Hi all, while investigating some latency issues on my laptop I stumbled across quite large delays in the rtl8723 PHY code, which are done in IRQ disabled atomic sections, which is blocking IRQ servicing for all devices in the system. Specifically there are 3 consecutive 1ms delays in rtl8723_phy_rf_serial_read(), which is used in an IRQ disabled call path. Sadly those delays don't have any comment in the code explaining why they are needed. I hope that anyone can tell if those delays are strictly neccessary and if so if they really need to be this long. Regards, Lucas
