[Bug 58397] New: Missing power_supply class attributes for NtPowerInformation blocks threads and causes fps stutter
by WineHQ Bugzilla 20 Jun '25

20 Jun '25

http://bugs.winehq.org/show_bug.cgi?id=58397 Bug ID: 58397 Summary: Missing power_supply class attributes for NtPowerInformation blocks threads and causes fps stutter Product: Wine Version: unspecified Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: ntdll Assignee: wine-bugs(a)winehq.org Reporter: rtdiasmendes(a)gmail.com Distribution: Mint Created attachment 78805 --> http://bugs.winehq.org/attachment.cgi?id=78805 logs mentioned in the bug Description Affected Application: - Tainted Grail: Fall of Avalon Observed Symptoms: - Frametime spikes from ~5ms to ~100ms occurring at ~1Hz intervals. - GPU frame dispatch (via DXVK) is delayed due to thread blocking in Wine’s battery status polling logic. Performance Analysis (see attached logs): - strace shows constant, repeated attempts to read nonexistent files in /sys/class/power_supply/BAT1/ - perf stat reveals ~8,270 openat() syscalls in 10 second window (on game title screen). - perf record/report shows significant thread time consumed inside NtPowerInformation-related logic in ntdll. Root Cause: - In dlls/ntdll/unix/system.c, the function fill_battery_state() (Linux version) hardcodes the use of attributes: "charge_now" "charge_full" and "current_now". - These attributes are not universally present in /sys/class/power_supply/. On some systems, particularly those using energy-based reporting (µWh), the ABI-compliant alternatives are: "energy_now", "energy_full" and "power_now". - Since Wine looks only for the "charge_*" files and fails to return expected information, the game loops the query constantly which results in openat() being used in a tight polling loop - blocking threads and causing intermittent CPU stalls that propagate to the GPU rendering pipeline. Solution 1: - Verify what attributes are present in the power_supply class. - Implement logic with supplied attributes. Solution 2: - Attempt to read the already-implemented files. - Fallback to "energy_*" if those are not present. I gather solution 1 has a more consistent impact across different systems, while solution 2 is more lightweight on systems with "charge_*" and heavier on others. Further reading: - https://docs.kernel.org/power/power_supply_class.html - https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-devices-power - https://github.com/torvalds/linux/blob/master/include/linux/power_supply.h - https://github.com/torvalds/linux/blob/master/drivers/power/supply/power_su… Note: Attribute "scope", while implemented in the kernel, is undocumented in the power_supply_class docs. Will later check if the rest of the documentation is up to date and raise the appropriate issue upstream. Until then, do not assume it correctly reflects the kernel implementation. Disclaimer: This issue was identified and reproduced using Proton-GE, Proton (Steam Runtime), Soda and Flatpak's build. I am reporting it here for visibility and discussion since it appears to originate from WineHQ’s upstream implementation of NtPowerInformation. Out-of-scope commentary: While Wine's behavior of querying /sys/class/power_supply/ on every NtPowerInformation() call correctly emulates the Windows API semantics, it has unintended performance implications on Linux. This is due to the fact that retrieving battery information from sysfs involves real filesystem I/O, including frequent failed lookups on systems that expose energy_* instead of charge_* attributes. Therefore, applications may call NtPowerInformation() without prioritizing caching or proper fallback logic as they expect the operation to have a lower-cost then it does on Linux - causing significant and unnecessary performance degradation. Will raise this for an enchancement in the proper channels. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

I attached my console output. You can reproduce the bug just by downloading the file and trying to install. I kept my terminal open for more than 3 hours beacuse the process is "running" and if I close the terminal it says that a process is still running and closing the terminal will kill it. Therefore I don't know if my console output is complete or not. If I can help in some way, just tell me! :) -- Do not reply to this email, post in Bugzilla using the above URL to reply.

Product: Wine Version: 10.10 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: dplay Assignee: wine-bugs(a)winehq.org Reporter: hibbsncc1701(a)gmail.com Distribution: --- Created attachment 78802 --> http://bugs.winehq.org/attachment.cgi?id=78802 Internet TCP/IP Connection For DirectPlay console log. When using a clean prefix in Wine 10.10, attempting to start a new game in SimCity 2000 Network Edition doesn't work. Console log complains that there are no dplay service providers registered, despite the Connection Method dialog showing multiple dplay transports to use. Selecting the "Internet TCP/IP Connection For DirectPlay" or "Serial" option causes the game to spawn it's server process which then fails after displaying the error dialog: "Failed to initialize DirectPlay." Exiting the server app causes a segfault. Selecting the "Internet" option causes the the game to spawn it's server process which then locks up after throwing a seh error in the console. Requiring it to be killed manually. Selecting any other option causes the same behavior as the "Internet TCP/IP Connection For DirectPlay", with additional error messages for unavailable networks. (I don't have an IPX or Modem connection to test with.) Console logs attached. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

http://bugs.winehq.org/show_bug.cgi?id=58107 Bug ID: 58107 Summary: PlayOnline Viewer: Minimised window restores behaving as if it was inactive. Product: Wine Version: 10.5 Hardware: x86-64 URL: https://web.archive.org/web/20210810150839/http://www. playonline.com/ff11eu/download/media/install_win.html OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: winex11.drv Assignee: wine-bugs(a)winehq.org Reporter: chiitoo(a)gentoo.org Regression SHA1: 3ae66c75cf443c0be403d9fe4e4da3c19b3ad9a8 Distribution: Gentoo After 3ae66c75cf4 [1], PlayOnline Viewer sometimes restores from a minimised state behaving as if it was not the active window. Normally, when the PlayOnline Viewer window is visible but not the active window, it will lower its FPS to ~5 and the mouse cursor will not change over it, nor do the buttons respond to the cursor until the window is activated. Once it is the active window, the FPS for me will be above 40 depending on what is on the screen, and the mouse cursor is a custom cursor from the application. With the mentioned commit, the application window acts as if it is not the active window, with the reduced FPS and non-custom cursor, but it responds to clicks on buttons and such as usual when it is the active window. This does not happen 100% of the time, sometimes taking a handful or minimise/restore actions.

Earlier today, Arch Linux migrated over to only shipping WoW64 with its WINE builds, which appears to have borked EAC's ability to interface with the host's disk drive. A dropdown that once printed an identifier for the drive, now prints only "Adapter: 1 ID: 0" and no ability to otherwise control the program or drive. None of this is the case in Arch's build of 10.8, where Win32 is available. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
