Hello Jean, Ben, -i2c and -rt devs, during testing the Linux PREEMP_RT work (step-by-step being merged with mainline) together with I2C functionality I hit the fact that the I2C subsystem uses yield() in some of the non-happy code paths (mostly during chip / address probing etc). My (embedded) system was running a low-priority real-time work on the generic workqueue which tried to blink a LED using an I2C I/O multiplexer when I hit the BUG where this real-time task ran into the yield() of try_address(). Grepping through the I2C subsystem code there where more yield() sprinkled in, without it being clear to me why they are there. Can those yield()s please be removed, and if they are needed for some reason (??) be replaced with something equivalent? I am no longer with this particular project, I do not have the defconfig and kernel logs at my disposal.
