Important x86 Fixes Merged Ahead Of Linux 7.3-rc4

A batch of x86/x86_64 fixes has been merged ahead of the Linux 7.3-rc4 release. The kernel now blocks loading Intel Granite Rapids microcode revision 0x1000405 or later unless the system has already been updated to that revision, avoiding a machine check exception documented as errata GNR98 and GNR101. Also fixed is Intel FRED on Panther Lake causing games to crash or freeze under Wine/Steam Play, and a CONFIG_X86_NATIVE_CPU issue where native-optimized kernel builds triggered problematic Advanced Performance Extensions (APX) extended register use on upcoming Intel platforms; the kernel now explicitly blocks APX/EGPR use until proper in-kernel support lands.

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.
