Linux 7.4 Fixes AMD CPU TLB Size Reporting For Zen 5 & Newer
AI summary
Linux 7.4 đã khắc phục việc báo cáo kích thước TLB không chính xác cho các bộ xử lý AMD Zen 5 và đời mới hơn. Kể từ Zen 5, các chip Ryzen và EPYC báo cáo kích thước TLB theo bội số của 32, nhưng kernel chưa được cập nhật cho điều này, dẫn đến việc kích thước bị báo cáo thấp hơn qua /proc/cpuinfo và các interface tương tự. Bản vá được merge qua x86/cpu pull. Linux 7.4 cũng cải thiện AMD SEV với tối ưu hóa RMPOPT mang lại lợi ích cho các server EPYC Zen 6 chạy nhẹ tải và có VM được bảo mật bởi SEV, cùng với interface sysfs mới để báo cáo trạng thái AMD SEV, cả hai đều được merge qua x86/sev pull.

What is malloc doing, anyway?
malloc has a very nice and simple interface: you ask for a certain amount of memory, and you’re given a void pointer to your block of contiguous bytes that’s been magicked into existence. Once you’re done with it, you call free with the same pointer and the memory disappears into the ether.

Saving A Vintage High-Voltage Power Supply From The Scrap Heap
A Fluke Model 407 high-voltage power supply gets rescued from the scrap heap and diagnosed on video. Mr Carlson powers it up safely using an isolated transformer and a current-limited variac, avoiding the risk of full power on old components. The vacuum-tube-and-circuit-board unit shows no visible damage but its output misbehaves. Using the original schematics, he traces the fault to a single faulty capacitor in the feedback loop that keeps output voltage constant.
