The below patches address
- memory fragmentation issues: when several iterations of mhi controller
register/unregister happens. In our case, we have a PCIe WiFi device for
which fw is loaded everytime when 'wifi load' happens. For this, we need
to allocate 9MiB of coherent memory with 512K segment size. After several
iterations, when the memory gets fragmented and 512K segment becomes
unavailable causing alloc failure.
- debug requirements by printing critical mhi debug registers
- bug fixes to mhi_irq_handler
- RDDM timeout issue
- memory carveout for RDDM segments.
