact on battery life
would be unacceptable. If the latency impact of runtime resume is not
acceptable for some applications then it is up to user space software to
tune runtime power management as necessary.

Additionally, cpu_latency_qos_update_request() is called by the UFS
driver during runtime suspend and resume to prevent that CPU frequency
scaling negatively affects UFS processing latency. I'd like to move
these cpu_latency_qos_update_request() calls from the UFS driver into
the block layer core because I think that every block driver that
supports runtime power management needs this.

Bart.

I agree.

Seems reasonable to me, but how do we distinguish that it's a
battery-powered device?

Are we considering UFS a technology that is used solely for
battery-powered devices or is there something else we consider?

While this is more about performance tuning rather than I/O request
latency in regards to runtime PM, I certainly agree that this belongs
in the common block code.

Although, a tricky part when moving it upwards into the more common
layers, is that those latency constraint values may have a very
different impact, as the numbers are platform specific, right?

Thanks a lot for your comments!

Kind regards

RPM can be enabled or disabled from the scripts executed during boot.
At build time it should be known whether or not the device is battery-
powered.

I think there are devices that use UFS and that are not battery-powered,
e.g. smart TVs.

 From the UFS driver:

cpu_latency_qos_update_request(&hba->pm_qos_req, on ?
                                0 : PM_QOS_DEFAULT_VALUE);

In other words, if no block I/O is ongoing the CPU latency is set to
PM_QOS_DEFAULT_VALUE (-1 or no constraint) and if block I/O is ongoing
the maximum CPU latency is set to 0 (no CPU power savings allowed). I
think these parameters are independent of the platform and storage
device :-)

Okay, so user space needs to make a decision, no matter what.

The point here from my side, is that the default behaviour differs
(RPM suspend may be allowed at boot - or not), based on the storage
subsystem in charge of the device.

I wonder if it would make sense to try to align the behaviour to
common default, between the subsystems that have enabled support RPM.
Or maybe it's just too late for that.

I see, thanks for sharing the details! :-)

I guess the question then is, do we always want zero latency, which I
assume must be costly from a power savings point of view. At least
during the idle period, while not serving I/O and waiting for the
device to be runtime suspended.

Block I/O latency suffers if a CPU core enters a lower power state while
waiting for an I/O completion. Hence the choice in the UFS driver for
not allowing CPU cores to enter a lower power state while any block I/O
is in progress.

Right, this seems reasonable to me too. Although, in a way it is a
policy decision, as it means favoring block I/O performance, above
trusting the cpuidle governor to pick an optimal low power state (from
performance and power point of view) for the CPUs.

The other concern I was trying to point out, is that using the runtime
PM suspend/resume callbacks for managing the QoS constraint isn't
really a good fit in my opinion, because of the potential idle period
beyond the point when I/O was completed and when we may be waiting for
the device to be runtime suspended (especially when runtime PM
autosuspend is used).

More precisely, during this idle period there is no point in keeping
the QoS constraint as it would mean potentially wasting unnecessary
energy by preventing low power states for CPUs. Ideally, I think it
would be better if we could monitor the I/O request queue to manage
the QoS constraint directly. Perhaps that is what you suggested too, I
just didn't get it. :-)

That said, speaking about runtime suspend for UFS. Is runtime PM
enabled for the UFS card too or is it just the UFS host controller
that supports it?

Kind regards
Uffe

Hmm ... the block layer RPM code monitors the request queue, isn't it?
I don't see how the request queue could be monitored more directly than
how the block layer RPM code does it today - by checking the counter of
the number of requests that is in flight?

Deciding that the I/O request queue is empty is not possible without
waiting until the idle period has expired, isn't it?

It depends on the decisions made by the manufacturer of the device that
includes the UFS device.

In multiple recent UFS-powered devices RPM is enabled for both the UFS
device and the UFS host controller.

Right, this is how it works today. We would need something additional
to what we have, to allow us to better manage performance
optimizations dynamically for block I/O. Exactly how to implement
this, needs further exploring, at least from my side.

FYI, related to this, there is a series from Qcom [1], that in
principle wants to allow some of the CPUs to enter deep idle states,
while keeping others to only shallow idle states. This is especially
useful for some UFS based platforms it seems.

Okay, thanks for letting me know and taking your time to answer all my
questions!
