[PATCH net v2 0/4] avoid compiler and IQ/OQ reordering

Posted by Vimlesh Kumar 1 month ago

Utilize READ_ONCE and WRITE_ONCE APIs to prevent compiler
optimization and reordering. Ensure IO queue OUT/IN_CNT
registers are flushed. Relocate IQ/OQ IN/OUT_CNTS updates
to occur before NAPI completion, and replace napi_complete
with napi_complete_done.
