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.
