You would think this - but there are test suites (such as FWTS) which check hardware sleep residency; and this throws the numbers off. > It makes no sense that you, an AMD engineer, have to struggle with your o= wn > hardware. If you look at how many quirks for BIOS/EC issues I've developed over the y= ears unfortunately the reality is that many OEMs don't test Linux. The ones tha= t do find issues like this and fix them in their firmware. They often have litt= le, or no quirks and things work out of the box. > Perhaps AMD could really push for a certification program for the EC.=20 I don't really know what a "certification program" would do that a simple series of manual tests wouldn't do. Adding a test case of "boot system on battery", "suspend system", "plug in AC", "resume system", "check performan= ce" would catch this. But anyway - that's a business discussion not a technical one. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
