Research direction
Start by locating the Raspberry Pi kernel configuration and checking how CONFIG_IOSCHED_BFQ and CONFIG_BFQ_GROUP_IOSCHED are defined. Confirm that the resulting kernel configuration enables BFQ for the reported SD card, MMC, or HDD use cases; completion means both requested options are set as specified.
Written by the indexing model from the issue text.
Description
It would be great if the Raspberry Pi kernel could enable the bfq I/O scheduler, since it gives superior responsiveness and fairer scheduling on slow devices like MMC, SD cards or HDDs.
The relevant options should be:
CONFIG_IOSCHED_BFQ=m
CONFIG_BFQ_GROUP_IOSCHED=y
Here are some relevant performance tests using bfq scheduler for blk-mq with SD cards:
