Non-blocking Bridge Access Drivers

Honored Contributor II

Has anyone heard of updated AXI bridge access drivers to allow for non-blocking access? Currently, if the low-level device isn't ready (ie a FIFO), there's no logic in place to timeout a read or report a similar problem, hence freezing Linux. 


Would love to hear any thoughts or if I'm missing something. This is using the linux-socfpga-ltsi kernel along with Yocto and the Altera-provided preloader with Quartus II 14.1 Update 1.
