** Description changed: [Impact] + The deepest CPU package C-state is PC3 after rtwpci module is loaded. [Fix] + The fix is from Realtek. + They will upstream this fix with some other fixes later. [Test] + Verified on RTL8723DE [10ec:d723] wifi card, and it enters PC10 during long idle. [Where problems could occur] + The fix is pretty simple and small, and just increases the idle/active latency value. Nothing could went wrong in this case.
